Looking back over years of research into the topic of hybrid systems based on different combinations of solar, wind, hydro and other renewables, an international group of scientists found strong potential for strategies to exploit complementarity between the different sources integrate more intermittent renewables onto regional and national grids. The scientists present a series of conclusions and recommendations that aim to push research in hybrid renewables forward.
A breakthrough skin-gel is showing promising signs in Australian trials, with the ability to halt chronic pain in its tracks, halve healing time and even turn back the clock on ageing skin.
The gel, which is known as RM191A, is believed to be a new class of anti-inflammatory.
It’s a copper-based compound which is applied directly to the skin as a topical.

Researchers from Osaka University propose a concept for next-generation ultra-intense lasers, possibly increasing the current record from 10 Petawatts to 500 Petawatts.
Ultra-intense lasers with ultra-short pulses and ultra-high energies are powerful tools for exploring unknowns in physics, cosmology, material science, etc. With the help of the famous technology “Chirped Pulse Amplification (CPA)” (2018 Nobel Prize in Physics), the current record has reached 10 Petawatts (or 1016 Watts). In a study recently published in Scientific Reports, researchers from Osaka University proposed a concept for next-generation ultra-intense lasers with a simulated peak power up to the Exawatt class (1 Exawatt equals 1000 Petawatts).
The laser, which was invented by Dr. T. H. Maiman in 1960, has one important characteristic of high intensity (or high peak power for pulse lasers): historically, laser peak power has experienced two-stage development. Just after the birth of the laser, Q-switching and mode-locking technologies increased laser peak power to Kilowatt (103 Watt) and Gigawatt (109 Watt) levels. After CPA technology was invented by Gérard Mourou and Donna Strickland in 1985, by which material damage and optical nonlinearity were avoided, laser peak power was dramatically increased to Terawatt (1012 Watt) and Petawatt (1015 Watt) levels. Today, two 10-Petawatt CPA lasers have been demonstrated in Europe (ELI-NP laser) and China (SULF laser), respectively.

Researchers have found a simple way to eliminate almost all sequencing errors produced by a widely used portable DNA sequencer, potentially enabling scientists working outside the lab to study and track microorganisms like the SARS-CoV-2 virus more efficiently.
Using special molecular tags, the team was able to reduce the five-to-15 percent error rate of Oxford Nanopore Technologies’ MinION device to less than 0.005 percent — even when sequencing many long stretches of DNA at a time.
“The MinION has revolutionized the field of genomics by freeing DNA sequencing from the confines of large laboratories,” says Ryan Ziels, an assistant professor of civil engineering at the University of British Columbia and the co-lead author of the study, which was published on January 112021, in Nature Methods. “But until now, researchers haven’t been able to rely on the device in many settings because of its fairly high out-of-the-box error rate.”
Reviews.org Survey results state 51% of Americans would switch to SpaceX Starlink Internet.
🚙 🌊 From the street to underwater depths: The diving car by Switzerland’s Frank M. Rinderknecht is legendary! Every year he develops a vehicle prototype that has never been seen before.
The process normally required extremely high operating temperatures and the yield of methanol was limited. Read the study details here.
SpaceX aims to provide Starlink satellite broadband internet service worldwide. “With performance that far surpasses that of traditional satellite internet, and a global network unbounded by ground infrastructure limitations, Starlink will deliver high speed broadband internet to locations where access has been unreliable, expensive, or completely unavailable,” the company’s website states, “Starlink is now delivering initial beta service both domestically and internationally, and will continue expansion to near global coverage of the populated world in 2021.” SpaceX is currently providing Starlink beta service to select customers living in northern United States, Canada, and United Kingdom. To receive updates about when service will be available in your area sign-up via Starlink.com.
Starlink customers receive broadband internet connection from the satellites in space via a Starlink Kit which includes a phased-array antenna dish, Wi-Fi router, along with power and mounting equipment. The kit is priced at $499 USD, with a monthly service fee of $99 USD. SpaceX has approval from the Federal Communications Commission (FCC) to operate 1 Million dish antennas for customers in the United States. In July, the company submitted a new FCC request to operate 5 Million additional dish terminals in the U.S. – “SpaceX Services requests this increase in authorized units due to the extraordinary demand for access to the Starlink non-geostationary orbit satellite system,” the company wrote in the FCC filing last year. The FCC has not approved the request yet.
Reviews.org, a team that reviews technology products online, conducted a asking 500 Americans if they would switch internet provider once SpaceX’s Starlink broadband service enters the public telecommunications market. “Starlink internet is perfect for those who feel stuck with slow speeds from their internet provider –especially in rural areas where building out cable and fiber networks either takes a long time or is less likely to provide adequate coverage,” Reviews.org wrote in its website. According to the Review.org results, 51% of Americans would switch to SpaceX Starlink Internet service. “51% of internet users say they plan to sign up for the Starlink beta once it becomes available to them. While only 5% of Americans currently use a satellite internet connection, 64% of respondents say Starlink’s rollout would make them reconsider their satellite internet stance,” Review.org representatives wrote in the publication, “55% of non-satellite internet users say they’d switch to Starlink’s satellite internet service at a higher cost if it resulted in faster internet speeds for their household,” they stated. The organization compiled a graphic with more details about the their, pictured below.
