A little more than two years ago, Dmitry Rogozin, the bellicose former head of Russia's space agency, nearly brought the International Space Station partnership to its knees.

During his tenure as director general of Roscosmos, Rogozin was known for his bombastic social media posts and veiled threats to abandon the space station after Russia's invasion of Ukraine. Russian President Vladimir Putin tersely dismissed Rogozin in July 2022 and replaced him with Yuri Borisov, a former deputy prime minister.

While the clash between Russia and Western governments over the war in Ukraine has not cooled, the threats against the International Space Station (ISS) ended. The program remains one of the few examples of cooperation between the US and Russian governments. Last year, Russia formally extended its commitment to the ISS to at least 2028. NASA and space agencies in Europe, Japan, and Canada have agreed to maintain the space station through 2030.

As power utilities and industrial companies seek to use more renewable energy, the market for grid-scale batteries is expanding rapidly. Alternatives to lithium-ion technology may provide environmental, labor, and safety benefits. And these new chemistries can work in markets like the electric grid and industrial applications that lithium doesn't address well.

“I think the market for longer-duration storage is just now emerging,” said Mark Higgins, chief commercial officer and president of North America at Redflow. “We have a lot of… very rapid scale-up in the types of projects that we’re working on and the size of projects that we’re working on. We’ve deployed about 270 projects around the world. Most of them have been small off-grid or remote-grid systems. What we’re seeing today is much more grid-connected types of projects.”

“Demand… seems to be increasing every day,” said Giovanni Damato, president of CMBlu Energy. Media projections of growth in this space are huge. “We're really excited about the opportunity to… just be able to play in that space and provide as much capacity as possible.”

If you were looking for a reason to keep a flamethrower around the house, you may have just found one.

This week, the Los Angeles County health department reported that two people were infected with a raccoon parasite that causes severe, frequently fatal, infections of the eyes, organs, and central nervous system. Those who survive are often left with severe neurological outcomes, including blindness, paralysis, loss of coordination, seizures, cognitive impairments, and brain atrophy.

The parasitic roundworm behind the infection, called Baylisascaris procyonis, spreads via eggs in raccoons feces. Adult worms live in the intestines of the masked trash scavengers, and each female worm can produce nearly 200,000 eggs per day. Once in the environment, those eggs can remain infectious for years. They can survive drying out as well as most chemical treatments and disinfectants, including bleach.

One of the miracles of the Apollo Moon landings is that they were televised, live, for all the world to see. This transparency diffused doubts about whether the lunar landings really happened and were watched by billions of people.

However, as remarkable a technical achievement as it was to broadcast from the Moon in 1969, the video was grainy and black and white. As NASA contemplates a return to the Moon as part of the Artemis program, it wants much higher resolution video and communications with its astronauts on the lunar surface.

To that end, NASA announced this week that it had awarded a contract to Houston-based Intuitive Machines for "lunar relay services." Essentially this means Intuitive Machines will be responsible for building a small constellation of satellites around the Moon that will beam data back to Earth from the lunar surface.

A Senate committee on Thursday voted overwhelmingly to hold the wealthy CEO of a failed hospital chain in civil and criminal contempt for rejecting a rare subpoena from the lawmakers.

In July, the Senate Committee on Health, Education, Labor, and Pensions (HELP) subpoenaed Steward Health Care CEO Ralph de la Torre to testify before the lawmakers on the deterioration and eventual bankruptcy of the system, which included more than 30 hospitals across eight states. The resulting dire conditions in the hospitals, described as providing "third-world medicine," allegedly led to the deaths of at least 15 patients and imperiled more than 2,000 others.

The committee, chaired by Senator Bernie Sanders (I-Vt.), highlighted that amid the system's collapse, de la Torre was paid at least $250 million, bought a $40 million yacht, and owned a $15 million luxury fishing boat. Meanwhile, Steward executives jetted around on two private jets collectively worth $95 million.

Since its founding in 1954, high-energy physics laboratory CERN has been a flagship for international scientific collaboration. That commitment has been under strain since the Russian invasion of Ukraine in 2022. CERN decided to cut ties with Moscow late last year over deaths resulting from the country's "unlawful use of force" in the ongoing conflict.

