NewsScientists build robot to track plant-fungal trade networks, revealing nature’s underground supply chains
New research uses advanced robotics to track the hyper-efficient supply chains formed between plants and mycorrhizal fungi as they trade carbon and nutrients across the complex, living networks that help regulate the Earth’s atmosphere and ecosystems.

NewsBacteria in polymers form cables that grow into living gels
Scientists have discovered that bacterial cells growing in a solution of polymers, such as mucus, form long cables that buckle and twist on each other, building a kind of “living Jell-O.”

NewsThese bacteria perform a trick that could keep plants healthy
Researchers have shown that some types of soil bacteria can influence a plant’s balance of growth and defense. The bacteria produce an enzyme that can lower a plant’s immune activity and allow its roots to grow longer than they would otherwise.

NewsPlankton bloom off Madagascar linked to drought in South Africa
Researchers show that dust from drought-stricken Southern Africa caused a bloom of marine phytoplankton off the southeast Madagascar coast from November 2019 through February 2020.

NewsBacterial ‘flipping’ allows genes to assume different forms
A new study has shown that inversions, which cause a physical flip of a segment of DNA and change an organism’s genetic identity, can occur within a single gene, challenging a central dogma of biology — that one gene can code for only one protein.

NewsFuture enterovirus outbreaks could be exacerbated by climate change
A common set of drivers can explain the timing of outbreaks of both hand, foot and mouth disease and polio, according to a recent study which suggests these summertime outbreaks may hint at implications for climate change.

NewsSimple test for flu could improve diagnosis and surveillance
A low-cost CRISPR-based paper strip test distinguishes between influenza types and can be reprogrammed to recognize different viruses including the H5N1 bird flu virus.

NewsScientists unravel drivers of the global zinc cycle in our oceans
The important role of the Southern Ocean in global biological processes and the carbon cycle has been confirmed by a study that, for the first time based on field evidence, reveals the underappreciated role of inorganic zinc particles in these cycles.

News750,000 deaths linked to antimicrobial resistance could be prevented every year, World Health Assembly hears
Improving and expanding existing methods to prevent infections could prevent over 750,000 deaths associated with AMR every year in LMICs (low and middle income countries), estimates a new modelling analysis.

NewsGeologists and biologists unearth atomic fingerprints of cancer using fermenting yeast
Researchers have discovered that cancer cells may be made from a different assortment of hydrogen atoms than healthy tissue, findings which could give doctors new strategies for studying how cancer grows and spreads.

NewsResearchers produce guidelines to tackle science’s ‘AI problem’
With growing evidence revealing deep flaws in how machine learning is used in science, an interdisciplinary team of 19 researchers has published guidelines for the responsible use of AI in science.

NewsWild nematode worms learn to avoid harmful bacteria—and their offspring inherit this knowledge
The nematode worm C. elegans will stay away from dangerous bacteria in its environment when exposed to certain bacterial RNAs—and can transmit that learned behavior to future generations.

NewsAcid-tolerant yeast engineered to produce valuable organic acid from plants
Researchers have engineered an acid-tolerant yeast to economically produce succinic acid, a key chemical in food, agricultural and pharmaceutical products, savings on money and emissions.

NewsEavesdropping viruses wait for bacterial signals before switching to kill mode
Researchers have found that dozens of viruses respond to quorum sensing or other chemical signals from bacteria.
