Butterflies can see more of the world than humans, including more colors and the field oscillation direction, or polarization, of light. This special ability enables them to navigate with precision, forage for food, and communicate with one another. Other species, like the mantis shrimp, can sense an even wider spectrum of light, as well as the circular polarization, or spinning states, of light waves. They use this capability to signal a “love code,” which helps them find and be discovered by mates
Pipeline inspection is a crucial aspect of maintaining the integrity, safety, and reliability of the planet’s energy infrastructure. However, due to cost and scale challenges, infrastructure operators struggle to conduct accurate, large-scale inspections.

An MIT team uses computer models to measure atomic patterns in metals, essential for designing custom materials for use in aerospace, biomedicine, electronics, and more. Massachusetts Institute of Technology, Cambridge, MA The concept of short-range order (SRO) - the arrangement of atoms over small distances - in metallic alloys has been underexplored in materials science and engineering. But the past decade has seen renewed interest in quantifying it, since decoding SRO is a crucial step toward developing tailored high-performing alloys, such as stronger or heat-resistant materials. Understanding how atoms arrange themselves is no easy task and must be verified using intensive lab experiments or computer simulations based on imperfect models. These hurdles have made it difficult to fully explore SRO in metallic alloys

Phased array radar technology has been gaining popularity since its initial introduction in the 1960s and is now being used in a variety of applications, from military and defense to civilian sectors and even space exploration. This cutting-edge technology has revolutionized radar systems by offering unparalleled flexibility, precision, and speed. At the heart of phased array radar lies a sophisticated antenna system composed of numerous individual elements, each capable of independently emitting and receiving radio waves. Unlike traditional radar systems that rely on mechanically rotating antennas, phased array radars electronically steer their beams, enabling rapid and precise target acquisition. This breakthrough is made possible by meticulously controlling the phase of radio waves emitted from each antenna element
Case Construction Equipment launched its first electric vehicle (EV) products last year - the CX15EV mini excavator and the SL22EV small articulated loader - and the company has more in store for 2024, starting with the commercial release of the industry's first purpose-built electric backhoe loader. After years of design and development, the new 580EV retains the dimensional loading and digging specifications and delivers the same breakout forces as the four-wheel-drive, 97-hp (72-kW) 580SN diesel model. Case first debuted its Project Zeus electric backhoe concept at CONEXPO in 2020 (www.sae.org/news/2020/03/conexpo---case-580-ev-backhoe), but the production 580EV is a vastly different machine than what was on display in Las Vegas
Transdermal technology has been around for a very long time. The popularity of patches, consisting of plant, animal or mineral extracts, dates back to the building of the pyramids in ancient Egypt and in Babylonian medicine, around 3000 BC. 1 So why are transdermal patches so effective
Neurostimulators, also known as brain pacemakers, send electrical impulses to specific areas of the brain via special electrodes. It is estimated that some 200,000 people worldwide are now benefiting from this technology, including those who suffer from Parkinson’s disease or from pathological muscle spasms. According to Mehmet Fatih Yanik, professor of neurotechnology at ETH Zurich, further research will greatly expand the potential applications: instead of using them exclusively to stimulate the brain, the electrodes can also be used to precisely record brain activity and analyze it for anomalies associated with neurological or psychiatric disorders. In a second step, it would be conceivable in future to treat these anomalies and disorders using electrical impulses
Lasers are essential tools for observing, detecting, and measuring things in the natural world that we can’t see with the naked eye. But the ability to perform these tasks is often restricted by the need to use expensive and large instruments
In the realm of ear health, accurate diagnosis is crucial for effective treatment, especially when dealing with conditions that can lead to hearing loss. Traditionally, otolaryngologists have relied on the otoscope, a device that provides a limited view of the eardrum’s surface. This conventional tool, while useful, has its limitations, particularly when the tympanic membrane (TM) is opaque due to disease
Cooling strategies are evolving to meet the needs of tomorrow's improved EVs. At the heart of innovations that have powered EV range and performance improvements lies the pursuit of efficiency. Today's electric drivetrains convert over 85% of a battery's electrical energy into mechanical energy. By comparison, internal combustion engines (ICEs) convert less than 40% of their fuel's chemical energy into mechanical energy. As a result of this greater efficiency, we have seen major gains in electric motor performance, with today's motors operating at up to 25,000 rpm compared to the 15,000 rpm common ten years ago. So, what's driving this increase in efficiency? As with any complex system, there are several variables at play: optimized winding configurations, improvements in magnet layout and materials, and better integration between components. However, one of the major heroes of EV efficiency improvements has been thermal management technologies
In physical chemistry, time-resolved spectroscopy is the study of dynamic processes in materials or chemical compounds. Within this field, various techniques including transient absorption spectroscopy are used to study the mechanistic and kinetic details of chemical processes that occur within just a few picoseconds to a femtosecond — the equivalent of one millionth of one billionth of a second
ASV has introduced a pair of compact track loaders, the VT-75 and RT-65. Both models feature a Yanmar Tier 4 Final rated diesel engine. The VT-75 is equipped with a 74.3-hp (55.4-kW) engine, while the RT-65 is fitted with a 67.1-hp (50-kW) unit. “The VT-75 truly allows our ASV customers to do more,” said Peter Ovrebo, product management director at Yanmar North America. “It fits right into the heart of the construction market where operators can make the best use of it.” Ovrebo also stated the RT-65 is “redesigned from top to bottom, making it an entirely new model that promises to allow operators an easier and more productive time on the jobsite in virtually every way
Outsized costs for charging infrastructure could slow implementation of battery-electric CVs. The high cost of batteries to electrify on-road commercial vehicles is one thing. But some connected with or studying electrification for the CV sector now are concerned that the cost of installing high-capacity recharging infrastructure for EV versions of trucks, buses and other on-road commercial vehicles is the latest factor with potential to derail the growth of CV electrification. One prominent study from earlier this year pegged the cost to the freight industry and utilities at a resounding near-$1 trillion to fully electrify all commercial vehicles over the course of roughly 20 years. And that cost is for infrastructure only, exclusive of the vehicles themselves, “which can be two to three times as expensive as their diesel-powered equivalents,” the report asserted
Researchers are bringing together multiple areas of technical expertise to improve LVAD performance and outcomes.
