▼ + stars: | 2024-10-31 | by ( Ashley Strickland | ) edition.cnn.com time to read: +9 min

The Mary Rose was one of the largest warships of the Tudor navy during King Henry VIII’s reign until it sank on July 19, 1545, during a battle against the French. The Mary Rose was one of them, and the flagship became the king’s favorite. The hull of the Mary Rose, supported by a steel cradle attached to a lifting frame, was raised on October 11, 1982. The research team used Raman spectroscopy, a nondestructive method that preserves valuable samples, to study the bones, Shankland said. “Investigating the impact of this on the spine would further our understanding of bone chemistry changes with age, but also with stress from activity.”

Good balance, strength, and a sturdy gait keep us mobile and independent as we age. There are other quick, simple tests you can do at home to help you assess how fit you are for your age. AdvertisementHow long a person can stand on one leg could reflect how well they're aging, according to a study. "If you have poor balance, you're at risk of falling, whether or not you're moving. It's typically used on older adults to test leg strength and endurance, but there's some evidence that it's also useful for measuring athletic performance in younger adults.

Balance is important for injury prevention, and those who are unable to balance on one leg for more than five seconds could be at risk of falling more, Kaufman said. If someone is unable to stand on one leg for more than five seconds, Kaufman recommends making an appointment with a physician. “If we practice standing on one leg, we’ll get better at standing on one leg. That’s great but it’s not going to solve all balance problems and fall risk that happen with aging. … People should work on all aspects of balance — static, dynamic and overall strength, including but not limited to standing on one leg.”To improve your balance, Lubetzky recommends fitness or balance classes, such as yoga classes, that usually aim for about 30 or 60 seconds of balance on each leg.

CNN —For the first time, scientists have found evidence that marine mammals could be inhaling microplastics, according to new research that detected the potentially harmful particles in the breath of bottlenose dolphins off the coasts of Louisiana and Florida. Previous research has discovered the tiny particles present in marine mammals’ tissues from exposure through consumption and then movement from the digestive tract into other organs. “We found that dolphins may be breathing in microplastics, even if they live in rural areas away from high levels of human activity. The researchers are unsure how inhalation of microplastics will affect dolphins, but they suspect it could have an impact on the creatures’ lung health, according to the study. The study team held up petri dishes to the mammals’ blowhole, through which dolphins inhale and exhale.

ISER Caribe executive director Stacey Williams dives underwater to clip lines of astroturf-like material where baby sea urchins are growing. The group is working to restore 5 acres of coral reef in Puerto Rico by planting fragments across six reefs and returning long-spined sea urchins to the ecosystem. Then, once the urchins reach young adult size, the researchers place them in a coral reef in need of extra support. Manzello said scientists used to think coral had a longer runway — perhaps until 2040 or 2050 — before conditions became so grim.

☆ Egypt’s first pyramid constructed using a hydraulic lift, study says
▼ + stars: | 2024-08-05 | by ( Taylor Nicioli | ) edition.cnn.com time to read: +11 min

Now, a team of engineers and geologists brings a new theory to the table — a hydraulic lift device that would have floated the heavy stones up through the middle of Egypt’s oldest pyramid using stored water. Water from ancient streams flowed into a system of trenches and tunnels that surrounded the Step Pyramid, according to the study team. The shaft within the Step Pyramid is connected to a 200-meter-long (656-foot-long) underground tunnel that connects to another vertical shaft outside the pyramid. Conversely, a moderate-sized hydraulic lift can raise 50 to 100 tons. “It doesn’t mean (the hydraulic lift device) wasn’t used,” she added.

To understand how hens visibly express emotion, researchers spent four weeks on a French farm observing 17 hens of two different breeds, Bertin said, filming their routine behaviors and their reactions to different stimuli. Researchers observed 17 hens on a French farm. INRAE Arnould BertinTo make their more general conclusions, researchers extracted images from every two seconds of film and selected ones that featured the hen in profile to best study them. Although researchers weren’t able to explain the mechanism by which hens blush in this study, they concluded that the cheeks and ear lobes were more revealing of the birds’ emotions than their comb or wattles. Building on the results of this study, Bertin hopes to investigate whether these displays of emotion are linked to the hens’ social interactions, as well the implications for animal welfare.

