Golfing cockatoos reveal ability to use combined tools

 

https://www.eurekalert.org/news-releases/942691

 

 News Release 8-Feb-2022
Peer-Reviewed Publication
University of Birmingham

 

Cockatoos have shown an extraordinary ability to complete a task by combining simple tools, demonstrating that this cognitive ability is not found only in primates.

-----

 In their experiment, the team devised a game of golf for one species of bird, the Goffin’s cockatoo, which is known for its problem solving skills and its ability to use single tools such as sticks to open up nut and seed shells.

The birds had to manipulate a ball through a hole into a closed box, and then use a stick to push the ball to one side of the box where it triggers a trapdoor mechanism. This in turn releases a cashew nut for the bird.

Three of the cockatoos figured out how to use the stick to manoeuvre the ball into the right position to release the treat – showing a high level of tool innovation.

Lead researcher Dr Antonio Osuna-MascarĂ³, from the University of Veterinary Medicine, in Vienna, said: “One of the most amazing aspect of the process was to observe how these animals each invented their own individual technique in how to grip the stick and hit the ball, sometimes with astonishing dexterity. One of the birds operated the stick while holding it between the mandibles, one between the beak tip and tongue and one with his claw, similar to a primate.”

Animal behaviour: Cognitive performance of four-months-old ravens may parallel adult apes


https://www.eurekalert.org/pub_releases/2020-12/sr-abc120320.php

 

News Release 10-Dec-2020
Scientific Reports

 

By four months of age the cognitive performance of ravens in experimental tasks testing their understanding of the physical world and how they interact with other ravens may be similar to those of adult great apes, according to a study published in Scientific Reports.

Simone Pika and colleagues tested the cognitive skills of eight hand-raised ravens at four, eight, 12 and 16 months of age using a series of tests. The skills the authors investigated included spatial memory, object permanence - understanding that an object still exists when it is out of sight - understanding relative numbers and addition, and the ability to communicate with and learn from a human experimenter.

The authors found that the cognitive performance of ravens was similar from four to 16 months of age, suggesting that the speed at which the ravens' cognitive skills develop is relatively rapid and near-to-complete by four months of age. At this age ravens become more and more independent from their parents and start to discover their ecological and social environments. Although task performance varied between individuals, ravens generally performed best in tasks testing addition and understanding of relative numbers and worst in tasks testing spatial memory.

Comparing the cognitive performance of the ravens with those of 106 chimpanzees and 32 orang-utans who completed similar tasks in a previous study, the authors found that with the exception of spatial memory, the cognitive performance of the ravens was very similar to those of orang-utans and chimpanzees.

Aug. 27, 2018
Hurricane Lane drenched parts of Hawaii with 3-4 feet of rainfall, with one weather station tallying the third-highest "total rainfall from a tropical cyclone in the United States since 1950," the National Weather Service says. The slow-moving storm caused floods and landslides as it moved west of the islands, back out over the Pacific Ocean.
On the Big Island, the town of Mountain View recorded 51.53 inches of rain from Wednesday to Sunday. That's the third-highest total ever measured from a U.S. storm, with the highest total being the 60.58 inches that fell on Nederland, Texas, over several days during Hurricane Harvey in 2017. The weather service says the second-highest total is the 52 inches recorded during Hurricane Hiki's hit on Hawaii in 1950.
Hilo International Airport got 36.76 inches of rain, making it "the wettest four-day period ever observed at Hilo, with records dating back to 1949," the NWS says.

Aug. 27, 2018
About 25,000 years ago in Western Europe, the last cave bear drew its final breath and the species went extinct.
But a study published on Monday in Nature Ecology & Evolution finds that some cave bear DNA lives on in modern brown bears, much like humans carry around a bit of Neanderthal.
It’s not clear why cave bears went extinct, Dr. Barlow said, although the timing roughly followed the migration pattern of anatomically modern humans from Africa into Europe. The last cave bears lived in western Europe, and at least one skeleton has been found with fragments of a human-made spear embedded in its vertebrae.

