Interstellar isotopes found in Antarctica were forged from supernovae

In the pure white snow of Antarctica, scientists have found rare isotopes that don’t occur naturally on Earth. The isotope, known as iron-60, is usually forged in the crucible of supernova explosions, and the researchers believe it fell to Ea… Continue reading Interstellar isotopes found in Antarctica were forged from supernovae

Food scientists cook up low-fat better butter made of mostly water

Often imitated but rarely matched, butter is one ingredient that it’s important to get right. People are picky about the consistency and creaminess of their butter, and healthier alternatives have trouble getting that right. Now, food scienti… Continue reading Food scientists cook up low-fat better butter made of mostly water

Atomic experiment to detect dark energy fails to feel the force

The universe is generally believed to be expanding at an accelerating rate, thanks to a mysterious force dubbed dark energy. But how exactly does this force work? Researchers in the UK have conducted an experiment to test a hypothesis that th… Continue reading Atomic experiment to detect dark energy fails to feel the force

FDA approves clinical trial of cold plasma "scalpel" for cancer treatment

Cancer is a crafty foe, not least because traces often remain after surgery and can trigger a relapse later on. Now a new technology to fight those dangerous leftovers – a cold atmospheric plasma system – has been approved for human clinical … Continue reading FDA approves clinical trial of cold plasma "scalpel" for cancer treatment

Eight new repeating radio signals detected from deep space

Fast radio bursts (FRBs) are one of the most intriguing mysteries of modern astronomy. Picked up from all corners of the cosmos, these perplexing radio signals usually only last milliseconds before fading forever, but some particularly strang… Continue reading Eight new repeating radio signals detected from deep space

Understanding E. coli's stealthy secret could help render it harmless

Pathogenic E. coli usually waits until it gets to the large intestine before taking hold, but ...

The human immune system is pretty good at wiping out dangerous invaders – which is why some of these invaders have developed ways to avoid detection until they’re ready. Now, researchers from the University of Virginia (UVA) may have found a way to prevent infections by making sure that these bugs are never ready. The team has uncovered how pathogenic E. coli senses its environment to stay stealthy until it reaches the right spot to kickstart an infection.

Ancient tools suggest humans spread across Eurasia earlier than previously thought

The story of human history is patchy at best, but now another patch may have been filled in. Archaeologists have found ancient tools at a dig site in Mongolia, indicating that humans were on the scene about 45,000 years ago, which is much ear… Continue reading Ancient tools suggest humans spread across Eurasia earlier than previously thought

Gravitational waves point to a black hole swallowing a neutron star

Astronomers have detected a gravitational wave signal that appears to have been caused by a black hole swallowing a neutron star. Aside from being an incredible cosmic cataclysm to witness, this detection is important for another reason: it m… Continue reading Gravitational waves point to a black hole swallowing a neutron star

Melting icebergs could play significant role in slowing down warming

The melting of Antarctic ice sheets is one of the most visceral consequences of climate change, but the full extent of their impact on the cycle remains mostly unknown. Now, researchers from the US and South Korea have run climate simulations… Continue reading Melting icebergs could play significant role in slowing down warming

Newly discovered sensory "organ" may play a painful role

You may think that we’ve got a pretty good handle on which organs there are in the body by now, but it turns out that the final count is surprisingly contentious. Researchers at Karolinska Institutet in Sweden claim to have discovered a new s… Continue reading Newly discovered sensory "organ" may play a painful role
