Covid-19

Copper’s Virus-Killing Powers Were Known Even to the Ancients

The SARS-CoV-2 virus endures for days on plastic or metal but disintegrates soon after landing on copper surfaces. Here’s why

Breaking Down the Two Tests That Could Help Contain the COVID-19 Pandemic

One detects an active infection; another signals that the virus has already left the body. Both are critical for tracking the spread of disease

Danish physician Nadja Albertsen spent a year at Concordia Research Station in Antarctica.

Covid-19

Ten Tips From Scientists Who Have Spent Months in Isolation

Find a hobby, for starters, and don’t forget the mission, say scientists who have worked at remote research stations

Can you become immune to SARS-CoV-2?

Covid-19

What Scientists Know About Immunity to the Novel Coronavirus

Though COVID-19 likely makes recovered patients immune, experts aren’t sure how long protection lasts

Covid-19

How a Few Sick Tobacco Plants Led Scientists to Unravel the Truth About Viruses

With the COVID-19 coronavirus causing a global pandemic, a look back at the scientists who figured out viruses and their relationship to disease

Warmer weather can bring blooms. But don't expect it to resolve the COVID-19 pandemic on its own.

Covid-19

Why Warmer Weather Probably Won’t Stop COVID-19

Yes, most infectious diseases are seasonal. But waiting for COVID-19 to wane on its own is a bad idea

Washing your hands doesn't just lift germs off your skin. It can destroy some of them, too—including the virus behind COVID-19.

Why Is Washing Your Hands So Important, Anyway?

A dive into the science behind why hand-washing and alcohol-based hand sanitizer work so well

Ten Trends That Will Shape Science in the Decade Ahead

Medicine gets trippy, solar takes over, and humanity—finally, maybe—goes back to the moon

Allene Goodenough (right) and Helyn James of the Young Women's Christian Association mop up a spot on the sidewalk where someone expectorated by an anti-spitting sign during a public health campaign in Syracuse, New York, in 1900.

Women Who Shaped History

When a Women-Led Campaign Made It Illegal to Spit in Public in New York City

While the efficacy of the spitting policy in preventing disease transmission was questionable, it helped usher in an era of modern public health laws

By detecting the genetic traces of cancer cells in a patient's blood, medical scientists could open the door to easier diagnosis and more effective treatments.

How Simple Blood Tests Could Revolutionize Cancer Treatment

The latest DNA science can match tumor types to new treatments, and soon, a blood test might be able to detect early signs of cancer

Artists Who Paint With Their Feet Have Unique Brain Patterns

Neuroscientists determined that certain “sensory maps” in the brain become more refined when people use their feet like hands

Axolotls can regrow lost limbs, again and again, making them appealing to scientists who want to understand regeneration.

Some Salamanders Can Regrow Lost Body Parts. Could Humans One Day Do the Same?

In recent decades, the idea of human regeneration has evolved from an ‘if’ to a ‘when’

Each year, people need to get a new flu shot to protect against the latest version of the influenza virus, which rapidly mutates. A universal flu vaccine could protect people for life.

As the World Faces One of the Worst Flu Outbreaks in Decades, Scientists Eye a Universal Vaccine

A universal flu vaccine would eliminate the need for seasonal shots and defend against the next major outbreak

Scientists Assemble Frog Stem Cells Into First ‘Living Machines’

The so-called ‘xenobots’ could replace traditional metal or plastic robots without polluting the planet, but they raise ethical questions

These are ten of the biggest strides made by scientists in the last ten years.

The Top Ten Scientific Discoveries of the Decade

Breakthroughs include measuring the true nature of the universe, finding new species of human ancestors, and unlocking new ways to fight disease

Microneedle patches, like this one that measures about a centimeter across, could be used to deliver nanoparticles when pressed to the skin for two minutes.

This Spiky Patch Could Invisibly Record Vaccination History Under Skin

But the technology raise several ethical concerns that could stymie its progress

Several Homo erectus skulls were recently identified as the youngest known fossils of the species, some 108,000 to 117,000 years old. These fossil replicas are housed at the University of Iowa.

Fossils From Some of the Last Homo Erectus Hint at the End of the Long-Lived Species

Homo erectus, one of the first species of the Homo genus, survived for longer than any other close human ancestor

A 5,700-year-old piece of birch tar, chewed as gum, contains the genome, mouth microbes, and even dietary information about its former chewer.

Human Genome Recovered From 5,700-Year-Old Chewing Gum

The piece of Birch tar, found in Denmark, also contained the mouth microbes of its ancient chewer, as well as remnants of food to reveal what she ate

Miniature Brains Recently Sent Out Brain Waves for the First Time

The brain organoids, about the size of a pea, can be used to better understand neurological diseases

A picture of Friedrich Miescher hangs behind a test tube with isolated nucleic acid from salmon sperm from the original holdings in the museum of the University of Tübingen.