AMVETS, one of the country’s largest veterans organizations, blasted President Donald Trump on Monday over his lackluster response to the recent death of Sen. John McCain (R-Ariz.).
The organization, also known as American Veterans, tweeted that it was “deeply disappointed in the lack of traditional and appropriate respect in the White House’s reaction” to the decorated Vietnam veteran’s death.
“AMVETS is calling on the White House to show appropriate respect for the passing of Sen. McCain,” AMVETS tweeted. “He was a war hero, twice a presidential contender, and a national treasure who devoted his entire adult life to protecting and improving the American way of life.”

Aug. 27, 2018
In nearly three decades at the Justice Department, Mr. Ohr has made a career of supporting and facilitating important cases that targeted Russian organized crime. Now he is a target of President Trump, who has put his security clearance under review and attacked him publicly, and allies. They have cast Mr. Ohr and his wife — who worked as a contractor at the same research firm that produced a damaging dossier of information about Mr. Trump — as villains, part of a pro-Clinton cabal out to destroy the president.
But Mr. Ohr, 56, is far from corrupt, friends and former colleagues said. An experienced law enforcement official, he has a deep understanding of the underworld of Russian organized crime, they said, including raising concerns about at least one oligarch whose name has resurfaced amid the scrutiny of contacts between Trump associates and Russia.


https://www.yahoo.com/news/u-court-says-north-carolina-gerrymander-illegal-seeks-005935273.html
Aug. 27, 2018
A federal court ruled on Monday that North Carolina Republicans illegally drew up U.S. congressional districts in the state to benefit their party, suggesting that new lines be crafted before November's election.
The three-judge panel for the U.S. District Court for the Middle District of North Carolina said in a 321-page opinion that Republican legislators responsible for the map conducted unconstitutional partisan gerrymandering to dilute the impact of Democratic votes.
“That is precisely what the Republican-controlled North Carolina General Assembly sought to do here," the opinion said.
The panel gave parties until Thursday to file their recommendations to fix the problem.
The Republican lawmaker in charge of the plan said it was crafted to maintain Republican dominance because "electing Republicans is better than electing Democrats."
Republicans in 2016 won 10 of the 13 House districts - 77 percent of them - despite getting just 53 percent of the statewide vote, nearly the same result as in 2014.
"If this opinion stands ... the court may well order new districts be drawn in time for the 2018 elections," Rick Hasen, a professor at the University of California, Irvine, wrote on his election law blog.
"North Carolina’s gerrymandering was one of the most brazen in the nation, where state legislative leaders proudly pronounced it a partisan gerrymander," he wrote.

The Business Case for Curiosity
Most of the breakthrough discoveries and remarkable inventions throughout history, from flints for starting a fire to self-driving cars, have something in common: They are the result of curiosity. The impulse to seek new information and experiences and explore novel possibilities is a basic human attribute. New research points to three important insights about curiosity as it relates to business. First, curiosity is much more important to an enterprise’s performance than was previously thought. That’s because cultivating it at all levels helps leaders and their employees adapt to uncertain market conditions and external pressures:
although leaders might say they treasure inquisitive minds, in fact most stifle curiosity, fearing it will increase risk and inefficiency. In a survey I conducted of more than 3,000 employees from a wide range of firms and industries, only about 24% reported feeling curious in their jobs on a regular basis, and about 70% said they face barriers to asking more questions at work.


https://www.theguardian.com/environment/2018/aug/27/air-pollution-causes-huge-reduction-in-intelligence-study-reveals
Aug. 27, 2018
Air pollution causes a “huge” reduction in intelligence, according to new research, indicating that the damage to society of toxic air is far deeper than the well-known impacts on physical health.
The research was conducted in China but is relevant across the world, with 95% of the global population breathing unsafe air. It found that high pollution levels led to significant drops in test scores in language and arithmetic, with the average impact equivalent to having lost a year of the person’s education.
“Polluted air can cause everyone to reduce their level of education by one year, which is huge,” said Xi Chen at Yale School of Public Health in the US, a member of the research team. “But we know the effect is worse for the elderly, especially those over 64, and for men, and for those with low education. If we calculate [the loss] for those, it may be a few years of education.”
The damage in intelligence was worst for those over 64 years old, with serious consequences, said Chen: “We usually make the most critical financial decisions in old age.” Rebecca Daniels, from the UK public health charity Medact, said: “This report’s findings are extremely worrying.”
Air pollution causes seven million premature deaths a year but the harm to people’s mental abilities is less well known. A recent study found toxic air was linked to “extremely high mortality” in people with mental disorders and earlier work linked it to increased mental illness in children, while another analysis found those living near busy roads had an increased risk of dementia.
Air pollution was seen to have a short-term impact on intelligence as well and Chen said this could have important consequences, for example for students who have to take crucial entrance exams on polluted days.

