A new joint analysis of data has found no conclusive evidence of primordial gravitational waves, despite earlier reports of a possible detection.

A new study has recently revealed that HIV relies on unique immune proteins to enter the brain, which penetrates the brain blood-brain barrier.

Although it was known that HIV can enter the brain early during infection, causing inflammation and memory/cognitive problems, exactly how this occurs has been largely unknown. new solves this mystery by showing that HIV relies on proteins expressed by a type of immune cell, called “mature monocytes,” to enter the brain.

A new research has revealed that fewer viral relics in human genes may be due to a less bloody evolutionary history.

A team of researchers from the University of Oxford and Plymouth University found that humans have fewer remnants of viral DNA in their genes compared to other mammals may be because of reduced exposure to blood-borne viruses as humans evolved to use tools rather than biting during violent conflict and the hunting of animals.

Say goodbye to good old needles, as scientists have found on new method to measure blood sugar with help of light sensor, which doesn’t involve taking the blood.

The bulk of rocks on the surface of Mars look similar to the ‘Black Beauty’ meteorite found a few years ago in the Moroccan desert, a new study suggests.

The meteorite NWA 7034 has been shown to be a 4.4 billion-year-old chunk of the Martian crust.

Spectroscopic measurements of the meteorite are a spot-on match with orbital measurements of the Martian dark plains, areas where the planet’s coating of red dust is thin and the rocks beneath are exposed, researchers said.

Researchers have proposed a new fundamental particle which could explain why no one has managed to detect the elusive ‘dark matter’ that makes up 85 per cent of the universe’s mass.

Dark matter is thought to exist because of its gravitational effects on stars and galaxies, gravitational lensing (the bending of light rays) around these, and through its imprint on the Cosmic Microwave Background (the afterglow of the Big Bang).

Despite compelling indirect evidence and considerable experimental effort, no one has managed to detect dark matter directly.

Japan Sunday launched a backup information gathering satellite (IGS), the country`s first launch of this year.

The satellite is equipped with a radar spy instrument capable of peering through clouds, darkness and camouflage to obtain high-resolution imagery of the Earth`s surface. But the satellite`s exact capabilities were not disclosed, Xinhua reported.

The Japan Aerospace Exploration Agency (JAXA) and Mitsubishi Heavy Industries Ltd. launched the spy satellite aboard a H-2A rocket from Tanegashima Space Centre in Kagoshima prefecture.

A team of scientists has identified two new fluorescent tumor-targeting agents that seek and light up brain cancer cells, suggesting they may help neurosurgeons to more accurately localize and completely resect brain tumors.

Researchers at University of Wisconsin School of Medicine and Public Health evaluated two “tumor-selective” fluorescent agents, called CLR1501 and CLR1502, for their ability to differentiate brain tumors from normal brain tissue in mice.

A new analysis has dynamited a much-hyped discovery of primordial “gravitational waves” from the dawn of time.

Despite earlier reports of a possible detection, a joint analysis of data from ESA’s Planck satellite and the ground-based BICEP2 and Keck Array experiments has found no conclusive evidence of primordial gravitational waves.

Scientists revealed that interstellar dust caused more than half of the signal detected by the Antarctica-based BICEP2 experiment. The Planck spacecraft observations were not yet available in March 2014 when the BICEP2 science team made its announcement.

Researchers have developed a new sensor to detect minute levels of mercury in the atmosphere in just 10 seconds.

The new highly sensitive, laser-based instrument provides scientists with a method to more accurately measure global human exposure to mercury, the researchers noted.

“Our instrument has the potential to greatly enhance our understanding of the atmospheric cycling of mercury and increase understanding of the global impact of mercury on human health,” said co-author of the new study Anthony Hynes from University of Miami.

The 4.4 billion year-old Martian meteorite, which was found a few years ago in the Moroccan desert, is a piece of planet’s crust, it has been revealed.

In a new paper, scientists reported that spectroscopic measurements of the meteorite are a spot-on match with orbital measurements of the Martian dark plains, areas where the planet’s coating of red dust is thin and the rocks beneath are exposed.

A new study has recently revealed that world’s marine species are up to nine times likelier to become extinct than formerly thought.

The alarming study by the University of Sheffield, has been said to be the most thorough analysis of marine conservation data yet, comes as campaigners accused the Government of “watering down” plans to protect England’s marine life, the Independent revealed.

Researchers found that up to a quarter of the planet’s well-known marine species, from the Mediterranean monk seal to the Pondicherry shark, are in danger of being wiped out.

Scholars at the University of Sheffield have warned of the increasing risk to marine life of extinction.

Overfishing, pollution, climate change and destruction of habitats like coral reefs are all putting marine life in trouble and academics fear the risk is not being taken as seriously as concerns for the loss of animals and plants which live on land.

NASA’s Cassini mission has recently found that Saturn’s largest moon, Titan, behaves like Venus and Mars when exposed to raw power of solar wind.

The observations suggest that unmagnetized bodies like Titan might interact with the solar wind in the same basic ways, regardless of their nature or distance from the Sun.

Titan is large enough that it could be considered a planet if it orbited the Sun on its own, and a flyby of the giant moon in Dec. 2013 simulated that scenario, from Cassini’s vantage point.
