Scientists Found 78,000-Year-Old Neanderthal Footprints That Tell a Story of Survival
Here's what you'll learn when you read this story:
The oldest-known hominin track sites found in southwest Europe provide clues to the hunting patterns of Neanderthals.
Experts believe that along with eating plenty of plants, the ancient population also hunted deer, horses, and rabbits.
Neanderthals were eager to explore neighboring regions to discover mammals which they could add to their diet.
A Neanderthal family, hunting 78,000 years ago along the dunes of what is now modern-day Portugal, was likely stalking a meal of red deer. Today, thanks to the discovery of fossilized footprints—a range of tracks showing an adult male and two children—scientists were able to piece together the family's movements and how they coincided with the wild game the ancient hominin were known to crave.
In a new study published in Scientific Reports, a team of researchers from the University of Lisbon and the Naturtejo UNESCO Global Geopark used optically stimulated luminescence to date prints found on the coastal cliffs of Monte Clerigo, along with a single print left 82,000 years ago, roughly four miles away at Praia do Telheiro.
The footprints along Portugal's shifting coastal environment are considered 'the first two hominin track sites found in the southwestern most region of Europe.'
In the report, the team chronicles five trackways at Monte Clerigo that contain 26 total prints. They were able to determine that three of the tracks were left by an adult male—likely between 5-foot-6 and 5-foot-8 in height—twice from ascending the cliff dune and once descending. The other two tracks were left by children, one likely between the ages of 7 and 9, and the other from a toddler, probably younger than 2 years old.
When the fossilized prints of a red deer were found on the same dune, the researchers came to believe the family was hunting the deer, using the undulating landscape to attempt to sneak up on the prey.
'Tracks of three individuals demonstrate how Neanderthals navigated dune landscapes,' the study authors wrote. It also gives more credence to the belief that coastal environments were used by Pleistocene humans and that they were important areas in 'shaping hominin cognitive and social development.'
The footprints, a combined result of foot anatomy, gait dynamics, and substrate properties, help tell the story of the family, which was likely camping nearby the dunes.
'A review of the Neanderthal coastal sites associated with faunal evidence shows that their diet was primarily centered on cervids [deer], horses, and hares,' the study authors wrote. 'The consistent presence of these mammal taxa highlights their role as reliable food sources, irrespective of the varying environments inhabited by Neanderthals. In addition, the Neanderthal diet also incorporated animals form neighboring littoral habitats, indicating a broad foraging strategy that capitalized on local biodiversity.'
At Monte Clerigo's five trackways, the busiest featured 10 prints in one track.
The single footprint found at Praia do Telheiro, which was dated about 4,000 years older than those found at Monte Clerigo, was that of a 'slim' foot, likely belonging to a female, the authors wrote.
There's no additional evidence to tell if the female at Praia do Telheiro was on the hunt for red deer, horse, or rabbit.

Peacock Feathers Are Stunning. They Can Also Emit Laser Beams
Macro photograph of water drops on a peacock feather. Photograph:Peacock feathers are greatly admired for their bright iridescent colors, but it turns out they can also emit laser light when dyed multiple times, according to a paper published in the journal Scientific Reports. Per the authors, it's the first example of a biolaser cavity within the animal kingdom. As previously reported, the bright iridescent colors in things like peacock feathers and butterfly wings don't come from any pigment molecules but from how they are structured. The scales of chitin (a polysaccharide common to insects) in butterfly wings, for example, are arranged like roof tiles. Essentially, they form a diffraction grating, except photonic crystals only produce certain colors, or wavelengths, of light, while a diffraction grating will produce the entire spectrum, much like a prism. In the case of peacock feathers, it's the regular, periodic nanostructures of the barbules—fiber-like components composed of ordered melanin rods coated in keratin—that produce the iridescent colors. Different colors correspond to different spacing of the barbules. Both are naturally occurring examples of what physicists call photonic crystals. Also known as photonic bandgap materials, photonic crystals are 'tunable,' which means they are precisely ordered in such a way as to block certain wavelengths of light while letting others through. Alter the structure by changing the size of the tiles, and the crystals become sensitive to a different wavelength. (In fact, the rainbow weevil can control both the size of its scales and how much chitin is used to fine-tune those colors as needed.) Even better (from an applications standpoint), the perception of color doesn't depend on the viewing angle. And the scales are not just for aesthetics; they help shield the insect from the elements. There are several types of manmade photonic crystals, but gaining a better and more detailed understanding of how these structures grow in nature could help scientists design new materials with similar qualities, such as iridescent windows, self-cleaning surfaces for cars and buildings, or even waterproof textiles. Paper currency could incorporate encrypted iridescent patterns to foil counterfeiters. There have been prior examples of random laser emissions in everything from stained bovine bones and blue coral skeletons to insect wings, parrot