Islands in the Genome Promote Speciation

...also started identifying “speciation genes,?should tell us if similar genes are employed repeatedly in different genera during the formation of new species. ...

PET imaging reveals the immune system at work

...to see. If you test blood, for example, it may not tell you what's going on in the liver or the spleen. With this technique, the sensitivity for monitoring the immune system is incredible because you're seeing the whole body." That global perspective makes it possible to see critical ancillary responses ...

Adult stem cells aid recovery in animal model of cerebral palsy

Jefferson biologist coaxing human embryonic stem cells to make dopamine with simpler, faster method

Many needles, many haystacks

...oes. Linear motifs are so small that it is hard to tell what features allow them to bind to other molecules. Now Victor Neduva, a PhD student in Russell's group, has developed a method to scan molecules and tease out new linear motifs. "If two or more different proteins share a binding partner, there is ...

Scientist uses form to explain function of key building blocks of life

...ction. In this case, given an NMR pattern, we can tell you how the protein will act. In general, this method may provide information about even more complex biological systems. This is an approach that will be important for larger proteins." Markley notes that an undergraduate and graduate student pla...

Bats use touch receptors on wings to fly, catch prey, study finds

...ir and recorded how the bats caught them. He could tell from the flour imprints on the wings that the bats caught their prey almost exclusively in the stretch-sensitive sweet spots. ...

Mapping alcohol brain damage

...searching proteins was the next step as that would tell them why some cells have impaired function. He has also teamed up with United Kingdom colleagues to find out why people get addicted to alcohol -- with the long-term goal of producing a drug that could reduce alcohol dependence. ...

Technique offers new view of dynamic biological landscape

... gene that's involved in secretion, but it doesn't tell you about the many other processes it could be involved in. With the E-MAP approach, however, the researchers start with the gene and ask about all the processes that it affects. "It gives you a less hypothesis-biased, more objective way of looking...

Alleged 40,000-year-old human footprints in Mexico much, much older than thought

... touching," Feinberg said. "The paleomagnetic data tell us that these things did not move around at all since they were deposited. They haven't been eroded and redeposited anywhere else. They fell while they were still hot, which raises the question of the validity of the footprints. If they were hot, why...

Engineers discover why toucan beaks are models of lightweight strength

...ollow areas," said Meyers. "This is why I jokingly tell my students that toucans have a deep knowledge of mechanics. They don't bother adding structural support in a part of the beak that doesn't really need it." ...

You will remember this

... A team at UCL (University College London) can now tell how well memory will serve us before we have seen what we will remember. Scans of brain activity, published online in the journal Nature Neuroscience, indicate that the brain can actually get into the 'right frame of mind' to store new information ...

Microbiology text tells stories, offers online resources

...dhardt of the University of Michigan. "We like to tell stories about the way microbes are put together, what they must do to grow and survive and how they interact with all other living things." Microbe is paradigm-driven rather than fact-driven. Key concepts are illustrated by inspiring examples that ...

Scientists discover interplay between genes and viruses in tiny ocean plankton

... light, temperature and nutrients. "These results tell us that even the smallest organisms show genetic variation related to the environment in which they exist," said Philip Taylor, director of the National Science Foundation (NSF)'s biological oceanography program, which funded the research. In additi...

Marine mammals are on the frontline of failing ocean health

...a at Davis. "By paying attention to them, it will tell us about our own health and the links between our health and that of the environment." Cats and Otters: A Deadly Link to Land? When Pat Conrad first started studying the death of otters on the California coast, she had no idea that her investigati...

DNA conclusive yet still controversial, Carnegie Mellon professor says

...mall numbers. We would do them a service to simply tell them it matches or it doesn't match," Roeder said. Roeder began her career as a biologist, and much of her current research is focused on using statistical tools to understand the workings of the human genome and the nature of inherited diseases. Sh...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

...e. "We're using these animals as ocean sensors to tell us about oceanographic conditions, and we're also learning how they use the ocean--where they go and what they do," said Daniel Costa, professor of ecology and evolutionary biology at the University of California, Santa Cruz. Costa, along with Barb...

MIT: Oceans are a major gene swap-meet for plankton

...t how do they do it? "We decided to let the cells tell us what is most important to them" by doing a systematic survey of relative abundances among six different types, or clades, of Prochlorococcus across vast environmental gradients in the oceans, Chisholm said. "We found first that two clades are orde...

The closest look ever at the cell's machines

...st of all the machines, and it goes beyond that to tell us how they populate the cell and partition tasks among themselves." The study combined a method of extracting complete protein complexes from cells (tandem affinity purification, developed in 2001 by Bertrand Séraphin at EMBL), mass spectrometry an...

Study finds drug may cut down involuntary movements

...ied by scientists, and now a simple blood test can tell people whether they will develop the disease or not. But since there is no way known to prevent the disease or slow its progression, and for other reasons as well, many patients decline the test, instead waiting to see if they develop symptoms like t...
