More than half of stroke survivors do not receive rehabilitation after the first days of advanced stroke care. Instead of living for months or years with visible or hidden disabilities, stroke survivors can take advantage of new techniques of advanced rehabilitation to improve their function and freedom.One condition, called spatial neglect– in which a person’s three-dimensional reality and spatial movements are distorted on one side – is particularly underdiagnosed and undertreated among ...read more

In every major body of water in the world, there are sunken ships resting on the seafloor. Near the coast of North Carolina, for example, there is a graveyard of ships torpedoed during the Second World War by German submarines. And in the Great Lakes, an estimated 6,000 to 10,000 ships have been lost at sea.These wreckages, however, weren’t the intent of the captain or crew. Most ran into bad weather or enemy crosshairs. However, on the coast of a Hawaiian island, there is a ship graveyard whe ...read more

Helicopters draw a lot of attention with their almost magical ability to hover, fly in any direction and operate without runways. They also help save many lives, often dramatically, with their extensive use in all-weather military missions, ambulance duties and search-and-rescue roles.When things go wrong, dramatic images and news stories about helicopter accidents grab the public’s attention. This is especially true when high-profile celebrities or government officials are involved.However, m ...read more

Humans likely butchered 6-foot-long armadillo-like animals over 20,000 years ago, according to a report in PLOS ONE. These findings not only represent an interesting dietary choice (and make one wonder just what ancient armadillo must have tasted like), but they also bump back the time of known human occupation of South America by about 6,000 years.Pleistocene ButchersScientists analyzed cut marks on parts of the pelvis, tail, and body armor of a creature called glyptodont, also referred to as N ...read more

Isaac Newton would never have discovered the laws of motion had he studied only cats.Suppose you hold a cat, stomach up, and drop it from a second-story window. If a cat is simply a mechanical system that obeys Newton’s rules of matter in motion, it should land on its back. (OK, there’s some technicalities — like this should be done in a vacuum, but ignore that for now.) Instead, most cats usually avoid injury by twisting themselves on the way down to land on their feet.Most people are not ...read more

When I was in middle school, my biology teacher showed our class the sci-fi movie “Star Trek III: The Search for Spock.”The plot drew me in, with its depiction of the “Genesis Project” – a new technology that transformed a dead alien world into one brimming with life.After watching the movie, my teacher asked us to write an essay about such technology. Was it realistic? Was it ethical? And to channel our inner Spock: Was it logical? This assignment had a huge impact on me.Fast-forward ...read more

The problem of misinformation isn’t going away – and may be getting worse, in the wake of the assassination attempt on former President Donald Trump. Internet platforms like Facebook and X have taken some steps to curb its spread and say they are working on doing more. But no method yet introduced has been completely successful at removing all misleading content from social media. The best defense, then, is self-defense.Misleading or outright false information – broadly called “misinform ...read more

Blue whales are the Earth’s largest species and can stretch beyond 100 feet in size — even their young measure at above 20 feet on average. Great white sharks, meanwhile are quick, powerful, and highly efficient predators. What happens when these two face off and do great white sharks actually pose a threat to these true titans of the ocean? The short answer, says Chandra Salgado Kent, marine ecologist and associate professor at Edith Cowan University, in most cases, likely not. Fit adult bl ...read more

In the wild, animals fight over mating, food, territory, and to protect their young. Even when living in the same environment, not all animals fight each other. We couldn’t help but wonder what would happen if these animals interacted on the battlefield. Let’s look at how some formidable animals in the wild might do in a matchup based on their skills and strengths.1. Tiger vs. Lion(Credit: Volodymyr Burdiak/Shutterstock) Tigers are found in Asia, while most lions primarily live in Africa. Wh ...read more

During the summer of 1998, shifting sands on a beach on the east coast of England exposed an ancient monument. Fifty-five oak posts had been situated in a 15-foot-wide circle, and an upturned tree stump was planted in the middle.Scientists were able to date the monument to 2050 B.C.E. during the Bronze Age. While the monument has been nicknamed Seahenge, scholars referred to it as Holme I, named after the location where it was found.“It is not a henge, neither is Stonehenge for that matter, a ...read more
