A Second Black Hole Hiding In The Center Of The Milky Way?

Scientists believe that they have found a second black hole near the center of our galaxy, and one which could help explain more about how these mysterious phenomena develop.

The discovery began last year, when Tomoharu Oka and other scientists from Keio University in Japan observed CO–0.40–0.22, a gas cloud 200 light years from the center of the Milky Way Galaxy. The random and quick gas flows from the cloud led to the theory that it contains an intermediate-mass black hole (IMBH).

“Based on the careful analysis of gas kinematics, we concluded that a compact object with a mass of about [100,000] solar masses is lurking in this cloud,” the scientists explained.

The Milky Way Already Harbors a Supermassive Black Hole

A supermassive black hole, Sagittarius A*, lies in the center of our galaxy; it is estimated to be millions or even billion times more massive than the sun.

This is part of what makes the discovery of a second black hole so interesting. Up until now, astronomers have managed to discover some supermassive black holes, and the much smaller stellar-massive black holes (between three and ten times the size of the sun), but not intermediate-massive black holes.

Scientists are hoping that further study of these medium giants could help determine how the supermassive variety develop over time; so far it is unclear how they reach such improbable sizes.

Since they seem to lie in the center of galaxies, it is theorized to be a combination of feeding on galactic junk (including planets and stars) and colliding with other galaxies and their own black holes.

It is also unclear how IMBHs form themselves; they are too large to come from single stars going supernova, like their stellar-massive cousins. Oko’s team theorizes that this new discovery used to be the center of its own dwarf galaxy before colliding with ours.

Here Are the 5 Movies that Dominated the US Box Office This Weekend

This weekend’s box office offer covers all tastes and ages.


August is a bit late for summer blockbusters and early for fall releases, so this weekend (August 18-20) was fairly tame as far as the box office went. But if you are looking for something to see, here are the top five movies for your consideration.

Taking the top spot this weekend is The Hitman’s Bodyguard, a new release starring Samuel L. Jackson as a former assassin about to testify against a dictator and Ryan Reynold as the disgraced bodyguard trying to protect him. It exceeded financial expectations with $21.6 million, though reviews describe it as a fairly average action movie.

Annabelle: Creation came in second with $15.5 million on its second weekend. This horror film about a demonic doll is the fourth installment in The Conjuring series and serves as a prequel to 2014’s Annabelle. Creation managed to wash away the shame of the 2014 prequel which brought shame to the genius of The Conjuring.

Another new release is Logan Lucky, which came in at third with $8.1 million—a pity, since director Steven Soderbergh said that it would need $15 million to be a success. It stars Channing Tatum, Adam Driver and Riley Keough as siblings who plan a heist on the Charlotte Motor Speedway during the Coca-Cola 600.

The extremely popular Dunkirk returns for its fifth weekend, raking in another $6.7 million. It focuses on the Dunkirk Evacuation during World War II, where the British pulled together all of their civilian vessels to help save more than 300,000 soldiers who were pinned down in northern France by the Nazi invasion.

Rounding out the top 5 is The Nut Job 2: Nutty by Nature, which returns for its second week with $5.1 million. This children’s film, about talking animals living in a park, has not done well with audience or critics, performing far below expectations.

The San Antonio Spurs test the waters with their newest team-player, Derrick White

The San Antonio Spurs addressed the backcourt of Thursday’s NBA draft by choosing Derrick White from Colorado with the No. 29 pick. This and other selections came after a week during which the Spurs spoke with at least 3 teams, sources say, regarding a possible trade to get them up to the top half of the first round. This would be in exchange for LaMarcus Aldridge.

The San Antonio Spurs Test the Waters in Search of Co-Player

In regard to the San Antonio Spurs’ draft, their general manager, R.C. Buford said that it is what it is.

“So there’s always all kinds of discussions going around. You never know what’s real, and you never know where you’re gonna get.”, he added.

He later stressed the importance of the group, as it is well-shaped as it is. But, in his opinion, if they can make the group better, no occasion will be spared. And regarding LaMarcurs he said that he thinks that Aldridge will help their team win more tournaments and competition.

The San Antonio Spurs test the waters with LaMarcurs especially in the light of the uncertainty given Parker’s recovery from a torn quadriceps tendon, Patty Mills’ potential departure through free agency in July, and Dejounte Murray’s inexperience as a rookie.

