‘Oceans are hugely complex’: modelling marine microbes is key to climate forecasts
Marine microorganisms are crucial for ocean health. Bacteria, archaea, fungi, algae and viruses make up most of the biomass in the seas and form the base of marine food webs. They support nutrient cycling and drive crucial biogeochemical processes, including key steps in the carbon, nitrogen and silicon cycles. But the climate crisis is putting…

Rapid and sensitive detection of Pseudomonas aeruginosa by isothermal amplification combined with Cas12a-mediated detection
Abstract CRISPR based technologies have been used for fast and sensitive detection of pathogens. To test the possibility of CRISPR based detection strategy in Pseudomonas aeruginosa infections, a combined method of recombinase polymerase amplification followed by Cas12a-mediated detection via fluorescence reader or lateral flow biosensor (named Cas12a-RCFL) has been established in this study. The Cas12a-RCFL…

Overlooking vegetation loss outside forests imperils the Brazilian Cerrado and other non-forest biomes
The global emphasis on halting forest loss has failed to recognize the biodiversity and ecosystem services provision of non-forest biomes such as the Brazilian Cerrado. Here, we stress the urgent need to address their destruction, including at the upcoming UN Conference of the Parties (COP28), and for coordinated efforts to protect these non-forest ecosystems amid…

Five ways in which rookie lab leaders can get up to speed
Credit: miakievy/Getty Shortly after launching her laboratory last year, Catherine Schrankel began looking for people to fill it. Without a team, Schrankel had to do everything: hire students, organize freezers and establish protocols, among the many other responsibilities of a new principal investigator (PI). “I was just not prepared for how tired I would be…

A model-independent redundancy measure for human versus ChatGPT authorship discrimination using a Bayesian probabilistic approach
Abstract The academic and scientific world in general is increasingly concerned about their inability to determine and ascertain the identity of the writer of a text. More and more often the question arises as to whether a scientific article or work handed in by a student was actually produced by the alleged author of the…

How five researchers fared after their ‘great resignation’ from academia
Geologist Chris Jackson says viewing yourself as part of a larger effort is a useful skill when transitioning out of academia.Credit: London International Youth Science Forum On 9 September, Elizabeth Gadd, a research-culture specialist at Loughborough University, UK, posted a collage of pictures of 35 people who had recently used the #leavingacademia hashtag on X,…

Unusually high room and elevated-temperature tensile properties observed in direct aged wire-arc directed energy deposited Inconel 718
Abstract Wire-arc directed energy deposition (DED) processed Inconel (IN) 718 is known to have coarse columnar grains, strong texture, and significant chemical and microstructural inhomogeneity in the as-fabricated condition. Homogenization treatment is commonly used prior to aging to eliminate the inhomogeneity and detrimental precipitation for better mechanical properties. In this study, however, direct aging (DA)…

A classification method for soybean leaf diseases based on an improved ConvNeXt model
Abstract Deep learning technologies have enabled the development of a variety of deep learning models that can be used to detect plant leaf diseases. However, their use in the identification of soybean leaf diseases is currently limited and mostly based on machine learning methods. In this investigation an enhanced deep learning network model was developed…

How big is science’s fake-paper problem?
Software will help publishers to detect fake articles produced by paper mills.Credit: Getty The scientific literature is polluted with fake manuscripts churned out by paper mills — businesses that sell bogus work and authorships to researchers who need journal publications for their CVs. But just how large is this paper-mill problem? An unpublished analysis shared…
