Baby chicks do basic arithmetic
By Victoria Gill Science reporter, BBC News
Baby birds can do arithmetic, say researchers in Italy.
Scientists from the universities of Padova and Trento demonstrated chicks' ability to add and subtract objects as they were moved behind two screens.
Lucia Regolin, an author of the study said the animals "performed basic arithmetic" to work out which screen concealed the larger group of objects.
The findings are reported in the journal Proceedings of the Royal Society B.
Chicks always try to stay close to objects they are reared with - just as they stay close to and follow their mother as soon as they hatch. This instant recognition is known as "imprinting".
"We had already found that the chicks have a tendency to approach a group containing more of these familiar objects," explained Professor Regolin, who studies animal behaviour at the University of Padova.
She and her team were able to test the birds' numerical skills as they followed the objects - which, in this instance, were small plastic balls.
"We used the little plastic containers you get inside Kinder eggs and suspended them from fishing line," Professor Regolin told BBC News.
"We made these balls 'disappear' by moving them behind the screens one at a time."
Counting chickens
In each of the mini maths tests, a chick watched from a clear-fronted holding box while one of the researchers slowly moved the balls behind the screens - three behind one screen and two behind the other.
The front door of the box was then opened, releasing the chick into the tiny arena, so it could walk around and select a screen to look behind.
"The chicks still approached the larger of the two groups first, even though they had to rely on memory to work out which screen to choose," said Professor Regolin.
Swapping the objects from one screen to another didn't fool the maths-performing chicks.
"In a further experiment, once we had hidden the balls behind each screen, we transferred some of them from one to the other," Professor Regolin explained.
The birds, she said, were able to "count" the balls that were moved to work out which screen hid the larger set at the end of the transfer.
"They still chose correctly - adding up the numbers based on groups of objects they couldn't see at that moment."
It is already known that many non-human primates and monkeys can count, and even domestic dogs have been found to be capable of simple additions.
But this is the first time the ability has been seen in such young animals, and with no prior training.
No long sermons this time. What I hope you take away from this article is the fact that all animals, no matter their size or shape, have intelligence that, generally speaking, is greater than we tend to give them credit for. While animals like chickens are thought of as 'stupid' by us, we mainly come to that conclusion by comparing their intelligence to our own, which only makes us seem foolish, not to mention arrogant. My hope is that you will consider these things when you encounter animals, whether they're in the wild, or on the dinner table.
Fannie, Freddie worker bonuses total $210MThe article goes on with more of the same, but here's the kicker: as my eyes drifted to the right side of the screen, there in a small box titled "Top Stories" was this little gem:
WASHINGTON – Mortgage finance giants Fannie Mae and Freddie Mac plan to pay more than $210 million in bonuses through next year to give workers the incentive to stay in their jobs at the government-controlled companies.
Unemployment soars to 8.5 percent; 13M now joblessI don't even need to go on and on about this, because I have to think we're all on the same page on this one, right? And I realize that not every employee at Freddie and Fannie are responsible for this meltdown we're having, but seriously, if some of them want to leave their jobs, why not let them? Why shouldn't they have to suck it up a little bit like the rest of us?
By Ben Hirschler – Thu Apr 2, 2:30 pm ETOnce they task these robots with saving the planet, the first thing they'll do is get rid of us, and for good reason. This is going to be one interesting war...
LONDON (Reuters) – Watch out scientists – you may be replaced by a robot.
Two teams of researchers said on Thursday they had created machines that could reason, formulate theories and discover scientific knowledge on their own, marking a major advance in the field of artificial intelligence.
Such robo-scientists could be put to work unraveling complex biological systems, designing new drugs, modeling the world's climate or understanding the cosmos.
For the moment, though, they are performing more humble tasks.
At Aberystwyth University in Wales, Ross King and colleagues have created a robot called Adam that can not only carry out experiments on yeast metabolism but also reason about the results and plan the next experiment.
It is the world's first example of a machine that has made an independent scientific discovery – in this case, new facts about the genetic make-up of baker's yeast.
"On its own it can think of hypotheses and then do the experiments, and we've checked that it's got the results correct," King said in an interview.
"People have been working on this since the 1960s. When we first sent robots to Mars, they really dreamt of the robots doing their own experiments on Mars. After 40 or 50 years, we've now got the capability to do that."
Their next robot, Eve, will have much more brain power and will be put to work searching for new medicines.
King hopes the application of intelligent robotic thinking to the process of sifting tens of thousands of compounds for potential new drugs will be particularly valuable in the hunt for treatments for neglected tropical diseases like malaria.
King published his findings in the journal Science, alongside a second paper from Hod Lipson and Michael Schmidt of Cornell University in New York, who have developed a computer program capable of working out the fundamental physical laws behind a swinging double pendulum.
Just by crunching the numbers – and without any prior instruction in physics – the Cornell machine was able to decipher Isaac Newton's laws of motion and other properties.
Lipson does not think robots will make scientists obsolete any day soon, but believes they could take over much of the routine work in research laboratories.
"One of the biggest problems in science today is finding the underlying principles in areas where there are lots and lots of data," he told reporters in a conference call. "This can help in accelerating the rate at which we can discover scientific principles behind the data."

