Every year, thousands of donated organs go to waste because they cannot be matched with recipients in the brief window of time in which they are still viable.
Extending the shelf-life of organs could help alleviate this problem, potentially cutting into waiting lists for organs where many patients languish for years. Chilling organs at extremely low temperatures and then reheating them when they are needed is one curren ...read more
Haematite tubes from the hydrothermal vent deposits are said to be the oldest microfossils and evidence for life on Earth. (Credit: Matthew Dodd)
Four billion years ago, as a faint young sun beat down on the newly-formed Earth, a cluster of creatures—each less than half the width of a human hair—were already thriving around volcanic vents.
In a study published Wednesday in Nature, researchers say they’ve found the microfossil remnants of organisms that, if confirmed, lived at ...read more

Calorie-free, artificial sweeteners aren’t metabolized in the body—they go in, and they come out unscathed.
With that in mind, take a moment to metabolize the title of a new study: “Sweetened Swimming Pools and Hot Tubs.”
Indeed, in a study published Wednesday in Environmental Science & Technology Letters, researchers describe a new test that measures levels of acesulfame-K, a widely consumed artificial swee ...read more

In the land down under, feral cats slaughter an estimated 75 million native animals each day. That threat to biodiversity prompted the Australian government to declare it would kill 2 million feral cats over five years starting in 2015. As part of that campaign, officials plan to enlist a drone air force ca ...read more

Firing lasers at fossils continues to be a winning strategy for paleontologists.
The new technique brings hidden details in fossils to the forefront, including remnants of soft tissue invisible to the naked eye. And a team of researchers from China is using the laser-assisted images to help piece together the evolutionary process that turned dinosaurs into the birds we know today.
In a paper published Tues ...read more
