People caught and died from plague long before it caused major epidemics like the Black Death in the middle ages. Could what scientists call cultural resistance be what kept the disease under control?
This artist’s impression shows a view of the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to the solar system.
Beyond the outer edge of the Solar System, mysterious, unknown worlds await by the thousands. Astronomers can now finally find them and explore them - but will we find another Earth?
Keep those stinkers away!
Sweaty feet and certain cheeses have something in common that makes them reek – can you guess what it is?
If only it were as easy as pushing a button.
Many sites offer the ability to 'opt out' of targeted advertisements, but doing so isn't easy. Simplifying and standardizing opt-outs would help improve privacy on the web.
Delivering DNA to immune cells is the trickiest part of developing new gene-based therapies.
Researchers are trying to boost the power of our immune system by genetically altering our white blood cells and transforming them into super-soldiers to fight cancer.
A rabid dog’s bite can make a person seem to have animal characteristics.
Fear of a disease that seemed to turn people into beasts might have inspired belief in supernatural beings that live on in today's creepy Halloween costumes.
The talamanca hummingbird, or admirable hummingbird, is found in Costa Rica and Panama.
How many genes do you really need? Are there any that we can lose? Researchers are now identifying species that have streamlined their genome to adapt to a particular lifestyle.

The first internet communication was underwhelming, thanks to a computer crash. But a lot has happened since then – including key decisions that helped build the internet of today.
What can your vacation pix tell scientists?
To untangle the relationship between climate change, fall foliage and national park visitors, researchers are asking tourists to check their old photo albums for snapshots that could hold valuable data.
Sulfur pollution causes respiratory health problems.

Sulfur contaminates gasoline and coal, and when these fuels are burned, sulfur dioxide is emitted, causing pollution and respiratory issues. Now there may be a new, cheaper way to remove it.
The muck that’s been accumulating at the bottom of this lake for 20,000 years is like a climate time capsule.
Christopher R. Moore
Why did Earth's climate rapidly cool 12,800 years ago? Evidence is mounting that a comet or asteroid collision is to blame, with new support coming from the bottom of a South Carolina lake.
What’s happening with the trees that stay green?
Many deciduous trees put on a dazzling fall foliage display. But coniferous evergreens hold on to their needles and stay green. A biologist breaks down these different survival strategies.
What makes a brain tick is very different from how computers operate.
Brain functions integrate and compress multiple components of an experience, including sight and smell – which simply can't be handled in the way computers sense, process and store data.
Red quantum dots glow inside a rat brain cell.
Nanoscale Advances, 2019, 1, 3424 - 3442
These tiny nanoparticles might provide a new way to see what's happening in the brain and even deliver treatments to specific cells – if researchers figure out how to use them safely and effectively.
