Should uninfected patients accept hepatitis C-infected livers to reduce waiting time?

Should uninfected patients accept hepatitis C-infected livers to reduce waiting time?

Top Story A modeling study by Massachusetts General Hospital investigators finds that the availability of directly-acting antiviral (DAA) drugs to treat hepatitis C virus (HCV) infection could allow the transplantation of livers from HCV-positive donors into HCV-negative recipients without posing undue risk. It is not uncommon for HCV-positive organs to be discarded and not utilized […]

Bright skies at night: The riddle of the nocturnal sun

Bright skies at night: The riddle of the nocturnal sun

Beth Hoeckel By Rebecca Boyle IN THE millennia before street lights and smartphones, humans could, on rare occasions, walk around on a moonless night and see clearly. Looking up, they could see broad luminous patches of light stretching across the sky, which brightened the heavens in all directions as though it were daylight. People could […]

Cocktail umbrellas can save Earth from the Anthropocene

Liz Foster Light Painting Photography/Alamy Stock Photo By Jonathon Keats When naturalist William Bartram explored the south-east of what’s now the US in the early 1770s, he discovered gopher tortoises, sandhill cranes and rivers overflowing with trout and bream. Retracing Bartram’s path in 2007, artist Mark Dion found golfers, retirees and highways jammed with SUVs. […]

Best of 2017: LIGO and Virgo observatories jointly detect black hole collision

Top Story In August, detectors on two continents recorded gravitational wave signals from a pair of black holes colliding. This discovery, announced today, is the first observation of gravitational waves by three different detectors, marking a new era of greater insight and improved localization of cosmic events now available through globally networked gravitational-wave observatories. The […]

Plants use sand armour to break teeth of attacking caterpillars

Plants use sand armour to break teeth of attacking caterpillars

A white-lined sphinx caterpillar (Hyles lineata) devours a sand verbenaEric LoPresti By Jake Buehler Some plants may use an odd, yet simple defensive tactic against insect herbivores: sand. New research suggests that some plants use sand grains as an unappetizing and abrasive armour. Psammophorous (“sand-carrying”) plants have sticky surfaces to which sand adheres. The coating […]

Best of 2017: Creating a digital cure for epilepsy

Top Story Epilepsy is a neurological disorder characterized by unpredictable, recurrent seizures that can pose a risk to a patient’s safety. A team of Rice University engineering students created a machine-learning algorithm that was “very good” at predicting seizures: It predicted all seizures in their dataset at least two minutes before their onset with 3.9 […]

Our lust for tastier chocolate has transformed the cocoa tree

We’ve changed cocoaIngo Arndt / NaturePL By Chris Baraniuk The world loves chocolate, but thousands of years of selective breeding have drastically changed the genome of the trees from which chocolate is made. The plants now produce tastier chocolate, but they also make less due to harmful mutations. The key ingredient in chocolate is cocoa […]

Best of 2017: Targeting cancer's 'Achilles heel'

Top Story Researchers have developed an effective new strategy for treating cancer, which has wiped out the disease to near completion in cellular cultures in the laboratory. The treatment works by controlling chromatin, a group of macromolecules — including DNA, RNA and proteins — that houses genetic information within cells and determines which genes get […]
