Trapping and excitation of the simplest molecule      (via sciencedaily.com)     Original source 

The simplest possible molecule H2+ was one of the very first molecules to form in the cosmos. This makes it significant for astrophysics, but also an important object of research for fundamental physics. It is difficult to study in experiments. However, a team of physicists has now succeeded in measuring the vibrations of the molecule with a laser.

The mutual neutralization of hydronium and hydroxide      (via sciencedaily.com)     Original source 

Researchers have been able to directly visualize the neutral products of the mutual neutralization of hydronium and hydroxide, and report three different product channels: two channels were attributed to a predominant electron-transfer mechanism, and a smaller channel was associated with proton transfer. The two-beam collision experiment is an important step toward understanding the quantum dynamics of this fundamental reaction.

Measuring the properties of light: Scientists realize new method for determining quantum states      (via sciencedaily.com)     Original source 

Scientists have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors -- devices that can detect individual light particles -- for so-called homodyne detection. The ability to characterize optical quantum states makes the method an essential tool for quantum information processing.

Graphene research: Numerous products, no acute dangers found by study      (via sciencedaily.com)     Original source 

Graphene is an enormously promising material. It consists of a single layer of carbon atoms arranged in a honeycomb pattern and has extraordinary properties: exceptional mechanical strength, flexibility, transparency and outstanding thermal and electrical conductivity. If the already two-dimensional material is spatially restricted even more, for example into a narrow ribbon, controllable quantum effects can be created. This could enable a wide range of applications, from vehicle construction and energy storage to quantum computing.

Climate change could push bowhead whales to cross paths with shipping traffic      (via sciencedaily.com)     Original source 

The population of bowhead whales that migrates between the Bering and Beaufort Seas each year is a conservation success story, with today's population nearing -- if not exceeding -- pre-commercial whaling numbers. But climate change is shifting the whales' feeding grounds and migration patterns, potentially pushing them to spend more time in the paths of oncoming ships, according to a new study.

An awkward family reunion: Sea monsters are our cousins      (via sciencedaily.com)     Original source 

The sea lamprey, a 500-million-year-old animal with a sharp-toothed suction cup for a mouth, is the thing of nightmares. A new study discovered that the hindbrain -- the part of the brain controlling vital functions like blood pressure and heart rate -- of both sea lampreys and humans is built using an extraordinarily similar molecular and genetic toolkit.

Mercury levels in tuna remain nearly unchanged since 1971      (via sciencedaily.com)     Original source 

Tuna is one of the most popular seafoods worldwide. But this protein-rich fish can build up high levels of methylmercury from feeding on contaminated prey, like smaller fish or crustaceans. Despite efforts to reduce mercury emissions into the environment, researchers report that levels in tuna appear to be unchanged since 1971. They warn that more aggressive emission reduction targets are needed to start nudging down tuna mercury levels.
