Nearly all species have some ability to detect light. At least three types of cells in the retina allow us to see images or distinguish between night and day. Now, researchers have discovered in fish yet another type of cell that can sense light and contribute to vision.

Two new studies reveal a way to increase the body’s appetite for gobbling up the cancer stem cells responsible for acute myeloid leukemia (AML), a form of cancer with a particularly poor survival rate. The key is targeting a protein on the surface of those cells that sends a “don’t eat me” signal to the [...]

A drug similar to one used in clinical trials for treatment of rheumatoid arthritis and psoriasis has been found to rescue memory in mice exhibiting Alzheimer’s symptoms.

New research shows that training your brain may be just as effective as training your muscles in preventing anterior cruciate ligament knee injuries, and suggests a shift from performance-based to prevention-based athletic training programs.

Dye-sensitized solar cells are expected to power Air Force unmanned aerial vehicles in the future because they are an optimum energy harvesting source that may lead to longer flight times without refueling.

Scientist have created a mechanism to measure happiness of millions of bloggers. Their “hedonometer” gathers sentences beginning “I feel…” Then, applying standardized “psychological valence” of words, each sentence receives a happiness score. Their approach can let them measure happiness levels of, e.g., people over 65 in Oregon on Wednesdays. The happiest day in 4 years: [...]

Oil and gas started out as living organisms that died, were compressed, and were heated under layers of sediments in the Earth’s crust. Scientists have debated for years whether some of these hydrocarbons could have been created deeper in the mantle and formed without organic matter. Now for the first time, scientists have found that [...]
New information about the genes involved in a mammal’s early brain development, including those that contribute to neurological disorders such as autism and mental retardation, has been discovered. The study is the first to use high-throughput sequencing to uncover active genes in developing brains, and it may be the best evidence yet for the activity [...]

Biologists show that in the plant world, bigger isn’t necessarily better. “Until now most of the thinking has suggested that to be a good competitor in the forest, you have to be a big plant,” according to one of the researchers. “But our research shows it’s virtually the other way around.”

A study has identified a way to turn off a key signaling pathway involved in physiological processes that can also stimulate the development of cancer and other diseases. The findings may lead to new treatments and targeted drugs using this approach.
