The US Navy has tested a new laser weapon system, with the video below showing the docked USS Portland testing its new laser weapon system that is capable of blowing an aircraft up out of the sky mid-flight.
In the video above, the US Navy has its USS Portland testing "the first system-level implementation of a high-energy class solid state laser". The laser disables a drone mid-flight, where you can see in the second half of the clip the drone burning from being hit by the laser.
We don't know how strong the laser itself is, but according to a report published in 2018 from the International Institute for Strategic Studies, it's expected to be at least a 150-kilowatt laser. That's some serious laser weaponary right there, but the US Navy hasn't provided any specifics.
I didn't think I'd be typing this news up -- but sometimes stories just write themselves. A team of scientists in Canadian have discovered at least 13 strains of cannabis sativa that could prevent, and even treat COVID-19.
The researchers wrote in their paper: "We have developed over 800 new Cannabis sativa lines and extracts and hypothesized that high-CBD C. sativa extracts may be used to modulate ACE2 expression in COVID-19 target tissues".
They continued: "Screening C. sativa extracts using artificial human 3D models of oral, airway, and intestinal tissues, we identified 13 high CBD C. sativa extracts that modulate ACE2 gene expression and ACE2 protein levels. Our initial data suggest that some C. sativa extract down-regulate serine protease TMPRSS2, another critical protein required for SARS-CoV2 entry into host cells".
I think we've about heard it all when it comes to coronavirus, but each day brings a new surprise -- and some days, and some places it seems more than others. Now God is sending us messages in the form of coronavirus-shaped hailstones.
Residents in the city of Montemorelos in Mexico have taken to social media to post photos of recent weather events, where the formation of hailstones (at least to them) looked like the shape of coronavirus. The posts on social media have Mexicans claiming that the bad weather was an "omen" to the city of Montemorelos.
One particular post on social media said: "Yesterday coronavirus hailstone, God sent it to our home to remind us to stay put". Another post reads: "Is this a subliminal message from our creator?"
We all know the story of the Titanic, with James Cameron's mega-hit movie making billions at the box office -- but the history is well known on the Titanic, and now it's about to get even more interesting. Maybe they just need to turn back time.
An underwater salvage company has been approved to slice into the Titanic wreckage, where they want to salvage the Marconi telegraph from the ship at the bottom of the ocean. Why do we need the telegraph machine from the Titanic? It could have locked away in the depths of the dark ocean some missed warning messages and even distress calls sent from the ship before it sunk.
Judge Rebecca Smith of the U.S. District Court in Norfolk, Va., made some changes to a court order from 2000 that stopped any company from cutting into the hull of the Titanic looking for diamonds. Judge Smith explains: "The Marconi device has significant historical, educational, scientific and cultural value as the device used to make distress calls while the Titanic was sinking".
I thought I was reading the story line to a TV show like Fringe, Lost, or one of my new favorites: Dark -- but nope, this is real. NASA scientists working down in Antarctica have discovered evidence of a parallel universe... where the rules of physics are the opposite of our world.
The idea of a parallel universe is not new at all, and has been the basis of plenty of movies and TV shows over the decades. But now NASA scientists have discovered some interesting things in their experiments in Antarctica, where an cosmic ray detection experiment has discovered new particles that -- get this -- could be from a parallel universe that started at the Big Bang.
NASA scientists have been running experiments using a gigantic balloon that takes ANITA (Antarctic Impulsive Transient Antenna) into the skies high above Antarctica where the very cold, very dry air provides the optimal environment for NASA's testing. They want to evade all radio noise in order to run their experiment.
President Trump is bringing the pain to the World Health Organization (WHO) where he has threatened to cut funding from the WHO over its handling of the COVID-19 pandemic. In recent WHO-related news, the ex-director of the WHO has said that coronavirus could "burn out naturally", more on that here.
President Trump tweeted out his four-page letter to Dr. Tedros, the Director-General of the WHO, saying that the agency must show "independence from China". Trump writes: "If the World Health Organisation does not commit to major substantive improvements within the next 30 days, I will make my temporary freeze of United States funding to the World Health Organisation permanent and reconsider our membership in the organisation".
The letter from President Trump continues: "It is clear the repeated missteps by you and your organization in responding to the pandemic have been extremely costly for the world. The only way forward for the World Health Organization is if it can actually demonstrate independence from China".
Well folks, it looks like we might not need a coronavirus vaccine after all -- as the former World Health Organization (WHO) director said that COVID-19 could "burn out naturally", thus, not needing a vaccine.
The former WHO director tweeted: "There is a real chance that the virus will burn out naturally before any vaccine is developed. We are seeing a roughly similar pattern everywhere - I suspect we have more immunity than estimated. We need to keep slowing the virus, but it could be petering out by itself".
Professor Sikora replied to his own tweet, adding: "It is my opinion that this is a feasible scenario. Nobody is claiming to know what will happen for sure - I believe in an unknown situation this is a possibility. We need to continue to keep our distance and hope the numbers continue to improve".
Italy has been one of the countries hit hardest by the coronavirus, and yet the country's government has just announced that it will reopen in early June.
According to Prime Minister Giuseppe Conte, who spoke publically through a television address to the country, Italy will reopen early June to European tourists. This is an effort by the government to restart the economy, while at same time being extra cautious of a potential second wave of COVID-19. Cote said that gyms and cinemas will also be reopening, and that "We're facing a calculated risk in the knowledge that the contagion curve may rise again. We have to accept it otherwise we will never be able to start up again."
Italy is heavily dependant on its tourism, and early in early March, Cote announced a full shutdown of the country due to coronavirus. Now, the virus has taken nearly 32,000 lives. Italy will also be abandoning the two-week mandatory quarantine when tourists decide to enter the country; this new ruling will begin on June 3. Local authorities will be monitoring the situation, and if they notice a spike in COVID-19 infection cases, they will be limiting travel throughout the region.
Scientists have hit a new milestone in mixing human cells into animal embryos, as researchers have managed to create a human-mouse hybrid.
As reported by ScienceNews, and is something out of a science-fiction horror movie, researchers have reached a new milestone in the stem cell field by modifying human cell proteins and successfully adding them to mice embryos. This is the first time researchers were able to add a large amount of human cells to an animal. The scientists let the embryos develop for 17 days, and after that period of time, they observed that human cells spread throughout much of the mice embryo.
The human cells were found in the tissue that would form the heart, brain, and blood. Scientists noted that all mice that were given this treatment didn't have the same percentage of human cells found in tissues throughout the embryo, but on average, a mouse embryo contained up to 4% human cells. So why do this? Scientists believe that if they can get a firm understanding of stem cell research that one day they will be able to use pigs, for example, to grow human organs that could be used to save lives of people who need them.

Razer has kicked off an interesting new pilot program in Singapore, where the gaming peripheral giant is offering a free COVID-19 fask mask... but it has some (green) strings attached to it. First, check out the #RazerForLife video:
Back when the COVID-19 pandemic first started spreading throughout the globe, many companies were quick off their feet in reacting to it and transitioning supply chains to making face masks and ventilators. Razer was one of those companies, and is now running a new pilot program that is will make one free surgical mask for every resident that is 16 years or older in Singapore.
It is a pilot program just for now, running between May 12 to June 2 with 20 vending machines spread throughout Singapore. Razer will have a full rollout throughout Singapore right as the local shelter-in-place orders are lifted.
