Cells organize their molecules into distinct functional areas. While textbooks usually refer to membrane-bound organelles such as mitochondria and cell nuclei, recent studies have also revealed organelles without membranes. These include stress granules and proteasome storage granules (PSGs).
Massive runaway stars in the Milky Way: Observational study explores origins and ejection process
Wednesday, January 28th, 2026 04:51 pmResearchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), in collaboration with the Institute of Astrophysics of the Canary Islands (IAC), have led the most extensive observational study to date of runaway massive stars, which includes an analysis of the rotation and binarity of these stars in our galaxy.
Caterpillars hear through tiny body hairs, which could inspire improved microphones
Wednesday, January 28th, 2026 04:47 pmNo ears, no problem. The tobacco hornworm caterpillar, a common garden pest, can actually detect airborne sound via microscopic hairs on its body, according to a team of faculty and graduate students at Binghamton University. The research could have implications for improving microphone technology.
Simple statistical method predicts landslide risk more accurately than classic method
Wednesday, January 28th, 2026 04:43 pmA relatively simple statistical analysis method can more accurately predict the risk of landslides caused by heavy rain, according to a study coordinated by Brazilian researchers affiliated with the Institute of Mathematical and Computer Sciences at the University of São Paulo (ICMC-USP) in São Carlos and the National Institute for Space Research (INPE). The researchers have validated their strategy based on a real event.
Essential oils may provide a natural remedy for antibiotic resistance
Wednesday, January 28th, 2026 04:41 pmThyme, rosemary, and lavender have long been associated with natural medicine. Today, however, these aromatic plants are increasingly being studied by researchers. "In an era of ever-increasing microbial resistance to antibiotics, there is a growing emphasis on the need to introduce antimicrobial products into therapy to which microbes have not yet developed resistance," says Dr. Malwina Brożyna from Wroclaw Medical University. For nearly a decade, she has been researching the properties of essential oils and their therapeutic potential."
AI model forecasts severe thunderstorms 4 hours ahead with higher accuracy
Wednesday, January 28th, 2026 04:32 pmIn a critical advance for climate resilience, researchers from The Hong Kong University of Science and Technology (HKUST) have developed an AI model that can predict dangerous convective storms—including Black Rainstorms, thunderstorms and extreme heavy rainfall like those that have hit Hong Kong—up to four hours before they strike. This world-first technology, developed in collaboration with national meteorological institutions and powered by satellite data and advanced deep diffusion technology, improves forecast accuracy by over 15% at the 48-kilometer spatial scale compared with existing systems. This breakthrough strengthens the overall accuracy of the national weather forecasting system and promises to transform early warning systems for vulnerable communities across Asia.
Framework sets new benchmarks for 3D atom maps in amorphous materials
Wednesday, January 28th, 2026 04:28 pmResearchers at the California NanoSystems Institute at UCLA published a step-by-step framework for determining the three-dimensional positions and elemental identities of atoms in amorphous materials. These solids, such as glass, lack the repeating atomic patterns seen in a crystal. The team analyzed realistically simulated electron-microscope data and tested how each step affected accuracy.
Overlooked threat: Dams trigger temperature-driven disease in iconic salmonid fish
Wednesday, January 28th, 2026 04:25 pmA new study published in Communications Biology reveals a critical, yet previously overlooked, environmental consequence of man-made dams constructed across rivers and streams. By investigating a key indicator species of ecosystem health, the brown trout (Salmo trutta), researchers from the Estonian University of Life Sciences and the Swedish University of Agricultural Sciences demonstrated that small river impoundments significantly elevate water temperatures and drastically increase the pathogenic impact of Proliferative Kidney Disease (PKD).
Tropical feedback loop: Butterfly mimicry patterns evolve faster near the equator
Wednesday, January 28th, 2026 04:20 pmIn the early 1990s, Keith Willmott and a friend, both undergraduate students from the United Kingdom, arrived in Ecuador with impressionable minds and big aspirations. Willmott initially imagined there might be 20 to 30 butterfly species in the region that had yet to be described; once those had been named, writing field guides would be a mere matter of taking a few photos and spelling out where everything lived.
