Scientists discover blueprint of body's heat sensor

Researchers have discovered the structure of TRPV2, a protein linked to pain and heat perception, which could lead to new treatments for chronic pain. The study found that TRPV2 has an in-between state where it becomes desensitized to repeated stimuli, suggesting a potential way to alleviate chronic pain.

Mapping out cell conversion

Researchers developed an algorithm called Mogrify that predicts the unique set of cellular factors required for converting one human cell type to another. This breakthrough has significant implications for regenerative medicine and lays the groundwork for further research into cell reprogramming.

Blood cells in action

Researchers demonstrate that fast molecules in the vicinity make blood cell membranes wriggle, but cells also become active when they have enough reaction time. The study reveals a balance between thermal fluctuations and internal forces causing the cells to change shape.

New research from MSK highlights fertility concerns of young adult and adolescent cancer survivors

A new study from MSK highlights the fertility concerns of young adult and adolescent cancer survivors, with nearly half reporting uncertainty about their reproductive health. The researchers emphasize the need for more comprehensive fertility-related information and support services in survivorship care.

Georgetown professors: Congress made 'scientific judgment for which it is distinctly unqualified'

Two Georgetown professors argue that a section of the FY 2016 Consolidated Appropriations Act undermines science and women's health by requiring private insurers to follow outdated scientific guidance for breast cancer screening coverage. This action strikes at the credibility of the US Preventive Services Task Force and may discourage...

2-for-1 bacterial virulence factor revealed

Researchers at Washington University in St. Louis have identified a virulence factor secreted by the bacterium Acinetobacter baumannii, which is resistant to traditional antibiotics. The discovery could lead to the development of new antivirulence antibiotics that can suppress pathogen growth without eliminating susceptible bacteria.

Gregarious chimps harbor richer gut microbiomes

Researchers found that the number of bacterial species in a chimp's GI tract increases when they are more gregarious. The study suggests that social interactions with other chimps help maintain gut microbial diversity over a lifetime, just as initial exposure from mom does.

The turbulent birth of a quasar

Researchers used ALMA to study W2246-0526, the most luminous galaxy known, finding it's ejecting its star-forming gas due to intense infrared radiation. This turbulence could lead to the galaxy evolving into a traditional quasar.

Mentally challenging activities key to a healthy aging mind

Researchers found that high-challenge activities improved memory performance and brain activity efficiency in older adults. The study suggests that mentally demanding activities may be neuroprotective and essential for maintaining a healthy brain into late adulthood. Enhanced neural efficiency was maintained a year after participation.

Predictability of DNA markers for population-level study based on species-level variation

Researchers used cactus species to test whether regions variable across closely related species show predictable intraspecific variability. The study found that rate-heterogeneity poses a practical challenge for researchers, and screening steps are necessary to discover regions of the genome with sufficient variability.
