A microsporidian impairs Plasmodium falciparum transmission in Anopheles arabiensis mosquitoes

Posted by in category: biotech/medical

A microbe found in mosquitoes that appears to block malaria could be used to control spread of the disease in humans, according to researchers in Kenya and Britain.

In findings published Monday by the journal Nature Communications, the authors describes finding the microbe, Microsporidia MB, in mosquitoes around Lake Victoria in Africa — and that they could not find a single mosquito with the microbe that also had the malaria parasite.


A possible malaria control approach involves the dissemination in mosquitoes of inherited symbiotic microbes to block Plasmodium transmission. However, in the Anopheles gambiae complex, the primary African vectors of malaria, there are limited reports of inherited symbionts that impair transmission. We show that a vertically transmitted microsporidian symbiont (Microsporidia MB) in the An. gambiae complex can impair Plasmodium transmission. Microsporidia MB is present at moderate prevalence in geographically dispersed populations of An. arabiensis in Kenya, localized to the mosquito midgut and ovaries, and is not associated with significant reductions in adult host fecundity or survival. Field-collected Microsporidia MB infected An. arabiensis tested negative for P. falciparum gametocytes and, on experimental infection with P. falciparum, sporozoites aren’t detected in Microsporidia MB infected mosquitoes. As a microbe that impairs Plasmodium transmission that is non-virulent and vertically transmitted, Microsporidia MB could be investigated as a strategy to limit malaria transmission.

Modern farming is harming the planet. Tech-driven permaculture could heal it

Posted by in categories: food, futurism

Nevertheless, its approach is often criticized as too labour-intensive, complex and hard to scale. Several of these issues could be solved with technology, enabling a more widespread use of permaculture as a viable option for future agriculture.

This Solar Panel-Like Device Can Generate Electricity in the Dark

Posted by in categories: solar power, sustainability

But a new invention could allow us to continue generating renewable energy even in the dark, the New York Times reports. Electrical engineer Aaswath Raman, at the University of California in LA, has come up with a device that can harness energy from a dark night sky to power an LED — hinting at a new frontier in renewable energy.

Power of the Dark Side

Raman’s findings were published in the journal Joule today. His device — made from easy-to-find materials including Styrofoam and off-the-shelf aluminum parts — takes advantage of radiative cooling, the process that allows objects to release heat after the Sun sets.

‘I Could Solve Most of Your Problems’: Eric Schmidt’s Pentagon Offensive

Posted by in categories: military, robotics/AI

Mr. Schmidt is pressing forward with a Silicon Valley worldview where advances in software and A.I. are the keys to figuring out almost any issue. While that philosophy has led to social networks that spread disinformation and other unintended consequences, Mr. Schmidt said he was convinced that applying new and relatively untested technology to complex situations — including deadly ones — would make service members more efficient and bolster the United States in its competition with China.


The former Google C.E.O. has reinvented himself as the prime liaison between Silicon Valley and the military-industrial complex.

The U.S. military has been “stuck in software in the 1980s,” said Eric Schmidt, Google’s former chief executive. Credit… Winni Wintermeyer/Redux.

Israeli drones win prize as solution to coronavirus worker shortages

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

The drone-maker won the international award for its autonomous drones which have permitted companies to operate efficiently and flexibly despite the absence of workers around the world. The award was given to Percepto by the US-based company Frost and Sullivan, a business consulting firm involved in market research and analysis, for its ‘technological leadership’ in developing unique docking stations that operate independently without the need for a human operator in close proximity.

Hubble Telescope Turns 30 This Month and Is Celebrating by Showing You a Picture of Space From Your Birthday

Posted by in categories: futurism, space

The Hubble telescope is celebrating a milestone birthday this month, but, rather than celebrate alone, NASA and the European Space Agency (ESA) are making this celebration all about you.

On April 24, 1990, NASA launched the Hubble Space Telescope into orbit, where it has recorded some of the most stunning images of the planets and stars around us, inspiring us all to dream a little bigger.

“Hubble’s seemingly never-ending, breathtaking celestial snapshots provide a visual shorthand for its exemplary scientific achievements,” NASA and the ESA explained in a blog post about the telescope’s birthday. “Unlike any other telescope before it, Hubble has made astronomy relevant, engaging, and accessible for people of all ages. The mission has yielded to date 1.4 million observations and provided data that astronomers around the world have used to write more than 17,000 peer-reviewed scientific publications, making it one of the most prolific space observatories in history. Its rich data archive alone will fuel future astronomy research for generations to come.”
