Phys.org / Mega-Earth GJ 523b is 23 times as massive as our planet—but only 2.5 times as wide
It's nearly 170 million years old. It's more than 2.5 times the size of Earth. And it's the first exoplanet discovered and cataloged by researchers with the Wisconsin Center for Origins Research (WiCOR).
Medical Xpress / Does your immune system learn like AI?
Could AI hold the key to answering questions that have stumped doctors and scientists for decades? A recent study at Cold Spring Harbor Laboratory (CSHL) borrows concepts from machine learning to address an age-old riddle ...
Medical Xpress / Microglia reveal distinct disease patterns in genetic and sporadic frontotemporal dementia
In frontotemporal dementia, degeneration of neurons in the frontal and temporal lobes of the brain leads to impairments in behavior, speech and movement. However, it has become evident that other brain cells can also be involved ...
Phys.org / Immune cells have a 'sense of touch,' scientists discover
Scientists have long believed that tissue-resident memory T cells—which remain in tissues after an infection has cleared and respond rapidly if the threat returns—are shaped primarily by biochemical signals. A McGill University–led ...
Phys.org / Guangzhou crucibles provide earliest direct evidence of brass-making in East Asia
For centuries, scholars have read ancient documents describing the production of brass in 10th-century A.D. China. The problem was that the earliest physical evidence of brass production would be found nearly 600 years later, ...

Researchers from the German Cancer Research Center (DKFZ) and the HI-STEM Stem Cell Institute have identified a previously unknown mechanism by which a particularly aggressive form of colon cancer evades the immune system.
Phys.org / New photonic crystal method improves single-photon sources for quantum networks
Quantum communication promises many advantages over today's standard technologies, including absolutely secure transmission of large amounts of data. However, it requires single photons—and generating them is very difficult. ...
Phys.org / As Europe's rivers recede, shippers scramble to limit damage
Exceptionally low river levels in a Europe hit hard by drought and record heat have plunged transporters into turmoil this summer, driving up costs that everyday consumers could end up bearing.