Derrick White is eager to start playing with the Spurs. He has until now only played one season at Colorado, where he’s averaged 18.1 points, 4.4 assists, and 1.2 steal in the ’16-’17 season, which came after his three years at Division II University of Colorado—Colorado Springs.

So the San Antonio Spurs test the waters with their newest acquisition, Derick White, an experienced player, who, the Spurs hope, will help them win more tournaments.

White said in a statement that:

“Each time you have the doubters, you just put a little chip on your shoulder. It was humbling at the time. It just made me work to just continue to never be satisfied”.

Using Tempting Names Could Get People To Eat More Vegetables

June 13, 2017 By Janice Bower Leave a Comment

Researchers wondered if, by using tempting names, they could get people to eat more vegetables.

Researchers at Stanford University set to out to determine if vegetables could become more appealing if their name, just their title changed. To find out the answer, the scientists staged an experiment in the university’s cafeteria, which revealed that people do, in fact, chose dishes with tempting names more than straightforward titled ones.

The study was conducted over a six weeks period and was staged in a dining hall at the Stanford University. Each day, the hall served up one of their vegetable-based dishes during lunch. Nothing was added or taken from either their preparation method or display. Instead, the labels describing the serving got a mix-up. For each meal, the research team randomly selected one of four descriptions.

The first is the basic presentation, and a second one is the “healthy restrictive” variant. This is alternated with a “healthy positive” description or an indulgent one. For example, for a butternut squash, they would either name it as such or go for “butternut squash with no added sugar” or “antioxidant-rich butternut squash” for the healthy variants. The indulgent title was “twisted garlic-ginger butternut squash wedges.”

Tempting Names Elicit More Attention and A Higher Consumption

During each lunch period, the research team secretly recorded how many people chose which variant of the dish. At the same time, they also weighed how much of it was left after the lunch had ended, as compared to when this began.

Study results showed that the tempting names, ‘reigned supreme’. Out of the almost 28,000 diners, over 8,000 chose a vegetable dish across the experiment’s duration. On average, more people chose a veggie serving when this was given an indulgent title when compared to the other three variants.

In contrast, using the healthy restrictive description generated the least interest among diners from all the variants. At the same time, people that chose dishes with tempting names also ate more vegetables when compared to the other options.

According to results, an enticing name can “significantly increased the number of people choosing vegetables and the total mass of vegetables consumed compared with basic or healthy descriptions, despite no changes in vegetable preparation,” state the researchers.

The researchers noted that they were unable to actually determine how much of the food taken in a serving was actually eaten. Research results are available in a paper in the JAMA Internal Medicine.

Pediatricians Impose New Limitations On Fruit Juice Consumption

May 22, 2017 By Janice Bower Leave a Comment

The APP issued a new fruit juice consumption recommendation for kids under the age of 1.

The American Academy of Pediatrics or AAP issued a new recommendation targeting fruit juice consumption. Pediatricians state that children younger than one should drink no such beverages.

Such recommended restrictions already existed but they targeted toddlers six months or less. They also offered limitations in consumption levels for older infants and kids in general.

Now, according to the new release, children under the age of one year old should drink no fruit juice at all. The specialists offer their lack of nutritious gains as the reason behind this guideline change.

Fruit Juice Consumption Brings No Help, But Possible Problems?

The APP released this updated recommendation in a paper in the journal Pediatrics. In it, the specialists claimed that drinking fruit juice brings no nutritional benefits for young kids. They state that small quantities of such beverages are still alright for older aged children.

However, APP offers fresh fruit as the best alternative to juice consumption. They point out the actual fruit’s increased health advantages as this comes with more fiber and less sugar than a glass of juice.

Also, Dr. Steven Abrams stated that drinking too much such juice may actually come with health problems. More precisely, he underlined the possibility of tooth decay or even weight gain.

“Parents may perceive fruit juice as healthy, but it is not a good substitute for fresh fruit and just packs in more sugar and calories,” stated Dr. Melvin B. Heyman.

He is a co-author of the newly released recommendation. Dr. Heyman is also the director of the Pediatric Inflammatory Bowel Diseases Program carried out at the University of California, San Francisco. He explains that small, moderate amounts of fruit juice are quite alright for older kids. But that they are “absolutely unnecessary” for children younger than 1.

