Scientists rely on animal models to gain insight into how we learn language, but one of their favorite models, the zebra finch, has been misunderstood. New study shows finches don’t just learn their songs by imitating adults, they learn by watching their mothers’ reactions to their immature songs.


Fasting,which puts the body in starvation mode, leads to fuel substitution, antioxidation, increased mitochondrial activation and altered signal transduction. Fasting boosts metabolic activities and has a variety of health benefits.

Procrastination is not just a matter of willpower or laziness. A new brain-scan study finds that procrastination can occur due to difficulties in valuing outcomes or associating outcomes with tasks.


Scientists gave an off-the-shelf robot arm a 'self image' and watched it improve at tasks like picking things up. In a paper in Science Robotics, the researchers speculate that "this separation of self and task may have also been the evolutionary origin of self-awareness in humans.”


Here's How Much Ice Antarctica Is Losing: The world’s southernmost continent is jettisoning six times more ice now than it was four decades ago.


Scientists create a silicone skin with ferro-liquid coursing in micro tubes that could give multi-sensor ability - to sense pressure, sound, heat and vibration as well as magnetic fields, each distinguishable from the other by the characteristic effect on the ferro-fluid


Scientists at MIT have designed a hydrogel pill that swells to the size of a ping-pong ball when it reaches the stomach and is retained. It could be used to monitor tumors, ulcers or signs of bacteria or virus. It could be removed by drinking a calcium solution that shrinks it to its original size.


Judges give harsher sentences to black defendants than similar nonblack defendants, and harsher sentences to males than similar female defendants. Republican-appointed judges have greater gender and race disparities in sentencing than Democratic-appointed judges.


56-page report in "The Lancet" argues obesity, undernutrition, and climate change are a trio of interconnected global pandemics, which scientists call the "Global Syndemic." They are all driven by inequitable food systems/"Big Food."

Children who lived in areas with higher air pollution when younger are significantly more likely to have developed major depression by the age of 18, according to research


‘More unites us than divides us’ - New research based on data from over 60 countries and 140,000 people suggests that people are much more united in their beliefs and values than media reporting would suggest. This narrative may be perpetuated and seized upon by politicians to sow divisions.


Columbia Engineers Translate Brain Signals Directly into Speech. Advance marks critical step toward brain-computer interfaces that hold immense promise for those with limited or no ability to speak.


A study in Wednesday's Journal of the American Heart Association found that a larger number of babies will probably be born with congenital heart defects between 2025 and 2035 due to their mothers' exposure to higher temperatures, triggered by climate change, while pregnant.


Oversized meals have been shown to be a factor in obesity - A new study conducted in Brazil, China, Finland, Ghana, India and the United States found 94% of meals served in restaurants contain more than the recommended number of calories.


New research shows how the effects of Lupus are caused by different autoantibody immune 'rogue clones' that target specific organs and tissue. Identifying and measuring the specific components of autoantibody could lead to more targeted treatments for specific patients.
