It's dark and rich and back in the top spot. "Chocolate is back at No. 1 among U.S. ice cream flavors, with butter pecan gaining ground and richer options continuing to rise in popularity, according to a new survey," reports Taylor Leach of Farm Journal. "After briefly ceding the No. 1 spot to vanilla in 2024, chocolate has reclaimed the lead in 2026." Michael Dykes, the International Dairy Foods Association president, told Leach, "Americans’ love for ice cream is as strong as ever."

After weeks of surging gasoline prices with no end in sight, some Americans might be wondering what all goes into the cost of a gallon of gas. Robert I. Harris, an energy economist, breaks down gas prices for The Conversation. "The price of a retail gallon of gas is the sum of four things: the cost of crude oil, refining, distribution and marketing, and taxes. . . . In nationwide figures from January 2026, crude oil accounted for about 51% of the pump price, refining roughly 20%, distribution and marketing about 11% and taxes about 18%." Harris adds that since crude oil is the biggest component of gasoline, when its price spikes on the global market, gas prices go up.

In rural Indiana, some farming families are "leaning on the law" to keep unwanted drones off their lands, reports Greg Weaver of Indiana Capital Chronicle. "Hoosiers in rural Indiana say drones are unlawfully tracking deer for poachers, inexplicably flying around chicken coops, and increasingly making people uneasy." Although many Indiana farmers considered shooting down the snooping drones, they learned that wasn't legal. "So they’ve found other ways to combat the rascals. . . . Farmers fearful that drones might be spreading disease among livestock recently persuaded the Indiana General Assembly to pass a law that prohibits the devices from being used to harm or harass farm animals."

When it comes to serving up energy for hungry grids in rural Virginia, sometimes smaller is better. "The Blue Ridge Power Agency, which serves a string of nonprofit utilities in central and western Virginia, is set to go live this summer with a collection of five batteries of about 5 megawatts each," reports Elizabeth Ouzts of Canary Media. By comparison, larger batteries are typically at least 10 megawatts; however, both sizes aim to store energy when it's less expensive and plentiful. Blue Ridge Power's new batteries will "help two rural electric co-ops and the city of Salem’s utility save money" by releasing battery-stored energy "when high demand on the grid spikes prices." Unlike their larger cousins, smaller batteries are cheaper and faster to build.

It's hard to be more remote than exploring for signs of life on Mars, which is what the Curiosity Rover spends its time doing. "New research published in Nature Communications details Curiosity’s latest find — never-before-seen organic compounds, including one with a structure similar to DNA precursors," reports Jake Currie for Nautilus. NASA geologist Amy Williams told Nautilus, "The same stuff that rained down on Mars from meteorites is what rained down on Earth, and it probably provided the building blocks for life as we know it on our planet." To send all those compounds back to Earth, Curiosity had to conduct a full orchestra of experiments. The Curiosity also goes by "the little robotic chemist that could."

And now, some really good news: "The rate of suicides among young people in the United States dropped 11% below projections, decreasing most sharply in states with a higher volume of answered 988 calls, a new study has found, reports Ellen Barry of The New York Times. The study's results, published in a research letter in The Journal of the American Medical Association (JAMA), found that 4,372 more adolescents and young adults, ages 15 to 34, are alive today than previously projected. The study's data suggests that the federal government’s 988 suicide prevention hotline rollout, which launched in 2022, is having a positive impact among younger Americans.

It was once a thriving lakeshore; now it's toxic and poisoning residents. Mining lithium might offer a solution.

In the Imperial Valley of southeast California, community members are seeking a solution to the harmful effects of the Salton Sea, reports Jill Johnston and Shohreh Farzan for The Conversation. In addition to emitting a foul smell that permeates neighborhoods, chemical blow-off from the drying lake bed is causing lung problems in children.

Formed in the early 1900s when the Colorado River flooded and breached an irrigation canal, the Salton Sea has been kept afloat by contaminated irrigation runoff from the Imperial Valley's agricultural region, which contains fertilizers, pesticides, salt and toxic metals. What was once a thriving tourist and celebrity attraction in the 1950s is now a toxic, shrinking lake.

“As the lake shrinks, wind blowing across the exposed lake bed kicks up toxic dust left by years of agriculture chemicals and metals washing into the lake,” Johnston and Farzan report. “That dust makes its way into the lungs of the children of the Imperial Valley.”

They even found the effects on lung function near the Salton Sea are greater than what studies find in urban California areas by busy roadways.

Their study following 700 elementary school-age children across five northern Imperial Valley cities for several years shows higher rates of air pollution were linked to overall poorer respiratory health and children living closer to the sea had poorer lung function. They also report 1 in 5, or 20% of, children in the Imperial Valley have asthma, which is much higher than the national rate of 5.4-7%.

One solution to the deteriorating quality of life in the Imperial Valley is a well-done lithium extraction facility, community members told Soumya Karlamangla at The New York Times. The Salton Sea sits on top of $500 billion worth of lithium, enough to provide the entire nation’s demand for decades, Karlamangla explains. The U.S. currently imports most of its lithium as it only has one active lithium mine in Nevada.

