Does My Smartwatch's Sleep Tracker Actually Do Anything?

Does My Smartwatch's Sleep Tracker Actually Do Anything?

For most of my adult life, I didn’t really think about sleep: It was just an activity that my body required, for about six to eight hours a night, in order to not feel like garbage the next day. Rarely did I pause to consider the quality of my rest or whether my sleep patterns were “normal.” That is, until I was gifted a Fitbit Charge 3.

Now, just about every morning, I open my phone’s...

E-Cigarette Vapor Linked to Lung Cancer in Mice

E-Cigarette Vapor Linked to Lung Cancer in Mice

A new study out Monday is yet more evidence that vaping isn’t the completely safe alternative to smoking it was once thought to be. The researchers claim to have found evidence, in mice, that e-cigarette vapor is capable of causing certain kinds of cancer. But there’s still a long way to go before we can know if the same is true in people and how large of a cancer risk it could pose.

There’ve...

State Fair Hot Tubs Probably Spread Deadly Legionnaires' Disease Outbreak in North Carolina

State Fair Hot Tubs Probably Spread Deadly Legionnaires' Disease Outbreak in North Carolina

State fairs are a mixed bag in the best of times. But for a hundred or so people who attended the North Carolina Mountain State Fair this past September, it was a nightmare. State health officials have traced an outbreak of Legionnaires’ disease to the fair, with the most likely source of infection being contaminated hot tubs.

The fair ran from September 6 to 15. Since then, according to the...

Here's More Evidence That Earth Got Hit by Something Huge 12,800 Years Ago

Here's More Evidence That Earth Got Hit by Something Huge 12,800 Years Ago

New evidence from South Africa is adding further credence to the idea that a large asteroid or comet struck Earth during the Pleistocene—an event that possibly triggered the extinction of many large animals while also disrupting human populations at a global scale.

Along with locations in North and South America, Greenland, Western Europe, and the Middle East, we can now add southern Africa to...

Aspirin, Strangely Enough, Might Protect Our Lungs From Air Pollution

Aspirin, Strangely Enough, Might Protect Our Lungs From Air Pollution

A dose of aspirin can do more than just soothe your headache, a new study suggests—it might also protect your lungs from air pollution.

Air pollution harms our bodies in all sorts of ways , both short-term and long-term. One of these ways is through irritating and inflaming lung cells. So it makes sense that aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) could have a...

Mysterious Chilean Fireballs Weren't Meteorites—So What Were They?

Mysterious Chilean Fireballs Weren't Meteorites—So What Were They?

Flashes lit up the sky over Chile last week, some even causing fires on the ground—but a new report has found that the origin of these fireballs is a mystery.

The Chilean National Geology and Mining Service released a report last weekend, the result of analysis from visiting seven of the charred sites where the objects touched down in the town of Dalcahue. These sites contained no evidence of...

National Academy of Sciences Removes Video Suggesting Gene Editing Could Be Used to Make Designer Babies

National Academy of Sciences Removes Video Suggesting Gene Editing Could Be Used to Make Designer Babies

The partially U.S. government-funded National Academy of Sciences removed a webpage with a video describing gene editing in ways that conflict with the organization’s own ethical guidelines.

The NAS has updated the webpage where the video once resided with a note saying, “We are concerned that the content, including a video, left the misimpression that the use of genome editing for the...

Prospective Fathers Should Avoid Binge Drinking, Study Finds

Prospective Fathers Should Avoid Binge Drinking, Study Finds

Prospective parents—but especially dads—might be wise to avoid too much alcohol, according to a new study out this week. It suggests that women and men who binge drink in the months before conception are more likely to have children with congenital heart defects, with the father’s alcohol consumption surprisingly having a greater impact on the future child’s heart health.

The study, published...

