Scientists at the Norwegian University of Science and Technology have found that chemicals in plastic could be helping drive rising rates of obesity around the world, by entering the human body and interfering with our metabolism. Source of Article
A new understanding of the way the body teaches immune cells to fight off threats has raised hopes of advanced treatments for autoimmune conditions such as multiple sclerosis, along with other diseases such as cancer. Source of Article
We generally don't think of fish as being a vocal bunch – after all, anglers don't typically use "fish calls" to lure them in. According to a new study, however, approximately two-thirds of all fish species probably use sound to communicate. Source of Article
Although concrete can be altered in order to help tiny cracks show up before they become catastrophic, scientists have now discovered that regular concrete does the job pretty well itself. It just needs a coat of ordinary paint, and a light source. Source of Article
Recent studies reported the discovery of lakes of liquid water below the polar ice caps on Mars, but others later refuted the find. Fueling the debate are two new independent studies, which have reached opposite conclusions. Source of Article
With temperatures as cold as to -232 °C, the lunar night is not a friendly place for electronics. Space technology company Masten has developed a more efficient, safer system that uses chemical reactions to keep lander electronics warm until dawn. Source of Article
While certain types of filtration media are great at removing pathogens from water, they do clog up over time, slowing their rate of filtration. According to new research, a solution to the problem may lie in the use of "living filtration membranes." Source of Article
How do whales gulp down huge amounts of water and krill without drowning themselves with every mouthful? Researchers have now discovered an “oral plug” in the throats of some species that blocks either their airways or esophagus as needed. Source of Article
Perovskite solar cells have come a long way in a short time, but there’s still room for improvement. Engineers have now added a layer of quantum dots to the recipe, resulting in a more stable solar cell with near-record efficiency. Source of Article
Scientists have developed an advanced new type of humidity sensor inspired by camel noses that is capable of detecting low levels of water molecules in the air, giving it the potential to help find water sources in extreme environments. Source of Article
