New findings on skewed ratio of male to female babies born to Indian-born women in Canada

Wed, 04/26/2017 - 06:40
The researchers who reported last year that more male babies than expected were being born to Indian-born women living in Canada have now found the numbers are driven by women whose mother tongue is Punjabi and, to a lesser extent, Hindi.

Brain’s ability to rewire after injury can lead to long-term strains

Wed, 04/26/2017 - 06:13
Like air-traffic controllers scrambling to reconnect flights when a major hub goes down, the brain has a remarkable ability to rewire itself after suffering an injury.

Skimpy sleep followed by 'catch up' tied to worse cognition in young adults

Wed, 04/26/2017 - 06:13
Skimping on sleep, followed by "catch-up" days with long snoozes, is tied to worse cognition -- both in attention and creativity -- in young adults, in particular, those tackling major projects, Baylor University researchers have found.

Research findings shed light on brain’s ability to make split-second decisions

Wed, 04/26/2017 - 05:59
When animals hunt or forage for food, they must constantly weigh whether the chance of a meal is worth the risk of being spotted by a predator. The same conflict between cost and benefit is at the heart of many of the decisions humans make on a daily basis.

Negative emotions can inspire cancer patients, study shows

Wed, 04/26/2017 - 05:52
Feeling down is a common side effect of being diagnosed with cancer. Anxiety, guilt, and distress often come hand-in-hand with diagnosis and treatment.

Person's brain age could help identify risk of functional decline and mortality

Wed, 04/26/2017 - 05:46
Some elderly people's brains appear older than the age on their birth certificates. These people have a higher risk of developing deteriorating age-associated conditions and impairments, and even of experiencing an earlier death than expected.

Researchers use novel phage therapy to treat patient infected with multidrug-resistant bacterium

Wed, 04/26/2017 - 05:31
Scientists and physicians at University of California San Diego School of Medicine, working with colleagues at the U.S. Navy Medical Research Center - Biological Defense Research Directorate, Texas A&M University, a San Diego-based biotech and elsewhere, have successfully used an experimental therapy involving bacteriophages -- viruses that target and consume specific strains of bacteria -- to treat a patient near death from a multidrug-resistant bacterium.

Researchers identify new rare genetic variants linked to extreme longevity

Wed, 04/26/2017 - 00:39
The search for the genetic determinants of extreme longevity has been challenging, with the prevalence of centenarians (people older than 100) just one per 5,000 population in developed nations.

Enzyme treatment may prevent or reduce liver damage caused by excess alcohol consumption

Wed, 04/26/2017 - 00:35
An intestinal enzyme previously shown to keep bacterial toxins from passing from the gastrointestinal system into the bloodstream may be able to prevent or reduce the liver damage caused by excess alcohol consumption.

Caltech researchers discover brain region that judges intensity, ambiguity of facial expressions

Wed, 04/26/2017 - 00:25
Have you ever thought someone was angry at you, but it turned out you were just misreading their facial expression? Caltech researchers have now discovered that one specific region of the brain, called the amygdala, is involved in making these (sometimes inaccurate) judgments about ambiguous or intense emotions.

Study finds link between fertility treatments and pediatric tumors

Wed, 04/26/2017 - 00:17
Ben-Gurion University of the Negev researchers have found that babies born from mothers who underwent fertility treatments are at increased risk of developing many types of pediatric cancers and tumors (neoplasms).

Research shows how TET2 protein loss can open door for mutations that drive blood cancers

Wed, 04/26/2017 - 00:09
Imagine this scenario on a highway: A driver starts to make a sudden lane change but realizes his mistake and quickly veers back, too late. Other motorists have already reacted and, in some cases, collide. Meanwhile, the original motorist - the one who caused the problem - drives on.

Mental illness does not impact bariatric surgery outcomes, study finds

Wed, 04/26/2017 - 00:00
People with pre-existing mental health conditions had nearly identical results in weight loss after bariatric surgery as compared to those with no known mental health conditions.

Neurobiologists use skin stem cells to generate new microglia

Tue, 04/25/2017 - 20:10
Using human skin cells, University of California, Irvine neurobiologists and their colleagues have created a method to generate one of the principle cell types of the brain called microglia, which play a key role in preserving the function of neural networks and responding to injury and disease.

Scientists create new technique for studying how chlamydia interacts with immune system

Tue, 04/25/2017 - 20:02
Scientists at the Wellcome Trust Sanger Institute and their collaborators at the University of British Columbia have created an innovative technique for studying how chlamydia interacts with the human immune system.

Cryopreservation reagents by AMSBIO allow long-term organoid banking

Tue, 04/25/2017 - 20:01
AMSBIO reports on an independent study that evaluated the use of CELLBANKER® and STEM CELLBANKER® reagents for cryopreservation and thawing of organoids.

KU Leuven researchers grow three-dimensional cultures of uterus' inner lining in a dish

Tue, 04/25/2017 - 19:52
Scientists at KU Leuven, Belgium, have succeeded in growing three-dimensional cultures of the endometrium, the uterus' inner lining, in a dish.

Low levels of NPTX2 protein in the brain may lead to learning and memory loss in Alzheimer's disease

Tue, 04/25/2017 - 19:41
Working with human brain tissue samples and genetically engineered mice, Johns Hopkins Medicine researchers together with colleagues at the National Institutes of Health, the University of California San Diego Shiley-Marcos Alzheimer's Disease Research Center, Columbia University, and the Institute for Basic Research in Staten Island say that consequences of low levels of the protein NPTX2 in the brains of people with Alzheimer's disease (AD) may change the pattern of neural activity in ways that lead to the learning and memory loss that are hallmarks of the disease.

Return of malaria in the U.S. is costing millions, study claims

Tue, 04/25/2017 - 18:57
Malaria-related hospitalizations and deaths in the U.S. are far more common than expected, report researchers, despite transmission having been eliminated in the country back in the 1950s.

MRI-based method for predicting brain age could help identify people at risk of early death

Tue, 04/25/2017 - 18:54
A method for predicting someone's 'brain age' based on MRI scans could help to spot who might be at increased risk of poor health and even dying at a younger age.