Aug. 27, 2018
British consumers are facing a hike in food prices of at least 5% as a result of extreme weather this year, economists warn.
Extended spells of frigid and baking weather seen during the winter and summer will likely increase household food bills by an estimated £7.15 a month, the Centre for Economics and Business Research (Cebr) says.
The cold snap brought on by the Beast from the East has already been blamed for a slump in the economy at the start of the year, while some industries were adversely affected by heatwave conditions over the summer.
The Cebr said domestic food production has been hit by weather extremes that have put “particular stress on farming costs and yields”.
Between March and July, the wholesale “farm gate” prices of some staples rocketed by up to 80%.
The price of wheat for bread rose by a fifth, strawberries by 28%, carrots by 41% and lettuce by 61%.
The farm gate price of carrots rose by 80%, according to European Commission figures used by the economists.
The Cebr said: “Summer 2018 has been one of the warmest in living memory, with above average temperatures recorded since April and dry spells lasting more than 50 days in parts of the country.

New Research Shows Most Human Pregnancies End in Miscarriage
Previous research has found that somewhere between 10 and 20 percent, or as many as 1 in 4 known pregnancies end in miscarriage, also known medically as spontaneous abortion.
Many women don't even know they're pregnant initially; and, since most miscarriages happen in the first 12 weeks of pregnancy, many miscarry without even knowing it's happening.
It's these unknown miscarriages that make up the majority, according to Rice. In fact, he found that a woman in her 20s is just as likely to miscarry as carry the foetus to term.
And, because the miscarriage rate only rises with age, the number of miscarriages far outnumber live births, his analysis asserts.

President Trump really knows how to say thank you.
Just as festivities geared up for Public Service Recognition Week, which began Sunday, his administration sent a letter to Congress proposing $143.5 billion in compensation cuts for federal employees.
In a letter to House Speaker Paul D. Ryan (R-Wis.) on Friday, Office of Personnel Management Director Jeff T.H. Pon pushed four proposals that, over 10 years, would significantly cut retirement benefits for 2.6 million federal retirees and survivors.

Peter Strzok just gave a hard-to-rebut defense of the objectivity of the Russia investigation’s origins
In a written statement offered before he testified before the House Oversight Committee on Thursday, Strzok pointedly noted that there was no effort on his part to keep Trump from winning the White House — and, further, that he was one of only a few people who could have potentially leaked details from the investigation in an effort to block Trump’s victory.
“In the summer of 2016,” Strzok wrote, “I was one of a handful of people who knew the details of Russian election interference and its possible connections with members of the Trump campaign. This information had the potential to derail, and quite possibly, defeat Mr. Trump. But the thought of exposing that information never crossed my mind.”

Finally bought another copy of my favorite Origami book. I've lost or given away several copies thru the years. It took some time to track it down, because the name was changed. Luckily, I was pretty sure I remembered it was published by Dover, and their description mentioned that the original name was "Paper Folding for Beginners".
The name is now "Fun with Paper Folding and Origami", by William D. Murray and Francis J. Rigney.
Dover is a good place to look for such things.
It specializes in reissues.
The instructions are very clear and understandable. It was great on baby sitting jobs, where I didn't want to frustrate and bore the children by making them wait while I tried to figure out obscure instructions that are found in some Origami books.

Exxon Mobil Corp. said it has left the Koch-backed American Legislative Exchange Council (ALEC) following a clash over climate change policy.
Exxon Mobil was one of the leading voices against a proposal within ALEC to pressure the Environmental Protection Agency (EPA) to rescind the policy that allowed it to regulate greenhouse gas emissions. The proposal ended up getting scuttled.
ALEC has lost numerous major members over its advocacy against climate change policies, including Royal Dutch Shell, Google and Microsoft. Companies like Ford Motor Co., Expedia Group Inc., Yahoo Inc. and Yelp Inc. have recently left as well, without specifically mentioning climate change.

