Individuals with high ADHD-traits that do not meet the criteria for a diagnosis are less able to perform tasks involving attentional regulation or emotional control after a sleepless night than individuals with low ADHD-traits, a new study from Karolinska Institutet published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging reports.

Bans on shark fishing are only partially effective in protecting sharks, new research suggests.

Scientists from the University of Exeter, international conservation charity ZSL (Zoological Society of London) and Sri Lankan NGO Oceanswell examined the effects of a blanket ban on landing thresher sharks, brought in by the Sri Lankan government in 2012.

Information gathered from local fishers suggests the ban has stopped targeted fishing for the sharks - but persistent "bycatch" (accidental catching) continues.

Researchers from The Wharton School of the University of Pennsylvania published a new paper in the Journal of Marketing that assesses the implications of the growth of private genetic testing for the field of marketing and evaluates ethical challenges that arise. The researchers review past research in the field of behavioral genetics and use these findings to incorporate genetic influences into existing consumer behavior theory.

DALLAS - Dec. 16, 2020 - A team led by UT Southwestern researchers has identified a key gene necessary for cells to consume and destroy viruses. The findings, reported online today in Nature, could lead to ways to manipulate this process to improve the immune system's ability to combat viral infections, such as those fueling the ongoing COVID-19 pandemic.

A new study has revealed paying patients are 20 per cent less likely to die or develop major complications, such as reintervention or stroke, after cardiac surgery than NHS patients - findings researchers say cannot be explained by socioeconomic factors alone.

The study, led by academics at the University of Bristol, looked at the data of over 280,000 patients who underwent adult cardiac surgery over a ten-year period from 2009 to 2018 at 31 NHS cardiac units in England. 5,967of these were private payers and 274,242 were government funded.

A female-typical language style promotes the popularity of talks in the digital context and turns out to be an underappreciated but highly effective tool for social influence. This was shown by UZH psychologists in an international study in which they analyzed 1,100 TED Talks.

Star-forming processes sometimes create mysterious astronomical objects called brown dwarfs, which are smaller and colder than stars, and can have masses and temperatures down to those of exoplanets in the most extreme cases. Just like stars, brown dwarfs often wander alone through space, but can also be seen in binary systems, where two brown dwarfs orbit one another and travel together in the galaxy.

Body odor is an unpleasant smell, produced when bacteria living on the skin break down the proteins in sweat. To avoid stinking, some people apply antiperspirants that clog sweat ducts with foreign materials, such as metals, to slow perspiration. As a step toward a more natural solution, researchers reporting in ACS Applied Materials & Interfaces have turned sweat against itself using an evaporation-based approach in which the salts in sweat create a gel-like plug.

CLEMSON, South Carolina - You must first understand how something works normally before you can figure out why it's broken.

That's the idea behind brain research by Yuqing "Iris" Hang, a Clemson University graduate student pursuing a doctorate in biochemistry in the College of Science's Department of Genetics and Biochemistry.

Hang is studying how genes interact in a normal brain.

"When studying a disease trait, we always need to compare that trait to the normal condition," she said.

A third of all babies and half of Black, Asian and Minority Ethnic (BAME) babies are vitamin D deficient, a large study of 3000 newborn's in the West Midlands has shown, highlighting potential shortfalls in the current UK antenatal supplementation programme.

Chimpanzees and bonobos are sister species that diverged around 1.8 million years ago as the Congo River formed a geographic boundary and they evolved in separate environments. Now, a whole-genome comparison of bonobos and chimpanzees reveals the gene pathways associated with the striking differences between the two species' diets, sociality and sexual behaviors.

The journal Genes, Brain and Behavior published the comparative analysis, conducted by anthropologists at Emory University.

Cancer metastasis, which is the dissemination of tumor cells into distant organs,
is the leading cause of mortality in cancer patients. To undergo metastasis, cells must
