Stanford researchers establish center for physics-based simulations of biological structures

...logical structures, the fundamental equations that describe these systems have a lot in common. We're going to create a package that can simulate everything from proteins folding to human movement." Mathematical and computational models provide the framework for understanding complexity in life--a requiremen...

Bugs in the gut could play key role in understanding human disease and drug toxicity

...ished today in Nature Biotechnology , researchers describe how microbes in the gut form the second largest metabolic 'organ' in the body and play a key role in disease processes alongside genetic and environmental factors. Microbes in the gut can weigh up to one kilogram in a normal adult human, and collecti...

U-M scientists see ubiquitin-modified proteins in living cells

T cell's memory may offer long-term immunity to leishmaniasis

...ber issue of Nature Medicine, the Penn researchers describe how the discovery can offer immunity to leishmaniasis, even without the persistent presence of the parasite that caused the disease. Their findings encourage a new approach to creating a vaccine against leishmaniasis and other immune cell mediated d...

Study describes basic mechanism in cell growth control involving damaged DNA

...and the UNC Lineberger Comprehensive Cancer Center describe - for the first time - how some proteins interact to ensure that the cell does not continually divide when its DNA is damaged. Although not yet clinically applicable, the study's findings offer new knowledge on how cells rapidly degrade unnecessary a...

Researchers provide road map for generating B cells from stem cells

...ming an antibody-producing B cell. The researchers describe four critical stages on the way from a multi-potent precursor to a committed B-cell and suggest how combinations of regulatory proteins and signaling pathways direct maturing cells through each crossroad, guiding them down one specific developmental ...

Laboratory test of evolutionary theory confirms importance of links between populations

...pulations. Ecologists use the term "gene flow" to describe the spread of genetic variants that accompanies the movements of individuals. This study provides the first direct empirical evidence that gene flow across a heterogeneous landscape can alter the dynamics of coevolution. "By working with microbes th...

Researchers find protein that makes long-term memory possible

...rm memory. "In the Science article, we describe a series of experiments showing that the chemical reaction that generates mBDNF actually takes place in the brain, and that mBDNF is essential to the long-term memory process," said Dr. Pang. To conduct their experiments, the researchers re...

...grey, and black. Whilst it is quite common to describe people or emotions metaphorically in terms of colours, GW actually reported vividly seeing them. Indeed, when "James" (a pink word) was written in the wrong colour (e.g. blue), her reaction times were slowed. Synaesthesia is a condition foun...

$2.8 million NIH grant awarded to UH for bionano training

...basic degrees that delineate disciplines no longer describe real research." Along those lines, what is especially innovative about this grant extends beyond just the recent money awarded. While UH is the lead center and the fellowships are being administered through IMD, Pettitt's role as director of the K...

International human genome sequencing consortium describes finished human genome sequence

...of the journal Nature . In the paper, researchers describe the final product of the Human Genome Project, which was the 13-year effort to read the information encoded in the human chromosomes that reached its culmination in 2003. The Nature publication provides rigorous scientific evidence that the genome se...

New DNA repair enzyme makes mistakes to save lives of cells

...an Molecular Biology Organization, the researchers describe how DNA polymerase Q, or POL-Q, has the exceptional ability to bypass damaged spots in the DNA sequence that are caused by a cell's normal wear and tear or other abuses. In addition, it is the only known enzyme that orchestrates not only one, but two...

Biodiversity: measuring up to the loss

...tional, IUCN and the Institute of Zoology, London, describe a new way to generate such an index that can measure trends in extinction risk for complete classes of organisms, starting with the world's 10,000 bird species. Their "Red List Index" measures changes in overall extinction risk over time for all bird...

New Royal Society journal studies

...y of their deals using mathematical equations that describe how the prices of assets change with time. Sometimes these equations can be very difficult to solve and require long computer calculations for an accurate answer. In this study we look at one of the solution methods and work an approximation for wh...

Extinction in ocean's mud presages key ecological changes

...urnal Science, an international team of scientists describe work in which the ocean mud and the many animals that live there are used to forecast how the extinction of species alters important ecological processes that sustain life at the bottom of the ocean. The team's work was funded by the National Sci...

...anoise Le Deist and colleagues from INSERM, Paris, describe how a complete deficiency in the CD3 epsilon chain of the T cell receptor, which binds foreign antigens and thus targets them for destruction, causes SCID. The authors studied 3 families with, or having had lost, infants with SCID of an unknown ...

Seeking better cancer treatments

...rms of research and knowledge gained, the partners describe the projects as being 110% successful, having led to new patents and published papers. These will lead, in turn, to co operation with other patent holders to produce anti-cancer drugs for clinical trial and the market. According to Manuel Carrondo, C...

Study shows stem cells can preserve vision
