Based on the precise measurements reported in this study, researchers hypothesized what mixtures of bulk ingredients could give the TRAPPIST-1 planets their densities, offering the most precise picture of exoplanet composition achieved to date.
With the third week of winter quarter underway at the University of California San Diego, COVID-19 case rates have fallen dramatically since classes resumed on Jan. 4. The current test positivity rate on campus has reduced to pre-break levels of less than 1%.
As mandates prevented gatherings over the holiday season, crowds in Chile and Argentina donned masks and eye shields to view some a two-minute solar eclipse on December 14. A week before, researchers at PSI used SDSC's Expanse supercomputer to see how closely they could simulate the event.
As the waters off our coasts change due to human influences, scientists have found that the composition of shells of California mussels, a critical species found along the Pacific Coast, are weakening as a result of ocean acidification.
UC San Diego chemistry researchers find that the smallest fresh sea spray particles become 100,000 times more acidic than the ocean within two minutes.
Biologists have unraveled the mystery of how chromosomes are inherited correctly every time a cell divides. They discovered how a “matchmaker” molecule stops cell division until components are ready to be split. Alterations in the process can result in birth defects and certain cancers.
Simulations conducted using the Comet supercomputer at UC San Diego's San Diego Supercomputer Center provide new insights on how chloride corrodes structural metals, causing severe economic and environmental impacts.
This wasn’t Noah’s flood. But it was still a catastrophic event that profoundly changed the landscape and could have given rise to legends, too. Study identifies oldest known paleo tsunami in the Eastern Mediterranean.
New simulations done on supercomputers may help researchers understand how these inhibitors react and potentially help to develop a new generation of drugs to target viruses with high death rates including SARS-CoV2, the virus that causes COVID-19.
A broad coalition that includes UC San Diego scientists sets commitments for field trials of powerful gene drive technology. The multidisciplinary group encourages trials that are safe, transparent and ethical.