A favored method of preparing fresh crabs is to simply boil them alive. A longstanding related question: Do they feel pain?
Yes, researchers now say. Not only do crabs suffer pain, a new study found, but they retain a memory of it (assuming they aren't already dead on your dinner plate). The scientists say its time for new laws to consider the suffering of all crustaceans.
The study involved using wires to deliver shocks to the bellies of hermit crabs, which, being hermits, often take up residence in left-behind mollusc shells. The crabs that were shocked scampered out of their shells, "indicating that the experience is unpleasant for them," the scientists concluded; unshocked crabs stayed put.
Another test was run to see what would happen if a mild shock was delivered, one just below the threshold that would cause the crabs to leave home. These mildly shocked crabs, along with crabs that had not been shocked, were then offered a new home. The typical reaction: They'd go inspect the new shell. Significantly, those that had been shocked were more likely to pack up and move to the new residence compared to those that hadn't been shocked.
"There has been a long debate about whether crustaceans including crabs, prawns and lobsters feel pain," said study researcher Bob Elwood of Queen's University Belfast in the UK.
"We know from previous research that they can detect harmful stimuli and withdraw from the source of the stimuli but that could be a simple reflex without the inner 'feeling' of unpleasantness that we associate with pain," Elwood explained. "This research demonstrates that it is not a simple reflex but that crabs trade-off their need for a quality shell with the need to avoid the harmful stimulus."
The findings are detailed in the journal Animal Behaviour.
Interestingly, scientist don't fully understand pain in humans. It is felt when electrical signals are sent from nerve endings to your brain, which in turn can release painkillers called endorphins and generate physical and emotional reactions. The details remain unclear, which his why so many people suffer chronic pain with no relief.
At any rate, Elwood compared the results of the crab study to how you might react to a painful experience.
"Humans, for example, may hold on to a hot plate that contains food whereas they may drop an empty plate, showing that we take into account differing motivational requirements when responding to pain," he said. "Trade-offs of this type have not been previously demonstrated in crustaceans. The results are consistent with the idea of pain being experienced by these animals."
A Norwegian study in 2005 concluded lobsters react to boiling water or other pain stimuli, but that they don't have the emotional capacity to experience it as pain in the way higher animals do.
But a study by Elwood and colleagues in 2007 found prawns were irritated when their antennae were treated with acetic acid, and after a local anesthetic, they'd stop rubbing the antennae. He said this was evidence that they suffer pain, and that lobsters likely feel pain, too.
Elwood thinks its time for some crustacean empathy.
"Millions of crustacean are caught or reared in aquaculture for the food industry," he said. "There is no protection for these animals (with the possible exception of certain states in Australia) as the presumption is that they cannot experience pain. With vertebrates we are asked to err on the side of caution and I believe this is the approach to take with these crustaceans."

Army fired 11 soldiers in Jan. as openly gayOur country is at war, and our military is begging for more troops. So how much sense does it make to tell someone who is so supportive of you that they're willing to give their life for your cause that you don't want their help because they're gay?

WASHINGTON – The Army fired 11 soldiers in January for violating the military's policy that gay service members must keep their sexuality hidden, according to a Virginia congressman.
Democratic Rep. Jim Moran said he has requested monthly updates from the Pentagon on the impact of the policy until it is repealed. In a statement released on Thursday, Moran said the discharged soldiers included an intelligence collector, a military police officer, four infantry personnel, a health care specialist, a motor-transport operator and a water-treatment specialist.
"How many more good soldiers are we willing to lose due to a bad policy that makes us less safe and secure?" asked Moran, a member of the House panel that oversees military spending.
The Pentagon's "don't ask, don't tell" policy was instituted after President Bill Clinton tried to lift the ban on gay service members in 1993. It refers to the military practice of not asking recruits their sexual orientation. In turn, service members are banned from saying they are gay or bisexual, engaging in homosexual activity or trying to marry a member of the same sex.
The military discharged nearly 10,000 service members under the policy in a 10-year period, from 1997 to 2007. The number fired each year dropped sharply after the 2001 invasion of Afghanistan, when forces were stretched thin. Whereas more than 1,200 were dismissed in 2000 and 2001 for violating the policy, about half as many — 627 — were fired in 2007.
The Pentagon has not released its 2008 figures.
The White House has said President Barack Obama has begun consulting with Defense Secretary Robert Gates and Chairman of the Joint Chiefs of Staff Adm. Michael Mullen on how to lift the ban. But the administration won't say how soon that might happen or whether a group of experts will be commissioned to study the issue in-depth, as some Democrats have suggested.
Likewise, Democratic leaders on Capitol Hill support repealing the ban but have not promised to press the issue immediately.

