‘No matter how bad, it is always fixable’: how Bea Elton cleans up the houses – and lives
She has built an unlikely career in mould, maggots and excrement, cleaning for those who most need it. It can take months building trust with a stranger, before she and her boyfriend go in and transform everything‘There might be a dead bird in the box room. We think it has been t
Scientists discover a hidden heart valve risk linked to gum disease
Researchers found that bacteria linked to gum disease may help drive the development of calcific aortic valve stenosis by triggering inflammation and calcium buildup in the heart valve. The early findings suggest that keeping gums healthy could play a role in reducing the risk of
RNA-only repair enzyme reveals how primordial life could have protected genomes
In most modern cells, DNA stores the genetic blueprint, and proteins replicate, repair and build from those blueprints. At the same time, proteins require instructions from DNA to be made in the first place.
A 200-year-old physics experiment could help build future computers
Scientists at Nanyang Technological University in Singapore have discovered a surprisingly simple way to create exotic light structures called optical skyrmions using a 200-year-old optical effect known as the Poisson spot. Instead of relying on expensive, highly engineered mater
What one of Emperor Hadrian's latrines is telling us about the durability of Roman concret
One of the many marvels of the Roman world is that some of its buildings are still with us. But why have they lasted for so long when some relatively modern structures are in a state of decay after a few decades?
New technique for building ultra-thin material stacks promises quantum breakthrough
Scientists have unveiled a new fabrication technique for the ultra-clean manufacturing of 2D heterostructures—materials just a few atoms thick—that could be used in quantum technology and electronics. Experts from Southampton and Singapore say the method could be used to develop
Astronomers uncover the earliest known signs of galaxy-building in action
Astronomers at Durham University have made a major advance in understanding how galaxies formed and evolved in the early universe. Using powerful new observations, the team discovered the most distant example ever found of a compact, star-forming structure at the heart of a galax
New cases slow in NYC Legionnaires' disease outbreak; Met museum among buildings with posi
A Legionnaires' disease outbreak in a New York City neighborhood now counts 60 cases, but new diagnoses are slowing, health officials said Tuesday. They reported progress on inspections for the disease-causing bacteria—finding traces in dozens of buildings including the famed Met

England risks building new ‘death traps’ as experts warn of overheating crisis
Vulnerable people more at risk as research finds only half of local authority plans require cooling strategiesEngland risks constructing a new generation of “death trap” buildings that can fatally overheat unless the government tightens standards and prioritises climate safeguards, planning experts have said.Fears are growing about the plight of vulnerable people in heatwaves, with research this week suggesting that 2,700 people had died in the May and June heatwaves in England and Wal
