Unraveling the Power of Silk

2 days ago | discovermagazine.com | Amy Paturel

David Kaplan has been working with silk for decades, molding and shaping it into scaffolds, sponges, and films. His lab, the Kaplan Lab, is strewn with the substance, stacked with cases of silk cocoons and wads of silk from around the world, all awaiting their transformation into new forms. Kaplan, a biomedical engineer at Tufts University, has studied silk since the 1990s, uncovering ways to build bodily tissues from its fibers.
Thorin the Neanderthal Was One of the Last of These Ancient Humans

Thorin was the name given to a Neanderthal specimen found amongst a small group of Neanderthals that lived between 42,000 years and 52,000 years ago in the Grotte Mandrin, a cave located in southern France. According to a 2024 study in Cell Genomics , Thorin was a Neanderthal found in Eurasia, and he's genetically similar to the Gibraltar Neanderthals, who lived across the continent. Thorin was an adult male, identified through 30 fossilized teeth and bones, and buried at the mouth of the cave.
A Little Ice Age May Have Assisted in the Roman Empire's Collapse

Rocks on the coast of Iceland couldn't possibly tell us anything about the Roman Empire. Or could they? According to a study in , a collection of rocks on Iceland's coast reveals the severity of the Late Antique Little Ice Age - a period of climate change that may have contributed to the Roman Empire's collapse.
Mars May Have Experienced a Great Dying Event Similar to Earth's

NASA's Curiosity Mars rover has reported "evidence of a carbon cycle on ancient Mars," according to a recent press release . These new findings could help researchers better understand if and how Mars ever supported life. As Curiosity continues to traverse the Gale Crater, researchers are working to better understand the Red Planet's habitability and climate transitions that lead to the environment it has today. The findings have been published in the journal .
Yellowstone's Magma Reservoir Reveals Insights Into Future Volcanic Activity

1 week ago | discovermagazine.com | Sam Walters

Ask any geologist about the magma reservoir beneath Yellowstone, and they'll tell you that it's there. But where, exactly, is a lot tougher to explain. Though the existence of the magma reservoir beneath Yellowstone has been well-established, its location and contents are a lot less clear.
The Tiny Dolní Věstonice Portrait Head Gives Us a Glimpse into Ancient Society

1 week ago | discovermagazine.com | Sara Novak

During the late Paleolithic Period, a group of mammoth-hunting ancient humans set up camp in the Dolní Věstonice region of what is now the Czech Republic, and this specimen is a representation of the culture that took place there. The portrait head seems to show a woman with engraved eyes and other individualized features and a face that tells us a story. The oval face, shapely turned-up nose, full lips, and eyes are portrayed as uneven, a detail which leaves us to wonder why.

Made of chopped cabbage that is fermented in salt, sauerkraut is full of fibers, vitamins, and minerals that support the body, according to a 2014 analysis in Integrative Medicine & Health . In fact, among these nutrients are vitamins C and K, which support the immune system and aid in healthy healing.
Do Realistic AI Avatars Invoke the Uncanny Valley?

1 week ago | discovermagazine.com | Monica Cull

Seeing human-like robots, dolls, and AI-generated faces can trigger eerie, put-off feelings towards the figure, a phenomenon known as the uncanny valley. Though these figures look almost human, there is just something slightly off about them. It could be the unblinking eyes, unnatural stillness, or - for AI-generated figures - poorly synced facial and lip movements.
Lasers Could Help Detect Nano- and Microplastics in Bodily Fluids

1 week ago | discovermagazine.com | Monica Cull

From the food we eat to the air we breathe, microplastics and their even smaller equivalent - nanoplastics - are just about everywhere. And while the body may expel some of the plastics we've consumed, there are still plenty that linger in our blood and organs, leading to other health issues. Recent research , as part of the FFG bridge project Nano-VISION, uses a new sensor platform that allows for a laser to be shone at clear, bodily fluids.
In the Deep Ocean, Dark Oxygen May Mysteriously Emanate from the Bottom

1 week ago | discovermagazine.com | Cody Cottier

A new study published in Nature Geoscience in July 2024 suggests it's unclear what causes dark oxygen, but a possible source could be polymetallic nodules. This discovery could rewrite our understanding of how aerobic (oxygen-respiring) life evolved on Earth. And it could even point to new possibilities for extraterrestrial life, perhaps on Saturn's watery moons. The traditional story of Earth's oxygen is simple: There was none until the first photosynthesizers evolved 3.4 billion years ago.
