Archaeologists in Russia have made an extraordinary discovery. They have identified a spear carved from bone that’s about 70,000 to 80,000 years old. This is the oldest spear ever found in Europe— but this isn’t the most interesting part. What makes this ancient weapon truly special is that it was made by Neanderthals, our close ancient relatives. Until now, scientists believed that only modern humans (Homo sapiens) had the ability to make complex bone tools.

How long does a free neutron really live before it decays? This simple question has annoyed physicists for decades. Moreover, when they searched for an answer, they found not one but two confusing solutions that further deepened this mystery. The solutions come from two experimental methods, known as the beam and bottle techniques. The results from these methods differ by about 10 seconds.

A concept image of quark-gluon plasma. Naeblys/iStockEverything you see around and is there in outer space originated from superhot quark-gluon plasma. Moments after the Big Bang, the universe was unimaginably hot, dense, and filled with freely moving quarks and gluons. This exotic state, known as quark-gluon plasma, lasted for just a few microseconds. Then, as the universe cooled to around 20 trillion degrees Kelvin, these particles began to freeze into the matter we know today.

Imagine if we could make chemical reactions thousands of times faster just by using a magnetic field. That’s exactly what researchers at Tohoku University in Japan have achieved. In their new study, they show that applying an external magnetic field can precisely tune the spin state of single-atom catalysts (SACs) and boost their performance. This discovery could reshape how we produce ammonia for fertilizers and treat polluted water, all while reducing energy use and environmental impact.

A man standing in front of a blackboard covered in math problems. (Representational image)Max Fischer/PexelsFor over a decade, a mysterious mathematical theory has perplexed mathematicians worldwide. Known as the Inter-universal Teichmüller Theory (IUT), it is so complex and hard to understand that even seasoned mathematicians described it as the “alien’s language.”While there are thousands of mathematicians worldwide, to this date, only 20 have managed to understand IUT to some extent.

This Polish radio station fired all its journalists and replaced them with AI hosts — and people are furious. https://t.co/r729mddLVC

Can we eliminate cement from construction? The answer is yes. A new approach called impact printing offers all the benefits of 3D printing but uses Earth-based material to build structures. https://t.co/fRYiqnB9Hk
