Researchers tracked honey bees in the wild using a drone-based system and found that each bee follows its own highly consistent flight path. Some repeated their routes so precisely that they flew only centimeters from where they had flown before. Landmarks like trees helped keep them on track, while uniform areas such as cornfields led to more variation.
Scaffolded DNA and RNA origami is a technique that allows scientists to build tiny, highly precise two- and three-dimensional objects. Because these nanostructures can interact naturally with biological systems, they could have important future uses in health care and agritech.
Steel and metal production are among the largest contributors to global greenhouse gas emissions, accounting for approximately 10% of global CO2 emissions. At the same time, modern technology relies on tailored steels and metals for applications in fields such as mobility, energy, infrastructure, safety and medicine. Hydrogen-based metal production offers a promising CO2-free alternative and goes even further by integrating reduction, alloying and microstructure design into a single production step. However, hydrogen-based metal production still faces a number of challenges on its path to widespread adoption, one of which is the relatively slow reduction kinetics of metal ores at temperatures below 800°C (1,472°F).
Few animals put on a show quite like manakins. In the rainforests of Central and South America, males of these small tropical birds, with strikingly bright plumage, often gather at communal display sites (leks), where they clear their own dance courts and spend much of their lives performing high-speed backflips, snapping their wings like firecrackers, and running through choreographed routines with other males, all to attract a mate.
Many insects will eat almost anything in their sight, such as certain beetles, grasshoppers and locusts, while others are remarkably picky eaters. For example, numerous insect herbivores will feed only on a single plant family or a specific type of tree. But why is this so?

Archaeological evidence from the Canary Islands suggests that by the 11th century, people there were harvesting and processing a variety of fish and other marine organisms—indicating that coastal resources may have played a vital role in the economic system, according to a study published in PLOS One by Jonathan Santana of the University of Las Palmas de Gran Canaria in Spain, and colleagues.
If we're to reach another star, chemical propulsion will not get us there in any reasonable time frame. We're going to need a different propulsion technology, and one of the most promising seems to be a solar sail. These giant reflective surfaces form the basis of many interstellar mission concepts. Combined with giant lasers pushing them, they can be accelerated to speeds unreachable by any other current technologies.
Most people have seen nylon listed as a material on their clothing tags, but nylon is used in an array of other products, too, including automotive parts, wire insulation and medical supplies. Unfortunately, one of the building blocks of nylon, adipic acid, is produced from petroleum-derived benzene through energy-intensive processes and has a rather high carbon footprint. However, there may be a better way to produce this ubiquitous polymer.
In a first, a large, international team led by multiple labs at Harvard Medical School and Princeton University has published a complete wiring diagram of all the connections between neurons in the central nervous system of an adult fruit fly.
Written in the 1860s, Jules Verne’s novels "From the Earth to the Moon" and "All Around the Moon" were highly speculative fiction in their time, but tell a tale that now seems remarkably familiar: three astronauts in a conical capsule on a free-return trajectory around the moon.
A few years ago, Teenage Engineering partnered with designer Yuri Suzuki for a cute lo-fi vinyl cutter. Now the Swedes are going pro with the limited-edition APC-2, a full-sized record cutter for churning out high-quality playback discs.Continue ReadingCategory: Music, Consumer Tech, TechnologyTags: Vinyl, Production
Engineers often treat impurities as a problem to eliminate to improve material performance. But new research from Osaka Metropolitan University and Fraunhofer Institute for Mechanics of Materials IWM suggests that in some cases, a little chemical messiness is exactly what helps materials slide more smoothly. The findings were published in Advanced Science.
The nights surrounding the new moon on June 14 are the perfect time to hunt for planets and sparkling constellations in the late spring sky.