feathers, and human tissue, as well as salmon iridiphores. The authors of this most recent study were interested in whether they could produce similar laser emissions using peacock feathers and hopefully identify the specific mechanism. It wasn't difficult to get the peacock feathers, given how popular they are for decorative and arts and crafts purposes, but the authors did make sure none of the feathers used in their experiments contained impurities (like dyes). They cut away any excess lengths of barbs and mounted the feathers on an absorptive substrate. They then infused the feathers with common dyes by pipetting the dye solution directly onto them and letting them dry. The feathers were stained multiple times in some cases. Then they pumped the samples with pulses of light and measured any resulting emissions. The team observed laser emissions in two distinct wavelengths for all color regions of the feathers' eyespots, with the green color regions emitting the most intense laser light. However, they did not observe any laser emission from feathers that were only stained once, just in sample feathers that underwent multiple wetting and complete drying cycles. This is likely due to the better diffusion of both dye and solvent into the barbules, as well as a possible loosening of the fibrils in the keratin sheath. The authors were unable to identify the precise microstructures responsible for the lasing; it does not appear to be due to the keratin-coated melatonin rods. Coauthor Nathan Dawson of Florida Polytechnic University suggested to Science that protein granules or similar small structures inside the feathers might function as a laser cavity. He and his colleague think that one day, their work could lead to the development of biocompatible lasers that could safely be embedded in the human body for sensing, imaging, and therapeutic purposes.

This Everyday Fruit Is A Hydration Hero—And May Even Protect Against Cancer.
"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." A new scientific paper suggests a common fruit may have been overlooked in its superfood potential. Grapes are a source of more than 1,600 compounds, including antioxidants and other polyphenols, making them a great superfood, the paper states. Dietitians agree. Here's what this means for you. When you think of a 'superfood,' you're probably imagining something exotic and hard-to-find-at-the-grocery-store, like acai or goji berries. But new research has uncovered a humble superfood that might already have a permanent spot in your fridge. Yep, a scientific paper published in the Journal of Agricultural and Food Chemistry argues that we've been sleeping on grapes for far too long. While it's important to point out that the research paper was funded by the California Table Grape Commission, dietitians agree that the argument for grapes as a superfood is spot-on. Here's why. Meet the experts: Jessica Cording, RD, CDN, is author of The Little Book of Game-Changers; Keri Gans, RDN, is author of The Small Change Diet What did the paper find? The scientific paper first analyzes what superfoods are, and points out that grapes are often overlooked in favor of fellow fruits like berries, even though they have similar health benefits. The paper then notes that grapes are a source of more than 1,600 different biological compounds, including antioxidants and polyphenols like flavonoids, anthocyanidins, catechins, phenolic acids, and resveratrol. The paper also highlights more than 60 peer-reviewed studies on grapes and their health benefits, breaking down their potential support of good cardiovascular health. (Among other things, grapes can help relax blood vessels and support health circulation.) The study cites clinical trials that show grapes can support brain health, skin health, gut health, and eye health, too. 'Thus, based on actual scientific data, grapes have earned what should be a prominent position in the superfood family,' the researcher argues. What can grapes do for your health? For starters, grapes are rich in antioxidants like resveratrol, which could support heart health and even reduce inflammation, says Keri Gans, RDN, author of The Small Change Diet. 'They contain about 82 percent water, making them naturally hydrating, plus they provide vitamin C and potassium, which are great for skin and blood pressure.' Jessica Cording, RD, CDN, author of The Little Book of Game-Changers, says she regularly suggests her clients mix in some grapes in their diet. 'The main reasons I recommend grapes to clients—besides their versatility in sweet and savory dishes—are for their content of vitamin C and other antioxidants,' she says. 'Resveratrol is the most well-known antioxidant found in grapes, and it has been noted with anti-inflammatory benefits.' Grapes specifically support heart health, brain health, improved immune system functions, and may even provide protection against some cancers, Cording says. What are antioxidants and polyphenols? Antioxidants are compounds that protect your cells from damage caused by free radicals (unstable molecules that are linked to several diseases), Gans explains. 'Polyphenols, a type of antioxidant found in plant foods, are especially known for their anti-inflammatory properties and heart-healthy benefits,' she says. What are some other great superfoods? The word 'superfood' is a little controversial, and even the paper's author pointed out that there's no agreed-on definition among experts when it comes to what constitutes a superfood. Gans is also wary of using this word to describe foods. 'It suggests one food can work magic, when health is really about your overall eating pattern,' she says. 'That said, nutrient-packed picks like blueberries, salmon, lentils, leafy greens, and nuts all offer powerful benefits.' Apparently, you can add grapes to that list, too!

