The researchers used saliva samples contributed by 34 pairs of identical male twins between the ages of 21 and 55. They scoured the men’s genomes and identified 88 sites on the DNA that strongly correlated methylation to age. They replicated their findings in a general… read more

University of Manchester researchers have successfully carried out the first rewire of genetic switches, creating what could be a vital tool for the development of new drugs and even future gene therapies.
They rewired the genetic switches of bacteria so they are activated by a synthetic molecule instead of naturally occurring molecules found in cells.
Ignition — the process of releasing fusion energy equal to or greater than the amount of energy used to confine the fuel — has long been considered the “holy grail” of inertial confinement… read more

Researchers at Washington University School of Medicine and Florida Atlantic University have used the “Granger causality” technique, originally developed to use current economic data to forecast changes in the economy, to determine the flow of information from one part of the brain to another.
The economic technique involves comparisons of streams of data known as time series, such as fluctuations in the stock market index.
It will provide… read more
By using light, researchers at UC Santa Barbara have manipulated the quantum state of a single atomic-sized defect in diamond — the nitrogen-vacancy center — in a method that allows for more unified control than conventional processes.
The method is also more versatile, and opens up the possibility of exploring new solid-state quantum systems.
“In contrast to conventional electronics, we developed an all-optical scheme… read more

An autophagy inhibitor has counteracted nanoparticle-induced lung damage in mice from ployamidoamine dendrimers (cause lung damage by triggering programmed autophagic cell death), Chinese Academy of Medical Sciences researchers have found.
The findings suggest that compounds could be developed that could be incorporated into the nano product to protect against lung damage, or patients could be given pills to counteract the effects. The findings could also provide important insights into… read more
Newcastle University and University of Calgary scientists expect to begin trials ih May to find out if microbes can unlock the vast amount of energy trapped in the world’s unrecoverable heavy oil deposits.
An estimated six trillion barrels of oil remain underground because the oil has become either solid or too thick to be brought to the surface at economic cost by conventional means.
The scientists’ research has… read more

Two teams of British researchers are seeking permission to create “cybrid” embryos that would be around 99.9 per cent human and 0.1 per cent animal to produce embryonic stem cells.
They want to use the stem cells to understand and provide new treatments for diseases such as Alzheimer’s, Parkinson’s, cystic fibrosis, motor neuron disease and Huntington’s.
Scientists from Columbia University, IBM and the University of New Orleans today announced a new, three-dimensional designer material assembled from two different types of nanoparticles.
In the June 26 issue of the journal Nature, the team describes the precision chemistry methods developed to tune the particles’ sizes in increments of less than one nanometer and to tailor the experimental conditions so the particles would assemble themselves into repeating 3-D… read more

The International Institute for Species Exploration at Arizona State University and an international committee of taxonomists has just announced the top 10 new species described in 2007.
On the list are an ornate sleeper ray, with a name that sucks: Electrolux; a 75-million-year-old giant duck-billed dinosaur; a shocking pink millipede; a rare, off-the-shelf frog; one of the most venomous snakes in the world; a fruit bat; a mushroom; a… read more
Boron crystalline nanowires (“nanowhiskers”) may replace carbon nanotubes as nanoscale semiconductors.

Two years after the human genome was mapped, scientists are drawing a stunning insight by comparing human genes with those of mice. Researchers now agree human genes are definitely missing something; they’re just not entirely sure what. Figuring it out could involve arguments about the very definition of the word “gene.”

Scientists from Spain’s Universitat Autònoma de Barcelona (UAB), along with colleagues from the Spanish National Research Council, have successfully developed an identification system in which mouse embryos and oocytes (egg cells) are physically tagged with microscopic silicon bar code labels. They expect to try it out on human embryos and oocytes soon.
The purpose of the system is to streamline in vitro fertilization and embryo transfer procedures. If egg… read more

The fight against cancer could be helped by the discovery of a strain of mice which appear to have the ability to resist the disease.
