Buoys warn swimmers of dirty water

Is the water in your local lake clean enough to swim in today? Currently, the only way to find out is for someone to take a water sample, bring it back to a lab, then report the analysis 24 to 48 hours later. Soon, however, water-sampling buoys anchored off of beaches could provide readings in real time.Read More

Mapping the thesaurus of the human brain

Researchers from the University of California, Berkeley (UC Berkeley) have used MRI data to create what they call a "semantic atlas," using vivid colors in multiple dimensions to show how the brain organizes language. The greater understanding that the map provides could one day help patients suffering from conditions such as motor neuron diseases and strokes in making themselves understood.Read More

Cracking a few eggs to make electronics that dissolve

Durability is often touted as the hallmark of good electronics, but sometimes you want components that don't last all that long. For example, it would be handy if microelectronic systems that delivered drugs to various parts of the body dissolved after their task was done. Or if sensors that monitor pollution simply dissolved after they were finished reporting, rather than contributing to even more environmentally-damaging material. A team of researchers from the UK and China has just figured out how to create one such chip out of eggs.Read More

Increased CO2 levels are greening the Earth

Researchers studying NASA satellite data on the Earth's vegetation coverage have discovered that plants have significantly increased their leaf cover over the last 35 years to the point that new growth across the planet is equivalent to an area twice as large as the continental United States. According to the study, the largest contributor to this greening is the growing level of carbon dioxide (CO2) in the atmosphere.Read More

New imaging technique provides "drone's eye" view of Mars

University College London (UCL) has released images of the Martian surface with five times the resolution of anything previously sent back from Mars orbit. The images come courtesy of the new Super-Resolution Restoration (SRR) imaging technique developed by a UCL research team, which takes images from spacecraft orbiting Mars and stacks and matches them to create new, more detailed images of the Beagle 2 lander, ancient Martian lake beds, and the tracks of the NASA MER-A rover.Read More

Hubble discovers new moon in our Solar System

A team of astronomers has announced the discovery of a new moon located in the far reaches of our Solar System, orbiting the little-known dwarf planet Makemake. Tentatively designated S/2015 (136472), or MK 2 for short, this newest addition to our little patch of the Milky Way could shed light on the enigmatic nature of minor planets traversing the Kuiper Belt.Read More

The world's tiniest thermometer is made from DNA

Researchers at the University of Montreal have created a thermometer that's an astonishing 20,000 times smaller than a single human hair. The work could lead to significant improvements in our understanding of how the human body functions on the nanoscale.Read More
