Rocky Planet Formation Found in Binary System

rocky planet in orbit

Scientists found a rocky planet orbiting two stars, similar to Tatooine.

Considering the incredible expanse of the Universe it isn’t that hard to believe that it may contain even particular system described in works of science-fiction such as the Star Wars universe’s Tatooine planet which orbits around two stars.

Scientists have recently found evidence of a rocky planet formation formed from shattered asteroids which are currently orbiting a pair of stars. This suggests that among the many possibilities of an infinite Universe, even scenarios described in fiction may very well be possible.

However, the most important aspect of the discovery is that it suggests that rocky planet formations may very well be capable of surviving the death of their own stars, according to the study’s researchers. Despite the fact that our planet only orbits one star, there many other star system home to two or more stars, orbiting each other. In fact, scientists have even discovered system with up to seven stars.

Planets like Star Wars’ Tatooine, which orbit two stars, are known as circumbinary planets. The first discovery of such a planet happened in 2011. The planet has been named Kepler-16b and it is gas giant located around 200 light-years away from Earth.

Until now, all the circumbinary planets that were discovered were found to be gas giants, and astronomers became skeptical that they would ever find a rocky planet which orbits two stars, similar to Tatooine, where Luke Skywalker lived at the start of the series.

According to Jay Farihi, the lead author of the study, and an astrophysicist at the University College London, circumbinary rocky planets seem to be incredibly rare due to the fact that the gravity of two stars would impede the various parts of dust and rock to stick together and form a planet, as they push and pull from different directions.

The scientists discovered the first circumbinary rocky planet in a star system known as SDSS 1557, which is located around 1,000 light-years away from Earth. It was first thought to only include a white dwarf, but a closer analysis revealed the existence of another star, a brown dwarf equal in mass to around 65 Jupiters.

What do you think about the discovery? Are you excited about the discovery of a planet similar to Tatooine?

Neanderthal DNA Still Affects Modern People

Neanderthal DNA still affects the traits of modern humans.

When scientists analyzed our entire genetic history, they found remnants of Neanderthal DNA. Now, a new study reveals that those genes still affects modern people in regards to their appearance and health. While Neanderthals are believed to have died out more than 40,000 years ago, it seems that they still make their presence felt today.

Remnants of Neanderthal DNA can still be found in our genes due to the fact that our ancestors had mated with the less-evolved species, and thus passed their genes further down to the next generations. Now, researchers from the United States have shed some light on how their genes still affect modern people.

According to Joshua Akey, a co-author of the study and a geneticist at the University of Washington stated that the ancient DNA influence several traits of modern humans such as height and the chance of suffering from diseases like schizophrenia and lupus. The impact of the Neanderthal DNA is still considerable despite the fact that the last human-Neanderthal mating like occurred more than 50,000 years ago.

Previous studies have shown that the Neanderthal genetic variants are linked to vulnerabilities to several conditions. However, the mechanisms which caused those effects still eludes scientists. Therefore, the team of researchers started to collect data from the Genotype-Tissues Expression Project, which analyzed people who carry both the modern and the Neanderthal version of a gene.

Using this data, the scientists were able to create a clearer picture and better understand how the Neanderthal genes affect the traits of modern humans, in a quite pervasive and important way. For example, the Neanderthal version of the gene known as ADAMTSL3 is tied to both schizophrenia and height. The study found that, overall, causal mutation and the way in which genes are turned on or off in humans today, have been inherited from Neanderthals.

The study, published in the journal Cell, emphasizes the fact that the interbreeding with the Neanderthals still remains a source of worry for modern humans as it leads to a greater genomic complexity. The researchers also want to examine how other hominid species like the Denisovans contribute to our genetic makeup.

Record Number Of Manatees Might Make Them Lose Endangered Status

manatees endangered status

Manatees might lose their endangered status.

Manatees are listed as endangered and this might change in a few weeks. The US Fish and Wildlife Service is going to decide whether or not the manatees are going to remain listed as endangered. The service is planning on listing the manatees as threatened.

The agency wants to list the animal as threatened due to the fact that it started to recover. The number of manatees in Florida has reached a new record. There are more than 6,000 specimens. Until now, in Florida, there were 3,400 specimens.

This record number of manatees has been seen for the last 3 years. This means that the manatees are recovering and that the endangered status is too much for them. This means that the decision to list them as threatened is better for their recovery.

Despite the fact that this is a sign of recovery, the manatees should be watched and protected at all times. The number of manatees in Florida is affected by the cold waters in the winter and by motorboats that are found along the coastlines. In order to increase the number of manatees, Florida invests $2 million every year.