With the existing international cooperation agreements now lapsing, the Geneva-based organization is expected to expel hundreds of scientists on November 30 affiliated with Russian institutions, Nature reports. However, CERN will maintain its links with the Joint Institute for Nuclear Research, an intergovernmental center near Moscow.

CERN was founded in the wake of World War II as a place dedicated to the peaceful pursuit of science. The organization currently has 24 member states and, in 2019 alone, hosted about 12,400 users from institutions in more than 70 countries. Russia has never been a full member of CERN, but collaborations first began in 1955, with hundreds of Russia-affiliated scientists contributing to experiments in the ensuing decades. Now, that 60-year history of collaboration, and Russia's long-standing observer status, is ending. As World Nuclear News reported earlier this year:

Global temperature records go back less than two centuries. But that doesn't mean we have no idea what the world was doing before we started building thermometers. There are various things—tree rings, isotope ratios, and more—that register temperatures in the past. Using these temperature proxies, we've managed to reconstruct thousands of years of our planet's climate.

But going back further is difficult. Fewer proxies get preserved over longer times, and samples get rarer. By the time we go back past a million years, it's difficult to find enough proxies from around the globe and the same time period to reconstruct a global temperature. There are a few exceptions, like the Paleocene-Eocene Thermal Maximum (PETM), a burst of sudden warming about 55 million years ago, but few events that old are nearly as well understood.

Now, researchers have used a combination of proxy records and climate models to reconstruct the Earth's climate for the last half-billion years, providing a global record of temperatures stretching all the way back to near the Cambrian explosion of complex life. The record shows that, with one apparent exception, carbon dioxide and global temperatures have been tightly linked. Which is somewhat surprising, given the other changes the Earth has experienced over this time.

Welcome to Edition 7.12 of the Rocket Report! For once, a week with not all that much launch news. Among the highlights were Eutelsat's surprise announcement of a deal with Mitsubishi Heavy Industries, SpaceX's ongoing war with the FAA, and Europe identifying a straightforward solution to the upper stage problem on Ariane 6's debut launch earlier this summer.

As always, we welcome reader submissions, and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Small launch vehicles still talking a big game. Despite stiff competition from SpaceX rideshare services and some high-profile failures, ventures are still pursuing small launch vehicles that they argue can fill niches in the market, Space News reports. Launch providers speaking at World Space Business Week said they can deliver satellites when and where customers want rather than waiting for the next available rideshare launch from SpaceX.

All at once, India's government has approved plans to develop a new reusable rocket, the centerpiece of an Indian space station, a robotic sample return mission to the Moon, and a science probe to explore Venus.

"Great news for the space sector!" Indian Prime Minister Narendra Modi posted on X. Collectively, the projects authorized by India's union cabinet will cost an estimated $2.7 billion. Most of the funding will go toward the country's space station and a reusable launch vehicle.

If the projects reach their goals, the approvals announced by Modi on Wednesday will put India on a trajectory to become the third-largest space power in the 2030s, after the United States and China. V. Narayanan, director of India's Liquid Propulsion Systems Center, stated this was the objective in a recent presentation, writing that India's space initiatives will catapult the country to a place "among the three important space powers in the world."

The maker of a homeopathic nasal spray with a history of contamination is refusing to recall its product after the Food and Drug Administration once again found evidence of dangerous microbial contamination.

In a warning Thursday, the FDA advised consumers to immediately stop using SnoreStop nasal spray—made by Green Pharmaceuticals—because it may contain microbes that, when sprayed directly into nasal cavities, can cause life-threatening infections. The FDA highlighted the risk to people with compromised immune systems and also children, since SnoreStop is marketed to kids as young as age 5.

According to the regulator, an FDA inspection in April uncovered laboratory test results showing that a batch of SnoreStop contained "significant microbial contamination." But, instead of discarding the batch, FDA inspectors found evidence that Green Pharmaceuticals had repackaged some of the contaminated lot and distributed it as single spray bottles or as part of a starter kit.

Math teacher Ben Orlin writes and draws the (aptly named) blog Math With Drawings and is the author of a new book, Math for English Majors: A Human Take on the Universal Language. To mark its publication, he devised this entertaining accompanying quiz. You can read the Ars interview with Orlin here.

