We could be overlooking an entire population of asteroids that pose a threat to Earth on the very simple basis that they’re extremely hard to see. In the space shared by the orbit of Venus, hundreds of undiscovered asteroids could be orbiting the Sun, hidden from our view simply because of their position. Because they’re closer to the center of …

Scientists have created egg-like cells capable of fertilization using DNA from ordinary skin cells in what could be a major breakthrough for infertility research. Using a newly developed technique to remove excess chromosomes, a team led by clinical biologist Nuria Marti-Gutierrez of Oregon Health & Science University has created human eggs that can undergo successful fertilization and start to develop …

Our Universe was ‘pre-heated’ in its early moments, according to a new study from the International Centre of Radio Astronomy Research (ICRAR), challenging assumptions it emerged from an ultracold state. The discovery was made as astronomers hunted for an elusive signal from the Epoch of Reionization – the time when the first suns began to fire up about a billion …

A black hole analog could tell us a thing or two about an elusive radiation theoretically emitted by the real thing. Using a chain of atoms in single file to simulate the event horizon of a black hole, a team of physicists in 2022 observed the equivalent of what we call Hawking radiation – particles born from disturbances in the …

Sometime in the Middle Eocene epoch, nearly 50 million years ago, a large object hurtled through Earth’s atmosphere, crashing into the North Sea between what’s now Britain and northwestern Europe. The impact formed a crater 1 kilometer (about half a mile) deep and 3 kilometers wide. A plume of debris and water blasted skyward before falling back down, triggering a …

Imagine knowing in your 20s or 30s that you carry a gene that will cause your mind and body to slowly unravel. Huntington’s disease is inherited, relentless, and fatal, and there is no cure. Families live with the certainty of decline stretching across generations. Now, a new treatment is being widely reported as a breakthrough. Related: Breakthrough Gene Therapy Slows …

After years of research, scientists have discovered that rheumatoid arthritis is often preceded by a silent, symptomless stage. Catching the autoimmune disorder earlier could mean lessening the painful joint inflammation and damage, or even stopping its progression. Some people who develop rheumatoid arthritis (RA) are deemed at risk years before the appearance of joint inflammation (synovitis), due to the presence …

The asteroid belt is found orbiting between Mars and Jupiter and is a vast collection of rocks that is thought to be a planet that never formed. When our Solar System formed 4.6 billion years ago, the material in this region should have coalesced into a planet. However, Jupiter’s gravitational influence prevented this from happening, stirring up the region so …

Could tattoos be the secret weapon in the fight against skin cancer? It might sound incredibly unlikely at first, but new research suggests there’s more to tattoo ink than meets the eye, especially when it comes to melanoma risk. For years, people worried about the possible health dangers of tattoos. But new research suggests something surprising: people with multiple tattoos …

Research suggests a surprising link between blood type and stroke risk, with people carrying one specific group A blood type facing a higher likelihood of stroke before age 60. This finding, published in 2022, deepens our understanding of how our unique biological makeup can impact our health. You’ve probably heard of the A, B, AB, and O groups, which refer …
