When stem cells feel the squeeze, they start building bone

Researchers found that human stem cells can differentiate into bone cells simply by being squeezed through narrow spaces. This discovery could lead to the development of simpler and safer regenerative therapies by using physical signals instead of chemical cues. The study's findings have broader implications, including potential applic...

Study shows people back climate policy when weather events feel personal

A new study published in Nature Climate Change found that most people are more likely to support climate policies if they see a connection between extreme weather and climate change. Strong support was observed in African and Asian countries, as well as among individuals who attribute extreme weather events to climate change.

Experts urge evidence-based regulations of 7-OH, not restriction, as new science emerges showing safe use

A combination of data from the FDA and independent studies confirms 7-OH's strong real-world safety profile, with no confirmed deaths reported despite over half a billion estimated doses consumed nationwide. The analysis also found that 7-OH has a significantly lower risk profile than many other natural compounds currently on the market.

Can one video change a teen's mindset? New study says yes - but there’s a catch

A new study published in JCPP Advances found that watching a ten-minute video can shift how teenagers view themselves by promoting mental well-being. The intervention appeared to have little immediate effect on symptoms of anxiety or depression, but may work best as part of a broader toolkit of services.

New research shows Americans can’t tell healthy processed foods from unhealthy ones

A recent survey found that 39% of respondents incorrectly identified all processed foods as unhealthy. However, the Physicians Committee for Responsible Medicine reports that it is not processed plant foods but rather meat consumption associated with an increased risk of type 2 diabetes and cardiovascular disease.

Medtech innovator GeniPhys receives FDA clearance for first-in-kind self-assembling collagen scaffold for applications in advanced wound care

GeniPhys has received FDA clearance for its self-assembling collagen scaffold, Collymer Self-Assembling Scaffold (SAS), which supports cellular infiltration and vascularization. The technology is indicated for various wound types and anchors a growing intellectual property portfolio with nearly 20 issued or pending patents.

Skin-to-skin contact with babies increased significantly after training

A new study from Uppsala University finds that targeted training for healthcare professionals and parents significantly increases skin-to-skin contact between newborns and their parents in the first 48 hours after birth. This leads to improved health benefits for both the baby and parent, with a notable increase in the proportion of ba...

Global ocean analysis could replace costly in-situ sound speed profiles in seafloor positioning, study finds

A new study reveals that global ocean analysis products can replace expensive in-situ sound speed measurements for precise seafloor positioning. Global ocean analysis achieves centimeter-level accuracy, comparable to traditional methods, and reduces costs and logistical challenges in marine geodetic surveys.

New LED-based imaging system could transform cancer detection in endoscopy

A new prototype imaging system combines light-emitting diodes (LEDs) with hyperspectral imaging technology to create detailed maps of tissue properties invisible to conventional cameras. The system shows promise for cancer detection during endoscopy, achieving real-time speeds and high-quality data comparable to reference systems.
