It turned out that Mars wasn’t as silent as first believed. Instead, there is intense seismic activity on the red planet, which is rumbling and groaning.

Two Fathers One Egg

What will it take for a same-sex couple—two males or two females—to be able to produce a biological child by combining their genomes in the same way that male-female couples do? Just to be clear, we’re not talking about adopting. Nor do we mean one mate fertilizes a donor egg or is fertilized with donated sperm. Those things have long existed. We mean you take two women or two men and make a baby.
And they’ve already done it with two male mice.
“Every great and difficult thing has required a strong sense of optimism,” says editor and author Kevin Kelly, who believes that we have a moral obligation to be optimistic. Tracing humanity’s progress throughout history, he’s observed that a positive outlook helps us solve problems and empowers us to forge a path forward. In this illuminating talk, he shares three reasons for optimism during challenging times, explaining how it can help us become better ancestors and create the world we want to see for ourselves and future generations.

Starship is getting very close to becoming real. Starship just did a 14 engine static fire which is nearly as powerful as the Saturn V that landed people on the moon. A 33 engine static fire should happen within a month.
In addition, NASA just signed up Starship for a third trip to the moon. They have now signed up for one cargo and two crew missions to the moon for a total of over $4 billion. Other customers have signed up with Starship as well.
KENNEDY SPACE CENTER, Fla. — NASA has awarded SpaceX a $1.15 billion contract to develop an upgraded version of its Starship lunar lander and fly a second crewed mission.
NASA announced Nov. 15 it completed a contract modification for what is formally known as Option B of its Human Landing System (HLS) contract with SpaceX. Option B covers upgrades to the Starship lander originally selected for HLS by NASA in April 2021 for $2.9 billion. The option also includes a second crewed demonstration landing mission.
“Continuing our collaborative efforts with SpaceX through Option B furthers our resilient plans for regular crewed transportation to the lunar surface and establishing a long-term human presence under Artemis,” Lisa Watson-Morgan, NASA HLS program manager, said in a statement. “This critical work will help us focus on the development of sustainable, service-based lunar landers anchored to NASA’s requirements for regularly recurring missions to the lunar surface.”
Jeff Bezos says he’ll give most of his money to charity, but will that do much to appease critics of his legacy?
A major vulnerability in a networking technology widely used in critical infrastructures such as spacecraft, aircraft, energy generation systems and industrial control systems was exposed by researchers at the University of Michigan and NASA.
It goes after a network protocol and hardware system called time-triggered ethernet, or TTE, which greatly reduces costs in high-risk settings by allowing mission-critical devices (like flight controls and life support systems) and less important devices (like passenger WiFi or data collection) to coexist on the same network hardware. This blend of devices on a single network arose as part of a push by many industries to reduce network costs and boost efficiency.
That coexistence has been considered safe for more than a decade, predicated on a design that prevented the two types of network traffic from interfering with one another. The team’s attack, called PCspooF, was the first of its kind to break this isolation.
It would usually be cheaper to use e-fuels derived from hydrogen — rather than H2 directly — due to system costs, academic paper explains.
From wearable gadgets to battery separators, the future of sustainable tech is starting to look like a mushroom. A team of researchers from the Institute of Experimental Physics in Linz have completed a proof-of-concept study, testing whether mycelium skin could substitute plastic in the production of soft electronics. The scientists used processed skin from the mushroom Ganoderma Lucidum – a saprophytic fungus native to some parts of Europe and China that grows naturally on dead hardwood.
This works by laying electronic components on the fungal skin through a process called physical vapor deposition, used to produce thin materials. The resulting electronic circuit has high thermal stability and can withstand thousands of bending cycles. The researchers say that combining conventional electronics with the biodegradable material could help reduce waste in the production of wearable electronics and sustainable battery separators, among other uses.
