Finding the answers hidden in our antibodies

An innovative protocol called PepSeq is changing the way researchers test for contagious diseases -- and this knowledge should change the way humanity responds to future pandemics. Researchers just published a comprehensive study about PepSeq that lays out the process, the tool and how to interpret the results, with the goal of more, better and faster information for the next outbreak.

Simulated driving program reduces crash risk for teens with ADHD in small study

A program that combines computer-based and driving simulator training may reduce the proportion of crashes and near crashes among teens with attention-deficit/hyperactivity disorder (ADHD), according to a small study. Teens who took the training, which aims to reduce the number of long glances away from the roadway, had a nearly 40% lower risk for crash or near crash, compared to a similar group...

Male orb-weaving spiders fight less in female-dominated colonies

Orb-weaving spiders cooperate for more peaceful colonies, a surprising revelation given that most spiders live solitarily. In the colonies that researchers observed, male spiders fought less with one another when there were more female spiders in a colony. But colonies with large numbers of larger and medium-sized female spiders tended to have more aggressive environments.

Single-cell 'atlas' reveals origin of an aggressive brain tumor

Data from a new fetal brain atlas has helped a science team discover a collection of progenitor cells that give rise to aggressive 'group 3' medulloblastomas. Findings include identifying two genes that may serve as treatment targets. Mice with these tumors lived longer when bred to express reduced activity of these genes.

New data set improves modeling of supersonic flows around a cantilever

Extreme pressures come with high-speed flight. The resulting aerodynamic forces can bring significant risk to deforming the components of the vehicle in motion -- even to the point of aeroelastic deformation -- when solids behave more like liquids. This can jeopardize stability or controllability of the entire vehicle.

Potential genetic variants linked to increased cancer risk in children with birth defects

Researchers have identified several genetic variants associated with increased risk of cancer in children with non-chromosomal birth defects, such as congenital heart disease and defects of the central nervous system. While the risk of developing cancer is not as high as children with chromosomal birth defects, it is significantly higher than children with no birth defects at all, and the findings...

Scientists uncover novel DNA repair mechanism for key cancer target

Scientists have identified how an enzyme involved in DNA repair (POLQ), becomes vital to the survival of certain cancers, if the cancer cells lose the ability to use a more common method of DNA repair. The work uncovers an unappreciated role for POLQ in responding to DNA replication stress, providing the scientific underpinnings for a Phase I clinical trial evaluating the effects of blocking this...
