A new fossil primate from Myanmar (previously known as Burma) suggests that the common ancestor of humans, monkeys and apes evolved from primates in Asia, not Africa as many researchers believe.
One-step screening for both genetic and chromosomal abnormalities has come a stage closer as scientists announced that an embryo test they have been developing has successfully screened cells taken from spare embryos that were known to have cystic fibrosis. The technique, known as genomewide karyomapping, was capable of not only detecting diseases caused by a [...]

Physicists and astronomers have developed a new synthesis method, which has led them to the discovery of fluorescent silicon nanoparticles, and may ultimately help track the uptake of drugs by the body’s cells.

Scientists are focusing on a new concept in fighting airborne pathogens by manipulating what is called the “switching time,” the point at which a highly regulated immune response gives way to powerful cells that specialize in fighting a specific invading bug. In the case of tuberculosis, researchers are using mathematical modeling to determine whether a [...]

Researchers have developed a successful way to grow molecular wire brushes that conduct electrical charges, a first step in developing biological fuel cells that could power pacemakers, cochlear implants and prosthetic limbs.

Researchers have found that synaptic plasticity, long implicated as a device for “change” in the brain, may also be essential for stability.

Millions of would-be galaxies failed to develop after being exposed to intense heat from the first stars and black holes formed in the early Universe, according to new research. Our Milky Way galaxy only survived because it was already immersed in a large clump of dark matter which trapped gases inside it, scientists have found.

Researchers have determined that the effects of 6 percent hydrogen peroxide, the common ingredient in professional and over-the-counter whitening products, are insignificant compared to acidic fruit juices. Orange juice markedly decreased hardness and increased roughness of tooth enamel.

Scientists have found that a portion of the brain that handles decision-making also helps decipher different sounds.

Like a mechanic popping the hood of a car to get at a faulty engine, a tumor-suppressing protein allows cellular repair mechanisms to pounce on damaged DNA by overcoming a barrier to DNA access.
