#Scientists reveal how stem cells defend against viruses Scientists from the Institute of Molecular and Cell biology (IMCB), a research institute under the Agency for Science, Technology and Research (A*STAR),

For more than 100 years, researchers have inferred how atoms are arranged in three-dimensional space using a technique called X-ray crystallography,
Heat from the top of your head radiates into space as infrared light. Now three Stanford engineers have developed a technology that improves on solar panel performance by exploiting this basic phenomenon.
Their invention shunts away the heat generated by a solar cell under sunlight and cools it in a way that allows it to convert more photons into electricity.
The material is transparent to the visible sunlight that powers solar cells, but captures and emits thermal radiation,
"Solar arrays must face the sun to function, even though that heat is detrimental to efficiency, "Fan said."
"Our thermal overlay allows sunlight to pass through, preserving or even enhancing sunlight absorption, but it also cools the cell by radiating the heat out
and improving the cell efficiency.""A cool way to improve solar efficiency In 2014, the same trio of inventors developed an ultrathin material that radiated infrared heat directly back toward space without warming the atmosphere.
They presented that work in Nature, describing it as"radiative cooling "because it shunted thermal energy directly into the deep, cold void of space.
In their new paper, the researchers applied that work to improve solar array performance when the sun is beating down.
The Stanford team tested their technology on a custom-made solar absorber--a device that mimics the properties of a solar cell without producing electricity--covered with a micron-scale pattern designed to maximize the capability to dump heat
in the form of infrared light, into space. Their experiments showed that the overlay allowed visible light to pass through to the solar cells,
but requires the preservation of the visible spectrum of sunlight for either practical or aesthetic reasons."

The results of the METEOR trial indicate that cabozantinib is able to shrink tumours and slow down tumour growth much better than current standard treatment in patients who previously received VEGFR-targeted drugs.
"An early evaluation of overall survival from the ongoing METEOR trial has shown a strong trend indicating that survival may be improved in patients receiving cabozantinib compared to standard therapy.
Patients recruited to the METEOR clinical trial, which started in June 2013, were randomised to receive either 60 mg a day of cabozantinib in tablet form,

A team of international scientists used several of the world's most powerful telescopes to study the energy of the universe
"We used as many space -and ground-based telescopes as we could get our hands on to measure the energy output of over 200,000 galaxies across as broad a wavelength range as possible,"Galaxy And Mass Assembly (GAMA) team leader Simon Driver,
of the University of Western australia, said in a statement. The astronomers created a video explaining the slow death of the universe to illustrate the discovery.
When the Big bang created the energy of the universe about 13.8 billion years ago, some portion of that energy found itself locked up as mass.
When stars shine they are converting that mass back into energy, as described by Albert Einstein's famous equation E=mc2 (energy=mass x speed of light squared).
additional energy is constantly being generated by stars as they fuse elements like hydrogen and helium together,
either by dust as it travels through the host galaxy, or escapes into intergalactic space and travels until it hits something,
such as another star, a planet, or, very occasionally, a telescope mirror.""Astronomers have known that the universe is slowly fading out since the late 1990s.
Using several telescopes on the ground, as well as NASA's orbiting GALEX and WISE and the European space agency's Herschel,
the team found that the energy output is dropping over 21 different wavelengths, making their results the most comprehensive assessment to date of the energy output of the nearby universe."
"The universe will decline from here on in, sliding gently into old age, "Driver said d

#Star Pair#s Dusty Disk Shines Light on Planet formation Astronomers using the Gemini South telescope in Chile have discovered striking new evidence for planet formation in a dusty disk surrounding
a pair of stars in Sagittarius. The team took advantage of an offering for Early Science using the Gemini Planet Imager to study infrared light scattered off dust grains in the disk around the binary system V4046 Sgr.

