Comment Video shows the thruster control lag ? (Score 1) 113 113

It looks like the video shows the lag of the rocket thrusts reaction. First the thrust is vectored right and it stays right even after the tipping point. And after being several seconds late it vectors to left, causing the excess force.

Submission + - Scientists Create A Tractor Beam On Water->

GlowingCat writes: Physicists at The Australian National University (ANU) have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach. The team, led by Dr Horst Punzmann, discovered they can control water flow patterns with simple wave generators, enabling them to move floating objects at will.

Submission + - Toward a Quantum Theory of Gravity?->

GlowingCat writes: One of the main problems in attempting to calculate gravitational interactions with gravitons has been that the calculations produced unphysical infinities at almost every step. Bern and colleagues, however, managed to enormously simplify the calculations by showing that, at least in some cases, gravitons can be replaced by two copies of gluons — the carriers of the strong nuclear force. If this double-copy-of-gluons relationship holds in general, this clue could potentially lead to a dramatic breakthrough in the search for a quantum theory of gravity.

Submission + - Extending human vision range into near-infrared with Vitamin A

asvravi writes: A crowd-funded experiment on seeks to extend the color range of human vision into near infra-red by only manipulating the amounts of vitamin A1 and A2 in the diet of subjects.
It has now reported initial success with human eye response at 950nm as compared to 850nm before the diet modifications.
How long until full night vision?
