Phys.org / Curiosity Mars rover discovers field of honeycomb textures
As NASA's Curiosity rover recently began climbing a Martian valley nicknamed "Valle Grande," it sent back images that were a familiar sight to mission scientists: honeycomb-like textures called polygonal fractures, each about ...
Phys.org / New theory on how six‑tonne Stonehenge rock was transported from Scotland thousands of years ago: On a glacier
Built from stones weighing between 2 and 25 tonnes (2 to 28 tons), the structure of Stonehenge demonstrates a scale of construction hard to imagine before the invention of the wheel. The mystery deepens when you consider ...
Medical Xpress / New wearable stickers simplify cystic fibrosis diagnosis
A pair of wearable stickers may transform diagnostic sweat testing for cystic fibrosis (CF), a genetic disorder that causes problems with digestion and breathing.
Phys.org / Laying odds on the potential for Martian water near future landing zones
We know Mars has water ice in its polar regions, but astronauts (and their solar-powered equipment!) would much rather experience life closer to Mars' equator. As NASA looks toward landing humans on the red planet, the Planetary ...
Medical Xpress / Brain fluid structure may flag future dementia risk years before diagnosis
Dementia, a progressive loss of memory and decline in mental function that can be caused by various neurological conditions, is estimated to affect more than 57 million people worldwide. Identifying specific biological and ...
Phys.org / The Arctic Ocean keeps permafrost carbon firmly locked
Permafrost in the Arctic stores large quantities of organic carbon. When frozen ground thaws or coastal sections erode, this carbon can enter the sea, where microorganisms can break it down and convert it into climate-damaging ...
Phys.org / Magnetic nanoparticles remove forever chemicals from water
PFAS, otherwise known as forever chemicals, have become commonplace in numerous everyday and industrial products. At the same time, they are some of the most problematic pollutants of our times: They are extremely durable, ...
Phys.org / Photonic time crystals unlock ultrafast control of light in the terahertz range
An international team of researchers from École Polytechnique, Collège de France and Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has achieved a world first: the experimental realization of an all-optical photonic time crystal ...
Medical Xpress / Silencing a brain receptor curbs cancer cachexia and boosts mouse survival
A new path has opened toward stopping cancer-associated cachexia, a devastating complication that gradually wastes patients away. A KAIST research team has developed an RNA-based therapeutic strategy that blocks a brain signal ...
Medical Xpress / CRISPR acts as commander-in-chief for backup defenses in bacteria
The main function of CRISPR-Cas systems is to defend bacteria against various threats, including viruses called bacteriophages. Researchers have continued to study all varieties of CRISPR-Cas systems (to date, two classes, ...
Phys.org / Early Cambrian fossil uncovers key buoyancy structure at the dawn of cephalopod evolution
Extant and ancient cephalopods—including octopuses, squids, extinct ammonites, cuttlefish and nautiluses—have all had to solve the problem of buoyancy, whether they have hard external shells or not.
Medical Xpress / The first 72 hours: Hospital routines may undermine breastfeeding
An evidence review of international research suggests widespread misconceptions within the medical community about early milk production, pacifiers and breast pumps may be undermining breastfeeding success in the critical ...
