Phys.org / The battle of the sexes in the egg: How early nuclear rivalry helps embryos develop properly
The sperm and the egg cell's nuclei compete for size directly after fertilization and this is necessary for proper embryonic development. A mouse study with Kobe University participation finally gives meaning to a phenomenon ...
Phys.org / Mini-antibodies reactivate the 'guardian of the genome'
Each year, 20 million people are diagnosed with cancer. Various organs can be affected, and cancer types sometimes differ greatly at the cellular and molecular level. In about half of all cases, however, the protein p53 is ...
Phys.org / Molecular probe upgrade could make off-target drug effects easier to measure
A UCLA-led international research collaboration has unveiled a new technology that may help scientists better understand how small molecules, including many drugs, bind to proteins. The invention works with an existing lab ...
Phys.org / AI speeds chemists' search for better disinfectants
Chemists and computer scientists tapped AI to find new disinfectants to combat the growing threat of dangerous "superbugs." Their computational-experimental framework for developing quaternary ammonium compounds, or QACs, ...
Phys.org / Environmental DNA in NYC's East River reveals clues about nearby human and animal residents
Sequencing environmental DNA—or eDNA—from the East River in New York City can effectively monitor human diets and local wildlife, as well as the river's fish populations, report Mark Stoeckle and Jesse Ausubel of The Rockefeller ...
Phys.org / Molecular quantum nanosensors reveal temperature and radical signals inside living cells
Researchers at the National Institutes for Quantum Science and Technology (QST), Japan, and The University of Tokyo, Japan, in collaboration with Kyushu University, Japan, have developed a new class of biocompatible molecular ...
Phys.org / Thinner than hair and stretchable like rubber, this new shield tackles a space-age problem in one layer
Shielding materials are essential in key modern industrial settings—such as spacecraft, nuclear power plants, semiconductor equipment, and advanced medical devices—to protect both equipment and personnel from electromagnetic ...
Phys.org / How a free flow of information can amplify incorrect ideas
The idea that information should flow freely is deeply embedded in the design of social media. The assumption is that the more information is produced and shared, the better. However, simulations by a team of scientists including ...
Phys.org / Ancient farming clues may finally expose where humanity's most important wheat first emerged
The exact origin of bread wheat (Triticum aestivum) is still a mystery, but researchers believe they are edging closer to the source of one of the most important food staples worldwide. Using genetic studies and ancient plant ...
Phys.org / Invisible fertility crisis: Chemicals and climate change threaten reproduction across species
The rise in infertility is not limited to humans, as environmental stressors are quietly undermining the reproductive potential of different forms of life. A recent review published in npj Emerging Contaminants investigated ...
Phys.org / ALMA reveals giant molecular clouds across Needle galaxy's full disk
An international team of astronomers has employed the Atacama Large Millimeter/submillimeter Array (ALMA) to perform high-resolution observations of the Needle galaxy. Results of the new observational campaign, presented ...
Phys.org / AI slashes the time needed to design better heat-harvesting devices
From wearable technology to industrial heat recovery, thermoelectric generators which convert waste heat into electricity have an enormous range of potential applications. So far, however, designing high-performing versions ...
