Researchers identified a specialized protein that catalyzes conformational change of mitotic proteins, allowing correct exit from mitosis. This finding has significant implications for understanding and developing anti-cancer agents targeting this mechanism.
Researchers have crystallized the active form of adenylyl cyclase, revealing how Gs-alpha binds to and activates it. This discovery helps understand the regulation of these enzymes, which are crucial for various biochemical processes.
Research by Stanford University finds that L.A. smog's filtering effect reduces both UV radiation and ozone levels, benefiting skin cancer prevention and respiratory health. The study identifies specific chemical compounds in smog as responsible for this phenomenon.
A University of Michigan model reveals that carbon and sulfur emissions can cool the planet by up to -4.4 Wm-2, potentially offsetting human-caused warming. However, the models' uncertainty due to poorly known estimates for natural aerosol sources may limit the findings.
Geologist Professor Joseph Smyth discovered wadsleyite can contain solid water bound in crystals at extreme pressures. The earth's interior may store large amounts of water in the form of wadsleyite, which could regulate surface water levels. Laboratory tests are underway to determine the amount of water in wadsleyite.
The American Institute of Physics announces a new award for broadcast media, recognizing distinguished writing that improves public understanding of physics and astronomy. The winning author will receive $3,000 and a certificate.
A team of scientists discovered that the Pioneer 10 spacecraft detected a radio signal modulation mimicking a planet's orbit around PSR B1257+12. The analysis reveals that solar rotation causes similar variations in the pulsar's radio waves, effectively simulating the planet.
Researchers at Fritz Haber Institute use scanning tunneling microscope to investigate CO oxidation reaction, revealing surface oxygen atoms and molecules form islands that separate into reactive species. The study determines reaction rates with island separation accounted for, consistent with previously measured values.