The Endangered Species List uses the endangered status for species that are facing extinction. The threatened status is used for animals that are likely to become endangered in the future. Many people believe that the manatees should maintain the same status, despite their numbers increasing. They believe that the species is not recovered and that they need more time before their status can be changed.

The US Fish and Wildlife Service mentioned that there are limited resources and that is why they have to focus on the animals that are considered endangered. When there are too many animals with this status, they can’t help them all. They have to list the manatees as threatened because they have recovered enough for the moment.

The agency also mentioned that this does not mean that the manatees will lose their protection. They are still going to be protected under the Marine Mammal Protection Act and the Endangered Species Act. We’ll just have to wait and see what the US Fish and Wildlife Service decides.

Do you think that the manatees should be listed as threatened? Do you think that they are recovered?

Microsoft’s HoloLens Headset May Launch in 2019

Microsoft's HoloLens Headset

The HoloLens headset V3 may launch in 2019.

Ever since Microsoft has unveiled its augmented reality headset, many people were eager to get their hands on it. However, despite the fact that Microsoft decided to release the developer version of the HoloLens headset back in March 2016, the price tag of $3,000, meant that it wasn’t readily available for the vast majority of interested customers.

The latest report involving Microsoft’s AR device involves its plans to skip the second version and go straight into the development of the third, which may be the final consumer version and may be launched in 2019.

The news involving Microsoft’s plan for the HoloLens headset were revealed by a report from Thurrott, citing reliable sources close to the company’s project. This news fits well with other previous reports which claimed that Microsoft has decided to change its initial planned roadmap for the release of the AR headset. This means that the company has canceled the second version of the headset, and instead focusing on the development of the HoloLens headset V3, which may very well be the consumer-ready version.

Skipping the second version of the headset means that Microsoft can accelerate the process behind the V3, as the company comes closer to a generational leap as a way to stay ahead of its competitors. The fact that the HoloLens headset may launch in 2019 at the earliest is sure to disappoint some fans, who were eagerly waiting for the device but either could not afford the developer version or they saw no point in buying it without any adequate content.

However, Microsoft now has enough time to make sure that the HoloLens will meet the expectation of the fans. Furthermore, the V3 headset means that Microsoft has vastly improved the experience provided by the first generation of the device.

When Microsoft decided to sell the developer version of the HoloLens headset back in 2016, they only managed to sell several thousand. However, considering the price and the fact that it wasn’t a device meant for the mass market, Microsoft is not too disappointed about the sales number.

What do you think about the HoloLens headset? Do you prefer full virtual reality over augmented reality?

Atomico Raises $765 Million Fund

Niklas Zennstrom

Atomico concluded its fourth round of raising funds with $765 million.

Atomico has revealed that it has closed its fourth round of raising funds after managing to gather $765 million, which is among the highest venture capital funds in Europe. The company initially started its latest round almost one year ago, revealed through its SEC filings.

The $765 fund is a significant increase over its third fund round which only managed to raise $476 million back in 2013. What is particularly interesting with its very successful fundraising round is that it highlights a key difference between European companies and those in the US, where limited partnership firms are often pressured in committing to top funds.

Atomico’s successful round of funding was due to the stakes the company has in a number of prominent endeavors and other firms, which appealed to a lot of investors it seems. Atomico has shares in Rovio, the Finnish game developer which produced Angry Birds, Klarna, a payments company, as well as GoEuro, a travel site.

The company further benefited from a major transaction back in 2013, when Monsanto acquired Climate Corp. for around $1 billion. The following years was quite successful for Atomico again, when Supercell managed to sell a majority stake to Tencent, China, for $8.6 billion.

Mattias Ljungman, a general partner at Atomico, stated that unlike the U.S. which has a long tradition of investing in various venture capital firms, Europe is only now starting to see the appeal. However, once the benefits of investing in these firms became evident, it led to a large amount of capital being deployed, that even surpassed the US.

Atomico, which was originally founded by the co-founder of Skype, Niklas Zennstrom, has now become of the best-funded firms in Europe. The company has its central office in London but has a lot of people on the ground in major cities across the world such as New York, Beijing, Tokyo, Sao Paulo, and Stockholm.

Atomico offers an extensive list of service to its portfolio companies, such as an in-house value creation team. This team includes around seven partners who mainly advise on marketing, communications, and other domains of interest. Atomico hopes to see that Europe’s venture capital reach the same breakout speed as in the US.

