Science's Breakthrough of the Year: Watching evolution in action

... claim top honors as the Breakthrough of the Year, named by Science and its publisher AAAS, the nonprofit science society. In 2005, scientists piled up new insights about evolution at the genetic level and the birth of species, including information that could help us lead healthier lives in the future....

Penn Surgeons Use Completely Robotic Surgery to Successfully Treat Prostate Cancer

...pert in robotic surgery, was recruited to Penn and named Chief of the Division of Urology at Penn Presbyterian Medical Center, where the robotic prostate program is based. There are many factors that make robotics an exceptionally valuable tool in the operating room during p...

Scientists learn to predict protein-stabilizing ability of small molecules

...pert in robotic surgery, was recruited to Penn and named Chief of the Division of Urology at Penn Presbyterian Medical Center, where the robotic prostate program is based. There are many factors that make robotics an exceptionally valuable tool in the operating room during p...

Wild Gorillas Handy with a Stick

...ge, Breuer et al. observed an adult female gorilla named Leah (a member of a long-studied gorilla group) at...#62; In a separate incident, a second adult female named Efi (who belonged to a different group) emerged from the forest and broke off the thin, long trunk f...

Novel enzyme offers new look at gene regulation

...was the identification of a novel protein, JHDM1A, named for JmjC histone demethylase 1A. A similar protein exists in baker's yeast and has the potential to remove trimethyl groups. JmjC is only a section of the entire JHDM1A protein, but is required for its demethylase activity. The authors showed that d...

From one cell, many possible cures

...er for Gene Therapy's Web site, "stem cells are so named because they are like the stems on a tree that can produce new leaves and flowers each year." Each stem cell has the ability to divide so as to produce a perfect copy of itself; the copy then can become a "workhorse" cell, such as a bone or nerve cel...

UK sperm donor crisis

... for donors up to the age of 40." Dr Stewart said named donations had been practised in several countries for some years and the UK is having to learn how to make the transition from anonymity. It would help recruitment, she believed, if uncertainties about the eventual release of identifiable information...

Marsupial genome reveals insights into mammalian evolution

...ut are scattered over various chromosomes. We have named this complex 'The Immune Supercomplex.'" Belov et al. found that while the size and complexity of the opossum MHC is closer to eutherian (placental) mammals, its organization is closer to fish and birds. "The clues we unearthed by looking at differ...

Breakthrough for stem cell research

...rd injury and even breast cancer. "The new line, named 'Endeavour 1', is only the fifth human embryonic stem cell line to be produced in Australia," said UNSW Professor Bernie Tuch, Director of the DTU. "We now hope to collaborate with other researchers, using this line. We will also make it available t...

Pitt professor's theory of evolution gets boost from cell research

...ssor of the history and philosophy of science, was named a fellow in Pitt's Center for the Philosophy of Science and a fellow of the prestigious World Academy of Arts and Science. ...

Gene needed for butterfly transformation also key for insects like grasshoppers

...f Washington research shows that a regulatory gene named broad, known to be necessary for development of insects that undergo complete metamorphosis, also is key for the maturation of insects that have incomplete metamorphosis. The work appears to present the first molecular evidence that the nymphal stage...

Discovery of new molecular tools for biosynthesis could lead to advances in use of pectin

...oding a pectin biosynthetic enzyme, which the team named galacturonosyltransferase-1 or GAUT1. The researchers discovered the gene and the protein it encodes while searching the genetic map database for a common laboratory plant in the mustard family, Arabidopsis thaliana. The identification of GAUT1 as ...

Cholesterol gets 'thumbs up' for role in digit development

...Biology. The developmental protein at work here, named Sonic hedgehog after the video game character, was discovered in the early 1990s and shown to have important roles in patterning the developing embryo, including proper digit patterning. Chiang led the early studies showing that mice without Sonic ...

Newly discovered protein kills anthrax bacteria by exploding their cell walls

...ey have identified a second lysin, which they have named PlyPH, with special properties that make it not only a good therapeutic agent, but also useful for large-scale decontamination of areas like buildings and military equipment. The new protein has several advantages. Most lysins, including PlyG, are o...

Hantavirus found in African wood mouse

... in 1976, the first hantavirus was found near--and named for--the Hantaan River near Seoul, South Korea. "We don't yet know what symptoms the Sangassou virus might cause or how virulent it is," said ter Meulen, "but we have already obtained preliminary evidence that the Sangassou virus can infect humans,...

Neuroscientists discover new cell type that may help brain maintain memories of smells

...rns of synaptic connections made by the other five named but as yet unstudied brain cells in the olfactory bulb. ...

Common enzyme is a key player in DNA repair

...maging agents, the so-called SOS response. Kenyon named the damaged-inducible (Din) genes in order of discovery, and DinB was the second one she found. "Knocking it out didn't seem to have an obvious effect ," Walker said. "We couldn't find anything interesting in the mutant bacteria." Since then, the kn...

Protein finding could lead to treatment for inflammatory diseases

...el to inhibit inflammatory responses. MC160 is so named because it was the 160th gene of the molluscum contagiosum virus (MCV) sequence. "This is a really important protein for a couple of reasons," said Joanna L. Shisler, a professor of microbiology in the U. of I. College of Medicine at Urbana-Champaign...

Polymer aids in blood clotting, pointing way to new treatment

... pump-like enzyme that allows proton transport. He named it the acidocalcisome for its acidic and calcium components. Docampo has since found virtually identical pyrophosphate-containing pouches in numerous prokaryotic organisms, challenging the theory on the origin of eukaryotic organelles and suggesting...

Georgia Tech accelerates drug discovery with new IBM supercomputing cluster

...the solution is IBM Rear Door Heat eXchanger (code named "Cool Blue,") a technology component that can use the existing chilled water supply for air conditioning systems already located in the majority of customer datacenters to reduce server heat emissions into the room by up to 55 percent. Georgia Tech h...
