The spray uses snippets of DNA to gum up virus replication.
There’s an extremely good chance that there is, or at least was, life on Mars. But is it native to Mars, or did it originate from Earth?
Life became a possibility in the Universe as soon as the raw ingredients were present. But living, inhabited worlds required a bit more.
In movies and TV shows, aliens look like pointy-eared humans. Is this realistic? If evolution is predictable, then it very well might be.
We may have discovered alien life already but rejected the evidence too quickly because it seemed false at first glance.
Sweet, bitter, salty, sour. These are the four basic tastes we were taught in grade school. But there is a fifth: umami. And it’s everywhere.
Is blood the key to anti-aging, or just another lucrative biotech opportunity?
There is currently no easy way to treat high Lp(a). A single shot could change that.
Anesthesia causes animals and humans to lose consciousness. A study found it has a similar effect on Venus flytraps.
Capsaicin is already used to treat nerve pain. Early research hints it could do more.
“I hope we take a mindset where we are willing to look for weird life in weird places.”
Once activated, the CRISPR-Cas12a2 system goes on a rampage, chopping up DNA and RNA indiscriminately, causing cell death.
The central equation of quantum mechanics, the Schrödinger equation, is different from the equations found in classical physics.
Reframing life in terms of death reveals some of the biggest philosophical problems with how we think about living systems.
The whole isn’t greater than the sum of its parts; that’s a flaw in our thinking. Non-reductionism requires magic, not merely science.
Probably not. Even though we’re still investigating the origin of life, the evidence suggests that cells came much later.
Scientists are finding tumor signals in spit that could be key to developing diagnostic tests for various types of cancer.
In physics, we reduce things to their elementary, fundamental components, and build emergent things out of them. That’s not the full story.
Amplifying the energy within a laser, over and over, won’t get you an infinite amount of energy. There’s a fundamental limit due to physics.
Venus has far more carbon dioxide in its atmosphere than Earth, which turned our sister planet into an inferno. But how did it get there?
From the explosions themselves to their unique and vibrant colors, the fireworks displays we adore require quantum physics.
New research shows that the transition from general to specific memories involves the maturation of inhibitory neurons in the hippocampus.
More work is needed before declaring the technique a fountain of youth.
A medical entomologist points to metabolism, body odor, and mindset.
The scientists are headed “straight to the FDA” to begin human trials.
Biological age is a better health indicator than the number of years you’ve lived, but it’s tricky to measure.
If the laws of physics are symmetrical as we think they are, then the Big Bang should have created matter and antimatter in the same amount.
In a study involving mice, scientists used two different techniques — one optogenetic and one pharmacologic — to recover “lost” memories.
HIV mutates rapidly, which has made the development of a vaccine an enormous challenge for decades. Finally, we might have one.