8 Black Lung Indictments Allege Coal Mine Managers Lied About Health Safety
The indictments, announced by U.S. Attorney Russell Coleman at an Owensboro museum that tells the long history of coal mining in this part of the country, charge that the mine personnel sought to deceive regulators with the Federal Mine Safety and Health Administration (MSHA) about the daily levels of breathable dust at two mines owned by the Armstrong Coal. The company, which was based in Madisonville, Kentucky, has since gone bankrupt but was named as an unindicted co-conspirator.

The mercurial veteran GOP political operative, Roger Stone, has acknowledged that he is the unnamed Trump campaign regular who corresponded with an alleged Russian hacker, as described in a new indictment against a dozen Russians returned Friday by a federal grand jury.
The indictment by special counsel Robert Mueller targets 12 Russian intelligence officers for engaging in a sustained effort to hack Democrats and aides to Hillary Clinton during the 2016 presidential campaign. All 12 defendants are members of Russia's intelligence service, according to the court filing.

Severe heat poses another health risk for survivors still trapped inside their homes after deadly torrential rains flooded parts of Japan this week.
After one of the worst natural disasters in the nation’s recent history, rescue workers on Friday are still trying to locate missing people in parts of western Japan as temperatures soar. At least nine people have already been reported dead during a heat wave with temperatures as high as 106 degrees Fahrenheit, which hit just as authorities began to assess the damage from flooding that poured muddy water into the streets and spurred dangerous mudslides throughout the western part of the country.

Study links nutrition to brain health and intelligence in older adults

https://www.eurekalert.org/pub_releases/2016-12/uoia-sln121316.php

Public Release: 13-Dec-2016
Study links nutrition to brain health and intelligence in older adults
University of Illinois at Urbana-Champaign

A study of older adults links consumption of a pigment found in leafy greens to the preservation of "crystallized intelligence," the ability to use the skills and knowledge one has acquired over a lifetime.

The study is reported in the journal Frontiers in Aging Neuroscience.

Lutein (LOO-teen) is one of several plant pigments that humans acquire through the diet, primarily by eating leafy green vegetables, cruciferous vegetables such as broccoli, or egg yolks, said University of Illinois graduate student Marta Zamroziewicz, who led the study with Illinois psychology professor Aron Barbey. Lutein accumulates in the brain, embedding in cell membranes, where it likely plays "a neuroprotective role," she said.

"Previous studies have found that a person's lutein status is linked to cognitive performance across the lifespan," Zamroziewicz said. "Research also shows that lutein accumulates in the gray matter of brain regions known to underlie the preservation of cognitive function in healthy brain aging."

•••••

Those with higher serum lutein levels also tended to have thicker gray matter in the parahippocampal cortex, a brain region that, like crystallized intelligence, is preserved in healthy aging, the researchers report.

"Our analyses revealed that gray-matter volume of the parahippocampal cortex on the right side of the brain accounts for the relationship between lutein and crystallized intelligence," Barbey said. "This offers the first clue as to which brain regions specifically play a role in the preservation of crystallized intelligence, and how factors such as diet may contribute to that relationship."

"Our findings do not demonstrate causality," Zamroziewicz said. "We did find that lutein is linked to crystallized intelligence through the parahippocampal cortex."

"We can only hypothesize at this point how lutein in the diet affects brain structure," Barbey said. "It may be that it plays an anti-inflammatory role or aids in cell-to-cell signaling. But our finding adds to the evidence suggesting that particular nutrients slow age-related declines in cognition by influencing specific features of brain aging."

Real-life psychopaths actually have below-average intelligence

https://www.newscientist.com/article/2118547-real-life-psychopaths-actually-have-below-average-intelligence/

By Jessica Hamzelou

Manipulative, dishonest and lacking in empathy – the traits that describe a psychopath aren’t particularly pleasant. But the idea that they are also fiendishly clever – as often portrayed in films and TV – isn’t quite true. In fact, in general, psychopaths seem to have below-average intelligence.

