Pulsed-electron illumination does not reduce beam damage for imaging biological macromolecules
Abstract Radiation damage remains a fundamental limitation in cryo-electron microscopy (cryo-EM), constraining the total electron dose that can be used and thus limiting high-resolution imaging of biological specimens. Recent studies have proposed that temporally structured or pulsed electron beams could reduce radiation damage by allowing time for energy dissipation between individual electron interactions.
Trump Administration Announces Tariffs on Imported Patented Medication and Pharmaceutical Ingredients under Section 232 of the Trade Expansion Act of 1962
On April 2, 2026, exactly one year after the “Liberation Day” tariffs, President Donald Trump issued a Proclamation, “Adjusting Imports of Pharmaceuticals and Pharmaceutical Ingredients into the United States,” (the “Proclamation”) imposing sweeping tariffs on imported patented medications and active pharmaceutical ingredients (“APIs”).
Fundamental Research, National Security, And The Quiet Shift Facing Universities
Aiysha Hussain’s articles from Mayer Brown are most popular: within International Law topic(s) in United States Universities and research institutes have long relied on the protections for "fundamental research" under national security laws to enable international collaboration in open science.
Fundamental Research, National Security, and the Quiet Shift Facing Universities | JD Supra
Universities and research institutes have long relied on the protections for “fundamental research” under national security laws to enable international collaboration in open science. Through provisions dating back to the height of the Cold War, basic and applied research has been carved out of restrictions on the transfer of intangible technology to foreign nationals (known as “deemed exports”).
Administration Policies On Advanced AI Chips Codified, With Reverberations Across AI Ecosystem
Commerce rule eases licensing for advanced AI chips to China and establishes new criteria for license applications; Presidential Proclamation imposes 25% tariff on covered advanced chip imports when intended for any customer outside United States In the last week, the Trump Administration has taken several actions to formalize policies enabling the export of advanced AI semiconductor chips to China and PRC companies. Each measure has repercussions across the AI ecosystem.
House Enacts the Senate Legislative Text of the One Big Beautiful Bill Act | JD Supra

Letter: Stop tainting the name of Alta Heights
Alta Heights is a wonderful place to live and raise a family in Napa. My wife and I have lived in Alta Heights for 30 years and raised our children and grandchildren in Napa. I've always been proud of what Alta Heights contributes to the city; it has always been a place where we welcomed new neighbors and looked out for each other’s needs.
Letter: City needs to do more to improve walking and bicycling safety
Over the past years we have made great strides in providing the citizens of Napa safer streets. Through community action and coalitions many changes have taken place to make walking and bicycling less dangerous and more comfortable. Unfortunately the city seems to implement improvements in a manner that is not consistent to standards followed by other cities. One example is the bike lane along Freeway Drive adjacent to the Outlets.
Light Color‐Controlled pH‐Adjustment of Aqueous Solutions Using Engineered Proteoliposomes
1 Introduction Bottom-up synthetic biology combines building blocks from nature and engineered versions thereof to new functional molecular systems and aims at their application in basic research, biotechnology, and medicine.[1] Microbial rhodopsin proton pumps are membrane proteins that use light to translocate protons generally from the intracellular to the extracellular side of the plasma membrane, thereby powering the proton motive force of the cell.[2] Thus, such light-driven proton...