The APP recommends parents to encourage their kids, no matter their ages, to eat fresh fruit. These come with more benefits and can and should be consumed at all ages.

Google Chrome on Android should now find it even easier to download and read offline content.

Earlier this week, on May 8th, Google announced that its Chrome for Android application would be updated and upgraded. Through these latest changes, users should find it even easier to view and read offline content.

In the blog post announcing this development, Google pointed out that this reading web pages offline is not necessarily new. The internet giant company first introduced this feature in December 2016. Since then, users could start saving whole pages for reading when completely offline when on the Chrome for Android app.

According to Google, over 45 million web page are saved each week for this very same purpose. Now, this process should be even easier. Users can just long press on a link and then click the “Download link” option. This new feature will also work with article suggestions that appear when opening a new tab page.

Following this latest update, Chrome’s offline dinosaur logo will also come with a friend. If the graphic Dino does appear, it will bring along a “Download Page Later” button. As such, users can rest assured that they lost neither their work or article of interest.

Google stated that “If you tap it [the Download Page Later button], Chrome will automatically download the page for you when you get back online.”

Offline Content Will Now Be Just a Badge and a Click Away

The Chrome developer also simplified the user’s access to saved offline content. From now on, this will appear as you open a new tab. All the downloaded pages will be on display and will be marked by a ‘new offline badge’.

The access to offline content is not the only one to get simplified. Users should now find it easier to reach their recent downloads as these will be displayed as a list on new tab pages.

Google presented this latest set of features as an easy “ready-to-go list of pages or articles” that can be accessed even as the device is out of data or enters a dead network zone. Still, it does point out that users will first have to update to this latest Chrome version before being able to start using this easy download.

Inflatable Greenhouse Could Be A Food Source In The Outer Space

April 29, 2017 By Janice Bower Leave a Comment

A prototype of an inflatable greenhouse may offer the solution to the space food supply problem.

 

As NASA and other scientific groups begin to examine the prospect of sending humans to Mars or other space bodies, one of the primary concerns is their food source. And this is not just during the trip, but while they possibly live for years on another planet. Now, with some new design specs and a few creative ideas, the Prototype Lunar/Mars Greenhouse project may have developed a solution.

Inflatable Greenhouse to Offer Green Food on the Red Planet?

NASA has been working for years with multiple universities to develop the new inflatable greenhouse prototype. Earlier this week, it released new details on the matter. Water and air can be recycled fairly easily with modern technology.

However, the problems regarding a sustainable food source for a colony on Mars are a bit more complicated. Growing potatoes in one’s own ordure may work for Matt Damon, but most mission crews would prefer more dependability and variety in their diets.

That is where this new design comes in. Dr. Ray Wheeler is the lead scientist of this project, working in the Kennedy Advanced Life Support Research.

“We’re working with a team of scientists, engineers and small businesses at the University of Arizona to develop a closed-loop system,” he said. “The approach uses plants to scrub carbon dioxide while providing food and oxygen.”
Waste water would also be purified in this greenhouse, as well as it being an oxygen and food source. Ultimately, the entire planet Earth is a closed-loop system. This new greenhouse system would be an attempt at reproducing that on a much smaller scale.This inflatable greenhouse design uses concepts from similar, Earth-bound structures. They may well be used on a potential joint NASA mission. Currently, this is being called Mars 2030. Many factors are being taken into account in the design, but recycling every resource possible is the primary goal. This is something absolutely essential in all forms of spaceflight and exploration.

Titan’s Magic Islands Received An Official Explanation

April 21, 2017 By Janice Bower Leave a Comment

A team now believes static electricity may well be the culprit behind Titan’s Magic Islands.

 

Titan, Saturn’s biggest moon, is larger than Mercury, and scientists believe that its surface is mostly sand formed by organic molecules. For years, observations have been made of massive dunes flowing across the surface. At times, these dunes form large mountains of sand cheekily called “magic islands” because they seemed to defy gravity and the wind by holding their structure. Through experiments conducted on Earth and observations made by NASA’s Cassini spacecraft, a team now believes static electricity may well be the culprit.

Titan’s Magic Islands Are Not Quite Magic

Just like wet sand holds together to form castles during trips to the beach, static electricity can hold sand together in formations as well. Conditions on Titan seem to be extraordinarily suited for this situation. The atmospheric pressure on Titan is higher than that on Earth, while also being very cold and dry.

