Snakes of the Bothrops neuwiedi complex are widely distributed and represent medically important species in Brazil. Here, we report compositional and functional profiles of the venom of seven species of Bothrops neuwiedi group: Bothrops mattogrossensis, Bothrops pauloensis, Bothrops pubescens, Bothrops diporus, Bothrops neuwiedi, Bothrops marmoratus, and Bothrops erythromelas. Toxin composition of individual and pooled venoms showed remarkable inter- and intraspecific variability of the relative abundance of toxins

Quantitative assessment of prokaryotic organisms remains one of the most fundamental yet challenging tasks in microbiology. This difficulty arises from several intrinsic biological characteristics, including their abundance, exponential replication, and species diversity. Additionally, bacterial growth follows a four-phase pattern: lag, log (exponential), stationary, and death phases. Accurate estimation of microbial concentration is essential for identification,

How could we learn about our solar system? How did the planets form, their ends, how did life form on Earth, and are there other life forms in the universe? The key to these questions lies in understanding exoplanets.  Exoplanets, by definition, mean planets outside the solar system orbiting another star.  The first exoplanets were

Scientists may finally know why Jupiter and Saturn have very different weather patterns at their poles, despite having similar sizes and compositions. The discovery could help researchers probe deep into the interiors of these giant gaseous planets. Observations of the two solar system gas giants have revealed that Jupiter‘s north pole hosts a central polar

When NASA scientists opened the sample return canister from the OSIRIS-REx asteroid sample mission in late 2023, they found something astonishing. Dust and rock collected from the asteroid Bennu contained many of life’s building blocks, including all five nucleobases used in DNA and RNA, 14 of the 20 amino acids found in proteins, and a

A trawler in the Southern Ocean Shutterstock A treaty that will protect areas of the largely lawless high seas from fishing has come into force, marking a “turning point” for ocean conservation. International waters outside the exclusive economic zones that stretch 370 kilometres from countries’ coasts are sometimes known as a “wild west” where there

A 30-minute stroll across New York’s Central Park separates Trump Tower from the American Museum of Natural History. If the US president ever found himself inside the museum he could see the Cape York meteorite: a 58-tonne mass of iron taken from northwest Greenland and sold in 1897 by the explorer Robert Peary, with the