The Imperial Valley region has crumbling infrastructure and a high unemployment rate. “The lithium companies could collectively create 1,000 construction jobs and 700 permanent operations jobs,” Karlamangla reports.

Residents worry that a lithium extraction will cause the air pollution to worsen and require more use of the community’s depleting fresh water source, especially if not done correctly, Karlamangla reports. Currently, three companies are trying to extract the metal, but lawsuits from environmental groups and broken promises from geothermal and solar industries have slowed the process.

One company expects to commercially extract lithium by 2028, and the California State Legislature authorized a tax on each pound of lithium extracted, giving 80% to Imperial County communities and 20% to the state for Salton Sea restoration efforts, reports Karlamangla.

U.S. grid needs operators to plan now with a blend of energies including batteries, gas and coal

North American Electric Reliability Corporation graph

Fueled by increased demand and shrinking power options, the U.S. electricity grid is headed toward a reliability crisis. "Tens of millions of people face a growing risk of blackouts over the next five years, according to an annual assessment by the North American Electric Reliability Corporation, a nonprofit organization that works closely with federal regulators," reports Brad Plumer of The New York Times.

As AI data center builds have continued to demand more grid power, many "utilities are retiring older coal- and gas-burning plants and aren’t adding enough generation to dependably meet growing demand," Plumer explains. The report lists regions in Texas, the upper Midwest, the Mid-Atlantic region and the Pacific Northwest as most "at risk of electricity shortfalls."

How electricity is produced is at the heart of electricity reliability and a contentious point of national political debate. "President Trump has said that policies to fight climate change and promote wind and solar energy have weakened the reliability of electric grids, since wind turbines and solar panels can’t run at all hours," Plumer writes. But renewable energy advocates say that "Trump administration efforts to hinder wind and solar projects are depriving the grid of a fast-growing source of power."

Battery build-outs can help regional power operators create a more resilient grid that can meet demand even during extreme heat or cold snaps. "In MISO, a grid spanning 15 states in the Midwest and South, more than one-third of coal plants are set to retire by 2030," Plumer reports. "But the grid operator recently instituted a plan to speed up the connection of new gas plants and batteries over the next five years."

The report offers a list of recommendations for operators to start planning now, including "speeding up permitting processes for new power plants and transmission lines, and policies to ensure that large new sources of demand, such as data centers, don’t overwhelm the grid," Plumer adds. "It also suggests that utilities and grid operators should be careful about shutting down older coal and gas plants too quickly."

A huge U.S. lithium mine needed for EV battery production vs. a flower found nowhere else in the world

Step by step, the Biden administration inches closer to green-lighting ioneer's Rhyolite Ridge lithium mine in Nevada, reports Ernest Scheyder of Reuters. Last week, it "published a key environmental report [which is] the last step needed before approving what would become one of the largest U.S. sources of the electric vehicle battery metal." But some conservationists are adamantly against the mine opening despite its cleaner energy purpose.

Ioneer's path to opening has been ongoing for at least six years while the project was reviewed. "The Bureau of Land Management published a final environmental impact statement, that sets in motion a review period of at least 30 days before a record of decision -- essentially a mine's permit -- can be issued," Scheyder explains. "BLM also published an opinion on how a rare flower at the mine site can best be protected."

The site is home to Tiehm's buckwheat flower, "which is found nowhere else on the planet and was declared an endangered species in 2022," Scheyder reports. "The Center for Biological Diversity and some other conservation groups thus oppose ioneer's project." Patrick Donnelly of CBD called Tiehm's buckwheat flower a "linchpin of the local ecosystem, harboring a highly diverse pollinator community."

It's hoped the mine's lithium production can help the U.S. combat Chinese metal production. Scheyder writes, "The U.S. Geological Survey has labeled lithium a critical mineral vital for the U.S. economy and national security. The proposed mine, roughly 225 miles north of Las Vegas, contains enough lithium to power roughly 370,000 EVs each year."

After years of negotiating, California has found a way to connect renewable energy sources with their stressed grid

A new agreement in California has brought energy stakeholders together to help the state's taxed grid.

"For years, utilities have grappled with how to handle the ever-growing number of solar and battery systems trying to connect to the lower-voltage grids that deliver power to customers," reports Jeff St. John of Canary Media. "But distributed solar and battery resources can also be enormous assets: By holding back power when the grid doesn't need it and then sharing their extra power during periods of high demand, they can help alleviate grid strains and lower the cost of keeping the grid running for everyone."

The agreement between California regulators, utilities and clean-energy proponents has taken "nearly four years to hash out," St. John reports. "But in mid-March, the California Public Utilities Commission approved new interconnection rules that take into account how, with the right structures in place, solar and solar-plus-battery systems can be more help than hazard to California's overworked grid."

CPUC's new policy allows solar and battery projects to "modulate how much power they send to the grid with the help of either solar inverters whose power-control systems can reduce power output from moment to moment or batteries that can soak up excess solar power and inject it back into the grid later," St. John explains. 

Solving grid-interconnection conflicts is a nationwide challenge. 

St. John rreports, "Utilities have very good reasons to take a conservative, safety-first approach to interconnection. After all, they're responsible for keeping grids safe and reliable — and distributed energy resources represent potential disruptions to those grids that utilities can't directly control."
