Here's places that have the greatest risk for contracting coronvirus

Jak Connor | Mon, Jun 15 2020 8:33 AM CDT

As the United States begins to slowly reopen in select locations, many people are wondering what places pose the greatest risk for contracting the coronavirus.

Here's places that have the greatest risk for contracting coronvirus 26 | TweakTown.com

Public health experts have taken a survey and ranked common places such as bars and public pools on a scale of 1-10, ten being the greatest risk. According to these four health experts, there are five factors when considering how dangerous a location is; if it's outdoors or indoors, proximity to others, exposure time, likelihood of compliance, and personal risk level.

The public health experts generally agreed that outdoor activities are much safer than indoor activities, and that is mostly due to the virus being less concentrated outside than inside. While outdoors is generally safer, activities such as basketball, or a music concert are still considered risky as the activity is likely to break social distancing guidelines.

A former NASA scientist has released an informative animated video that shows how fast Earth is rotating relative to the Sun, the Milky Way galaxy, and the Cosmic Microwave Background.

The simple animation video found above was created by planetary scientists, and former NASA scientist James O'Donoghue, who wanted to put all of this information into context with a simple and informative video. According to O'Donoghue, "People often talk about how we are standing on a ball (Earth) which rotates at great speed, and that this ball orbits another at an even greater speed. Sometimes this is extended to how fast we orbit the centre of our Milky Way."

O'Donoghue also said, "In all the confusion of big numbers and directions, I simply wanted to put all this information into context in a single frame so people could understand where they're headed - and how fast." Looking at the video, we can on the left-hand side the numbers that show the speed of Earth's rotation (1030 mph). Below the Earth is the Sun, and how fast the Earth rotates in comparison to the Sun, the same goes for the Milky Way galaxy, and then finally the Cosmic Microwave Background that was produced by the Big Bang.

US Surgeon General says wearing face coverings promotes your freedom

Jak Connor | Mon, Jun 15 2020 3:33 AM CDT

This past Sunday, the US Surgeon General took to his personal Twitter to urge everyone to wear face coverings.

US Surgeon General, Jerome Adams addressed the idea that face coverings, or masks are infringing on everyone's freedom of choice right. Adams said that while many people feel like the masks, or coverings are infringing on their freedoms, that wearing the masks actually promotes your freedom.

Adams' way of thinking is that the more face coverings being worn by Americans, the less asymptomatic viral spread, which means more places reopening, and the rate of which they open being faster. Adam's even went onto say, "Exercise and promote your freedom by choosing to wear a face covering!". The Surgeon General isn't the only medical professional urging people to adopt face masks, the Centers for Disease and Prevention has also pushed for everyone to adopt a face covering if they are venturing outside of their house and to a place that makes social distancing guidelines difficult to follow e.g a grocery store.

A new announcement out of the University of Queensland has revealed that Australia is currently moving toward launching its own domestically-made hybrid rocket. This hybrid rocket is expected to take satellites into low Earth orbit, and will be completely constructed of components made in Australia - meaning that Australia won't have to out-source components from a different country.

University of Queensland's Dr. Ingo Jahn said, "Rather than buying products from overseas, the rockets and components will be manufactured in Australia, and this is an essential step towards developing a space launch vehicle industry in Queensland with many expected flow-down benefits to our manufacturing industries". The teams focus is developing and validating fuel systems, which according to Jahn, is "one of the most complex engineering challenges".

The spiritual healer kissed peoples hands to cure them of coronavirus, has died of coronavirus. Vice.com reports that the "Baba" or "self-styled holy man was apparently a black magic healer from the Ratlam district". He cured people by kissing their hands.

Ratlam's District Magistrate Ruchika Chauhan told VICE on a phone call: "He got himself tested for coronavirus after he began having severe symptoms, and passed away immediately. From the contact tracing we have done so far, seven of his family members and thirteen followers have tested positive. We are investigating the transmission and trying to contain it".

VIPER stands for "Volatiles Investigating Polar Exploration Rover", and the purpose of the mission is to see if the Moon has any traces of water, specifically on the Moon's South Pole. VIPER discovering a source of water on the Moon is an extremely important step for the overall success of NASA's Artemis mission, which will take the next American man, and the first American woman to the lunar surface by 2024.

NASA has selected Pittsburgh-based Astrobotic to build the $199.5 million dollar water-hunting rover. Astrobotic CEO John Thornton commented on the landing the contract, saying, "It is an enormous honor and responsibility to be chosen by NASA to deliver this mission of national importance. Astrobotic's lunar logistics services were created to open a new era on the Moon. Delivering VIPER to look for water, and setting the stage for the first human crew since Apollo, embodies our mission as a company."

