NASA back in touch with Voyager 2 after 'interstellar shout'
The Deep Space Network used the highest-power transmitter to send the command (the 100-kw S-band uplink from the Canberra site) and timed it to be sent during the best conditions during the antenna tracking pass in order to maximize possible receipt of the command by the spacecraft.
The probe began returning science and telemetry data at 12:29 am Eastern Time on August 4, "indicating it is operating normally and that it remains on its expected trajectory."

Scientists Regrow Retinal Cells in The Lab Using Nanotechnology
The degeneration is the consequence of damaged retinal pigment cells. Our bodies are unable to grow and replace these cells once they start dying, so scientists have been exploring alternative methods to replace them and the membrane within which they sit.
"In the past, scientists would grow cells on a flat surface, which is not biologically relevant."
"Using these new techniques the cell line has been shown to thrive in the 3D environment provided by the scaffolds."

US Lab Achieves Fusion Ignition in Repeat of Breakthrough Experiment
For a second time since its landmark fusion event in 2022, the US National Ignition Facility (NIF) has squeezed enough energy out of a diamond capsule packed with hydrogen to keep the fusion reaction running. [aka net positive fusion]
Though still far short of producing a reliable, self-sustaining source of power for the community, the repeat achievement is bound to provide vital information on how to improve the technology.

Professor Says He's Invented A Real-life "Freeze Ray"
The problem with being in space or an extremely thin atmosphere is that there's "very little air that can cool," Hopkins explained. Bringing a bunch of coolant isn't a great solution, either, "because that’s going to increase the weight, and you lose efficiency."
A prototype device, as detailed in a new paper his team published in the journal ACS Nano, takes advantage of an unusual physical property of plasma, which is commonly referred to as the "fourth state of matter."
In previous experiments, Hopkins and his colleagues found that a purple jet of plasma cooled a gold-plated surface before heating it up — a puzzling yet replicable result...

Some Meteorites Are Mysteriously Magnetic, And We Finally Know Why
One of the striking things about iron meteorites is that they are often magnetic. The magnetism isn't strong, but it holds information about their origin.
One type of meteorite, known as IVA, is known to be fragments of smaller asteroids. Small asteroids don't have strong magnetic fields, so IVA meteorites shouldn't be magnetic, but many of them are. There's a new study showing how that's possible.

AI recreates clip of Pink Floyd song from recordings of brain activity
An artificial intelligence has created a recognisable cover of a Pink Floyd song by analysing brain activity recorded while people listened to the original. The findings further our understanding of how we perceive sound and could eventually improve devices for people with speech difficulties.

THE HUMAN FUTURE: A Case for Optimism
(720p)
Change is coming. Humanity is entering a turbulent new era, unprecedented in both Earth and Human history. To survive the coming centuries and fulfill our potential as a species, we will have to overcome the biggest challenges we have ever faced, from extreme climate change, to rogue A.I., to the inevitable death of the sun itself.
The headlines make our chances look bleak. But when you look at our history and our tenacity, it's clear that humanity is uniquely empowered to rise to the challenges we face.
If we succeed, our potential is cosmic in scale. Incredible prosperity is within our reach. Being optimistic is not only justified, it's a powerful weapon in the fight for a higher future.

02:50 Part I: Collapse
15:30 Part II: Plateau

Special delivery! Biggest-ever haul of asteroid dust and rock returns to Earth
A saucer-shaped capsule parachuted down gently in the Utah desert today, after a years-long journey through space. Its cargo is a precious collection of rocks and dust from the asteroid Bennu — the first time NASA has ever brought pieces of this type of celestial object back to Earth.
Over the coming days, NASA will fly the bits of Bennu to the Johnson Space Center in Houston, Texas. There, curators will carefully disassemble the container and begin analysing the chemistry and mineralogy of the pristine samples — which might hold clues to the origins of the Solar System.

This is what Earth’s continents will look like in 250 million years
Earth is currently thought to be in the middle of a supercontinent cycle as its present-day continents drift. The last supercontinent, Pangaea, broke apart about 200 million years ago. The next, dubbed Pangaea Ultima, is expected to form at the equator in about 250 million years, as the Atlantic Ocean shrinks and a merged Afro-Eurasian continent crashes into the Americas.

Novel AI Technique Reveals Sample’s Biological or Non-Biological Origin with 90% Accuracy
The search for definitive biosignatures — unambiguous markers of past or present life — is a central goal of paleobiology and astrobiology.
A team of researchers led by the Carnegie Institution for Science has developed a robust method that combines pyrolysis gas-chromatography mass-spectrometry (GC-MS) measurements of a wide variety of terrestrial and extraterrestrial carbonaceous materials with machine-learning-based classification to achieve 90% accuracy in the differentiation between samples of abiotic origins vs. biotic specimens, including highly-degraded, ancient, biologically-derived samples.
