Origins of Earth's most powerful ocean current revealed

Climate change may reduce yields of crops like corn and soybeans, but it can also give some plants an edge. That's one of the takeaways of a recent study of tall goldenrod, a common wildflower that runs rampant in fields across its native range in North America and other parts of the world where it has been introduced.

Materials that repel water are used in countless applications, including industrial separation processes, routine laboratory pipetting, and medical devices. When water touches these surfaces, the interface where they meet tends to acquire a small electrical charge—an effect that is ubiquitous, yet poorly understood. KAUST researchers have now studied this in detail and their findings could have broad implications. The findings are published in the journal Langmuir.

The theory of panspermia holds that life is spread through the cosmos via asteroids, comets, and other objects. When the building blocks of life emerge on one planet, impacts can eject surface material into space, which then carries these seeds to other worlds. For decades, scientists have debated whether this could have occurred between Earth and Mars (in both directions). However, the recent controversy over the possible existence of microbial life in Venus's dense clouds has sparked discussio

Researchers at the Institute of Industrial Science, The University of Tokyo and George Mason University's College of Science have developed a new method that improves air temperature forecasts one to five weeks in advance—without requiring additional model simulations. The methodology, detailed in the Proceedings of the National Academy of Sciences, provides a dual benefit, not requiring significant increase in computational cost while improving predictions.
