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.

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.
The American Society of Chemistry (ACS) has announced Naomi S. Ginsberg is a recipient of the 2020 early-career award in experimental physical chemistry. She is being recognized "For the development of new time- and space-resolved imaging and spectroscopy methods to study dynamical phenomena in heterogeneous materials". The Physical Chemistry Division of ACS annually sponsors senior and early-career awards in theoretical and experimental physical chemistry that are intended to recognize the most outstanding scientific achievements of members of the Division. The recipients will be honored at the the Fall ACS National Meeting in San Francisco.
Scientists in the lab of Kevin Wilson (Ph.D. '03, Chem), at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have made a surprising discovery that could help explain our risk for developing chronic diseases or cancers as we get older, and how our food decomposes over time. What’s more, their findings, which were reported recently in the Proceedings of the National Academy of Sciences (PNAS), point to an unexpected link between the ozone chemistry in our atmosphere and our cells’ hardwired ability to ward off disease.

In honor of Engineers Week, Aerospace Corporation is spotlighting a few of our many great engineers and getting a peek at the exciting projects that they’re focused on. Find out about Yao (B.S. '08, Chem) wound up at the Aerospace Corporation doing exciting work in photovoltaic characterization and solar array modeling.
As we push the Periodic Table of the Elements further and further into the unknown, its familiar columns and rows are threatening to crumble. What’s next for this science icon? Superheavy elements exist for a fraction of time and are nearly impossible to catch. But understanding them could force us to reimagine the most iconic scientific symbol of all time..
Adsorption is a process which plucks water molecules from air that has less than 100% relative humidity by attaching them to the surface of a solid material. The molecules are held there by electrostatic connections called Van der Waals forces that link them with the molecules of the pertinent surface. To collect a lot of water this way therefore requires a material that has two properties. One is a large surface area. The other is an appropriate Van der Waals response. Experimental traps that employ this principle have been made using substances called metal-organic frameworks.

Scientists have discovered hundreds of unusually large, bacteria-killing viruses with capabilities normally associated with living organisms, blurring the line between living microbes and viral machines as reported in new research findings in Nature. These phages — short for bacteriophages, so-called because they “eat” bacteria — are of a size and complexity considered typical of life, carry numerous genes normally found in bacteria and use these genes against their bacterial hosts.
On the brink of his 100th trip around the sun, the secret to David Altman’s (Ph.D. '43, Chem) long and illustrious life isn’t rocket science. At least, not entirely. It’s a strategy that seems to have worked well for Altman, who will officially become a centenarian on Thursday. His dizzying number of accomplishments in rocket science — papers written, patents held, awards won — seem to indicate that not a moment was wasted in all of his one hundred years.

UC Berkeley is not just one of the best research universities in the world, but also a unique place for entrepreneurs, students and alumni to grow and build their own innovative startups. Many of the ideas are based on issues young entrepreneurs first encountered in Berkeley classes or labs. Two College of Chemistry startups presented among 23 young companies last week at Berkeley SkyDeck’s annual Demo Day, where entrepreneurs pitched new devices, apps or inventions that, they hope, will provide big, bold fixes to the world’s problems, from climate change to disease.

An injection of cash helped the University of California, Berkeley, reform its general chemistry lab instruction. Back in 2012, the College of Chemistry received a gift of money from the Dow Chemical Company Foundation. Most of the funds were used to completely renovate the teaching labs, adding new equipment and modern instrumentation. But, says Anne M. Baranger, UC Berkeley’s director of undergraduate chemistry, $1 million was earmarked for developing a new teaching curriculum to match the labs. And the focus was on sustainability.
Alexis Bell, The Dow Professor of Sustainable Chemistry at Berkeley and Frances Arnold, Linus Pauling Professor of Chemical Engineering, Bioengineering and Biochemistry, and an alumna of the College were both cited on the list of catalysis pioneers listed in the ACS publication ACS Axial.

Eric Seaborg, a writer and author, outdoorsman and environmentalist, has a love for hiking that he shared with his father, the late chemist and Nobel laureate Glenn Seaborg (1912-1999) who blazed trails in element and isotope discoveries during an illustrious career at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley.

Polly Arnold is a champion of actinide chemistry and diversity in science. Kit Chapman asks her what comes next as she starts her new role at a US national lab
‘Do I have imposter syndrome?’ Polly Arnold raises an eyebrow at the question, as if it’s the most obvious thing in the world. ‘Yes, of course I do. Everybody who didn’t go to Eton has imposter syndrome. Not just the women, it’s the men who didn’t go to a brilliant school, too. The only people who don’t have imposter syndrome are those told from childhood they’re born to rule.’
Jennifer Doudna, UC Berkeley professor of molecular and cell biology and of chemistry, has won the 2020 Wolf Prize in Medicine, a prestigious international prize awarded in Israel for unique contributions to humanity.
