Since the 1960s, scientists who study X-rays, lightning and similar phenomena have observed something curious: In lab experiments replicating these occurrences, electrons accelerated between two electrodes can be of a higher energy than the…
Biologists have identified a new gene in California poplar trees (Populus trichocarpa) — named BOOSTER — that enhances photosynthesis and can boost tree height.
Transgenic hybrid poplar with increased expression levels of BSTR enhanced…
Creating realistic 3D models for applications like virtual reality, filmmaking, and engineering design can be a cumbersome process requiring lots of manual trial and error.
While generative artificial intelligence models for images can streamline…
Ancient North Americans are looking more and more like experienced mammoth killers.
Archaeologists have long debated whether the Clovis people, who lived around 13,000 years ago, had the know-how and technology to regularly hunt the…
