In an industry that celebrates newcomers and disruptors, tech companies over a decade old take on the air of grizzled veterans. Still, some Silicon Valley companies manage to ride out the cycles. Founded in 1939 and stil...

An answer to a quantum-physical question provided by the algorithm Melvin has uncovered a hidden link between quantum experiments and the mathematical field of Graph Theory. Researchers from the Austrian Academy of Scien...

U.S. and European physicists searching for an explanation for high-temperature superconductivity were surprised when their theoretical model pointed to the existence of a never-before-seen material in a different realm o...

New research suggests that a slightly underactive thyroid may affect a women's ability to become pregnant -- even when the gland is functioning at the low end of the normal range.

When the immune system mobilizes its troops, antigen-presenting cells play an important role. They can emerge from white blood cells (monocytes) that circulate in the blood. Scientists have now taken a closer look at the...

When ionizing radiation passes through living tissue, it interacts with molecules present in the cells, stripping away electrons and producing charged species known as ions. The electrons produced by this process, known ...

The ability to map both the magnitude and orientation of forces on a cell provides a powerful tool for investigating not just blood clotting but a range of biomechanical processes, from immune cell activation and embryo ...

There are major measurement issues in patient experience data collected from US emergency departments, including high variability and limited construct validity, according to an analysis.

Researchers have chemically imprinted polymer particles with DNA strands -- a technique that could lead to new materials for applications ranging from biomedicine to the promising field of 'soft robotics.'

Blood vessels are the supply lines of the human body, bringing nutrients and oxygen to cells and carrying away waste. Controlling the growth of these supply lines can be an effective tactic to combat several different ty...

Researchers have identified a cause for chronic bad breath (halitosis), with the help of gene knockout mice.

Natural killer cells are among the most abundant immune cells in the uterus during the first trimester of pregnancy, but their numbers decline substantially after the placenta forms. A new study shows that this cell popu...

Scientists hope that understanding how immune cells adapt as they enter different tissues will spur the design of better, more specific, medicines for Crohn's disease.

When ionizing radiation passes through living tissue, it interacts with molecules present in the cells, stripping away electrons and producing charged species known as ions. Ionizing radiation used for cancer treatment i...

Solar power is giving millions of people access to electricity for the first time - could they bypass traditional fossil fuel grids altogether?

Natural killer cells - which destroy cancer cells and pathogens - also help early fetuses grow, a finding that may lead to treatments to prevent miscarriage

From a woman who sweats blood to a man with a giant stone in his bladder, a number of intriguing medical cases made headlines in 2017.

MANY people fear that the rapid disappearance of Arctic sea ice spells doom for polar bears. The effect of global warming on another famous northern species, the reindeer, is, however, less cut and dried. Until recently,...

IN 1674 George Ravenscroft, an English glass merchant, was granted a patent for the discovery made at his factory in London that adding lead oxide to the melt resulted in a clearer, more durable product. Thus was born le...

MODERN life is so cushy that some wonder if human evolution has stopped. Unlikely, reply biologists, for family sizes (and therefore numbers of descendants) still vary. A study just published in the Proceedings of the Na...

THE machines are coming. A much-cited study in 2013 concluded that half of American jobs were at risk in the coming decades. Writers are not immune. Another paper, which surveyed researchers into artificial intelligence ...

Just don't bother BRIGHT colours in the natural world are often a warning. In the case of tiger snakes, blue-ringed octopuses, arrow-poison frogs, hornets and many other species, the warning is that the animal carries to...
