Around 180,000 avoidable deaths over 14 years in fast-growing tropical cities were caused by a rapid rise in emerging air pollution, a study has revealed.

Researchers have uncovered how Gram-negative bacteria — which cause a variety of drug-resistant infections — build their protective outer layer, which could lead to more effective treatments.

Intestinal epithelial cells line the inner wall of the gut, creating a barrier to dangerous bacteria like enteropathogenic E. coli that seek to attach and efface that barrier, causing diarrhea. Such pathogens pose significant risks to human health and …

Researchers have developed a fully integrated high-power laser on a lithium niobate chip, paving the way for high-powered telecommunication systems, fully integrated spectrometers, optical remote sensing, and efficient frequency conversion for quantum …

A new study finds that liberals and conservatives differ in how they perceive dominance in women, which may influence their likelihood to vote them into political office.

Researchers have combined reinforcement learning with numerical methods to compute turbulent flows, one of the most complex processes in engineering. The researchers also used machine learning algorithms to accelerate predictions in simulations of comp…

Researchers have used CRISPR gene editing — a type of ‘molecular scissors’ — to understand how deletions in one area of the genome can affect the expression of nearby genes. The work will help researchers investigate new therapeutic approaches for on…

Accurate home testing could be used for a wider range of illnesses, as new research shows the capability of smartphone-powered tests for Dengue Fever.

High-income nations are responsible for 74 percent of the global excess in resource extraction over the 1970-2017 period, driven primarily by the United States and the countries of the European Union. This is demonstrated in an international study, whi…

During cell division in a mother cell, the 23 chromosomes that carry the human genome must be first copied and later delivered to two newly forming daughter cells. At least in healthy cells, the result is astonishingly flawless, and no chromosome is ev…

Scientists have developed a new technique for rejuvenating skin cells. This technique has allowed researchers to rewind the cellular biological clock by around 30 years according to molecular measures, significantly longer than previous reprogramming m…

A new study has found using indoor fans more often allows people to reduce their air conditioner use without changing how hot they feel, paving a way for reducing future energy use and greenhouse gas emissions.

Physicists have developed the most sensitive method ever for measuring the potential energy of an atom (within a hundredth of a decillionth of a joule — or 10-35 joule), and used it to validate one of the most tested theories in physics — quantum ele…

Researchers from the Okinawa Institute of Science and Technology Graduate University have produced a comprehensive genome of the false clownfish, which could be used to answer a myriad of biological questions.

Researchers have developed a wearable device that plays specific sounds to enhance deep sleep. The first clinical study has now shown that the device is effective, but not at the same level of effectiveness for everyone.

The mere motions of breathing are known to influence vital functions of the lungs, including their development in babies, the production of air-exchange-enhancing fluid on their inner surfaces, and maintenance of healthy tissue structure. Now, new rese…

In a new study, University of California, Berkeley, engineers describe a major breakthrough in the design of a component of transistors — the tiny electrical switches that form the building blocks of computers — that could significantly reduce their …
