CU, Old Dominion team finds sea level rise in western tropical Pacific anthropogenic

A new study led by Old Dominion University and the University of Colorado Boulder found sea levels are rising in the tropical Pacific off the coasts of the Philippines and northeastern Australia. The research team estimated that areas near these regions are being raised by about 1 centimeter per year due to anthropogenic warming.

Study examines rate of HIV diagnosis in US

The annual HIV diagnosis rate in the US decreased by 33.2% from 2002 to 2011, driven by declines in several key populations, including women and persons aged 35-44 years. Despite increases among young men who have sex with men, overall diagnoses attributed to injection drug use or heterosexual contact decreased.

Hepatitis C cured in co-infected HIV patients

A phase III clinical trial shows that a combination drug therapy cures chronic hepatitis C in the majority of patients co-infected with both HIV and hepatitis C. The new all-oral regimen sofosbuvir and ribavirin has cure rates of up to 92% for treatment-experienced patients, offering a transformative step in treating this population.

A new measure of biodiversity

Scientists applied a new method to Australia's Acacia genus, revealing biologically important but currently unprotected areas. The study confirmed the Wet Tropics rainforests' importance and identified places of 'super-endemism', where old and new species co-exist.

Scientists find new clues to brain's wiring

Researchers at Washington University School of Medicine have identified a group of proteins that program common type of brain nerve cell to connect with another type of nerve cell. This finding is an important step forward in understanding the causes of intellectual disability and autism by learning how developing brain is built.

UM-led research team contributes to the management of South Florida coastal environments

A collaborative research team published findings in Ecological Indicators on a new marine ecosystem support tool to improve decision-making by natural resource managers. The MARES project integrates ecosystem science and societal benefits into a management framework, providing exportable technology for other coastal ecosystems.

Autophagy protects insulin-secreting cells of the pancreas

Researchers found that a functional autophagy system prevents the accumulation of toxic islet amyloid polypeptide, which can lead to diabetes. In animal models, autophagy-deficient beta cells developed overt diabetes, highlighting the protective role of autophagy in pancreatic beta cell function.

New trigger for ovulation could make IVF safer

Researchers have successfully used kisspeptin to stimulate ovulation in women undergoing IVF treatment, reducing the risk of OHSS. Twelve babies were born after their mothers received the hormone injection, with 12 becoming pregnant and nine having healthy embryos transferred.

Highly charged ions

A new theoretical study by Marianna Safronova and colleagues identifies 10 highly charged ions, including samarium-14+ and neodymium-10+, suitable for atomic timekeeping and quantum information schemes. The researchers provide estimates of ion properties needed for experiments, enabling the development of more accurate clocks and qubits.

Feinstein Institute researchers identify brain network

Researchers at The Feinstein Institute for Medical Research have identified a brain network that measures placebo effects in Parkinson's disease patients. This breakthrough discovery has the potential to improve the accuracy of clinical trials by excluding subjects who are more likely to experience placebo effects.

Novel mechanism for invasion of EV71 virus demonstrated

A new study determines glycosylation and pH-dependent conformational changes of virus receptor SCARB2 as crucial for EV71 attachment and entry. Researchers found that SCARB2 opens a lipid-transfer tunnel to trigger viral uncoating at acidic conditions, releasing the viral genome into host cells.
