The rate of ground-breaking scientific discoveries and technological innovation is slowing down despite an ever-growing amount of knowledge, according to an analysis released Wednesday of millions of research papers and patents.

While previous research has shown downturns in individual disciplines, the study is the first that “emphatically, convincingly documents this decline of disruptiveness across all major fields of science and technology,” lead author Michael Park told AFP.

Park, a doctoral student at the University of Minnesota’s Carlson School of Management, called disruptive discoveries those that “break away from existing ideas” and “push the whole scientific field into new territory.”

It’s an early step forward and needs way more testing. But the potential is high. Cancer vaccines aren’t a new idea. They use the same fundamentals that enable vaccines for infectious pathogens like viruses and bacteria: priming our immune system into recognizing and attacking something that’s harmful to our bodies.

Nuclear morphology changes with aging, but the role of these changes and the underlying mechanisms are not fully understood. The authors find that the nuclear envelope anchor protein ANC-1 in worms, and its counterpart nesprin-1 and nesprin-2 in mammals, promotes the degradation of nuclear components to limit nucleolar size and function in a soma longevity and germline immortality mechanism.

If you’ve ever thought your children in elementary school were “smarter” than you, or at least quicker at taking up new skills and knowledge, new research published in the journal Current Biology confirms that you were correct. According to the new study, there are differences in the brain messenger GABA between kids and adults, which may explain why kids often seem to be more capable of learning and retaining new information.

“Our results show that children of elementary school age can learn more items within a given period of time than adults, making learning more efficient in children,” said Takeo Watanabe of Brown University.

According to the study, children experienced a rapid increase in GABA during visual training, which lasted even after the training ended. In contrast, GABA concentrations in adults remained constant during training. These findings suggest that children’s brains are more responsive to training, allowing them to quickly and efficiently consolidate new learning.

SEOUL (Reuters) — South Korea’s antitrust regulator said it would impose a 2.85 billion won ($2.2 million) fine on Tesla Inc for failing to tell its customers about the shorter driving range of its electric vehicles (EVs) in low temperatures.

The Korea Fair Trade Commission (KFTC) said that Tesla had exaggerated the “driving ranges of its cars on a single charge, their fuel cost-effectiveness compared to gasoline vehicles as well as the performance of its Superchargers” on its official local website since August 2019 until recently.

The driving range of the U.S. EV manufacturer’s cars plunge in cold weather by up to 50.5% versus how they are advertised online, the KFTC said in a statement on Tuesday.

The way electrons interact with photons of light is a vital part of many modern technologies, from lasers to solar panels to LEDs. But the interaction is inherently weak because of a major mismatch in scale: the wavelength of visible light is about 1,000 times larger than an electron, so the way the two things affect each other is limited by that disparity.

Now, researchers at The University of Hong Kong (HKU), MIT and other universities say they have come up with an innovative way to make more robust interactions between photons and electrons possible, that produces a hundredfold increase in the emission of light from a phenomenon called Smith-Purcell radiation. The findings have potential ramifications for both commercial applications and fundamental scientific research, although it will require more years of investigation to put into practice.

The findings are published in Nature by Dr. Yi Yang (Assistant Professor of the Department of Physics at HKU and a former postdoc at MIT), Dr. Charles Roques-carmes (Postdoctoral Associate at MIT) and Professors Marin Soljačić and John Joannopoulos (MIT professors). The research team also included Steven Kooi at MIT’s Institute for Soldier Nanotechnologies, Haoning Tang and Eric Mazur at Harvard University, Justin Beroz at MIT, and Ido Kaminer at Technion-Israel Institute of Technology.
