The blue lobster could have sold for roughly $30 based on her size, but it was decided to donate her to an aquarium to keep her safe instead.

Every second of every day, utilities monitor the flow of power through the nation's electric grid, monitoring whether power generated matches power demanded by homes, businesses, vehicles and more. For every disruption—a substation outage, a felled utility pole, a generator failure—grid operators must work quickly to ensure that power goes where it's needed.

Researchers at Binghamton University, State University of New York have developed a self-powered "bug" that can skim across the water, and they hope it will revolutionize aquatic robotics.

Transport emissions have grown in line with the population and economy. Without intervention, the Australian government expects transport to be the largest emissions source by 2030. So, cutting transport emissions is a crucial, but challenging, element of the net-zero strategy.

Inspired by the paper-folding art of origami, North Carolina State University engineers have discovered a way to make a single plastic cubed structure transform into more than 1,000 configurations using only three active motors. The findings could pave the way for shape-shifting artificial systems that can take on multiple functions and even carry a load—like versatile robotic structures used in space, for example.

Professor Tsumoru Shintake of Okinawa Institute of Science and Technology (OIST) has proposed an extreme ultraviolet (EUV) lithography technology that surpasses the standard in semiconductor manufacturing.

Two new papers, both authored by Mohamed Mehana of the Earth and Environmental Sciences division at Los Alamos National Laboratory, explore the feasibility of well retrofitting and clean hydrogen production from fossil fuels.

The "white gold" of clean energy, lithium is a key ingredient in batteries large and small, from those powering phones and laptops to grid-scale energy storage systems.

The grid needs to change. To electrify everything from vehicles to heating systems to stovetops, the U.S. grid must expand by about 57% and get more flexible, too. Solar and wind energy are the renewables most likely to dominate a future clean energy grid. But they are found primarily in remote areas, far from the hubs that need their power.

In recent years, engineers and scientists worldwide have been working on new technologies for generating electricity from renewable energy sources, including photovoltaics (PVs), wind turbines and hydro-power generators. An alternative solution for mitigating the impact of climate change could be to convert the excess or waste heat generated by industries, households and hot natural environments into electricity.

A new study from SUNY Polytechnic Institute provides a detailed overview of deepfake datasets and identifies key challenges, offering valuable insights for researchers, engineers, and practitioners. It emphasizes the importance of developing proactive detection methods and improving existing datasets to combat deepfake threats effectively.

In 2021, a team led by MIT physicists reported creating a new ultrathin ferroelectric material, or one where positive and negative charges separate into different layers. At the time, they noted the material's potential for applications in computer memory and much more. Now the same core team and colleagues—including two from the lab next door—have built a transistor with that material and shown that its properties are so useful that it could change the world of electronics.

The sprawling Park Fire, near Chico — which officials say was sparked after a man pushed a burning car into a gully and then fled — was only 12% contained.

Freshwater scarcity affects over two billion people in the world, primarily in arid and remote regions, as well as islands and coastal areas without freshwater sources. Climate change and population growth are only making the problem worse, and existing methods require an energy input, usually electrical.

A decarbonized steel industry that includes carbon dioxide removal techniques in its net zero arsenal could use lower-grade iron ore, according to a new study.

Strategically planting perennial grass throughout corn and soybean fields helps address the unintended environmental consequences of growing the dominant row crops, including soil erosion, fertilizer runoff and greenhouse gas emissions.

As 5G technologies continue to evolve, scientists and engineers are already exploring new ways to turn things up a notch for 6G. One of the biggest challenges to address in both 5G and 6G is the many detrimental effects that operating at extremely high frequencies has on wireless communications. At frequencies nearing the terahertz range, problems such as signal attenuation and interference are more prominent, and maintaining signal integrity becomes much harder.

An algorithm developed by Washington State University researchers can better find data anomalies than current anomaly-detection software, including in streaming data.

Deep learning models, such as those used in medical imaging to help detect disease or abnormalities, must be trained with a lot of data. However, often there isn't enough data available to train these models, or the data is too diverse.

Engineering researchers at the University of Minnesota Twin Cities have demonstrated a state-of-the-art hardware device that could reduce energy consumption for artificial intelligent (AI) computing applications by a factor of at least 1,000.
