Adalatherium is an important piece in a very large puzzle on early mammalian evolution in the southern hemisphere, one in which most of the other pieces are still missing
In recent years, the number of high-risk groups for ischemic diseases such as critical limb ischemia where tissues of toe may decay is increasing due to increase in the number of people with obesity, diabetes, and hypertension which are triggered by changes in dietary habits, and consumption of smoking and alcohol. A number of studies are actively conducted on endothelial progenitor cells (hEPCs), which are stem cells that contribute to the blood vessel regeneration in the ischemic tissues, to treat such ischemia diseases.
Mathematicians have used machine learning to develop a new model for measuring poverty in different countries that junks old notions of a fixed 'poverty line'.
The study by academics at Aston University, published in the journal Nature Communications, suggests mainstream thinking around poverty is outdated because it places too much emphasis on subjective notions of basic needs and fails to capture the full complexity of how people use their incomes.
The Christmas season is associated with preventable harms from cards, tree decorations, and presents, as well as overeating and overdrinking, so do the benefits of Christmas outweigh the harms?
In the Christmas issue of The BMJ, Robin Ferner and Jeffrey Aronson dig out some cautionary tales from the archives.
Hospital clowns might help improve physical symptoms and psychological wellbeing in children and adolescents having treatment for acute or chronic conditions, finds a study in the Christmas issue of The BMJ.
The findings suggest that incorporating appropriate laughter and play into clinical practice can be beneficial for young patients who need to stay in hospital.
Previous studies have suggested that hospital clowns can help to reduce stress and anxiety in children before and after surgery, but results have been inconsistent.
As Father Christmas gears up for the busiest 24 hours of his year, what skills does he use to get a seemingly impossible job done effectively and safely - and can they be applied to medicine?
In the Christmas issue of The BMJ, two doctors reflect on the many lessons that the medical profession can learn from Father Christmas.
One in five doctors in Sweden has a parent who is also trained in medicine, more than triple the proportion for doctors born three decades earlier, finds a study in the Christmas issue of The BMJ.
The findings suggest that among doctors in Sweden, medicine might increasingly run in families.
Days when high profile European football matches are played are associated with more traffic accidents in Asia than days when less popular matches are played, finds a study in the Christmas issue of The BMJ.
One explanation may be that Asian drivers stay awake until the early hours of the morning to watch high profile football games and lose sleep as a result.
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.
