Curiosity will find tridymite on Mars. Photograph: Nasa March spacecraft Curiosity has made an unexpected mineral discoveries on the Red Planet - tridymite. The silicon-oxygen-rich minerals have been found, for example, the volcano St. Helens in the Pacific Northwest. - The discovery of tridymite was completely unexpected, said Doug Ming at NASA. The discovery has been published in the scientific journal Proceedings. Scientists ask the question whether Mars has had a much more violent volcanic activity when the planet was formed than previously thought.
These days, the drug is primarily used to treat methemoglobinemia, a disease that affects the ability of soft tissue to absorb oxygen from the bloodstream, but a new study suggests it may have some exciting uses for improving memory and attention.The small study was published by the Radiological Society of North America and centers around a double-blind, placebo-controlled test of 26 adults, who were given either a single low dose of Methylene Blue or the aformentioned placebo.Using MRIs, the team of doctors measured brain activity as the subjects performed mental tasks.The results were encouraging, as the study says a increase in MRI activity was observed "during sustained attention and short-term memory tasks," in the subjects who took Methylene Blue.The study was performed by doctors at The University of Texas Health Science Center at San Antonio and The University of Texas at Austin.It was published in the scientific journal Radiology by the Radiological Society of North America under the title "Multimodal Randomized Functional MR Imaging of the Effects of Methylene Blue in the Human Brain."
Today, the UK's Wellcome Trust, a major funder of biomedical research, announced that it was partnering with a publisher called F1000 to create a new scientific journal.As its name implies, Wellcome Open Research will exclusively feature the research of people funded by the organization, and it will provide open access for anyone to view it—no subscription required.The journal will also have distinctive twists on what constitutes something worth publishing, as well as the peer review process.Both the underlying technology and the approach to publishing will be borrowed from F1000.Authors will submit a work more on what constitutes a work later , at which point it will undergo a brief editorial check for scientific validity.At that point, peer reviewers will be invited to check the work out; their reviews, as well as their identity, will be public, so that anyone viewing the document can see it.
Being overweight can cost you life, according to a new study. The result contradicts previous findings that demonstrated that a few extra pounds does not involve any greater risk. According to the new study, published in the scientific journal The Lancet, is evidence that the risk of dying before the 70th anniversary increasing "steady and sharp" with an expanding waistline. - On average, lose overweight about a year in the life expectancy, and moderately obese lose about three years, said Emanuele Di Angelantonio from Cambridge. The study is based on a survey of 239 major studies between 1970 and 2015 in 32 countries and is based on data from 3.9 million, after including smokers and those who had a chronic condition at the beginning of the study have been deducted. The study followed participants for an average of 14 years.
The working prototype is part of a decades-long attempt to shrink electronics down to the atomic level, a feat scientists believe would allow them to store information much more efficiently, in less space and more cheaply.Corporations including International Business Machines Corp. IBM -0.19 % and Hewlett Packard Enterprise Co. HPE 0.15 % also have explored research to reduce such space needs.The so-called atomic-scale memory, described in a paper published on Monday in the scientific journal Nature Nanotechnology, can hold one kilobyte, the equivalent of roughly a paragraph of text.It may not sound very impressive, said Franz Himpsel, a professor emeritus of physics at the University of Wisconsin, Madison, who wasn t involved in the study.Most previous attempts at encoding information with atoms, including his own, managed roughly one byte, Dr. Himpsel said.With the new device, we can rewrite it as often as we like, said Sander Otte, an experimental physicist at Delft University of Technology in the Netherlands and the lead author on the new paper.
Copyright Tsafrir Abayov/Leon Levy Expedition A 3,000-year-old graveyard with the bones of about 200 individuals discovered in Ashkelon, Israel, is being hailed as the first and only Philistine cemetery ever found.If valid, the finding would reveal more about a mysterious people known as the Philistines.The conflict between the Philistine giant Goliath and Israel's King David who was armed only with a slingshot is the most famous encounter.However, experts not affiliated with the excavations are not yet convinced of the claim, saying that the identity of the people buried at the Ashkelon cemetery is not clear-cut and the finding itself has not been published in a peer-reviewed scientific journal.See Photos of the Possible Philistine Cemetery and Artifacts
The work at its Connectivity Lab could help bring high-speed Internet to remote areas.Facebook says it has developed a laser detector that could open the airwaves to new high-speed data communications systems that don t require dedicated spectrum or licenses.But traditional wireless comes with speed limitations and requires radio spectrum that often needs to be purchased from the government.Faced with these limitations, engineers have increasingly eyed sending data from point-to-point over laser beams.But sending high speed signals using lasers isn t simple.This reduces the aperture of the system, so a complex pointing and aiming system is required to keep the laser locked onto the receiver.
