One version of the human papillomavirus, which leads to most cases of cervical cancer, evolved in humans as a result of sex with Neanderthal, a new study shows.
The American Cancer Society estimates more than 13,000 women in the United States will be diagnosed with invasive cervical cancer this year and 30 percent will die from the disease. HPV is responsible for nearly every case of cervical cance ...read more

Critically endangered Chinese sturgeon may be even worse off than we thought, reports a team of researchers from the China Institute of Water Resources and Hydropower Research in Beijing.
These ancient fish are anadromous, which means they live in the ocean and migrate up rivers to spawn in fresh water. For the Chinese sturgeon, this annual spawning quest brings them up China’s Yangtze ...read more
Using the ESO’s sensitive GRAVITY instrument, researchers have confirmed that the enormous object at the heart of our galaxy is — as scientists have assumed for many years — a supermassive black hole. (Credit: ESO/Gravity Consortium/L. Calçada)
Scientists have finally confirmed that the massive object at the heart of our galaxy is, in fact, a supermassive black hole.
Researchers used the European Southern Observatory’s sensitive GRAVITY instrument on the Very Lar ...read more

Childhood wasn’t easy for Neanderthals.
A new study of Neanderthal teeth published in Science Advances this week tells us new details about what life might have been like for early hominin children in a rapidly changing environment. It’s an unprecedented look into how our ancient cousins coped with harsh climate conditions and seasonal changes in resource availability.
Also among the findings ...read more

From Ryugu to Bennu, asteroid exploration has been all the rage among astronomers lately. And now, we’re one step closer to exploring some of the most mysterious asteroids in the solar system.
On October 30, NASA announced that they’ve been given the green light to start building Lucy, a spacecraft that will probe Jupiter’s trojan asteroids and is set to launch in October of 2021. On top of giving the g ...read more

Seriously, this gargantuan coffin-like object really was photographed by an astronaut aboard the International Space Station on September 23, 2018.
If you guessed that it is an iceberg, you are right.

A spinal cord injury used to mean life bound to a wheelchair. Now, three spinal cord injury patients are able to walk and even ride a modified bicycle, new research shows. The trio got on their feet again thanks to well-timed and precise electrical stimulation in the spinal cord combined with rehabilitation. The results are just ...read more
The Andromeda galaxy, which researchers think will collide with the Milky Way in billions of years. One new study shows how our galaxy was shaped by a merger with a dwarf galaxy 10 billion years ago. (Credit: NASA JPL)
Our galaxy, perhaps like many in the universe, is a bit of a Frankenstein’s monster. A new study makes a compelling case that a central structure in the Milky Way is actually composed mostly of stars born in another galaxy, brought to us by a long-ago galactic smash-u ...read more

Samuel Morton collected and studied hundreds of human skulls in the early 19th century. By objectively measuring differences in brain size between people from various societies, Morton believed he had used science to prove that white people were intellectually superior to other races.
Modern science has long since shown that brain size isn’t necessarily related to intelligence. Many researchers suspect brain size is ...read more

Having your appendix removed could lower the risk of getting Parkinson’s disease by 20 percent, says a team of researchers in a new study.
Using medical data from a large-scale Swedish database, a team led by scientists from the Van Andel Research Institute in Grand Rapids, Michigan, were able to tease out a connection between a conditio ...read more