Women Tend to Skip Mammograms After False Positive Results

False positive mammograms leads to greater delays for the next test.

A new study has found that women suspected of having breast cancer tend to delay future mammograms after their first test was a false positive. Furthermore, some women do not even show up for their next screening, which decreases the chance of an early future diagnosis.

The study, published in the journal Cancer Epidemiology, Biomarkers and Prevention, was conducted on more than 261,000 women from the greater Chicago area. The study reveals that false positives have several unintended consequences which can alter the behavior of women regarding mammogram tests.

Researchers found that in the situations where women were recommended to have a test every year, those who received an initial false positive tended to delay their next test by up to 13 months, while women who had a direct negative result scheduled their next test between three to six months.

This delay could lead to reduced chances of survival if the breast cancer is subsequently diagnosed. Scientists revealed that the women who did not receive a false positive test result had a 0.3 percent of being diagnosed with advanced breast cancer tumor. However, for women with false positive tests, the chances increased to 0.4 percent.

Throughout their study, the researchers also found that some of the women never showed for their next mammogram at all. However, it is unclear whether they gave up on being tested for breast cancer or if they just received the test somewhere else.

The lead author of the study, Firas Dabbous working at the Advocate Lutheran General Hospital, Illinois, revealed the delicate balance that is required in breast cancer diagnosis. While early detection offers the best chances of successful treatment, they also don’t want to bother women with increased number of false positive results followed by painful and expensive tests like biopsies.

In this regard, a debate has arisen whether or not the benefit of breast cancer screening outweighs the possible emotional and financial costs of the tests. A mammogram has a one in ten chance of producing a false positive result. Furthermore, an estimated 7 to 17 percent of all false positive women will end up having a biopsy.

Scientists Unveil Blueprint for Modular Quantum Computer

Scientists unveil blueprint for modular quantum computer

Quantum computing has long been considered to be the future of technology, but scientists were not able to reach that goal as of yet. However, an international team of researchers has unveiled their plans on how to build a large-scale quantum computer.

The team of researchers was led by scientists from the University of Sussex, who designed a blueprint for a modular quantum computer, which has the potential to be more powerful than any other system currently available. More specifically, scientists believe that quantum computing is capable of calculating processes millions of times faster than current computer technology.

However, before anyone starts building the modular quantum computer, the blueprint will be analyzed by various specialists in order to determine whether it is viable or not. If so, then we could see the development of the first quantum computer in the coming decade. The scientists published their findings and the actual blueprint in the journal Science Advances.

To compile and design the blueprint, researchers from the UK, Denmark, Japan, Germany and the US have combined their efforts and resources. The result is an actual plan to create a modular quantum computer on a large, something that once was thought of as impossible.

In other quantum computer-related news, researchers have revealed their plans on how to protect future quantum computers from external hacking attacks. Despite their advanced technology, even quantum computers, which hold information in multiple states, not just 0 and 1, can be hacked, according to the researchers. To showcase their claim, the researchers actually built the first high-dimensional cloning machine which was capable of intercepting a quantum message.

In analyzing the results of their experiments, the scientists found important clues which could help protect quantum networks from potential attacks. More specifically, cloning attacks inadvertently introduce specific noises in a channel. Scientists can combat external hacks by ensuring that the more information is contained in photons and monitor those observable noises as a way to strengthen the network’s resistance to external attacks.

However, the development of the large-scale modular quantum computer and securing its quantum networks will not be available anytime soon, if at all, depending on how viable the blueprint is.

Comcast Begins Testing Xfinity TV Beta App

Xfinity TV app fo Roku

Comcast has begun the beta test for its Xfinity TV app.

In recent years, there have been launched several TV streaming apps trying to emulate the success of Netflix. However, it seems that a large number of apps have only made it harder for new and interesting apps to stand out against more established services. Now, Comcast is trying its luck having begun its beta test for the Xfinity TV app on Roku.

Comcast has announced that anyone with a Roku set-top box released in the last two years or those who own a Roku TV, can now install the Xfinity TV app and try out its content and features in a beta test. The official version of the app will make its way to all interested consumers later this year.

The recent news comes after almost a year since Comcast announced that it’s developing the Xfinity TV app for Roku devices and Samsung TVs. This level of integration will allow consumers to watch their favorite live channels without having to pay the cost of cable or even that of a cable box.

The announcement was made by Andrew Ferrone, Roku’s Vice-president of Pay TV, who stated that Roku owners will be able to watch both live and on-demand programming from a variety of sources such as local broadcast or even their cloud DVR recordings. The content will be delivered over Comcast’s privately managed network.

