Oil prices flutter around even in light trading

Business
Jan. 15 (UPI) -- Light trading on the U.S. federal holiday left crude oil prices around neutral, but still marching closer to $ 70 per barrel, potentially on geopolitical risk.Markets in the United States are closed as the nation commemorates the legacy of civil rights leader Martin Luther King Jr.On Friday, markets wavered but eventually rallied after U.S. President Donald Trump decided to extend a waiver on oil-related sanctions for Iran under the terms of the multilateral Joint Comprehensive Plan of Action. The president must regularly weigh sanctions and not extending them would've pulled the estimated 1 million barrels of Iranian oil flowing in the global market, and inevitably led to the end of the agreement.On its face, the wavier would've sent oil prices lower because it left Irani...
Light shed on mystery space radio pulses

Light shed on mystery space radio pulses

Science
Astronomers have shed more light on a mysterious source of recurring radio pulses from space.Fast radio bursts are one of the most persistent puzzles in astronomy; while usually short-lived, one source in the sky was sending out repeated flashes.Now, a team says the strange emission could be caused by a dead star with an exceptionally powerful magnetic field.Details were reported here at the 231st American Astronomical Society meeting.The first FRB was discovered in 2007, in archived data from the Parkes Radio Telescope in Australia. Astronomers were searching for new examples of magnetised neutron stars called pulsars, but found a new phenomenon - a radio burst from 2001. Since then, 18 FRBs - also referred to as "flashes" or "sizzles" - have been found in total.But only one of these sour...
UV light could foil the fungus causing white-nose syndrome in bats

UV light could foil the fungus causing white-nose syndrome in bats

Science
Jan. 2 (UPI) -- Scientists believe they've discovered the Achilles heel of the fungus that causes white-nose syndrome, a disease devastating bat populations across North America. New research suggests the fungus can't survive significant doses ultraviolet light.To better understand the pathogen, researchers with the U.S. Forest Service, U.S. Department of Agriculture and the University of New Hampshire compared the fungus, Pseudogymnoascus destructans, to six of its non-pathogenic relatives.Their analysis showed the fungus failed to repair DNA damage caused by exposure to UV light. The discovery -- detailed this week in the journal Nature Communications -- could inspire new treatments for the deadly bat disease."This research has tremendous implications for bats and people," Tony Ferguson,...
Fossilised eggs shed light on reign of pterosaurs

Fossilised eggs shed light on reign of pterosaurs

Science
The largest clutch of pterosaurs eggs ever discovered suggests that the extinct flying reptiles may have gathered together in vast colonies to lay their eggs.More than 200 eggs were discovered at one location in China.Little is known about how the pterosaurs reproduced.The find suggests that hatchlings were probably incapable of flight when they emerged from the egg, and needed some parental care.Predator attackFossilised pterosaur eggs and embryos are extremely rare. Until now only a handful of eggs have been found, in Argentina and north-western China.The large collection of eggs suggests pterosaurs may have nested in colonies, where they defended their offspring from predator attack.Pterosaur experts Xiaolin Wang of the Institute of Vertebrate Palaeontology and Paleoanthropology in Beij...

Budget 2017: Green light for driverless car testing

Business
The testing of driverless cars on UK roads is expected to be given the green light in Wednesday's Budget.Chancellor Philip Hammond will announce regulation changes to allow developers to apply to test the vehicles.Writing in the Sun, he said investment would "prepare the ground" for the cars to be on roads by 2021.Mr Hammond is also reportedly planning to announce proposals to build 300,000 new homes in the UK a year, as well as extra money for NHS nurses' pay.The chancellor has also promised to investigate why some developers and speculators are holding on to land instead of building on it. In an interview with the Sunday Times, Mr Hammond said the government would do "whatever it takes" to fix the housing market, including underwriting loans to small house builders if necessary.Mr Hammon...
