The scene was stranger than it looked, even by Las Vegas standards: Two young men pull up in a U-Haul truck to a motel outside the city. They check in and move a cooler into their room. They appear to be handling something of importance, and look to see if the ice needs replenishing. Inside […]
In our teens and 20s, many of us feel unstoppable. But after age 30, everyday life starts to get a little harder. Knees ache, hangovers last two days, younger family members begin to outrun us and we can’t remember what we did with our keys. With aches, pains and busy schedules, exercise can be a […]
When asked the right way, a savvy bird species steers African hunter-gatherers to honey. All it takes is a loud trill followed by a grunt that sounds like “brrr-hm.” Birds known as greater honeyguides (Indicator indicator) lead hunter-gatherers in Mozambique to honey-rich bees’ nests after hearing humans make this signature call, say evolutionary ecologist Claire […]
In the space business, weight and size are what run up the bills. So imagine the appeal of a telescope that’s a tenth to as little as a hundredth as heavy, bulky and power hungry as the conventional instruments that NASA and other government agencies now send into space. Especially alluring is the notion of […]
Rare evidence has emerged that humanborne infectious diseases moved across Asia around 2,000 years ago via the famous Silk Road. Clues to this ancient illness spread come from cloth wrapped around the ends of sticks once used by travelers as the equivalent of toilet paper. Preserved feces on cloth caps of sticks previously excavated from […]
Like an interplanetary parfait, the dwarf planet Ceres appears to have layers. A pliable outer shell of minerals, ices and salts encapsulates a core of solid rock, a new study suggests. This first peek inside Ceres — courtesy of NASA’s Dawn spacecraft — can help researchers explain some mysteries on the surface and provide insight […]
New investigations of England’s infamously fraudulent Piltdown Man fossils reveal a mix of clever and clumsy methods used by one man to fool early 20th century scientists for 40 years. Lawyer and amateur archaeologist Charles Dawson modified orangutan and human bones to resemble what scientists of the time anticipated a “missing link” between apes and […]
Primates may have some high-flying relatives. Colugos, small mammals that glide from treetop to treetop in forests throughout Southeast Asia, have an evolutionary history that’s long been debated. Their teeth look similar to tree shrews’ teeth, while other skull and genetic features resemble those of primates. (Past studies have even linked colugos to bats and […]
A large study of human genetic variation finds more than 7 million spots where one person’s DNA can differ from another’s. Analyses of such variants, compiled from cataloging the genes from more than 60,000 people, are already offering doctors helpful insights into diseases such as schizophrenia and some heart conditions. Researchers from the Exome Aggregation […]
COLUMBIA, Mo. — If you find a daddy longlegs in your house, don’t be scared. “Daddy longlegs are actually pretty docile animals when it comes to interacting with humans,” says evolutionary biologist Kasey Fowler-Finn, who studies the arachnids at St. Louis University. Specifically, she studies daddy longlegs sex. She is using this common group of […]
