Probes shed new light on Alzheimer's cause
Researchers have found a way to track the formation of soluble amyloid beta peptide aggregates in lab samples. The aggregates are implicated in the onset of Alzheimer's disease.

Better samples, better science: New study explores integrity of research specimens
Biological samples can be highly susceptible to changes over time, which often occur when they are removed from deep refrigeration. Degraded samples can produce spurious results in research. To address these concerns, scientists have designed a highly sensitive test that can be used to establish the integrity of blood plasma and serum, the most common biosamples used in medical research.
Read moreNew study on sharing shows social norms play a role in decision making
A child's desire to share becomes influenced by social norms around the age of 8, new research has revealed. The extensive study — conducted on eight diverse societies across the world — examined children and adults' behavior when asked to respond to a set of specific sharing tasks.
Read moreEmpowering cancer patients to shift their mindsets could improve care, researchers argue
A cancer diagnosis can cause a significant emotional burden for patients and their families. This may persist years into survivorship. As a result, depression and anxiety are two to three times more common in cancer patients than the general population. Experts propose that targeting cancer patients' mindsets could have an impact on their health, functioning, and well-being, and they call for more research in this field.

Scientists have discovered that a natural antioxidant commonly found in green tea can help eliminate antibiotic resistant bacteria.
Read moreNew reaction will make indoline scaffolds available for pharmaceutical development
New approach to producing indolent scaffolds could streamline development and production of small-molecule pharmaceuticals, which comprise the majority of medicines in use today.
Read moreDo the costs of cancer drugs receive enough attention?
A recent analysis from Canada found that information on health-related quality of life is often not collected for investigational cancer drugs or used to calculate the balance of costs and benefits of these drugs when they are submitted for reimbursement.

In people with diabetes, fat mass index, not body mass index (BMI), is associated with a higher risk of cardiovascular events, according to new research.
Read moreDNA is held together by hydrophobic forces
Researchers have disproved the prevailing theory of how DNA binds itself. It is not, as is generally believed, hydrogen bonds which bind together the 2 sides of the DNA structure. Instead, water is the key. The discovery opens doors for new understanding in research in medicine and life sciences.
Read moreUS pediatric heart transplant waitlist policy change falls short of intended benefits
In March 2016, the Organ Procurement and Transplantation Network revised its criteria for prioritizing children awaiting heart transplantation in the US with the intention of reducing the number of deaths on the waitlist, but a new study suggests unintended consequences.
