A latest research has backed evidence that a simple blood test could be used to detect concussions someday. It suggested that a protein associated with head trauma could be present in blood till seven days post injury, which may be helpful in diagnosing patients who get late in looking for treatment.

The study included patients from a Florida hospital, and the results are preliminary. They suggested that a concussion blood test on the basis of the two studied proteins or on other so-called biomarkers under evaluation can be possible just some years away from regular use.

South Korean researchers have conducted a study after they discovered some interesting signs that Antarctic seabirds may remember and recognize humans even after meeting them just a few times.

The Christian Science Monitor reported that it’s not strange for intelligent bird species to be able to remember interactions with humans. It is due to this reason that they can easily understand why they can recognize people. Known among the most intelligent bird species, crows are apt examples of creatures that will certainly recognize you from the time they have seen you.

The more we understand about dwarf planet Pluto, the more confusing it becomes. New set of data sent by NASA’s New Horizons spacecraft revealed that the distant planet had lakes on its surface in the past. Before this, it was thought that Pluto only has an ocean under its frozen surface.

The data collected by the spacecraft during its flyby of Pluto last year in July also suggested that the planet in the Kuiper belt may have a nitrogen lake on its surface in future. NASA has released a new image confirming that there were liquid channels on the surface of Pluto millions or billions of years ago.

After 20,000 feet high ash plume created Monday by a volcanic eruption in Alaska, the local authorities raised alert level. The volcanic event led to the grounding of certain flights and curbs on travel by road to western and northern parts of the state. Strong winds pushed the ash cloud, which rose to 20,000 feet, into the heart of the state.

Named Pavlof Volcano, it is one of Alaska’s most active volcanoes, which erupted about 4 p.m. Sunday in the 8,261-foot mountain. The site is some 625 miles southwest of Anchorage on the Alaska Peninsula, the finger of land that sticks out from mainland Alaska toward the Aleutian Islands. Geologists say Pavlof falls in the category of open-system volcano.

An eccentric ‘hot Jupiter’, exoplanet HD 80606b, is orbiting very close to its host star, like a comet. When the exoplanet comes close to its star, its temperature rises and reaches an extreme level, found a team of researchers using NASA’s Spitzer Space Telescope.

While orbiting the star, HD 80606 follows an oblong route instead of a circular path. The hot Jupiter goes away from its host star for more than 111 days. After that, in less than one day, it comes very close to the host star before moving back again. When it comes closer to its host star, the exoplanet gets huge amount of energy from the star. The planet’s side that faces the star while approaching it becomes very hot. Temperature of that side reaches about 2,000 degrees Fahrenheit, as per the researchers.

Last month, Japanese space agency JAXA launched an X-ray astronomical satellite into space in an attempt to understand the high-energy universe in gamma rays and X-rays. The satellite, Hitomi, also known as ASTRO-H and New X-ray Telescope, is no more in contact with mission controllers on earth.

JAXA officials announced on Saturday that the agency officials are trying to understand what happened to the astronomy telescope. “Communication with the X-ray Astronomy Satellite "Hitomi" (ASTRO-H), launched on February 17, 2016 (JST), failed from the start of its operation originally scheduled at 16:40, Saturday March 26 (JST)”, said the agency in a statement.

The satellite’s current state is unknown, but the team is working to find the cause of communication failure, said JAXA.
