Is it really Lyme? Researchers developing a new test to tell
WASHINGTON (AP) -- Diagnosing if a tick bite caused Lyme or another disease can be difficult but scientists are developing a new way...
Science Says: DNA test results may not change health habits
NEW YORK (AP) -- If you learned your DNA made you more susceptible to getting a disease, wouldn't you work to stay healthy?...
In some genetic cases of microcephaly, stem cells fail to launch
In a very severe, genetic form of microcephaly, stem cells in the brain fail to divide, according to a new Columbia University Medical Center study that may provide important clues...
Purest yet liver-like cells generated from induced pluripotent stem cells
This image shows induced pluripotent stem cells expressing a characteristic cell surface protein called SSEA4 (green). A research team including developmental biologist Stephen A. Duncan, D. Phil., SmartStateTM Chair...
Study finds shark fins & meat contain high levels of neurotoxins linked to Alzheimer's disease
Cyanobacterial neurotoxin β-N-methylamino-L-alanine (BMAA) and Mercury are detected in sharks from the Atlantic and Pacific Oceans. In a new study, University of Miami (UM) scientists found high concentrations of...
More tomatoes, faster: Accelerating tomato engineering
A researcher transfers tomato plantlets from a plate of regeneration medium. Tomatoes are already an ideal model species for plant research, but scientists at the Boyce Thompson Institute (BTI)...
New genus of bacteria found living inside hydraulic fracturing wells
Ohio State University researchers and their colleagues have identified a new genus of bacteria living inside hydraulic fracturing wells. Researchers analyzing the genomes of microorganisms living in shale oil...
Brain circuit that drives sleep-wake states, sleep-preparation behavior is identified
Stanford University School of Medicine scientists have identified a brain circuit that's indispensable to the sleep-wake cycle. This same circuit is also a key component of the reward system, an...
Giraffes more speciose than expected
Scientists from the Senckenberg and the Giraffe Conservation Foundation have analysed the genetic relationships of all major populations of giraffe in the wild. The large study on the genetic makeup...
Study reveals how ionising radiation damages DNA and causes cancer
For the first time, researchers from the Wellcome Trust Sanger Institute and their collaborators have been able to identify in human cancers two characteristic patterns of DNA damage caused by...
The proteins that domesticated our genomes
EPFL scientists have carried out a genomic and evolutionary study of a large and enigmatic family of human proteins, to demonstrate that it is responsible for harnessing the millions of...
Don't Feed the Animals: Researchers Warn of Risks Tied to Wildlife Interactions
A study led by a UC San Diego scientist offers new warnings on the dangers of human interactions with wildlife. The new report, which focuses on elephants, indicates that human...

Theory for Aerosol Droplets From Contaminated Bubbles Bursting Gives Insight Into Spread of Pollution, Microplastics, Infectious Disease
A systematic study of aerosol jets from contaminated bubbles bursting has resulted in a theoretical model predicting the influence of contaminants on spray size, illustrating an important mechanism for airborne...
A Molecule that Seeks Out Forever Chemicals in Water
PFAS are ubiquitous substances with an insidious name: forever chemicals. Recently, numerous variants of perfluoroalkyl and polyfluoroalkyl substances (PFAS) have been detected throughout the environment, including in the blood of...
Are salmon sperm facials really good for your skin?
Med spas all over Los Angeles now offer what they call salmon DNA facials. Does the trendy social media-approved treatment actually work?
Called to the threshold, a death doula learns from the dying
Transitions and transformations can be fraught, even torturous. As a death doula, a big part of the work is sitting in that liminal space.
Inside Nike's all-women half-marathon in L.A.: the good, the bad and the surprising

What is a mushroom really? Two titans of the wellness world duke it out
Paul Stamets and Jeff Chilton began as friends, their collaboration leading to the rise of medicinal mushroom supplements. Until they disagreed on one important thing: the definition of mushroom.
Measles on the rise in California: More cases so far this year than all of 2024
California has already reported more measles cases this year than in all of 2024, a worrisome development that comes as the nation is suffering its largest outbreak of the super-infectious...
For biologists studying tiny worms, new technologies make big improvements
Two new technologies are helping scientists understand new aspects of organ and nervous system development in C. elegans. One allows them to image worms developing in a natural environment, while...
New study resolves the structure of the human protein that causes cystic fibrosis
In order to better understand how genetic mutations give rise to cystic fibrosis, researchers need to map the protein responsible for the disorder. The new structure has led to new...
For microbes fighting viruses, a fast response means a better defense
Researchers have found that the bacterial immune system targets an invading virus as soon as it enters the cell. This discovery answers a long-standing question about how microbes defend themselves....
Study identifies “night owl” gene variant
