Phys.org / New enzyme atlas rewrites decades of biology research
WEHI researchers have led a major global effort to create the first authoritative atlas for a class of enzymes that regulate almost every cellular process in the human body. Published in Cell, the study establishes the first ...
Phys.org / Bacteria invent another way to turn on genes
In their landmark 1961 paper on the lac operon, Nobel laureates François Jacob and Jacques Monod speculated that RNA might control gene activity in bacteria through base-pairing interactions. But once protein transcription ...
Phys.org / Ancient DNA finds 15,800-year-old dogs in Anatolia, buried like humans
Evidence of some of the earliest dogs has been identified at two University of Liverpool/British Institute at Ankara archaeological excavation projects in central Anatolia, Turkey. Shedding new light on the development and ...
Phys.org / Study explains Antarctic sea ice growth and sudden decline
A new Stanford University study has helped solve a mystery about dramatic swings in sea ice extent around Antarctica.
Phys.org / Liquids can fracture like solids—researchers discover the breaking point
In a development that could shift our basic understanding of fluid mechanics, researchers from Drexel University have reported that, given the right circumstances, it is possible to induce a simple liquid to fracture like ...
Phys.org / Ancient DNA reveals earliest known dogs lived alongside Ice Age humans
The bond between humans and dogs is one of nature's most enduring partnerships, but exactly when it began has long been a mystery. Now, a new study has turned back the clock. The study, titled "Dogs were widely distributed ...
Phys.org / Artemis II astronauts arrive at Florida launch site for first moon trip in 53 years
The astronauts set to become the first lunar visitors in more than half a century arrived at their launch site Friday, joining the towering rocket that stands poised to blast off next week and send them around the moon.
Phys.org / Alaska analysis shows continued loss of Arctic landfast sea ice
Sea ice is sticking to Alaska's northern coast for less time each year, according to 27 years of data analyzed by University of Alaska Fairbanks scientists. Such landfast ice, which stays attached to the shoreline instead ...
Phys.org / Saturday Citations: Birthday cetaceans; quantifying children's play experiences; placebos still effective
This week, we learned that across the animal kingdom, sperm cells have a short shelf life. A study implicated autoantibodies in the development of long COVID. And among its other drawbacks, the weedkiller glyphosate may foster ...
Phys.org / JWST solves decades-long mystery about why Saturn appears to change its spin
Researchers at Northumbria University have used the most powerful space telescope ever built to answer one of the longest-standing puzzles in planetary science—why does Saturn appear to spin at a different speed depending ...
Phys.org / Scientists testing new scanning technology discover mysterious structure beneath an ancient Egyptian city
Archaeologists working in Egypt's Nile Delta may have discovered a tomb or temple dating back around 2,600 years while testing a new technology designed to locate structures buried deep beneath the surface. The team was studying ...
Phys.org / Japan's giant caldera volcano is refilling 7,300 years later
The magma reservoir of the largest volcanic eruption of the Holocene is refilling. This Kobe University insight on the Kikai caldera in Japan allows us to understand giant caldera volcanoes like Yellowstone or Toba more generally ...
