Scientists said rats are good drivers when they are mentally stimulated. They taught rats to drive a mini rat-sized car. And Rats actually learned how to drive their own tiny cars.

According to scientists’ beliefs, this could advance human mental health too. As both, the brains of humans and rats share the same neurochemicals and area. However, humans still have a more complex brain structure than rats. There are some “universal truths” on how both species’ brains can interact within their environment.

Scientists found the real discovery in the fecal matter of the rats

According to the new findings published in Behavioural Brain Research, scientists found real discovery in the fecal matter of rats. For the procedure, a group of scientists trained two groups of young rats. They left one group in an enriched environment with toys, ladders, balls, and pieces of wood. It is all designed to spark mental stimulation. They left another group in a standard, unexciting lab cage.

Scientists found that rats learned to enter a custom “rat-operated vehicle,” or ROV. This vehicle is adorably constructed from a one-gallon plastic container turned on its side.

At the end of the experiment, scientists found that both groups of rats trained to drive secreted higher levels of hormones. These hormones include corticosterone and DHEA, hormones that control stress responses.

Corticosterone hormone is generally secreted by animals in high-stakes scenarios. These scenarios include running from a wild animal or defending themselves from predators. It also includes sometimes lower risk tasks. However, DHEA acts as a sort of buffer when corticosterone becomes toxic.

So, this corticosterone hormone has implications on human health too. Scientists refer to the release of hormones on “behaviorceuticals activities”. It reduces stress can build resilience against the onset of mental illness.

Vitamin D high doses cannot be used for treatment of Coronavirus, Study Warns

Vitamin D high doses cannot be used for treatment of Coronavirus, Study Warns

GUILDFORD, England — There have been several reports claiming that lots of vitamin D (higher than 4000IU/d) can help fight off COVID-19 and stop the virus from manifesting severe symptoms. A new study from the University of Surrey, however, disputes this theory.

A team of international researchers from the U.S., United Kingdom, and Europe all agree that there just isn’t enough valid evidence that vitamin D is effective at preventing or treating COVID-19 and its deadly symptoms. The study’s authors specifically warn against ingesting high doses of vitamin D as a means of protecting oneself from the coronavirus.

“An adequate level of vitamin D in the body is crucial to our overall health, too little can lead to rickets or the development of osteoporosis but too much can lead to an increase in calcium levels in the blood which could be particularly harmful,” says lead study author Professor Sue Lanham-New, Head of the Department of Nutritional Sciences at the University of Surrey, in a release

.

The research team went through all available data on the influence of vitamin D on viral infections and found no evidence that high doses of vitamin D can help fight COVID-19. If anything, taking too much vitamin D will lead to health complications in many instances. They believe these earlier studies touting the benefits of vitamin D against the coronavirus were based on inadequate research.

There have also been recent claims of there being a link between low vitamin D levels and increased risk of respiratory tract infections, but again, the study’s authors found some big holes in that idea. Prior studies that had come to that conclusion used data from underdeveloped nations, so those findings really aren’t applicable to more developed countries.

“Most of our vitamin D comes from exposure to sunlight, however for many people, particularly those who are self-isolating with limited access to sunlight during the current pandemic, getting enough vitamin D may be a real challenge. Supplementing with vitamin D is recommended but should be done under the current UK guidance,” comments co-author Professor Carolyn Greig of Birmingham University. “Although there is some evidence that low vitamin D is associated with acute respiratory tract infections, there is currently insufficient evidence for vitamin D as a treatment for COVID-19 and over-supplementing must be avoided as it could be harmful.”

“In line with the latest Public Health England guidance on vitamin D, we recommend that people consider taking a vitamin D supplement of 10 micrograms a day during the winter months (from October to March), and all year round if their time outside is limited,” concludes co-author Professor Judy Buttriss, Director General of the British Nutrition Foundation. “Levels of the vitamin in the body can also be supplemented through a nutritionally balanced diet including foods that provide the vitamin, such as oily fish, red meat, egg yolk and fortified foods such as breakfast cereals, and safe sunlight exposure to boost vitamin D status.”

The study is published in BMJ Nutrition, Prevention & Health.

World’s Largest shield Volcano Pūhāhonu aka Gardner Pinnacles found in Hawaii

World's Largest shield Volcano Pūhāhonu aka Gardner Pinnacles found in Hawaii

With two barren peaks that rise only about 170 feet above sea level, the now extinct Pūhāhonu volcano in the Northwestern Hawaii Islands doesn’t look like much. This is especially true since in the same archipelago, Mauna Loa towers over every other volcano at 30,000 feet.

Scientists at the University of Hawai’i at Mānoa have proved that looks can be deceiving.

new study published in the Earth and Planetary Science Letters journal establishes that Pūhāhonu is the largest shield volcano in the world, taking Mauna Loa’s title.

Scientists surveyed the ocean floor and used quantitative modeling to determine that the volcano, which is about 171 miles long and 56 miles wide, is twice the size of Mauna Loa.

“Pūhāhonu is massive,” the study reads. So much so that it is causing the Earth’s crust to sink.

“Rapid loading of the crust causes it to subside,” Michael Garcia, lead author of the study, told CNN. “When a giant volcano forms, the hot mantle flows away from the weight allowing the volcano to sink.”

Located about 621 miles north west of Honolulu, Pūhāhonu’s name translates to “turtle surfacing for air” in Hawaiian. The small peaks above sea level have also been known as “Gardner Pinnacles.”

American whaler Maro first sighted Pūhāhonu in 1820, and the crew of a Russian vessel first landed on it in 1828. The volcano is now part of the Papahānaumokuākea Marine National Monument, established in 2006.

The island is home to only one species of plants, the sea purslane, a succulent, but is an ideal habitat for a wide range of fish, corals, and insects.

A 1974 study originally considered Pūhāhonu as the largest volcano in the Hawaiian-Emperor Chain, based on limited survey data. Later studies, which examined both what’s above and beneath the surface of the sea, concluded that Mauna Loa was the largest volcano. The current study updates that conclusion.

Pūhāhonu is not only the largest volcano in the world, it is also the hottest. The two things are interconnected, Garcia said.

“Volume and temperature go hand in hand. Large volume comes from hot magma. It is more likely to erupt if it is hot,” Garcia told CNN.

An analysis of rocks sampled from the volcano was used to determine the magma temperature, and found it to be about 3,092 degrees Farehenheit.

“Finding Earth’s largest shield volcano in the 21st Century is a surprising discovery, but then we know more about the surface of Mars than what is below the ocean on Earth,” Garcia told CNN.

“We are still discovering things about our physical planet that we did not know. There is still much to learn about planet Earth.”

Pentagon declassifies Navy videos that purportedly show UFOs

In recent news, the Pentagon went on to declassify 3 previously leaked video from the U.S. Navy that was considered top secret. These videos showed some unexplained patterns of aerial phenomena believed by some to be UFOs or the Unidentified Flying Objects.

As per a spokesperson by Pentagon, it was revealed that this move would clear up the associated misconceptions lingering among the public on the video being real or fake. Up until now, the phenomenon has been termed as unidentified.

These videos captured what the fighter pilots of the Navy saw over their sensor during the 2004 & 2015 training flights. The information about these videos was initially published by the popular news carrier New York Times in the year 2017.

In the statement provided by the spokesperson of the Defense Department on Monday, it was noted that these three Navy videos had been authorized for release in 2004 November and 2015 January. These videos had been circulating amid the public after their unauthorized releases that happened in the year 2007 & 2017 mentioned Susan Gough, the spokesperson for the Defense Department on Monday.

In the month of March 2018, the 3rd video was finally released.