The coronagraph is represented by the black filled circles. he Gemini Planet Imager allows us to study nearby planet forming disks in sufficient detail that we can obtain direct-image evidence for young planets in orbits similar to those of the giant planets
in our own solar system, says Valerie Rapson of the Rochester Institute of technology, who led the research team.
the GPI imaging reveals an intriguing double ring structure around the V4046 Sgr binary that is most likely due to the formation of a giant planet
(or planets) at some 4-12 times the Earth-Sun distance (approximately between Jupiter and Uranus,
if orbiting our Sun). his is perhaps the best such evidence yet for planet formation so close to a binary system,

#Astronomers discover powerful aurora beyond solar system Astronomers have discovered the first aurora ever seen in an object beyond our Solar system.
The aurora similar to the famous orthern Lightson Earth is 10,000 times more powerful than any previously seen.
They found the aurora not from a planet, but from a low-mass star at the boundary between stars and brown dwarfs.
The discovery reveals a major difference between the magnetic activity of more-massive stars and that of brown dwarfs and planets,
the scientists said. ll the magnetic activity we see on this object can be explained by powerful auroras,
his indicates that auroral activity replaces solar-like coronal activity on brown dwarfs and smaller objects,
The astronomers observed the object, called LSR J1835+3259, using the Karl G. Jansky Very Large Array (VLA) at radio wavelengths,
along with the 5-meter Hale Telescope on Palomar Mountain and the 10-meter Keck Telescope in Hawaii at optical wavelengths.
18 light-years from Earth, has characteristics unlike any seen in more-massive stars. Brown dwarfs, sometimes called ailed stars,
are objects more massive than planets, yet too small to trigger the thermonuclear reactions at their cores that power stars.
The astronomers said their observations of LSR J1835+3259 indicate that the coolest stars and brown dwarfs have outer atmospheres that support auroral activity,
rather than the type of magnetic activity seen on more-massive and hotter stars. The discovery also has implications for studying extrasolar planets.
The aurora the scientists observed from LSR J1835+3259 appears powered by a little-understood dynamo process similar to that seen on larger planets in our Solar system.
This process is different from that which causes the Earth auroral displays the planet magnetic field interacting with the solar wind. hat we see on this object appears to be the same phenomenon wee seen on Jupiter, for example,
but thousands of times more powerful, Hallinan said. his suggests that it may be possible to detect this type of activity from extrasolar planets,
many of which are significantly more massive than Jupiter, he added e

#Perseid meteors to light up summer skies The evening of Wednesday 12 august into the morning of Thursday 13 august sees the annual maximum of the Perseid meteor shower.
This year, a new moon makes prospects for watching this natural firework display particularly good. A Perseid seen in August 2010 above the four enclosures of the European Southern Observatory Very Large telescope at Paranal, Chile.
Credit: ESO/S. Guisard. Meteors (popularly known as hooting stars are the result of small particles,
some as small as a grain of sand, entering the Earth atmosphere at high speed.
The tail of the Comet Swift-Tuttle, which last passed near the Earth in 1992, leaves such debris in the Earth path.
On entering the atmosphere, these particles heat the air around them, causing the characteristic streak of light seen from the ground.
This shower of meteors appears to originate from a single point, called a adiant in the constellation of Perseus, hence the name.
The shower is active each year from around 17 july to 24 august although for most of that period only a few meteors an hour will be visible.
From the UK, the peak of the shower occurs in the late evening on 12 august to the morning of 13 august,
when as many as 100 meteors or more may be seen each hour. This year, for the first time since 2007, this peak coincides with a new moon on 14 august,
creating ideal dark sky conditions for meteor-spotting. Perseid shooting star near the Pleiades over Woodingdean, Sussex, on the early morning of the 13th,august 2013.

The french astronomer Jeremie Vaubaillon has predicted also that the Perseids may this year produce an outburst of activity around 7. 40pm BST on 12th august.
Although it is unfortunately still daylight at that time in the UK and Ireland, it is just possible that enhanced rates may persist for a few hours around this time
and so be observable soon after dark. nlike many celestial events meteor showers are straightforward to watch,
and for most people the best equipment to use is simply the naked eye. Advice from experienced meteor observers is to wrap up well and set up a reclining chair to allow you to look up at the sky in comfort.
If possible it also helps to be in a dark place away from artificial light, and to have unobstructed an view of the sky.
Although the number of visible meteors is hard to predict accurately, at least one every few minutes can be expected.
their trajectories are bent into circular orbits, causing them to loop around and around. The higher the magnetic field, the tighter a particle orbit becomes.
