Unlocking Earth’s Secret Factory for Cleaner, Greener Fertilizer

by Cell Press / 21min

Discover a new, eco-friendly method of synthesizing ammonia using Earth’s natural geological processes, potentially transforming fertilizer production and reducing the chemical industry’s carbon footprint. Instead of using energy-intensive reactors to produce ammonia, scientists are exploring a more natural approach by tapping into Earth’s underground heat and pressure. A recent proof-of-concept

Breakthrough Single-Dose Drug Wipes Out Breast Tumors in Mice Without Side Effects

Single-dose drug eradicates breast cancer

•

by American Chemical Society / 21min

A revolutionary new treatment for breast cancer has shown the ability to eliminate small breast tumors and significantly shrink large ones in mice with a single dose. This innovative approach targets estrogen receptor-positive cancers more selectively, aiming to reduce side effects and improve patient outcomes. New Breast Cancer Treatment Research Despite advances in treatment, breast [...]

MIT Students Revolutionize Coffee Brewing With Cutting-Edge Science

by Jason Sparapani, MIT Department of Materials Science and Engineering / 2h

Undergraduate MIT class blends science, hands-on experimentation, and a love for coffee to fuel curiosity. In a pioneering MIT course blending chemistry lectures with hands-on brewing, students like Elaine Jutamulia and Omar Orozco experiment with additives to enhance coffee flavors, employing advanced instruments like infrared spectrometers to dissect the impact on coffee’s chemical profile. Cof

Revolutionizing Clean Energy? Yale Scientists Discover How Bacteria “Breathe” Minerals

by Yale University / 2h

Yale researchers uncovered the molecular machinery behind nanowire assembly in microbes, enabling advances in electricity production, pollution mitigation, and methane reduction. Almost all living organisms breathe oxygen to remove excess electrons generated during the conversion of nutrients into energy. However, many microbes that play a crucial role in mitigating pollution and climate change l

Antarctica’s Amery Ice Shelf Is Melting Faster Than Ever

NASA reveals melting Antarctic ice

•

by Kathryn Hansen, NASA Earth Observatory / 2h

Satellite data from early 2025 revealed extensive melting at Antarctica’s Amery Ice Shelf, highlighting its vulnerability. As a natural barrier against ice flow, its weakening could accelerate sea level rise. By late 2024, Antarctica experienced significant melting along its coastal regions, even though the melt season was less than halfway through. As 2025 began, meltwater [...]

Secrets of Andromeda Revealed in Hubble’s Epic 2.5 Billion Pixel Image

Hubble reveals Andromeda's hidden history

•

by Space Telescope Science Institute / 5h

Panorama of Nearest Galaxy Unveils Hundreds of Millions of Stars On a crisp, clear autumn night, you can see the most distant object visible to the naked eye — the stunning Andromeda Galaxy, our Milky Way’s closest major neighbor. Located just northeast of the Great Square of Pegasus, it appears as a faint, spindle-shaped patch [...]

Wireless Nanoparticle-Based System Found To Reverse Parkinson’s Disease

Gold nanoparticles reverse Parkinson's damage

•

by Chinese Academy of Sciences / 6h

A novel wireless photothermal DBS nanosystem uses nanoparticles to target and restore damaged neurons in Parkinson’s disease, offering a non-invasive, precise, and safe alternative to traditional DBS. Parkinson’s disease (PD) is the second most prevalent neurodegenerative disorder, primarily marked by motor dysfunction. The pathological hallmark of PD is the abnormal aggregation of α-synuclein (α

Astronauts Gear Up for a High-Stakes Spacewalk to Hunt Microbes in Microgravity

by NASA / 6h

On January 21, the Expedition 72 crew spent the day getting ready for their second spacewalk of 2025 outside the International Space Station (ISS). This mission focuses on removing old communications equipment and investigating the presence of potential microbes. Meanwhile, the crew continued their ongoing scientific research, which included studying advanced space navigation, analyzing microbial

New Research Uncovers Long-Lived DNA Damage Linked to Cancer

DNA damage persists causing mutations

•

by Wellcome Sanger Institute / 8h

In a groundbreaking shift in our understanding of mutations, researchers have discovered types of DNA damage in healthy cells that can remain unrepaired for years. While most types of DNA damage are repaired by the body’s natural DNA repair mechanisms, some forms of damage can evade these processes and persist for years, according to new [...]

NASA’s Eyes in the Sky Reveal LA’s Hidden Air Pollution Crisis

by Adam Voiland, NASA Earth Observatory / 9h

NASA’s TEMPO sensor observed significant changes in air pollution in Los Angeles in early January 2025. Initially monitoring routine emissions, it soon tracked intense NO2 plumes from two major fires exacerbated by Santa Ana winds, showcasing the sensor’s critical role in environmental monitoring. On January 6, 2025, as Los Angeles went about its daily routine, [...]
