Seattle-based USNC-Tech has developed a concept for a safer and more reliable Nuclear Thermal Propulsion system that could help realize the goal reducing Earth-Mars travel time to just three months.

Images returned by NASA's OSIRIS-REx asteroid explorer have confirmed that the spacecraft's sample collector head is slowly leaking some of the material it gathered from the surface of the asteroid Bennu, but it's not all bad news.

When someone has suffered a stroke, it's imperative that they receive medical attention as soon as possible. And while current diagnostic procedures take some time, an experimental smartphone app could deliver results much quicker.

We are seeing some exciting research advances that could help reveal Parkinson's in its ealy stages. Scientists have now produced another by demonstrating how a skin biopsy can be used to identify the disease with a high degree of accuracy.

Researchers have developed a way to treat male infertility by delivering nanoparticles loaded with proteins directly into the testes. In tests in mice, previously infertile animals were soon able to father pups at a similar rate as unaffected mice.

A new study has identified 1,004 stars from which aliens could detect signs of life in Earth’s atmosphere by watching as our planet passes across the disk of the Sun. The study could help provide targets for groups searching for alien civilizations.

Scientists in Japan have produced a plastic with the highest heat resistance ever reported, and done so by using natural materials as the building blocks, paving the way toward greener production for the omnipresent material.

Ironclad beetles can survive being run over by a car and scientists have now unlocked some of the secrets behind this incredible toughness, which they say paves the way for a new breed of materials that bear similar characteristics.

On Tuesday this week, NASA’s OSIRIS-REx spacecraft briefly touched down on the surface of asteroid Bennu to snatch a sample of the ancient pristine rock, and took off again. And now NASA has released images and video from the robot’s perspective.

A new study claims to explain the association between gum disease and diabetes, cardiovascular disease and even Alzheimer’s. The research demonstrates how periodontitis can initiate a systemic immune response that spreads throughout the entire body.

Given that not everyone has the same tolerance for hot chilis, it would be good if there were a simple, portable means of objectively assessing how hot they are. Well, scientists have developed just such a gadget – and it plugs into a smartphone.

Typically, motion capture systems are confined to one studio containing multiple cameras, and they require subjects to wear sensor-equipped body suits. A new setup, however, is based around a single chest-mounted camera.
