Aircrafts transport people, ship goods, and perform military operations, but the petroleum-based fuels that power them are in short supply. In research published on June 30 in the journal Joule, researchers at the Lawrence Berkeley Lab have found a way to generate an alternative jet fuel by harvesting an unusual carbon molecule produced by the metabolic process of bacteria commonly found in soil.

"In chemistry, everything that requires energy to make will release energy when it's broken. When petroleum jet fuel is ignited, it releases a tremendous amount of energy, and the scientists at the Keasling Lab at the Lawrence Berkeley Laboratory thought there must be a way to replicate this without waiting millions of years for new fossil fuels to form,” said lead author Pablo Cruz-Morales, a microbiologist at DTU Biosustain, part of the Technical University of Denmark.

The idea was born years ago, when Jay Keasling, a chemical engineer at University of California, Berkeley, approached Cruz-Morales, who was a postdoc in his lab at the time, to see if he could synthesize a tricky molecule that has the potential to produce a lot of energy. "Keasling told me: it's going to be an explosive idea," according to Cruz-Morales. The molecule that Keasling wanted to recreate was called Jawsamycin, created by the common bacteria streptomyces, an organism that Cruz-Morales had worked with in the past.

"The recipe already exists in nature," says Cruz-Morales. The jagged molecule is produced by native metabolism of the bacteria as they munch away on glucose. "As they eat sugar or amino acids, they break them down and convert them into building blocks for carbon-to-carbon bonds," he said.

"You make fat in your body in the same way, with the same chemistry, but this bacterial process has some very interesting twists. These twists, which give the molecules their explosive properties, are the incorporation of cyclopropane rings -rings of three carbon atoms arranged in a triangular shape," he added. After careful analysis, the team determined that the enzymes that were responsible for the construction of these high-energy cyclopropane molecules were polyketide synthases.

"Polyketide synthases are the ultimate biological tool to make organic chemistry," says Cruz-Morales.

Cruz-Morales explains that the fuel produced by the bacteria would work a lot like biodiesel. It would need to be treated so that it could ignite at a lower temperature than the temperature needed to burn a fatty acid, but when ignited, it would be powerful enough to send a rocket into space.

"If we can make this fuel with biology there's no excuses to make it with oil. It opens the possibility of making it sustainable," says Cruz-Morales.

In the future, Cruz-Morales hopes that he and the team of Department of Energy researchers who worked on the project will be able to scale up this process so that their alternative fuel could actually be used in aircrafts.

"You can see this as a preparation for the moment because we are going to run out of fossil fuels, and there's going to be a point, not far from now, when we will need alternative solutions," Cruz-Morales explained.

Research Reveals Decades-Long Silverpit Crater Triggered by Tsunami 40 Million Years Ago

A long-running dispute about the origin of a North Sea crater has finally been settled, as new research finds a massive asteroid hit the water and triggered a towering tsunami millions of years ago.

Scientists have found that the Silverpit Crater – which lies around 700 meters beneath the southern North Sea seabed, roughly 80 miles off the coast of Yorkshire – was formed when an asteroid or comet struck the region roughly 43 to 46 million years ago, sparking a 330 feet tsunami.

Since geologists first identified the formation in 2002, the 3km-wide crater and its surrounding ring of circular faults spanning about 20 km have sparked intense debate, according to The Independent.

But researchers say their new study marks the clearest evidence yet that the structure is one of Earth’s rare impact craters.

This confirmation places it in the same category as well-known structures such as the Chicxulub Crater in Mexico, which is linked to the dinosaur mass extinction.

The team used computer modelling and analyzed newly available seismic imaging and microscopic geological samples taken from beneath the seabed.

Dr. Uisdean Nicholson, a sedimentologist in Heriot-Watt University’s School of Energy, Geoscience, Infrastructure and Society, who led the investigation, said: “New seismic imaging has given us an unprecedented look at the crater.”

He said samples from an oil well in the area also revealed rare ‘shocked’ quartz and feldspar crystals at the same depth as the crater floor.

“We were exceptionally lucky to find these – a real ‘needle-in-a-haystack’ effort. These prove the impact crater hypothesis beyond doubt, because they have a fabric that can only be created by extreme shock pressures,” said Nicholson.

The scientists say these microscopic minerals form only under the extreme pressures generated during asteroid impacts, providing strong confirmation of the event.

Early research proposed that the feature was created by a high-speed asteroid impact. Supporters of that idea pointed to its round shape, central peak, and surrounding concentric faults, which are often seen in known impact craters.

But other scientists suggested different explanations. Some proposed that underground salt movement distorted the rock layers and created the structure.

