After signal loss, Voyager 1 reconnected with Earth using retro transmitter not used since 1981

Posted by in categories: energy, space

Voyager 1 reconnected with Earth using a backup transmitter inactive for over 40 years.

NASA’s Voyager 1 probe, the most distant human-made object, briefly lost contact with Earth between Oct. 19 and Oct. 24 due to an unexpected shutdown of its main radio transmitter. This signal loss occurred after a command sent to power one of Voyager’s heaters unintentionally triggered the probe’s fault protection system. As a safeguard, the fault protection system automatically powers down non-essential functions when the spacecraft detects an overdraw of its power supply or other malfunctions. Engineers have since reestablished contact through Voyager 1’s backup S-band transmitter, which hadn’t been used since 1981.

The scientist who tested his revolutionary medicine on his own brain cancer: ‘It seemed worth it to give it a crack’

Posted by in categories: biotech/medical, business, neuroscience

Richard Scolyer was fully engaged in the business of living when he suddenly received a death sentence. A person more alive would be hard to find. As an endurance athlete competing across the globe, he was in peak physical condition. As one of the world’s leading pathologists on melanoma whose pioneering research has saved thousands of lives, he was in demand. At 56, Prof Richard Scolyer was flying along. His life, he says, was “rich”. And then, on the morning of 20 May 2023, he found himself losing consciousness and convulsing on the floor in a hotel room in Poland, panicking and scared.

After this grand mal seizure, he went for an MRI scan at University hospital in Krakow. It found a mass in his temporal lobe. Scolyer knew immediately it had delivered very bad news.

Spike-based dynamic computing with asynchronous sensing-computing neuromorphic chip

Posted by in categories: computing, neuroscience

Mimicking high-level abstraction of the brain to achieve energy advantages is a fundamental issue in neuromorphic computing. Here, the authors fabricate an asynchronous chip and demonstrate a high-accuracy neuromorphic system with power consumption of 0.7mW.

What is the origin of dark energy? Scientists reach possible answer

Posted by in category: cosmology

Astronomers have possibly found evidence that dark energy — associated with accelerating the expansion of our universe — could also be related with the mysterious black holes.

About 70% of our universe roughly comprises of dark energy and is believed to have born after the Big Bang, around 13.8 billion years ago, though the origin of the force remains unclear, according to LiveScience.

Recently, some astronomers proposed a theory that dark energy could have emerged from the core of gigantic dark abyss called the black holes while others disagreed with the theory.

Ice Hunt: How NASA’s Lunar Trailblazer Could Transform Moon Exploration

Posted by in categories: energy, space

While scientists know there’s water on the Moon, its exact locations and forms remain largely unknown. A trailblazing NASA mission will get some answers.

NASA’s Lunar Trailblazer mission, designed to map and study water on the Moon, will employ innovative instruments to explore surface water dynamics and support future lunar colonies by providing vital data on potential water sources that could be converted into oxygen or fuel.

Farming in the Dark: How Electro-Agriculture Outpaces Photosynthesis

Posted by in categories: bioengineering, food, genetics, space, sustainability

Bioengineers propose “electro-agriculture,” a method that replaces photosynthesis with a solar-powered reaction converting CO2 into acetate, potentially reducing U.S. agricultural land needs by 94% and supporting controlled indoor farming.

Initial experiments focus on genetically modified acetate-consuming plants like tomatoes and lettuce, with potential future applications in space agriculture.
