Washington, Dec 06 : A new study has revealed that while the human brain is in a resting state, patterns of neuronal activity which are associated to specific memories may spontaneously reappear and such recurrences contribute to the stabilization of memory contents.
A team of researchers headed by Nikolai Axmacher performed a memory test on a series of persons while monitoring their brain activity by functional magnetic resonance imaging ( fMRI). The experimental setup comprised several resting states including a nap inside a neuroimaging scanner.
Washington, Dec 6 : A Wendy's employee was arrested after a customer called 911, complaining that she had found a half-smoked blunt in her cheeseburger.
According to the cops, Amy Seiber immediately admitted the blunt was hers, TMZ. com reported.
The police said that Seiber claimed that she had been smoking pot on the job and had misplaced the blunt inside the customer's burger.
The blunt was taken as evidence and she was arrested for possession of marijuana and also immediately fired.
The customer said that Wendy has offered to help pay for her medical bills and even thrown in a 50 dollars gift certificate.
Washington, Dec 6 : Researchers have showed that reducing the amount of sunlight reaching the planet's surface by geoengineering may not undo climate change after all.
Axel Kleidon and Maik Renner of the Max Planck Institute for Biogeochemistry in Jena, Germany, used a simple energy balance model to determine how sensitive the water cycle is to an increase in surface temperature due to a stronger greenhouse effect and to an increase in solar radiation.
They predicted the response of the water cycle for the two cases and found that, in the former, evaporation increases by 2 per cent per degree of warming while in the latter this number reaches 3 per cent.
Washington, Dec. 6 - Researchers have used novel techniques to modify inexpensive imaging devices, like a webcam selling for ten euros and a mobile phone camera, into a mini-microscope.
The resolution of such mini-microscopes was dependent on the pixel size of the sensor, but sufficient for identification of several pathogenic parasites.
Dr. Johan Lundin and Dr. Ewert Linder were able to use the mini-microscopes they constructed to yield images of parasitic worm eggs present in urine and stools of infected individuals.
Washington, Dec. 6 - Researchers have claimed that sharks can comprehend body orientation and therefore know whether humans are facing them or not.
Erich Ritter of the Shark Research Institute and Raid Amin of the University of West Florida said that this ability helps sharks to approach and possibly attack their prey from the blind side - a technique they prefer.
Descriptions of a shark's approach to typical prey, as well as humans, indicate that these predatory fish prefer to avoid the field of vision.
In other words, a shark would tend to approach a person from behind.
Washington, Dec. 6 - A study pinpoints a region of the brain that, when stimulated, causes a person to anticipate a challenge and possess a strong motivation to overcome it.
Lead author Dr. Josef Parvizi, of the Department of Neurology and Neurological Sciences at Stanford University, said that few electrical pulses delivered to a population of brain cells in conscious human individuals give rise to such a high level set of emotions and thoughts associated with a human virtue such as perseverance tells us that our unique human qualities are anchored dearly in the operation of our brain cells.
Washington, Dec. 6 - Twitter has finally hired a woman to its board after being criticized for having lack of diversity in the staff days before filing for its public debut.
The microblogging site has appointed former Pearson Plc Chief Executive Officer Marjorie Scardino, 66, who will be effective immediately.
Scardino thanked in her first-ever tweet and said that there couldn't be a more exiting time in Twitter's history to join, Washington Times reports.
Washington, Dec. 6 - A new research into the discovery of partial skeleton, suggests that the human ancestor characterized by "robust" jaw and skull bones was a muscular creature with a gorilla-like upper body, and more adaptive to its environment than previously believed.
Researchers found a partial skeleton-including arm, hand, leg and foot fragments-dated to 1.34 million years old and belonging to Paranthropus boisei at the Olduvai Gorge World Heritage fossil site in Tanzania.
Washington, Dec. 6 - Researchers have claimed that caffeine shortens and alcohol lengthens telomeres - the end points of chromosomal DNA, implicated in aging and cancer.
Now Prof. Martin Kupiec said that for the first time they've identified a few environmental factors that alter telomere length, and they've shown how they do it.
Telomeres, made of DNA and proteins, mark the ends of the strands of DNA in our chromosomes. They are essential to ensuring that the DNA strands are repaired and copied correctly.
Washington, Dec. 6 - Astronomers, using Suprime-Cam, Subaru Telescope's wide-field, prime-focus camera, have managed to capture an image of the intricate flow of Comet Lovejoy's (C/2013 R1) ion tail.
