ASTRONOMERS IDENTIFY ASTEROID 2024 YR4 AS EARTH THREAT

Astronomers have identified asteroid 2024 YR4 as the most likely sizable space rock to impact Earth, with a 3.1% chance of hitting on December 22, 2032. First detected in December, the asteroid is between 130 and 300 feet long, smaller than Apophis but still capable of causing significant damage depending on where it strikes. If it enters Earth’s atmosphere, a direct hit on a city could cause destruction, while an airburst could result in injuries and widespread damage. The asteroid’s composition and size influence its impact, with stony asteroids more likely to explode in the atmosphere, like the Tunguska event of 1908. A larger 300-foot asteroid could potentially reach the surface, creating a massive explosion and a crater up to two-thirds of a mile across. While the odds of impact remain low, scientists are taking the threat seriously and are closely monitoring the asteroid’s trajectory. (New York Times)

TEXAS MEASLES OUTBREAK SPREADS TO FIVE COUNTIES

The Texas Department of State Health Services (TDSHS) reported an additional 10 measles cases, bringing the outbreak total to 58 since early February. Gaines County remains the epicenter with 45 cases, while Terry County has seen six more cases and Lubbock County has its first. The outbreak now spans five counties in west-central Texas near the New Mexico border. Of the hospitalized patients, 13 remain in care, with four having been vaccinated. Roughly half of the cases involve school-age children. The highly contagious nature of measles means further cases are likely, particularly in Gaines County and surrounding areas. Meanwhile, neighboring New Mexico’s Lea County is also investigating a potential link to the Texas outbreak. Health officials across multiple states, including Alabama, have issued warnings, emphasizing the contagiousness of measles and urging parents to ensure children are up to date on vaccinations.

SPANISH CHILD FIRST TO OVERCOME WISKOTT-ALDRICH SYNDROME

Jesús Lunar and Cristina López discovered their son Javier had Wiskott-Aldrich syndrome, a rare genetic disease affecting the immune system. Initially devastated by the diagnosis, they found hope in a groundbreaking gene therapy trial, which made Javier the first child in Spain to overcome the syndrome. The therapy replaced the defective gene with a healthy one, overcoming the need for a bone marrow transplant, which was not an option due to the lack of a compatible donor. The Telethon Foundation in Italy took over the therapy’s development after it faced potential cancellation, saving the treatment and pushing it towards approval by the European Medicines Agency. This innovative approach highlights the challenge of bringing rare disease treatments to market, often hindered by high costs and limited commercial interest. Javier’s case has sparked a revolution in both medical science and the pharmaceutical market, offering new hope for other children with similar conditions. (El Pais)

EUROPEAN LIFE EXPECTANCY GROWTH SLOWS WITH ENGLAND DECLINE

Life expectancy growth across Europe is slowing, with England experiencing the sharpest decline. Research published in *The Lancet Public Health* revealed that from 2011 to 2019, life expectancy growth dropped from an average of 0.23 years per year (1990-2011) to 0.15 years. England’s decline was the largest, falling from 0.25 to 0.07 years. This slowdown is linked to rising obesity, poor diets, and physical inactivity, with cardiovascular disease and cancer playing significant roles. The COVID-19 pandemic further exacerbated these trends, with most countries seeing a drop in life expectancy from 2019 to 2021. However, countries like Norway, Iceland, Sweden, Denmark, and Belgium fared better due to stronger health policies targeting heart disease and cancer prevention. Experts emphasize the need for better government policies to address obesity and promote physical activity. The UK’s NHS is working on a 10-year health plan focused on prevention to improve life expectancy. (The Guardian)

MANILA RESIDENTS EXCHANGE MOSQUITOES FOR CASH TO FIGHT DENGUE

In a central Manila neighborhood, residents lined up on February 19 to exchange mosquitoes for cash as part of an initiative aimed at curbing the spread of dengue. For every five mosquitoes, dead or alive, participants received one peso (US$0.05). This project, started by village captain Carlito Cernal, is part of a local effort to raise awareness about the disease, alongside clean-up initiatives. However, health experts were skeptical about its effectiveness, suggesting that basic preventive measures, such as eliminating stagnant water and using insect repellent, are more crucial. The Philippines has seen a sharp rise in dengue cases, with over 28,200 recorded by February 1, a 40% increase from the previous year. Despite concerns that some might even breed mosquitoes for the reward, many residents, like Rachel Estoque, participated to help prevent the disease, driven by personal experiences with dengue’s hardships.

DEEPSEEK AI STARTUP GAINS GLOBAL ATTENTION WITH CHATBOT TECHNOLOGY

DeepSeek, an AI startup founded by Liang Wenfeng, has rapidly gained global attention for its chatbot technology. Despite its prominence, the team behind it remains largely unknown outside of China. Liang, often compared to Sam Altman in Western media, maintains a low public profile, while his team consists of fewer than 140 people, with many coming from top Chinese universities like Tsinghua and Peking University. Liang’s journey began in his youth, excelling in mathematics and eventually founding High-Flyer Asset Management, a quantitative hedge fund, in 2015. High-Flyer’s success helped fund DeepSeek, which was spun off in 2023 with a focus on artificial general intelligence (AGI). The company hires young, academically accomplished engineers, with many team members returning to China from American firms like Nvidia and Microsoft. DeepSeek’s leadership values creativity, foundational skills, and passion, offering attractive salaries and a bottom-up management style to attract top AI talent. (CNBC)

PALEONTOLOGISTS DISCOVER COMPLETE SKULL OF BASTETODON IN EGYPT

Paleontologists have discovered a nearly complete skull of an ancient carnivore called Bastetodon syrtos in Egypt’s Fayum Depression, shedding light on the hyaenodont family. These creatures, once apex predators, went extinct about 25 million years ago. The species, named after the Egyptian goddess Bastet due to its catlike features, had a shorter snout and sharp teeth, giving it a powerful bite. The discovery, dating back to the early Oligocene Epoch, is one of the most complete hyaenodont skulls ever found in Africa. Researchers believe Bastetodon was the dominant predator in the ancient Egyptian forest, preying on primates and early hippos. The skull provides rare insights into the animal’s muscle structure, brain size, and sensory capabilities. This finding contributes to understanding the evolutionary shift from hyaenodonts to modern carnivores like dogs and cats, offering clues about the factors—such as climate change and competition—that led to their extinction.

JAPAN ADVANCES SPACE FARMING TECHNIQUES FOR LUNAR SETTLEMENTS

At Chiba University’s Research Center for Space Agriculture and Horticulture, researchers are advancing “space farming” techniques that could one day support lunar settlements. The center focuses on cultivating crops like strawberries, tomatoes, and lettuce using soilless cultivation methods in controlled environments. Their goal is to grow food efficiently in confined spaces, addressing challenges such as the moon’s extreme temperatures and lack of atmosphere. Established in 2023, the center is the only horticulture faculty at a national university in Japan, applying its expertise in crop improvement to space farming. With the Artemis program aiming to send humans to the moon, researchers plan to establish a space farm on the lunar surface by the 2040s. Their work is not just for space but also has applications for Earth, including sustainable farming practices and circular food production systems that reduce waste. Collaboration with global research institutions is key to realizing these goals. (Asahi Shinbun)
