One of the greatest mysteries in astrophysics these days is a tiny subatomic particle called a neutrino, so small that it passes through matter – the atmosphere, our bodies, the very Earth – without detection.
Physicists around the world have…

Discovery points to origin of mysterious ultraviolet radiation
Billions of lightyears away, gigantic clouds of hydrogen gas produce a special kind of radiation, a type of ultraviolet light known as Lyman-alpha emissions.
The enormous clouds emitting the light are Lyman-alpha blobs (LABs). LABs are several…

Seismic imaging technology could deliver finely detailed images of the human brain
Scientists have developed a new computational technique that could lead to fast, finely detailed brain imaging with a compact device that uses only sound waves.
The Imperial College London and UCL researchers say their proof-of-concept study,…

Scientists shed light on mystery of dark matter
Scientists have identified a sub-atomic particle that could have formed the “dark matter” in the Universe during the Big Bang.
Up to 80% of the Universe could be dark matter, but despite many decades of study, its physical origin has remained…

Ocean changes almost starved life of oxygen 800 million years ago
Chemical changes in the oceans more than 800 million years ago almost destroyed the oxygen-rich atmosphere that paved the way for complex life on Earth, new research suggests.
Then, as now, the planet had an “oxidizing” atmosphere, driven by…

Hydrogen energy at the root of life
Since the discovery of submarine hydrothermal vents around 40 years ago, these natural chemical reactors have been a focus for evolutionary researchers searching for the origin of life.
The vents emit hot water containing minerals, including…

Scientists one step closer to understanding the mystery of matter in the universe
Scientists at the University of Sussex have measured a property of the neutron – a fundamental particle in the universe – more precisely than ever before.
Their research is part of an investigation into why there is matter left over in the…

Our digital afterlife
Social media pages and accounts often turn into memorials when someone dies, giving people a chance to still feel connected to those they’ve lost.
But after we’re gone, who owns the information on our pages? Who can access them?
