SpaceX gets nod to put 12,000 satellites in orbit  

Washington DC (AFP) Nov 16, 2018 SpaceX got the green light this week from US authorities to put a constellation of nearly 12,000 satellites into orbit in order to boost cheap, wireless internet access by the 2020s. The SpaceX network would vastly multiply the number of satellites around Earth. Since the world's first artificial satellite, Sputnik, was launched in 1957, humanity has sent just over 8,000 objects into

The Bitter Truth: Coffee Lovers' Love of Caffeine is Wired in their DNA  

Are you a coffee drinker? This banal get-to-know-you question becomes strange when you really think about the anticipated dichotomy of a firm yes or no answer. A few people might dabble in the delicious, charming, soul-warming beverage (you can see where my allegiances lie), but many more seem to either love or hate the bitter stuff. People on either end of the coffee spectrum might think of the other, are you seriously tasting what I'm tasting? It would make sense if the answer was no...

Simply Seeing and Smelling Food Preps the Liver for Digestion  

After a long day's work, sometimes you can't help but drool over that hot, tempting meal sitting in front of you. Well, it turns out that your liver can't either. A new study published in Cell Reports on November 15 suggests that simply seeing and smelling food preps your body for delicious digestion. The research shows that the specific neurons activated in freshly-fed mice were also activated in mice exposed to just the sight and aroma of food. These inaccessible treats caused the...

A newborn baby's brain responds to being touched on the face, according to new research. Babies use this sense of touch -- facial somatosensation -- to find and latch onto their mother's nipple, and should have this ability from birth. Premature babies often have difficulty feeding, and underdevelopment of their facial sensitivity may be one of the main causes.

Dodging antibiotic resistance by curbing bacterial evolution  

Lowering mutation rates in harmful bacteria might be an as yet untried way to hinder the emergence of antimicrobial pathogens. One target for drug development might be a protein factor, DNA translocase Mfd, that enables bacteria to evolve rapidly by promoting mutations in many different bacterial species. This action speeds antibiotic resistance, including multi-drug resistance. Working on drugs to block Mfd and similar factors could be a revolutionary strategy to address the worldwide crisis of

Neuroscientists report that BH4 also functions as a kind of immunological thermostat, raising and lowering the activity levels of T cells. Inhibiting BH4 could relieve atopic dermatitis, psoriasis, lupus, polyarthritis and inflammatory bowel disease; boosting it could help the immune system attack cancers.

Overflowing crater lakes carved canyons across Mars  

Today, most of the water on Mars is locked away in frozen ice caps. But billions of years ago it flowed freely across the surface, forming rushing rivers that emptied into craters, forming lakes and seas. New research has found evidence that sometimes the lakes would take on so much water that they overflowed and burst from the sides of their basins, creating catastrophic floods that carved canyons very rapidly, perhaps in a matter of weeks.

For 60 years, scientists observing Formica archboldi, a species of ant native to Florida, have documented something...odd.

Further investigation demonstrated that the drug cilnidipine suppressed Drp1-filamin A complex formation and preserved heart cell function.
