Feb. 8, 2024 Researchers have discovered a previously unknown ability of a group of immune system cells, known as Atypical B cells (ABCs), to fight infectious diseases such as malaria. The scientists say ABCs ...
Feb. 8, 2024 Researchers report the results of the first ever genome-wide association study (GWAS) of a biosafety level 4 (BSL-4) virus. The team found two key human genetic factors that could help explain why ...
Feb. 8, 2024 Scientists have discovered a tiny worm species that infects and kills insects. These worms, called nematodes, could control crop pests in warm, humid places where other beneficial nematodes are ...
Feb. 1, 2024 Researchers have traced the origin and evolutionary trajectory of plant immune receptors. Their discovery will make it easier to identify immune receptor genes from genomic information and could help ...
Jan. 31, 2024 A new study has analyzed plant spore dispersion at its source, where rain droplets shake flexible leaves to initially disperse ...
Jan. 31, 2024 Insect-killing bacteria typically release toxins to slay their hosts. The bacterium Photorhabdus luminescens, for example, pumps insect larvae full of the lethal 'Makes caterpillars floppy ...
Jan. 30, 2024 To find poison ivy before it finds you, scientists have published a new study in which they show how they used artificial intelligence to confirm that an app can identify poison ivy. The app is not ...
Jan. 26, 2024 The spread of West Nile virus in Europe is strongly linked to agricultural activities, urbanization, and bird migration, according to new ...
Jan. 18, 2024 Life on Earth runs on a 24-hour cycle as the planet turns. Animals and plants have built-in circadian clocks that synchronize metabolism and behavior to this daily cycle. But one beetle is out of ...
Jan. 12, 2024 The so-called Rice Yellow Mottle Virus (for short: RYMV) is responsible for high crop losses in Africa, particularly among small-scale farmers. A research team has now produced rice lines that are ...
Jan. 9, 2024 New research delves into the intricate defense mechanisms of tomatoes against the notorious bacterial pathogen, Pseudomonas syringae pv. tomato (Pst). It's a classic tale of nature's arms ...
Jan. 8, 2024 Certain populations of mosquitoes are more heat tolerant and better equipped to survive heat waves than others, according to new ...
Jan. 4, 2024 The dynamic lifecycle of the malaria parasite means that the density of the Plasmodium can suddenly drop below the level of detection in asymptomatic people -- especially when older, less sensitive ...
Jan. 4, 2024 Scientists have engineered the microbiome of plants for the first time, boosting the prevalence of 'good' bacteria that protect the plant from disease. The findings could substantially ...
Dec. 22, 2023 Researchers found that a Transient Receptor Potential (TRP) A1 stimulant, 2-methylthiazoline (2MT), act as a potent insect repellent in Drosophila. 2MT induces aversive behaviors via olfactory, ...
Dec. 22, 2023 At about the size of a pinkie nail, the jellyfish species Cladonema can regenerate an amputated tentacle in two to three days -- but how? Regenerating functional tissue across species, including ...
Dec. 18, 2023 Research along James River in Richmond suggests that climate change could shorten window for predators to prey on ...
Dec. 18, 2023 Researchers have determined the structure of the most common material in our genomes. New treatments for autoimmune diseases, cancer and neurodegeneration may ...
Dec. 15, 2023 In a study of lab-engineered cells, researchers identify how the immune system neutralizes the herpesvirus. The research maps, for the first time, the maneuvers used by virus and host in the cell ...
Dec. 5, 2023 Researchers have uncovered the intricate molecular mechanism used by parasitic phytoplasma bacteria, known for inducing 'zombie-like' effects in ...
