Giant Spider Provides Promise of Pain Relief for Irritable Bowel Syndrome

Molecules from the venom of one of the world's largest spiders could help researchers tailor pain blockers for people with irritable bowel syndrome ...

Biologists Create New Genetic Systems to Neutralize Gene Drives

Addressing concerns about gene drive releases in the wild, scientists have developed two new genetic systems that halt or eliminate gene drives after release. Created in fruit flies, the e-CHACRs and ...

Rising Temperatures Could Shift US West Nile Virus Transmission

West Nile virus spreads most efficiently in the US at temperatures between 24-25 degrees Celsius (75.2-77 degrees Fahrenheit), a new study ...

Scientists have developed a tool for studying the biting behavior of common pathogen-carrying ...

How Plants Ensure Regular Seed Spacing

Biologists have examined how seed formation is coordinated with fruit growth. They explain the genetic control mechanisms underlying the ...

Putting a Future Avocado 'Apocalypse' on Ice

For the first time, an Australian cryogenics scientist has shown that avocado shoot tips can be successfully frozen and revived -- and that's great news for future generations of the ...

Prior Exposure to Powdery Mildew Makes Plants More Vulnerable to Subsequent Disease

A key to surviving in the wild is fighting off infection -- and not just once. For plants, as with humans, one infection may or may not leave a plant with lasting immunity. Biologists conducted a ...

New Malaria Transmission Patterns Emerge in Africa

An international study reveals how future climate change could affect malaria transmission in Africa over the next ...

Helminth Infections Common in Medieval Europe, Grave Study Finds

Although helminth infections -- including tapeworms and roundworms -- are among the world's top neglected diseases, they are no longer endemic in Europe. However, researchers report that these ...

Mosquito Immune System Mapped to Help Fight Malaria

Scientists have created the first cell atlas of mosquito immune cells, to understand how mosquitoes fight malaria and other infections. Researchers discovered new types of mosquito immune cells, ...

Reduce Insecticide Spraying by Using Ant Pheromones to Catch Crop Pests

Scientists have developed a molecular sponge that soaks up the pheromones of ants and releases them slowly to attract the pests to an insecticide ...

Researchers Reveal Molecular Structures Involved in Plant Respiration

New research provides the first-ever, atomic-level, 3D structure of the largest protein complex (complex I) involved in the plant mitochondrial electron transport chain. The results could unlock new ...

Meet Hedge Fund Managers of Avian World

New research finds that brood parasites living in more variable and unpredictable habitats tend to parasitize -- or squat and drop their eggs in -- the nests of a greater variety and number of ...

What Kind of Animal Transports the Seeds of the World's Smallest Fruit-Bearing Plants?

Balanophora have some of the smallest fruits among angiosperms, leading researchers to question how the seeds of these plants are dispersed. Very little is currently known about their seed dispersal ...

Biomedical Scientists Piece Together How Medication Paralyzes Parasitic Worms

A new study upends the widely held belief that a medication used to treat lymphatic filariasis doesn't directly target the parasites that cause the disease. The research shows the medication, ...

New Building Block in Plant Wall Construction

Researchers have uncovered a new biochemical mechanism fundamental to plant life. They have now detailed the enzymatic reaction involving carbohydrates present in plant cell walls, which are ...

Survival of the Fit-Ish

It can be hard to dispute the common adage 'survival of the fittest'. After all, 'most of the genes in the genome are there because they're doing something good,' says a ...

Source of Pathogen That Causes Bitter Rot Disease

Fungal spores responsible for bitter rot disease, a common and devastating infection in fruit, do not encounter their host plants by chance. Turns out, they have a symbiotic association with the ...

Research Gets to the Heart of Organ Shape in Nature

Researchers have shed fresh light on the evolution and function of the shapes we see in nature - using as a model the heart shaped fruits of the Capsella ...

Insect Diversity Boosted by Combination of Crop Diversity and Semi-Natural Habitats

To enhance the number of beneficial insect species in agricultural land, preserving semi-natural habitats and promoting crop diversity are both needed, according to new ...

'Insect Apocalypse' May Not Be Happening in US

Scientists have been warning about an 'insect apocalypse' in recent years, noting sharp declines in specific areas -- particularly in Europe. A new study shows these warnings may have been ...

Malaria Discovery Could Expedite Antiviral Treatment for COVID-19

New research into malaria suggests targeting enzymes from the human host, rather than from the pathogen itself, could offer effective treatment for a range of infectious diseases, including ...

How Maths Modelling Helps Efforts to Eradicate Banana Bunchy Top Virus

Modelling the predicted movements of pervasive sap-sucking tiny insects before they infest banana crops has the potential to become a key tactic in the fight against a devastating virus, according to ...
