Scientists Are Generating Oxygen from Simulated Moon Dust

Scientists Are Generating Oxygen from Simulated Moon Dust

European researchers are working on a system that can churn out breathable oxygen from simulated samples of moon dust.

“Being able to acquire oxygen from resources found on the Moon would obviously be hugely useful for future lunar settlers, both for breathing and in the local production of rocket fuel,” explained Beth Lomax, a chemist from the University of Glasgow, in an European Space...

Texas Judges Are Increasingly Denying Teens' Requests for Abortion Care

Texas Judges Are Increasingly Denying Teens' Requests for Abortion Care

In many places across America, it’s become harder for women to obtain an abortion. But a study out Thursday highlights an added challenge for teenage girls living in Texas and elsewhere: Judges who refuse to let them get an abortion without the involvement of their parents.

Legally, the Supreme Court has ruled since 1979 that no one can veto a minor’s decision to seek an abortion, including...

New Research Casts Doubt on Theory That Volcanoes Caused Dinosaur Extinction

New Research Casts Doubt on Theory That Volcanoes Caused Dinosaur Extinction

Scientists have new evidence in their quest to settle the longstanding debate about whether it was a gigantic meteorite or massive volcanic eruptions that triggered the mass extinction that wiped out the dinosaurs.

A curious thing about the Cretaceous-Paleogene (K-Pg) mass extinction is that two apocalyptic-scale events happened at roughly the same time. Some 66 million years ago, a large...

Scientists Built a Robot From 40 Pigeon Feathers and It Flies Beautifully

Scientists Built a Robot From 40 Pigeon Feathers and It Flies Beautifully

Scientists seeking to understand the mechanics of bird flight have constructed PigeonBot, a robot made from 40 pigeon feathers (and a few other components).

While airplanes maneuver by altering their wing elements, birds can morph the shape of their entire wings to dive, bank, and coast through the air, increasing both their efficiency and agility. This new study on pigeon wings has not only...

Cancer and Heart Disease Could Be Contagious Through Our Microbiomes, Scientists Argue

Cancer and Heart Disease Could Be Contagious Through Our Microbiomes, Scientists Argue

It’s a science lesson you probably learned in grade school: You can only catch certain illnesses, like the flu, from another person. But a new paper argues that many diseases seen as noncommunicable, like most cancers and heart disease, might be transmissible sometimes—thanks to the seemingly harmless microbes living in and on our bodies.

Every one of us is a walking zoo, filled to the brim...

Surprising Experiment Suggests Wolf Puppies Can Play Fetch

Surprising Experiment Suggests Wolf Puppies Can Play Fetch

Scientists in Sweden have shown that some wolf pups, like dogs, are capable of playing fetch with humans. It’s an unexpected result, one that suggests the ancestors of dogs were primed for domestication.

A new study published in iScience presents evidence showing that some wolf pups, with a bit of encouragement, will retrieve a tossed ball and return it to an unfamiliar human. In other words,...

Newly Sequenced Giant Squid Genome Raises as Many Questions as It Answers

Newly Sequenced Giant Squid Genome Raises as Many Questions as It Answers

One the most intriguing and mysterious creatures on the planet—the giant squid—has finally had its genome fully sequenced. But while the genome is helping to explain many of its distinguishing features, including its large size and big brain, we still have much to learn about this near-mythical beast.

“A genome is a first step for answering a lot of questions about the biology of these very...

Cat Parasite Makes Mice Less Fearful, but Not Just of Cats, Study Finds

Cat Parasite Makes Mice Less Fearful, but Not Just of Cats, Study Finds

The relationship between a notorious parasite spread by cats and the mice it infects might be more complex than we thought, according to new research out this week. It suggests that mice infected with Toxoplasma gondii aren’t just less afraid of cats—they’re more mellowed out in general.

Toxoplasma gondii, more plainly known as toxo, has earned plenty of attention for its creepy ways. The...

Free-Diving Neanderthals Gathered Tools From the Seafloor

Free-Diving Neanderthals Gathered Tools From the Seafloor

New evidence suggests Neanderthals gathered clam shells and volcanic rock from the bottom of the Mediterranean, which they fashioned into tools. The work is yet more evidence that Neanderthals often ventured into the water, and it adds to the body of research showing that they were nothing like the unintelligent, uncoordinated clods they’ve long been portrayed to be.

Researchers have...

A Man's Worm Infection Left Him with a 'Stony Hard' Testicle

A Man's Worm Infection Left Him with a 'Stony Hard' Testicle

There’s no good place for parasitic worms to wreak havoc in the human body, but doctors in India say their 80-year-old patient developed a particularly unfortunate case. The man’s worm infection left him with a massively swollen, calcified right testicle.

According to the paper, published earlier this month in BMJ Reports, the man had visited the doctor complaining of blood in his urine, a...

New Poll About Vaccines Is a Huge Bummer

New Poll About Vaccines Is a Huge Bummer

Many Americans have lost faith in the importance of vaccines over the past two decades, while more than half are unsure or wrongly believe that they can cause autism. At least, those are the somber conclusions of a new Gallup poll released Tuesday. Even worse is that parents of children under 18 have grown more skeptical of vaccines since 2015.

The poll, conducted by Gallup, interviewed just...

Has Hubble Detected Rogue Clumps of Dark Matter?

Has Hubble Detected Rogue Clumps of Dark Matter?

Scientists using the Hubble Space Telescope have discovered evidence of small clumps of dark matter warping the light from distant quasars.

Regular matter seems to form only a small part of the universe—much more of the matter seems to be “dark” stuff that influences regular matter via gravity but can’t be detected directly. The most widely accepted theory to explain dark matter suggests that...

Investigation Finds Widespread Rule-Breaking in Reporting of U.S. Clinical Trials

Investigation Finds Widespread Rule-Breaking in Reporting of U.S. Clinical Trials

Universities, drug companies, and government agencies are breaking the law and not turning in their science homework, according to a new report out Monday. It shows that many of these entities aren’t reporting the results of their research to the government’s database of clinical trials as legally mandated, while the government has done little to punish those who fail to comply.

The database,...

Fish Hooks Are Injuring a Shocking Number of Sharks

Fish Hooks Are Injuring a Shocking Number of Sharks

Observations of sharks swimming off the coast of Tahiti show the alarming degree to which fishing hooks remain attached to these marine predators.

A new paper published in Fisheries Research shows that 38 percent of tiger sharks living near French Polynesia, also known as Tahiti, have at least one fishing hook stuck in them or show signs of having been previously been snagged by a hook. The...

A New Study Claims to Disprove Dark Energy—but Cosmologists Aren't Convinced

It would be really, really exciting if a single observation could completely overturn astrophysicists’ current understanding of the universe. But that hasn’t happened yet, at least with regards to dark energy.

This week, a press release proclaimed that “new evidence shows that the key assumption made in the discovery of dark energy is in error,” garnering some attention from astronomers and...

Americans' Body Temperature Has Been Dropping Since the 19th Century, Study Finds

A new study has found evidence that the average blood temperature of people in the U.S. has lowered over the past century and a half—probably because we’re in better health.

The authors of the new study, published in the journal eLife, looked at the medical records of Americans, including Civil War veterans, from three periods of time: 1860–1940, 1971–1975, and 2007–2017. They found that...