Zikavirus spread mainly by mosquitoes and, rarely, through sex. Now the virus found alive in the sperm of a man for over three months. Live zikavirus found in the sperm of a man after 93 days. It is 31 days longer than the virus previously shown to survive in semen, shows a new study published in the scientific journal The Lancet. The 27-year-old Frenchman's sperm tested positive for zikavirus in March, three months after he had symptoms of an infection that he should have received during a trip in Thailand. Pregnant women who become infected with Zika has an elevated risk of having a child with microcephaly, for small head and brain.
And we re bullish on the effectiveness of brain chip implants and synthetic blood when it comes to increasing our concentration, intellectual prowess, and physical performance.Most Americans say they would not want to improve their cognitive or physical abilities with brain chips or synthetic blood.Once one person does it, the rest of the pack tends to follow along.General Secretary Gorbachev, if you seek peace, if you seek prosperity for the Soviet Union and Eastern Europe, if you seek liberalization, come here to this gate.For that reason alone, you should read his entertaining piece on the tech scene in Venice. The first study quantifying the global costs of sloth was published Thursday in the scientific journal The Lancet, finding what researchers labeled a conservative estimate of the economic burden caused by inactivity.
Police are asking for clearer laws on the interception, with fake base stations.the Swedish police surveillance with the help of fake base stations becomes all the more problematic because it lacks the support of law.Markus Naarttijärvi is a senior lecturer at the department of law at Umeå university.In an article that is förhandspublicerad online and will be published in the next issue of the scientific journal Computer Law and Security Review, he explores about the Swedish police use of false base stations are compatible with the Echr and EU law.the Fake base stations imsi-catchers, lurking mobiles to connect to them instead of to the mobile operator's base stations or the network.And, according to the Naarttijärvi, some so-called Dirtboxes r & tte-boxes also intercept the content of calls.
The classic model of scientific progress is that the field advances when new findings contradict or supersede old ones.But a new study reveals that this process isn't working today—at least, not in scientific journals, where most data is shared with colleagues.Indeed, the researchers found that "rebuttals scarcely alter scientific perceptions about the original papers."For the study, a group of researchers looked at the citation rates on seven marine biology papers about fisheries.The researchers wanted to know whether these rebuttals affected citation levels on the original papers—and, perhaps more importantly, whether they convinced people to question the interpretation of data in the original papers.It turns out that rebuttals don't seem to affect the scientific community's understanding of the original papers in any way.
Scientists have noticed the tiny trans-Neptunium object emitting X-rays, which, if it is confirmed, is both a baffling and exciting discovery.Carey Lisse and Ralph McNutt from Johns Hopkins University Applied Physics Laboratory and a team of colleagues detected the X-rays by pointing the Chandra X-Ray Obervatory telescope in Pluto s direction four different times between February 2014 and August 2015.Seven photons of X-ray light were detected during these observations, confirming the team s hypothesis that the dwarf planet is detectable on the X-ray spectrum, potentially due to the presence of an atmosphere.Until now, the popular description of the dwarf planet is as a tiny ball of frozen rock slowly meandering around the sun some 3.6-billion miles away.The recent fly-by done by the New Horizons space probe began to call this idea of Pluto into question, as data from the spacecraft s approach of the dwarf planet indicated the presence of an atmosphere.That atmosphere is likely a result of Pluto s icy surfaces slowly melting when it is closer to the sun along certain points of its orbit.
The early-stage textile device could eventually be used for on-the-go charging of smartphones and tablet computers, according to the Chinese researchers who developed the technology."We expect it can be a product for the everyday consumer in the future," two of the researchers, Wenjie Mai of Jinan University and Xing Fan of Chongqing University, told Mashable by email.The researchers published their results Wednesday in ACS Nano, a scientific journal of the American Chemical Society.That's not including the panoply of wristbands, buttons, headsets and sensors that can turn our bodies into walking data centers.The solar-producing fibers wouldn't collect biometric information, but they could potentially address two big challenges facing modern society: How to keep all our devices fully charged, and how to satisfy our energy appetite without burning fossil fuels and emitting planet-warming greenhouse gases."Energy harvesting in general is significant," Paul Weiss, editor-in-chief of ACS Nano and the presidential chair at University of California, Los Angeles, said about the new textile device.
