First, it was face masks. Now it's hand sanitizer. Items that weren't valuable just a couple months ago are now coveted, hoarded, and flying off store shelves.

Something in the Universe is creating more mass than we can detect directly. We know it's there because of its gravitational effect on the stuff we can detect; but we don't know what it is, or how it got here.

Ancient fern-like creatures known as rangeomorphs might not have been as lonely as we once imagined. Filaments discovered in half-a-billion year old rocks in Newfoundland, Canada, suggest clusters of these early animals could have connected up thro

NASA on Thursday announced the name of its next Mars rover: Perseverance.

The race is on to identify an effective vaccine for the COVID-19 virus. Once discovered, the next challenge will be manufacturing and distributing it around the world.

The official verdict is in. As the red supergiant Betelgeuse once again returns to normal brightness levels, astronomers have taken the star's temperature to identify the cause of its recent dimming.

Around 4.5 billion years ago, something the size of Mars collided with a newly formed Earth, to colossal effect. This object is not only thought to have fused with Earth and primed it for life, it also broke off a large chunk that went on to become

It's lonely out there in deep space. Especially when a spacecraft has travelled so far into the vast emptiness, interstellar space is now all it can truly call home.

Astronomers have used an algorithm based on the growth patterns of slime mould to map something that's basically impossible to see: the cosmic web of gas and dark matter underpinning the very structure of the Universe.

A second patient has been cured of HIV after undergoing stem cell transplant treatment, doctors said Tuesday, after finding no trace of infection 30 months after he stopped traditional treatment.

Life during a global pandemic takes on a surreal quality. The ubiquitous presence of social media and a constant fire hose of coronavirus news can make it particularly hard if you're already feeling anxious.

To date, we humans have positively identified over 4,000 exoplanets in the Milky Way galaxy. And, to date, all of those exoplanets have something in common: they're located in the relatively flat disc of the galactic plane, the thin disc.

Diabetes has afflicted humanity for thousands of years, but despite it being an old burden, we're still making major discoveries about how the illness actually manifests, as new research shows.

The shape of the earliest building blocks of life dating back as far as 3.5 billion years ago may have been identified, due to a new effort to envisage the molecular arrangements of the planet's very first proteins.

Anyone experiencing a sudden loss of smell could be a "hidden carrier" of the coronavirus, even if they have no other symptoms, according to evidence compiled by leading rhinologists in the UK.

In the heart of a galaxy cluster 200 million light-years away, astronomers have failed to detect hypothetical particles called axions.

Australian researchers are fast-tracking large-scale human testing to see if a vaccine used for decades to prevent tuberculosis can protect health workers from COVID-19, they announced Friday.

In 2015, astronomers found something weird. It was a white dwarf star, 570 light-years from Earth, with a peculiar dimming pattern. It dimmed several times to varying depths, each depth repeating on a 4.5 to 5-hour timeframe; and its atmosphere was

Despite humanity's current struggle against the novel coronavirus, and despite it taking up most of our attention, other threats still exist. The very real threat of a possible asteroid strike on Earth in the future is taking a backseat for now, bu
