Dangerous pathogens use this sophisticated machinery to infect hosts
A detailed new model of a bacterial secretion system provides directions for developing precisely targeted antibiotics.
Death of the middleman? Imagining a cheaper, fairer marketplace for digital goods
Researchers see a blockchain-driven future where cars, homes and appliances can buy and sell digital information.
Ultra-clean fabrication platform produces nearly ideal 2D transistors
Columbia Engineering researchers report that they have demonstrated a nearly ideal transistor made from a 2D material stack — with only a two-atom-thick semiconducting layer — by developing a comple..
Scientists capture first-ever video of body’s safety test for T-cells
For the first time, immunologists have captured on video what happens when T-cells undergo a type of assassin-training program before they get unleashed in the body. A new imaging technique that allow..
Metals influence C-peptide hormone related to insulin
Metals such as zinc, copper and chromium bind to and influence a peptide involved in insulin production, according to new work. The research is part of a new field of 'metalloendocrinology' ..
Cell polarity: An aurora over the pole
Recent research has identified the master switch that triggers the symmetry breaking process in the zygotes of the nematode worm, Caenorhabditis elegans.
Researchers unravel mechanisms that control cell size
A multidisciplinary team has provided new insight into underlying mechanisms controlling the precise size of cells. The researchers found that 'the adder,' a function that guides cells to gr..
Earliest evidence of the cooking and eating of starch
New discoveries made at the Klasies River Cave in South Africa's southern Cape, where charred food remains from hearths were found, provide the first archaeological evidence that anatomically mod..
Early dengue virus infection could ‘defuse’ zika virus
The Zika virus outbreak in Latin America has affected over 60 million people up to now. The infection can have potentially fatal consequences for pregnant women and their unborn children: many childre..
Heart of next-generation chip-scale atomic clock
Physicists have demonstrated an experimental, next-generation atomic clock — ticking at high 'optical' frequencies — that is much smaller than usual, made of just three small chips plus su..
