Why did scientists name these new frogs after Star Trek characters?
What sound does a frog make? If you said “croak” or “ribbit” or even “bonk” like the Australian pobblebonk frog, you’d be right. And now, thanks to new research, “Star Trek whistle” is also a correct answer!
Seven newly discovered species of frogs in Madagascar have been named for their unique calls, some of which are similar to whistle-like sound effects used in Star Trek: the “boatswain whistle” and “tricorder” device.
“That’s why we named the frogs after Kirk, Picard, Sisko, Janeway, Archer, Burnham, and Pike – 7 of the most iconic captains from the sci-fi series,” says Miguel Vences of the Technische Universität Braunschweig, Germany, who led the research. (snip-MORE)

“Stellar volcano” captured in dramatic Hubble images
https://players.brightcove.net/5483960636001/default_default/index.html?videoId=6363356718112 (video on the page; it wouldn’t embed.)
Dramatic and colourful close-ups from NASA’s Hubble Space Telescope show a binary system of rambunctious stars. See the high-resolution image here.
The system is called R Aquarii. The primary star is an aging red giant more than 400 times heavier than our Sun. Its companion is a burned-out white dwarf.
The red giant pulsates, changes temperature, and varies in brightness by a factor of 750 times over a roughly 390-day period. At its peak the star is nearly 5,000 times brighter than our Sun.
Meanwhile, the white dwarf dances around the red giant. It orbits the giant star every 44 years.
When the white dwarf gets closest to the red giant, its gravity pulls hydrogen gas off the red giant. The material accumulates around the dwarf star and undergoes nuclear fusion. The result is an explosion akin to an enormous nuclear bomb.
Filaments shoot from the dwarf star’s core like a geyser, forming loops and trails of plasma traveling at more than 1.6 million km per hour. (snip-MORE)

Confirmed: The Sun has reached solar maximum
Representatives from NASA, the National Oceanic and Atmospheric Administration (NOAA) and the international Solar Cycle Prediction panel met on Tuesday and announced that the Sun has reached its solar maximum.
The solar cycle is 11 years. At the height of the cycle, the Sun’s magnetic poles flip and its activity intensifies.
“During solar maximum, the number of sunspots, and therefore, the amount of solar activity, increases,” says Jamie Favors, the director of NASA’s Space Weather Program. “This increase in activity provides an exciting opportunity to learn about our closest star –but also causes real effects at Earth and throughout our solar system.”
Increased solar activity can affect satellites and astronauts in space, as well as communications and navigation systems. (snip-MORE)
Space-made next-gen optic fibres touch back down to Earth
October 8, 2024 Imma Perfetto
Next-generation optical fibre manufactured in microgravity aboard the International Space Station has been returned safely to Earth.
Scientists at Adelaide University in South Australia are now comparing the fibres to otherwise identical Earth-made counterparts to confirm whether the space-made product is superior.
It’s thought likely that it is, but the results won’t be known for a couple of months.
The research has already delivered some interesting results: “Seven of the draws went beyond 700 meters, showcasing that it is possible to produce commercial lengths of fibre in space,” says Rob Loughan, CEO of the company that designed the fibre drawing device, Flawless Photonics.
“The longest draw went above 1,141 meters, setting a record for the longest fibre manufactured in space.”
The fibres were made of ZBLAN glass, a substance which has the potential to transmit light 20 times further than traditional silica-based fibre-optic cables.
In an optical fibre, light becomes dimmer and dimmer as it travels along the fibre. Therefore, for example, submarine fibre optics cables require amplifiers about every 100km to boost the light signal to allow it to be transmitted over long distances.
A ZBLAN optical fibre could increase distances between amplifiers, from every 100 km for silica fibres to every 2,000 km.
But this isn’t feasible yet. In practice, ZBLAN fibres perform about 10 times worse than the best silica fibres because the fabrication process introduces defects and impurities, which lower its efficiency at transmitting light.
Professor Heike Ebendorff-Heidepriem, and her team at the University of Adelaide’s Australian National Fabrication Facility’s (ANFF) are trying to solve the problem of enhanced impurities and defects in current ZBLAN glass fibres.
“The purity of the glass depends on the purity of the raw material, and it is challenging to make highly pure solid raw materials,” says Ebendorff-Heidepriem. The team is trying to completely remove one of the main reasons the defects form: gravity.
“Gravity here on Earth causes convection … If you heat up something on a hot plate, the liquid is hot at the bottom. That makes the density of the liquid at the bottom become lower, which moves this portion of the liquid up, at the top the liquid becomes cooler, making the density higher, therefore gravity pulls it down, and so on” she explains.
Ebendorff-Heidepriem partnered with Flawless Photonics which designed and operates a fibre drawing device that squeezed all the necessary technology into a 0.8m-long box for the ISS.
In June, the more than 11km of fibre returned to Earth, intact. Now, work is underway at the University of Adelaide and at 5 other organisations around the world to determine how much of an impact gravity has on ZBLAN’s ability to transmit light. They are hoping to complete their analysis by December this year.
“We will see: is it better? Is it worse? Is it the same? And no matter what result we get, I think the biggest outcome is already achieved – we can make commercial lengths of optical fibres in space.”

