Targeted memory erasure is no longer limited to the realm of science fiction. A new study describes a method through which a selected set of memories can be rapidly and specifically erased from the mouse brain in a controlled and inducible manner. New and old memories have been selectively and safely removed from mice by [...]

Blocking the signals from a protein that activates cells in the immune system could help kill cells that cause a rare form of blood cancer, according to physicists and oncologists who combined computer modeling and molecular biology in their discovery.

Vanderbilt biologist Ken Catania has discovered the secret of “worm grunting” — the Florida practice of driving a wooden stake into the ground and rubbing it with a long piece of steel to produce a grunting sounds that drives nearby earthworms to the surface where they can be collected for bait. The worm grunters are [...]
Scientists were dubious in the early 1980s when they stumbled on small sugar molecules lurking in the centers of cells; not only were they not supposed to be there, but they certainly weren’t supposed to be repeatedly attaching to and detaching from proteins, effectively switching them on and off.

Climate change will have different effects on lakes in warmer and colder regions of the globe. This is the conclusion reached by Japanese and German researchers following studies of very deep caldera lakes in Japan.
A new study reveals how the brain can connect discrete but overlapping experiences to provide a rich integrated history that extends far beyond individually experienced events and may help to direct future choices.

An international team of scientists has discovered microscopic, magnetic fossils resembling spears and spindles, unlike anything previously seen, among sediment layers deposited during an ancient global-warming event along the Atlantic coastal plain of the United States.
A multi-institution team reports results of the largest effort to date to chart the genetic changes involved in the most common form of lung cancer, lung adenocarcinoma. The findings should help pave the way for more individualized approaches for detecting and treating the nation’s leading cause of cancer deaths.

Engineering researchers have just developed a neural probe that demonstrates significantly greater electrical charge storage capacity than all other neural prosthetic devices to date. More charge storage capacity means the device can stimulate nerves and tissues with less damage and sense neural signals with better sensitivity.

Researchers have shown that self-induced breaks in the DNA of immune cells known as lymphocytes activate genes that cause the cells to travel from where they’re made to where they help the body fight invaders. The new finding is the first to link such serious DNA damage to activation of genes not directly involved in [...]
