Some 13,000 years ago, just as the last Ice Age was receding, ancient humans were returning to a camp in the Great Lakes region to process hunted animals and sharpen up their hunting weapons.In present day, a local amateur archaeologist named Thomas Talbot discovered the ancient campsites when he kept finding Clovis tools and rock scrapings in a field near Mendon in southwestern Michigan. Brendan Nash, an archaeologist at the University of Michigan, and a team then started an excavation at what ...read more
One of the sadly neglected problems in modern science is the question of how best to keep beer cool once it has been poured into a glass. Now one scientist has come up with a novel solution by developing a mathematical model that determines the optimal shape of a beer glass that keeps beer cool.The problem is well known to generations of beer drinkers the world over. As soon as beer is poured into a glass, it starts to warm up. So an important goal is to minimize the heat entering the beer so th ...read more
Learning that a shiny rock is fool’s gold rather than the valuable mineral is generally cause for disappointment. But for scientists who discovered a new 450-million-year-old arthropod preserved in iron pyrite, the substance could be considered priceless.Fossils of ancient arthropods — a group of animals including spiders, centipedes, and insects — are especially rare, because they are made up primarily of soft tissue, which usually starts decaying days after death. Due to some rare geoche ...read more
Imagine holding a piece of the early solar system in your hands — a 4.5-billion-year-old artifact that predates our planet. Thanks to the Apollo missions of the 1960s and 70s, and China’s 2024 Chang’e-6 mission, researchers now have the opportunity to hold, and study, lunar samples that provide a unique glimpse into the distant past.Moon rocks, brought back to Earth by NASA's Apollo missions and China's Chang’e probes, are far more than ordinary space debris. These samples hold invaluabl ...read more
In 1997, a team of scientists reared several chicken eggs in two different incubators: one was a normal, sterile incubator, while the other one was infused with the sweet, fruity aroma of strawberries. Sometimes, they even rubbed the experimental group with strawberry aromas straight on the shell.Once the chicks hatched, much to the scientist’s amusement, the few baby chickens that had been exposed to strawberries while still embryos loved the scent and the taste of it: they liked strawberry-f ...read more
One of the big ideas of modern science is that small things can sometimes have huge, irreversible consequences. These so-called tipping points crop up in all walks of life, from economics and finance to human health and the environment. Indeed, they are a fundamental feature of what scientists call complex systems.In an effort to better understand tipping points, scientists have invested much time and effort into simulating complex systems like the climate and the economy, and then gathering dat ...read more
We don’t know how language first began. The first writing didn’t occur until around 3200 B.C.E., and we know that spoken language came before that. Some experts contend that it started with hand gestures along with sounds and signals that, in short order, gave humans a leg up when it came to survival.Fast forward a few thousand years, and the ancients were steeped in it. The Ancient Greeks, for example, were known for their linguistic achievement. By this time, an abundance of languages woul ...read more
Zombies strike fear into our hearts – and if they’re persistent, eventually, they get inside our heads. Animals taken over by zombies no longer control their own bodies or behaviors. Instead, they serve the interests of a master, whether it’s a virus, fungus or some other harmful agent.The term “zombi” comes from Vodou, a religion that evolved in the Caribbean nation of Haiti. But the idea of armies of undead, brain-eating human zombies comes from movies, such as “Night of the Living ...read more
Bottlenose dolphins in Sarasota Bay in Florida and Barataria Bay in Louisiana are exhaling microplastic fibers, according to our new research published in the journal PLOS One.Tiny plastic pieces have spread all over the planet – on land, in the air, and even in clouds. An estimated 170 trillion bits of microplastic are estimated to be in the oceans alone. Across the globe, research has found people and wildlife are exposed to microplastics mainly through eating and drinking but also through b ...read more
Fusion energy has the potential to be an effective clean energy source, as its reactions generate incredibly large amounts of energy. Fusion reactors aim to reproduce on Earth what happens in the core of the Sun, where very light elements merge and release energy in the process. Engineers can harness this energy to heat water and generate electricity through a steam turbine, but the path to fusion isn’t completely straightforward.Controlled nuclear fusion has several advantages over other powe ...read more