Math, we like to say, is math. It often seems that mathematics is something beyond our control—something unyielding, universal, inhuman.

But is it really?

Galileo once famously described the universe as a great book "written in mathematical language and its characters are triangles, circles, and other geometrical figures." Unfortunately, it's a language that many people outside of math and science simply do not speak, largely because they are flummoxed and/or intimidated by the sheer density of all that strange symbolic notation.

Math teacher extraordinaire Ben Orlin is here to help with his latest book: Math for English Majors: A Human Take on the Universal Language. And just like Orlin's previous outings, it's filled with the author's trademark bad drawings. Bonus: Orlin created a fun personality quiz, which you can take here to find out your mathematical style.

Orlin's first book, Math with Bad Drawings, after his blog of the same name, was published in 2018. It included such highlights as placing a discussion of the correlation coefficient and "Anscombe's Quartet" into the world of Harry Potter and arguing that building the Death Star in the shape of a sphere may not have been the Galactic Empire's wisest move. We declared it "a great, entertaining read for neophytes and math fans alike, because Orlin excels at finding novel ways to connect the math to real-world problems—or in the case of the Death Star, to problems in fictional worlds."

Most living organisms easily surpass machines when it comes to navigating real-world environments and adaptability to changing conditions. One way to bridge that gap is building biohybrid robots that merge synthetic machinery with biological components like animal muscles, bacteria, or plants.

But living muscles are very hard to keep alive in a machine, bacteria have a very short lifespan, and plants tend to react to things a bit slowly, like Ents in The Lord of the Rings. So, a team of scientists at Cornell University went down a different path and built biohybrid robots controlled by fungi, specifically, oyster mushrooms.

Understanding mushrooms’ signals

Robots controlled by fungi, despite giving strong Last of Us vibes, are a good idea on paper. Fungi are very easy to sustain and can live pretty much everywhere, including extreme environments like the Arctic, or even amid nuclear contamination. They're also cheap to culture in large quantities and excel at reacting to environmental cues like exposure to light.

Droughts in the coming decades could be longer than projected by current climate models, a new study published Wednesday in Nature warns.

The international team of scientists examined potential biases that could skew climate models used to make drought projections under Intergovernmental Panel on Climate Change midrange and high emissions scenarios. The researchers corrected for the bias by calibrating those models with observations of the longest annual dry spells between 1998 and 2018.

By the end of this century, they found that the average longest periods of drought could be 10 days longer than previously projected. Trouble spots included North America, Southern Africa, and Madagascar, where the newly calibrated models showed that the increase in the longest annual dry spell could be about twice what the older models predicted.

The supermassive black holes that sit at the center of galaxies aren't just decorative. The intense radiation they emit when feeding helps drive away gas and dust that would otherwise form stars, providing feedback that limits the growth of the galaxy. But their influence may extend beyond the galaxy they inhabit. Many black holes produce jets and, in the case of supermassive versions, these jets can eject material entirely out of the galaxy.

Now, researchers are getting a clearer picture of just how far outside of the galaxy their influence can reach. A new study describes the largest-ever jets observed, extending across a total distance of 23 million light-years (seven megaparsecs). At those distances, the jets could easily send material into other galaxies and across the cosmic web of dark matter that structures the Universe.

Extreme jets

Jets are formed in the complex environment near a black hole. The intense heating of infalling material ionizes and heats it, creating electromagnetic fields that act as a natural particle accelerator. This creates jets of particles that travel at a substantial fraction of the speed of light. These will ultimately slam into nearby material, creating shockwaves that heat and accelerate that, too. Over time, this leads to large-scale, coordinated outflows of material, with the scale of the jet being proportional to a combination of the size of the black hole and the amount of material it is feeding on.

The Hawaiian island of Kauai may not have any spewing lava, but hikers along the magnificent Napali coast have brought their own volcanic action recently, violently hollowing their innards amid the gushing waterfalls and deeply carved valleys.

