A CLEANER BURNING FUEL

Ethanol is the cleanest, most affordable high-octane fuel on the market. It provides a superior octane boost without the carcinogens associated with other fuel additives.

MORE OCTANE FOR MORE POWER

High-octane fuels like ethanol enhance engine performance by delivering more horsepower and speed. Most vehicles require a minimum octane rating of 87. Ethanol, with an octane rating of 113, helps meet that in modern cars. Ethanol isa cleaner, renewable, and cost-effective alternative to toxic chemicals like lead and MTBE. As a result, ethanol is now blended into 98 percent of motor fuels in the U.S., providing a safe and efficient boost to fuel performance.

MORE OCTANE FOR GREATER EFFICIENCY

Turbocharging forces more fuel and air into a smaller volume, increasing pressure but potentially causing low-octane fuels to ignite prematurely, reducing efficiency and damaging the engine. High-octane fuels, like ethanol, are essential for high-compression, turbocharged, or supercharged engines, ensuring proper ignition timing and delivering more power. Future U.S. fuel efficiency standards may require higher-compression engines, necessitating higher-octane fuels, which ethanol can provide at a lower cost.

In March 2026, tanker rates for Very Large Crude Carriers (VLCCs) leaving the Middle East to Asia were the highest since at least November 2005, when data were first recorded. The price increase followed Iran's closure of the Strait of Hormuz on March 2.

Scientists have developed a breakthrough “superfood” for honeybees by engineering yeast to produce the essential nutrients normally found in pollen. In controlled trials, colonies fed this specially designed diet produced up to 15 times more young, showing a dramatic boost in reproduction and overall health. As climate change and modern agriculture reduce the availability of natural pollen, this innovation could offer a practical way to support struggling bee populations.

A cow named Veronika has stunned scientists by using tools in a flexible and purposeful way. She chooses different ends of a brush depending on the part of her body and adjusts her movements accordingly. This level of tool use is incredibly rare and was previously seen mainly in primates. The finding hints that cows may be much smarter than we assume.

Having both excess belly fat and low muscle mass isn’t just unhealthy—it’s potentially deadly, raising the risk of death by 83%. This condition, called sarcopenic obesity, creates a vicious cycle where fat accelerates muscle breakdown and inflammation. Researchers found it can be identified using simple measurements, not costly medical tests. That means earlier detection—and a real chance to intervene before serious decline sets in.

Using a smartphone with long nails can be frustrating, forcing people to awkwardly tap with their fingertips instead of their nails. Now, researchers are working on a clear nail polish that could change that by turning fingernails into touchscreen-friendly tools. By experimenting with dozens of formulas, they discovered that combining common compounds like taurine and ethanolamine can help nails carry just enough electrical charge for screens to detect a touch.

A sweeping global report finds that migratory freshwater fish are in steep decline, with populations down roughly 81% since 1970. These species depend on long, connected rivers, but dams and human pressures are cutting off their routes. Hundreds of species now need coordinated international protection. Experts say restoring river connectivity is critical to preventing further collapse.

Deepfake X-rays created by AI are now convincing enough to fool both doctors and AI models. In tests, radiologists had limited success identifying fake images, especially when they didn’t know they were being shown. This opens the door to risks like fraudulent medical claims and tampered diagnoses. Experts say stronger safeguards and detection tools are critical as the technology advances.

Long COVID remains a frustrating medical mystery, affecting up to 1 in 10 people long after the initial infection fades. Now, scientists have uncovered a crucial clue hidden deep within the immune system. By analyzing individual immune cells, they identified a distinct molecular state in key white blood cells—especially common in patients who initially had mild or moderate COVID.

Researchers have identified a crucial ion channel, TMEM175, that acts like an overflow valve in the cell’s recycling system. It regulates acidity inside lysosomes, ensuring they function properly. When TMEM175 is faulty, toxic buildup can occur, contributing to diseases like Parkinson’s. This breakthrough reveals a promising new target for future therapies.

By closely monitoring fish throughout their lives, researchers found that simple behaviors in midlife—like movement and sleep—can predict lifespan. Fish that stayed active and slept mostly at night tended to live longer, while those slowing down earlier lived shorter lives. Surprisingly, aging didn’t unfold smoothly but in sudden jumps between stages. The work suggests that tracking daily habits in humans could reveal early clues about how we age.

WASHINGTON, D.C.—Growth Energy, the nation’s largest biofuel trade association, applauded the Trump administration’s decision to grant emergency waivers allowing uninterrupted, nationwide sales of lower-cost E15, a fuel blend made with 15% ethanol that can be used in 96% of cars on the road today. The decision to issue an E15 summer waiver will ensure that consumers will maintain access to a fuel that saves drivers up to 30 cents per gallon.

“We applaud President Trump, EPA Administrator Zeldin, and our Midwestern governors for their support, and for taking swift action to ensure that retailers, refiners, and biofuel producers have the certainty they need to protect consumer access to savings at the pump,” said Growth Energy CEO Emily Skor. “With the conflict in the Middle East and its impact on the global oil marketplace, it’s more important than ever to shield U.S. consumers from volatility with lower-cost, American-made fuel.”

“Now, to bring E15 to new markets and more consumers, it’s vital that Congress act quickly on President Trump’s call for nationwide legislation allowing uninterrupted sales of lower-cost E15. It’s a common-sense solution that doesn’t cost taxpayers a dime. Not only will permanent legislation unlock greater fuel savings across the U.S.—it will deliver an immediate, badly-needed boost to the rural economy.”

EIA is launching three voluntary pilot field studies to evaluate energy consumption in data centers, with web-based pilot surveys in Texas and Washington state as well as in-person interviews in Northern Virginia and Washington, DC.

The United States produced 10 million short tons (MMst) of coke used in steel manufacturing in 2025, a drop of 78% from 1980 when it produced 46 MMst, according to EIA's most recent Annual Coal Report and Quarterly Coal Report. Similarly, we estimate the United States consumed 9.3 MMst of coke in 2025 compared with 41 MMst in 1980, a decline of 77%, by annualizing the first three quarters of data from the most recent Quarterly Coal Report.

Vivid dreams might be doing more than just entertaining your mind at night. Researchers found that immersive dreaming can actually make sleep feel deeper and more refreshing, even when brain activity is high. Surprisingly, people reported their deepest sleep after intense dream experiences, not just during quiet, inactive periods. This suggests dreams may play a key role in helping us feel truly rested.

Snow flies have an unexpected way of surviving freezing temperatures. They produce antifreeze proteins to block ice formation and can even generate their own heat. Scientists also found that their genes are unusually unique, and they feel less cold-related pain than other insects. These combined traits let them stay active in conditions that would freeze most species.

A major discovery reveals that metformin works not just in the body, but in the brain. By switching off a key protein and activating specific neurons, the drug lowers blood sugar through a previously hidden pathway, opening new doors for diabetes treatment.

Deep inside a cave, scientists uncovered fossils from 16 species, including a newfound kākāpō ancestor that may have been able to fly. These remains reveal that New Zealand’s ecosystems were constantly disrupted by volcanic eruptions and rapid climate shifts. Long before humans, waves of extinction and replacement reshaped the islands’ wildlife. It’s a rare window into a missing chapter of natural history.

Scientists have discovered that losing a key protein in small cell lung cancer triggers inflammation that actually helps tumors grow and spread. Even more surprising, it pushes cancer cells into a more aggressive, neuron-like state linked to relapse.
