The world's first pandemic, known as the Plague of Justinian after the sitting Byzantine emperor, killed an estimated 25 to 100 million people between a.d. 541 and 750... historical sources from the period suggest that it may have begun around Pelusium, Egypt, before spreading rapidly throughout the Middle East and the Mediterranean world. According to a statement released by the University of South Florida (USF), researchers participated in an interdisciplinary study that has uncovered -- for the first time -- direct genomic evidence pinpointing the bacterium Yersinia pestis as the cause of the plague. The team sequenced genetic material from...

For the first time in the U.S., an identical twin has been convicted of a crime based on DNA analysis. The breakthrough came from Parabon Nanolabs, who’s scientists used deep whole genome sequencing to identify extremely rare “somatic mutations” that differentiated Russell Marubbio and his twin, John. The results were admitted as evidence in court, making last week’s conviction of Russell in the 1987 rape of a 50-year-old woman a landmark case. Case background On Dec. 19, 1987, the victim, a 50-year-old woman, was working as a clerk at a gas station in Woodbridge, Va. She left the store to...

Facetotectans (aka y-larvae) have been a mystery since their discovery in the 1800s. Scientists are unsure of what they grow up to become, but we now know where these crustaceans fit in the tree of life. This image shows a cypris larvae, or y-cyprid. Credit: Niklas Dreyer Y-larvae, mysterious crustaceans related to barnacles, may be parasitic and are key to understanding barnacle evolution. When most people think of barnacles, they imagine shell-like organisms clinging to boats, docks, or even whales. Yet some barnacles go far beyond passive attachment — they can actually invade and take over their hosts. “Instead of...

Spaceflight has a broad impact on the way our body functions — and that includes our reproductive systems. Indeed, to get a better idea of how future pregnancies and new generations born to humans beyond Earth will be affected, scientists need to examine how well our reproductive germ cells and stem cells respond to potentially harmful factors, like radiation and microgravity. Researchers from Kyoto University in Japan did just this: They froze the spermatogonial stem cells of mice through a process called cryopreservation, then kept them on the International Space Station (ISS) for six months. Once back on Earth, researchers...

BUENOS AIRES - They look like ordinary foals, docile with honey brown coats and white facial patches, content to spend their days munching alfalfa in a cordoned-off pasture in rural Buenos Aires province. But these five 10-month-olds are the world’s first genetically edited horses: cloned copies of a prize-winning horse named Polo Pureza, or Polo Purity, with a single DNA sequence inserted using CRISPR technology with the aim of producing explosive speed. Kheiron Biotech, the Argentine company that created the horses, says gene-editing has the potential to revolutionize horse breeding. While cloning creates a genetically identical copy, CRISPR functions as...

Bearded dragons are famous for their ability to change sex depending on heat and genes. Two new genome projects have revealed the likely master gene, Amh, behind this switch — finally solving a reptile mystery that has baffled scientists for years. Credit: Shutterstock Scientists have finally cracked one of the strangest mysteries in reptile biology: how bearded dragons decide their sex. Breakthrough Genomes Reveal Bearded Dragon’s Secrets Two separate research teams have now released near-complete reference genomes of the central bearded dragon (Pogona vitticeps), a lizard species that ranges widely across central eastern Australia and is also a favorite pet...

See the so-called evidence that allegedly proves Bigfoot's existenceA CAMPER believes he's unlocked the secret behind one of the world's most famous cryptids after finding a so-called Bigfoot corpse. Charles “Snake” Stuart, also known as the Bigfoot hunter, presented his stunning findings in a bizarre exhibition on Wednesday. He brought the massive 8-foot-tall hairy body to the New York State Fair in Syracuse and displayed it behind a glass case. The grisly figure was placed on top of a wooden coffin in a dark room with spooky growls playing on speakers. Beside the alleged body is a video of Star...

During the last Ice Age, modern humans had ongoing encounters with more than one variety of now-extinct Pleistocene-era hominin.Those encounters, according to new research, not only resulted in interbreeding between homo sapiens and other types of archaic humans -- they may have helped some of the earliest arrivals in North America survive...The earliest arrival of anatomically modern humans in North America has been a subject of intense debate for several decades. Increasingly with time, discoveries by archaeologists have continued to push back the time scales on when those arrivals began, with initial estimates of early human dispersals into North America...

The use of DNA to arrest Bryan Kohberger for the murder of four college students in Idaho reminds me that it's time to bring the death penalty back in a big way. Notwithstanding the absence of a single example, the possibility of executing the "wrong man" has been the left's main line against the death penalty for decades. It's the only argument that has ever lessened Americans' support for capital punishment. Well, guess what? Thanks to the miracle of DNA, now there's no risk! The murderer can usually be identified with greater than 99.99% accuracy. Good news, right? Nope! As...

