Picky eaters by day, buffet by night: Butterfly, moth diets sync to plant aromas
The scent of blooming flowers and fresh plant life is not just a perk of springtime; it is a key driver in the survival and evolution of butterflies and moths.

Drug-delivering aptamers target leukemia stem cells for one-two knockout punch
Drug-carrying DNA aptamers can deliver a one-two punch to leukemia by precisely targeting the elusive cancer stem cells that seed cancer relapses, researchers report. The aptamers -- short single-strand snippets of DNA that can target molecules like larger antibodies do -- not only deliver cancer-fighting drugs, but also are themselves toxic to the cancer stem cells, the researchers said. 04/03/2025 06:31 PM
Physicists uncover electronic interactions mediated via spin waves
Physicists have made a novel discovery regarding the interaction of electronic excitations via spin waves. The finding could open the door to future technologies and advanced applications such as optical modulators, all-optical logic gates, and quantum transducers. 04/03/2025 06:31 PM
Climate change and prehistoric human populations: Eastward shift of settlement areas at the end of the last ice age
An archaeological study of human settlement during the Final Palaeolithic revealed that populations in Europe did not decrease homogenously during the last cold phase of the Ice Age. Significant variation in regional population sizes indicate differentiated reactions nested in an overall shift of settlement areas towards the east. 04/03/2025 02:39 PM
Successful therapy confirmed for newborns with the fatal metabolic disorder MoCD type A
Early administration of the drug Fosdenopterin/rcPMP improves the chances of survival of infants with MoCD type A and promotes the development of brain functions. 04/03/2025 02:39 PM
MIT engineers develop a way to mass manufacture nanoparticles that deliver cancer drugs directly to tumors
Researchers developed a manufacturing technique that rapidly generates large quantities of nanoparticles coated with drug-delivering polymers, which hold great potential for treating cancer. The particles can be targeted directly to tumors, where they release their payload while avoiding many of the side effects of traditional chemotherapy. 04/03/2025 02:38 PM
Researchers find intestinal immune cell prevents food allergies
Researchers found that a small population of immune cells in the mouse intestine prevents allergic responses to food, suggesting that targeting such cells therapeutically could potentially lead to a new treatment for allergies. 04/03/2025 02:38 PM
New vaccine concept tackles harmful bacteria in the intestine
In the fight against bacterial pathogens, researchers are combining vaccination with targeted colonization of the intestine by harmless microorganisms. This approach could potentially mark a turning point in the antibiotics crisis. 04/03/2025 02:38 PM
Cellular regulator of mRNA vaccine revealed... offering new therapeutic options
A team of researchers has uncovered a key cellular mechanism that affects the function of mRNA vaccines and therapeutics. Their study provides the first comprehensive understanding of how mRNA vaccines are delivered, processed, and degraded within cells -- a breakthrough that could pave the way for more effective vaccines and RNA-based treatments. 04/03/2025 02:37 PM
Animal behavioral diversity at risk in the face of declining biodiversity
Drastic declines in biodiversity due to human activities present risks to understanding animal behaviors such as tool use, according to new research. Shrinking animal populations make the study of these behaviors increasingly difficult, underscoring the urgency of targeted conservation efforts and inclusive conservation strategies. Action is needed not only for research, but also to respect our shared cultural heritage with animal species. 04/03/2025 02:37 PM
Powerful new software platform could reshape biomedical research by making data analysis more accessible
A powerful new software platform is set to transform biomedical research by allowing scientists to conduct complex and customized data analyses without advanced programming skills. The web-based platform enables scientists to analyze and visualize their own data independently through an intuitive, interactive interface. 04/03/2025 02:37 PM
Revealing capillaries and cells in living organs with ultrasound
While medical centers use ultrasound daily, so far this technology has not been capable of observing body tissues at the scale of cells. Physicists have now developed a microscopy technique based on ultrasound to reveal capillaries and cells across living organs -- something that wasn't possible before. 04/03/2025 02:37 PM
How the brain and inner ear are formed
Researchers have developed a method that shows how the nervous system and sensory organs are formed in an embryo. By labeling stem cells with a genetic 'barcode', they have been able to follow the cells' developmental journey and discover how the inner ear is formed in mice. The discovery could provide important insights for future treatment of hearing loss. 04/03/2025 02:37 PM
How GPS helps older drivers stay on the roads
New research shows that Sat Nav systems are helping keep older drivers on the roads for longer. The study reveals that over 65s with a poorer sense of direction rely more on help from GPS navigation systems such as Sat Nav or smartphone maps. Those using GPS tended to drive more frequently -- suggesting that the technology helps older people maintain driving independence. 04/03/2025 02:37 PM
Machine learning helps construct an evolutionary timeline of bacteria
Scientists have helped to construct a detailed timeline for bacterial evolution, suggesting some bacteria used oxygen long before evolving the ability to produce it through photosynthesis. 04/03/2025 02:36 PM
Runaway battery improves safety
Overheating batteries are a serious risk, in the worst cases leading to fires and explosion. A team has now developed a simple, cost-effective method to test the safety of lithium-ion batteries, which opens up opportunities for research into new and safer batteries for the future. The researchers created an intentionally unstable battery which is more sensitive to changes that could cause overheating. The battery is one-fiftieth the size of conventional batteries, so is less resource intensive and tests can be carried out in a smaller lab environment. 04/03/2025 12:31 PM
An answer to green energy in hydrogen-generating marine microbes
A genomic study of hydrogen-producing bacteria has revealed entirely new gene clusters capable of producing large volumes of hydrogen. 04/03/2025 12:30 PM
Bees actively adjust flower choice based on color and distance: Updating 'flower constancy' beyond Darwin's theory
Since Darwin's time, the phenomenon known as flower constancy -- i.e., where insects consistently visit the same flower type even when many others are also present -- has been understood as a passive behavior to reduce the effort of remembering different flower types. However, researchers have now shown via experimentation with bees that this behavior is an active strategy in which bees balance the time required for memory retrieval and moving between flowers, thereby realizing efficient foraging. 04/03/2025 12:30 PM
Corpse flowers are threatened by spotty recordkeeping
Plant biologists examined records for nearly 1,200 individual corpse flower plants from 111 institutions around the world. The data and records were severely lacking and not standardized. Without complete information, conservationists were unable to make informed decisions about breeding their plants. Out of the plants studied, 24% were clones and 27% were offspring from closely related individuals. Low genetic diversity could lead to further endangerment and even extinction. 04/03/2025 12:29 PM
