Scientists seek genetic causes of condition that can result in absent uterus and vagina

EurekAlert! Biology - 1 hour 49 min ago
(Medical College of Georgia at Augusta University) A percentage of females are born with a missing or underdeveloped vagina and uterus, and scientists are working to analyze the genes of hundreds of them to get a better idea about causes, improve genetic counseling and ideally treatment.

Rising temperatures may safeguard crop nutrition as climate changes

EurekAlert! Biology - 1 hour 49 min ago
(Carl R. Woese Institute for Genomic Biology, University of Illinois at Urbana-Champaign) Recent research has shown that rising carbon dioxide levels will likely boost yields, but at the cost of nutrition. A new study in Plant Journal suggests that this is an incomplete picture of the complex environmental interactions that will affect crops in the future -- and rising temperatures may actually benefit nutrition but at the expense of lower yields.

Widely available food in US workplaces: Perk or hazard?

EurekAlert! Biology - 1 hour 49 min ago
(Elsevier) Nearly a quarter of employed adults obtain foods and beverages at work at least once a week, according to a new study from the US Centers for Disease Control and Prevention (CDC) and published in the Journal of the Academy of Nutrition and Dietetics. Foods obtained at work are often high in calories, refined grains, added sugars, and sodium.

Possible Oahu populations offer new hope for Hawaiian seabirds

EurekAlert! Biology - 1 hour 49 min ago
(American Ornithological Society Publications Office) The two seabird species unique to Hawaii, Newell's shearwaters and Hawaiian petrels, are the focus of major conservation efforts -- at risk from habitat degradation, invasive predators, and other threats, their populations plummeted 94 percent and 78 percent respectively between 1993 and 2013. However, a new study in The Condor: Ornithological Applications offers hope of previously undetected colonies of these birds on the island of Oahu, from which they were believed to have vanished by the late 1700s.

New study raises hopes of eradication of malaria

EurekAlert! Biology - Sun, 2019-01-20 21:00
(Karolinska Institutet) After major global successes in the battle against malaria, the positive trend stalled around 2015 -- apart from in Zanzibar in East Africa, where only a fraction of the disease remains. In a new study published in BMC Medicine, researchers at Karolinska Institutet in Sweden explain why this was and show that new strategies are needed to eradicate the disease. One of the problems is a change in mosquito behaviour and selection in the parasites.

The diversity of rural African populations extends to their microbiomes

EurekAlert! Biology - Sun, 2019-01-20 21:00
(University of Pennsylvania) In the largest study of its kind, a team led by University of Pennsylvania researchers investigated the gut microbiomes of people from seven ethnically diverse populations from remote areas of Botswana and Tanzania. Their findings illuminate the relative impact of lifestyle, geography, and genetics in shaping the microbiome.

Leaf age determines the division of labor in plant stress responses

EurekAlert! Biology - Sun, 2019-01-20 21:00
(Max Planck Institute for Plant Breeding Research) A new study from researchers at the Max Planck Institute for Plant Breeding Research published in the journal PNAS shows that the crosstalk between plant responses to physical and biological stresses varies between young and old leaves to enable optimal plant performance when the two kinds of stress are encountered simultaneously.

Fossilized slime of 100-million-year-old hagfish shakes up vertebrate family tree

EurekAlert! Biology - Sun, 2019-01-20 21:00
(University of Chicago Medical Center) Paleontologists at the University of Chicago have discovered the first detailed fossil of a hagfish, the slimy, eel-like carrion feeders of the ocean. The 100-million-year-old fossil helps answer questions about when these ancient, jawless fish branched off the evolutionary tree from the lineage that gave rise to modern-day jawed vertebrates, including bony fish and humans.

Researchers for the first time identify neurons in the human visual cortex that respond to faces

EurekAlert! Biology - Sun, 2019-01-20 21:00
(Bar-Ilan University) A new study identifies the neurons in the human visual cortex that selectively respond to faces. The researchers showed that the neurons in the visual cortex (in the vicinity of the Fusiform Face Area) responded much more strongly to faces than to city landscapes or objects. In an additional experiment, the neurons exhibited face-selectivity to human and animal faces that appeared within a movie. The results provide unique insights into human brain functioning at the cellular level during face processing.

Mice pass on brain benefits of enriched upbringing to offspring

EurekAlert! Biology - Sun, 2019-01-20 21:00
(Society for Neuroscience) Mice growing up in a basic cage maintain lifelong visual cortex plasticity if their parents were raised in an environment that promoted social interaction and physical and mental stimulation, according to a multigenerational study published in eNeuro. The research suggests life experience may be transmitted from one generation to the next through a combination of changes in gene expression and parental caretaking behavior.

Implantable device curbs seizures and improves cognition in epileptic rats

EurekAlert! Biology - Sun, 2019-01-20 21:00
(Society for Neuroscience) A protein-secreting device implanted into the hippocampus of epileptic rats reduces seizures by 93 percent in three months, finds preclinical research published in JNeurosci. These results support ongoing development of this technology and its potential translation into a new treatment for epilepsy.
