Mars’ Olympus Mons May Awaken!
A new study of Martian gravity conducted by an international team of astronomers has revealed a large area of weaker gravity beneath the Tharsis Plateau, where Olympus Mons is located.
This is most likely a giant magmatic plume extending about 1,600 km—essentially, a flow of lava slowly rising from the planet’s interior.
In the future, this process may well lead to an eruption of the largest volcano in the Solar System, dormant for millions of years. Moreover, three neighboring smaller volcanoes might also become active.
The summit of Olympus Mons stands at an altitude of 22 km, effectively beyond the Martian atmosphere. Therefore, it would eject smoke and lava into space. However, according to scientists’ forecasts, the volcano itself would be completely destroyed by this eruption, should it occur.
Robo-Dog Conquers Vertical Ladders
A method has been developed to train a quadruped robot to climb ladders. By combining hook-like grippers with reinforcement learning algorithms, researchers achieved a 90% success rate on slopes ranging from 70° to 90°. The climbing speed has been increased by 232 times compared to previous models.
The robot adapts to different ladder parameters and remains stable against external disturbances. Remarkably, the system requires no additional tuning when transitioning from simulation to a real robot. The climbing gait resembles that of humans: the hind legs generate lifting force while the front legs provide stability.
Pros: No need to walk it.
Cons: Can't hide, can't escape.

Scientists Successfully Grow Tree from a 1,000-Year-Old Seed
In an extraordinary feat of botanical science, researchers have cultivated a tree from a seed that dates back to between 993 and 1202 AD. The seed was discovered in the 1980s in a cave within the Judean Desert. After extensive radiocarbon dating, the team confirmed its ancient origins.
The sapling, named “Shiba,” belongs to the rare Commiphora genus, which is still found across Africa, Madagascar, and the Arabian Peninsula. DNA analysis suggests a potential connection to the fabled “Balm of Gilead,” a plant referenced in biblical texts for its medicinal properties.
It took 14 years for scientists to nurture the tree to its current height of three meters. However, it has not yet flowered or borne fruit, making it challenging to compare with contemporary species. Researchers speculate that its current environment may not be conducive to flowering and reproduction.
Historically, the resin from this tree was highly valued for its therapeutic qualities, being used in perfumes, medicines, and antidotes. The biblical “tzori,” a balm derived from this resin, was prized throughout the Roman Empire for its medicinal applications. Experts believe that in ancient times, this species might have been grafted onto the famed Judean balsam tree to enhance its properties.
This remarkable achievement not only sheds light on ancient horticultural practices but also offers a glimpse into the botanical diversity of biblical times.

Breaking news: Earth is habitable! A sensational discovery by the European spacecraft JUICE.
But seriously, while the probe was performing a gravity assist maneuver before its long journey to Jupiter, it analyzed our planet’s atmosphere. The Submillimeter Wave Instrument (SWI) detected elements essential for life: oxygen, hydrogen, nitrogen, carbon, phosphorus, sulfur, as well as ozone, carbon dioxide, and water. Meanwhile, the Moon and Jupiter Imaging Spectrometer (MAJIS) captured infrared images of Earth’s surface, resulting in detailed temperature maps.
European scientists conducted this work not just for fun but to calibrate the instruments and ensure they are functioning properly.
The GIF shows how SWI scans Earth’s atmosphere.
Safe travels to Jupiter, JUICE!

A group of scientists from China analyzed the composition of soil samples brought back from the far side of the Moon, according to China Central Television.
The lunar soil samples delivered by the “Chang’e-6” mission primarily consist of basalt, breccia, cementite, light-colored rocks, and glassy material. Basalt fragments make up 30% to 40% of the total sample volume. The minerals are mainly pyroxene, plagioclase, and ilmenite, with very little olivine present.
The mineralogical analysis revealed that the primary phase composition of the lunar soil samples is as follows: plagioclase (32.6%), pyroxene (33.3%), and glass (29.4%), with the glass content near the lower limit of samples retrieved during the Apollo missions.

Scientists in the U.S. have made biological tissues of live mice transparent using a solution of the dye tartrazine, which absorbs light. The dye was applied to the shaved scalp of the mouse, allowing researchers to visualize brain blood vessels with laser speckle contrast imaging. The solution also made the mouse's abdomen transparent, enabling direct observation of internal organs like the liver, intestines, and bladder. Remarkably, the effect is reversible by simply washing off the solution with water.