Instead, the team determined that the shape of the cut marks was consistent with those made by stone tools. “The cut marks were not randomly distributed but focused on those skeletal elements that harbored large muscle packs like the pelvis and the tail,” he said. A detailed examination of cut marks on the fossils revealed they were made by stone tools in a deliberate sequence. Along with three perforated giant sloth bones found in Brazil that archaeologists believe humans used as pendants 25,000 to 27,000 years ago, the butchered armadillo bones suggest that humans were in South America a surprisingly long time ago. “Until recently, the traditional model indicated that humans entered the continent 16,000 calendar years ago,” he said.

Tyrian purple was a highly prized pigment developed in the Bronze Age, and it retained its status into the late medieval period. Several pottery fragments had residue of Tyrian purple pigment, the research team revealed. The well-preserved pigment could be used to dye textiles today, lead study author Dr. Lydia Berger said. Once collected, the snails had to be kept alive until the purple dye makers were ready to crush them and extract the mollusk’s mucus glands. The process came with a fishy odor, one that the researchers recognized when they came across the purple pigment residue in the recent excavation at Kolonna, she added.

While a growing body of research shows decreases in many insect populations, it has been hard for scientists to disentangle the possible causes. Are insects suffering from habitat loss as natural areas are plowed and paved? The latest insight comes from a study on butterflies in the Midwest, published on Thursday in the journal PLOS ONE. Especially detrimental, the researchers found, was a class of widely used insecticides called neonicotinoids that are absorbed into the tissues of plants. “It’s a story about unintended consequences,” said Scott Swinton, a professor of agricultural economics at Michigan State University and one of the study’s authors.

“It’s often helpful to think about episodic memory as remembering, whereas semantic memory is just knowing,” he said. To find out whether Eurasian jays are capable of "mental time travel," researchers worked with birds trained to find food hidden under cups. “The idea is that with human episodic memory, we remember details of events that, at the time, weren’t necessarily relevant to anything. This aspect of episodic memory is sometimes referred to as “mental time travel.”To find out whether Eurasian jays are capable of mental time travel, the researchers worked with birds that had been trained to find food hidden under cups. “The big disease of memory is Alzheimer’s disease, and of course, the most debilitating aspect of Alzheimer’s disease is a profound loss of episodic memory,” Crystal said.

However, vegetarian diets limiting but not completely excluding certain types of meat and fish, such as pesco- or pollo-vegetarian diets, were excluded, he said. “Strictly vegan diets can be deficient in vitamin B12,” Gardner said. “Iron is another nutrient that is harder to get from a fully vegan diet,” Gardner added.

But for nearly a billion people in the developing world, reading glasses are a luxury that many cannot afford. Uncorrected presbyopia, not surprisingly, makes it harder for breadwinners to support their families. That’s the conclusion of a new study which found that garment workers, artisans and tailors in Bangladesh who were provided with free reading glasses experienced a 33 percent increase in income compared to those who were not given glasses. Half of the participants — a mix of tea pickers, weavers and seamstresses between 35 and 65 — were randomly chosen to receive a free pair of reading glasses. The others were not given glasses.

More dire long-term consequences may also be at play, according to new research on the associations between work patterns in young adulthood and health outcomes later in life. Multiple studies have shown how irregular work hours can harm overall health and social life, but the new paper views the relationship through a “life-course” approach, observing how work patterns affect health throughout adulthood instead of one point in time. Despite the challenges of today’s work schedules, health experts say there are strategies people can use to mitigate the negative impacts. Additionally, still having some kind of routine or schedule around that shift can make it easier to fit in those health-promoting activities — especially sleep, Yao added. And past research has found that refraining from eating late at night counteracts the negative effects of shift work on health, he added.

☆ Researchers think they have the key to why tardigrades can survive almost anything
▼ + stars: | 2024-02-05 | by ( Jenna Schnuer | ) edition.cnn.com time to read: +6 min

CNN —Tardigrades, also known as water bears, commonly survive in some of Earth’s most challenging environments. Under stress in extreme cold or other harsh environmental conditions, tardigrades’ bodies produce unstable free radicals of oxygen and an unpaired electron, aka a reactive oxygen species that can wreak havoc on the body’s proteins and DNA if they overaccumulate. The survival mechanism kicks off when cysteines, one of the amino acids that forms proteins in the body, come into contact with these oxygen free radicals and becomes oxidized, the researchers found. The free radicals become, so to speak, the hammer used to smash the glass on a fire alarm. “We came up with this idea (that) maybe it’s those species that are actually signaling to the tardigrades to enter their tun state,” she said.
