Astronomers detect first ‘radio signal’ from interstellar comet 3I/ATLAS – but it wasn’t an alien
Astronomers have detected the first ever “radio signal” emanating from an interstellar comet, just as the comet 3I/ATLAS passed the halfway point on its one-way trip through the solar system. And while this may seem like ostensible evidence for the comet’s putative alien origins, it’s actually quite the opposite. 3I/ATLAS is the third known interstellar […]
Newly discovered toad skips the tadpole stage and gives birth to live ‘toads’
Scientists have identified three new species of toads that do not lay eggs, but live ‘toads’. All three species are part of the genus Nectophrynoides, also known as “tree toads,” a group known for giving birth to live toad babies that skip the tadpole stage. Previously thought to be a single species with large populations […]
Study reveals Japan’s prehistoric Jomon people had ‘little or no’ DNA from mysterious Denisovans
The Jomon people of prehistoric Japan had “little or no” Denisovan DNA, suggesting their ancestors may have had no contact with this now-extinct Eurasian human group, a new study reports. The discovery was part of a study of hundreds of ancient and modern genomes to determine when and where modern humans (Homo sapiens) interbred with […]
Leonids 2025: One of the last meteor showers of the year could peak this week with a bright ‘fireball’
The annual Leonid meteor shower will peak in the early morning hours of Monday (November 17). If you’re prepared to wake up early (or stay up late), you might be able to spot up to 15 meteors per hour in the moonless night sky. The Leonid meteor shower will be active from November 6th to […]
Scientists have developed the world’s first microwave brain microchip, a new type of processor that uses microwaves to perform calculations and requires very little electricity.
Scientists have developed a completely new type of microchip that uses microwaves instead of traditional digital circuits to perform its operations. The processor can run faster than traditional CPUs and is the world’s first fully functional microwave neural network (MNN) that can be mounted on a chip, scientists reported in a study published Aug. 14 […]
Physicists have discovered a new way to peer inside radioactive molecules, revealing strange phenomena in their nuclei
Physicists studied an unusual molecule to determine for the first time how magnetism is distributed within the nucleus of a radioactive atom. Generally speaking, the laws of nature do not change. If you throw a ball in Seattle or Tokyo, it will fall the same way. Physicists call this “symmetry” and use symmetry as a […]
History of Science: Russian mathematician quietly publishes paper – and solves one of mathematics’ most famous unsolved conjectures – November 11, 2002
simple facts Milestone: Solving the Poincaré conjecture When: November 11, 2002 Location: Saint Petersburg, Russia People: Grigori Perelman On a cold day in November, a man living a quiet life in Russia posted a paper on a public server. This book, published by “Grisha Perelman” and titled “The Ricci-style entropy formula and its geometric applications,” […]
2,300-year-old tools used for skull surgery unearthed at Celtic settlement in Poland
Archaeologists in Poland have discovered a rare iron tool used by the Celts to perform cranial surgery 2,300 years ago. The hand-held artifact was discovered at the Celtic site Wisa Góra in the Mazovia region of central-eastern Poland. “The manufacturing technique and precision of the ironwork is indicative of Celtic metallurgy,” Bartłomie Kaczynski, an archaeologist […]
Canada has lost its ‘measles elimination status’ – what this means
Canada has officially lost its measles-free status, meaning the highly contagious disease is once again consistently circulating in the country. The declaration was made by the international health organization Pan American Health Organization (PAHO), according to a statement from the Public Health Agency of Canada (PHAC) released on Monday (November 10). After reviewing recent epidemiological […]
New ‘near-interstellar’ comet incorrectly associated with 3I/ATLAS is scheduled to make its closest approach to Earth on Tuesday (November 11)
A never-before-seen comet that shares some minor similarities with the infamous interstellar object 3I/ATLAS is about to make its closest approach to our planet, just days after it was first spotted hurtling toward us. However, despite suggestions to the contrary, the newly discovered comet is almost certainly not related to modern interstellar visitors and originated […]