Beyond polymers: New state-of-the-art 3D micro and nanofabrication technique overcomes material limi
Wednesday, January 28th, 2026 04:19 pmBuilding things so small that they are smaller than the width of a human hair was previously achieved by using a method called two-photon polymerization, also known as 2PP—today's state-of-the-art in 3D micro- and nanofabrication. Tiny sculptures such as a miniature replica of the Eiffel Tower or the Taj Mahal made the headlines.
Didn't want to get up this morning. Bed so warm, world so cold. Checked my phone in bed and saw 47 has taken to wearing a glove on his left hand to hide the bruising, like Cosmo Gilt. Yeah, could be because of aspirin use-- I used to get amazing bruises back in my aspirin and codeine days-- but someone cheerfully remarked that the Queen had a similar bruise on her hand when greeting Lettuce Liz, and two days later she was dead. Of course if he's taking aspirin he's less likely to have a stroke, which is unfortunate, but maybe the Big Macs will do for his heart.
Is still freezing out because wind chill. Went out and scraped packed snow off front walkway and a bit of the sidewalk, but there's ice underneath. It comes up if you hack at the right angle but that irritates my touchy neck vertebrae so I couldn't finish. Removed a bit of the snow mountain in front of the bins and the gas meter. Bins aren't going out any time soon and new company is making noises about not taking bagged recycling like the city used to, but the gas reader is coming next week. Mind, the gas co. should just do another estimate this month and cut their losses.
Reading is still Dr. Siri but I wanted a break and some easily understood classical English mystery, so I got a .99 special (and why doesn't this keyboard have a cents sign? I can have £ and € and ¥, but cents, no.) It was very silly and I deleted it from my account so I don't even know what it was called. Then had recourse to a Dr. Priestley, but Rhode has a verbal tick that increasingly grates. Whenever a witness is asked about an event, the answer begins with either 'I'll tell you how it was' or 'It was like this.' Ah well. Back to Dr. Siri.
Dead tree is Flora's Fury to get it off the shelf. I should read at least Flora's Dare to refresh the memory, but Libby doesn't have it and it's non-circulating at the library. Still, the world building is a lot of fun and I'm enjoying it.

Yesterday was very busy for me.
I got a text from MONARCA in the late morning that there were 20 heavily armed iCE agents attempting to gain access to the Dorothy Day facility in downtown Saint Paul. I hopped in my car and headed out, but, as seems to be typical of me, I arrived fifteen minutes too late. I talked with a witness and he told me that the staff locked the doors and demanded a warrant. ICE was forced to leave without abducting anyone. I was joking to a friend that they should send me out to every one of these calls because every one I have ever arrived at, it has either been a false alarm or, as in this case, the ICE agents left empty-handed. I am, apparently, some kind of anti-ICE luck charm. ;-)
So, even though, for me, it wasn't a confrontation, I was still really keyed up afterwards. So, I basically just went directly to my Food Communists and spent three hours packing up groceries for folks sheltering in place/in hiding. The nice thing about my Food Communists is that they are also a homeless/unhoused warming shelter and so they have free meals. I can't forget to eat if I'm at ZCC because someone will tell me to sit and eat at some point, which is good.
Then, at 6 pm yesterday, I signed up for a legal observer training with COPAL. I'll be honest with you all? I have only ever kind of been half-assed trained in this. I was signed up with MONARCA, but I missed the actual training session, and have been relying on notes taken by a friend. So, this seemed like a really good opportunity to get the whole deal. I'd also attended that national training via the ACLU the night before, and, given that my brain is a soupy seive right now, I figure the more times I hear how it's done, the better.
The Observer trainers were expecting 150 people so I walked over. Despite the temperatures, the church sponsoring this event is only five or six blocks away. The place was packed. They actually had Constitutional Observers outside on ICE watch because... I guess because we no longer trust those jackbooted thugs not to terrorize people just trying to learn how to protect their neighbors.
