Polio can be circulating through a community long before anyone is paralyzed. Monitoring sewage for the virus lets public health officials short-circuit this 'silent transmission.'
How well will artificial intelligence balance the human concept of fairness?
Artificial intelligence poses opportunities as well as dangers; understanding them – and regulating carefully – will help avoid harm to individuals and society as a whole.
An e-ballot is less secure than one on paper.
The stability and integrity of democratic society are too important to be relegated to inherently flawed computer systems that are vulnerable to malfunctions and malicious attacks.

The United States already has a space agency: NASA. So why do we need a Space Force, and what would it do? Could a Space Force strain diplomatic relationships, reigniting the race to militarize space?
What if you could make a microchip at home?
Cybersecurity efforts could take a lead from open-source software, creating hardware whose designs are open for all to see and examine.

Only a small fraction of the data from archaeological fieldwork is made accessible to the public or preserved for future research.
Evolution is not just for living beings.
Artificial intelligence research owes a lot to biology and chemistry.

Smooth surfaces often provide nooks and crannies for bacteria to hold onto and create a colony. New research with nanoparticles is revealing the secrets of surfaces that prevent bacterial attachment.
Hormone signals help ready worker mole-rats to treat pups as their own.
Worker naked mole-rats take care of their colony's young even though they aren't the pups' actual parents. New research suggests the queen gets them ready via hormones in her poop.
Visiting an extreme haunted house can be delightfully terrifying.

Visiting a haunted house or watching a horror movie can be terrifying and enjoyable at the same time. A sociologist explains the psychological benefits of being safely scared.
The bubbly cloud, called Puppis A, is an irregular shock wave, generated by a supernova that would have been witnessed on Earth 3,700 years ago.
A massive star, with a radius 500 times that of our sun, exploded. But the supernova fizzled – it was weak and dim. Figuring out what went wrong led to insights about how rare binary star systems form.

Yes, giant mosquitoes are a thing. They're specialized to wait out the dry times only to emerge from their eggs when high water provides the perfect larval environment.
Many farmers cultivating organic crops believe that genetically modified crops pose threats to human health.
Is gene editing compatible with organic farming? A scholar explains the differences between old genetic engineering and CRISPR methods, and why the latter is similar to tradition plant breeding.
Every surface of our body – inside and out – is covered in microorganisms: bacteria, viruses, fungi and many other microscopic life forms.
Just because you don't have the flu doesn't mean that your aren't teeming with viruses inside and out. But what are all these viruses doing, if they aren't making you sick?
When many people hear the word cloning, they imagine armies of human clones created for nefarious purposes.
A scientist explains how researchers use cloning in the lab and what is the difference between cloning a gene versus cloning an entire organism.
Only 3 percent of these prizes have gone to women since 1901.
Progress has been made toward gender parity in science fields. But explicit and implicit barriers still hold women back from advancing in the same numbers as men to the upper reaches of STEM academia.

A legal loophole could grant computer systems many legal rights people have – threatening human rights and dignity and setting up some real legal and moral problems.
Scientists are now using evolution to create designer proteins for therapies and industrial processes.

Nature doesn't always make the things we need so three Nobel Prize winners figured out how to fast-track evolution in the lab to create medicines, biofuels and industrial chemicals for modern life.
Research is finding better ways to make batteries both big and small.
Is it too much to dream of batteries that are part of the structure of an item, helping to shape the form of a smartphone, car or building while also powering its functions?
Even 17 years beyond 2001, spacesuits are bulkier than this.

People are still wrestling with what artificial intelligence could and should do, half a century after the debut of the Kubrick-Clarke classic.
The 2018 Nobel Prize for physics recognized discoveries that can make more powerful lasers.
The Nobel Prize for physics was awarded to three scientists for the inventions of optical tweezers – in which two laser beams can hold a tiny object – and a method for creating powerful lasers.
When cyclists take over road lanes, self-driving cars will operate less efficiently.
Autonomous cars and people-centered communities are mutually exclusive, writes a cyclist and transportation scholar.
Man and machine.
Artificial intelligence and data analytics are transforming the practice of law.
Does your body give away if you’re lying or not?

It would be great to know for sure when someone is lying and when someone is telling the truth. But no technology that purports to do so is foolproof.
