Scientists at the University of Oxford may have solved one of the biggest questions in modern physics, with a new paper unifying dark matter and dark energy into a single phenomenon: a fluid which possesses ‘negative mass’. If you were to push a negative mass, it would accelerate towards you. This astonishing new theory may also prove right a prediction that Einstein made 100 years ago.

Our current, widely recognised model of the Universe, called LambdaCDM, tells us nothing about what dark matter and dark energy are like physically. We only know about them because of the gravitational effects they have on other, observable matter.

This new model, published today in Astronomy and Astrophysics, by Dr Jamie Farnes from the Oxf...

A mouse study shows that a single workout can activate POMC neurons (shown in green in yellow) for up to 2 days. The activity of these neurons are important regulators of blood glucose levels and energy balance.

Study offers insight into brain’s potential role in fitness, diabetes therapy. A new study from UT Southwestern Medical Center shows neurons in mice that influence metabolism are active for up to two days after a single workout. The research offers new insight into the brain’s potential role in fitness and – in the longer term – may provide a target for developing therapies that improve metabolism.

“It doesn’t take much exercise to alter the activity of these neurons,” said Dr. Kevin Williams, a neuroscientist at UT Southwestern...

Graphene unlocks new potential for ‘smart textiles.’

An international team of scientists, led by Professor Monica Craciun from the University of Exeter Engineering department, has pioneered a new technique to create fully electronic fibres that can be incorporated into the production of everyday clothing. Currently, wearable electronics are achieved by essentially gluing devices to fabrics, which can mean they are too rigid and susceptible to malfunctioning.

The new research instead integrates the electronic devices into the fabric of the material, by coating electronic fibres with light-weight, durable components that will allow images to be shown directly on the fabric.

The research team believe that the discovery could revolutionise the creation of wearable elect...

NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft completed its 1.2 billion-mile (2 billion-kilometer) journey to arrive at the asteroid Bennu Monday. The spacecraft executed a maneuver that transitioned it from flying toward Bennu to operating around the asteroid.

Now, at about 11.8 miles (19 kilometers) from Bennu’s Sun-facing surface, OSIRIS-REx will begin a preliminary survey of the asteroid. The spacecraft will commence flyovers of Bennu’s north pole, equatorial region, and south pole, getting as close as nearly 4 miles (7 kilometers) above Bennu during each flyover.

The prima...
