A team has used a process known as DNA origami to make electrochemical sensors that can quickly detect and measure biomarkers.
Beehive sensors offer hope in saving honeybee colonies
A computer science team has developed a sensor-based technology that could revolutionize commercial beekeeping by reducing colony losses and lowering labor costs. The technology uses low-cost heat sensors and forecasting models to predict when hive temperatures may reach dangerous levels. The system provides remote beekeepers with early warnings, allowing them...
Honeybee dance ‘styles’ sway food foraging success
Biologists have learned several interesting patterns related to bee communication. One such observation was that bees have consistent, unique ways of dancing, meaning each bee has its own 'style' that it adds to the communication. Could the success of the waggle dance be related to this uniqueness? Would bees that...
Climate change effects in 24,000 US lakes
Each summer, more and more lake beaches are forced to close due to toxic algae blooms. While climate change is often blamed, new research suggests a more complex story: climate interacts with human activities like agriculture and urban runoff, which funnel excess nutrients into the water. The study sheds light...
Brewing tea removes lead from water
Researchers demonstrated that brewing tea naturally adsorbs heavy metals like lead and cadmium, effectively filtering dangerous contaminants out of drinks. Researchers tested different types of tea, tea bags and brewing methods. Finely ground black tea leaves performed best at removing toxic heavy metals. Longer steeping times helped tea remove larger...
Heat-stressed reefs may benefit from coral-dwelling crabs
Crab behavior suggestive of wound-tending may improve coral tolerance to heat waves.
Scientists invent new drug candidates to treat antibiotic-resistant bacteria
There's an arms race in medicine -- scientists design drugs to treat lethal bacterial infections, but bacteria can evolve defenses to those drugs, sending the researchers back to square one. A team describes the development of a drug candidate that can stop bacteria before they have a chance to cause...
As dengue spreads, researchers discover a clue to fighting the virus
This research comes as dengue-carrying mosquitoes expand their territory into new regions, including Southern California.
Arctic study urges stronger climate action to prevent catastrophic warming
Remember when 2 degrees Celsius of global warming was the doomsday scenario? Well, we're now staring down the barrel of something much worse. From the fish on your plate to the weather outside your window, everything's about to change. A new study underscores the grave risks posed by insufficient national...
Mega-iceberg from Antarctica on collision course with South Georgia: Harbinger of things to come?
It is no strange sight to see icebergs break off of the Antarctic ice cap and drift away, like the gigantic sheet of ice that is currently heading for the island of South Georgia. But climate change is making it happen more frequently, with ever-larger icebergs in the waters around...
