Phys.org / The cost of memory: How organisms balance thinking and sensing
Remembering the past can help living organisms make better decisions, but memory comes at a cost. Whether it is an animal searching for food or a single cell responding to its surroundings, storing and using information requires ...
Phys.org / Mosquitoes are rapidly activating enzymes against common insecticide, researchers warn
Traditionally, public health programs have relied on chemicals for mosquito management, which may be why combating mosquitoes is becoming more difficult. Over time, insecticides trigger biochemical and genetic variations ...
Phys.org / First Arctic Ocean 2050 expedition on its way to the North Pole
On July 23, R/V Kronprins Haakon cast off from the coal quay in Longyearbyen. Around 30 researchers and 20 crew members will spend the next 50 days sailing toward the North Pole as part of the Polhavet 2050 research program.
Medical Xpress / Weaker rest-activity rhythm, unfavorable sleep profile linked to overactive bladder
Weaker rest-activity rhythms (RARs) and unfavorable sleep profiles are associated with a higher prevalence of overactive bladder (OAB), according to a study published online July 17 in Neurourology and Urodynamics.
Phys.org / DNA studies uncover a forgotten population at the top of the world
Scientists have uncovered an ancient population previously unknown to science in Ladakh, a high-altitude region in northern India. Their studies revealed individuals with a nearly perfect 50–50 mix of South Asian-related ...
Phys.org / 100% organic free-range egg production could have negative consequences for climate and nature
A study published in Royal Society Open Science reveals striking trade-offs when it comes to different methods of egg production. Using UK data, the study compared several possible scenarios for the egg industry, including ...
Phys.org / California drought may have pushed parts of the Sacramento Valley aquifer toward permanent collapse
Around a quarter of the U.S. food supply is grown in California's Central Valley. Most of its crops, like rice, fruit trees and nut trees, are water-intensive and require extensive groundwater pumping during droughts. Over ...
Phys.org / Deformed head shapes in fossilized humans show their infants were probably just as helpless as modern human babies
Archaic human parents had to look after helpless infants like modern-day parents do, according to new research. Human babies are born less developed than those of other great apes and are therefore unable to move as freely. ...
Phys.org / New theory on how six‑tonne Stonehenge rock was transported from Scotland thousands of years ago: On a glacier
Built from stones weighing between 2 and 25 tonnes (2 to 28 tons), the structure of Stonehenge demonstrates a scale of construction hard to imagine before the invention of the wheel. The mystery deepens when you consider ...
Phys.org / Evidence of giant rings in Venus's atmosphere uncovered in archived observations
In 2010, scientists waiting to use the William Herschel Telescope in the Canary Islands captured a brief 36 minutes of images of Venus. They were waiting for the sun to set so they could look at distant stars and dust disks ...
Phys.org / Queen bee pheromones help daughters decide whether to stay or leave the nest
Female sweat bees need to make a pivotal life decision: remain in the nest to help their mother raise more offspring or leave to establish nests of their own. New research from the Smithsonian Tropical Research Institute ...
Phys.org / Astronomers find strongest evidence yet that Betelgeuse has a companion
At long last, astronomers have firm evidence that Betelgeuse, one of the most famous stars in the night sky, is not alone. Using the European Southern Observatory's Very Large Telescope (ESO's VLT), a team led by French researcher ...
