Phys.org / Ice Age artists carved thumbnail-size bird figurines from mammoth ivory 40,000 years ago
Excavations at Hohle Fels Cave in the UNESCO World Heritage area of the Swabian Jura in southwestern Germany have again yielded two spectacular 40,000-year-old depictions of birds carved from mammoth ivory. The two figurines ...
Phys.org / In biology of cells, octopus has another trick up its sleeve
The octopus is a biological oddity. It can use tools, open jars, and its complex nervous system supports as many neurons as a small primate. Now Harvard biologists have discovered a mysterious distinction in octopuses' core ...
Medical Xpress / Nurse-led initiative reduces unplanned extubations
A nurse-led initiative at a New Jersey hospital reversed an upward trend of unplanned extubation rates in its medical intensive care unit (MICU) and maintained the improvement for five years, according to an article published ...
Medical Xpress / Supercharged millet could help children's gut health without usual supplement side effects
Every day in the urban slums of Mumbai, hundreds of young children were fed toddler-appropriate porridge, soft curry or fresh-baked goods. For some, these were made of ordinary pearl millet, an ancient grain common in the ...
Phys.org / How fitness, speed and position shape competition in expanding populations
A study published in the Journal of Statistical Mechanics: Theory and Experiment (JSTAT), inspired by the behavior of bacterial colonies observed in previous experiments, uses mathematical models to describe the expansion ...
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 / Little red dots may mark temporary black hole phase
Since their discovery by NASA's James Webb Space Telescope in 2022, little red dots (LRDs) have been the subject of great interest to astronomers. Understanding the nature of these extremely distant, compact red sources has ...
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 / Rural communities face serious obstacles in promoting physical activity
People in rural communities have long experienced disproportionate levels of chronic disease, driven in part by systemic barriers to physical activity. A new study from North Carolina State University highlights ways some ...
Phys.org / Waste CO₂ converts into graphite through a newly observed two-step process
Graphite, the carbon core of a humble No. 2 pencil, is also an essential component in technologies such as batteries, smartphones, laptops and industrial power equipment. Today, nearly all of this critical mineral must be ...
Medical Xpress / Experimental treatment significantly slows progression of a fatal brain disease in women during clinical trial
Researchers at Tel Aviv University have presented new findings indicating that the experimental drug Davunetide may significantly slow the progression of progressive supranuclear palsy (PSP) in women, who exhibited a markedly ...
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.