The story behind this photo:
The summer 2008 I met a little fox in the woods.....
I went out to photograph flowers...I was in the middle of the forest among the pine needles and leaves and flowers...and mosquitoes...the sun was coming down...it was a little chilly...
"Bang!"...what was that...? "Bang!"...again...it was branches and cones, which fell down from the trees...I thought it sounded like hoof steps...
"Cough!?...?Sneezy!?...What was this? I turned around ... and find to my surprise, a little red fox...it was coughing...maby either it was cold, or allergic..;)
?Typical...?...I thought...?I don`t have my zoom lens with me...?
I started to approach the little fox slowly...slowly...slowly...it jumped all around...back and forth ...back and forth...
Finally...after maybe fifteen minutes, he sat down...
I approached slowly...no sudden movements... slowly...
There I was...in front of the little fox...eye to eye, for maybe a half hour...one meter from it, with my Tamron 90 mm...without a tripod...in bad light...mosquitoes all over.....
Each time the sharpness locked on the camera and it clicked...the little fox leaned his head...:))
There he was...so small and cute...so sweet and red.....:)
Tom’s Story: A Gentle Giant
With gray hair, a freckled face, and a large body, Tom is a likeable fellow. His caregivers describe him as a gentle giant, and say that he is likely to remind you of a dear old uncle.
Born in Africa, Tom was ripped from his family and spent 30 years in labs where he was infected with HIV. He endured over 369 knockdowns, 56 punch liver biopsies, one open liver wedge biopsy, and three lymph node and three bone marrow biopsies. In the lab, Tom was plagued by intestinal parasites, and often had diarrhea and no appetite. When he had strength, he banged constantly on his cage.
Today, Tom lives at Fauna Foundation, but is limited in the social skills necessary to be a part of a group - skills he would have learned from his mother and family in Africa. Instead, he lived alone in barren laboratory cages with little opportunity to be a real chimpanzee among his own kind. However, Tom’s social skills have greatly improved, and he spends time during his days with one or two chimpanzee friends at a time, including Jethro.

CANBERRA (Reuters) – A love story between two badly burned koalas rescued from Australia's deadliest bushfires has provided some heart-warming relief after days of devastation and the loss of over 180 lives.
The story of Sam and her new boyfriend Bob emerged after volunteer firefighter Dave Tree used a mobile phone to film the rescue of the bewildered female found cowering in a burned out forest at Mirboo North, 150 km (90 miles) southeast of Melbourne.
Photos and a video of Tree, 44, approaching Sam while talking gently to her, and feeding her water from a plastic bottle as she put her burned claw in his cold, wet hand quickly hit video sharing website YouTube (www.youtube.com/watch?v=-XSPx7S4jr4), making her an Internet sensation.
But it was after reaching a wildlife shelter that Sam met and befriended Bob, who was saved by wildlife workers on Friday, two days before Sam, in Boolarra, about 180 km from Melbourne.
Tree, who has been a volunteer firefighter for 26 years, said it was extremely rare to get so close to a koala so he asked his colleague Brayden Groen, 20, to film him.
"You can how she stops and moves forward and looks at me. It was like a look saying "I can't run, I'm weak and sore, put me out of my misery,"" Tree told Reuters.
"I yelled out for some water and I sat down with her and tipped the water up. It was in my hand and she reached for the bottle then put her right claw into my left hand which was cold so it must have given her some pain relief and she just left it there. It was just amazing."
INSPIRING LOVE STORY
Sam was taken to the Southern Ash Wildlife Shelter in Rawson. Her story was reminiscent of a koala named Lucky who survived the 2003 bushfires that destroyed about 500 homes and killed four people in the capital of Canberra. Lucky became a symbol of hope.
Colleen Wood from the Southern Ash Wildlife Shelter that is caring for Sam and Bob said both koalas were doing well while other animals like possums, kangaroos, and wallabies were also starting to emerge from the debris.
She said Sam had suffered second degree burns to her paws and would take seven to eight months to recover while Bob had three burned paws with third degree burns and should be well enough to return to the bush in about four months.
"They keep putting their arms around each other and giving each other hugs. They really have made friends and it is quite beautiful to see after all this. It's been horrific," said Wood.
"Sam is probably aged between two to four going by her teeth and Bob is about four so they have a muchness with each other."
Wood said about 20 koalas had been brought into her shelter in recent days, several of whom had bonded as koalas are known to clump together, but none had garnered the same attention as the new Internet star Sam.
Tree, a volunteer with the Country Fire Authority Victoria, has visited Sam since her rescue and was delighted to see she had found a boyfriend in Bob.
"They've really taken a shine to each other as they are both burned and share the same burned smell," he said.
"My heart goes out to the people in these fires and this was so innocent so people have used this to distract them from all the sad stuff that has gone on. It gives people a bit of hope."