Between August and early September, at least 50 hikers fell ill with norovirus along the famed Kalalau Trail, which has been closed since September 4 for a deep cleaning. The rugged 11-mile trail runs along the northwest coast of the island, giving adventurers breathtaking views of stunning sea cliffs and Kauai's lush valleys. It's situated just north of Waimea Canyon State Park, also known as the Grand Canyon of the Pacific.

"It’s one of the most beautiful places in the world. I feel really fortunate to be able to be there, and appreciate and respect that land,” one hiker who fell ill in late August told The Washington Post. "My guts exploding all over that land was not what I wanted to do at all."

Axiom Space is facing significant financial headwinds as the company attempts to deliver on two key commercial programs for NASA—the development of a private space station in low-Earth orbit and spacesuits that could one day be worn by astronauts on the Moon.

Forbes reports that Axiom Space, which was founded by billionaire Kam Ghaffarian and NASA executive Mike Suffredini in 2016, has been struggling to raise money to keep its doors open and has had difficulties meeting its payroll dating back to at least early 2023. In addition, the Houston-based company has fallen behind on payments to key suppliers, including Thales Alenia Space for its space station and SpaceX for crewed launches.

"The lack of fresh capital has exacerbated long-standing financial challenges that have grown alongside Axiom’s payroll, which earlier this year was nearly 1,000 employees," the publication reports. "Sources familiar with the company’s operations told Forbes that co-founder and CEO Michael Suffredini, who spent 30 years at NASA, ran Axiom like a big government program instead of the resource-constrained startup it really was. His mandate to staff up to 800 workers by the end of 2022 led to mass hiring so detached from product development needs that new engineers often found themselves with nothing to do."

Vincent van Gogh's most famous painting is The Starry Night (1889), created (along with several other masterpieces) during the artist's stay at an asylum in Arles following his breakdown in December 1888. Where some have seen the swirling vortices of the night sky depicted in Starry Night as a reflection of van Gogh's own inner turmoil, physicists often see a masterful depiction of atmospheric turbulence. According to a new paper published in the journal Physics of Fluids, the illusion of movement in van Gogh's blue sky is also due to the scale of the paint strokes—a second kind of "hidden turbulence" at the microscale that diffuses throughout the entire canvas.

“It reveals a deep and intuitive understanding of natural phenomena,” said co-author Yongxiang Huang of Xiamen University in China. “Van Gogh’s precise representation of turbulence might be from studying the movement of clouds and the atmosphere or an innate sense of how to capture the dynamism of the sky.”

Physicists have long been fascinated by van Gogh's innate feel for turbulence. As previously reported, in a 2014 TED-Ed talk, Natalya St. Clair, a research associate at the Concord Consortium and coauthor of The Art of Mental Calculation, used Starry Night to illuminate the concept of turbulence in a flowing fluid. In particular, she talked about how van Gogh's technique allowed him (and other Impressionist painters) to represent the movement of light across water or in the twinkling of stars. We see this as a kind of shimmering effect, because the eye is more sensitive to changes in the intensity of light (a property called luminance) than to changes in color.

For most people, an extinct species is an abstraction, a set of bones they might have seen on display in a museum. For Gennady Boeskorov, they are things he has interacted with directly, studying their fur, their skin, their internal organs—experiencing these animals much as they existed thousands of years ago. Some of the well-preserved Pleistocene animals he has worked with include the mummified remains of woolly mammoths (Mammuthus primigenius), an extinct form of rabbit (Lepus tanaiticus), and cave lion cubs (Panthera spelaea).

His latest paper also makes it clear that woolly rhinoceroses belong on this list. Boeskorov is a senior researcher at the Diamond and Precious Metals Geology Institute, Siberian Branch of the Russian Academy of Sciences, as well as a professor at the North-Eastern Federal University in Yakutsk. This July, he and his colleagues described the relatively recent discovery of three woolly rhinoceros mummies, one of which is new to science, in a paper published in the journal Doklady Earth Sciences.

Woolly rhinos (Coelodonta antiquitatis) were stocky, long-haired, two-horned denizens that inhabited Eurasia during the Pleistocene, a period that includes the most recent glacial expansion. They coexisted with woolly mammoths, placing second on the list of largest animals in this ecosystem (behind their tusked proboscidean coevals), and shared a similar dense coat of hair to protect against the cold.
