Global warming boosts century-to-century variability, study finds

Science
Oct. 12 (UPI) -- As Earth gets hotter, century-to-century climate variability increases, according to a new study. When scientists compared the century-scale climate variability during the last interglacial period, between 130,000 and 115,000 years ago, with variability during the last 11,700 years, they found a significant correlation between warming and variability. During the last interglacial, or Eemian stage, the planet experienced significant Arctic warming. The average global temperature was between 3 and 11 degrees Celsius warmer than the pre-industrial average. In other words, Earth was about as warm as climate scientists expect the planet to get by the end of the century -- should global warming continue unabated. Earth not only experienced higher temperatures during the last i...
Stress triggers white blood cells, boosts heart attack risk for diabetics

Stress triggers white blood cells, boosts heart attack risk for diabetics

Health
June 26 (UPI) -- Stress hormones and white blood cells can be good or bad -- they can join together to fight infection and heal injuries, but they also can lead to heart attacks. Researchers at the University of Pittsburgh School of Medicine studied how white blood cells can rupture and hemorrhage in people with diabetes, because they are overactive, and cause inflammation in plaques in blood vessels. Findings from the new study were published Tuesday in the journal Immunity. "If the rupture occurs in the coronary artery, the person has a heart attack. If the rupture occurs in the carotid artery, it causes a stroke," Dr. Partha Dutta, an assistant professor of medicine at Pitt's School of Medicine, said in a press release. There are more than 100 million adults in the United States livin...
'Feel good' factor not CO2 boosts global forest expansion

'Feel good' factor not CO2 boosts global forest expansion

Science
Forests are increasing around the world because of rising incomes and an improved sense of national wellbeing say researchers.The authors refute the idea that increasing levels of CO2 in the atmosphere are the key cause of the spread of trees. As countries become better off, farmers focus on good quality soils and abandon marginal lands, the authors say.As a result, trees are able to rapidly reforest these deserted areas.The study highlights the fact that between 1990 and 2015 forest growing stock increased annually by 1.31% in high income countries and by 0.5% in middle income nations, while falling by 0.72% in 22 low income countries. Several global climate models have attributed this change to what's termed CO2 fertilisation -...
Keeping livers 'alive' boosts transplant success, trial finds

Keeping livers 'alive' boosts transplant success, trial finds

Health
Keeping donated livers "alive" with a machine prior to transplants boosts the chances of a successful operation, a landmark trial has found.Usually livers are kept in ice prior before the surgery, but many become damaged and unusable as a result. For this study, scientists put them in a perfusion machine, pumping the organs with blood, nutrients and medicines.More of these "warm" livers went on to be transplanted and showed less damage than the "cold" ones, the trial found.Scientists said the study could help to reduce the significant proportion of people who die waiting for a new liver and potentially "transform" how organ transplants are carried out. Record number of organ donors in 2017'Warmed liver' transplant first'Major impact'The randomised controlled trial involved 222 liver tran...
World's biggest miner BHP's half-year profit jumps 25 percent, boosts dividend

World's biggest miner BHP's half-year profit jumps 25 percent, boosts dividend

Finance
The world's biggest miner BHP Billiton reported a 25 percent rise in underlying half-year profit on Tuesday, helped by robust metals prices, and said its focus remains on cutting debt and boosting shareholder returns.BHP said its plan to sell its onshore U.S. shale assets, which it has in its books at $ 14 billion, was progressing to plan with initial bids expected in the June quarter.It also brushed off calls by activist investor Elliott Advisors to change its structure, with listings in both Britain and Australia, saying that the costs and risks of collapsing the dual listed structure outweigh potential benefits.Underlying profit for the half year ended Dec. 31 rose to $ 4.05 billion from $ 3.24 billion a year ago, below a forecast of $ 4.30 billion, according to Thomson Reuters I/B/E/S....
