'Droplets' in disease

Proteins with ALS, cancer role do not assume a regular shape

: Our cells contain proteins, essential to functions like protein creation and DNA repair but also involved in forms of ALS and cancer, that never take a characteristic shape, a new study shows. Instead it’s how they become huddled with each other into droplets that matters. Scientists may therefore have to understand the code that determines their huddling to prevent disease.
Roger B. Henkle Memorial Lecture

Philosopher Slavoj Žižek to deliver Henkle Lecture

Slavoj Žižek, the renowned Slovenian cultural theorist and philosopher, will deliver the Roger B. Henkle Memorial Lecture, at Brown University on Tuesday, Oct. 13, 2015. His talk begins at 5:30 p.m. in Salomon Center for Teaching, De Ciccio Family Auditorium. The event is free and open to the public, but registration is required.

An accessible approach to making a mini-brain

In a new paper in Tissue Engineering: Part C, Brown University researchers describe a relatively accessible method for making a working – though not thinking – sphere of central nervous system tissue. The advance could provide an inexpensive and easy-to-make 3-D testbed for biomedical research.

When care turns costly, patients leave private Medicare

A new study finds that when elderly patients use more costly services such as nursing home, at-home, or acute hospital care they become more likely to find that private Medicare Advantage plans no longer serve their needs, driving them to transfer their coverage — and their costs — to traditional public Medicare.

Scientists control rats’ senses of familiarity, novelty

Brown University brain scientists didn’t just study how recognition of familiarity and novelty arise in the mammalian brain, they actually took control, inducing rats to behave as if images they’d seen before were new, and images they had never seen were old.

High-volume facilities better for nursing hip fractures

A new study finds that the volume of hip fracture cases seen at a skilled nursing facility in the prior 12 months is a good predictor of whether a facility can successfully discharge patients back home within 30 days. That information could help families trying to decide where to seek care for an elderly loved one.

Research improves efficiency from larger perovskite solar cells

Perovskite solar cells are cheaper to make than traditional silicon cells and their electricity conversion efficiency is improving rapidly. To be commercially viable, perovskite cells need to scale up from lab size. Researchers from Brown and the National Renewable Energy Laboratory report a method for making perovskite cells larger while maintaining efficiency.
