One of the great achievements of modern science was the human genome project to map the sequence of genes in human DNA. The project produced unprecedented insight into the function of genes, their role in human health and the nature of life itself.And yet the human genome project was just the beginning. Armed with the sequence of genes in DNA, life scientists now want to know how the extraordinarily rich complexity of life emerges from this code. Closely linked and just as puzzling is how small ...read more
A 200-million-year-old piece of fossilized poop has provided some of the earliest evidence yet that modern-day parasites plagued the age of the dinosaurs.A Thai-French joint paleological survey recovered the “coprolite” in 2010 while working at an archaeological site in the central part of Thailand. The dropping was smooth, gray, cylindrical and curved slightly to one side – a simple object, but a potential “treasure trove,” according to a statement.What Did the Coprolite Contain?Later ...read more
After a retired speech-language pathologist had a stroke, he struggled to articulate his thoughts, even though he knew what he wanted to say. His wife didn't understand the source of his difficulties until a clinician showed her a video that explained what her husband wished he could tell her: His stroke caused apraxia.Apraxia is a term used to describe a list of neurological disorders that impact speech, movement or gestures. Clinicians have observed apraxia for centuries, but they still don ...read more
Half a billion years ago, in the earliest days of animal life, there were few undersea predators. A strange shrimp-like creature that grew up to 6 feet in length and wielded twin claws served as top predator. Meanwhile, small chaetognath worms snapped at prey with a mouth that bristled with spines.But these sparse ranks have just gotten a little less sparse.A new fossil discovery has confirmed that a much more familiar predator, a type of jellyfish, also stalked the oceans more than 500 million ...read more
Living on the same planet that we evolved on, it can be easy to take things for granted. We have an abundance of fuel and fresh water, plants and animals for food, and an atmosphere with plenty of oxygen.Yet we also have plans to send people off-world. In the coming decades, humans will set out to explore our solar system in greater detail than ever before; we have plans to erect a base on the moon through NASA’s Artemis mission, and even send the first people to Mars.Is There Oxygen in Space? ...read more
It was the first epoch after the age of dinosaurs in a part of the world that had recently recovered from an asteroid blast of epic magnitudes. The blast birthed the tropical rainforests along the equator that exist today. A landscape that was damp and swampy, covered in dense tropical foliage — ample places for Titanaboa to hide.What Was the Largest Snake in the World?Titanaboa, the largest snake in the world, lived during the Paleocene around 58 to 60 million years ago. It thrived alongsid ...read more
A predatory species of fish has adapted to the destruction of its local coral reef by using another fish, the peace-loving parrotfish, for cover, according to a new study.Researchers and local divers in the Caribbean have long talked about the tactic and painted a similar picture: The long, thin trumpetfish swims alongside the more rounded parrotfish (or another reef fish) as if seeking cover from it. But does this really help the trumpetfish to hunt?To find out, the researchers from the univers ...read more
Are we alone in the universe? There are good reasons to suspect that we have company.After all, the universe is exceptionally large, with possibly billions of Earth-like planets in our Milky Way galaxy, which is but one of trillions of galaxies in the universe.The ingredients for life, as far as we know, are common. And humans on Earth have proven life is capable of evolving to a point of technological complexity which could make our presence visible to anyone out there looking.But could we reco ...read more
The release of Oppenheimer, Christopher Nolan’s sprawling study of the man known as “the father of the atomic bomb,” has propelled the world-shifting work of a scientist to cinema’s front stage. Tracking the life of J. Robert Oppenheimer through his time as director of the Manhattan Project and beyond, the film explores the complexities of its protagonist’s character and conscience alongside the thorny union of science and morality.5 Movies About ScientistsIf that tangled, three-hour ...read more
Titanosaurs, a diverse group of long-necked sauropod dinosaurs, were found on every continent, including Antarctica, in their Cretaceous heyday. They lived right up until the end of all other non-bird dinosaurs, when the Chicxulub asteroid struck the Yucatan Peninsula about 66 million years ago.Paleontologists have discovered dozens of distinct titanosaurs, many of them relatively recently in fossil beds in South America. Nearly all of the group are massive, but like other sauropods, these giant ...read more
