The gut microbiome undergoes rapid and dramatic changes in species composition and gene expression when the host switches between eating cooked or raw vegetables, according to a new study published in Nature Microbiology.
Marketed as a healthier alternative to cigarettes, a new class of tobacco products called heat-not-burn devices is quickly gaining in popularity across the globe. A study by Berkeley Lab’s Indoor Environment Group shows that, although the chemical emissions from these devices are lower than those produced by conventional cigarettes, they are still high enough to raise concern.
A new study by researchers at Lawrence Berkeley National Laboratory shows that if every building in California sported “cool” roofs by 2050, these roofs would help contribute to protecting urbanites from the consequences of dangerous heatwaves.
Researchers at Lawrence Berkeley National Laboratory have developed a new chemical separation method that is vastly more efficient than conventional processes, opening the door to faster discovery of new elements, easier nuclear fuel reprocessing, and, most tantalizing, a better way to attain actinium-225, a promising therapeutic isotope for cancer treatment.
Researchers in Berkeley Lab’s Computational Research Division are applying deep learning and analytics to electronic health record (EHR) data to help the Veterans Administration address a host of medical and psychological challenges affecting many of the nation’s 700,000 military veterans.
A human’s health is shaped both by environmental factors and the body’s interactions with the microbiome, particularly in the gut. Genome sequences are critical for characterizing individual microbes and understanding their functional roles. However, previous studies have estimated that only 50 percent of species in the gut microbiome have a sequenced genome, in part because many species have not yet been cultivated for study.
Berkeley Lab indoor air experts Brett Singer and Woody Delp advise: stay indoors, consider a mask, limit activities, use air filtration systems, or even build your own.
A research team has demonstrated how light-emitting nanoparticles, developed at Berkeley Lab, can be used to see deep in living tissue. Researchers hope they can be made to attach to specific components of cells to serve in an advanced imaging system that can pinpoint even single cancer cells.
An international team led by scientists at Berkeley Lab and UC Berkeley discovered how to exploit defects in nanoscale and microscale diamonds and potentially enhance the sensitivity of magnetic resonance imaging and nuclear magnetic resonance systems while eliminating the need for their costly and bulky superconducting magnets.
Researchers at Berkeley Lab identified thirdhand smoke, the toxic residues that linger on indoor surfaces and in dust long after a cigarette has been extinguished, as a health hazard nearly 10 years ago. Now a new study has found that it also increases lung cancer risk in mice.
