When in possession of a priceless dinosaur skeleton, it’s always a good idea to fire a super-charged photon beam at it.
That’s Thomas G. Kaye’s philosophy: if you can fossilize it, you can fire a laser at it. Kaye, of the Foundation of Scientific Advancement, Sierra Vista, developed a laser-scanning technique that reveals stunning new details buried within dinosaur fossils — so meta. Now he’s traveling the world placing new specimens in his crosshairs.
Kaye is joined by Mike Pittman, who’s already infamous at Discover for spotting fossils while taking a whiz in the Gobi Desert. Together, they’re trekking around the world armed with nothing more than their portable laser and an inquisitive eye. Read More
In the decrepit ruins of a Cold War-era Kazakhstani hangar, buried beneath decades of detritus, there’s a spaceship that was once the last hope of the Soviet space empire.
And you’d be forgiven for confusing the Buran shuttles (Russian for “snowstorm”) with say, America’s iconic Space Shuttle Enterprise, which is proudly displayed in a Manhattan museum. Their shapes, sizes and technology are almost identical, apart from the sickle and hammer. Read More
Most women experience some type of morning sickness during pregnancy, but some women develop a far more serious condition.
Hyperemesis gravidarum (HG), which causes severe nausea and vomiting during pregnancy, affects as many as 3 percent of pregnancies, leading to over 167,000 emergency department visits each year in the U.S.
And yet, the disease is neither well-understood nor well-known, even with the flurry of headlines when it was announced that the Duchess of Cambridge during her pregnancies suffered from the condition. Read More
Advances in reproductive technology may radically change the options we have for starting a family. We’re not too far from fundamentally redefining what it means to start a family.
Do you want to have children, but don’t have a partner? Do you want children with your partner, but it’s a same-sex relationship? Or perhaps you’re a woman who wants children without the burden of a 9-month pregnancy. You might opt for ectogenesis, or moving gestation to an artificial womb.
Here’s a glimpse of this brave new world of baby-making. Read More
Time. Astronomers, philosophers, physicists, anthropologists, politicians, geographers, and theologians have all pondered the nature and meaning of time. Is it linear or cyclical? Is it reversible? (Put another way, can we go back in time?) Is time absolute and measurable, as it seemed to be to Isaac Newton and Galileo Galilei, or is it relative, as Albert Einstein theorized? Cynically, is it “what keeps everything from happening at once,” as science fiction author Ray Cummings wrote so memorably in 1923? Is time a cultural construct? Or is it a corollary to the second law of thermodynamics, under which disorder always increases? Why does time seem to go so much faster the older we get? Read More
Every year, the National Institutes of Health and the Centers for Disease Control allocate more than $35 billion to researchers to study diseases, treatments and public health. But there’s one public health concern that hasn’t received funding in nearly two decades: firearm regulations.
Firearms accounted for more than 30,000 deaths in 2014 — about the same number as died from motor vehicle accidents. With vanishingly few studies to investigate firearm deaths, however, researchers are unable to recommend the best course of action for public health officials to take.
In 1996, Congress passed legislation that specifically prohibited the use of government funds for the promotion of of gun control. Fearing funding cuts, the government agencies that hand out grants to researchers instated a self-imposed ban on any sort of research into firearms.
The CDC has funded no studies directly related to firearms, while the NIH has been only slightly less cautious — despite a 2013 memorandum from President Barack Obama instructing both agencies to begin funding research into gun violence. More often than not, researchers rely on their own resources to conduct their work.
For many people, leprosy brings to mind Biblical stories of diseased people cast out from society. It’s a condition that today is largely found in developing countries, whereas in other, mostly Western nations it’s a pestilence of the past that was eradicated decades ago. But recent research has shown the disease not only persists in Britain but, perhaps more alarmingly, is also being carried by one of our best loved and most endangered native mammals, the red squirrel.
The study by researchers at the University of Edinburgh and EPFL in Switzerland found red squirrels from England, Scotland and Ireland were infected with leprosy. In particular, a group from Brownsea Island on the south coast of England had a strain of the disease virtually identical to one that infected humans in the middle ages. Read More
When the American painter Abbott H. Thayer published his book Concealing-Coloration in the Animal Kingdom in 1909, he put forth the hypothesis that animals’ colors served one function and one function only: to camouflage.
While that theory has since been disproven (animal colors also play a role in threatening predators and attracting mates), his work made a significant impact on our understanding of camouflage and how it could be used in war. During World War I, both the French and the German militaries relied on his book to develop designs for camouflaging their soldiers, and it became required reading for the U.S. Army’s newly launched unit of camoufleurs. Thayer’s work noted how nature “obliterates” contrast by both blending into its environment and disrupting it by using arbitrary patterns to break up outlines. Read More
“Cancer has been cured a thousand times.”
So says Christopher Austin, the director of the National Center for Advancing Translational Sciences (NCATS) at the National Institutes of Health. Austin should know — as the director of NCATS, his focus is on exactly these kinds of groundbreaking laboratory studies.
His proclamation comes with a significant caveat that will pop the bubbles in your champagne. Austin is so interested in these studies because they all happened in mice, in a lab. When the hundreds of different drugs that made mouse tumors disappear were carried forward to human trials, they went in and came out without doing what they promised. Or worse, they turned out to be toxic. Read More
Back in August, it seemed that Sir Arthur Conan Doyle, the creator of Sherlock Holmes, was cleared of playing any role in one of the greatest hoaxes in scientific history. But in true Sherlockian form, there may still be a twist in this case that appears to be closed. And it’s a fitting discussion on Halloween.
The infamous ‘Piltdown Man’ hoax culminated in 1912 after esteemed geologist Sir Arthur Smith Woodward and amateur archaeologist Charles Dawson announced they had discovered the ‘missing link’ between ape and man. It featured a human-sized skull with an ape-like jaw, and it fooled scientists for 40 years before it was debunked.
So how did Conan Doyle get involved in this, and why should he still remain on the suspect list, despite the latest evidence? Stay with me as I dig deeper into this longstanding controversy. Read More
