Some studies suggest the world is entering a sixth major extinction event. But now, in a rare piece of good news from that field, researchers from Australia, Canada and the US have rediscovered Wallace’s giant bee, an insect that hasn’t been seen in almost 40 years.

​Although concrete doesn't burn, it can "spall" when subjected to extreme heat – this means that surface layers of the material break off, potentially causing structures made of it to collapse. According to a new study, however, fibers obtained from discarded tires can help keep that from happening.

​When you think of lobsters and armor, the obvious connection would be their hard shells. An international team of scientists, however, is more interested in the flexible membrane on the underside of the crustaceans' tails. It has a unique structure, which could find uses in human technology.

Citroën’s latest solution to increasingly crowded urban centers and urban mobility is a boxy electric two-seater concept imagined as an alternative for buses, bikes and scooters, even for those without a license to drive.

A study is suggesting high iron levels in the brain may fundamentally trigger the progressive neurodegeneration associated with dementia and Alzheimer’s disease. A clinical trial is now underway exploring whether Alzheimer’s-related cognitive decline can be slowed by lowering brain iron levels.

How does one mix up the perfect cheese fondue? After studying how the ingredients interact with one another, scientists have found the dish is really a complex multiphase system caused by the flow behavior or rheology of the cheese, wine, and starches.

Project 001 was the insane Valkyrie. Project 002 was the Valkyrie AMR Pro. And now Aston Martin has confirmed that it's got a Project 003 in the pipeline as well - a mid-engined hypercar using a turbo gasoline/electric hybrid powertrain that's said to "offer more practical concessions to road use."

Radio waves are still the main way to communicate with spacecraft, but that aging technology could soon get an upgrade that will allow faster data downloads from space. NASA is currently preparing to test out an x-ray communication system on the International Space Station.

A team of genetic scientists at the Salk Institute have developed a new therapy using the CRISPR/Cas9 tool that takes a toxic protein out of the aging equation, with some promising results. ​

One of the surviving sledges from Sir Ernest Shackleton's 1907 failed attempt to reach the South Pole is going up for auction at the Bonhams Bonhams Travel and Exploration Sale in London..

A new brain-training app has been shown to improve attention and concentration after just one month of use. The smartphone game, developed by scientists from the University of Cambridge, is now commercially available, but not all experts are convinced of the app’s purported beneficial effects.

​When sewage sludge is processed at wastewater treatment plants, the leftover "biosolid" material is generally dried and set aside. While some of it ends up being used as fertilizer, much is often just stockpiled. Soon, however, it could find its way into eco-friendly fired-clay building bricks.
