WASHINGTON, Nov. 21 (Xinhua) -- Astronomers from the U.S. and Europe said Thursday they had observed the brightest gamma-ray burst (GRB) ever recorded in the relatively nearby universe, a finding that could lead to a rewrite of standard theories on how the blast occurs. The event, named GRB 130472A, was observed by several space- and ground-based telescopes on April 27. The findings were reported in four papers published by the U.S. journal Science. "We suddenly saw a gamma-ray burst that was extremely bright -- a monster gamma-ray burst," astrophysicist Daniele Malesani of the University of Copenhagen, Denmark, said in a statement. "This is one of the most powerful ...

Nov. 15, 2013 — New research has found that the number of pests and disease outbreaks in trees and forests across the world has been increasing. Share This:The review "The consequences of Tree Pests and Diseases for Ecosystem Services" by scientists from the universities of Southampton, Cambridge, Oxford and St Andrews is published today (15 November) in the journal Science. The research shows that the experience of widespread death of trees, similar to that seen from Dutch elm disease and with the arrival last year of the new fungal disease of ash -- Chalara fraxinea -- has not been unique to the UK. Furthermore, there is growing concern that aspects of globalisation -- ...

science Alert:The gene could help in the development of a more digestible sorghum. IUniversity of Queensland scientists have identified a sorghum gene which could lead to development of more digestible feedstocks for farm animals and much-improved nutrition for some of the world’s poorest nations. Known around the world for its drought-tolerance and florid heads of grain at harvest time, a more digestible sorghum would allow better uptake of vital nutrients. For people living on marginalised farmland and dependent on sorghum as a fodder or food crop, these findings could prove to be life-saving, while also maximising water and land-use efficiency.

An international team of astronomers has answered a long standing question about the enigmatic jets emitted by black holes, in research published in the journal Nature. Jets are narrow beams of matter spat out at high speed from near a central object, like a black hole "Although they have been observed for decades, we're still not sure what they are made of, or what powers them," ESO astronomer Dr Maria Diaz Trigo, lead author of the study, said. The team studied the radio waves and X-rays emitted by a small black hole a few times the mass of the Sun. The black hole in question was known to be active, but the team's radio observations did not show any jets, and ...

A San Diego start-up company called Organovo has managed to use 3D printing to generate a liver that lasts for 40 days. The company is lighting the way for 3D printed organs and edible meat of the future after developing a slice of functioning liver by printing layers of liver cells. As the liver is an organ that naturally regenerates itself, it makes it perfect for this project and Organovo's lastest printed liver was fully functioning for 40 days, which was a 700 per cent increase on the company's previous effort last April that lasted five days. The 3D printed liver filters out toxins and drugs to keep in nutrients, but the company has yet to master the ability to integrate ...

Unprecedented in terms of duration era of global economic stagnation continues. To break out of it, the world needs a powerful "kick" in the form of a landmark scientific discovery, for example, radical life extension. In the 20th century, scientists believed that soon they would find a theoretical path to immortality of humans. In the 21st century this research is forgotten. Why has it happened? A few days ago, on October 10 in Stockholm Peter Higgs and Francois Engler were awarded the Nobel Prize for theoretical justification of the existence of the boson, a particle that allows other elementary particles to acquire mass.

WASHINGTON (AP) — Space is vast, but it may not be so lonely after all: A study finds the Milky Way is teeming with billions of planets that are about the size of Earth, orbit stars just like our sun, and exist in the Goldilocks zone — not too hot and not too cold for life. Astronomers using NASA data have calculated for the first time that in our galaxy alone, there are at least 8.8 billion stars with Earth-size planets in the habitable temperature zone. The study was published Monday in the journal Proceedings of the National Academy of Science. For perspective, that's more Earth-like planets than there are people on Earth. As for what it says about the odds that there ...

ScienceDaily: Nov. 1, 2013 — It was once thought that each cell in a person's body possesses the same DNA code and that the particular way the genome is read imparts cell function and defines the individual. For many cell types in our bodies, however, that is an oversimplification. Studies of neuronal genomes published in the past decade have turned up extra or missing chromosomes, or pieces of DNA that can copy and paste themselves throughout the genomes. Share This: ? The only way to know for sure that neurons from the same person harbor unique DNA is by profiling the genomes of single cells instead of bulk cell populations, the latter of which produce an average.
