PHILADELPHIA - Rhythmic expression of key genes is essential for maintaining proper timekeeping of the body's clock. In addition, rhythmic degradation of clockwork proteins is also crucial. However, surprisingly, researchers know little about these specific processes.

MANHATTAN, Kansas -- Kansas State University wheat scientists have completed the first study of a chromosome in a tertiary gene pool and have called it a breakthrough in exploring wheat wild relatives for future crop improvement.
Their study, "Exploring the tertiary gene pool of bread wheat: sequence assembly and analysis of chromosome 5M of Aegilops geniculata," was published Sept. 27 in The Plant Journal.
Dengue is a mosquito-borne tropical disease currently endemic in more than 10 countries. According to the World Health Organization, 390 million people are infected by dengue every year.
Scientists from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) have found a species of coral living in a dynamic reef system, which is able to protect itself from the impact of ocean acidification.
Ocean acidification, caused by rising CO2, is one of the greatest long-term challenges facing reefs. It reduces coral's ability to form their skeletons and build reef structures.
MELBOURNE, TUESDAY 6 OCTOBER 2015: Challenging a universally accepted, longstanding consensus in the field of immunity requires hard evidence. New research from the Australian Research Council Centre of Excellence in advanced Molecular imaging has shown the proof is in the picture. And this proof may have implications for type 1 diabetes.
As the push for tinier and faster electronics continues, a new finding by University of British Columbia scientists could help inform the design of the next generation of cheaper, more efficient devices.
The work, published this week in Nature Communications, details how electronic properties at the edges of organic molecular systems differ from the rest of the material.
Dopamine deficiency in the basal ganglia (a set of subcortical structures) causes severe motor dysfunctions, such as slowness of movements (bradykinesia), as observed in Parkinson's disease. Dopamine binds D1 and D2 receptors that are expressed in the nerve cells of the striatum (a structure of the basal ganglia), and exerts different effects on the nerve cells. However, how dopamine controls through these receptors the information flow in the basal ganglia and voluntary movements is still not clear.
A common weight-loss operation called sleeve gastrectomy can make testosterone levels normal in obese men, according to new findings presented at the 2015 Clinical Congress of the American College of Surgeons. Surgeons from Stanford University in California reported that after undergoing this bariatric surgical procedure, obese patients with low testosterone levels experienced a measureable increase in their testosterone levels over a 12 month-period following the operation.
RIVERSIDE, Calif. - A decade ago, a clinical trial of human papillomavirus (HPV) vaccine in brothel-based female sex workers took Brandon Brown of the University of California, Riverside to Peru, a country where HIV prevalence is high, the epidemic concentrated in men who have sex with men (MSM).
Rats exposed to frequent physical, social, and predatory stress during adolescence solved problems and foraged more efficiently under high-threat conditions in adulthood compared with rats that developed without stress, according to Penn State researchers. The results may provide insights into how humans respond to adolescent stress.
DURHAM, N.C. -- Scientists estimate that we are losing species at 1,000-times the natural background rate.
While new technologies are improving conservation efforts by making it easier, faster and cheaper to monitor threatened species, these technologies alone cannot conserve biodiversity, a new multi-institutional study finds.
It's the most common cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), but until now scientists weren't sure how a specific gene caused these devastating diseases. Now researchers from the University of Toronto are one step closer to solving this incredibly complex puzzle, offering hope for treatment.
A team of scientists led by Dr Pierre-Marc Delaux at John Innes Centre / University of Wisconsin, Madison has solved a long-running mystery about the first stages of plant life on earth.
The team of scientists from the John Innes Centre, the University of Wisconsin - Madison and other international collaborators, has discovered how an ancient alga was able to inhabit land, before it went on to evolve into the world's first plant and colonise the earth.
Researchershave developed a novel mouse model for the vision disorder Leber hereditary optic neuropathy (LHON), and found that they can use gene therapy to improve visual function in the mice. LHON is one of many diseases tied to gene mutations that damage the tiny energy factories that power our cells, called mitochondria.
An international research team led by the University of Pittsburgh Graduate School of Public Health has shown that epidemics of dengue, which is caused by a mosquito-borne virus, across southeast Asia appear to be linked to the abnormally high temperatures brought by the El Niño weather phenomenon.
