Herbal teas are enjoyed worldwide, not only for their taste and refreshment but also for a wide range of reputed health benefits. But the potential significance of a category of compounds called lipids in the teas has been relatively unexplored.

A polymer's hidden properties illuminate a world where particles move with unparalleled freedom.

Retrospective analysis finds similar OS, PFS whether or not patients also received chemotherapy

One of the many effects of global warming is sea-level rise due to the melting and retreat of the Earth's ice sheets and glaciers. As the sea level rises, large areas of densely populated coastal land could ultimately become uninhabitable without extensive coastal modification. In order to stave off this possibility, carbon emissions need to reach net negative, a state that is hard to achieve under current…

David W. Brown writes about the OSIRIS-REx mission to collect material from an asteroid that could help us learn more about the origins of life on Earth.

Associate Professor Yoshi N. Sasaki, a specialist in Physical Oceanography, is involved in research into rising sea levels—particularly in coastal areas of Japan. He spoke about what he has learned so far about the relationship between ocean currents, sea level and climate change, what research he is currently focusing on, and the appeal of research that uses numerical modeling to uncover natural phenomena.

IntelligentPad was a drag-and-drop software creator based on the concept of reusable components. Pads could be reused on other pads. There was no programming...

The twin issues of climate change and the shortage of fossil fuels are two primary challenges of energy research. Polymer electrolyte fuel cells (PEFCs), which produce the clean fuel hydrogen, are one of the most promising options to tackle both these challenges.

The black particles from an asteroid some 300 million kilometers away look unremarkable, like pieces of charcoal, but they hold a component of life itself.

The building blocks for life on Earth may have actually come from outer space, according to a new discovery by the Japanese Aerospace Exploration Agency (JAXA). Scientists found a number of organic molecules in samples from the asteroid Ryugu, collected in 2019. The molecules include uracil, a building block for RNA, as well as niacin, which is important to metabolism, ScienceAlert writes. "These molecules on Ryugu…

The Okhotsk Sea in the western Pacific Ocean, surrounded by Russia and Japan, is the southernmost sea in the world to freeze seasonally. The northwestern part of this shallow sea is an active sea-ice production area, but why the extent of sea ice varies year to year has remained a mystery.

A new study in the Proceedings of the National Academy of Sciences finds that large-scale fish releases negatively impact ecosystems as a whole, while offering little benefit and some harm to the species they seek to support.

Synthetic hydrogels were shown to provide an effective scaffold for neuronal tissue growth in areas of brain damage, providing a possible approach for....

Paleontologists with Hokkaido University Museum working with a colleague from the American Museum of Natural History has found evidence that suggests one type of dinosaur may have been able to make bird-like calls. In their paper published in the journal Communications Biology, Junki Yoshida, Yoshitsugu Kobayashi and Mark Norell describe their study of a larynx fossil from a Pinacosaurus grangeri dinosaur and…

Hydrothermal vents have been identified as a previously undiscovered source of dissolved black carbon in the oceans, furthering our understanding of the role of oceans as a carbon sink.

Researchers have designed and synthesized analogs of a new antibiotic that is effective against multidrug-resistant bacteria, opening a new front in the fight against these infections.

Abstract: The killing of Abe Shinzo sparked a backlash in Japan against the Unification Church, after the assassin blamed it for his family's destitution and linked the former prime minister to t

Scientists are applying an area of mechanics and mathematics called "chaos theory" to describe the diving behavior of narwhals.

The flecks of rock were brought back to Earth by the Japanese space mission Hayabusa2 in December 2020.