Check Your Kitchen—Experts Say These 10 Foods Contain The Most Microplastics
"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Microplastics are found in many everyday foods like rice, tea, bottled water, and seafood. Early research suggests microplastics may contribute to health issues like oxidative stress, organ dysfunction, and metabolic or immune disruptions, though more studies are needed. Experts recommend reducing exposure by choosing loose-leaf tea, rinsing rice, avoiding plastic bottles, and opting for minimally processed or non-plastic-packaged foods. Almost everything we eat these days is transported or stored in plastic, and we've all zapped leftovers in the microwave in plastic containers. But you may not have realized that microplastics actually can be found inside the foods we eat. It's actually not a new topic. "Research into the effects of microplastic consumption has been ongoing for several decades," says Stephani Johnson, D.C.N., R.D.N., adjunct professor, Department of Clinical and Preventive Nutrition Sciences at Rutgers, The State University of New Jersey. "However, there is still much to learn regarding the average levels of human exposure, how long microplastics remain in the body, and their associated health consequences. What is currently known is that microplastics are ubiquitous in the environment, making complete avoidance virtually impossible." Studies have found microplastics throughout the human body, including in the brain, heart, colon, placenta, and more. "We are what we eat, and we are eating and being exposed to plastics in our food," Nicholas Mallos, vice president of conservation, ocean plastics, at the Ocean Conservancy, and co-author of a recent study on microplastics in commonly-consumed proteins. "While we need more research to know what exposure levels of plastics are causing human health problems, we should be concerned." What Are The Health Consequences Of Consuming Microplastics? Emerging evidence suggests that potential harm may depend on several factors, including the amount consumed, as well as the type, size, and shape of the microplastic particles. "At the cellular level, studies have shown that microplastics can contribute to oxidative stress, DNA damage, organ dysfunction, and disruptions in metabolic, reproductive, and immune functions, as well as neurodevelopmental toxicity," Johnson says. Unfortunately, there is still much we don't know about microplastics in food. "Our study demonstrates the need for further research to better understand microplastics in the most commonly consumed foods, including precisely where these microplastics are coming from and the potential human health risks," Mallos says. Ahead, the foods that research has found to contain a measurable amount of microplastics: Tea Many commercial tea bags are made with polypropylene, a type of plastic used to seal the bags and maintain their shape. "When steeped in hot water, these bags can release microplastics into the tea. To avoid potential ingestion of microplastics, using loose leaf tea with a stainless steel or other non-plastic tea infuser is a safer and more sustainable alternative," Johnson says. Rice "Studies have shown that rice can contain relatively high levels of microplastics, likely due to contamination of soil and irrigation water," Johnson says. Rinsing rice thoroughly before cooking has been found to reduce its microplastic content by approximately 20–40%. Ultra-Processed Foods There's evidence that food processing is a likely source of microplastic contamination. Research has found that highly-processed protein products, such as chicken nuggets, tofu, and plant-based burgers, contain significantly more microplastics per gram than minimally processed products, such as wild Alaska pollock and raw chicken breast, Mallos says. Bottled Water When exposed to heat—such as being left in a hot car—or subjected to physical stress, like squeezing, plastic water bottles can release microplastics into the water. "Among various types, single-use plastic bottles tend to release the highest amounts of microplastics, followed by reusable plastic bottles," Johnson says. "In contrast, stainless steel and glass bottles do not degrade or leach microplastics, making them a safer and more sustainable choice for drinking water." Salt Believe it or not, even salt—a naturally occurring mineral—isn't safe from microplastics. Research has found that salt can contain large amounts of microplastics, reflecting the broader problem of environmental pollution. Himalayan pink salt contains the greatest amounts, followed by black salt and sea salt, Johnson says. Fruits & Vegetables "Due to widespread environmental contamination, fruits and vegetables can contain measurable amounts of microplastics," Johnson says. Some types of produce are more susceptible than others, like root vegetables (such as carrots, potatoes, and beets), because they absorb microplastics from contaminated soil and rainwater through their root systems. But all types of plants can absorb microplastics through their roots. Honey Even honey may be contaminated by microplastics, which is also a concern due to widespread environmental contamination, Johnson says. Plant-Based Foods In the study co-authored by Mallos, microplastic particles were found in tofu, plant-based nuggets, plant-based fish sticks, and plant-based ground beef. Fresh Seafood Microplastics in the ocean accumulate in fish and shellfish, ultimately impacting humans, who consume seafood containing these particles, Johnson says. Bottom-feeding species, such as clams, mussels, oysters, catfish, halibut, flounder, and cod, tend to have higher concentrations of microplastics compared to other marine organisms. Processed Seafood Processed seafood fares no better. Research shows breaded shrimp, pollock fish sticks, and shrimp also contain microplastics, Mallos says.