Rodents With Part-Human Brains Pose a New Challenge for Bioethics

Rodents With Part-Human Brains Pose a New Challenge for Bioethics

Rapid progress in research involving miniature human brains grown in a dish has led to a host of ethical concerns, particularly when these human brain cells are transplanted into nonhuman animals. A new paper evaluates the potential risks of creating “humanized” animals, while providing a pathway for scientists to move forward in this important area.

Neuroscientist Isaac Chen from the Perelman...

A New Spray-On Gel Could Help Stop Wildfires Before They Start, Researchers Say

A New Spray-On Gel Could Help Stop Wildfires Before They Start, Researchers Say

Every year around 10 million acres of the U.S. is seared by wildfires. The country spends more than $2 billion trying to fight them—a total that doesn’t even include the cost of lost property. Fighting wildfires is still mostly a reactive effort, something that happens after the fires have already ignited. But researchers at Stanford University have created a gel-like fluid that can make it...

The Federal Attack on Science Has Reached a 'Crisis Point,' Damning Report Shows

Presidents have taken steps to breakdown the integrity of the science federal agencies produce, according to a new report. Under President Donald Trump, however, the situation has gotten a whole lot worse, reaching what the report calls “a crisis point.”

New York University’s Brennan Center for Justice published the 72-page report Thursday, offering proposals for how the government can better...

Scientists Uncover New Organic Molecules Coming Off Saturn's Moon Enceladus

Scientists Uncover New Organic Molecules Coming Off Saturn's Moon Enceladus

Scientists have discovered nitrogen- and oxygen- containing organic molecules in ice grains blown out by Saturn’s moon Enceladus, according to a new study.

Gas giants Saturn and Jupiter are orbited by some moons that almost seem more like planets themselves. One such moon is Saturn’s Enceladus, an icy orb thought to contain a very deep subsurface water ocean beneath a thick icy crust. Finding...

Judge Rules That Supervised Injection Site Planned in Philly Is Legal

On Wednesday, a federal judge struck down the U.S. government’s attempt to stop the development of the country’s first supervised injection site in Philadelphia—a move heralded by many public health experts worried about the opioid and drug overdose crisis.

Supervised, or safe, injection sites are public spaces where people are given the opportunity to use illicit drugs safely without the...

Study: Nuclear War Between India and Pakistan Would Trigger Global Starvation

Study: Nuclear War Between India and Pakistan Would Trigger Global Starvation

In addition to killing as many as 125 million people, a nuclear exchange between India and Pakistan would unleash mass starvation around the world due to the ensuing climate impacts, according to a disturbing new study.

As if we need to be reminded of the horrors of nuclear war, new research published today in Science Advances presents evidence showing that a nuclear exchange between two minor...

The Sad Truth About Floppy-Eared Bunnies

Floppy-eared rabbits, also known as lop rabbits, are more susceptible to serious ear and tooth disorders than upright-eared domesticated rabbits, according to new research. The findings are raising important concerns about the appropriateness of breeding lop rabbits, adorable as they are.

Floppy-eared rabbits don’t exist in nature. Rather, they are the products of artificial selection, in...

Would Finding Life on Mars Really Change Anything?

Would Finding Life on Mars Really Change Anything?

In a recent interview with the Telegraph, NASA chief scientist Jim Green said it’s possible we’ll soon find evidence of life on Mars but that “we’re not prepared for the results.” Green said the discovery would be as world-shaking as the revelation that the solar system doesn’t revolve around Earth. But while finding our first aliens would no doubt be amazing, it’s not a given that it would...

Peter Thiel's VC Fund to Host Conference for Ideological 'Heretics,' Maybe Summon a Ghost or Two

“Ideological outcasts” who have been “banned from other conferences”—surely the country’s most beleaguered minority—can soon find a home with other like-minded individuals at “Hereticon,” a three-day conference being planned by the Founders Fund venture capital firm.

That’s the same Founders Fund run by billionaire Peter Thiel, a kindred soul in the world of supposed ideological witch-hunt...