A couple of funny things about the training. First, Minnesotans are still entirely Minnesotan.
The person running the training tried to get us all to introduce ourselves to our seat mates by asking us to ask a stranger "why they were here." Literally the people I sat by in the pew, were like, "I don't even know where else I would be? I am literally worried about our actual neighbor," I was like, "I know. It's kind of a weird question because the answer is: fascism?? Also, why would we sit by and let our neighbors get kidnapped when fifty of us show up to help someone get out of a ditch?" So, that was both good and very awkward because it was clear that a couple of guys just wanted to shrug because Minnesotan men are like "eh? 'Cuz it's the right place to be??"
Second, the trainer kept trying to get us more engaged by having people "popcorn" (which I guess just means shout out as the spirit moves you??) some of the slides and this was... so very Minnesotan. You could tell people hated being asked to do this, but we were all there because we were willing to get out of our comfort zones so people just FORCED themselves to speak up. It was kind of hilarious because the, like "OMG, FINE I WILL SPEAK WITHOUT RAISING MY HAND THIS IS SO PAINFUL I WILL DIE IF I ACCIDENTALLY TALK OVER SOMEONE" was palpable in the air?
But, it was a good meeting and I am now signed up on COPAL as well as MONARCA.
I woke up really sore from all the physical work at the Food Commies, so I have declared today a mental and phsyical rest from the revolution.
Have I read anything? Just the training manual for the constitutional observers. It's been rough!
Plant mothers send molecular 'text messages' to pollen
Wednesday, January 28th, 2026 04:00 pmSmall RNAs are short RNA molecules that help determine which genes in a cell are switched on or off. Until now, it was assumed that the small RNAs necessary for pollen development originate in the pollen itself and in the directly surrounding maternal tissue. However, a new study conducted by the MPI-MP reveals a surprisingly different picture: The crucial signals do not originate in the pollen, but in maternal tissue and can be transported over long distances, for example from the roots.
Changing land use can increase threat of animal‑to‑human disease spread
Wednesday, January 28th, 2026 03:53 pmChanges to land use can directly heighten the risk of diseases spreading from animals to humans, new University of Stirling–led research has shown. The study, led by Dr. Adam Fell of the University's Faculty of Natural Sciences, shows that deforestation, farming, fast-growing cities and fragmented habitats heighten the risk of zoonotic diseases such as COVID-19 and malaria, especially those spread by mosquitoes, rodents and bats.
Proton-trapping MNene transforms ammonia production for food security and economic growth
Wednesday, January 28th, 2026 03:50 pmWith a new electrochemical synthesis via an electrochemical nitrogen reduction reaction (NRR), achieving carbon-free ammonia production is closer to reality through work from Drs. Abdoulaye Djire and Perla Balbuena, chemical engineering professors at Texas A&M University, and graduate students David Kumar and Hao En Lai. A topic outlined in their recent paper published in the Journal of the American Chemical Society introduces NRR, which produces ammonia in a cleaner and simpler way by using renewable electricity.
Cross-border pollution tracking reveals unequal distribution of risk and responsibility
Wednesday, January 28th, 2026 03:43 pmMicroscopic airborne particles known as PM2.5 contribute to 100,000 premature deaths in the United States each year. A new University of Notre Dame study finds that 40% of these deaths can be attributed to pollution that crosses state lines, highlighting the impact of the problem and pinpointing which states are responsible.
Corals sleep like us, but their symbionts never rest
Wednesday, January 28th, 2026 03:40 pmSleep is essential for much of the animal kingdom. During the night, neuron and tissue repair mechanisms are activated to aid recovery from daily activity. This is risky: organisms that sleep are more vulnerable to predators. However, the phenomenon extends from mammals to invertebrates. Nevertheless, until now it was not known whether other, more ancient groups without neurons, such as corals, engage in any kind of nocturnal rest.
