Strange Rock Found on Mars

While exploring Mars the Perseverance rover spotted a striking rock with black and white striations, similar to Alpine granite. NASA scientists are intrigued, as this could signal a region with new insights about the planet.

The rock, named Freya Castle, stands out in Jezero Crater, a site mostly composed of bedrock and sedimentary layers. NASA’s Jet Propulsion Laboratory used the rover’s Mastcam-Z to take a closer look, suspecting it to be a metamorphic rock. If confirmed, it could offer valuable details about Mars’ volcanic history, suggesting the rock may have fallen into the crater from higher elevations. Scientists, including Klidaras, are now watching for more deposits of this type, which could help determine if the rocks were uplifted by the Jezero impact or transported by ancient volcanic activity.

Scientists Grow 1,000-Year-Old Seed

Forty years ago, an archaeological dig north of Jerusalem uncovered a well-preserved ancient seed, estimated to be over 1,000 years old. Recently planted, it has now grown into a mature tree, possibly a long-extinct species once used for medicinal purposes, and even mentioned in the Bible.

Initially, Israeli botanists, including Dr. Sarah Sallon of the Hadassah University Medical Center, couldn’t identify the seed’s species. Following a technique used to germinate ancient date palm pits, Dr. Sallon treated the seed with hormones, liquid fertilizer, and water, then planted it. Five weeks later, despite a millennium of environmental exposure, it sprouted. Now standing 10 feet tall, the tree has garnered global interest. Based on genetic analysis and expert consultation, Dr. Sallon’s team believes the tree might belong to the Commiphora genus, related to the myrrh tree. However, chemical tests showed no traces of the fragrant compounds found in Judean Balsam, a historic medicinal plant they initially suspected. Instead, the leaves contain guggulterols, a group of phytochemicals also found in Commiphora wightii, known for its potential cancer-fighting properties.

Ancient texts, including the Bible, refer to a medicinal balm called ‘tsori.’ Dr. Sallon’s team believes this is what they may have rediscovered, although confirmation will only come once the tree produces flowers or fruit. Dr. Louise Colville from the Royal Botanic Gardens, Kew, praised the achievement of reviving a seed this old, highlighting its significance for the potential of long-term seed preservation. “Seeing the potential for such extreme longevity gives us hope for seed banking and storage,” she commented.

Bolivia’s ‘cholitas escaladoras’

At 5,200 meters above sea level, two women sit at a stone table, surrounded by towering mountains. Huayna Potosí, a 6,088-meter peak in Bolivia’s Cordillera Real, looms ahead, its glacier shimmering in the afternoon sun. A narrow path winds across its icy surface, the goal for many climbers.

Cecilia Llusco, an Indigenous Aymara woman, nibbles on crackers with caramel spread and sips coca tea, her eyes fixed on the peak. “It’s not always about reaching the summit,” she reflects. “Sometimes it’s about enjoying the mountains and going as far as you can without suffering.” As clouds drift in, veiling all but the tallest peaks, Llusco shares her thoughts on life. “It’s not about getting to the top but enjoying the journey. The most important thing is to be happy.” At 39, Llusco is one of just 10 Indigenous female mountain guides in Bolivia. Her long black hair, adorned with wool in the colors of the Bolivian flag, is tied in two braids. She proudly wears a traditional Aymara skirt, called a pollera, along with a pink top and fleece. “I’ve never worn trousers to climb a mountain, and I never will. Our polleras don’t hold us back.”

Though Llusco has spent her life climbing Huayna Potosí, a defining moment came in December 2015, when she and 10 other women summited the peak. They called themselves the cholitas escaladoras—the climbing cholitas. Once used as a derogatory term for Indigenous women, “cholita” has been reclaimed by the group, symbolizing empowerment and pride in their heritage. Huayna Potosí is a place of deep connection for Llusco. “I feel free, like I’m escaping, and the mountain is calling me,” she says. As if on cue, a condor—the national bird of Bolivia—soars overhead. The mountain’s name means “young mountain” in Aymara, Llusco’s first language. It is a sacred site where climbers leave offerings of coca leaves and alcohol to ask for safe passage.

Tourists often attempt the three-day expedition to Huayna Potosí’s summit, known as one of the most accessible climbs above 6,000 meters. Still, altitude sickness frequently forces many to turn back. For six years, Llusco has led expeditions on Huayna Potosí and other Bolivian mountains, but her journey began long before that. At just eight years old, she started working in tourism alongside her father, a trekking guide. “I saw how much my father carried and wanted to help,” she recalls. “I loved meeting foreigners and learning about them.” Her dream of summiting Huayna Potosí was born on those early trips to the base camp.

Today, base camp is a simple shelter equipped with bunk beds, a small kitchen, and a dining room. As Llusco prepares vegetables for lunch, she also helps her group gear up with boots, helmets, crampons, and ice picks. Together, they hike to the glacier’s edge, where Llusco teaches them how to walk on ice. The best climbing months in Bolivia run from May to November, making Llusco’s work seasonal. Despite her years of experience, she still rents most of her gear, and her well-worn hiking boots are due for replacement—a costly challenge she faces as she continues her journey, both on the mountains and in life.

Adaptive Skin Fabric

We’ve all felt uncomfortable when our clothing doesn’t match the weather—like being too hot in a jacket or too cold without one. As a solution the researchers at the University of California, Irvine, have created a new type of fabric that can adjust its temperature to keep you comfortable in any weather. This innovative material lets air flow through easily, is simple to wash, and can be used in a variety of flexible clothing items. The inspiration for this fabric comes from squid skin, which can change color. Just like squid skin has layers that help it manipulate light, this new material works by reacting to the heat from your body. When your body temperature goes up, it releases heat as invisible infrared radiation. The fabric is designed to detect this heat and adjust itself to keep you comfortable.

Here’s how it works: the fabric is made of a special polymer covered with tiny copper pieces. When you stretch it, these pieces move apart, changing how the fabric interacts with heat. This means it can help keep you cool when it’s hot and warm when it’s cold. To make the fabric even better, the researchers ensured it could be washed, breathe well, and be easily added to other fabrics. They used a thin layer to make it washable, created holes for airflow, and attached it to a mesh to help it blend into different materials. This way, it can let air and moisture pass through, similar to regular cotton.

The researchers tested the fabric’s ability to regulate temperature and found that their improvements didn’t affect its heat-controlling abilities. According to study author Alon Gorodetsky, this advanced fabric has exciting potential for various clothing, especially for cold-weather gear like ski jackets, thermal socks, insulated gloves, and winter hats. He also mentioned that the techniques they used could be applied to other wearable technologies, making them washable and flexible too.