Pertinent To Many Interests, Especially Those Who Feel Marginalized
Kerry Washington Throws Her Support Behind Black-Owned Alternative to MAGA Elon Musk’s Twitter/X
Washington is just one celeb putting her star power behind a Black-owned alternative to the popular social media platform
One of the most disturbing things about billionaire tech leader Elon Musk’s insistence on backing Donald Trump’s presidential campaign is that he’s the CEO of X, the massive social media platform which reported more than 170 million daily active users worldwide on its mobile app in February 2024.
Considering many of X’s Black users — who have made Black Twitter a thing of legend over the years — don’t believe that Trump has our best interests at heart, some have attempted to create other digital spaces for us to shed that X business, and they’re being helped by the likes of Kerry Washington.
Washington is throwing a major investment into SPILL, a Black-owned Twitter alternative created by Alphonzo Terrell, one of the nearly 4,000 employees laid off from the social media platform formerly known as Twitter when Musk acquired the company in November 2022 for $44 billion.
Rather than sulking over his job loss, Terrell linked with friend and former co-worker DeVaris Brown to formulate a plan to make something for us, by us.
“I called [Brown] and I said, ‘I think it’s time to build and if we do this together, I think this can be really successful,’” Terrell told CNN in a September 2022 interview.
Since its 2022 launch, SPILL has grown its customer base to more than 200,000 users. One of the most unique features of the app is SPILL Spades, a live, multiplayer Spades game the company says keeps users engaged for an average of 30 minutes.
In addition to her financial contribution, Washington has hosted live conversations on the platform known as “Tea Parties.” The actress says she’s proud to support a platform in which underrepresented groups are top of mind.
“In a digital world where marginalized groups, especially Black, Brown, and LGBTQIA folks, rarely feel prioritized, SPILL stands out,” Washington said in a statement. “I’m proud to be part of this community as both a user and an investor.”
Terrell says as the company keeps looking for ways to stand out, he is confident SPILL will make a big splash in the social media space.

Some sloths among animals unable to adapt to rapid climate change
A new study warns that sloths living in high-altitude rainforests of South and Central America could face extinction if temperatures there continue to rise according to climatic predictions.
The research, published in PeerJ Life & Environment, suggests that some sloths’ restricted ability to migrate to cooler regions and limited metabolic flexibility make them particularly vulnerable to climate change.
“Sloths are inherently limited by their slow metabolism and unique inability to regulate body temperature effectively, unlike most mammals,” says Dr Rebecca Cliffe, lead researcher of the study from Swansea University and The Sloth Conservation Foundation in the UK.
“Our research shows that sloths, particularly in high-altitude regions, may not be able to survive the significant increases in temperature forecast for 2100.” (snip-MORE)

Structure of important male contraceptive target finally solved
A team at Monash University in Victoria developing a hormone-free, reversible male contraceptive has now figured out the 3D structure of one of their primary therapeutic targets – the P2X1-purinergic receptor (P2X1).
According to Dr Sab Ventura from the Monash Institute of Pharmaceutical Sciences (MIPS), this has been the main stumbling block that has so far hindered the team from progressing the drug discovery program to the next stage.
“Our primary goal is to develop a male contraceptive pill that is not only hormone-free but also bypasses side effects such as long-term irreversible impacts on fertility, making it suitable for young men seeking contraceptive options,” says Ventura.
In previous research in mice, the team showed that simultaneous inactivation of P2X1 and a second protein, α1A-adrenergic receptor, resulted in male infertility.
“Now we know what our therapeutic target looks like, we can generate drugs that can bind to it appropriately, which totally changes the game,” says Ventura. (snip-MORE)

