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 / Not all exercise is equal when it comes to metabolic syndrome risk
Not every disease announces itself with obvious symptoms. Some develop quietly, going unnoticed until they begin to take a serious toll on health. Metabolic syndrome (MetS) is one of them. Rather than a single disease, it ...
Phys.org / A backup fluoride defense in soil bacteria could aid greener chemical production
Researchers at the University of Tartu have discovered a mechanism in bacteria that helps them adapt to fluoride, which is toxic to most organisms above relatively low threshold concentrations. Their discovery may represent ...
Phys.org / Shark finning regulations have not significantly changed global trade, new analysis finds
Much like caviar, shark fins are a luxury product and delicacy in parts of the world. And like wild caviar, demand for shark fins has posed an incredible threat to species that can't reproduce quickly enough to keep up.
Phys.org / Cretaceous beetle fossil reveals early evolution of firefly sensory and signaling systems
Scientists have discovered a remarkably well-preserved 100-million-year-old beetle fossil that provides a rare glimpse into the evolution of the intricate sensory and communication systems used by fireflies and their relatives ...
Phys.org / New photonic platform offers a four-lane highway for light
Topological photonics can force propagating light to travel in a single direction—allowing researchers to route optical signals around corners and past defects without any of it scattering backward. So far, however, this ...
Phys.org / Experts survey the glacier ice on Mount Ararat for the first time
Facing wind and cold, with only half as much oxygen to breathe as in the valley, a German-Turkish research team surveyed the glacier on Mount Ararat in eastern Turkey for the first time in July, at more than 5,000 meters ...
Medical Xpress / Exacerbation risk profiles vary with house dust mite sensitization in pediatric asthma
For children with asthma, exacerbation risk is associated with distinct profiles depending on house dust mite (HDM) sensitization status, according to a study published online July 16 in the International Journal of Occupational ...
Phys.org / Less-explored form of quantum code could be more powerful—and more stable—than its alternative in error correction
In mathematics and getting dressed, some processes are commutative, while others are noncommutative. Commutative means the order doesn't matter (3 + 2 is the same as 2 + 3, and it doesn't matter which sock goes on first). ...
Medical Xpress / Mighty mitochondria: Scientists uncover new role for fighting bacterial infections, including drug-resistant superbugs
Beyond the nucleus, no other organelle in eukaryotic cells captures the public's imagination quite like mitochondria: They are the engines of cellular energy production; they possess their own DNA, and they are passed from ...
Medical Xpress / Hyperuricemia predicts mortality with chronic kidney disease
Hyperuricemia independently predicts mortality in chronic kidney disease (CKD), according to a study published online July 13 in the Journal of Clinical Medicine.
Phys.org / Smarter fish farms could cut electricity use and CO₂ while keeping fish safe
Recirculating aquaculture systems (RAS) are attracting growing attention as a sustainable aquaculture technology that can reduce water use, control rearing conditions and lower environmental impacts by filtering and reusing ...
