How Does a Chimpanzee Eat a Tortoise? By Smashing It Like a Coconut

As omnivorous creatures, chimpanzees eat all sorts of things, including fruits, termites, tiny rodents, and even full-grown monkeys. As for chimps eating reptiles, that’s completely unheard of—until now. Unprecedented observations have uncovered a community of chimps in Gabon that regularly consume tortoises.Read more...

How Are Doves and Sparrows Ending Up Inside Baby Sharks?

Back in 2010, scientists were monitoring a shark population on the Mississippi-Alabama border. They had hauled up a small tiger shark to tag when something strange happened: It puked up feathers. A DNA analysis revealed that the shark had eaten a brown thrasher, a speckled migratory songbird related to the…Read more...

Like the emperor’s new clothes, DNA kits are a tailored illusion

Most people remember the emperor: a vain ruler, swindled into paying for a nonexistent magical garment, parades in public, only to be embarrassed by a little boy. To me, the story is really about the swindling tailors. Audacious, imaginative, their true product is a persuasive illusion, one keyed to the vulnerabilities of their target audience. In contemporary terms, the story is about marketing; and as such, the tale is tailor-made for an examination of genetic ancestry tests, because these too...

Pushy bonobo mothers help sons find sexual partners, scientists find

High-ranking mothers lead sons to groups of females and keep guard while they mateTheir mothers are so keen for them to father children that they usher them in front of promising partners, shield them from violent competitors and dash the chances of other males by charging them while they are at it.For a bonobo mother, it is all part of the parenting day, and analysis finds the hard work pays off. Males of the species that live with their mothers are three times more likely to father offspring t...

How A.I. will liberate doctors from keyboards and basements

Machines can help doctors by spotting abnormalities in X-rays or MRA scans that the physicians themselves may have missed. A.I. can also help physicians by analyzing data and, through the use of algorithms, produce possible diagnoses. The freed up time, as doctors make their rounds, can help physicians establish better connections with their patients, which in turn can lead to better treatment plans.

Nanotechnology vs. cancer: How tiny particles sniff out the deadly disease

Cancer is an aberrant function of a normal cell, where the regulators of that cell's dividing are broken and the cell starts to divide without regulation. Left to its own devices, that dividing without regulation will overcome the entire body.Until we have a cure, early detection is the holy grail. MIT professor Sangeeta Bhatia is currently devising a simple urine test that works just like a pregnancy test to detect cancer the moment it starts.How does it work? Nanoparticles are injected into th...

Feral Parrots Are Taking Over America

Visitors to Chicago’s Hyde Park or New York’s Green-Wood Cemetery may be surprised to hear the raucous squawks of lime-green monk parakeets. These birds, descendants of escaped pets, have managed to create thriving colonies in these cities despite the annual cold weather. It turns out they’re far from unusual—escaped…Read more...

Nanotechnology vs. cancer: How tiny particles sniff out the deadly disease

In the United States, smoking cessation has resulted finally in a reduction of deaths from cancer. However, even if we were to have all the vaccines that are prescribed, and exercise all of the preventions, cancer would still be with us.Cancer is an aberrant function of a normal cell, where the regulators of that cell's dividing are broken and the cell starts to divide without regulation.

This Bird Went Extinct, Then Evolution Recreated It

Sometime between 136,000 and 240,000 years ago, a flock of awkward, leggy birds took off from Madagascar and arrived at a pristine island in the Aldabra atoll 250 miles away. “This is nice,” they may have thought—there were no predators, and the birds colonized the island. Without the threat of predation, they…Read more...

Will There Ever Be New Colors That We Can See?

When brain chips break big, and commercial tech giants start sifting our thoughts and swapping cherished memories for subscription wine box ads, there will be plenty of reasons to be skeptical.

We Have to Do Something About Outdoor Cats
