[ Watch the Video ] A new method for visualizing mechanical forces on the surface of a cell, reported in Nature Methods, provides the first detailed view of those forces, as they occur in real-time. “Now we´re able to measure something that´s never been measured before: The force that one molecule applies to another molecule across the entire surface of a living cell, and as this cell moves and goes about its normal processes,” says Khalid Salaita, assistant...

The carbon footprint of humans will be reduced by four awards for plant and microbial research issued under a new joint U.S./Japanese program Four joint United States and Japanese research teams have been awarded funding totaling about $12 million (about Yen 960 million) to develop new environmentally-friendly techniques to increase the production of renewable biofuel and reduce pesticide use. These environmentally-friendly techniques will be based on studies of metabolites--chemical...

A new technique developed by researchers at RIKEN has clarified the location and dynamics of specific metabolites in a single cell of the alga Chara australis. The findings reveal that these metabolites are regulated and fluctuate under stress conditions, providing insight into previously-unknown functions of the vacuole in cellular processes. Metabolites, the intermediates and products of chemical reactions that sustain all living organisms, play a central role in cellular processes...

Molecules in their breath, sweat and skin have been used to detect humans in a simulation of a collapsed building, raising the prospect of portable sensors for use in real-life situations, such as the devastating aftermath of the 9/11 attacks and more recent disasters in New Zealand and Japan. Published today, Monday 12 September, in IOP Publishing's Journal of Breath Research, the study examined flumes of air to create a preliminary profile of molecules that could indicate human activity...

  Revealing how cells communicate, Tel Aviv University research could lead to new cancer drugs and more Cell communication is essential for the development of any organism. Scientists know that cells have the power to "talk" to one another, sending signals through their membranes in order to "discuss" what kind of cell they will ultimately become – whether a neuron or a hair, bone, or muscle. And because cells continuously multiply, it's easy to imagine a cacophony of...

Significant differences in metabolites between men and women lead researchers to propose gender-specific treatment for some diseases Analyses of the metabolic profile of blood serum have revealed significant differences in metabolites between men and women. In a study to be published on August 11 in the open-access journal PLoS Genetics, scientists at the Helmholtz Zentrum Mnchen have concluded that there is a need for gender-specific therapies. Gender-specific therapies may be required for...

In the wake of last year's creation of the first self-replicating cell with a synthetic genome "“ which was quickly followed by a request from President Barack Obama for a report by the Presidential Commission for the Study of Bioethical Issues "“ a series of essays in the Hastings Center Report examines the social challenges that synthetic biology presents. Among the authors is the chair of the Presidential Commission for the Study of Bioethical Issues, who discusses its report...
