NIH grants totaling $17.9 million will advance UMass Amherst research tackling opioid overdose and HIV prevention and treatment

The research aims to develop an intervention for incarcerated people to address the challenge of engaging with MOUD treatment after release. Massachusetts has received federal approval for a Section 1115 waiver to provide Medicaid benefits to incarcerated individuals, expanding access to healthcare and support services.

PCI with a sirolimus-eluting balloon and provisional stenting shows comparable outcomes to routine DES implantation for treatment of de novo coronary lesion

A large international study found that utilizing sirolimus-eluting balloons with bailout stenting only if necessary was noninferior to routine DES implantation for treating de novo coronary artery disease. The results showed comparable outcomes, including low rates of cardiac death and target vessel myocardial infarction.

The Lundquist Institute’s Dr. Dong Chang receives $3.16 million NIH grant to improve ICU care and shared decision-making

Dr. Dong Chang has been awarded a prestigious R01 grant from the National Institutes of Health to develop a structured communication strategy that utilizes shared-decision making and time-limited trials to improve ICU care. The study aims to reduce non-beneficial treatments for critically ill patients with advanced medical illnesses.

Small study suggests 40Hz sensory stimulation may benefit some Alzheimer’s patients for years

A small study found that five volunteers with late-onset Alzheimer's disease showed significant improvements in cognitive tests and decreased biomarker tau proteins after two years of receiving 40Hz light and sound stimulation. This suggests that the therapy may slow cognitive decline and have direct biological impacts on Alzheimer's p...

New study reveals how immune cells help defend against candida infections

A new study shows that eosinophils, typically linked to allergies, play a protective role against Candida infections by recognizing the fungus and releasing proteins that stop its growth. This discovery opens the door to new therapies that could strengthen natural defenses against life-threatening fungal infections.

Physical fitness, physical activity and screen time influence adolescents’ brain function

Recent studies from the University of Eastern Finland suggest that an active lifestyle, good physical fitness and moderate screen time are crucial for brain development in adolescence. Better physical fitness was associated with increased excitability and stronger inhibition of the motor cortex, while passive screen time weakened corti...

From soft to solid: How a coral stiffens its skeleton on demand

A soft coral's ability to stiffen its skeleton in response to danger has been studied by Penn Engineers, revealing a mechanism known as granular jamming. By compacting mineral particles and expelling water, the coral's tissues create a rigid structure that can withstand external forces.

Scientists identify cells by seeing how high they levitate

Researchers at Stanford Medicine have created a new cell-sorting device that uses electromagnetic levitation to separate different types of cells, including cancer cells and live cells from dead cells. The device can precisely direct the movement of cells without attaching fluorescent labels or exposing them to harsh chemicals.

As global warming worsens, so may space communications

Researchers at Kyushu University found that rising CO2 levels in the atmosphere may lead to disruptions in shortwave radio communications, including systems used for air traffic control and maritime communication. The ionosphere's cooling due to global warming causes a decrease in air density and accelerates wind circulation.
