Quails could be the unknown reservoir of Tuscany and Sicilian viruses
Quails could be the unknown reservoir of the Toscana virus (TOSV) and the Sandfly Fever Sicilian virus (SFSV), mosquito-borne pathogens that can infect domestic animals and also cause disease in humans. This conclusion is drawn from a study published.....»»
Saturday Citations: Mars limnology, phage immunology, quantum technology. Plus: The mushrooms are coming
This week, we reported on LIGO upgrades, parasitic fungi and a new analysis of Curiosity rover data. Also, did you know that viruses also attack bacteria? But at that scale, it's a lot less like catching a cold and a lot more like Harry Dean Stanton.....»»
Mammalian cells may consume bacteria-killing viruses to promote cellular health
Bacteriophages, also called phages, are viruses that infect and kill bacteria, their natural hosts. But from a macromolecular viewpoint, phages can be viewed as nutritionally enriched packets of nucleotides wrapped in an amino acid shell......»»
Pro-Russia hackers target inboxes with 0-day in webmail app used by millions

Exploring cell-to-cell signals in plants that trigger photosynthesis and defense mechanisms
Traffic lights signal to cars and buses when to stop, slow and go. Much like traffic lights, plant cells send signals to each other to perform photosynthesis to grow or fight off destructive viruses and pathogens......»»
New exoplanet-informed research sets clearer bounds on the search for radio technosignatures
In a new study published in The Astronomical Journal, researchers used the known population of exoplanets and extrapolated to the much larger, unknown population of exoplanets to set better thresholds for planetary effects on signals from ETIs (extra.....»»
Nanocarriers study shows antibodies against polyethylene glycol in 83% of the German population
It has long been known that people can form defenses and thus antibodies against viruses. But antibodies can also develop against polyethylene glycol (PEG), a substance used in cosmetics, food and medicine. These influence the effectiveness of drugs......»»
Broad-spectrum antiviral candidate targets dengue and SARS-CoV-2
A broad-spectrum antiviral drug candidate, 2-thiouridine, that targets positive-strand RNA viruses has been identified and characterized......»»
New water trumpet species found in the Philippines
With the help of three citizen scientists, an unknown Cryptocoryne population was found in one of the streams of Zamboanga del Norte province, Philippines, in March 2023. After careful morphological studies and literature review, researchers from Xis.....»»
Scientists discover new molecule that combats viral infection in bacteria
A Ph.D. researcher at the University of St Andrews studying microbes in the human gut has discovered a new molecule that acts as a "distress signal" when viruses are detected. The research is published in the journal Nature......»»
Physical theory improves protein folding prediction
Proteins are important molecules that perform a variety of functions essential to life. To function properly, many proteins must fold into specific structures. However, the way proteins fold into specific structures is still largely unknown. Research.....»»
“Cisco buried the lede.” >10,000 network devices backdoored through unpatched 0-day

Q&A: Demystifying the biology of growing older
Exercise. Social connections. Sunscreen. It seems there is no shortage of advice on how to stay young, but among scientists, the exact physiology behind aging remains unknown. Tufts Now asked biology professor Mitch McVey to decode the latest and mos.....»»
Uncovering previously unexplored cellular mechanisms
Single-cell and spatially resolved omics have helped scientists take a closer look at tissue composition, structure, and function. This comprehensive understanding paves the way for them to uncover some intricate and previously unknown disease mechan.....»»
Nitrogen enrichment delays the emergence of an aridity-induced threshold for plant biomass
Crossing certain aridity thresholds in global drylands can lead to abrupt decays of ecosystem attributes such as plant productivity, potentially causing land degradation and desertification. It is largely unknown, however, whether these thresholds ca.....»»
