The most mysterious phenomenon in cosmology – dark energy – may not exist at all, according to Professor Subir Sarkar, head of the particle theory group at the University of Oxford in the UK.
Speedy, affordable water tests that can be used in on location and even run continuously will help scientists identify disease-causing bacteria in under an hour and potentially reduce the spread of common illnesses such as diarrhoea, which kills an estimated 842,000 people every year.
'Invasive and uncomfortable' procedures for detecting if someone has bladder cancer could be replaced by urine tests that not only screen for the presence of the disease but also help doctors choose the right course of treatment for a particular patient.
It was a life-altering event. Around 66 million years ago, at the end of the Cretaceous period, an asteroid struck the Earth, triggering a mass extinction that killed off the dinosaurs and some 75% of all species. Somehow mammals survived, thrived, and became dominant across the planet. Now we have new clues about how that happened.
Newly-discovered genes that helped supersize human brains along with DNA retrieved from extinct humans, which can still be found in people living today, are expanding scientists’ understanding of how our species evolved.
Fathers’ hormone levels and brain activity may change when they spend time with their children, helping them adapt to parenthood in a way that has been overlooked until now, according to Professor Marian Bakermans-Kranenburg, who studies children and family relations at Vrije Universiteit Amsterdam and was until recently at Leiden University in the Netherlands. She is conducting a series of studies with new fathers, to investigate the role that hormones can play in how they bond with their children.
The impact of heavy droughts, heatwaves and cold spells on energy demand and supplies would be lessened with seasonal climate forecasts that allow energy companies to better predict spikes in usage ahead of time, researchers say.
Wealth-generating, flat-pack solar houses and a profit-sharing scheme that incentivises retrofitting are bringing sustainable living to people who would otherwise not be able to afford it.
New observations may provide alternative explanations for dark energy.
The technology could work with existing infrastructures, says Prof. Lee Cronin
We need to double-check the evidence on dark energy, as it may not exist at all, says Prof. Subir Sarkar.
