Latest coronavirus research reveals important differences between new virus and SARS
New research published in The Lancet Infectious Diseases provides the first complete viral load profile-- a comprehensive clinical description of where and how much of the virus circulates through the body-- of a patient infected with Middle East respiratory syndrome coronavirus.

Noble gases hitch a ride on hydrous minerals
The six noble gases do not normally dissolve into minerals, leaving earth scientists to wonder how they are recycled back into the Earth.

Short-term antidepressant use, stress, high-fat diet linked to long-term weight gain
Short-term use of antidepressants, combined with stress and a high-fat diet, is associated with long-term increases in body weight, a new animal study finds.

Drug boosts fat tissue's calorie-burning ability in lab
A drug that mimics the activity of thyroid hormone significantly increases the amount of energy burned by fat tissue and promotes weight loss, an animal study of metabolism finds.

Skipping breakfast may make obese women insulin resistant
Overweight women who skip breakfast experience acute, or rapid-onset, insulin resistance, a condition that, when chronic, is a risk factor for diabetes, a new study finds.

Father's diet before conception affects offspring's body fat in mice
When fathers eat a high-fat diet before conception of offspring, the male offspring have increased body weight after weaning and high body fat in midlife despite eating a low-fat diet, a new study in mice finds.

Global cooling as significant as global warming
International study confirms the link between global cooling and a crash in the marine ecosystem similar to that witnessed as a result of global warming.

HIV prevention among female sex workers in India reduces HIV and syphilis
HIV prevention programs for female sex workers in India reduce rates of syphilis, HIV and other sexually transmitted infections, a University of Toronto study has found.

IU chemists produce star-shaped macromolecule that grabs large anions
Chemists at Indiana University Bloomington have created a symmetrical, five-sided macrocycle that is easy to synthesize and has characteristics that may help expand the molecular tool box available to researchers in biology, chemistry and materials sciences.

Advances in genetic sequencing diagnose Paralympic hopeful's rare condition
National Paracycling Champion Tom Staniford has an extremely rare condition which, until now, has puzzled his doctors.

Obese male mice father offspring with higher levels of body fat
Male mice who were fed a high-fat diet and became obese were more likely to father offspring who also had higher levels of body fat, a new Ohio University study finds.

Testosterone therapy improves sexual function after uterus and ovary removal
High doses of testosterone significantly improve sexual function among women who have had their uterus and ovaries surgically removed, a clinical study demonstrates.

Insulin resistance linked to weaker bones
Reduced effectiveness of the hormone insulin, or insulin resistance, is associated with weakened bones, a clinical study shows.

'Chase and run' cell movement mechanism explains process of metastasis
A mechanism that cells use to group together and move around the body -- called 'chase and run' -- has been described for the first time by scientists at UCL.

Mapping translation sites in the human genome
John Chaput and his colleagues at Arizona State University's Biodesign Institute have produced the first genome-wide investigation of cap-independent translation, identifying thousands of mRNA sequences that act as Translation Enhancing Elements, which are RNA sequences upstream of the coding region that help recruit the ribosome to the translation start site.

The Rett Syndrome protein surrenders some of its secrets
Discovery of a mutant gene responsible for a disease is a milestone, but for most conditions, it may be only a first step towards a treatment or cure.
