When Irfan Rahman talked to young vapers, some complained of bleeding mouths and throats. And these bloody sores seemed slow to heal. Such reports concerned this toxicologist at the University of Rochester in New York. So he decided to investigate what the vapors inhaled from electronic cigarettes might be doing […]

It’s easy to think that the globe’s vast oceans would be effective barriers to the movement of land animals. An elephant can’t swim across the Pacific, after all. But it turns out that plenty of plants and animals — and even people — have unintentionally floated across oceans from one […]

To become Australians, these spiders crossed an ocean

Colleges typically offer two early admissions options – early action, in which students receive a non-binding offer of admission, and early decision, in which students, if accepted, must attend the college in question. While one can argue that there are few drawbacks to early action, early decision (or ED, for short) is […]

What every college-bound student should consider:

A Neandertal child whose partial skeleton dates to around 49,000 years ago grew at the same pace as children do today, with a couple of exceptions. Growth of the child’s spine and brain lagged, a new study finds. It’s unclear, though, whether developmental slowing in those parts of the body […]

Swedish inventor Torbjørn Ludvigsen has spent the last three years developing a new kind of large-format 3D printer that can build furniture-sized objects in any room — surprisingly easily and relatively cheaply. Ludvigsen’s invention, the Hangprinter, employs a system of wires and computer-controlled pulleys anchored to the walls, floor, and […]

Scientists have discovered a small octopus city – dubbed Octlantis – a find that suggests members of the gloomy octopus species (Octopus tetricus) are perhaps not the isolated and solitary creatures we thought they were. Octlantis features dens made out of piles of sand and shells, and is home to up […]

Irish beach washed away 33 years ago reappears overnight

A team of researchers from the University of Houston has reported a breakthrough in stretchable electronics that can serve as an artificial skin, allowing a robotic hand to sense the difference between hot and cold, while also offering advantages for a wide range of biomedical devices.

Artificial ‘skin’ gives robotic hand a sense of touch

The $4bn (£3bn) mission is ending 13 years of discoveries at the ringed planet by ditching itself in the atmosphere. With an expected entry speed of 120,000km/h (76,000mph), the spacecraft will rapidly be torn to pieces. Scientists, however, hope to gain new information on the chemical composition of Saturn’s gases […]