River piracy pushing Mount Everest upwards
Mount Everest is tall. In other news, the sky is blue.
But Everest (also called Chomolungma and Sagarmāthā) is taller than it logically should be – towering 238m above the world’s next highest peak, K2, and more than 250m higher than any of its counterparts in the relatively uniform Himalaya range.
Plus, it’s growing at about 2mm a year, faster than the expected rate for the range.
A team of Chinese and UK scientists have now suggested why this is the case.
The researchers think the culprit is a nearby river which “captured” another river 89,000 years ago, causing erosion that made Everest more buoyant.
They’ve published their findings in Nature Geoscience.
The Himalayan peaks get their extraordinary height from the collision of the Indian and Eurasian tectonic plates, causing the Earth’s crust to thicken and the mountain range to push upwards.
“An interesting river system exists in the Everest region,” says co-author Dr Jin-Gen Dai, from China University of Geosciences.
The team used numerical modelling to see how the river changed over time. They found that, about 89,000 years ago, the Arun river “captured” another nearby river.
This event, referred to as “river piracy”, happens when a river diverts its course and takes up the discharge of another river or stream.
“Our research shows that as the nearby river system cuts deeper, the loss of material is causing the mountain to spring further upwards,” says co-author Adam Smith, a PhD student at University College London, UK.
The team estimates that the river piracy has made Everest between 15 and 50m higher than it would otherwise be.
It’s also made neighbouring peaks, Lhotse and Makalu, unusually tall. These are the 4th and 5th highest mountains in the world, respectively. (snip-MORE)

Science fiction health technology a step closer
It’s not the famous Star Trek tricorder but it’s close: researchers have developed a hand-held scanner that can generate highly detailed 3D images of body parts in almost real time.
The technology can accurately image blood vessels up to 15mm deep in human tissue, which the researchers say could help to diagnose conditions such as cancer, cardiovascular disease, and arthritis.
“We’ve come a long way with photoacoustic imaging in recent years, but there were still barriers to using it in the clinic,” says Paul Beard of University College London (UCL), UK, corresponding author of the new Nature Biomedical Engineering paper.
“The breakthrough in this study is the acceleration in the time it takes to acquire images, which is between 100 and 1,000 times faster than previous scanners.
“This speed avoids motion-induced blurring, providing highly detailed images of a quality that no other scanner can provide. It also means that rather than taking 5 minutes or longer, images can be acquired in real time, making it possible to visualise dynamic physiological events.
“These technical advances make the system suitable for clinical use for the first time, allowing us to look at aspects of human biology and disease that we haven’t been able to before.” (snip-MORE)

