Astronomers accidentally discover massive galaxy in early universe

Science
Oct. 22 (UPI) -- Astronomers have located evidence of a massive galaxy in the early universe, quelling doubts about the existence of such monstrous galaxies. The discovery was made on accident, they say. While analyzing observations of the distant universe captured by the Atacama Large Millimeter Array, or ALMA, a collection of 66 telescopes in Chile's high desert, scientists spotted a faint blob. Like a ghost, the unexpected glow appeared unconnected to any major cosmic structure. "It was very mysterious because the light seemed not to be linked to any known galaxy at all," lead researcher Christina Williams, an astronomer at the University of Arizona, said in a news release. "When I saw this galaxy was invisible at any other wavelength, I got really excited because it meant that it was...
Physicists discover new stable form of plutonium

Physicists discover new stable form of plutonium

Science
Oct. 18 (UPI) -- Using the European Synchrotron, a team of physicists have identified a new stable form of plutonium. The newly discovered compound exists in a solid state and features an unexpected, pentavalent oxidation state. The discovery, detailed this week in the journal Angewandte Chemie International Edition, was an accident. Researchers originally set out to develop improved methods for preventing nuclear meltdowns and accidents, as well as the scope of the ensuing fallout. To replicate the release and spread of radioactive nuclides into and throughout the environment -- and thus, develop preventative and control strategies -- scientists at the Helmholtz Zentrum Dresden-Rossendorf synthesized and observed the behavior of actinides, a group of metallic elements that are heavy, ra...
Blood scandal teens made pact to discover their killer

Blood scandal teens made pact to discover their killer

Health
A group of teenagers with haemophilia who were infected by contaminated blood made a pact that whoever survived would find out what was killing them, a public inquiry has heard. Stephen Nicholls, now 52, said he is the only one of his friends left alive and he thinks about that "every day".Thousands of people were infected with hepatitis C and HIV from contaminated blood in the 1970s and '80s. Victims are telling a public inquiry how their lives have been ruined.Prime Minister Theresa May said the public inquiry into the contaminated blood scandal "should have taken place earlier". Mr Nicholls was diagnosed with haemophilia when he was one. At the age of eight, in 1976, he started attending Treloar's school for children with dis...
UK scientists discover world’s tallest tropical tree

UK scientists discover world’s tallest tropical tree

Science
Scientists in the UK and Malaysia say they have discovered the world's tallest tropical tree measuring more than 100m (328ft) high. The lofty yellow meranti was spotted in a Borneo rainforest by a team from the University of Nottingham last year. Researchers from the University of Oxford then carried out 3D scans and drone flights to confirm the record. The tree, found in the Danum Valley Conservation Area in Sabah, has been named Menara, which is Malay for tower.Local climber Unding Jami, who scaled the tree with a measuring tape, said it was a "scary and windy" ascent."But honestly the view from the top was incredible. I don't know what to say other than it was very, very, very amazing," he added. ...

Scientists discover new species of exploding ant

Technology
A new species of ant which can detonate its body when threatened has been discovered by scientists. A research team from Austria, Thailand and Malaysia found the insects, Colobopsis explodens, in the rain forest in Borneo.The ants fend off attackers by latching on to enemies and flexing their bodies so violently that they explode, releasing a toxic yellow liquid and killing themselves instantly.The yellow goo is sticky, can be fatal for predators, and is said to smell similar to curry.This tactic is used by minor worker ants to kill or hold off intruders, often to defend the whole colony.Researchers described the species as "particularly prone to self-sacrifice".Image:The 'doorkeeper' ant has a plug-shaped face to barricade nest entrancesIt is rare in nature for individuals to volunta...
