Outside-In Signaling Shows a Route Into Cancer Cells

Andy Fell — February 04, 2025 - 9:08am

A new study shows how an anticancer drug triggers an “outside in” signal that gets it sucked into a cancer cell. The work, published Jan. 29 in Nature Communications, reveals a new signaling mechanism that could be exploited for delivering other drugs.

Many malignant cancers overexpress a protein called P-cadherin, which is embedded in the cell membrane. Because cancer cells have a lot of P-cadherin sticking out of their surface, the protein has been targeted for drug development.

Long-Term Study on Health Impacts of Los Angeles Wildfires Launched

Katherine E Kerlin — January 31, 2025 - 12:10pm

In an unprecedented collective scientific effort to understand the short- and long-term health impacts of wildfires, researchers from four universities have launched a 10-year study of the Los Angeles fires. The wildfires that began in early January 2025 killed 29 people, destroyed more than 16,000 structures, and exposed millions to toxic smoke.

The research aims to evaluate which pollutants are present, at what levels, and where, and to assess the respiratory, neurological, cardiovascular, reproductive, and immune system impacts of the wildfires.

Creating Nanoislands for Better Platinum Catalysts

Andy Fell — January 28, 2025 - 4:27pm

Noble metals such as platinum can make useful catalysts to accelerate chemical reactions, particularly hydrogenation (adding hydrogen atoms to a molecule). The research team led by Professor Bruce Gates at the UC Davis Department of Chemical Engineering is interested in making platinum catalysts that are highly efficient and stable during chemical reactions.

New Angle Etching Technique for Making Quantum Devices

Andy Fell — January 24, 2025 - 4:40pm

Researchers at the University of California, Davis, have demonstrated an angle etching method for fabricating quantum photonic devices at the wafer scale in silicon carbide.

Color centers are the essential hub for photons (particles of light) in quantum devices. They are the components that emit and maintain photons, functioning as a quantum memory bank. However, they are challenging to fabricate, particularly for the industrial development of quantum technology.

Wrong Place, Wrong Time: Why Zika Virus Hijacks a Protein Needed for Brain Growth

Andy Fell — January 13, 2025 - 11:13am

The mosquito-borne Zika virus is known for causing microcephaly, a birth defect in which abnormal brain development results in a smaller-than-expected head. A new study published Jan. 13 in mBio shows that the Zika virus hijacks a host protein called ANKLE2, which happens to be important for brain development, to assist its own reproduction. Because Zika, unlike most related viruses, can cross the placenta, this can have disastrous consequences in pregnancy.

Storing Carbon in Buildings Could Help Address Climate Change

Andy Fell — January 09, 2025 - 6:08pm

Construction materials such as concrete and plastic have the potential to lock away billions of tons of carbon dioxide, according to a new study by civil engineers and earth systems scientists at the University of California, Davis and Stanford University. The study, published Jan. 10 in Science, shows that combined with steps to decarbonize the economy, storing CO2 in buildings could help the world achieve goals for reducing greenhouse gas emissions.

Your Smart TV is Watching What You Watch

Andy Fell — December 18, 2024 - 2:45pm

If you’re thinking of buying a “smart” TV for the holidays, you ought to know that your new device is constantly capturing snapshots of what’s on screen and sending them back to the manufacturer — even if you are using the device as a computer monitor and not watching TV at all. The findings come from a recent study by computer scientists at the University of California, Davis; University College London; and Universidad Carlos III de Madrid, published in Proceedings of the 2024 ACM on Internet Measurement Conference.

UC Davis Joins New $285 Million CHIPS Semiconductor Research Institute

Andy Fell — December 09, 2024 - 4:40pm

The University of California, Davis will be part of a new, $285 million nationwide institute dedicated to advancing research and manufacturing of American semiconductors.

The new institute, known as SMART USA (Semiconductor Manufacturing and Advanced Research with Twins USA) will develop, validate and use digital twins to improve domestic semiconductor design, manufacturing, advanced packaging, assembly and test processes.

A Chip to Measure Immunity

Andy Fell — December 04, 2024 - 4:16pm

Every winter, influenza returns with a new variant. People who have previously been infected with or vaccinated against flu may have some protection, but this depends on how well their immune system’s “memory” of the previous virus or vaccine cross-reacts with the new variant. At present, there is no good way to measure this. A new NIH-funded project by researchers at the University of California, Davis and Johns Hopkins Bloomberg School of Public Health aims to solve that problem with a new device to measure this immune system “memory” in the blood.

Eye, Robot: Researchers Give Machines a New Perspective with Active Vision

Andy Fell — November 26, 2024 - 2:46pm

When Iman Soltani worked in the automotive industry, he studied assembly floors and noticed that each automated task had its specific robotic design.

He also noticed that while a robot would need multiple cameras affixed to several locations for the best possible sightline, an operator on the assembly floor would move their head and neck to get the best view as they manipulated components.
