Nutritionists have been touting the health benefits of seafood for years. Dietary guidelines recommend that the average adult get at least two servings of seafood per week. But the push to increase our consumption of seafood can put a strain on the seafood industry and create more waste.

The COVID-19 pandemic that shuttered cities around the world did not just affect the way we work, study and socialize. It also affected our mobility. With millions of workers no longer commuting, vehicle traffic across Canada has plummeted. This has had a significant impact on the quality of air in major Canadian cities, according to a new study by Concordia researchers.

The first Arab interplanetary mission reached Mars' orbit Tuesday in the most critical stage of its journey to unravel the secrets of weather on the Red Planet.

Rice University researchers have created a "defective" catalyst that simplifies the generation of hydrogen peroxide from oxygen.

The United Arab Emirates' "Hope" probe on Monday successfully entered Mars' orbit, making history as the Arab world's first interplanetary mission.

Materials scientists typically use solution-phase transmission electron microscopy (TEM) to reveal the unique physiochemical properties of three-dimensional (3-D) structures of nanocrystals. In a new report on Science Advances, Cyril F. Reboul and a research team at the Monash University, Australia, Seoul National University, South Korea, and the Lawrence Berkeley National Laboratory U.S., developed a single-particle Brownian 3-D reconstruction method. To accomplish this, they imaged ensembles of... Читать дальше...

A team of researchers affiliated with several institutions in China and one in Germany, has found evidence of a 2,700‐year‐old face cream for men at a Chinese dig site. In their paper published in the journal Archaeometry, the group describes items they found at the dig site and the face cream they discovered.

A team of researchers affiliated with a host of institutions in China, along with one from Australia, one from Taiwan and one from the U.S., has found evidence that contradicts the finding of a prior effort that reported ancient human teeth found at a dig site in China were 120,000 years old. In their paper published in Proceedings of the National Academy of Sciences, the group describes how they tested the teeth and what they found.

Using the AstroSat spacecraft, Indian astronomers have performed multiwavelength observations of a Narrow-Line Seyfert 1 (NLS1) galaxy known as Mrk 335. Results of this investigation, presented in a paper published February 1 on the arXiv preprint server, deliver crucial information about the emission from this source.

About half of our genome is made up of transposable elements (TEs), also known as transposons. These 'jumping genes' are short stretches of DNA that have the unique ability to duplicate themselves and change their position within our code. While these philanderings play an essential role in the evolution of the species, if unchecked, transposons can wreak havoc on the genome.

The Atala butterfly (Eumaeus atala) and its five closest relatives in the genus Eumaeus like to display their toxicity. This sextet's toxicity comes from what they eat as caterpillars: plants called cycads that have been around since before dinosaurs roamed the Earth and contain a potent liver toxin called cycasin.
