Hopkins researchers discover genetic switch that turns off an oxygen-poor cell's combustion engine

...e met by two major types of sugar ( glucose) using machines similar to the two types of engines in a hybrid car. One machine, the mitochondrion, is an organelle that breaks down the glucose-using oxygen and produces ATP. The other does the same thing - albeit less efficiently - without using oxygen in a pro...

The closest look ever at the cell's machines

... entire protein household of yeast, turning up 257 machines that had never been observed. It also revealed new..., cells continually dismantle and reassemble their machines at different stages of the cell cycle and in response to environmental challenges, such as infection...

Young scientists turn to gel to ease side-effects of cancer treatment

...treat the tumour, enabling them to calibrate their machines accordingly. Andrew Wilson said: "This technique should allow more rapid, accurate, and therefore safer treatment of malignant tumours." A different formula of the gel can be used as a phantom in the detection of brain tumours. Working with resear...

Many needles, many haystacks

Most of what happens in cells is the work of machines that contain dozens of molecules, chiefly proteins...he chemical 'spelling' of a protein and guess what machines it fits into, we'd know a lot more about what happens in cells," says Rob Russell, head of the Heide...

The shape of things to come: Morphology database going global

...ound the world. Distributing the images on several machines ensures there are backup copies and can reduce both the amount of disk space on each machine and the cost to any one institution. Although scientists will be the only ones to have access to the system to deposit, retrieve or comment on items, the sy...

Student scientists create living bacterial photographs

...t, so the students had to engineer the unicellular machines to work as a photo-capturing surface. UCSF biophysics graduate student Anselm Levskaya and his adviser, Dr. Chris Voigt, first engineered the bacteria to sense light by adding a light receptor protein from a photosynthetic blue-green algae to the E...

Study provides insight into cellular defenses against genetic mutation

...A to mature, it must be cut and pasted by cellular machines that re-assemble end to end only exons in the final template for protein construction. In recent years, Maquat's team has confirmed that complexes that identify early nonsense codons form at exon-exon junctions the places where each "must read" secti...

NYU biologists map out early stages of embryo formation

...ation among a relatively small number of molecular machines required for proper early embryonic development in C. elegans," said Fabio Piano, an assistant professor in NYU's Department of Biology, who headed the research team. "This may also be the case for human embryogenesis. The diagrams linking all these ...

MERIS monitoring tracks planetary photosynthesis levels

... pool of computers can do faster and better. These machines do not have to be in the same building, country or even continent ?they simply have to be linked together. A Grid provides its user with massive amounts of memory and processing power in order to tackle very complex tasks. ESRIN has taken up Grid c...

Frog peptides block HIV in lab study

Building a protein name dictionary from full text: a machine learning term extraction approach

...uency terms in an article, and uses support vector machines (SVM) to identify biological entity names. It is also computationally efficient and robust to noise commonly found in full text material. We use the method to create a protein name dictionary from a set of 80,528 full text articles. Only 8.3% of the ...