Black Hole confirmed to have regular 'heartbeat', here's how and why

Jak Connor | Fri, Jun 12 2020 2:37 AM CDT

A black hole that is located 600 million light-years from Earth has been rediscovered to have a regular "heartbeat".

The new findings were discovered by researchers from the National Astronomical Observatories, Chinese Academy of Sciences, China, as well as researchers from Durham University, UK. The report was published in the journal Monthly Notices of the Royal Astronomical Society, and details a black hole that was first detected to have a "heartbeat" back in 2007. Since then, astronomers haven't been able to pick up a signal from the black hole as our Sun was blocking it out.

Now, researchers used the European Space Agency's XMM-Newton X-ray satellite, and have confirmed that the black hole is still beating like a heart. So why does this black hole beat like a heart? According to Professor Chris Done, in Durham University's Centre for Extragalactic Astronomy, who collaborated on the research, "The main idea for how this heartbeat is formed is that the inner parts of the accretion disc are expanding and contracting." Done also said, "The only other system we know which seems to do the same thing is a 100,000 times smaller stellar-mass black hole in our Milky Way, fed by a binary companion star, with correspondingly smaller luminosities and timescales."

Mayan doomsday calendar was wrong, world now ends on June 21, 2020

Anthony Garreffa | Wed, Jun 10 2020 10:33 PM CDT

I still remember where I was, and what I was doing on December 21, 2012 -- the day the world was meant to end. It was the last day of my 10 years of managing a computer store in my home state, and shifting into working full-time for TweakTown. But man, I was off by 8 years... the end of the world is on June 21, 2020.

Yeah -- sorry folks, the world is ending on June 21, 2020 -- around 10 days from now.

Mayan doomsday calendar was wrong, world now ends on June 21, 2020 11 | TweakTown.com

Why? How? Well, that's because the Gregorian calendar being introduced in 1582 by Pope Gregory XIII made important changes that was used by the Julian calendar. The biggest thing here is that it removed 11 days from our year, to better reflect the time it takes the pale blue dot we call Earth to orbit around the Sun.

It didn't happen without protest, with the English calendar rights of 1752 seeing British people take to the streets shouting "Give us our 11 days!" This happened because Britain switched over from the Julian calendar to the Gregorian calendar, which aligned them with Europe -- and people weren't happy about that, losing 11 days and all.

Repetitive negative thinking patterns linked to increase dementia risk

Jak Connor | Tue, Jun 9 2020 9:02 AM CDT

A new study has indicated that constantly thinking about negative thoughts could increase the risk of a person developing dementia.

Repetitive negative thinking patterns linked to increase dementia risk 01 | TweakTown.com

According to the UCL-led study published in Alzheimer's & Dementia, researchers looked at over 292 people over the age of 55 and found that 'repetitive negative thinking' (RNT) is linked to subsequent cognitive decline, as well as the deposition of harmful brain proteins that are linked to Alzheimer's. Lead author Dr. Natalie Marchant, a UCL Psychiatrist said, "Depression and anxiety in mid-life and old age are already known to be risk factors for dementia. Here, we found that certain thinking patterns implicated in depression and anxiety could be an underlying reason why people with those disorders are more likely to develop dementia.".

Marchant also says that from the research, scientists believe that chronic negative thinking patterns that occur over longer periods of time could increase the risk of dementia. Marchant also explains that the evidence gathered doesn't suggest that short term negative thinking would increase the chances of one developing dementia. The researchers behind the study now hope that RNT is further investigated as a potential risk factor for dementia and that other tools that can break someone's negative thinking pattern/s are also explored as treatments.

Astronomers spot Earth-like planet that has a yearly cycle of 378 days

Jak Connor | Tue, Jun 9 2020 4:04 AM CDT

It's always a blast when astronomers spot another planet that is really similar to Earth, as most planets out there are baron wastelands that are either too hot or too cold.

Luckily, astronomers are really good at finding planets, and sometimes with a little bit of luck, they find one that is really similar to Earth. According to a new report in MIT Technology Review, astronomers have located a new planet that is likely an exoplanet, and it's called KOI-456.04. This planet is just under two times the size of Earth, and shares about 93% of the same light our planet receives.

The team managed to locate this planet with the old Kepler Space Telescope, and pulled the diamond in the rough out using algorithms that study a star's brightness. The algorithms target a star and constantly observe it waiting for it to dim, and once it does dim, it indicates an object, and sometimes a planet has passed in front of it. While I previously do say that KOI-456.04 is a planet, I must be accurate; scientists are 85% sure that KOI-456.04 is a planet, but for that to be confirmed, studies have to hit the 99% mark. Once that mark is hit, KOI-456.04 is officially an exoplanet.