Others argued that volcanic activity may have caused the seabed to collapse.

In 2009, geologists even voted on the issue. According to a report in the December 2009 issue of Geoscientist magazine, most participants rejected the asteroid impact explanation at the time.

The latest findings, published in the journal Nature Communications and funded by the Natural Environment Research Council (NERC), now appear to overturn that conclusion.

Dr. Nicholson said: “Our evidence shows that a 160-meter-wide asteroid hit the seabed at a low angle from the west.”

“Within minutes, it created a 1.5 km high curtain of rock and water that then collapsed into the sea, creating a tsunami over 100 meters high.”

The impact would have produced a violent explosion at the seafloor and sent enormous waves spreading across the region.

Professor Gareth Collins, of Imperial College London, who attended the 2009 debate about the crater’s origin and contributed to the new research, said the researchers have “finally found the silver bullet” to end the debate.

He said: “I always thought that the impact hypothesis was the simplest explanation and most consistent with the observations.”

“It is very rewarding to have finally found the silver bullet. We can now get on with the exciting job of using the amazing new data to learn more about how impacts shape planets below the surface, which is really hard to do on other planets,” Collins added.

Dr. Nicholson also expressed his excitement about using the new findings for further research into asteroids.

“Silverpit is a rare and exceptionally preserved hypervelocity impact crater,” he said.

“These are rare because the Earth is such a dynamic planet – plate tectonics and erosion destroy almost all traces of most of these events.”

The Sansevero Chapel Museum in Naples will allow dozens of visually impaired visitors to take part in a rare tactile experience, letting them touch celebrated works of art including the Veiled Christ, which is widely regarded as one of the most striking masterpieces in the history of sculpture.

On March 17, the museum will host an initiative called La meraviglia a portata di mano – Wonder within reach – organized in partnership with the Italian Union of the Blind and Visually Impaired of Naples, offering about 80 blind and partially sighted visitors a chance to encounter the marble masterpieces.

According to The Guardian, visitors will be guided through the chapel by guides who are also visually impaired in a program designed to place accessibility at the center of the museum experience.

The protective barrier surrounding the sculptures will be removed, allowing participants, wearing latex gloves, to explore by touch the intricate marble surface of the sculptures including Giuseppe Sanmartino’s Veiled Christ, which depicts Jesus covered by a transparent shroud made from the same block as the statue. The tactile route will also extend to the reliefs at the feet of the sculptures La Pudicizia and Il Disinganno.

Chiara Locovardi, a guide, told the state agency Ansa: “The veil covering Christ is extraordinary. It’s impossible to understand how Sanmartino managed to create it. The veil defies explanation – for those who can see and for those who cannot. When you touch it, you can feel the veins pulsing beneath.”

“This initiative forms part of our wider program to create a cultural space that is inclusive and accessible through dedicated pathways and tools tailored to the different needs of museum visitors,” Maria Alessandra Masucci, the president of the Sansevero Chapel Museum, said.

All but two of Austria’s 96 glaciers have retreated over the last two years, monitors in the Alpine country reported Friday, saying the “dramatic development” highlights the impact of climate change.

The latest report from the Austrian Alpine Club shows the Alpeiner Ferner in the western Tyrol region and Stubacher Sonnblickkees in Salzburg to the east are facing the greatest loss, each with a retreat of more than 100 meters (about 330 feet). The average retreat was more than 20 meters (65 feet).

“The disintegration of the glacier tongue is also progressing at the Pasterze, Austria’s largest glacier, making the consequences of climate change visible,” the club said in the report covering 2024 and 2025.

The report, it added, “confirms once again the long-term trend: Glaciers in Austria continue to shrink significantly in length, area, and volume.”

The retreat of glaciers in Europe has vast implications for drinking water, power generation, agriculture, infrastructure, recreational activities, the Alpine landscape and more.

Neighboring Switzerland, which is home to the most glaciers in Europe, has noted a similar retreat in its glaciers in recent years, a trend that has been reported around the world.

Poor weather conditions including low snowfall, warm temperatures including an exceptionally hot June last year — nearly 5 degrees Celsius (9 degrees Fahrenheit) above the average — have contributed to the retreat, The Associated Press quoted the club as saying.

“The glaciers are melting — and with every new report, the urgency grows,” club vice president Nicole Slupetzky said. “It’s no longer a question of whether we can still save the glaciers in their old form; it’s about mitigating the consequences for ourselves.”

Such changes in the Alps should serve as a “wake-up call” for policymakers and the public in its behavior, the club said.

It said the current figure was lower than during the previous two years, but still ranks as the eight-largest retreat in the 135 years of measurements.
