NewsAI and citizen science reveal potential first detection of invasive malaria mosquito in Madagascar
Researchers used AI and citizen science to identify what may be the first Anopheles stephensi mosquito ever detected in Madagascar — a species capable of spreading deadly malaria across urban Africa. A single smartphone photo submitted through NASA’s GLOBE Observer app led to the discovery.

NewsViral infections at the heart of why honey bees overthrow their queen
Common viral infections shrink a queen bee’s ovaries, reducing both her egg-laying capacity and her production of methyl oleate, a pheromone that normally keeps worker bees loyal. When methyl oleate levels drop, workers will “smell” the queen’s weakness - and begin preparing her successor.

NewsScientists to probe how microbes break down water-soluble polymers in wastewater
Scientists and industry have teamed up to investigate how microbes in wastewater interact with and potentially biodegrade polymers called viscosifiers.

NewsMissing nutrient in breast milk may explain health challenges in children of women with HIV
A new study reveals that breast milk from women living with HIV contains significantly lower levels of tryptophan, an essential amino acid likely important for infant immune function, growth, and brain development.

NewsScientists develop novel gene therapy for hereditary hearing loss
Scientists have introduced an innovative gene therapy method to treat impairments in hearing and balance caused by inner ear dysfunction. The treatment holds promise for treating a wide range of mutations that cause hearing loss.

NewsScientists identify cells by seeing how high they levitate
A new cell-sorting device uses electromagnetic levitation to precisely direct the movement of cells. It can be used to separate different types of cells — cancer cells from healthy cells, or live cells from dead cells, for example — with many potential applications in the lab and in the clinic.

NewsScientists develop floral-scented fungus that lures mosquitoes to their doom
Taking advantage of the mosquito’s natural attraction to flowers, an international team of researchers engineered a new strain of Metarhizium fungus that imitates a flower’s sweet scent and lures the bloodsucking bugs to their deaths.

NewsPowered by mushrooms, living computers are on the rise
Researchers have discovered that common edible fungi, such as shiitake mushrooms, can be grown and trained to act as organic memristors, a type of data processor that can remember past electrical states. They could also be used to create other types of low-cost computing components.

NewsResearchers discover microbes turning food waste into energy
Researchers have identified a previously unknown microbe that plays a crucial role in converting food waste into renewable natural gas, using a molecular tagging approach that could also detect other elusive microbes - including those that are breaking down microplastics in the ocean.

NewsLighting up life: scientists develop glowing sensors to track cellular changes as they happen
Researchers have engineered living cells to use a 21st amino acid that illuminates protein changes in real time, providing a new method for observing changes within cells. The technique is effective in bacteria, human cells and live tumor models, making it possible to study complex diseases like cancer more ethically.

NewsStudy identifies viral combinations that heighten risk of severe respiratory illnesses in infants
A new study has revealed that, while a wide range of viruses can cause lower respiratory tract illnesses (LRIs) in infants, certain viruses and viral combinations dramatically increase the risk of severe disease.

NewsStudy uncovers origins of urban human-biting mosquito, shedding light on uptick in West Nile virus spillover from birds to humans
The research disproves the theory that the mosquito evolved in the London underground by dating the mosquito’s origin back over 1,000 years and identifies the genetic links between bird-biting and human-biting mosquitoes, key to West Nile transmission.