You have probably met a psychopath at some point in your life. They make up around 1 per cent of the population, says Brian Boutwell at St Louis University in Missouri. A person is classified as a psychopath if they achieve a certain score on a test of psychopathic traits, which include callousness, impulsiveness, aggression and a sense of grandiosity. “Not all psychopaths will break the law or hurt someone, but the odds of them doing so are higher,” says Boutwell.

Because many psychopaths are charming and manipulative, people have assumed they also have above-average intelligence, says Boutwell. Psychologists term this the “Hannibal Lecter myth”, referring to the fictional serial killer, cannibal and psychiatrist from the book and film The Silence of the Lambs.

•••••

To investigate, Boutwell and his colleagues analysed the results of 187 published studies on intelligence and psychopathy. These papers included research on psychopaths in prison as well as those enjoying high-flying careers. They also included a range of measures of intelligence.

Overall, the team found no evidence that psychopaths were more intelligent than people who don’t have psychopathic traits. In fact, the relationship went the other way. The psychopaths, on average, scored significantly lower on intelligence tests. “I think the results will surprise a lot of people,” says Boutwell.

•••••

In his experience, DeLisi says psychopaths tend to do poorly at school. “They are very sensation-seeking,” he says. “They don’t like to sit and read books – they end up engaging in substance abuse.” In his own interviews, he has found psychopaths to be rather inarticulate, and to swear a lot. “They talk over you in a brusque, aggressive style,” he says.

Alex Jones Scrubs Pizzagate Content; Complaint Reveals New Tie Connecting Shooter To Jones

Alex Jones Scrubs Pizzagate Content; Complaint Reveals New Tie Connecting Shooter To Jones
Blog ››› December 13, 2016 3:07 PM EST ››› ERIC HANANOKI

Conspiracy theorist Alex Jones is scrubbing online content pushing the false and dangerous conspiracy theory that Hillary Clinton’s campaign trafficked children through a D.C. pizzeria. A man who recently entered the pizzeria with a rifle and fired shots reportedly shared a piece of Jones’ content before the shooting; the video he shared is still on the website.

•••••

Welch also told The New York Times that he listens to Jones, and he reportedly liked Infowars on Facebook.

Jones and Infowars appear to be scrubbing commentary about pizzagate. Jones’ YouTube channel posted a November 23 video headlined “Pizzagate Is Real: Something Is Going On, But What?” The video has since “been removed by the user,” though it’s not clear when.

•••••

Jones promoted the video on his Facebook account but has since deleted the post. Infowars also deleted a November 27 article by Bowne that promoted the video.

While Jones has removed content related to pizzagate, his website still contains false articles promoting the conspiracy theory.

Watching each other helps these social insects learn to pull strings for a sugar water reward

String pulling is a popular problem-solving task for investigating cognitive abilities in vertebrates, but has never been tested in insects. Now, a social insect has joined the club, according to a study publishing October 4, 2016 in the open-access journal PLOS Biology by Lars Chittka from Queen Mary University of London, UK, and colleagues. The researchers found that bumblebees can figure out how to pull a string to get a sugar water reward, that watching this helps other bees learn to do it too, and that this new skill continues to spread through a colony even after the original string-puller is gone.

People have a remarkable ability to remember and recall events from the past, even when those events didn't hold any particular importance at the time they occurred. Now, researchers reporting in the journal Current Biology on November 23 have evidence that dogs have that kind of "episodic memory" too.

The study found that dogs can recall a person's complex actions even when they don't expect to have their memory tested.

New research finds pre-term babies fed more breast milk in the first 28 days of life had larger deep nuclear gray matter volume and better IQs, academic achievements, memory, and motor function by age 7
Brigham and Women's Hospital

A new study, which followed 180 pre-term infants from birth to age seven, found that babies who were fed more breast milk within the first 28 days of life had had larger volumes of certain regions of the brain at term equivalent and had better IQs, academic achievement, working memory, and motor function.

The findings were published online Friday, July 29, in The Journal of Pediatrics.

