Software offers new way to listen for signals from the stars

Posted by in categories: alien life, information science

The Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS), led by Akshay Suresh, Cornell doctoral candidate in astronomy, is pioneering a search for periodic signals emanating from the core of our galaxy, the Milky Way. The research aims to detect repetitive patterns, a way to search for extraterrestrial intelligence (SETI) within our cosmic neighborhood.

The researchers developed software based on a Fast Folding Algorithm (FFA), an efficient search method offering enhanced sensitivity to periodic sequences of narrow pulses. Their paper, “A 4–8 GHz Galactic Center Search for Periodic Technosignatures,” was published May 30 in The Astronomical Journal.

Pulsars—rapidly rotating that sweep beams of radio energy across the Earth—are natural astrophysical objects that generate periodic signals but humans also use directed periodic transmissions for a variety of applications, including radar. Such signals would be a good way to get someone’s attention across , standing out from the background of non-periodic signals, as well as using much less energy than a transmitter that is broadcasting continuously.

Indian scientists discover gigantic alien planet, 13 times bigger than Jupiter

Posted by in categories: physics, space

An international team of scientists led by Professor Abhijit Chakraborty of the Physical Research Laboratory (PRL) in Ahmedabad identified the densest alien planet, 13 times the size of Jupiter.

This is the third exoplanet identified by PRL scientists. The discovery was detailed in the journal Astronomy & Astrophysics Letters.

Scientists from India, Germany, Switzerland, and the United States utilised the indigenous PRL Advanced Radial-velocity Abu-sky Search spectrograph (PARAS) at Mt. Abu’s Gurushikhar Observatory to precisely determine the planet’s mass. The exoplanet weighs 14 g/cm3.

The first 110-inch 16K TV screen is here to make your projector feel inadequate

Posted by in category: electronics

Chinese display maker BOE has unveiled a truly massive 110-inch 16K TV, putting the hordes of 4K TVs and projectors on the market to shame.

This seismically large prototype packs in a 16K resolution, with four times as many pixels as an 8K screen, and 16 times the pixel count of 4K. It was shown off at SID Display Week 2023 in Los Angeles, to celebrate BOE’s 30-year anniversary with a showcase of cutting-edge resolution far beyond the average television (via Heise.de).

Unveiling a Genetic Breakthrough: Enhancing Cancer-Killing Cells and Extending Lifespan

Posted by in categories: biotech/medical, genetics, life extension

😗😁


In the pursuit of extending healthy human lifespans, scientists have achieved a remarkable breakthrough that marks a significant milestone in the field. Researchers from Taipei Medical University in Taiwan have uncovered a genetic modification in mice that can empower cancer-killing cells, increasing their effectiveness by two to seven times while extending their lifespan by up to 20 percent.

Building upon last year’s groundbreaking study, the scientists have now successfully replicated these extraordinary outcomes in ordinary mice through a single transplant of blood stem cells. The findings, published in the scientific journal Cold Spring Harbor Protocols, hold immense importance, according to Che-Kun James Shen, the lead researcher of the study. He believes that these findings could have profound implications for human health and anticipates that clinical trials could commence as early as the end of this year or next year.

Researchers present an unsupervised learning-based optical fiber imaging system

Posted by in categories: biotech/medical, neuroscience

Fiber-optic imaging methods enable in vivo imaging deep inside hollow organs or tissues that are otherwise inaccessible to free-space optical techniques, playing a vital role in clinical practice and fundamental research, such as endoscopic diagnosis and deep-brain imaging.

Recently, supervised learning-based fiber-optic imaging methods have gained popularity due to their superior performance in recovering high-fidelity images from fiber-delivered degraded images or even scrambled speckle patterns. Despite their success, these methods are fundamentally limited by their requirements for strictly-paired labeling and large training datasets.

The demanding training data requirements result in time-consuming data acquisition, complicated experimental design, and tedious system calibration processes, making it challenging to satisfy practical application needs.
