Phys.org / Great Salt Lake's ancient past reveals how quickly fresh water can disappear
From a mountainside overlooking Utah's Great Salt Lake, a time traveler turning back the clock 20,000 years would watch a dramatic transformation of the landscape. The shallow, salty lake below would swell into an immense ...
Phys.org / Marine bacteria team up to break down one of the ocean's toughest carbon-storing molecules
Deep in the ocean, brown algae and diatoms produce a complex carbohydrate molecule called fucoidan, which helps form their protective outer layers. The fucoidan molecule is very difficult for microbes to break down because ...
Phys.org / Responsibilities in close social relationships explain Eastern–Western cultural differences
Do you think that a person who reorganizes their life so that their aging parents can live with them would be likely to push another out of the way on the subway? What about greeting strangers with a smile? The answers to ...
Phys.org / Laser altimeter BELA ready to explore Mercury's surface
Launched on Oct. 20, 2018, the joint ESA/JAXA BepiColombo mission has traveled for almost eight years, using a carefully planned but eventful sequence of planetary flybys and solar-electric propulsion to gradually approach ...
Phys.org / Mitotic chromosomes may assemble from pre-existing chromatin 'building blocks' during cell division
Inside each human cell, about 2 meters (6.6 feet) of genomic DNA must be accurately copied and equally transmitted to two daughter cells during cell division. To achieve this, the copied DNA is condensed into thick, short ...
Phys.org / New peanut genome map uncovers hidden gene, boosts dense-planting yields 20%
An international team that includes researchers from Murdoch University's Centre for Crop and Food Innovation (CCFI) has built the most comprehensive genetic map of the peanut yet and used this new genomic resource to breed ...
Phys.org / Examining Americans' complicated relationship with science
A new study finds that while most Americans are interested in science and believe it benefits society, the public's relationship with science is more complicated than those positive views suggest.
Phys.org / Scientists create 'super ice' that is ten times stronger and far harder to shatter
Ice is cheap, abundant and surprisingly strong. But it has one major weakness: Cracks can race through it, causing it to shatter without warning. Now, scientists have developed a new material that could overcome that problem. ...
Phys.org / Home advantage or pastures new? High-Arctic shorebirds rarely return to the same breeding area
Shorebirds are capable of some of the longest migrations on Earth, yet most return year after year to the same area to breed. Coming back has distinct advantages, including knowing the best spots to feed or roost, having ...
Phys.org / Robots and AI uncover unexpected pathway in classic 135-year-old chemical reaction
Chemical reactions are often written as simple equations: Starting materials go in, and a product comes out. In reality, the same substrates can follow many different pathways depending on their concentrations, temperature, ...
Phys.org / A 5,000-year-old royal mystery: Digital clues point to Meretneith as Egypt's female king
More than 5,000 years ago, a royal woman named Meretneith (also written as Merneith) lived in ancient Egypt. She was possibly the daughter of Djer, the third king of the First Dynasty, a period when the first kings ruled ...
Phys.org / Adaptive crystal can selectively capture CO₂ and recognize similar molecules
Chemical separation can be energy-intensive when molecules have similar sizes and properties. Researchers from Shibaura Institute of Technology, Japan, have now developed an interlayer adaptive crystal that changes its spacing ...
