Phys.org / Life in fossil bones: What we can learn from tiny traces of ancient blood chemicals
Blood tests are useful tools for doctors and scientific researchers: they can reveal a lot about a body's health. Usually, a blood sample is taken to get a picture of the large molecules that are present, such as cholesterols, ...
Phys.org / New satellite method maps 'creeping drought' in Canada's mountain snow
Researchers at Concordia have developed a new method of measuring the amount of usable water stored in snowpacks. The comprehensive technique, known as snow water availability (SWA), uses satellite data and climate reanalysis ...
Phys.org / What ice-fishing competitions reveal about human decision-making
Whether gathering berries, hunting, or fishing, humans searching for food make decisions not only based on personal experience but also by observing others. In a large-scale field study, an international team of researchers ...
Medical Xpress / High blood pressure at birth tied to hypertension risk in childhood
High blood pressure at birth may be an early warning sign, setting the stage for cardiovascular disease later in life. A longitudinal study, the ENVIRONAGE birth cohort, set out to understand whether blood pressure (BP) levels ...
Phys.org / Asteroid that wiped out dinosaurs had limited impact on sharks and rays, study shows
A new study using advanced artificial intelligence (AI) has revealed that the asteroid strike that wiped out the dinosaurs 66 million years ago caused only a modest decline in shark and ray species. The findings, published ...
Phys.org / Mapping 'figure 8' Fermi surfaces to pinpoint future chiral conductors
One of the biggest problems facing modern microelectronics is that computer chips can no longer be made arbitrarily smaller and more efficient. Materials used to date, such as copper, are reaching their limits because their ...
Phys.org / Snowstorm disrupts travel in southern US as blast of icy weather widens
Travel misery was set to continue Sunday as a powerful snowstorm blasted southern US states, bringing subzero temperatures to regions not accustomed to the deadly winter conditions.
Medical Xpress / A benchmark for antibodies: Open dataset aims to standardize sequencing and measurement
Antibodies are the immune system's precision tools for recognizing and neutralizing viruses, bacteria and other foreign substances that can make us ill. These proteins circulate in the bloodstream and are built from chains ...
Phys.org / Novel nanomaterial uses oxidative stress to kill cancer cells
Scientists at Oregon State University have developed a new nanomaterial that triggers a pair of chemical reactions inside cancer cells, killing the cells via oxidative stress while leaving healthy tissues alone. The study ...
Tech Xplore / Taking the heat out of industrial chemical separations
The modern world runs on chemicals and fuels that require a huge amount of energy to produce: Industrial chemical separation accounts for 10% to 15% of the world's total energy consumption. That's because most separations ...
Phys.org / Ochre used in ancient graves in Finland reflects identity of deceased
Roughly 5,500–6,000 years ago, the area including present-day Finland was inhabited by hunter-fisher-gatherers living in small village-like clusters. Traveling via waterways, these people established permanent fishing systems, ...
Phys.org / Freestanding 3D MXene structures push the limits of microscale devices
In a breakthrough that could power next-generation electronics, sensors, and energy storage devices, CMU engineers have developed a fabrication technique that arranges MXene nanosheets, each a million times thinner than a ...
