New Findings Revolutionize What We Understand About America’s Forests

Posted by in categories: climatology, sustainability

Forests serve as crucial players in the fight against climate change due to their ability to absorb and store carbon. A recent study, with contributions from researchers at Northern Arizona University, is poised to revolutionize forest conservation strategies across the United States. This study introduces innovative and precise models designed to more accurately estimate and forecast the carbon storage capacity of forests.

The U.S. Forest Service, along with an impressive list of research partners including those at Northern Arizona University, has introduced new National Scale Volume Biomass (NSVB) models that provide a consistent and scientifically accurate method to predict tree volume, biomass (a term that describes the collective mass of the woody parts of trees) and carbon content nationwide.

Revolutionizing Electric Car Batteries: MIT’s Cost-Efficient, Cobalt-Free Solution

Posted by in categories: energy, sustainability, transportation

“I think this material could have a big impact because it works really well,” said Dr. Mircea Dincă. “It is already competitive with incumbent technologies, and it can save a lot of the cost and pain and environmental issues related to mining the metals that currently go into batteries.”


Electric vehicles (EVs) have become a household name in the last few years with several companies fighting to compete in the everchanging EV landscape as EV technology continues to improve in cost, efficiency, and the materials used to manufacture the batteries responsible for sustaining this clean energy revolution. While EV batteries have traditionally used cobalt for their battery needs, a recent study published in ACS Central Science discusses how organic cathode materials could be used as a substitute for cobalt for lithium-ion batteries while potentially offering similar levels of storage capacity and charging capabilities, as cobalt has shown to be financially, environmentally, and socially expensive.

“Cobalt batteries can store a lot of energy, and they have all of features that people care about in terms of performance, but they have the issue of not being widely available, and the cost fluctuates broadly with commodity prices,” said Dr. Mircea Dincă, who is a W.M. Keck Professor of Energy at MIT and a co-author on the study.

Insect Conservation and Solar Energy: A Five-Year Study Reveals Surprising Results

Posted by in categories: solar power, sustainability

“This research highlights the relatively rapid insect community responses to habitat restoration at solar energy sites,” said Leroy Walston.


How could solar energy facilities contribute to insect populations? This is what a recent study published in Environmental Research hopes to address as a team of researchers investigated how insect and plant populations in re-established habitats comprised of wildflowers and native grasses changed during a five-year period in the vicinity of photovoltaic (PV) solar array parks. This study holds the potential to help scientists, engineers, and conservationists gain greater insight into the ecological impact of solar farms on newly planted vegetation.

For the study, the researchers surveyed two solar sites located approximately 100 miles (160 km) apart in southern Minnesota, Eastwood Solar Site and Atwater Solar Site, between 2018 and 2022 for changes in insect and plant populations on restored land with native forbs and grasses. After conducting 358 observations of across sites, the researchers found increases in the biodiversity of both sites, including plant species and total insect abundance.

From Earth to Space: Insights and Discoveries from SSPD-1’s Mission

Posted by in categories: satellites, solar power, sustainability

Solar energy is traditionally known for using massive solar panels that collect sunlight and convert it into clean energy, but what if this same energy was instead beamed from satellites in orbit around the Earth, known as space solar power? This is the goal of Space Solar Power Demonstrator (SSPD-1), which is a 110-pound (50-kilogram) project run by the California Institute of Technology (Caltech). SSPD-1 was launched onboard the SpaceX Transporter-6 mission on January 3, 2023, and recently concluded its mission after conducting a series of experiments, including the ability to wirelessly beam solar power from space to Earth, which it accomplished in early 2023.

“Solar power beamed from space at commercial rates, lighting the globe, is still a future prospect. But this critical mission demonstrated that it should be an achievable future,” said Dr. Thomas F. Rosenbaum, who is the President of Caltech and the Sonja and William Davidow Presidential Chair and professor of physics.

SSPD-1 successfully demonstrated three experiments during its one-year mission: DOLCE (Deployable on-Orbit ultraLight Composite Experiment), ALBA, and MAPLE (Microwave Array for Power-transfer Low-orbit Experiment). DOLCE demonstrated the architecture necessary for developing space solar power, ALBA demonstrated how to harness solar energy in space, and MAPLE demonstrated how this energy could be wirelessly beamed to Earth.

Waymo’s Driverless Cars Are Hitting the Highway Sans Safety Drivers in Arizona

Posted by in categories: business, robotics/AI, sustainability, transportation

To back up the decision, Waymo pointed to its safety record and history building and operating self-driving trucks on highways. (The company shuttered its self-driving truck project last year to focus on taxis.) Including highways should also decrease route times for riders—especially from the airport—with some rides taking half the time.

Although highways are simpler to navigate than city streets—where cars contend with twists, turns, signs, stoplights, pedestrians, and pets—the stakes are higher. A crash at 10 or 20 miles per hour is less likely to cause major injury than one at highway speeds. And while it’s relatively straightforward (if less than ideal) for a malfunctioning robotaxi to stop or pull to the side of the road and await human help in the city, such tactics won’t do on the highway, where it’s dangerous for cars to suddenly slow or stop.

Nebraska-Led Study Reveals Impact of Groundwater Depletion on Crop Yields from Drought and Dry Conditions

Posted by in categories: climatology, economics, sustainability

How can the increased threat of drought and drier conditions from climate change impact groundwater (aquifer) usage, and ultimately, food production? This is what a recent study partially funded by the U.S. Department of Agriculture and published in Nature Water hopes to address as a team of researchers led by the University of Nebraska-Lincoln investigated how decreasing aquifer levels result in irrigation challenges for farmers now only in the United States but throughout the world.

This study holds the potential to help scientists, farmers, and policymakers better understand the appropriate steps to manage irrigation levels as climate change continues to lead to increased drought and drier environmental conditions across the globe.

“In terms of things that let you address food security under extreme conditions — in particular, drought and climate change — we really can’t do without irrigation,” said Dr. Nick Brozović, who is a professor of agricultural economics at the University of Nebraska–Lincoln and a co-author on the study. “If we want to feed the world with high-quality, nutritious food and a stable food supply, we need to irrigate.”