The instrument's combination of a wide field of view and high spatial resolution provides a clear delineation of the complex, wiggling streams in the comet's tail.
At the time of this observation, at around 5:30 am on December 3, 2013 (Hawaii Standard Time), Comet Lovejoy was 50 million miles
(80 million km) distant from Earth and 80 million miles (130 million km) away from the Sun.
Washington, Dec. 6 - Samsung has reportedly patented a technology for a transparent touchscreen that would allow users to control the smartphone from both the sides.
This isn't the first time that techies have aimed at exploring the possibilities of having a transparent touch screen as seen recently with the introduction of Yotaphone that has a standard touchscreen on the front and e-paper display on the back.
However, Samsung's patent takes the technology to the next level as it explores the possibility of a transparent screen with front and rear visibility and touch controls.
Washington, Dec 06 - Researchers have found that certain mosquito nerve cells, known as cpA neurons, cause mosquitoes to be attracted to humans by detecting exhaled carbon dioxide (CO2) and odors emitted from human skin.
The study by scientists at the University of California, Riverside may have implications for the control of mosquitoes and the diseases they transmit.
Washington, Dec. 06 - Former South African President Nelson Mandela, who passed away last night following recurring lung infection, had remained on the United States terrorism watch list until 2008.
South Africa's apartheid regime had designated Mandela's African National Congress (ANC) as a terrorist organization for its battle against the nation's legalized system of racial segregation that lasted from 1948 to 1994, the Huffington Post reports.
Washington, Dec. 6 - The ChemCam laser instrument aboard NASA's Curiosity rover recently fired its 100,000th shot.
ChemCam zaps rocks with a high-powered laser to determine their composition and carries a camera that can survey the Martian landscape.
Washington, Dec. 6 - Researchers have shown that by creating two entangled black holes, then pulling them apart, they formed a wormhole-essentially a "shortcut" through the universe-connecting the distant black holes.
Now an MIT physicist has found that, looked at through the lens of string theory, the creation of two entangled quarks-the building blocks of matter-simultaneously gives rise to a wormhole connecting the pair.
The theoretical results bolster the relatively new and exciting idea that the laws of gravity holding together the universe may not be fundamental, but arise from something else: quantum entanglement.
Washington, Dec 06 - Researchers have discovered that many of the endangered great white shark's proteins involved in an array of different functions- including metabolism- match humans more closely than they do zebrafish, the quintessential fish model.
The study by Michael Stanhope , professor of evolutionary genomics at Cornell's College of Veterinary Medicine, lays the foundation for genomic exploration of sharks and vastly expands genetic tools for their conservation, said Stanhope.
Washington, Dec 6 - America's first black President, Barack Obama, in a moving and eloquent tribute, remembered South Africa's first black president and anti-apartheid icon Nelson Mandela as "a man who took history in his hands, and bent the arc of the moral universe toward justice."
"We will not likely see the likes of Nelson Mandela again," said Obama on the death Thursday of the South African leader, who inspired by his other idol Indian freedom leader Mahatma Gandhi, led a peaceful struggle against racial oppression.
Washington, Dec. 06 - World leaders are mourning the anti-apartheid hero Nelson Mandela's death, whose soul departed peacefully last night at his home following complications from the recurring lung infection.
South African President Jacob Zuma announced Mandela's death, saying that the nation has lost its greatest son and several have lost a father, Fox News reports.
Zuma said that Mandela will be accorded a full state funeral, the report added.
President Barack Obama called him one of the "most influential, courageous and profoundly good" people to ever have lived.
Washington, Dec 5 : A businesswoman in Long Island in New York is wanting to build a massive 'Chinese Disneyland' in the Catskills.
The Disneyland would include an amusement park, huge mansions and a 'Forbidden City' laid out according to the principles of Feng Shui.
The China City of America scheme could bring thousands of wealthy Chinese immigrants to the town of Thompson, under a federal program that lets foreigners get visas by investing $500,000 in the US, the New York Post reports.
According to the report, the mastermind behind the plan, Sherry Li, said the development would eventually draw six billion dollars in foreign investment.
The designs for China City include a college, 1,000 residences, a Chinese-themed retail center and possibly a casino.
Washington, Dec 5 : A researcher has come up with an 'algorithm' that tags photos based on the relationships that people in images have with each other.
The algorithm uses the name and location of existing photo tags to build a 'relationship graph,' where personal connections in the images are calculated, Mashable reports.
The new method makes it faster and more efficient at tagging pictures.
According to the report, University of Toronto engineering professor Parham Aarabi has been working on the technology since 2005.
