The only way life extension would remain financially out of reach is if we vote ourselves into a dystopia.
Dr David Sinclair explains why aging therapies will be eventually affordable to us in this clip.

A new tool speeds up development of vaccines and other pharmaceutical products by more than 1 million times while minimizing costs.
In search of pharmaceutical agents such as new vaccines, industry will routinely scan thousands of related candidate molecules. A novel technique allows this to take place on the nano scale, minimizing use of materials and energy. The work is published in the journal Nature Chemistry.
More than 40,000 molecules can be synthesized and analyzed within an area smaller than a pinhead. The method, developed through a highly interdisciplinary research effort in Denmark, promises to drastically reduce the amounts of material, energy, and economic cost for pharmaceutical companies.
Russia’s space director Dmitry Rogozin said on Saturday in a tweet that he would halt ties between partners at the ISS and other joint space projects until the sanctions against Moscow were removed. The leader of Roscosmos complained that the aim of the sanctions was to “kill Russian economy and plunge our people into despair and hunger, to get our country on its knees.”
Rogozin also added that the sanctions will ultimately fail, saying that they “won’t succeed in it, but the intentions are clear.” “That’s why I believe that the restoration of normal relations between the partners at the International Space Station (ISS) and other projects is possible only with full and unconditional removal of illegal sanctions,” Rogozin explained.
A suspension of many partnerships

There’s still a long way to go, but it’s an important milestone.
Ten years ago, solar and wind didn’t even make up 1% of our global energy mix. Now, in just a decade, they’ve reached 10%. It may not seem like much, but becoming such a significant part of the global energy mix in such a short time is remarkable — though there’s still a long way to go.
The past couple of years have been horrendous in more ways than one, but that doesn’t mean all is bad in the world. In fact, renewable energy continued its impressive growth, according to research from Ember, a climate and energy think tank.

The majority of commercial chemicals that enter the market in the United States every year have insufficient health and safety data. For pesticides, the U.S. Environmental Protection Agency uses a variety of techniques to fill data gaps in order to evaluate chemical hazard, exposure and risk. Nonetheless, public concern over the potential threat that these chemicals pose has grown in recent years, along with the realization that traditional animal-testing methods are not pragmatic by means of speed, economics or ethics. Now, researchers at the George Washington University have developed a new computational approach to rapidly screen pesticides for safety, performance and how long they will endure in the environment. Moreover, and most importantly, the new approach will aid in the design of next-generation molecules to develop safer pesticides.
“In many ways, our tool mimics computational drug discovery, in which vast libraries of chemical compounds are screened for their efficacy and then tweaked to make them even more potent against specific therapeutic targets,” Jakub Kostal, an assistant professor of chemistry at GW and principal investigator on the project, said. “Similarly, we use our systems-based approach to modify pesticides to make them less toxic and more degradable, while, at the same time, making sure they retain good performance. It’s a powerful tool for both industry and regulatory agencies that can help design new, safer analogs of existing commercial agrochemicals, and so protect human life, the environment and industry’s bottom line.”
Using their model, the team analyzed 700 pesticides from the EPA’s pesticide registry. The model considered a pesticide’s likely persistence or degradation in the environment over time, its safety, and how well it performed at killing, repelling or controlling the target problem.
Even before Russia invaded Ukraine, the fuel that runs the global economy was in short supply.
Now some analysts say there could be spot shortages of diesel fuel and prices may stay elevated, even if oil and gasoline decline.
Those higher diesel fuel prices are also stoking inflation.
On top of the environmental concerns, Japan has an added motivation for this push towards automation —its aging population and concurrent low birth rates mean its workforce is rapidly shrinking, and the implications for the country’s economy aren’t good.
Thus it behooves the Japanese to automate as many job functions as they can (and the rest of the world likely won’t be far behind, though they won’t have quite the same impetus). According to the Nippon Foundation, more than half of Japanese ship crew members are over the age of 50.
In partnership with Misui OSK Lines Ltd., the foundation recently completed two tests of autonomous ships. The first was a 313-foot container ship called the Mikage, which sailed 161 nautical miles from Tsuruga Port, north of Kyoto, to Sakai Port near Osaka. Upon reaching its destination port the ship was even able to steer itself into its designated bay, with drones dropping its mooring line.
With the onset of warmer temperatures, winter canola is breaking dormancy and army cutworms are now present in fields across Kansas. Significant army cutworm pressure has been observed in fields northwest of Caldwell in Sumner County.
Army cutworms feed aggressively and significant damage can occur in a short period of time. Smaller plants are most susceptible. The larvae feed on the leaf tissue, leaving the plants with a fed-on appearance (Figure 2). When minor feeding is observed, you may find leaves severed from the plant and laying on the soil surface. Where infestations are high, army cutworms will remove all leaf tissue, leaving only the base of the stem (Figure 3).
The economic threshold for chemical control is 1–2 cutworms per foot of row. Army cutworms behave nocturnally and typically spend the daylight hours below ground. When scouting, it is critical to dig in the soil around individual canola plants to find the larvae. However, it is not unusual to find army cutworm above ground when populations are high (Figure 1). The larvae are greenish-gray and often curl up into a C-shape.
The installations of photovoltaic (PV) solar modules are growing extremely fast. As a result of the increase, the volume of discarded solar modules that end up on the recycling market annually will grow at the same rate in the near future. Currently, the aluminum, glass, and copper of the discarded modules are reprocessed; however, the silicon solar cells are not.
Now, researchers from the Fraunhofer Center for Silicon Photovoltaics CSP and the Fraunhofer Institute for Solar Energy Systems ISE, together with the largest German recycling company for PV modules, Reiling GmbH & Co. KG, have built new PERC solar cells with 100% crystalline silicon recycled from end-of-life photovoltaic panels.
The team has developed a process for recovering the silicon material with funding from the German Federal Ministry for Economic Affairs and Climate BMWK. The technique is claimed to recycle silicon from different types of crystalline silicon PV modules, regardless of manufacturer and origin.