If you’re interested in the Xfinity app, you can install from Roku’s channel store. The participants in the beta test will have access to the full extent of live and on-demand content. However, they won’t be able to either rent or purchase content or even be able to play previously purchased content through the app.

Furthermore, the Roku device will need to be connected to your local Wi-Fi Network in order for the Xfinity TV app to function. The app won’t work if the streaming device is connected to a different network.

Comcast has revealed that the content delivered through the app is not internet-based so you will not rack up your internet bill if you have a limited plan. Instead, the app uses  Title VI cable service provided by Comcast, and therefore it won’t count to the data usage plan.

Pet Rats Caused Seoul Virus Outbreak

Pet rats caused a Seoul virus outbreak in the US.

Humans like to keep as pet various animals, from the conventional dog or cat to more exotic creatures. However, some can more dangerous than others. A new report from the CDC has revealed that the recent Seoul virus outbreak in Wisconsin and Illinois has been caused by pet rats.

The United States is not entirely unfamiliar with the disease as previous outbreaks in the country have been caused by wild rats. However, the recent outbreak occurred due to pet rats. An outbreak with a similar caused has also occurred in Europe.

The first identified patient to come in contact with the virus was in Wisconsin. He visited a hospital with symptoms similar to that of flu. However, the doctors decided to test for hantavirus, as he was breeding rodents in his house, and the virus is often carried by rats, both wild and domesticated.

The results of the test came back in the last days of December and confirmed the fact that patient was infected with the hantavirus. The doctors decided to send the CDC a sample of the patient’s blood together with another sample from one of his family members who also worked with the pet rats.

A few days later, on January 11, the CDC reported that both individuals have been infected with the Seoul virus which is hantavirus commonly found in rats and can cause chills, fever, nausea, and abdominal pain.

The patients infected with this virus tend to develop symptoms as soon as one or two weeks after contact. However, there have been cases where the symptoms started to show even eight weeks after. Fortunately, most patients infected with the Seoul virus can recover, but there have been rare cases where patients have developed a hantavirus pulmonary syndrome. This condition starts with fatigue, fever, and acute pain, and can even become fatal.

Besides the two initial patients, which made a successful recovery, doctors have also identified six other patients working at various other rat breeding facilities in Illinois. Among the six patients, only one has experienced the symptoms of the illness. Health authorities continue to investigate and will very likely find more patients infected with the Seoul virus.

Faraday Future FF 91 Costs an Estimated $300,000

Faraday Future FF 91

Faraday Future investor reveals an estimated price of the company’s car.

Faraday Future decided to unveil their new FF 92 electric car at the Consumer Electronic Show 2017. By all accounts it was a night to remember for all those present, taking into account both the negatives and positives aspect of the presentation, despite being revealed amidst high expectations and serious hype.

The company hopes to compete with Tesla and its high-end electric cars. However, while the specs of the car were unveiled at CES such as having a range of 378 miles thanks to its 130-kWh lithium-ion battery. The Faraday Future FF 91 has revealed to have 1,050 horsepower allowing it to reach 60 mph in 2.4 seconds.

However, the most notable aspect of the presentation was the lack of any pricing details, which could affect a lot of people’s interest in the supposed Tesla competitor. The selling price of the vehicle, as well as its manufacturing costs, are an important detail for the future of a startup company which seeks to sell a high-end vehicle right off the bat.

In a recent interview, one of the company’s main and public backers, Chinese billionaire Jia Yueting, the head of LeEco, an electronics company from China, has stated that he expects the car to cost less than 2 million yuan. When converted to American dollars, this equals around $290,000.

It is unclear if the price only applies in China, considering he mentioned the price in Chinese currency. If this is the case, it’s worth remembering that China does have higher prices due to taxes, increased shipping costs, as well as import duties, if Faraday Future will build the car outside China.

In this regard, LeEco announced last year that one of its Chinese factories will build around 400,000 electric cars per year. However, it is unclear if the factory will be building the FF 91 or vehicles under the LeEco brand itself.

Nonetheless, if price estimated around $300,000 for the Faraday Future FF 91 is the actual international price of the car, this means that it will be vastly more expensive than any of Tesla’s current vehicles, or any of its other competitors. For example, the high-end Model S P100D Tesla starts at $135, 700. Other startup companies like Lucid Motors, estimates that its Air luxury electric sedan will be priced at $100,000 by 2018.
