Einstein’s special relativity has proven more useful than ever, as scientists have now used it to discover an alien planet around another star.
The newfound world, nicknamed “Einstein’s planet” by the astronomers who discovered it, is the latest of more than 800 planets known to exist beyond our solar system, and the first to be found through this method.
The planet, officially known as Kepler-76b, is 25 percent larger than Jupiter and weighs about twice as much, putting it in a class known as “hot Jupiters.” The world orbits a star located about 2,000 light-years from Earth in the constellation Cygnus. [7 Ways to Discover Alien Planets]
The researchers capitalized on subtle effects predicted by Albert Einstein’s special theory of relativity to find the planet. The first is called the “beaming” effect, and occurs when light from the parent star brightens as its planet tugs it a nudge closer to Earth, and dims as the planet pulls it away. Relativistic effects cause light particles, called photons, to pile up and become focused in the direction of the star’s motion.
“This is the first time that this aspect of Einstein’s theory of relativity has been used to discover a planet,” research team member Tsevi Mazeh of Tel Aviv University in Israel said in a statement.
Samsung Electronics said Monday it has made a breakthrough in developing mobile technology for fifth-generation networks, though it expects it will take years until the service is brought online for subscribers.
The South Korean company said it has found a way to transmit large volumes of data using a much higher frequency band than conventional ones in use, which would eventually allow users to send massive data files at a much faster speeds through their mobile devices, “practically without limitation.”
The technology could easily gain fans among phone users routinely sending and receiving large amounts of data. With 5G networks, for example, users would be able to send super-high-definition movie files in a matter of seconds, according to Samsung.
The fastest wireless technology in operation (i.e. the 4G or long-term evolution) has yet to be widely adopted world-wide, and the next immediate phase for the standard is likely to be a shift to “4.5G” networks, analysts say. Many networks still employ 3G.
Samsung has eyes on commercializing 5G technology by 2020, matching a recently set target by the European Union. The EU announced earlier this year a plan to invest 50 million euros in research to deliver 5G mobile technology by 2020.
Many mobile operators are still transitioning to 4G wireless technology and they would have to be as swift in deploying the next-generation wireless data networks for the transition to 5G to materialize as planned, analysts note.
“The competition for technology leadership in next-generation mobile communications development is getting increasingly fierce,” and Samsung “believes it will trigger the creation of international alliances and the timely commercialization of related mobile broadband services,” the company said.
A 105-year-old Texas woman has earned a place in almost all headlines by revealing the most unlikely secret to her long life.
Strangely, her key to longevity is bacon. Yes, you read it right; 105-year-old Pearl Cantrell loves to eat bacon and feasts on it almost every day. Her story, for sure, will be a subject of research for most health scientists.
Pearl Cantrell, who’s mostly referred to as the ’105-year-old bacon woman’, said in an interview with a local NBC station, “I love bacon and I eat it everyday. I don’t feel as old as I am, that’s all I can say.”
Resident of Central Texas, Cantrell, a mother of seven, has outlived three of her kids, as well as her husband. Her recent 105th birthday bash was a three-day affair that included more than 200 guests.
Reports according to KRBC state that Cantrell’s love for bacon grabbed the attention of the American meat and cold cut production company Oscar Mayer. A representative of the company was present at Cantrell’s birthday. The spokesman reached her home in a Wienermobile and gave the ‘bacon woman’ a ride in the hot dog-shaped truck, gifting her tons of bacon, with more to come in the future.
“We’ve seen a lot of stories on the road, but nothing quite like this one, so we’re excited to be here,” Abraham Luna, one of the representatives, told KRBC, of the 105-year-old bacon woman. “Pearl is an inspiration for the community, and her friends and family, so we had to make a special stop here for her today.”
Cantrell’s daughter Anno says that her mother taught them to work hard and think about living everyday they woke up. She never spoke about dying. She is very active and still loves to dance.
This story comes as a challenge to the latest study conducted by the University of Zurich, which clearly states that eating too much bacon elevates the risk for bowel cancer.
The BBC reports, a McGill University Ophthalmology research team has discovered playing the video game Tetris can actually help treat Amblyopia, commonly known as “lazy eye.”
Amblyopia is a condition affecting the nerves that connect the eyes to the brain. One of the eyes sends poorer images to the brain than the other, and as a result, the brain learns to ignore the weaker eye, possibly resulting in loss of vision. (Via NIHOD)
Usually “lazy eye” is treated during childhood by placing a patch over the stronger eye, forcing the weaker one to work harder. (Via Science World Report)
But the McGill University researchers discovered a much more creative way to treat the disorder.
They split eighteen study participants into two groups of nine. Both groups then played Tetris one hour a day for two weeks while wearing specially-designed goggles. (Via Medgadget)
The first group’s goggles let their weaker eye see the falling shapes themselves and showed the background grid to the dominant eye. The second group’s goggles worked the same as an eye patch, forcing the weaker eye to do all the work. (Via Youtube / Spectre255)
The results showed the group which played using both eyes saw greater improvements in vision than the group which only used the weaker eye.
CBS reports the study’s author, Dr. Robert Hess, says the study shows amblyopia is caused by both eyes and teaching the eyes to work together is better than focusing on the weak one. He said: “It’s much better than patching, much more enjoyable, it’s faster and it seems to work better.”
The study suggests this could be a new way to treat the disorder in children, who are much more likely to enjoy playing a video game for an hour than wearing an eyepatch to school every day.
Is it possible to boost your brainpower while getting a good night’s sleep? Well according to
a study it is by listening to music!
According to a new study if you have music that’s in sync with brain oscillations, or the repetitive rhythm that represents activity, can help improve your memory. (Via ScienceDirect)
According to the Daily Mail, researchers have known for a while that slow brain oscillations are important to retain memory. Now, sound can be used to improve those oscillations.
“Researchers say slow rhythms are best and that stimulation that is out of sync doesn’t help. They also say in-sync rhythms can make slow-wave sleeps last longer.” (Via WXYZ)
These conclusions were drawn by researchers in Germany by tested 11 people. They interchanged between sound exposure while sleep and a placebo. Before they went to sleep, the participants memorized word associations. (Via Nature World News)
The researchers discovered after listening to music while sleeping the participants did a better job of remembering the associations than those who didn’t sleep with music. (Via Counsel and Heal)
Medical Daily points out that using music as a research tool is nothing new when it comes to studying the brain.
A recent study showed brain patterns can predict what music people are most likely to buy.
And a 2010 study showed music can be used as therapy for Alzheimer’s disease. (Via PBS)
So, what could come of this new study? In a press release the researchers said the findings could do more in the future than just improve sleep.
“…it might be even used to enhance other brain rhythms with obvious functional significance—like rhythms that occur during wakefulness and are involved in the regulation of attention.”(Via EurakAlert!)
Dr Leo Spaceman
In my opinion, this character, Dr Leo Spaceman (pronounced spatcheman, or just like it sounds, if you prefer…) is the most underrated and least praised in the hit series 30 Rock. His character is played by Chris Parnell.
Here are some highlights from the First Season.
“Dr, I think Tracy Jordan is having badside-effects from his medication.”“Ah, I was afraid this was going to happen……but, what can you do?Medicine is not a science.”
“Dr, we have a product we would like you to give a medical endorsement to.”“I’ll do it!What is it?”
“Dr, is it true that bread eats out your brain?”“We have no way of knowing, because the powerful bread lobby keeps stopping my research!”
“Dr Spaceman, when they check my DNA will they tell me what diseases I might get or help me to remember my ATM pin code?”
