|Eating Air, Making Fuel|
Biology » Bacterium, Coli »
Weizmann Institute of Science − All life on the planet relies, in one way or another, on a process called carbon fixation: the ability of plants, algae and certain bacteria to "pump" carbon dioxide (CO2) from the environment, add solar or other energy and turn it into the sugars that are the required starting point needed for life processes. At the top of the food chain are different organisms (some of which think, mistakenly, that they are "more advanced") that use the opposite means of survival: they eat

|Eyewitnesses Who Collaborate Make Fewer Mistakes in Police Interview|
Psychology » Witnesses, Eyewitness »
Vrije Universiteit Amsterdam − Witnesses correct each other's errors. Two recently published research studies by legal psychologists Annelies Vredeveldt and Peter van Koppen at Vrije Universiteit Amsterdam show that witnesses make fewer errors when they are interviewed together than when they are interviewed separately. This stands in sharp contrast with current police guidelines to always interview witnesses separately.
|Not Only Trauma but Also the Reversal of Trauma Is Inherited|
Medicine » Childhood, Children »
University of Zurich − Traumatic experiences in childhood increase the risk of developing behavioral and psychiatric disorders later in life. It is also known that the consequences of a trauma can likewise be observed in the children of people affected even if those children have themselves not experienced any trauma. However, childhood trauma in some conditions can also help individuals deal better with difficult situations later in life. This ability, too, is passed onto following generations. These findings have recently been uncovered by Isabelle Mansuy, Professor of

|How Well Do Facial Recognition Algorithms Cope with a Million Strangers?|
Technology » Face, Recognition »
University of Washington − In the last few years, several groups have announced that their facial recognition systems have achieved near-perfect accuracy rates, performing better than humans at picking the same face out of the crowd. But those tests were performed on a dataset with only 13,000 images -- fewer people than attend an average professional U.S. soccer game. What happens to their performance as those crowds grow to the size of a major U.S. city?
|Female Blue Tits Sing in the Face of Danger|
Biology » Decoys, Males »
University of Veterinary Medicine -- Vienna − Until now, the singing behaviour of songbirds had been mainly associated with competitive behaviour and the search for a partner. Moreover, males had long been considered to be the more active singer. Females were compared to the behaviour of the males and were seen as relatively "lazy" with regard to singing.
|New Research Uncovers Why an Increase in Probability Feels Riskier Than a Decrease|
Psychology » Change, Bullies »
University of Toronto − Probability estimates are constantly changing. A 20 per cent chance of rain suddenly goes to 30 per cent and we start thinking about packing an umbrella. But how differently do we react when a forecast goes from a 40 per cent chance of rain down to 30? According to a new U of T study, the probability of something happening can feel more or less likely to happen depending on an upward or downward change in an estimate.
