Membrane ‘neighborhood’ helps transporter protein regulate cell signaling

Researchers at St. Jude Children's Research Hospital identified a protein network that stabilizes ABCC4 transporters in place to maintain cyclic AMP signaling levels. The discovery reveals a previously unappreciated protein neighborhood and opens new therapeutic opportunities for regulating ABC transporters.

Although public overwhelmingly supports hepatitis B vaccine for a newborn, partisan differences exist

A national survey of adults found that three-quarters support vaccinating newborns against hepatitis B, but Republicans are less likely to recommend the vaccine. The survey also found that most respondents believe the vaccine protects against liver disease, and there is little evidence justifying delaying vaccination.

Visual system of butterflies changes with seasons

A team of researchers found that common buckeye butterflies change their eye tissue gene expression between summer and fall, indicating they see their environment differently. The study confirms seasonal patterns in the expression of many genes important for vision and eye development.

America doesn’t have enough hospital beds. This could help.

A new study from Michigan Medicine found that its data-driven command center increased hospital bed use efficiency by 63%, reducing emergency department boarding time by 33% and patient transfers by 13%. The initiative also streamlined discharge processes, resulting in a 12% drop in waiting times for patients ready to leave the hospital.

Engineering the next superfood: BTI unlocks goldenberry’s commercial potential

Researchers at Boyce Thompson Institute engineered compact goldenberry plants that are 35% shorter than their wild relatives, making them viable for commercial agriculture. These new plants have the same nutritional profile as commercially available goldenberries but can be grown at higher density and with reduced maintenance.

Virtual companions, real responsibility: Researchers call for clear regulations on AI tools used for mental health interactions

The researchers argue that systems imitating human behavior must meet appropriate safety requirements and operate within defined legal frameworks. They recommend that LLMs clearly state that they are not an approved mental health medical tool, refrain from impersonating therapists, and limit themselves to basic, non-medical information.

New approach narrows uncertainty in future warming and remaining carbon budget for 2 °C

A new study improves projection accuracy by combining climate model projections with observational data. The analysis reveals that many models overestimate global warming and refines estimates of the remaining carbon budget, narrowing the uncertainty range from 352-702 billion tons to 251-666 billion tons.

Sibling roles change when a parent dies

A comprehensive study of Korean families reveals that sibling roles shift significantly after a parent's death. Eldest sons initially provide financial support, while eldest daughters take on primary caregiving responsibilities in the terminal phase. Younger siblings tend to contribute less to both care and household support.
