How placentas evolved in mammals
The fossil record tells us about ancient life through the preserved remains of body parts like bones, teeth and turtle shells. But how to study the history of soft tissues and organs, which can decay quickly, leaving little evidence behind? In a new study, scientists use gene expression patterns, called transcriptomics, to investigate the ancient origins of one organ: the placenta, which is vital to pregnancy. mehr ...

'Quake brain' effects suffered by resilient Cantabrians fade over time
New research suggests the brain function of otherwise-healthy individuals exposed to event trauma has the ability to 'bounce back' over time once the threat resolves. Researchers conducted a follow-up study on a group of Cantabrians, who had been exposed to trauma during the region's earthquakes over a decade ago. mehr ...

Ice Age wolf DNA reveals dogs trace ancestry to two separate wolf populations
An international group of geneticists and archaeologists have found that the ancestry of dogs can be traced to at least two populations of ancient wolves. The work moves us a step closer to uncovering the mystery of where dogs underwent domestication, one of the biggest unanswered questions about human prehistory. mehr ...

Exercise-induced central fatigue -- low oxygen supply clouds judgment
Research on the effects of exercise in low-oxygen environments on the brain demonstrated that cognitive performance worsens when lower-than-usual amounts of oxygen are carried by the blood. Consequently, tissue in brain regions with less critical functions may receive inadequate oxygen supply to maintain normal activity levels. mehr ...

New kangaroo described -- from Papua New Guinea
Australian palaeontologists have described a new genus of giant fossil kangaroo from the mountains of central Papua New Guinea. The new description of the fossil kangaroo has found that, rather than being closely related to Australian kangaroos, it most likely belongs to a unique genus of more primitive kangaroo found only in PNG. mehr ...

When more is more: Identifying cognitive impairments with multiple drawing tasks
Researchers have found that extracting drawing features from a combination of five drawing tasks -- rather than from any single task alone -- leads to more accurate classification of people with normal cognition, mild cognitive impairment, and Alzheimer's disease by capturing different, complementary aspects of cognitive impairments. Their proposed portable, easy-to-use screening test may improve patient diagnosis, leading to earlier and more effective treatments. mehr ...

Common antiretroviral drug improves cognition in mouse model of Down syndrome
Lamivudine, a commonly-used antiretroviral drug for treating HIV, improves cognition in a mouse model of Down syndrome, according to the findings of a new study. Though clinical studies are necessary to confirm that the drug elicits a similar effect in humans, the findings pave the way for pharmacological treatments that rescue the relatively rapid cognitive decline in people with Down syndrome that is more commonly seen in much older adults in the general population. mehr ...

Researchers uncover brain waves related to social behavior
Researchers have discovered electrical brain-wave patterns given off during social interactions in mice. They also observed that mice showing signs of stress, depression, or autism lacked these brain waves. The results reveal more about the mechanics underlying brain activity when socializing. mehr ...

Supernumerary virtual robotic arms can feel like part of our body
Researchers have developed a virtual robotic limb system which can be operated by users' feet in a virtual environment as extra, or supernumerary, limbs. After training, users reported feeling like the virtual robotic arms had become part of their own body. This study focused on the perceptual changes of the participants, understanding of which can contribute to designing real physical robotic supernumerary limb systems that people can use naturally and freely just like our own bodies. mehr ...

The heat is on: Traces of fire uncovered dating back at least 800,000 years
Scientists reveal an advanced, innovative method that they have developed and used to detect nonvisual traces of fire dating back at least 800,000 years -- one of the earliest known pieces of evidence for the use of fire. The newly developed technique may provide a push toward a more scientific, data-driven type of archaeology, but -- perhaps more importantly -- it could help us better understand the origins of the human story, our most basic traditions and our experimental and innovative nature. mehr ...

The octopus' brain and the human brain share the same 'jumping genes'
The neural and cognitive complexity of the octopus could originate from a molecular analogy with the human brain, according to a new study. The research shows that the same 'jumping genes' are active both in the human brain and in the brain of two species, Octopus vulgaris, the common octopus, and Octopus bimaculoides, the Californian octopus. mehr ...

A new model sheds light on how we learn motor skills
Researchers have developed a mathematical model of motor learning that reflects the motor learning process in the human brain. Their findings suggest that motor exploration -- that is, increased variability in movements -- is important when learning a new task. These results may lead to improved motor rehabilitation in patients after injury or disease. mehr ...

Many human genomes shaped by past events that caused sharp dips in the population, study finds
The genomes of many human populations show evidence of founder events, which occur when a small number of initial members start a new population, and can lead to low genetic diversity as well as increase the risk of certain genetic diseases in the new population. mehr ...
