Genetically modified 'shortcut' boosts plant growth by 40%

Science
Scientists in the US have engineered tobacco plants that can grow up to 40% larger than normal in field trials. The researchers say they have found a way of overcoming natural restrictions in the process of photosynthesis that limit crop productivity.They believe the method could be used to significantly boost yields from important crops including rice and wheat.The study has been published in the journal Science.

It's expected that agricultural demand will increase globally by 60-120% by the middle of this ce...
Black Friday boosts struggling retailers as sales jump

Black Friday boosts struggling retailers as sales jump

Business
Strong Black Friday sales helped tills ring in November - a crucial Christmas trading month that Sports Direct tycoon Mike Ashley had described as "the worst in living memory" for the high street. The Office for National Statistics (ONS) reported sales volumes growing by 1.4% compared to the previous month and by 3.6% on an annual basis.Economists had been expecting a month-on-month figure of around 0.3% - given some warnings in the retail sector that Black Friday promotions had largely left consumers - anxious about the outcome of Brexit - feeling cold.The ONS did, however, place a health warning on the contribution from Black Friday saying the evolution of the promotional period was continuing to put a strain on its seasonal adjustment models.It reported that much of the ...
Global warming boosts century-to-century variability, study finds

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 -...
