How T lymphocytes attack

...our destroyed by T lymphocytes? This scenario has recently been visualised by researchers at the Institut Curie. The original images obtained and assembled in twelve video sequences are the result of close collaboration between a specialist in two-photon microscopy, Luc Fetler, an INSERM scientist in the CN...

Satellites shed light on global warming

... According to Cipollini, these waves have been recently observed to alter the colour of the sea, therefore they are believed to have some effect on phytoplankton ?the tiny chlorophyll-pigmented algal cells that populate the oceans in huge numbers and play a leading role in the global carbon cycle and the ...

Cancer scientists create 'human' leukemia process to map how disease begins, progresses

'Hidden-hero' microbes in soil, water may help naturally clean toxic sites

...m groundwater," he said. "In fact, my FSU group recently isolated a new 'wonderbug,' a metal-reducing bacteria we named Geobacter FRC-32," Kostka added. "The genome of this organism now has been sequenced, and we will use that genome sequence and those of other 'bugs' at Oak Ridge in developing our new bio...

Ring-around-the-cell

...search at the Weizmann Institute of Science, which recently appeared in the online journal PLoS ONE, has revealed in unprecedented detail how the roving cells whose job is to digest bone seal off their work area as they get down to business. The cells, called osteoclasts, have some unique features not seen i...

Scientists reveal structure of gateways to gene control

...iscoveries about gene regulation, made possible by recently developed laboratory equipment for high-volume, or massively parallel, DNA sequencing. "Traditional DNA sequencing methods processed one DNA strand at a time, but now we can sequence hundreds of thousands of DNA strands at once, rapidly learning inc...

Cholera pathogen reveals how bacteria generate energy to live

...about how bacteria generate energy to live. In two recently published papers, the scientists add key specifics to the molecular mechanism behind the pathogen that causes cholera. The work could provide a better understanding of this pathogen, while also offering insight into how cells transform energy from th...

Breathing easy: When it comes to oxygen, a bug's life is full of it

...rotron x-rays, an advanced form of x-ray scan, has recently allowed scientists to learn much more about how insects breathe. The new imaging technology allows scientists to observe the respiration of live bugs. This advance in technology also comes at a time when physiologists are learning more about the g...

A sweet step toward new cancer therapies

...rry the necessary positive charges. In a series of recently published papers, they first showed that their method can be used to selectively cleave different bonds and then demonstrated that it can be used to identify sulfate-laden proteins and to pinpoint the location of the sulfate groups on them. In the...

By 2048 all current fish, seafood species projected to collapse

...appearing from ocean ecosystems and this trend has recently been accelerating," said lead author Boris Worm. "Now we begin to see some of the consequences. For example, if the long-term trend continues, all fish and seafood species are projected to collapse within my lifetime -- by 2048." Worm is an assistant...

Early-stage immune system control of HIV may depend on inherited factors

...s analyzed blood samples from more than 100 people recently infected with HIV, first determining their specific HLA types by DNA analysis. Then they focused on 173 HIV protein fragments known to bind to those HLA types to see if particular peptides were more powerful in activating the HIV-specific CD8 respon...

With fruit fly sex, researchers find mind-body connection

...ical roots of human behavior. For example, McKeown recently helped discover a genetic mutation that causes flies to develop symptoms similar to Alzheimer's disease ?a gene very similar to one found in humans. Some of McKeown's recent work focuses on understanding gene networks that control sexual behavior....

Male contraception: One door opens, another closes

... But change may be in the air. Lissner cites the recently opened Intra Vas Device trial as proof. The long-term male contraceptive is being developed by a startup company, supported by a small U.S. National Institutes of Health grant. Due to popular demand, the trial has been expanded to four U.S. cities an...