Cognitive ability varies, but prejudice is universal

Cognitive ability varies, but prejudice is universal
Society for Personality and Social Psychology

When it comes to prejudice, it does not matter if you are smart or not, or conservative or liberal, each group has their own specific biases. In a recent study, psychologists show that low cognitive ability (i.e., intelligence, verbal ability) was not a consistent predictor of prejudice. Cognitive ability, whether high or low, only predicts prejudice towards specific groups. The results are published in the journal Social Psychological and Personality Science.

"Very few people are immune to expressing prejudice, especially prejudice towards people they disagree with," says lead author Mark Brandt (Tilburg University, Netherlands).

Brandt and Jarret Crawford (The College of New Jersey) analyzed data from 5914 people in the United States that includes a measure of verbal ability and prejudice towards 24 different groups.

Analyzing the results, the researchers found that people with both relatively higher and lower levels of cognitive ability show approximately equal levels of intergroup bias, but towards different sets of groups. People with low cognitive ability tended to express prejudice towards groups perceived as liberal and unconventional (e.g., atheists, gays and lesbians), as well as groups of people perceived as having low choice over group membership (e.g., ethnic minorities). People with high cognitive ability showed the reverse pattern. They tended to express prejudice towards groups perceived as conservative and conventional (e.g., Christians, the military, big business).
[How do they define "prejudice"? If you are not a Christian, you have received nasty comments & behaviour from people calling themselves Christians, , and proposals to limit your rights, so of course you will have negative feelings toward them. If you are intelligent and informed, you will know that big business does do things like conceal the fact that their products are harmful, conspire to make needed medicines cost a lot, etc. I have noticed that people in various groups readily accept totally ridiculous claims towards those they don't like.]

Black bear links real objects to computer images

Black bear links real objects to computer images
Study forms part of research into the welfare of bears in captivity
Springer

American black bears may be able to recognize things they know in real life, such as pieces of food or humans, when looking at a photograph of the same thing. This is one of the findings of a study led by Zoe Johnson-Ulrich and Jennifer Vonk of Oakland University in the US, which involved a black bear called Migwan and a computer screen. The findings are published in Springer's journal Animal Cognition.

The study forms part of a broader research project into the welfare of bears in captivity. It aims to find out how the animals themselves rate the environment in which they are held, and the facilities, food and features provided to them. The goal is to assess this by presenting bears with photographs of objects. To do so, the research team first had to assess whether bears are in fact able to recognize 2-D images of objects and people familiar to them when these are presented to them on a touch screen.

With this in mind, the researchers tested the responses of an American black bear named Migwan. The bear was born in the wild, but was rescued at a very young age and rehabilitated due to injuries

•••••

It was found that Migwan was able to recognize, on a photograph, the visual features of objects or natural stimuli she already knew. It is an ability that bears share with hens, rhesus monkeys, pigeons, tortoises and horses.

"Bears can transfer learning with real objects to photographs of those objects presented on computer screens," says Johnson-Ulrich.

Make way for ducklings; they're smarter than you thought

Make way for ducklings; they're smarter than you thought
American Association for the Advancement of Science

While the brain's ability to deal with abstract properties - including patterns of "same" and "different" - has been demonstrated in animals with advanced intelligence after extensive training, researchers now show that newly hatched ducklings can distinguish same and different, too, without any training at all. The ability to identify logical relationships between objects, retain this understanding, and apply it to novel objects is known as relational concept learning. To date, such learning - often mistakenly considered uniquely human - has only been demonstrated in a few animal species, and only after extensive reinforcement training. Here, working with ducklings, Antone Martinho III and Alex Kacelnik created a behavioral test involving the familiar social learning phenomenon of imprinting, one of the first things a naive brain learns to do (often in order to identify a parent). In the test, the first sight to which the newly hatched mallards were exposed was a pair of objects that were either the same or different in shape or color; later, when shown new pairs of objects, these ducklings preferred to follow pairs exhibiting the same relation on which they had originally imprinted. Thus, even imprinting, a most basic form of learning, appears to be shaped by higher level cognitive reasoning, the researchers say. In the wild, a young duckling being competent in relational thinking increases the likelihood that he will identify his mother and siblings, despite all variables the environment presents, the authors say.

Stupidity paradox -- why smart people don't think too much at work

One problem is that some bosses feel threatened by intelligent employees.

