Ancient meteorite minerals reveal a surprisingly strong magnetic field from the solar system’s first 200,000 years. About 4.6 billion years ago, before the Sun and planets existed in their familiar forms, the solar system was a vast cloud of gas and dust. Within a few million years, this “solar nebula” collapsed and flattened into a […]
4.6-Billion-Year-Old Meteorite Reveals a Surprisingly Strong Primordial Magnetic Field
Ancient meteorite minerals reveal a surprisingly strong magnetic field from the solar system’s first 200,000 years. About 4.6 billion years ago, before the Sun and planets existed in their familiar forms, the solar system was a vast cloud of gas and dust.

Black Hole Winds Are 100 Times More Powerful Than Astronomers Thought
Astronomers once thought winds generated by supermassive black holes affected only their host galaxies, but a recent study found that their energy can also reach surrounding galaxies. Winds from a supermassive black hole can carry energy far beyond the galaxy that contains it. New observations show that this influence can extend roughly 300,000 light-years and […]
Cutting Two Amino Acids Slowed Prostate Cancer in Mice
A newly identified link between amino acid metabolism and cholesterol production may help prostate tumors adapt to hormone therapy. Prostate cancer can find ways around treatments designed to deprive tumors of the hormones they need to grow. Weill Cornell Medicine investigators have now traced one possible route of resistance to amino acid metabolism, where a […]

“Cancer Melted Away”: Immunotherapy Delivers Striking Results in Bowel Cancer Trial
Pre-surgery immunotherapy kept a group of bowel cancer patients cancer-free for nearly three years, while personalized blood tests helped predict treatment response. Patients with a specific form of bowel cancer who received a short course of immunotherapy before surgery, rather than chemotherapy afterward, have remained cancer-free for nearly three years, according to updated findings from […]
A Strange Photosynthesis Trick Could Help Crops Survive a Hotter, Drier World
These new findings could help scientists adapt crops to dry environmental conditions in the future. Plants rely on sunlight to turn water and carbon dioxide into energy-rich sugars and oxygen through different forms of photosynthesis. Drought can make that process far more difficult. A research group led by Wolfram Weckwerth at the University of Vienna […]
This Tiny Organism Contracts 200 Times Faster Than You Can Blink – Scientists Finally Know How
Spirostomum uses a calcium-activated protein network to contract at remarkable speed without conventional muscle fibers. In less than five milliseconds, the aquatic single-celled organism Spirostomum ambiguum can shrink to one quarter of its body length, a movement hundreds of times faster than a human blink. Researchers have now traced that speed to an unusual calcium-activated […]
