Human brain tissue successfully implanted in rats A new study shows that balls of human brain neurons can be implanted and integrated into the brains of rats. Researchers reveal that lab-grown “human brain organoids” integrated into the rats’ brains within three months, which may pave the way for repairing injured human brains in the future […]

At the end of 2022, researchers at Lawrence Livermore National Laboratory announced they had observed a net energy gain through nuclear fusion for the very first time. This monumental milestone toward fusion energy represents a huge leap forward in powering our homes and businesses with the carbon-neutral energy source. But converting this scientific achievement into […]

Antidepressants may create antibiotic resistance Antidepressants may cause bacteria to become resistant to antibiotics, according to a study exposing the bacterium E. coli to five common antidepressants. Researchers need to further explore the effect, which was found in Petri dishes, to study whether these antidepressants can cultivate superbugs in the human body or natural environment […]

Several genes play a role in whales’ enormous size Biologists have identified evolutionary changes in DNA that allowed whales to grow larger over time. The researchers found that despite having bigger bodies with more chances for cancer to develop in cells, whales have genes that not only contribute to body size but reduce the impacts […]

Scientists have successfully demonstrated that autonomous methods can discover new materials. The artificial intelligence (AI)-driven technique led to the discovery of three new nanostructures, including a first-of-its-kind nanoscale “ladder.” The newly discovered structures were formed by a process called self-assembly, in which a material’s molecules organize themselves into unique patterns. Scientists at Brookhaven’s Center for […]

Scientists find aging mechanism — and how to reverse it Biologists have developed a new model for understanding aging based on the degradation in how DNA is organized and regulated, identifying the epigenome as the predominant factor in the aging process. The findings may help scientists develop treatments to reverse aging and delay the onset […]

Over two-thirds of world’s glaciers will melt by 2100 More than two-thirds of the world’s glaciers will disappear by 2100 if the climate continues to warm at current trends. The global temperature is on track to rise 2.7 degrees Celsius over pre-industrial levels by the end of the century, but scientists note that if future […]

Last year’s Nobel Prize in Physics celebrated the fundamental interest of quantum entanglement, and also envisioned the potential applications in “the second quantum revolution” — a new age when we are able to manipulate the weirdness of quantum mechanics, including quantum superposition and entanglement. A large-scale and fully functional quantum network is the holy grail […]