The best character from the 90s sitcom Friends was Joey Tribbiani, and don't even try to argue with me.The womanizing Italian-American actor is simultaneously hilarious and adorable.Which is why it's absolutely right that he was the only cast member to get a slightly questionable spin-off, and why it's right that he's going to be the first TV character to be immortalised as an artificial intelligence.James Charles, Derek Magee and David Hogg from the computer science department at Leeds University are developing a "virtually immortalised" edition of Joey Tribbiani, who they hope you'll soon be able to talk to like you talk to Siri or Alexa.In a paper, which doesn't yet appear to have been peer-reviewed or submitted to a scientific journal, the trio describe their quest to "build virtual talking avatars of characters fully automatically from TV shows"."For many years humans have been enthralled with recording people and their activities using e.g.
Which is this year's scientific breakthrough – the journal Science has selected fifteen Is the discovery of a giant planet in our solar system periphery, Planet X, which is 2016, the greatest scientific breakthrough?Or is it the ultra-thin "super-lens", where a group of researchers at Harvard university in the summer presented a lens as thin as paper?the Journal Science has over 20 years appointed this Year's scientific breakthrough.Now it is time for this year's vote, in which fifteen candidates have been selected by the scientific journal's editorial staff.Voting runs until midnight on Sunday 4 december.
Scientists have been investigating the potential effects of climate change for years.Though many of the predicted changes are now occurring, such as loss of sea ice, accelerated sea level rise, and more extreme heat waves, not all effects are well understood.Most of us are aware that the global temperatures are creeping upward as a result of heat trapped in the atmosphere due to greenhouse gas emissions.In a recent investigation published in the scientific journal Nature, scientists have explored the influence of global warming on soil carbon stocks located in the earth s soil, which is still unclear to the scientific community.Plants, microbes, and animals that live in the soil require exchange of carbon with the atmosphere, resulting in either sequestration of carbon through processes such as photosynthesis or liberation of carbon through processes such as decay.In the most recent investigation, scientists compiled a global database of soil carbon stock responses to global warming using worldwide climate change experiments.
When a young star is born sent a powerful whirlwind.For the first time a svensklett teams are now able to see how these winds are formed.When a star has just been born, a rotating disk of leftover dust and gas is formed around it.this is The content of the disc that eventually is collected in increasingly larger clumps that then become planets.Now, the researchers, who publish their findings in the scientific journal Nature, was able to see how whirlwinds, are formed from the entire disc and for with clouds of gas and dust away from it.We see how the wind, like a tornado lifts up the material and the gas from the spinning disc, where a new solar system being formed, " says Per Bjerkeli, astronomer at Chalmers university of technology and Niels Bohr-institutetet at the university of Copenhagen, who led the research team, in a press release
Imagine reading a study from a prestigious science journal and finding out that the scientists performed and wrote the study as a joke.Other years you might have found it funny.But what if the joke was so arcane that only the scientist got it?Every year around Christmastime, the British Medical Journal releases an issue allowing comically-minded scientists a chance to show off their ability to have a good time.The BMJ has been publishing joke issues for at least 30 years, according to a New York Times report, to add some fun to the otherwise stuffy world of science publishing.The reports are said to meet the same rigorous scientific standards as the rest of the journal s articles but are often more lighthearted in content than the usual output, or produced with comedic intent and contain a dose of sarcasm.
Researchers in South Korea have developed a synthesis method for a new type of graphene that will benefit new applications including seawater desalination, according to Samsung Electronics and Sungkyunkwan University.Samsung Advanced Institute of Technology SAIT researchers and Sunkyunkwan University s advanced materials science and engineering professors have jointly researched the original technology to synthesise the large-area monatomic amorphous graphene allotrope on germanium semiconductor wafers.The study on the new type of graphene, which is non-conductive and super-permeable, is featured in the international scientific journal Science Advances under the title Realisation of continuous Zachariasen carbon monolayer.If an amorphous two-dimensional material that allows penetration of water but not ions is developed, it can be used for seawater desalination, a member of the research team said.Discovered in 2004, graphene is one of the rare known 2D nanomaterials.It has been known to be composed of a hexagonal lattice of carbon atoms.
BOSTON – In a Mexican cave system so beautiful and hot that it is called both Fairyland and hell, scientists have discovered life trapped in crystals that could be 50,000 years old.The bizarre and ancient microbes were found dormant in caves in Naica, Mexico, and were able to exist by living on minerals such as iron and manganese, said Penelope Boston, head of NASA's Astrobiology Institute."It's super life," said Boston, who presented the discovery Friday at the American Association for the Advancement of Science conference in Boston.If confirmed, the find is yet another example of how microbes can survive in extremely punishing conditions on Earth.Though it was presented at a science conference and was the result of nine years of work, the findings haven't yet been published in a scientific journal and haven't been peer reviewed.Boston planned more genetic tests for the microbes she revived both in the lab and on site.
