A Rover Has Spotted Possible Evidence of Liquid Water on Mars
China’s Zhurong rover has discovered evidence of liquid water on present-day Mars, which is a significant breakthrough in the search for habitable environments on the Red Planet. The team of researchers analyzed the makeup of the dunes in the immediate vicinity of the rover’s landing site, using three of its instruments, and found that the dunes were rich in hydrated sulfates and possibly contain chlorides. The findings are important for understanding the evolutionary history of the Martian climate and providing key clues for the future search for life.
This Robot Will Collect Seaweed to Help Absorb Carbon Into the Ocean Floor
Seaweed Generation, a robotics company, is creating manta ray-shaped robots called AlgaRay, designed to combat the growing issue of sargassum seaweed washing up on Mexican beaches. This seaweed absorbs substantial amounts of CO2, and the robots collect it and deposit it in deep ocean waters, where it cannot photosynthesize and eventually dies, trapping the carbon on the seafloor. Seaweed Generation's vision includes deploying a fleet of these robots to manage sargassum in the seas, potentially removing billions of tons of carbon dioxide annually.

A NASA Spacecraft is Getting an Extended Lifeline for an Outer Solar System Mission
NASA has decided to extend its New Horizons mission, allowing the spacecraft to continue exploring the outer reaches of the solar system until it exits the Kuiper Belt, expected around 2028. Originally slated to conclude operations by the end of 2024, New Horizons will now focus on collecting heliophysics data while also conducting a close flyby of an object in the Kuiper Belt. The decision to extend the mission was met with enthusiasm, as New Horizons continues to provide valuable insights into the solar system's outer regions and its origins.
A 200-Year-Old Painting Was Just Discovered to be an Original by an Esteemed Artist
A 200-year-old painting, initially believed to be a copy, has been identified as an original work by renowned 18th-century artist Rosalba Carriera, known as the "Queen of Pastel Painting."

The discovery of a hidden slip of paper known as a "Santini," containing prayers and blessings for safe passage, in the painting's frame confirmed its authenticity and is a valuable find for art enthusiasts.
The World Health Organization Just Approved a Second Vaccine for Malaria
The World Health Organization (WHO) has approved a second malaria vaccine, offering countries a potentially more accessible and cost-effective option than the initial vaccine. The new vaccine, developed by the University of Oxford, could be a significant tool in the fight against malaria, especially in regions where the disease is endemic. While it may not replace existing prevention methods like bed nets and insecticides, its increased availability could significantly reduce severe illness and deaths caused by malaria in the coming years.
A New Study Shows Walking This Much More a Day Can Help Lower Your Blood Pressure
A new study has provided an uplifting reason to make walking a daily habit, showing that taking an additional 3,000 steps per day can significantly reduce blood pressure in older adults with hypertension. High blood pressure is a common health concern, and this research suggests that incorporating more walking into daily routines can be an effective way to manage it. The findings suggest that walking can be as effective as anti-hypertensive medications in managing blood pressure, emphasizing the importance of physical activity for overall well-being.
Meet the Kenyan Entrepreneur Turning Plastic Waste Into Fuel
In a remarkable initiative, Kenyan entrepreneur James Muritu is tackling plastic waste by transforming it into a valuable resource: fuel. Through a process called pyrolysis, plastic waste is heated at high temperatures in the absence of oxygen, converting it back into oil or hydrocarbon liquid. Muritu's innovative solution not only addresses the pressing issue of plastic waste but also provides an eco-friendly alternative fuel source for cars and engines, offering hope in the battle against plastic pollution and climate change.