What still sets Telegram apart from other media outlets?
Well, consider this: Google has a division called the Threat Analysis Group (TAG), which combats disinformation by identifying and blocking channels and advertising campaigns that support the "wrong" policies and criticize the "right" ones. Their focus is on geopolitical content related to Ukraine, Western institutions, and U.S. foreign policy.
In their reports, the division details how it takes down pro-Russian YouTubers—not just Russian-speaking ones—because there's no need to create a positive image of Russia here.
From the perspective of a transnational corporation, it's only natural that China and Iran get banned. You can't support Azerbaijan and criticize Armenia. You can't support President Shavkat Mirziyoyev in the Uzbek language. You can't express an original opinion from Togo or Burkina Faso. In Poland, speaking Polish before elections, you can't say anything against the European Union. In Mexico, you can't support the Morena party and Senator Ricardo Monreal. In Vietnamese, you can't support the government of Vietnam and its policies. In Turkish, you can't support Palestine and criticize Israel.

By 2050, Nearly 40% of Adolescents Could Suffer from Myopia
A recent systematic review and meta-analysis by Chinese scientists has revealed a startling trend: between 1990 and 2023, the prevalence of myopia (nearsightedness) among children and adolescents surged from 24.32% to 35.81%. If this trajectory continues, by 2050, nearly 40% of adolescents worldwide—approximately 750 million individuals—could be affected by myopia.
Myopia typically develops in early childhood and often worsens as individuals progress into adolescence and adulthood. Younger schoolchildren are particularly susceptible to risk factors, and this vulnerability is even more pronounced in preschool-aged children due to critical periods of visual development.
The study's conclusions are drawn from data spanning 276 studies, encompassing over 5 million children and adolescents across 50 countries in Europe, the Americas, Asia, Africa, and Oceania. Collectively, these studies recorded nearly 2 million cases of myopia.
One of the primary factors contributing to this rise, according to the researchers, is the increasing amount of time children spend in front of screens—be it computers, tablets, or smartphones. The recent COVID-19 pandemic may have further exacerbated the situation by necessitating more screen time for remote learning and reduced outdoor activities.
Implications: This growing public health concern underscores the need for proactive measures. Encouraging outdoor activities, limiting screen time, and regular eye check-ups could be vital steps in mitigating the risk of myopia in younger populations.

Scientists from the Ocean University of China have reconstructed Earth’s plate tectonics over the past 1.8 billion years.
They’ve condensed this vast timeline into an animation just one minute long! The animation showcases the movement of continents over nearly half of our planet’s history.
Around 200 million years ago, when dinosaurs roamed the Earth, Gondwana merged with North America, Europe, and Northern Asia to form the supercontinent Pangaea. Both Pangaea and Gondwana were composed of even older tectonic plates. The reconstruction then reveals the even earlier supercontinent Rodinia, which formed from the ancient supercontinent Nuna around 1.35 billion years ago.

A clear illustration: how the brain heals the heart. Essentially, this image represents a prototype of a new kind of medicine.
We see the hearts of mice 15 days after a heart attack. The ones on the right are significantly better preserved — they have more cardiac tissue and less fibrotic tissue. What’s the reason? The mice on the right had daily stimulation of a specific brain area: dopamine neurons in the ventral tegmental area (VTA). This reduced inflammation and enhanced healing in the heart. It also affected the liver, which began producing more of a protein that helps form new blood vessels in the damaged heart tissue. No direct treatment was applied to the heart itself; only brain cells were activated.

Scientists have made progress in uniting general relativity and quantum physics, two theories that traditionally clash. A new approach considers gravity as an "emergent" phenomenon, arising from quantum interactions rather than a fundamental force. This breakthrough could potentially lead to a unified theory of quantum gravity, bridging the gap between our understanding of the cosmos at both massive and tiny scales.

Termites of the species *Neocapritermes taracua* from French Guiana have a unique defense mechanism where they "explode" to protect their colony. These termites carry toxic "backpacks" containing the BP76 enzyme, which remains in a stable form until mixed with secretions during a threat. The enzyme's copper-based structure and sugar molecules keep it stable until needed. Once triggered, the explosive reaction releases a deadly toxin, immobilizing or killing attackers, though the termite itself perishes in the process.
