Dr. Isaac Asimov was a prolific science fiction author, biochemist, and professor. This was recorded in 1982. Asimov was best known for his works of science fiction and for his popular science essays. Born in Russia in 1920 and brought to the United States by his family as a young child, he went on to become one of the most influential figures in the world of speculative fiction. He wrote hundreds of books on a variety of topics, but he’s especially remembered for series like the \.
From the mind of Callum Diggle comes a bleak outlook for humanity, set hundreds of years in the future. The universe of Humanity Lost is one we’d we’d barely recognize, but there is a lot to discover. In today’s video, we’ll discuss a few of the events that led to humanity’s downfall, as well as exploring some of the new forms of life that await us.

Scientists have invented an artificial plant that can simultaneously clean indoor air while generating enough electricity to power a smartphone.
A team from Binghamton University in New York created an artificial leaf “for fun” using five biological solar cells and their photosynthetic bacteria, before realising that the device could be used for practical applications.
A proof-of-concept plant with five artificial leaves was capable of generating electricity and oxygen, while removing CO2 at a far more efficient rate than natural plants.
The team also studied the direct interaction between charged particles in the solar wind as well as plasma around Mercury and BepiColombo itself. This process is complicated by the fact that when the spacecraft is facing the sun, it is heated and cooled, and heavier charged particles called ions can’t be detected because BepiColombo becomes electrically charged and repels them.
However, when BepiColombo slips into the shadow of Mercury, cool ions in a sea of plasma become detectable. This allowed BepiColombo to see ions of the elements oxygen, sodium and potassium around Mercury. The team thinks these particles originated from the surface of the tiny planet and were launched into space by meteorite strikes or solar wind bombardment.
“It’s like we’re suddenly seeing the surface composition ‘exploded’ in 3D through the planet’s very thin atmosphere, known as its exosphere,” MPPE instrument lead Dominique Delcourt, from the Laboratoire de Physique des Plasmas, said in the statement. “It’s really exciting to start seeing the link between the planet’s surface and the plasma environment.”
On October 7, 2024, the XB-1, Boom Supersonic’s groundbreaking supersonic demonstrator, completed its fifth test flight from the Mojave Air & Space Port, reaching a new top speed of Mach 0.69 (324 KIAS) and a maximum altitude of 17,800 feet.
Flown by Chief Test Pilot Tristan “Geppetto” Brandenburg, the aircraft remained airborne for approximately 50 minutes, setting a new record for the program in terms of speed, altitude, and flight duration.

Summary: Scientists have identified how genetic variants influence the risk of neurological and psychiatric disorders, including schizophrenia and autism. Using live neural cells and DNA sequencing, researchers discovered thousands of “non-coding” genetic variants with context-dependent functions, activated during brain development.
These variants act like switches, turning genes on or off depending on cellular pathways. This research offers new insights into the biological mechanisms behind psychiatric disorders and could lead to personalized treatments based on genetic profiles.
