Feathered tyrannosaurs? No, thank you. These dinosaurs didn’t need no stinkin’ feathers, and a new study backs me up on that. (Credit David Monniaux/Wikimedia Commons)
It’s a good day here at Dead Things: A new study provides a nice big nail in the coffin of the notion that T. rex and its kin ran around all kitted out in feathers. Lovers of old-school, scaly dinosaur renderings, rejoice!
Maybe I’m showing my age, but when I was learning about dinosaurs they were ta ...read more
Cook Pines line a walkway in Sri Lanka (Credit: eFesenko/Shutterstock)
In a world of upright trees, one species dares to be different.
Cook pines, a type of tall, slim evergreen native to a remote island in the South Pacific, at first glance appear to be falling over. Many tilt precariously to the side as if caught in a heavy wind, though no breeze ruffles their foliage. Though it may seem the result of chance, observe a stand of Cook pines, especially in locations far from their native habita ...read more

When you hear someone laugh behind you, you probably picture them on the phone or with a friend – smiling and experiencing a warm, fuzzy feeling inside. Chances are just the sound of the laughter could make you smile or even laugh along. But imagine that the person laughing is just walking around alone in the street, or sitting behind you at a funeral. Suddenly, it doesn’t seem so inviting.
The truth is that laughter isn’t always positive ...read more

What’s a more healthful option for a sandwich: industrially processed white bread, or artisanal whole-grain bread?
To those who seek clear-cut, black-and-white answers to burning questions like this one, we apologize preemptively. The answer is both; it simply depends on who’s eating it.
The Better Bread?
That conclusion is from researchers at Israel’s Weizmann Institute of Science who recently compared the short-term health effects of switching ...read more

We all know that feeling: the burning sensation as we slice into a fresh onion, eyes watering and wincing to relieve the stinging. There are claims that home remedies can solve this problem, including burning a candle, putting the onion in the freezer before chopping, or cutting the onion underwater. In this article we will investigate the culprit behind our onion tears and a possible scientific resolution that has emerged in the 21st centu ...read more

You have a bit of your mother in you, literally.
When scientists performed biopsies of young adults’ organs, they’ve found maternal cells embedded in hearts, kidneys, and liver. This phenomenon, called microchimerism, is caused by a small number of cells passing through the placenta during pregnancy. The ...read more

Astronomers recently announced the discovery of the hottest known giant exoplanet.
Sitting 650 light years away in the constellation Cygnus, Kelt-9b is a scorching ball of gas roughly three times the size of Jupiter. Temperatures there are estimated to reach 7,800 degrees Fahrenheit, hot enough that the planet’s atmosphere may be evaporating away i ...read more
Ten years ago, ketamine was a drug best known for its popularity on the rave scene. Yet it has since enjoyed a remarkable rebirth – as an antidepressant. Starting out with a handful of small clinical trials, there are now numerous reports that ketamine produces rapid antidepressant effects. In the US, various clinics have sprung up offering ketamine treatment to depressed patients – at least the ones able to pay the bill, because insurance doesn’t tend to cover it.
Now, a grou ...read more
The Earth from the Moon on Apollo 8, 1968. NASA.
You might think the story of the Space Race is straightforward. That NASA was created one day so the United States could start sending things and people into space, and when it turned out that the Soviet Union had more advanced technologies — it did get the first satellite and human into orbit — President Kennedy decided we should go to the Moon. By the end of the decade, no less. Then NASA did what it does best: solved the problem. I ...read more
