Using a new time-based method to control light from an ultrafast laser, researchers have developed a nanoscale 3D printing technique that can fabricate tiny structures 1000 times faster than conventional two-photon lithography (TPL) techniques, without sacrificing resolution.

Despite the high throughput, the new parallelized technique—known as femtosecond projection TPL (FP-TPL)—produces depth resolution of 175 nanometers, which is better than established methods and can fabricate structures with 90-degree overhangs that can’t currently be made. The technique could lead to manufacturing-scale production of bioscaffolds, flexible electronics, electrochemical interfaces, micro-optics, mechanical and optical metamaterials, and other functional micro- and nanostructures.

The work, reported Oct. 3 in the journal Science, was done by researchers from Lawrence Livermore National Laboratory (LLNL) and The Chinese University of Hong Kong. Sourabh Saha, the paper’s lead and corresponding author, is now an assistant professor in the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology.

Space bacteria — they’re tiny, invisible, and potentially harmful; even if no one is sure that they actually exist. But for most of the Space Age, NASA and other agencies have treated the possibility of pathogens from space carefully, both during our exploration of other worlds and because of the havoc they could conceivably wreak on Earth. Nowadays, though, there’s a new factor: Elon Musk.

The billionaire entrepreneur dreams of settling thousands of humans on the planet Mars and, oh yeah, he happens to own a rocket company that is slowly building the capability to do so. Musk and other leaders in the commercial space industry are looking at opening up previously unexplored possibilities — asteroid mining, private space stations, package delivery to the moon’s surface. Laudable as these goals are, they are also forcing governments around the world to rethink their space regulations and consider whether they’re up to these impending challenges.

As ever more players enter the space arena it’s time to make sure that everybody is following the best planetary protection practices. Exploring the universe should happen for the benefit of all, including future generations.

A new study is the first to report evidence that nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin may lessen the adverse effects of air pollution exposure on lung function. The team of researchers from the Columbia Mailman School of Public Health, Harvard Chan School of Public Health, Boston University School of Medicine published their findings in the American Journal of Respiratory and Critical Care Medicine.

The researchers analyzed a subset of data collected from a cohort of 2,280 male veterans from the greater Boston area who were given tests to determine their lung function. The average age of participants was 73 years. The researchers examined the relationship between test results, self-reported NSAID use, and ambient particulate matter (PM) and black carbon in the month preceding the test, while accounting for a variety of factors, including the health status of the subject and whether or not he was a smoker. They found that the use of any NSAID nearly halved of the effect of PM on lung function, with the association consistent across all four weekly air pollution measurements from same-day to 28 days prior to the lung function test.

Because most of the people in the study cohort who took NSAIDs used aspirin, the researchers say the modifying effect they observed was mainly from aspirin, but add that effects of non-aspirin NSAIDs are worthy of further exploration. While the mechanism is unknown, the researchers speculate that NSAIDs mitigate inflammation brought about by air pollution.

A year old, and this video is titled with the “I-word”. But a very interesting talk.

It’s not every day that I get to post a video where I feel like I’m involved with something that may seriously improve and extend lives. I’m so grateful that somehow, I was brought into this process.

The ForbiddenKnowledgeTV newsletter and website attract a large number of physicians and health-practitioner subscribers and it’s been a real joy to make friends with the doctors on my list over the years. One leading physician who first contacted me, way back in August 2011 was Dr. Ron Klatz, Founder-President of the American Academy of Anti-Aging and Regenerative Medicine (A4M).

An international team of researchers recently placed an entire molecule into a state of quantum superposition. This huge breakthrough represents the largest object to ever be observed in such a state – essentially occupying two places at once. And it may just be the eureka moment that defines our species’ far-future technology.

Quantum physics is about as close to a faith-based field of scientific study as there is. It’s not our fault, the universe is infinite and complex and we’ve been here for a relatively short amount of time. It’s excusable that we still don’t understand all the rules and, in lieu of a blueprint, we’re forced to come up with theories to explain the things we don’t know.

If India can continue to develop its urban centres and promote a Silicon Valley spirit of entrepreneurship, it could be in a prime position to achieve global tech hub status. Bengaluru (formerly Bangalore) in the south and Gurgaon in the north are two tech-savvy cities emblematic of India’s rapid urbanization. The country is set to become the largest contributor to the world’s urban population.

India has long branded itself as the world’s leading outsourcing destination for global companies, particularly for those in the technology sector — but in the Fourth Industrial Revolution, the time is ripe for the world’s most populous country to reinvent itself.

There is a burgeoning start-up and innovation culture, as shown by the Global Innovation Index, where India has improved its ranking from 81 to 52 between 2015 and 2019. In addition, the country has improved its reputation in terms of the risk posed to foreign investments and, in 2019, ranked third in the world in terms of attracting investment for technology transactions.

To maintain this momentum, India needs to further improve government regulations to encourage support for technological innovation, train tech talent and incentivize it to stay in the country and continue to improve its risk profile by attracting significant foreign and domestic investment in technology. Provided these favourable conditions can be met, India has unmatched potential to become the world’s next Silicon Valley.
