Medical Xpress / Epigenetic changes regulate gene expression, but what regulates epigenetics?
All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in each cell. Mistakes or ...
Phys.org / Scientists map 3D structure of ZAK protein involved in cellular stress response
In an effort to reveal the inner workings of a protein that serves as a cell's damage detection system, scientists at Johns Hopkins and the Ludwig-Maximilians-University Munich (LMU) have published what is believed to be ...
Tech Xplore / AI tool helps visually impaired users 'feel' where objects are in real time
Over the last few years, systems and applications that help visually impaired people navigate their environment have undergone rapid development, but still have room to grow, according to a team of researchers at Penn State. ...
Phys.org / Three key pathways identified for scaling up actionable climate knowledge
There's no one-size-fits-all solution to adapting and building resilience to climate change, but a new study led by the University of Michigan offers three generalized pathways to help climate knowledge achieve its maximum ...
Phys.org / Magnetically reconfigurable ribbons let scientists 'program' liquids on demand
Materials Science and Engineering Department professor and UConn IMS resident faculty member, Xueju "Sophie" Wang's group has unveiled a simple but powerful way to control liquids: magnetically reconfigurable, multistable ...
Phys.org / Sloshing ferrofluids harness vibration energy: A new spin on powering tomorrow's wearables and IoT
Modern devices, from fitness trackers and smart garments to Internet of Things (IoT) sensors, require compact and sustainable power sources. In new research published in Scientific Reports, scientists present an energy harvester ...
Medical Xpress / Fluoridated water linked to better adolescent school achievement
Children exposed to recommended levels of fluoride in drinking water show modest cognitive advantages in secondary school, with no clear evidence of harm to cognitive functioning around age 60, according to researchers at ...
Medical Xpress / A retail approach nudges healthier choices in food relief
A University of Adelaide study, conducted in collaboration with Foodbank SA & NT, has demonstrated that strategies supermarkets commonly use to influence shopper behavior can be successfully adapted for food relief pantries.
Phys.org / Cosmic dust vital for sparking life in space, study suggests
Tiny particles of space dust could be vital for creating the complex molecules needed for life more quickly, scientists say.
Phys.org / How stories of personal experience cut through climate fatigue in ways that global negotiations can't
When Cop30 convened in Belém, deep inside the Amazon, the world's attention turned once again to negotiations, emissions pledges and political maneuvering. The global stage was set against one of Earth's most biodiverse ...
Phys.org / Sea level doesn't rise at the same rate everywhere: Mapping where Antarctica's ice melt would have the biggest impact
When polar ice sheets melt, the effects ripple across the world. The melting ice raises average global sea level, alters ocean currents and affects temperatures in places far from the poles.
Medical Xpress / Long-term calorie restriction may slow normal brain aging
As the brain ages, cells in the central nervous system experience metabolic dysfunction and increased oxidative damage. These cellular issues impair the ability to maintain the myelin sheath (the protective covering around ...
