"A 25-year-old J. Robert Oppenheimer arrived at UC Berkeley in fall 1929 as an assistant professor, and over the next dozen years established one of the greatest schools of theoretical physics in the U.S. — one that continues to this day. He made UC Berkeley’s physics department the center of American thought about the new field of quantum mechanics and how to apply it to atoms, nuclei and even neutron stars."  

"A new study suggests that cells preparing to divide can reverse this process and return to a resting state, challenging long-held beliefs about cell division. If interrupted early in their preparation to divide, cells were able to halt the division process, known as mitosis. The finding, led by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and reported July 5, 2023, in Nature, could point toward more effective treatments to interrupt the process by which cancer cells divide quickly and spread. Finding  could point toward more effective treatments that could potentially prevent cancer relapse."

I had to clean out a cupboard to find storage space, but by the time the jars and tubes were stowed away, my equanimity had returned. They lie there untouched, and my wrinkles deepen. I'm working on turning them into smile lines."   

"From the Editor: We've tried to replicate parts of the CDC Center for Disease Control and Prevention's presentation of their Drowning Prevention information but urge you to go to their pages in effort to gain a organized way to compile as much information as you can. Tam Martinides Gray, Editor '...Drowning is a serious public health problem. Drowning can happen in seconds and is often silent. It can lead to long-term disability. Drowning is preventable... The Lifesaving Society designates the third week in July (July 16-22, 2023) as National Drowning Prevention Week (NDPW) to focus community and media attention on the drowning problem and drowning prevention.'"

Abstract: While the descriptive impacts of the pandemic on women have been well documented in the aggregate, we know much less about the impacts of the pandemic on different groups of women. After controlling for detailed job and demographic characteristics, including occupation and industry, we find that the pandemic led to significant excess labor force exits among women living with children under age six relative to women without children. We also find evidence of larger increases in exits among lower-earning women. The presence of children predicted larger increases in exits during the pandemic among Latina and Black women relative to White women. Overall, we find evidence that pandemic induced disruptions to childcare, including informal care from family and friends. Our results suggest that the unique effect of childcare disruptions during the pandemic exacerbated pre-existing racial and income inequalities among women.

IR-2023-123, July 3, 2023 WASHINGTON ― The Internal Revenue Service warned taxpayers today to be on the lookout for a new scam mailing that tries to mislead people into believing they are owed a refund. The new scheme involves a mailing coming in a cardboard envelope from a delivery service. The enclosed letter includes the IRS masthead and wording that the notice is“in relation to your unclaimed refund.” Like many scams, the letter includes contact information and a phone number that do not belong to the IRS. But it also seeks a variety of sensitive personal information from taxpayers – including detailed pictures of driver’s licenses – that can be used to by identity thieves to try obtaining a tax refund and other sensitive financial information. 8:09 AM (1 hour ago)     Reply to me       IRS Newswire July 03, 2023 News Essentials…

Rose Madeline Mula Writes: "I haven’t been inside a store for two years. I don’t miss any of them. Not a bit. I am delighted to have Instacart deliver my groceries — and Amazon everything else I could possibly want — to my door on demand, without having to navigate aisle after aisle searching for a mango, or that foot callus file I always wanted but could never find. It’s like having my own Aladdin’s lamp! Most of my neighbors in my condo building have mats at their doors that are truly welcoming. They say “So glad you’re here!” or “Welcome! Come in and cozy up!” Mine says “Oh, no! Not you again!” (I don’t mean it, of course; but I can never resist humor.)"

“Observing changes in Earth’s rotational pole is useful for understanding continent-scale water storage variations,” said Ki-Weon Seo, a geophysicist at Seoul National University who led the study. Seo said. “Polar motion data are available from as early as the late 19th century. So, we can potentially use those data to understand continental water storage variations during the last 100 years. Were there any hydrological regime changes resulting from the warming climate? Polar motion could hold the answer.” “I’m very glad to find the unexplained cause of the rotation pole drift,” Seo said. “On the other hand, as a resident of Earth and a father, I’m concerned and surprised to see that pumping groundwater is another source of sea-level rise.”