Stupidity paradox -- why smart people don't think too much at work
Lund University

Intelligent people don't often think critically at work, as this is often uncomfortable. When a culture of "functional stupidity" prevails, it leads to a huge waste of resources, says Professor of Business Administration Mats Alvesson at Lund University, Sweden, who has written a book on the phenomenon of functional stupidity.

•••••

"Organisations suffer from a reflection deficit. Questions that are critical are seen as uncomfortable and therefore we assume flexible positions, making an effort to ensure that nobody can criticise us. We then end up in a situation where everyone does the right thing, everyone is positive, and all things seem to be in order when in fact they are not", says Mats Alvesson.

Together with André Spicer from Cass Business School in London, Mats Alvesson shows a variety of examples of what happens when symbolic activities and what we display become more important than what we actually do - and the room for individual thought and responsibility is decreased.

Monkeys in Brazil 'have used stone tools for hundreds of years at least'

Monkeys in Brazil 'have used stone tools for hundreds of years at least'
Was early human behavior influenced by their observations of monkeys using stone tools?
University of Oxford

New archaeological evidence suggests that Brazilian capuchins have been using stone tools to crack open cashew nuts for at least 700 years. Researchers say, to date, they have found the earliest archaeological examples of monkey tool use outside of Africa. In their paper, published in Current Biology, they suggest it raises questions about the origins and spread of tool use in New World monkeys and, controversially perhaps, prompts us to look at whether early human behaviour was influenced by their observations of monkeys using stones as tools. The research was led by Dr Michael Haslam of the University of Oxford, who in previous papers presents archaeological evidence showing that wild macaques in coastal Thailand used stone tools for decades at least to open shellfish and nuts.

Ounce for ounce birds have significantly more neurons in their brains than mammals or primates

Study gives new meaning to the term 'bird brain'
Ounce for ounce birds have significantly more neurons in their brains than mammals or primates
Vanderbilt University

The macaw has a brain the size of an unshelled walnut, while the macaque monkey has a brain about the size of a lemon. Nevertheless, the macaw has more neurons in its forebrain - the portion of the brain associated with intelligent behavior - than the macaque.

That is one of the surprising results of the first study to systematically measure the number of neurons in the brains of more than two dozen species of birds ranging in size from the tiny zebra finch to the six-foot-tall emu, which found that they consistently have more neurons packed into their small brains than are stuffed into mammalian or even primate brains of the same mass.

•••••

The study provides a straightforward answer to a puzzle that comparative neuroanatomists have been wrestling with for more than a decade: how can birds with their small brains perform complicated cognitive behaviors?

The conundrum was created by a series of studies beginning in the previous decade that directly compared the cognitive abilities of parrots and crows with those of primates. The studies found that the birds could manufacture and use tools, use insight to solve problems, make inferences about cause-effect relationships, recognize themselves in a mirror and plan for future needs, among other cognitive skills previously considered the exclusive domain of primates.

•••••

"We found that birds, especially songbirds and parrots, have surprisingly large numbers of neurons in their pallium: the part of the brain that corresponds to the cerebral cortex, which supports higher cognition functions such as planning for the future or finding patterns. That explains why they exhibit levels of cognition at least as complex as primates," said Herculano-Houzel, who recently joined the Vanderbilt psychology department.

That is possible because the neurons in avian brains are much smaller and more densely packed than those in mammalian brains, the study found. Parrot and songbird brains, for example, contain about twice as many neurons as primate brains of the same mass and two to four times as many neurons as equivalent rodent brains.

Not only are neurons packed into the brains of parrots and crows at a much higher density than in primate brains, but the proportion of neurons in the forebrain is also significantly higher, the study found.

"In designing brains, nature has two parameters it can play with: the size and number of neurons and the distribution of neurons across different brain centers," said Herculano-Houzel, "and in birds we find that nature has used both of them."

University of Oxford

A species of tropical fish has been shown to be able to distinguish between human faces. It is the first time fish have demonstrated this ability.

The research, carried out by a team of scientists from the University of Oxford (UK) and the University of Queensland (Australia), found that archerfish were able to learn and recognize faces with a high degree of accuracy -- an impressive feat, given this task requires sophisticated visual recognition capabilities.
