NASA's Webb Telescope will use quasars to unlock the secrets of the early universe
Quasars are very bright, distant and active supermassive black holes that are millions to billions of times the mass of the Sun. Typically located at the centers of galaxies, they feed on infalling matter and unleash fantastic torrents of radiation. Among the brightest objects in the universe, a quasar's light outshines that of all the stars in its host galaxy combined, and its jets and winds...

Researchers find 3,000-year-old shark attack victim
Newspapers regularly carry stories of terrifying shark attacks, but in a paper published today, Oxford-led researchers reveal their discovery of a 3,000-year-old victim—attacked by a shark in the Seto Inland Sea of the Japanese archipelago.
ATLAS experiment measures top quark polarization
Unique among its peers is the top quark—a fascinating particle that the scientific community has been studying in detail since the 90s. Its large mass makes it the only quark to decay before forming bound states (a process known as hadronisation) and gives it the strongest coupling to the Higgs boson. Theorists predict it may also interact strongly with new particles—if it does, the Large...

Archaeologists have provided important new evidence to answer the question 'who exactly were the Anglo-Saxons?' New findings based on studying skeletal remains clearly indicates the Anglo-Saxons were a melting pot of people from both migrant and local cultural groups and not one homogenous group from Western Europe.

Odd smell: Flies sniff ammonia in a way new to science
The stink of ammonia in urine, sweat, and rotting meat repels humans, but many insects find ammonia alluring. Now, UConn researchers have figured out how the annoying insects smell it, a discovery that could lead to better ways to make them buzz off.
Wild bees need deadwood in the forest
How many tree species are there in the forest? How are the trees scattered throughout? How high are the individual tree crowns? Are there fallen trees or hollowed-out tree trunks? Forest scientists characterize forests according to structural factors. "Structural richness is very important for biodiversity in forests. But forests used for forestry are generally poor in terms of structure," says...
