A new, high-performance all-electric motorcycle just hit the streets, bringing an incredible 250-mile (400-km) NEDC range, in addition to a few tricks that may, thanks to a reported capability to self-balance and actually follow you around, according to a new webpage from Da Vinci Dynamics.
The new approach, which takes cues from NASA’s methods for sending data through deep space, could revolutionize EV infrastructures by enabling electric vehicles and autonomous factory machines to charge while driving.
Just about anywhere you look, there are birds. Penguins live in Antarctica, ptarmigan in the Arctic Circle. Rüppell’s vultures soar higher than Mt. Everest. Emperor penguins dive deeper than 1,800 feet. There are birds on mountains, birds in cities, birds in deserts, birds in oceans, birds on farm fields, and birds in parking lots.
Given their ubiquity—and the enjoyment many people get from seeing and cataloging them—birds offer something that sets them apart from other creatures: an abundance of data. Birds are active year-round, they come in many shapes and colors, and they are relatively simple to identify and appealing to observe. Every year around the world, amateur birdwatchers record millions of sightings in databases that are available for analysis.
All that monitoring has revealed some sobering trends. Over the last 50 years, North America has lost a third of its birds, studies suggest, and most bird species are in decline. Because birds are indicators of environmental integrity and of how other, less scrutinized species are doing, data like these should be a call to action, says Peter Marra, a conservation biologist and dean of Georgetown University’s Earth Commons Institute. “If our birds are disappearing, then we’re cutting the legs off beneath us,” he says. “We’re destroying the environment that we depend on.”
A two-year expedition to coral reefs in the Pacific Ocean detected half a million types of microbes, the latest estimate in the quest to quantify the planet’s microbiome.
The big picture: There is intense debate among scientists about how many different types of bacteria and other microorganisms live on Earth — information that could aid conservation of species and fragile ecosystems brimming with biodiversity.

A new electrode design could form part of a battery able to last more than 4,000 charge cycles.
Caltech’s recent breakthrough has moved us closer to achieving the transformative potential of space-based solar power.
The mammalian retina is a complex system consisting out of cones (for color) and rods (for peripheral monochrome) that provide the raw image data which is then processed into successive layers of neurons before this preprocessed data is sent via the optical nerve to the brain’s visual cortex. In order to emulate this system as closely as possible, researchers at Penn State University have created a system that uses perovskite (methylammonium lead bromide, MAPbX3) RGB photodetectors and a neuromorphic processing algorithm that performs similar processing as the biological retina.
Panchromatic imaging is defined as being ‘sensitive to light of all colors in the visible spectrum’, which in imaging means enhancing the monochromatic (e.g. RGB) channels using panchromatic (intensity, not frequency) data. For the retina this means that the incoming light is not merely used to determine the separate colors, but also the intensity, which is what underlies the wide dynamic range of the Mark I eyeball. In this experiment, layers of these MAPbX3 (X being Cl, Br, I or combination thereof) perovskites formed stacked RGB sensors.
The output of these sensor layers was then processed in a pretrained convolutional neural network, to generate the final, panchromatic image which could then be used for a wide range of purposes. Some applications noted by the researchers include new types of digital cameras, as well as artificial retinas, limited mostly by how well the perovskite layers scale in resolution, and their longevity, which is a long-standing issue with perovskites. Another possibility raised is that of powering at least part of the system using the energy collected by the perovskite layers, akin to proposed perovskite-based solar panels.
Researchers not only want to further develop printable solar cells technologically. Rather, they want to provide solutions with them in order to implement different application variants.
Scientists say they’ve successfully transmitted solar energy gathered in orbit down to the Earth’s surface.
