Comprehensive screening analysis of organohalogen compounds in blubber samples of 11 toothed whale species stranded on Japanese coasts revealed species-specific accumulation profiles, with a total of more than 300 organohalogen compounds detected. For the first time, the composition profiles of marine natural products were found to be useful indicators of the feeding habitats and migration…
Bacterial pathogens, such as those causing rice bacterial blight, tomato bacterial wilt, and kiwifruit bacterial canker, pose significant threats to global agriculture. However, effective pesticides to control these diseases are scarce, with copper-based bactericides and antibiotics offering limited efficacy and posing environmental risks. Bacterial pathogens, such as those causing rice bacterial blight, tomato bacterial wilt, and…
Described in a paper that appears today in the journal Nature Astronomy, the discovery means habitable exoplanets could have started forming much earlier — before the first galaxies formed and billions of years earlier than was previously thought. The post Water was Already Present in Primordial Universe 100-200 Million Years after Big Bang appeared first…
Astronomers using the NASA/ESA Hubble Space Telescope have produced a beautiful new image of the intermediate spiral galaxy NGC 5042.

A research team led by Prof. Long Shibing from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has, for the first time, made spintronic neuromorphic devices based on CoO/Pt heterostructure. The study is published in Nano Letters. A research team led by Prof. Long Shibing from the University…

When a droplet of water falls on a hot pan, it dances across the surface, skimming on a thin layer of steam like a tiny hovercraft; this is known as the Leidenfrost effect. But now, researchers know what happens when a hot droplet falls on a cool surface. When a droplet of water falls on a…
Researchers in Sweden report a green alternative to reduce reliance on mining graphite, the raw source behind the “wonder material” graphene. In the journal Small, researchers at KTH Royal Institute of Technology say they have developed a reproducible and scalable method for producing graphene oxide (GO) nanosheets from commercial carbon fibers, marking a breakthrough in…
A team of scientists have developed a method to illuminate the dynamic behavior of nanoparticles, which are foundational components in the creation of pharmaceuticals, electronics, and industrial and energy-conversion materials. The advance, reported in the journal Science, combines artificial intelligence with electron microscopy to render visuals of how these tiny bits of matter respond to…
Since the financial crisis of 2008, the stock market has seen a remarkable migration of investor money away from active management and toward passive, or index, funds. As a result, the “Big Three” asset managers—BlackRock, Vanguard and State Street—have swiftly ballooned into behemoths. Taken together, they constitute the largest shareholder in more than 40% of…
