Diners with discerning tastes may be keen to order an entrée featuring shrimp harvested from the waters of the Atlantic. Or perhaps they prefer a Pacific crustacean. But restaurant-goers beware: As the most consumed and highest imported seafood in the U.S., shrimp are vulnerable to food fraud, species substitution and mislabeling.

Detected in 2017 and observable for only a few weeks, the first known interstellar object to pass through the solar system confounded astronomers, sparking speculation it could be a giant snowflake, hydrogen iceberg or piece of a Pluto-like planet – even an alien probe, an idea promoted in a best-selling book.
A new leaf has turned in scientists' hunt for developing cutting-edge materials used in organic light-emitting diode (OLED) TV's, touchscreens, and more.
Farmers in Thailand still largely use chemical herbicides, especially paraquat and atrazine, to control weeds on their farms. According to research by the Office of Agricultural Economics, in 2019, Thailand imported almost 10 million kilograms of paraquat and close to 3.5 million kilograms of atrazine. The residues of these herbicides cause harm to the environment, living creatures, and our health.

Staphylococcus aureus, Clostridioides difficile, Candida auris, Drug-resistant Shigella. These bacteria not only have difficult names to pronounce, but they are also difficult to fight off. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. Antimicrobial resistance is an urgent global public health threat.

On March 13th, 2023, astronomers around the world will mark the 10th anniversary of the inauguration of the Atacama Large Millimeter/submillimeter Array (ALMA), the world’s largest radio telescope. Over the past decade, the international ALMA collaboration— led by the U.S. National Science Foundation’s National Radio Astronomy Observatory (NRAO), the European Southern Observatory (ESO), and the National Astronomical Observatory of Japan (NAOJ)— has revolutionized our understanding of the Universe and unveiled its secrets, from the formation of planets, stars, and galaxies to deciphering the chemistry of the cosmos, and even taking part in capturing the first images of black holes.
A team of Rutgers scientists dedicated to pinpointing the primordial origins of metabolism – a set of core chemical reactions that first powered life on Earth – has identified part of a protein that could provide scientists clues to detecting planets on the verge of producing life. The research, published in Science Advances, has important implications in the search for extraterrestrial life because it gives researchers a new clue to look for, said Vikas Nanda, a researcher at the Center for Advanced Biotechnology and Medicine (CABM) at Rutgers.

Super-resolution microscopy methods are essential for uncovering the structures of cells and the dynamics of molecules. Since researchers overcame the resolution limit of around 250 nanometers (and winning the 2014 Nobel Prize in Chemistry for their efforts), which had long been considered absolute, the methods of microscopy have progressed rapidly.

Researchers worldwide are actively investigating safer alternatives for the storage of natural gas—solidified natural gas (SNG), or natural gas hydrates, may just be the answer. These gas hydrates, however, are currently limited to the small scale of bench-top laboratory experiments. To that end, Professor Praveen Linga from the Department of Chemical and Biomolecular Engineering at the College of Design and Engineering, National University of Singapore, is working on advancing SNG technology for industrial viability.

The injection of bubbles from waves breaking in turbulent and cold high-latitude regions of the high seas is an underappreciated way in which atmospheric gases are transported into the interior ocean. An improved mechanistic understanding of gas exchange in high latitudes is important for several reasons, including to better constrain climate models that are used to predict changes in the ocean inventory of key gases like oxygen and carbon dioxide.
A novel compound that has the potential to starve the bacteria that causes tuberculosis – the world’s leading infectious killer after SARS-CoV2 – is entering human clinical trials.
Electrons in magnetic solids feel each other as an effective magnetic field that forces the electrons’ spins to align. If the arrangement of atoms is not fully symmetric, an additional magnetic force known as Dzyaloshinskii-Moriya Interaction (DMI) can emerge, forcing the spins to reorient and form whirling patterns called skyrmions. Researchers joined two different materials to enable skyrmion generation.
Researchers from Tokyo Metropolitan University have successfully threaded atoms of indium metal in between individual fibers in bundles of transition metal chalcogenide nanofibers.

However, they found no evidence for the same process occurring in serine clusters. In that work they concluded that if two serine molecules can bind together to form a dipeptide, then the next stages of polymerization could probably occur readily.
