Biologists
at The Scripps Research Institute have conducted experiments on C.
elegans roundworms and identified a brain hormone that selectively
triggers fat burning in the gut, regardless of food intake and without
any obvious side effects – and the findings could have implications for
humans.

US Army's hoverbike takes flight
What started as crazy DIY project
in an Australian backyard six years ago has now blossomed into a
cutting-edge aircraft for the US Army. We've tracked the various
iterations of the Malloy Hoverbike since inventor Chris Malloy first
showed off a prototype in 2011, and now after teaming up the US Department of Defense
the mechanical engineer has seen a military version of his little baby
take flight, with officials hoping to use it for resupply missions to
create an "Amazon on the battlefield."
The
latest version of the oversized quadcopter might now have a suitably
militarized moniker, joint tactical aerial resupply vehicle (JTARV), but
is still known affectionately as a hoverbike, even in the US Army's
press release.
Like the four-rotor vehicle
we spied up close back in August 2014, the JTARV is an electric,
rectangular-shaped quadcopter with the ability to do some heavy lifting.
In its current form the prototype is
able carry 300 lb (136 kg), though army researchers are hoping to extend
this by way of a hybrid propulsion system which could one day have it
flying along at altitudes of thousands of feet and speeds of 60 mph (96
km/h).
"We're exploring increasing payload
capacity to 800 lb (362 kg) and extending the range up to 125 miles (200
km)," said Tim Vong, associate chief of the US Army Research Laboratory
(ARL). "We're also looking to integrate advanced intelligent navigation
and mission planning. We're looking to end up with a modular, stable
platform that can be used for even more dynamic and challenging
missions."
On January 10, Department of Defense
officials paid the ARL researchers a visit to see the JTARV in flight
and up close. You can check it out for yourself in the video below.

scientists have succeeded in squeezing hydrogen so intensely that it
has turned into a metal, creating an entirely new material that might be
used as a highly efficient electricity conductor at room temperatures.
Abstract
Producing
metallic hydrogen has been a great challenge to condensed matter
physics. Metallic hydrogen may be a room temperature superconductor and
metastable when the pressure is released and could have an important
impact on energy and rocketry. We have studied solid molecular hydrogen
under pressure at low temperatures. At a pressure of 495 GPa hydrogen
becomes metallic with reflectivity as high as 0.91. We fit the
reflectance using a Drude free electron model to determine the plasma
frequency of 32.5 ± 2.1 eV at T = 5.5 K, with a corresponding electron carrier density of 7.7 ± 1.1 × 1023 particles/cm3,
consistent with theoretical estimates of the atomic density. The
properties are those of an atomic metal. We have produced the
Wigner-Huntington dissociative transition to atomic metallic hydrogen in
the laboratory.

China coming up with USD 18.8 million Gravitational waves observatory near Actual Control with India
China will set up world's highest altitude gravitational wave telescopes with a budget of USD 18.8 million close to the Actual Control with India.

The highest altitude gravitational wave telescopes in the world with a budget of USD 18.8 million will be set up close to the Actual Control with India.
The first telescope is already under-construction and has been code-named Ngari No 1, said Yao Yongqiang, chief researcher with the National Astronomical Observatories of the Chinese Academy of Sciences. Yongqiang further said that the first telescope is being set up 30 km south of Shiquanhe Town in Ngari Prefecture.
Parts of Nagri is last Tibetan prefecture at China's border with India.
The first telescope is located 5,250 meters above the level of the sea. It will detect and collect precise data on primordial gravitational waves in the Northern Hemisphere.
The telescope is likely to go operational by 2021, state-run Xinhua news agency reported.
In the second phase, a series of telescopes, code-named Ngari No 2 will be located about 6,000 meters above the level of the sea, said Yongqiang.
Yongqiang didn't spoke as to when will the construction of Ngari No 2 begin. There will be only two phases of Ngari gravitational wave observatory the estimated budget for which has been set up at 130 million yuan (USD 18.8 million).
The Institute of High Energy Physics, National Astronomical Observatories, and Shanghai Institute of Microsystem and Information Technology, among others initiated the project, the report said.
Ngari sports high altitude, clear sky and minimal human activity. It is said to be one of the best spots in the world to detect tiny twists in cosmic light.
Yao said the Ngari observatory will be among the world's top primordial gravitational wave observation bases, alongside the South Pole Telescope and the facility in Chile's Atacama Desert.
Albert Einstein's theory of general relativity first proposed the gravitational waves 100 years ago. But it wasn't until 2016 that scientists with the Laser Interferometer Gravitational-Wave Observatory announced proof of the waves' existence, spurring fresh research interest among the world's scientists.
Last September, China commissioned the world's largest radio telescope in a mountainous region of southwest China's Guizhou Province to search for more strange objects space, gain better understand the origin of the universe and to boost the global hunt for extraterrestrial life.
The installation of the telescope's main structure -- a 4,450-panel reflector as large as 30 football pitches was built at unique valley in Guizhou Province.
