To plan the future, the PFC represents a step-by-step map of actions, and at every step, this plan moves to the past like a conveyor belt.

This proposes a simple subspace architecture for planning.

A toy environment can clarify it.

Trump and his politics will grind global trading to a limp, and US economy to a halt.

That was the good news. The bad news are the steps taken towards dictatorship.

Hörde igår att den nya "K-pop demonjägarna" har gått från 24 till 12 rutor per sekund, så cirkeln är på något vis sluten.

Såg en klassiker igår. Otroligt hantverk och cool film. Dynamiken i handtecknad film är så annorlunda mot digital 3d animation, otroligt mycket detaljer. Och just denna gjordes i 24 bilder per sekund, dubbelt mot det brukliga på 80-talet.

Swiss glacier collapse buries most of village of Blatten Many homes in Blatten have been flattened after a large chunk of the Birch glacier fell on to the village.

The rules around funding a campaign is different in different countries. Isn't this more about breaking those rules than a cause effect scenario?

Reenactment of pole dancing mixed with medieval bow and arrow, or is it the other way around?

This is so fucking good

This is great reenactment, with focus on average day life.

Thank you for a good read. I sort of agree in general, it's logical that 20 year of experience is better than 20 newbies. It took me a while but what I react to is the glorification of the lonely expert. Teamwork isn't about following one expert, it's about raising the group competence.

What bird is this? Haven't seen this here before

Fantasykören som sjunger på alviska – ”En utomkroppslig upplevelse” Eldandili i Borlänge går hem både hos publiken och bland sångare. Kören, som kombinerar sång på bland annat alviska med cosplay, växer och medlemmarna samlas genom intresset för fantasy.

Diagram illustrating sex determination using amelogenin proteins in tooth enamel. The top shows X and Y chromosomally encoded protein isoforms (AMELX in blue, AMELY in red) with their amino acid sequences highlighted. The middle section displays amelogenin's structural progression from protein to nanospheres to matrix to enamel rods, alongside images of developing tooth structure with labeled components (ameloblasts, enamel, dentin, odontoblasts, pulp). The bottom shows Raman spectroscopy setup with IR laser and detector analyzing a tooth, demonstrating how incident light produces both Rayleigh scattering and Raman scattering from molecular vibrations, resulting in sex-specific spectra shown in a graph (blue and red lines) with male and female symbols. Biological sex determination is essential for analyzing human skeletal remains in archaeology, anthropology, and forensic science. This study investigates whether Raman spectroscopy of intact human dental enamel can be used as a non-destructive method for sex estimation. Orthogonal partial least squares discriminant analysis (OPLS-DA) and logistic regression identified sex-specific spectral characteristics in 88 human teeth from 47 modern individuals (26 females, 21 males). The OPLS-DA model showed excellent performance, with R2Y(cum) = 0.943 and Q2Y(cum) = 0.895. Raman shift wavenumbers at 373, 1182, and 1600 cm−1 were identified as the most reliable discriminators and included in a final logistic regression model. This model achieved an area under the receiver operating characteristic curve (ROC-AUC) of 0.98, a sensitivity of 0.87, and a specificity of 0.94. Our results indicate that Raman spectroscopy can effectively differentiate male and female human dental enamel based on subtle differences in molecular composition—possibly linked to residual differences between AMELX and AMELY-derived proteins.

🧵 Thread: 1️⃣ Fascinating paper by Stewart et al. shows robust method for sex determination using peptides in tooth enamel.

Great potential for #archaeology with fragmentary remains where DNA is degraded. #palaeoproteomics #ZooMS #teammasspec

Participated in my first 1 maj demonstration since like 40 years. I feel the current world situation demands more, but this is a start.

Dr Peter Marks, "Vaccines have been studied very extensively for being potentially associated with autism"

"That theory has been debunked"

"One study in Denmark, over 600,000 children. It shows that if anything, children had a lower rate of autism than unvaccinated children"

Bigger than Texas: the true size of Australia’s devastating floods In outback Queensland, an area four times the size of the UK has been inundated with torrential rain, leaving many cut off or forced to abandon homes

"If the flooding in outback Australia were a country, it would be the world’s 31st largest"

Truly mind-boggling, but just a glimpse of what will become commonplace in the decades to come as our once stable climate falls apart

A week after catastrophic earthquake, focus turns to a growing humanitarian crisis in Myanmar Search teams have pulled more bodies from the ruins of buildings a week after a massive earthquake rocked Myanmar killing more than 3,300 people.

The horrible earthquake has taken more than 3000 lives and Myanmar is now facing a humanitarian crisis.

Myanmar’s military and armed resistance groups have all declared ceasefires to facilitate the flow of humanitarian aid.

How To Build A Thousand-Year-Old Tree | NOEMA A set of experimental techniques and technologies that might seem harmful to trees is actually helping ancient forests survive.

"The goal of veteranization, which is only ever done to young trees, is not to kill them but to leave them living with features like storm damage or damp hollows that would usually not form until much later in life." Matthew Ponsford in @noemamag.com www.noemamag.com/how-to-build...
