Global oceans were warmer last month than any other May in records stretching back to the 19th century, the European Union’s climate monitoring unit reported Wednesday.

Sea temperatures at a depth of about 10 meters were a quarter of a degree Celsius higher than ice-free oceans in May averaged across 1991 to 2020, according to the Copernicus Climate Change Service (C3S).

Year-round, long-term trends have added 0.6C to the ocean’s surface waters in 40 years, said C3S deputy director Samantha Burgess, noting that April had also seen a new record for heat.

Human influences have the potential to reduce the effectivity of communication in bees, adding further stress to struggling colonies, according to new analysis.

Scientists at the University of Bristol studying honeybees, bumblebees and stingless bees found that variations in communication strategies are explained by differences in the habitats that bees inhabit and differences in the social lifestyle such colony size and nesting habits.

The findings, published today in PNAS, reveal that anthropogenic changes, such as habitat conversion, climate change and the use of agrochemicals, are altering the world bees occupy, and it is becoming increasingly clearer that this affects communication both directly and indirectly; for example, by affecting food source availability, social interactions among nestmates and their cognitive functions.

A pair of food tech startups have teamed up to create what they say are the world’s first lab-grown fish filets — and they used a 3D printer to serve them.

The challenge: Demand for seafood is expected to nearly double by 2050 due to a growing population and increasing incomes, but overfishing, climate change, ocean pollution, and other factors pressure the seafood industry’s ability to satisfy the world’s hunger for fish.

WASHINGTON, May 30 (Reuters) — Former U.S. State Department and nuclear regulatory officials on Tuesday urged the U.S. Energy Department to reconsider a plan to use bomb-grade uranium in a nuclear power experiment, saying that its use could encourage such tests in other countries.

The Energy Department and two companies aim to share costs on the Molten Chloride Reactor Experiment (MCRE) at the Idaho National Laboratory and use more than 1,322 pounds (600 kg) of fuel containing 93% enriched uranium.

Bill Gates-backed company TerraPower LLC, the utility Southern Co (SO.N) and the department hope the six-month experiment will lead to breakthroughs in reactors that could help reduce pollution linked to climate change.

An ancient, methane-spewing volcano has been discovered at the bottom of the Arctic Ocean.

A team of engineers at the University of Massachusetts Amherst has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air. The secret lies in being able to pepper the material with nanopores less than 100 nanometers in diameter. The research appeared in the journal Advanced Materials.

“This is very exciting,” says Xiaomeng Liu, a graduate student in electrical and computer engineering in UMass Amherst’s College of Engineering and the paper’s lead author. “We are opening up a wide door for harvesting clean electricity from thin air.”

“The air contains an enormous amount of electricity,” says Jun Yao, assistant professor of electrical and computer engineering in the College of Engineering at UMass Amherst, and the paper’s senior author. “Think of a cloud, which is nothing more than a mass of water droplets. Each of those droplets contains a charge, and when conditions are right, the cloud can produce a lightning bolt—but we don’t know how to reliably capture electricity from lightning. What we’ve done is to create a human-built, small-scale cloud that produces electricity for us predictably and continuously so that we can harvest it.”

Last February, the Biden administration unveiled its $5 billion plan to expand EV charging infrastructure across the country. Not only with the Department of Transportation help states build half a million EV charging stations by 2030, the White House also convinced Tesla to share a portion of its existing Supercharger network with non-Tesla EVs. On Thursday, Ford became the first automaker to formalize that pact with Tesla, announcing during a Twitter Spaces event that “Ford electric vehicle customers access to more than 12,000 Tesla Superchargers across the U.S. and Canada,” starting in Spring 2024, per the company release.

Because Teslas uses a proprietary charger port design for its vehicles, Ford owners will initially need to rely on a Tesla-developed adapter connected to the public charging cable in order to replenish their Ford F-150 Lightning, Mustang Mach-E and E-Transit vehicles. Ford also announced that, beginning with the 2025 model year, it will switch from the existing Combined Charging System (CCS) port to Tesla’s now open-source NACS charge port. These 12,000 additional chargers will join Ford’s 84,000-strong Blue Oval charging station network.

“Tesla has led the industry in creating a large, reliable and efficient charging system and we are pleased to be able to join forces in a way that benefits customers and overall EV adoption,” Marin Gjaja, chief customer officer of Ford Model e, said in the release. “The Tesla Supercharger network has excellent reliability and the NACS plug is smaller and lighter. Overall, this provides a superior experience for customers.”

Electron, Rocket Lab’s small satellite launch vehicle, launched twice, just ~2 weeks apart from the companies Launch Complex 1 in Mahia, New Zealand to deliver the 4 CubeSat constellation to orbit.

Payload deployment confirmed! Congratulations to the launch team on our 37th Electron launch, and to our mission partners at @NASA @NASA_LSP @NASAAmes: the TROPICS constellation is officially on orbit! pic.twitter.com/xAy7ltg7m1

The two missions, dubbed ‘Rocket Like a Hurricane’ and ‘Coming to a Storm Near You,’ contain two 11.8-lb (5.34 kg) CubeSats each delivered to a 30-degree orbital inclination in order for the constellation to monitor tropical systems forming in the Atlantic and Pacific Ocean and will be capable of performing scans about once every hour.

Electrifying transportation is an essential step towards mitigating climate change. To improve the power, efficiency and safety of electric vehicles, researchers must continue to develop better batteries.

All-solid-state lithium batteries (SSBs), which have a solid electrolyte instead of a liquid, are safer than traditional lithium-ion batteries because they are less flammable and more stable at higher temperatures. They could also have higher energy densities than lithium-ion batteries, allowing for longer lasting batteries in smaller sizes for portable electronics and other applications.

A research team led by Joshua Gallaway of Northeastern University in Boston and scientists at the Department of Energy’s (DOE) Argonne National Laboratory recently tested how the composition of thick cathodes affected electrochemical reactions in SSBs. The team used the resources of the Advanced Photon Source (APS), a DOE Office of Science user facility at Argonne. Their discoveries were published in the journal ACS Energy Letters.
