Starlink’s Direct to Cell satellites complete first post on X

Posted by in categories: Elon Musk, engineering, internet, satellites

SpaceX recently tested Starlink’s Direct to Cell satellites and posted on Elon Musk’s X platform.

The test X post simply said: “This post was sent through a SpaceX Direct to Cell satellite.”

SpaceX’s Director of Satellite Engineering provided more information about the X post. He revealed that the post was made under the cover of trees in a small valley in the Santa Cruz Mountains.

Scientists Find Link Between ADHD, Depression and Hypersexuality

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

Although the interplay between sex and mental health is well-studied, a new study suggests there may be a complex correlation between seemingly disparate disorders.

In a new paper published in the Journal of Affective Disorders Reports, a group of Italian psychology researchers say they’ve found a correlation between attention-deficit/hyperactivity disorder (ADHD), depressive symptoms, hypomania (the clinical term for “mania” or high energy) and hypersexuality, or an intense preoccupation with sexual thoughts and acts — and that people who experience these sets of symptoms may use sex as a sort of “self-medication.”

Study coauthors Giacomo Ciocca, a sexual psychology assistant professor at Rome’s Sapienza University, and Davide Doroldi, a clinical psychologist, told PsyPost that they were inspired to look into the possible link after observing higher rates of hypersexuality among people with ADHD.

Nutrients Direct Intestinal Stem Cell Function and Affect Aging

Posted by in categories: biotech/medical, life extension

The capacity of intestinal stem cells to maintain cellular balance in the gut decreases upon ageing. Researchers at the University of Helsinki have discovered a new mechanism of action between the nutrient adaptation of intestinal stem cells and ageing. The finding may make a difference when seeking ways to maintain the functional capacity of the ageing gut.

The cellular balance of the intestine is carefully regulated, and it is influenced, among other things, by nutrition: ample nutrition increases the total number of cells in the gut, whereas fasting decreases their number.

The relative number of different types of cells also changes according to nutrient status.

TSMC’s new fab in Japan built in 2 years: 24-hour work days, site is called ‘Nightless Castle’

Posted by in category: government

The two years flew past, and now the facility is ready to begin mass production later this year, with TSMC tapping Sony’s assistance to get the plant operational in Japan. The new Kumamoto fab plant has been dubbed “Nightless Castle” as there were workers there on 24-hour shifts, which is how the new TSMC plant was built in just two years, with plants regularly taking three or more years to get up and running.

Sony is an investor and a customer for TSMC’s new plant in Japan; with the new fab plant getting up and running so quickly in Japan, that wouldn’t necessarily be done in other countries. Why? TSMC had efficient government support, strict construction timetables, and a low-cost workforce that was flooding the site and then working 24 hours a day, 7 days a week.

Crew Preps for Spacewalk, Scans Veins and Evaluates Artificial Gravity Suit

Posted by in categories: biotech/medical, robotics/AI

The Expedition 66 crew continued preparing today for the first of two spacewalks set to begin next week to continue upgrading the International Space Station’s power system. Vein scans were also on Thursday’s schedule helping scientists understand how living in space affects the human body.

NASA Flight Engineers Kayla Barron and Raja Chari are set to switch their U.S. spacesuits to battery power at 8:05 a.m. EDT on Tuesday and spend six-and-a-half hours installing a modification kit on the space station’s Starboard-4 truss structure. The new hardware will enable the upcoming installation of a third roll-out solar array increasing the station’s power output and augmenting the existing solar arrays.

The duo was joined by fellow station astronauts Tom Marshburn of NASA and Matthias Maurer of ESA (European Space Agency) for a spacewalk procedures review and conference with specialists on the ground. Marshburn and Maurer will assist the spacewalkers in and out of their spacesuits, operate the Canadarm2 robotic arm, and monitor their external activities. Mission managers will talk about the spacewalk, as well as a second one planned for March 23, live on the NASA TV app and the website on Monday at 2 p.m. NASA TV begins its live spacewalk broadcast on Tuesday at 6:30 a.m.

Dracula’s Chivito: New Protoplanetary Disk discovered with Pan-STARRS

Posted by in categories: materials, space

A protoplanetary disk is a disk of dense gas and dust, orbiting a newly formed star. It is assumed that planets are born by the gradual accumulation of material in such a structure, therefore discoveries and studies of protoplanetary disks are essential for improving our understanding of planetary formation processes.

Now, a team of astronomers led by Ciprian T. Berghea of the U.S. Naval Observatory (USNO) in Washington, DC, has discovered a new disk of this type that is associated with an infrared source known as IRAS 23077+6707. The finding was made by inspecting the Pan-STARRS data while working on a variability study of active galactic nuclei (AGN) candidates.

Study reveals Eco-friendly way to Generate Power from Waste Wood

Posted by in categories: particle physics, sustainability

A new study by researchers at University of Limerick in Ireland has revealed a sustainable method of efficiently converting waste heat into electricity using Irish wood products, while minimizing costs and environmental impact.

The study, led by researchers at UL in collaboration with colleagues at the University of Valencia, has demonstrated a method of generating electricity using low-grade heat recovered from lignin-derived membranes.

Lignin, typically overlooked, is a sustainable byproduct derived from wood in paper and pulp production. The study shows that these membranes can convert waste heat into electricity by utilizing the movement of charged atoms (ions) within the material.

Jensen Huang says kids shouldn’t learn to code — they should leave it up to AI

Posted by in categories: government, robotics/AI

But this isn’t the first time a tech exec has predicted the death of coding.

At the recent World Government Summit in Dubai, Nvidia CEO Jensen Huang made a counterintuitive break with what he thinks is a long tradition of tech CEOs advising youngsters to learn how to code.

Now there’s a 28,000mAh battery with a phone in it

Posted by in category: mobile phones

Four years after Avenir Telecom announced a phone equipped with a massive 18,000mAh battery, the company is announcing an even more outrageous model.

Four years ago, my then-colleague Vlad brought you news of an 18,000mAh battery with a phone in it.


It won’t necessarily be a good phone.
