Genetic Background Influences Cancer Risk of Thirdhand Smoke Exposure

June 7, 2023

A new study investigating the effect of thirdhand smoke (THS) in a mouse model system specially designed to mimic the genetic diversity of human populations has shed new light on how genetic predispositions contribute to an individual’s cancer risk.

Machine Learning Helps Link Chemical Exposure and Obesity

May 1, 2023

Scientists at Berkeley Lab and their collaborators developed a machine learning technique to discover obesity-related mixed chemical exposure patterns associated with environmental health risk in the general U.S. population. To assess this, they used indicators like body mass index and waist circumference.

Thirdhand Smoke Harms the Body More Than We Ever Realized

August 17, 2022

A new study found that concentrations of toxic chemicals lingering indoors where cigarettes have been smoked can exceed risk guidelines from the State of California. This means that non-smokers can be exposed to health risks by living in contaminated spaces.

Microbes to the Rescue

April 4, 2022

Three fruit flies.

A team of researchers from the Biosciences Area at Berkeley Lab and the University of Birmingham in the United Kingdom found one particular organism in the fly’s microbiome that helps protect it from atrazine, an herbicide toxic to flies that is commonly used in agriculture. This method of rescuing fruit flies from atrazine poisoning with probiotics may be useful for protecting pollinators in agriculture.

A Laser-powered Upgrade to Cancer Treatment

Researchers in the Biological Systems and Engineering (BSE) Division are collaborating with colleagues at the Berkeley Lab Laser Accelerator (BELLA) Center to adapt the nascent technology of laser-driven ion accelerators to make a more effective type of radiation more readily available to patients. The mutually beneficial partnership gives BELLA scientists a real-world application around which to refine their experimental laser platform, and gives the biologists a chance to test how living tissue responds to laser-driven proton beams at FLASH dose rates.
