First ‘Telomere to Telomere’ Human Genome Reveals Secrets of the Centromere

Adapted from a news release by Robert Sanders When scientists announced the complete sequence of the human genome in 2003, they were fudging a bit. In fact, nearly 20 years later, about 8% of the genome has never been fully sequenced, largely because it consists of highly repetitive chunks of DNA that are hard to

Efficient and Healthy Schools Campaign Focuses On Indoor Air Quality

A new campaign, Efficient and Healthy Schools, led by Berkeley Lab will provide practical guidance on ventilation upgrades that can increase energy efficiency, lower costs, and improve the air at K-12 schools nationwide.

Safely Studying Dangerous Infections Just Got a Lot Easier

Soft X-ray tomography – a way to take gorgeously high-resolution, 3D images of cells – can help us study infections without risk of contamination. And now, the whole process takes just a fraction of the time and preparation required by other imaging methods.

Cell ‘Fingerprinting’ Could Yield Long-Awaited Alzheimer’s Disease Diagnostic

A new process combining infrared light analysis and machine learning shows potential to break barriers in disease detection.

Poorly Circulated Room Air Raises Potential Exposure to Contaminants by up to 6 Times

Having good room ventilation to dilute and disperse indoor air pollutants has long been recognized, and with the COVID-19 pandemic its importance has become all the more heightened. But new experiments by Berkeley Lab indoor air researchers show that certain circumstances will result in poor mixing of room air, meaning airborne contaminants may not be effectively dispersed and removed by building level ventilation.

Empowering a Neighborhood to Breathe Easy

Companies like Purple Air and IQAir, with air pollution sensors that cost under $300, have brought air quality monitoring to the masses. But when Lawrence Berkeley National Laboratory scientist Tom Kirchstetter looked at Purple Air’s map last year during wildfire season, he noticed a big hole in Richmond, a city of 110,000 to the north of Berkeley.

Are Heavy Metals Toxic? Scientists Find Surprising New Clues in Yeast

Scientists at Berkeley Lab and UC Berkeley have compiled the most complete library yet of lanthanide heavy metals and their potential toxicity – by exposing baker’s yeast to lanthanides. Their findings could help researchers uncover hidden pathways between lanthanide metals and disease.

Emissions from Vaporizable Cannabis Concentrates Have Potential Health Risks

As more U.S. states and countries legalize medical and recreational marijuana, consumers are increasingly turning to new types of products that avoid toxic smoke inhalation. Researchers at Berkeley Lab who previously identified potentially harmful emissions from electronic cigarettes are now identifying the potential health risks of vaping cannabis.

How X-Rays Could Make Reliable, Rapid COVID-19 Tests a Reality

Vaccines are turning the tide in the pandemic, but the risk of infection is still present. Instant at-home tests would help us return to normal, but current options aren’t very accurate. A new discovery could help get reliable tests on the market.

New Cuff-Based Technology Monitors Endothelial Function to Aid Prevention, Treatment of Heart Disease

Berkeley Lab has developed a cuff-based technology to monitor both endothelial function and endothelium-independent vasodilation. Studies on human subjects have verified that the cuff-based method is 37% more sensitive to arterial relaxation than brachial artery imaging.
