However, two rival teams, one in France and one in Switzerland, are now striving relentlessly towards the same goal: to create the fastest sailboat ever built.

One is headed by the former world title holder, and there are two brothers involved — but on opposing teams.

Paul Larsen is a sailing speed freak. His Vestas Sailrocket 2 boat broke the world speed sailing record for a mile in 2012: 78.26 mph! What’s he up to now?

Caltech physicist Sean Carroll explains dimensions in ways that even a 5-year-old can understand.

The 2018 eruption of Kīlauea Volcano in Hawai’i provided scientists with an unprecedented opportunity to identify new factors that could help forecast the hazard potential of future eruptions.

The properties of the magma inside a volcano affect how an eruption will play out. In particular, the viscosity of this molten rock is a major factor in influencing how hazardous an eruption could be for nearby communities.

Very viscous magmas are linked with more powerful explosions because they can block gas from escaping through vents, allowing pressure to build up inside the volcano’s plumbing system. On the other hand, extrusion of more viscous magma results in slower-moving lava flows.

PHP site’s user database was hacked in recent source code backdooring attack.

The two cases of P.1 found in Boulder County are the first of this variant detected in the state, according to the state health department.

For some of us—isolates, happy in the dark—code is therapy, an escape and a path to hope in a troubled world.

Why did “A Brief History of Time” make its author the most famous scientist in the world?

A research team led by Professor Pan Jianwei and Professor Xu Feihu from University of Science and Technology of China achieved single-photon 3D imaging over 200 km using high-efficiency optical devices and a new noise-suppression technique, which was commented on by the reviewer as an almost “heroic” attempt at single photon lidar imaging at very long distances.

Lidar imaging technology has enabled high precision 3D imaging of target scenes in recent years. Single photon imaging lidar is an ideal technology for remote optical imaging with single-photon level sensitivity and picosecond resolution, yet its imaging range is strictly limited by the quadratically decreasing count of photons that echo back.

Researchers first optimized transceiver optics. The lidar system setup adopted a coaxial scanning design for the transmit and receive optical paths, which can align the transmitting and receiving spots more precisely and achieve higher-resolution imaging in comparison with traditional methods.