New findings in the Idaho college murder case have emerged. Attorneys for Bryan Kohberger—who has been accused of fatally stabbing University of Idaho students Madison Mogen, Kaylee Goncalves, Xana Kernodle and Ethan Chapin at a rental home in 2022—said an investigator discovered DNA evidence from three individuals under Mogen's fingernail.

One of the coeds butchered at the University of Idaho in 2022 had DNA from three different people under her fingernails, according to bombshell newly unsealed court documents. However, lawyers for murder suspect Bryan Kohberger say a test to match the traces to their client came back with inconclusive results. As a result, the evidence should be excluded from his trial, they argued in a court filing that was made public on Tuesday The samples taken from the fingernails of 23-year-old Madison Mogen offer yet another twist in the case of the four students who were horrifically stabbed to death...

Let’s face it, the sea is full of proper freaky looking creatures, from Barbie lobsters to disco worms and everything in between. However, normally in the shark world, the species relies on sharp teeth and speed to make an impression. Well, one shark species has taken a rather different approach from stealthy gray. For the first time, a nurse shark has been recorded in the Caribbean being bright orange. The nurse shark (Ginglymostoma cirratum) was seen in Costa Rican waters during a sport fishing trip near Tortuguero National Park last year, and the photos were shared on its Facebook page....

The mystery behind a missing British researcher in Antarctica has been solved. The remains of Dennis Bell, who went missing in Antarctica, have been found on a glacier. Bell went missing in 1959 in Antarctica while working as a meteorologist for the Falkland Islands Dependencies Survey. CBS News reported more in-depth details on the discovery of the researcher: The remains of a British researcher who vanished in 1959 in Antarctica when he was 25 years old were discovered amid rocks near a receding glacier and identified using DNA analysis, the British Antarctic Survey said Monday. Dennis “Tink” Bell had been...

On May 16, 2025, the remains of a human foot inside a hiking boot were found in a shoe on the shores of Fishlake, Utah. Investigators were able to determine the hiking boot was only made in 1996 for one year. Sevier County Sheriff’s Office (Utah) had a cold case where an individual from Washington, Utah had gone missing in September 1997. That individual was David White. White intended to go fishing with friends and had rented a nearby hotel room. Those plans fell through so White, an avid fisherman, went fishing solo. His boat was later reportedly found trolling...

The ancestors of all modern humans split off from a mystery population 1.5 million years ago and then reconnected with them 300,000 years ago, a new genetic model suggests. The unknown population contributed 20% of our DNA and may have boosted humans' brain function...In a study published Tuesday (March 18) in the journal Nature Genetics, researchers presented a new method of modeling genomic data, called "cobraa," that has allowed them to trace the evolution of modern humans (Homo sapiens).By applying their new method to modern human DNA data published in the 1000 Genomes Project and the Human Genome Diversity Project,...

The modern potato exists thanks to a 9-million-year-old hybrid between tomato-like and potato-like plants. Credit: Shutterstock ========================================================================== Scientists have finally uncovered the ancient secret behind the potato’s origin—and it involves an unexpected genetic romance. About 9 million years ago, a wild interbreeding event occurred between a tomato-like plant and a potato-relative in the Andes. This rare hybridization gave rise to the first tuber-forming plants. Ancient Hybrid Sparked the Potato’s Origins An international team of scientists has discovered that the modern potato originated from a natural crossbreeding event between tomato plants and potato-like wild species in South America around 9 million...

...archaeological evidence at one site called Madjedbebe in the far north of Australia's Northern Territory suggests the area may have been occupied much earlier -- at least 65,000 years ago.Archaeologists recovered human-made artifacts, including stone tools and ocher "crayons," from the Madjedbebe rock shelter and published their findings in a 2017 study. One difficulty in dating the artifacts, however, was the copious amount of sand on the floor of the rock shelter, which can move easily and cause artifacts to fall farther down, making them look older than they are.Although the research team took steps to counteract this issue and...

A 4-year-old boy who was found dead in Lorton, Virginia, more than 50 years ago, and whose name has remained a mystery, has finally been identified after a flood of tips, a series of DNA tests and decades of twists and turns. Fairfax County police Chief Kevin Davis announced the breakthrough Monday, saying the child’s identification has led police to two people who are believed to have been involved in his killing, and another missing boy whose body has never been discovered. The case of the boy, identified as 4-year-old Carl Matthew Bryant, confounded police and the public for decades....