Could we hit the “pause button” on human embryo development?
September 27, 2024 Imma Perfetto
The mechanisms that allow some mammals to pause the development of their young inside the womb also seem work in human cells, according to a fascinating new study published in the journal Cell.
Biologists discovered they could induce a dormant state in human cells by decreasing the activity of the mTOR signaling pathway, which they previously showed is a major regulator of this process in mice.
They triggered this dormant state not in human embryos, but in human pluripotent stem cells and stem-cell based models known as blastoids, which mimic the blastocyst stage of embryonic development at about 5 days post-fertilisation. (snip)
Until now it was unclear whether diapause could be triggered in humans.
“The mTOR pathway is a major regulator of growth and developmental progression in mouse embryos,” says co-senior author Aydan Bulut-Karslioglu of the Max Planck Institute for Molecular Genetics in Germany.
“When we treated human stem cells and blastoids with an mTOR inhibitor we observed a developmental delay, which means that human cells can deploy the molecular machinery to elicit a diapause-like response.”
Cells in this dormant state show reduced cell division, slower development and a decreased ability to attach to the uterine lining. The ability to enter this dormant stage seems to be restricted to the blastocyst stage of development. (snip-MORE)
Explosive energy-dense material made from air (with plasma)
September 29, 2024 Ellen Phiddian
Chemists have made an extremely energy-dense, environmentally friendly fuel out of nitrogen.
They’ve done it by employing one of chemistry’s favourite hobbies, bullying nitrogen n (N2) into weird structures. An explosion occurred, but it was a small one.
The Chinese team has successfully made the element adopt a diamond-like structure, called cubic gauche nitrogen (cg-N) and importantly made it without extremely high pressures. In fact, they managed it at standard atmospheric pressure.
They’ve published their triumph in Science Advances.
Pure nitrogen-based molecules have drawn interest from chemists because they can release a tremendous amount of energy when they decompose. (snip-MORE)
Neo-Nazi Telegram Users Panic Amid Crackdown and Arrest of Alleged Leaders of Online Extremist Group
An analysis by ProPublica and FRONTLINE shows a surge in activity on Telegram channels aligned with the Terrorgram Collective, as allies tried to rally support for their comrades in custody and sought to oust users they believed to be federal agents.
It’s a worthy read. Also, if you prefer to listen, click through to listen.
Snippets:
The recent crackdown on the social media platform Telegram has triggered waves of panic among the neo-Nazis who have made the app their headquarters for posting hate and planning violence.
“Shut It Down,” one person posted in a white supremacist chat on Tuesday, hours after Telegram founder Pavel Durov announced he would begin sharing some users’ identifying information with law enforcement.
With over 900 million users around the globe, Telegram has been both revered and reviled for its hands-off approach to moderating posted content. The platform made headlines this summer when French authorities arrested Durov, seeking to hold him responsible for illegal activity that has been conducted or facilitated on the platform — including organized drug trafficking, child pornography and fraud.
Durov has called the charges “misguided.” But he acknowledged that criminals have abused the platform and promised in a Telegram post to “significantly improve things in this regard.” Durov’s announcement marked a considerable policy shift: He said Telegram will now share the IP addresses and phone numbers of users who violate the platform’s rules with authorities “in response to valid legal requests.”
This was the second time in weeks that extremists had called on their brethren to abandon Telegram. The first flurry of panic followed indictments by the Justice Department of two alleged leaders of the Terrorgram Collective, a group of white supremacists accused of inciting others on the platform to commit racist killings. (snip)
An analysis by ProPublica and FRONTLINE, however, shows that despite the wave of early panic, users didn’t initially leave the platform. Instead there was a surge in activity on Terrorgram-aligned channels and chats, as allies of the group tried to rally support for their comrades in custody, railed against the government’s actions and sought to oust users they believed to be federal agents.
Federal prosecutors in the U.S. have charged Dallas Humber and Matthew Allison, two alleged leaders of the Terrorgram Collective, with a slew of felonies including soliciting the murder of government officials on Telegram.
Humber has pleaded (sic) not guilty. She made a brief appearance in federal court in Sacramento, California, on Sept. 13, during which she was denied bail. Humber, shackled and clad in orange-and-white jail garb, said nothing. Allison, who has not yet entered a plea, was arrested in Idaho but will face trial in California.
Attorneys for Humber and Allison did not respond to separate requests for comment.
The two are alleged Accelerationists, a subset of white supremacists intent on accelerating the collapse of today’s liberal democracies and replacing them with all-white ethno-states, according to the indictment.
Through a constellation of linked Telegram channels, the collective distributes books, audio recordings, videos, posters and calendars celebrating white supremacist mass murderers, such as Brenton Tarrant, who in early 2019 stormed two mosques in New Zealand and shot to death 51 Muslim worshippers.
The group explicitly aims to inspire similar attacks, offering would-be terrorists tips and tools for carrying out spectacular acts of violence and sabotage. A now-defunct channel allegedly run by Humber, for example, featured instructions on how to make a vast array of potent explosives. After their arrests, channels allegedly run by Humber and Allison went silent.
But within days of the indictments, an anonymous Telegram user had set up a new channel “dedicated to updates about their situation.” (snip)
Matthew Kriner, managing director of the Accelerationism Research Consortium, said the Terrorgram Collective had already been badly weakened by a string of arrests in the U.S., Europe and Canada over the past two years. “Overall, the arrests of Humber and Allison are likely the final blow to the Terrorgram Collective,” Kriner said.
In the U.S., federal agents this year have arrested at least two individuals who were allegedly inspired by the group. The first was Alexander Lightner, a 26-year-old construction worker who was apprehended in January during a raid on his Florida home. In a series of Telegram posts, Lightner said he planned to commit a racially or ethnically motivated mass killing, according to prosecutors. Court records show that agents found a manual produced by the Terrorgram Collective and a copy of “Mein Kampf” in Lightner’s home.
Lightner has pleaded (sic) not guilty to charges of making online threats and possessing an illegal handgun silencer. His attorney declined to comment. (snip)
In extremist circles, there was more discussion about fleeing Telegram after Durov’s announcement this week. “Time is running out on this sinking ship,” wrote one user. “So we’re ditching Telegram?” asked another.
“Every time we have a success against one of them, they learn, they adapt, they modify,” said Don Robinson, who as an FBI agent conducted infiltration operations against white supremacists. “Extremists can simply pick up and move to a new platform once they are de-platformed for content abuses. This leaves law enforcement and intelligence agencies playing an endless game of Whac-a-Mole to identify where the next threat may be coming from.”
