Stellar death reveals compact neutron star binary

Science
Oct. 12 (UPI) -- Astronomers were surprised when the collapse of a massive star yielded a rather puny supernova. An investigation of the phenomena suggests a companion star robbed the collapsing star of much of its stellar material, limiting the magnitude of the explosion. "We saw this massive star's core collapse, but we saw remarkably little mass ejected," Kishalay De, grad student at the California Institute of Technology, said in a news release. "We call this an ultra-stripped envelope supernova and it has long been predicted that they exist. This is the first time we have convincingly seen core collapse of a massive star that is so devoid of matter." When massive stars run out of fuel and collapse in on themselves, the material rebounds outward in dramatic fashion. The violent explos...
MUSE data reveals hydrogen reservoirs around earliest galaxies

MUSE data reveals hydrogen reservoirs around earliest galaxies

Science
Oct. 1 (UPI) -- Astronomers have discovered an abundance of Lyman-alpha radiation in Hubble Ultra-Deep Field. The data -- collected by the MUSE spectrograph on ESO's Very Large Telescope -- suggests the universe's earliest galaxies were surrounded by large reservoirs of hydrogen. The Hubble Ultra-Deep Field is a small, dark region of the night sky home to a large concentration of ancient galaxies. The field is home to thousands of the cosmos' earliest galaxies, as they appeared just a few hundred million years after the Big Bang. The field's light spent 12 billion years traveling to Hubble's lens. Lyman-alpha emission, or radiation, is the spectral line of hydrogen. As revealed by the spectrographic data collected by MUSE, the early universe was saturated by Lyman-alpha emission. "Realiz...

Actress Claire Foy reveals struggles with anxiety

Entertainment
Actress Claire Foy has opened up about her struggles with anxiety, revealing how her career worsened her condition. In an interview with the Guardian the 34-year-old said she had suffered anxiety since she was a child but it "exploded" when she became an actress.Foy recently won an Emmy for her role as Queen Elizabeth II in the Netflix series The Crown. But the star admitted the condition meant she doubted her ability and was plagued by negative thoughts."When you have anxiety, you have anxiety about - I don't know - crossing the road," she told the Guardian's Weekend magazine."The thing about it is, it's not related to anything that would seem logical. It's purely about that feeling in the pit of your stomach, and the feeling th...
558-million-year-old fat molecule reveals world's earliest animal

558-million-year-old fat molecule reveals world's earliest animal

Science
Sept. 20 (UPI) -- Scientists have discovered a fat molecule preserved in a 558-million-year-old fossil. According to a new paper published this week in the journal Science, the discovery confirms Dickinsonia, a strange blob-like sea creature, as the earliest animal in the geologic record. Dickinsonia is a member of the Ediacaran biota, a group of primitive organisms with frond-like patterns. The group emerged during the Ediacaran period, which lasted from 635 to 542 million years ago. Scientists have previously argued whether Ediacaran species were animals. The fat molecule -- a type of cholesterol unique to animals -- found within the Dickinsonia fossil suggests they were. "The fossil fat molecules that we've found prove that animals were large and abundant 558 million years ago, millio...

Blood taken from a young person could be the key to maintaining long-lasting health in old age, scientists claim. Blood factors obtained from young beings can improve late-life health in animals, the study published in Nature journal revealed.It could also help reduce the chances of developing age-related diseases, the scientists at University College London (UCL) said.Dame Linda Partridge, a geneticist at UCL, said research shows that young blood could allow humans to live a life free of diseases such as cancer and heart disease right up until their deaths."I would say ageing is the emperor of all diseases," she told The Times."A lot of people regard ageing as 'natural' and that therefore you shouldn't interfere with nature. But we've always considered it an ethical impera...