This increases the overall effect of the static since the sand mainly serves as an insulator against the massive amount of electricity generated by atmospheric friction. It is also the same friction that creates lightning storms on our planet. However, on Titan, they have far more power.

When the storms get especially active, this charge can then be stored up on the surface of individual particles of sand. This causes them to act as tiny magnets, clinging to one another in defiance of gravity and wind.

Scientists created similar conditions in the lab, and they now believe that a sand castle built on Titan might stand for quite some weeks. It also may explain why so many dunes on the moon’s surface appear to form in defiance of the prevailing winds. Only heavy gusts and storms seem to have the power to move them. So after many years of speculation, it looks like the magic in Titan’s fabled Magic Islands was really simple static electricity all along.
The study team released its research results in a paper published in the Nature Astronomy journal.

Science Discovered And Named A New Dinosaur Species

April 3, 2017 By Janice Bower Leave a Comment

A team of paleontologists discovered a new dinosaur species and named it Daspletosaurus horneri.

A team of paleontologists discovered a new dinosaur species. This is a tyrannosaurine and a cousin of the famous Tyrannosaurus rex, which lived in the Late Cretaceous epoch. The researchers named it Daspletosaurus horneri and it is also known as Horner’s frightful lizard.

The newly discovered dinosaur species probably lived in what is now Montana some 75.2 million to 74.4 million years ago. They were part of a giant predatory dinosaurs group and related to tyrannosaurs. This species lived during the Late Cretaceous in both North America and Asia.

The Newly Discovered Dinosaur Species Had The Following Properties

A Daspletosaurus horneri must have had a body length of about 29.5 feet at a height of around 7.2 feet. It probably had a wide snout and small orbital horns. It may have also had slit-like pneumatic openings placed inside of its lacrimal bone.

It probably had a large horn behind its eye, which would have also been elevated beyond the respective side of its head. Research indicates that this featured a keratin covering.

The Daspletosaurus horneri probably preyed on ceratopsians or horned dinosaurs as well as hadrosaurs or crested duckbill dinosaurs. Also, it may have hunted pachycephalosaurs or dome-headed dinosaurs or theropods, or a smaller species of carnivorous dinosaurs.

A research team took a closer look at the new dinosaur species. They worked with well-preserved fossils, including the skeleton and skull of an adult specimen. Study results were released in a paper in the Scientific Reports journal.

“Daspletosaurus horneri was the youngest, and last, of its lineage that lived after its closest relative, Daspletosaurus torosus, which is found in Alberta, Canada.”

This is according to the study’s lead researcher, Dr. Thomas Carr from the Carthage College. By adding a new species to the tyrannosaur family tree, the researchers also gained new knowledge on their appearance and evolution.

Researchers compared the mortality rate for white Americans in 1999 with the rate now.

A new study focused on the rising of the mortality rate for white Americans. The rate has increased a lot in the last 20 years. Many of these deaths are named deaths of despair. The researchers that conducted this study mentioned that these are caused by suicide, alcohol, and drugs.

This research started in 2015 and was conducted by Angus Deaton and Anne Case from Princeton University. In order to conduct this study, researchers compared the mortality rate for white American in 1999 to the rate now.

They observed that white men are twice more likely to die from alcohol, suicide, or drugs now than they were in 1999. When it comes to women, the rate is even bigger. Women are four times more likely to die from “despair” now than they were 18 years ago.

The mortality rates of Hispanics, Europeans, and black people are smaller when compared to white Americans. The mortality rates are even bigger for people that live in rural areas and have only high school education. These people are the most affected by deaths of despair.

Middle-aged, working-class people with high school education are the ones that suffer from deaths of despair. The researchers mentioned that their research shows the current decline of the working class people that thrived in the 70s.

Scientists mentioned that showing numbers and demonstrated the increase in the mortality rate is simple. The problem came when they looked for remedies. They mentioned that many people need to take action in order to save people from deaths of despair. The government, civic organizations, and businesses should all look for remedies.

The people that are affected by deaths of despair were also the ones that voted for President Donald Trump. This is because he promised to bring back jobs that can be done by people who only have a high school diploma. Manufacturing and coal mine jobs are desired by the middle age working class white American. The researchers mentioned that something should be done for these people before more of them die from alcohol, drug abuse or suicide. They need more than promises.

What is your opinion about this report? Did you know about these “deaths of despair”?
