Philip Ball explores the new biology, revealing life to be a far richer, more ingenious affair than we had guessed. There is no unique place to look for an answer to this question: life is a system of many levels—genes, proteins, cells, tissues, and body modules such as the immune system and the nervous system—each with its own rules and principles.

In this talk, discover why some researchers believe that, thanks to incredible scientific advancements, we will be able to regenerate limbs and organs, and perhaps even create new life forms that evolution has never imagined.

Philip Ball is a freelance writer and broadcaster, and was an editor at Nature for more than twenty years. He writes regularly in the scientific and popular media and has written many books on the interactions of the sciences, the arts, and wider culture, including 'H2O: A Biography of Water', 'Bright Earth: The Invention of Colour', 'The Music Instinct', and 'Curiosity: How Science Became Interested in Everything'.

Philip's book 'Critical Mass' won the 2005 Aventis Prize for Science Books. He is also a presenter of Science Stories, the BBC Radio 4 series on the history of science.

Abstract

The Double Asteroid Redirection Test (DART) mission impacted Dimorphos, the satellite of binary near-Earth asteroid (65803) Didymos, on 2022 September 26 UTC. We estimate the changes in the orbital and physical properties of the system due to the impact using ground-based photometric and radar observations, as well as DART camera observations. Under the assumption that Didymos is an oblate spheroid, we estimate that its equatorial and polar radii are 394 ± 11 m and 290 ± 16 m, respectively. We estimate that the DART impact instantaneously changed the along-track velocity of Dimorphos by −2.63 ± 0.06 mm s−1. Initially, after the impact, Dimorphos's orbital period had changed by −32.7 minutes ± 16 s to 11.377 ± 0.004 hr. We find that over the subsequent several weeks the orbital period changed by an additional 34 ± 15 s, eventually stabilizing at 11.3674 ± 0.0004 hr. The total change in the orbital period was −33.25 minutes ±1.5 s. The postimpact orbit exhibits an apsidal precession rate of 6.7 ± 0fdg2 day−1. Under our model, this rate is driven by the oblateness parameter of Didymos, J2, as well as the spherical harmonics coefficients, C20 and C22, of Dimorphos's gravity. Under the assumption that Dimorphos is a triaxial ellipsoid with a uniform density, its C20 and C22 estimates imply axial ratios, a/b and a/c, of about 1.3 and 1.6, respectively. Preimpact images from DART indicate Dimorphos's shape was close to that of an oblate spheroid, and thus our results indicate that the DART impact significantly altered the shape of Dimorphos.

Is there any evidence that this is a consequence of DEI rather than a deeper technical issue?

EDIT: Nevermind.

This makes me wonder, how much lawyering is involved in the development of these tools?

Why would this be flagged / shut down?

Also, what Gemini stuff are you referring to?

I would also love to see more transparency around AI behavior guardrails, but I don't expect that will happen anytime soon. Transparency would make it much easier to circumvent guardrails.

I am not the author.

What are the most serious secure messengers?

Sorry, I can't delete it.

Thanks for sharing this discovery! JWST is just a wonderful space telescope.

"The newly discovered jet stream travels at about 320 miles per hour (515 kilometers per hour), twice the sustained winds of a Category 5 hurricane here on Earth. It is located around 25 miles (40 kilometers) above the clouds, in Jupiter's lower stratosphere."

I wonder what it would be like to experience such a jet stream from a planetary surface or low altitude air craft.

Does Earth's stratosphere ever experience similar conditions? I asked GPTBing...

Q:

"What are the fastest recorded sustained winds in the history of Earth's stratosphere?"

A:

"The fastest recorded sustained winds in the history of Earth's stratosphere are not explicitly mentioned in the sources, making it difficult to provide a definitive answer. However, various snippets provide a range of wind speeds observed in the stratosphere, which can provide a rough idea of how fast these winds can get:

1. Winds in the stratosphere can reach near 60 m/s (approximately 216 km/h or 134 mph) according to Wikipedia (https://en.wikipedia.org/wiki/Stratosphere#:~:text=The%20low...).

2. The highest zonal winds in the stratosphere are around 60-70 m/s (approximately 135-155 mph or 217-249 km/h) at 65-70 km (40-43 miles) above Earth's surface, as per Britannica (https://www.britannica.com/science/climate-meteorology/Winds...).

3. Jet streams, which blow through a layer of the atmosphere called the stratosphere, can reach speeds of up to 480 km/h (298 mph) according to National Geographic (https://www.nationalgeographic.org/encyclopedia/wind/#:~:tex...).

4. Winds in the Southern polar vortex in the stratosphere can reach near 60 m/s (220 km/h; 130 mph) as mentioned on Wikipedia (https://en.wikipedia.org/wiki/Stratosphere#:~:text=Winds%20i...)."

I do not want an upgrade, I really appreciate the minimalism of the Hacker News website.

Abstract

Quantum biological tunnelling for electron transfer is involved in controlling essential functions for life such as cellular respiration and homoeostasis. Understanding and controlling the quantum effects in biology has the potential to modulate biological functions. Here we merge wireless nano-electrochemical tools with cancer cells for control over electron transfer to trigger cancer cell death. Gold bipolar nanoelectrodes functionalized with redox-active cytochrome c and a redox mediator zinc porphyrin are developed as electric-field-stimulating bio-actuators, termed bio-nanoantennae. We show that a remote electrical input regulates electron transport between these redox molecules, which results in quantum biological tunnelling for electron transfer to trigger apoptosis in patient-derived cancer cells in a selective manner. Transcriptomics data show that the electric-field-induced bio-nanoantenna targets the cancer cells in a unique manner, representing electrically induced control of molecular signalling. The work shows the potential of quantum-based medical diagnostics and treatments.

Is anyone buying them?

Who benefits from attacking an astronomical observatory?

on the topic of Google Maps alternatives, does anyone use OsmAnd?

It sounds like you need to sort through your downloads folder. I can relate.

Have you tried reaching out to Box / Microsoft and asking about mandatory metadata? Now I'm curious.

I use "Everything" ( https://www.voidtools.com/ ) if I ever need to find lost files.

When I was in high school, I was lucky to take a Pure Mathematics class taught by Paul Lockhart. What a brilliant teacher...

you dug through today, barbs

Yes, in the sense that they demonstrate proficiency in a skill / subject.

You may not give them any weight, but I'm sure you're aware that many employers do. Sometimes certs are preferred, sometimes they're required.
