Bedbugs sucked blood in the age of dinosaurs

Scientists originally thought bedbugs evolved on bats roughly 50 million years ago. New research used DNA to map the bedbug ancestry and found the species evolved as far back as the Cretaceous. The researchers hope that understanding how bedbugs evolve will help us curb their ability to spread and transmit diseases to people. None An international team of scientists have been on a quest. They have traveled to Africa, South America, and South East Asia. They have scaled cliff faces, explored shad...

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...

Canadian Arctic fossils are oldest known fungus on Earth

Fungus is half a billion years older than previous record holder found in WisconsinTiny fossils found in mudrock in the barren wilderness of the Canadian Arctic are the remains of the oldest known fungus on Earth, scientists say.The minuscule organisms were discovered in shallow water shale, a kind of fine-grained sedimentary rock, in a region south of Victoria island on the edge of the Arctic Ocean.

How to change the mind of an anti-vaxxer

Talking to people who have experienced vaccine-preventable diseases changes minds. Seventy percent of Brigham Young University students shifted their vaccine-hesitant stance. This research arrives during a year in which 880 measles cases have been identified in America. None There is no greater teacher than experience — or the experience of others, it turns out. Educating the anti-vaxx population has proven to be challenging, yet a new intervention conducted by researchers at Brigham Young Univ...

Mother bonobos, too, pressure their sons to have grandchildren

Mother bonobos have been observed to help their sons find and copulate with mates.The mothers accomplish this by leading sons to mates, interfering with other males trying to copulate with females, and helping sons rise in the social hierarchy of the group.Why do mother bonobos do this? The "grandmother hypothesis" might hold part of the answer. None Like mother, like monkey. Bonobo mothers, it turns out, can also be quite pushy in their quest to become grandmothers, according to a new study pub...

New Breakthrough Means We Can Finally Detect the Color Red in Ancient Fossils

Some 3 million years ago, a tiny mouse featuring reddish fur on its back and a white belly scurried across the landscape of what is now Germany. We know this thanks to a remarkable new breakthrough in which reddish color pigment was detected in an ancient fossil—a scientific first.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.

DNA Script picks up $38.5 million to make DNA production faster and simpler

DNA Script has raised $38.5 million in new financing to commercialize a process that it claims is the first big leap forward in manufacturing genetic material. The revolution in synthetic biology that’s reshaping industries from medicine to agriculture rests on three, equally important pillars. They include: analytics — the ability to map the genome and understand the function of different genes; synthesis — the ability to manufacture DNA to achieve certain functions; and gene editing — the ...

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...
