Novel Anti-Inflammatory Molecule Isolated from Soil-Dwelling Bacterium

Breaking Science News - 18 hours 36 min ago
About three decades after scientists coined the term ‘hygiene hypothesis’ to suggest that increased exposure to microorganisms could benefit health, an international team of biologists from the United States, the United Kingdom and Hungary has identified an anti-inflammatory lipid in the soil-dwelling bacterium Mycobacterium vaccae that may be responsible. Professor David Strachan from the London [...]

High reaction rates even without precious metals

Science Daily Top Science - 19 hours 36 min ago
Non-precious metal nanoparticles could one day replace expensive catalysts for hydrogen production. However, it is often difficult to determine what reaction rates they can achieve, especially when it comes to oxide particles. This is because the particles must be attached to the electrode using a binder and conductive additives, which distort the results. With the aid of electrochemical analyses of individual particles, researchers have now succeeded in determining the activity and substance conversion of nanocatalysts made from cobalt iron oxide -- without any binders.

A miniature robot that could check colons for early signs of disease

Science Daily Top Science - 19 hours 36 min ago
Engineers have shown it is technically possible to guide a tiny robotic capsule inside the colon to take micro-ultrasound images. Known as a Sonopill, the device could one day replace the need for patients to undergo an endoscopic examination, where a semi-rigid scope is passed into the bowel - an invasive procedure that can be painful.

Extreme pressure and heat in Earth's mantle simulated

Science Daily Top Science - 20 hours 58 min ago
Unlike flawless gems, fibrous diamonds often contain small saline inclusions. These give hints to scientists about the conditions under which diamonds are formed deep in the Earth's mantle. A research team has now solved the puzzle of the formation of these inclusions by simulating conditions of extreme heat and pressure in the laboratory.

‘Meteoric Smoke’ May Play Key Role in Formation of High-Altitude Clouds on Mars

Breaking Science News - Wed, 2019-06-19 23:18
Planetary scientists have long observed water-ice clouds in the Martian middle atmosphere (18.6-37.2 miles, or 30-60 km, above the surface). Now, a University of Colorado, Boulder-led study suggests that those clouds owe their existence to a phenomenon called ‘meteoric smoke.’ “Clouds don’t just form on their own. They need something that they can condense onto,” [...]

The secret of platinum deposits revealed by field observations in South Africa

Science Daily Top Science - Wed, 2019-06-19 22:13
There are two competing ideas of how platinum deposits formed: the first involves gravity-induced settling of crystals on the chamber floor, while the second idea implies that the crystals grow in situ, directly on the floor of the magmatic chamber. Researchers have established that the crystals grow in situ, with its high platinum status being attained while all its minerals were crystallizing along the cooling margins of the magma chamber.
