Coronavirus impact: Maps show pollution has dropped in the Bay Area since shelter-in-place orders

pollution drops in Bay Area

BERKELEY, Calif. (KGO) -- A single image helped alert the world to a once-in-a-lifetime side effect of the COVID-19 crisis. It was a satellite map, showing a dramatic drop in pollution levels over China after the country began to effectively quarantine its population. Shortly afterward Ron Cohen, Professor of Chemistry and of Earth and Planetary Sciences at UC Berkeley, predicted a similar effect here in the Bay Area.

International group of researchers race to find treatment for COVID-19

scientists look for COVID-19 treatment

UC Berkeley and UCSF Professor Kevan Shokat, along with members of his lab, have joined with other scientists around the world in a unique research project under the auspices of the Quantitative Biosciences Institute Coronavirus Research Group (QBI) spearheaded by UCSF Professor Nevan Krogan. The international team is testing an unusual new approach to identify potential antiviral drugs with proven efficacy to treat SARS-Cov-2 infections. Given the world crisis, the strategy of testing known/approved drugs could help reduce the numbers of deaths in the near term while the world health community battles the epidemic.

World air quality is improving as people stay home

Bay Area air quality improves as people forced to stay home

Fewer vehicles on the road and the slowing world economy has lead to blue skies over the world including the Bay Area, China, and Italy. Locally, every day since March 14, the EPA Air Quality Index has reported all nine Bay Area counties bathed in green on its color scale, for good quality air. It’s rare to have so many consecutive clean-air days. And last week, air-quality sensors that measure particulate matter showed the lowest average readings of any week so far in 2020 — down 21% in Oakland, 36% in San Jose and 41% in San Francisco from the week before.

'Human Nature': film review

film review of 'Human Nature

How many newspaper stories, magazine features and TV segments have been produced so far that marvel at the revolutionary capabilities of CRISPR while giving almost no idea at all how the gene-editing discovery actually works? Those who lament the state of science journalism should take note of 'Human Nature', in which Adam Bolt and helpful scientists offer an easily understood introduction to techniques often described with head-scratching phrases like "it's a word processor for DNA!" A cogent, wide-ranging look at both the discovery and the nascent, soon-to-be-giant fights humans are having over it, the documentary should be welcomed in its limited theatrical release and will be even more useful on video.

The power of change in science

women trailblazers

Guided by CRISPR pioneer Jennifer Doudna, a formidable entrepreneur in her own right, C&EN profiled 15 women working in the Chemical industry in academics and startups in C&EN's 2020 Trailblazers. Four of them are affiliated with UC Berkeley's College of Chemistry. They have collectively launched more than 30 start-ups aimed at developing treatments for rare diseases, building better batteries, and more. They’re chemical scientists at the top of their game. They’re role models building and mentoring teams. And yes, they’re badasses. They live by the motto “Nobody ever got anywhere by listening to no.”

New discovery facilitates design of synthetic proteins

January 9, 2020

synthetic film that mimics transmembrane proteins

Researchers, led by UC Berkeley lead investigator Ting Xu, Professor of Chemistry & Materials Science and Engineering, have created a synthetic material that is as effective as naturally occurring proteins in transporting molecules through membranes, a major milestone that could transform such fields as medicine, life sciences, alternative energy and environmental science.

Novel synthetic proteins rival their natural counterparts in proton transport

polymer membranes

Biological membranes, such as the "walls" of most types of living cells, primarily consist of a double layer of lipids, or "lipid bilayer," that forms the structure, and a variety of embedded and attached proteins with highly specialized functions, including proteins that rapidly and selectively transport ions and molecules in and out of the cell. Scientists have long sought to develop synthetic membranes that could match the selectivity and high-speed transport offered by their natural counterparts. Now a team led by University of California Berkeley researchers has designed a novel polymer that is as effective as natural proteins in transporting protons through a membrane. The results of their research were published in Nature.

Scientists Bring Polymers Into Atomic-Scale Focus

From water bottles and food containers to toys and tubing, many modern materials are made of plastics. And while we produce about 110 million tons per year of synthetic polymers like polyethylene and polypropylene worldwide for these plastic products, there are still mysteries about polymers at the atomic scale.

Learn about food packaging from this green chemist

Wondering which plastic containers to avoid and which are safe to eat from? How to learn about chemicals in food packaging? Or how to make sure you are buying BPA-free foods? Foodprint recently held a Twitter chat with Dr. Martin Mulvihill (Ph.D. ’09, Chem), researcher and advisor at the Berkeley Center for Green Chemistry and general partner with Safer Made, a mission-driven venture capital fund that invests in companies that remove or reduce the use of harmful chemicals in products and manufacturing processes and asked that very question.

Jean Fréchet awarded Charles Stark Draper Prize for Engineering

Jean Fréchet and C. Grant Willson

The National Academy of Engineering has announced today that the 2020 Charles Stark Draper Prize for Engineering will be awarded to Jean Fréchet, Professor Emeritus of Chemistry at UC Berkeley and C. Grant Willson, Professor Emeritus at UT Austin “for the invention, development, and commercialization of chemically amplified materials for micro- and nanofabrication, enabling the extreme miniaturization of microelectronic devices.”
