U of MN researchers develop way to visualize synchronized interactions of nerve cells in the brain

... groups of active brain cells operate and interact simultaneously with each other in different parts of the brain. ...

Sociality of sweat bees evolved simultaneously during climate change

...ial behavior of many species of sweat bees evolved simultaneously during a period of global warming. This social evolution occurred much more recently than scientists ever thought -- only 20 million to 22 million years ago, compared with the social evolution of other insects, which evolved more than 65 million ye...

A Jekyll and Hyde of cytokines: IL-25 both promotes and limits inflammatory diseases

...ctions and causing asthma. Importantly, IL-25 can simultaneously limit destructive inflammation caused by inflammatory T helper cells commonly found in diseases like inflammatory bowel disease, arthritis and MS." IL-25 can be considered a "good" cytokine by limiting chronic inflammatory responses. At the same ti...

Researchers identify genes in fruitflies that may shed light on human cancer spread

... required for a certain type of cell migration and simultaneously captured a global view of all the genes turned on when cells are on the move. The study, to be published April 3 in Developmental Cell, has implications for understanding cell migration and perhaps controlling cancer cells that move similarly to sp...

Researchers find molecular 'brake' to cell death

...e of CC increases, another mechanism kicks in that simultaneously begins to reduce the size of the nucleotide pool to allow CC to bind to Apaf-1, Tang says. The researchers say this kind of strategy makes sense for the cell, because it acts like a biological fail-safe system to protect against the errant release o...

Scientist-astronaut sends T-cells into space

...pace Agency astronaut-scientist Thomas Reiter will simultaneously activate T-cells in the weightless compartment and in the centrifuge for four hours. "By activating the cells, he'll be simulating the activation that normally occurs in response to infection," Hughes-Fulford explains. "He'll be setting up the whole ...

Ancient global warming drove early primates' dispersal

...first true members of the group appeared virtually simultaneously on Asia, Europe and North America some 55 million years ago. But new research using the latest evidence suggests a completely different migration path from those previously proposed and indicates that sudden, rapid global warming drove the dispers...

Many cleaners, air fresheners may pose health risks when used indoors

...e both air fresheners and ozone-generating devices simultaneously in a room. This could lead to exposures to formaldehyde that are 25 percent higher than California's guideline value. Because other sources of formaldehyde could also be present in the room, exposure to formaldehyde would probably be even higher, the...

New lab technique churns out fungus' potential cancer fighter

...ba University in Japan and the University of Tokyo simultaneously discovered a compound in certain fungi that selectively destroyed cells depending upon a gene called ras--one of the first known cancer-causing genes. They had found rasfonin, a compound that seemed tailor-made to knock out ras-dependent cancers like...

Chewing up a key regulator of fat synthesis keeps mice lean despite a high-fat diet

...C. When we fast, the body starts to burn fat while simultaneously shutting down ACC through a chemical modification called phosphorylation. The Salk researchers found that a critical protein called TRB3 orchestrates a second chemical modification of ACC, known as ubiquitination, which gets rid of the enzyme altoge...

How plants avoid feeling the burn

...r in the charged state (the oxidized state), while simultaneously measuring the electron transport through a single molecule. "The importance of this result is not only for understanding natural systems and photosynthesis, but also for the fact that technically, for the first time, we could hold a molecule in a...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

... drugs by being able to run several types of tests simultaneously on an extremely small scale. The next step in developing this technology is under way in Hayes' laboratory and through the team's collaboration with Joseph Wang, a professor in the Fulton School's Department of Chemical Engineering. Wang's resear...

Molecular DNA switch found to be the same for all life

...at the right time, and in the right manner, while simultaneously avoiding over-replication." The Drosophila results were reported in a paper entitled: Nucleotide-dependent conformational changes in theDnaA-like core of the origin recognition complex. This study was led by Botchan and Nogales, and included Megan...

Encoded metallic nanowires reveal bioweapons

...tection systems that can detect multiple pathogens simultaneously would be ideal for this task. American researchers from Lawrence Livermore National Laboratory led by Jeffrey Tok, in collaboration with groups at Stanford University, University of California at Davis, and Oxonica Inc (formerly Nanoplex Technologie...

Wild vs. lab rodent comparison supports hygiene hypothesis

...suggests that an overly hygienic environment could simultaneously increase the tendency to have allergic reactions and the tendency to acquire autoimmune disease, despite the fact that these two reactions represent two different types of immune responses. The researchers added that their experimental model, which ...

Surprise finding for stretched DNA

...as been shown that they can achieve their goals by simultaneously stretching and overwinding a DNA molecule, or by compressing and underwinding it. "We believe that our work sheds new light on an old and important problem," said Bustamante, "and that, in addition to improving our understanding of DNA/protein inte...

Activation of microRNA inhibits cancer gene in human cancer cells

...ls were treated with chromatin-remodeling drugs to simultaneously inhibit DNA methylation and histone deacetylation. A subset of miRNAs was upregulated in the cancer cells but not the normal cells. Importantly, miR-127, which is downregulated in 75% of the human cancer cells tested, was highly induced after treatme...

Massive duplication of genes may solve Darwin's 'abominable mystery' about flowering plants

...cting genetic novelty by single-gene duplications, simultaneously having a full genome's worth of raw material to elaborate new genetic function could drive sudden evolution. But because of the rapid, massive gene loss after a whole-genome duplication, these events are notoriously difficult to detect after million...

Drug dials down the energy within cells, UM researchers find

...wn to a level that maintains normal function while simultaneously allowing for initiation of a process that selectively kills or disables disease-causing cells." Glick and collaborators published their findings in the June 16 issue of ACS Chemical Biology. The drug, discovered by Glick and coworkers and called be...
