Bean plants that suppress secondary root growth in favor of boosting primary root growth forage greater soil volume to acquire phosphorus, according to Penn State researchers, who say their recent findings have implications for plant breeders and improving crop productivity in nutrient-poor soils.
Traumatic brain injuries, whether suffered from a blow on the football field or the battle field, can be devastating, leading to disability and shortened lives. However, little is known about how different levels of injury and time affect the brain, hindering efforts to develop effective treatments. Scientists now report results from rodent studies in ACS' Journal of Proteome Research showing that signaling molecules are likely involved in mild cases, also known as concussions.
It's often said that creative people see the world differently than the rest of us - and a Harvard researcher is providing one answer why.
Babies often amaze their parents when they seemingly learn new skills overnight -- how to walk, for example. But their brains were probably prepping for those tasks long before their first steps occurred, according to researchers.
Researchers at Penn State are using new statistical analysis methods to compare how we observe infants develop new skills with the unseen changes in electrical activity in the brain, or electroencephalography (EEG) power. They found that most babies appear to learn new skills in irregular bursts, while their EEG power grows steadily behind the scenes.
Researchers at Oregon State University (OSU) are giving an ancient grain a new life: this barley is naked, but not in an indecent way.
Most barley grains are covered rather than naked. Covered varieties have a hull--or outer layer--firmly attached to the grain. The hull on 'Buck'--as in "Buck-naked"--doesn't hang on to the grain. Instead, the hulls fall off during harvest.
"Even barley geneticists try to have a sense of humor," said Patrick Hayes, crop scientist. Hayes is part of the OSU Barley Project, a team of barley enthusiasts and breeders.
Amsterdam, Netherlands, 17th January 2018 - A new peer-reviewed clinical trial to be published in the February edition of Regulatory Toxicology and Pharmacology shows that regular use of e-cigarettes does not have any negative health impact on smokers.
Using 'next generation' DNA sequencing scientists have found that the famous 'Two Brothers' mummies of the Manchester Museum have different fathers so are, in fact, half-brothers.
The Two Brothers are the Museum's oldest mummies and amongst the best-known human remains in its Egyptology collection. They are the mummies of two elite men - Khnum-nakht and Nakht-ankh - dating to around 1800 BC.
How does the honeybee manage to visit the flowers that bloom exactly at the right time? How do bees find their way back to the hive even when the sun, which they use as reference point, has changed its position in the sky? How do they communicate this information to other bees? And which molecular processes control this behaviour and in which anatomical structures do they take place?
Children who experience abuse and neglect early in life are more likely to have problems in social relationships and underachieve academically as adults.
Maltreatment experienced before age 5 can have negative effects that continue to be seen nearly three decades later, according to a new study led by Lee Raby, an assistant professor of psychology at the University of Utah.
Philadelphia, January 16, 2018 - Young people with cannabis dependence have altered brain function that may be the source of emotional disturbances and increased psychosis risk that are associated with cannabis abuse, according to a new study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. The alterations were most pronounced in people who started using cannabis at a young age.
