Gene that makes large, plump tomatoes identified
Farmers can grow big, juicy tomatoes thanks to a mutation in the cell size regulator gene that occurred during the tomato domestication process.
Engineering team images tiny quasicrystals as they form
What makes quasicrystals so interesting? Their unusual structure. Now scientists are actively pursuing this relatively new area of study.
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?...
Australia’s ghost crabs decapitate baby sea turtles
Life can get off to a rough start for loggerhead sea turtle (Caretta caretta) hatchlings. In fact, it can look more like a feeding frenzy with the sea turtles as the featured...
Orange male guppies are hornier
For guppies (Poecilia reticulata) getting ready to mate, the color orange speaks volumes. The more orange coloration on a male guppy, the more virile it is, according to a study recently published...
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...
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
Scientists have discovered a common mutation that might explain why some people have trouble going to sleep at night and getting up early. The gene alteration slows the internal biological...
Scientists discover how crucial DNA sequences endure
The centromere region of chromosomes retains the same DNA from one generation to the next. Scientists have gained new insights into how it avoids being scrambled in normal cells, and...
Researchers track fish migration by testing DNA in seawater
For the first time, researchers have successfully recorded fish migration by conducting DNA tests on water samples. Using this method to estimate the abundance and distribution of fish species could...
Shooting the messenger: how one protein allows germ cells to develop
Researchers have identified a molecule that guides the formation of eggs and sperm by preventing a host of factors related to cell death and inflammation from killing the precursors to...
Scientists engineer human-germ hybrid molecules to attack drug-resistant bacteria
Taking a cue from viruses that infect and kill bacteria, the researchers engineered molecules capable of targeting the bugs in a way the human immune system cannot—an approach that could...
Climate change could separate vanilla plants and their pollinators
The vanilla species grown for its flavoring is finicky. Genes from its wild relatives could help make it hardier — but not if those cousins go extinct.
Scientists 3-D printed a tiny elephant inside a cell
The first structures ever 3-D printed inside living cells point to applications for biology research.
Why these zombie caterpillars can’t stop eating
Sneaky chemistry by a real-life “Last of Us” Cordyceps fungus mind controls its zombie insect victims by convincing them they’re starving.
These 5 nutrients might be lacking in your diet
U.S. diets should include more of vitamins D and E, fiber, calcium and magnesium — all are essential nutrients that could offer health benefits.
Simulations reveal how sharp boundaries endure in soft tissue
Research could help explain how cells organize into complex living systems
