Researchers find honey bee gene that causes virgin birth

Researchers find honey bee gene that causes virgin birth

Science
May 7 (UPI) -- The Cape honey bee, a subspecies found along the southern coast of South Africa, reproduces without having sex. Now, scientists have identified the gene responsible for the bee's virgin births. Scientists found the gene, named GB45239, on the bee's eleventh chromosome. The discovery, detailed this week in the journal Current Biology, ends a 30-year search for the virgin birth gene. Analysis of the novel gene could help scientists gain new insights into the evolution of different reproductive strategies. "Sex is a weird way to reproduce and yet it is the most common form of reproduction for animals and plants on the planet," study co-author Benjamin Oldroyd, professor of behavioral genetics at the University of Sydney in Australia, said in a news release. "It's a major biol...

Actress Shirley Knight dies of natural causes at age 83

Entertainment
April 22 (UPI) -- Shirley Knight died on Wednesday of natural causes in the home of her daughter, Kaitlin Hopkins. She was 83. Hopkins posted on Facebook that she was by her mother's side when she passed, having brought her to Texas 26 days prior. Hopkins indicated that Knight had declined after a surgery, and had hospice assistance in her final days. Friends, family and colleagues of Knight's sent video messages sharing their memories, which Hopkins is keeping. The Knight family -- including Hopkins and her half sister Sophie C. Hopkins -- created the Shirley Knight Memorial Fund at Texas State University to help young artists attend school. Knight appeared in films from an uncredited role in 1955's Picnic to playing Kevin James's mother in the two Paul Blart: Mall Cop films. Highlight...
Complex causes behind Arctic greening, researchers say

Complex causes behind Arctic greening, researchers say

Science
Jan. 31 (UPI) -- The greening of the Arctic is one of the most visible effects of climate change, but new research suggests the reasons for the phenomena are surprisingly varied and complex. As satellite images have revealed, snow is melting earlier each year, allowing the plants that comprise the Arctic tundra to put out leaves earlier in the spring. Plants are getting thicker and taller, and vegetation is expanding into previously barren pars of the Arctic. Early efforts to document the phenomena were relatively crude, but new satellite and drone technologies have helped scientists analyze Arctic greening in greater detail. "New technologies including sensors on drones, planes and satellites, are enabling scientists to track emerging patterns of greening found within satellite pixels t...

Lion Air families told of fatal Boeing 737 crash causes

Business
Mechanical and design problems with the flight control system were among the causes of last year's Lion Air crash, families of the victims have been told.Indonesian investigators focused on a system used to improve handling and prevent stalling on the Boeing 737 Max, which crashed killing 189 people.The 737 Max model was grounded after an Ethiopian Airlines crash in March 2019.On Tuesday, Boeing's Kevin McAllister was ousted, the most senior executive to go in the wake of the crashes.Boeing did not comment ahead of formal publication of the report into the Lion Air crash, which took place 13 minutes after take-off from Jakarta on 29 October.The US company's third-quarter results, due later on Wednesday, are expected to be dominated by the fall-out from th...
Obesity ’causes more cases of some cancers than smoking’

Obesity ’causes more cases of some cancers than smoking’

Health
Obesity now causes more cases of four common cancers in the UK than smoking, according to a charity.Cancer Research UK says bowel, kidney, ovarian and liver cancers are more likely to have been caused by being overweight than by smoking tobacco.It says millions are at risk of cancer because of their weight and that obese people outnumber smokers two to one.But its new billboard campaign highlighting the obesity-cancer risk has been criticised for fat-shaming. It is not the first time the charity has been accused of fat-shaming.In February, comedian and campaigner Sofie Hagen took to Twitter to criticise the campaign.One Twitter user, @KenLynch73, said linking obesity with cigarette-style branding was a new low. ...
