Phys.org / Honeybees adjust their dances based on information reliability, study reveals
A new study demonstrates that honeybees can evaluate the reliability of their own communication, actively adjusting the vigor of their "waggle dance" based on the truthfulness of the information they provide. By manipulating ...
Medical Xpress / Colorectal tumors use mitochondrial complex II to stockpile iron, but eliminating it causes cell death
Scientists know that colorectal cancer cells require large amounts of iron and that as cancer becomes more aggressive, the cells have even higher amounts of iron. Normal cells with high levels of iron would undergo a type ...
Phys.org / Real-time microscopy reveals how semiconductor nanowires grow, and how bismuth seeds can speed their formation
Scientists from the National Graphene Institute at the University of Manchester and Sun Yat-sen University have captured the growth of semiconducting tellurium nanostructures in liquid in real time, revealing how tiny seed ...
Phys.org / Comb jelly embryos reveal embryonic signaling center shared across early animal evolution
In order for vertebrate embryos to develop their body axes, they require what is known as an embryonic signaling center. This group of cells provides the instructions that determine where up and down, left and right, and ...
Phys.org / Competition from Chinese imports is causing CO₂ emissions to rise globally, research reveals
Danish companies emit less CO₂ when they relocate certain tasks abroad. At the same time, emissions rise correspondingly in those countries. However, global emissions increase when companies are under pressure from cheap ...
Tech Xplore / Heat waves: Five reasons why Victorian houses are cooler than modern buildings
More than 4 million homes were built in the U.K. during the Victorian era. Victorian homes were constructed long before the complex computer models used today to design buildings were invented. Yet these homes, built more ...
Medical Xpress / Pakistani genomes reveal 34,000 knockouts that could explain why mouse-based drugs fail in humans
A comprehensive analysis of 173,303 genomes from Pakistan, published today in Nature, is upending how scientists understand human genetics and drug development. By identifying 34,000 people who are "human knockouts," with ...
Dialog / When less is more: Scaling law explains why ultrathin materials get stronger as they get thinner
One of the most fascinating aspects of physics is that nature often behaves in ways that seem completely counterintuitive. A good example comes from ultrathin materials. If I take a sheet of material and make it thinner ...
Medical Xpress / Shingles vaccine may lower dementia risk, study suggests
Older adults who received a shingles vaccine after a stay in a skilled nursing facility had a 24% lower risk of being diagnosed with dementia over a four-year period than those who were not vaccinated, according to a new ...
Phys.org / Bacteria reveal 'glue' protein that fastens antibiotic-resistant outer membrane to cell wall
Researchers at the University of Notre Dame and collaborators have discovered a key process in how the outer membrane of gram-negative bacteria attaches to the cell wall, advancing the understanding of how these bacteria ...
Phys.org / How evolution can make cells smaller without slowing down their growth
A new study led by Marco Fumasoni, principal investigator at Fundação GIMM, shows that evolution can substantially reduce cell size without significantly compromising cells' ability to grow. The work, carried out in yeast ...
Tech Xplore / Ease of use is key to exoskeleton adoption, engineers show
Wearable exoskeletons can help reduce physical strain in the workplace and protect employees from injury, but the technology has yet to achieve widespread adoption. A new study published in PLOS One by engineers at The University ...
