Meet the Government Researcher Trying to Prove the Universe Is a 2D Hologram. Department of Energy physicist Craig Hogan is trying to prove that the universe, including the world we live in and experience every day, is a hologram. His experiment, being run out of a suburb of Chicago using a device called the Holometer, is being used to determine the nature of spacetime. Hogan says that we have no good way to model or describe what makes up spacetime—it’s possible that at a very very tiny scale (on sizes a million times smaller than a single atom), you’ll find some kind of unit that makes it up. Motherboard correspondent Maddie Stone explained the theory in-depth last week, but Hogan told me a bit about his motivation for researching the hypothesis and what it would mean to both physics and the general public if we are, indeed, living in a hologram.

The 55-year trade embargo led by the US made sure that Cuba was mostly where it stayed. Until—maybe—now. The Obama administration has, of course, been trying to normalize relations with the island nation. And last month, during New York Gov.
Andrew Cuomo’s visit to Havana, Roswell Park Cancer Institute finalized an agreement with Cuba’s Center for Molecular Immunology to develop a lung cancer vaccine and begin clinical trials in the US. Essentially, US researchers will bring the Cimavax vaccine stateside and get on track for approval by the Food and Drug Administration. “The chance to evaluate a vaccine like this is a very exciting prospect,” says Candace Johnson, CEO of Roswell Park. How did Cuba end up with a cutting edge immuno-oncology drug? The thing about making such great cigars is, smoking is really, really bad for you. Go Back to Top. Kind Robot Stitches Poor Peeled Grape Back Together. Meet the Newest State of Matter. It's only slightly less exciting than it sounds: a new state of matter. The discovery, which comes courtesy of an international team led by Kosmas Prassides of Tokohu University in Japan, offers a novel material with an unusual combination of properties—insulator, superconductor, metal, magnet.
Of particular interest is the hint of high-temperature superconductivity, something of a materials science holy grail and a persistent physics mystery. So, there are lots of different states of matter. We all know solids, liquids, gases, and, probably, plasmas, but beyond these there's an entire catalog of matter alternatives: Bose–Einstein condensate, degenerate matter, supersolids/superfluids, quark-gluon plasma, etc. The difference is that all those alternatives are lab-created and don't have much place out in the real world of nature. This is what the rubidium atoms do: apply pressure. Image: Prassides et al. Profilaxia pré-exposição. Use camisinha! Por 30 anos, essa foi a única palavra de ordem para prevenir a transmissão do HIV. Não é mais assim. Em 2010, foi publicada uma pesquisa demonstrando, pela primeira vez, que a administração diária de um comprimido de Truvada, para homens que fazem sexo com homens e mulheres transgênero HIV-negativos, reduzia em 92% os índices de novas infecções.
Nesse estudo, cerca de metade dos participantes tomou a medicação irregularmente. Mais tarde, outra pesquisa, agora conduzida entre casais heterossexuais discordantes (apenas um dos parceiros infectado), com níveis superiores de aderência à medicação, mostrou que 75% ficaram protegidos da infecção. Apesar do impacto desses resultados, o uso de medicamentos antivirais como estratégia de pré-exposição gerou controvérsias. Uma série de estudos sobre profilaxia pré-exposição foi discutida na Conferência sobre Retrovírus e Infecções Oportunistas, realizada na última semana de fevereiro deste ano, na cidade de Seattle.
Brain Sarcasm Centre "Totally Found" - Neuroskeptic. A new study published in the journal Neurocase made headlines this week. Headlines like: “Sarcasm Center Found In Brain’s White Matter“. The paper reports that damage to a particular white matter pathway in the brain, the right sagittal stratum, is associated with difficulty in perceiving a sarcastic tone of voice. The authors, studied 24 patients who had suffered white matter damage after a stroke. In some cases, the lesions included the sagittal stratum in the right hemisphere, and these individuals performed worse on a test in which they had to decide whether statements like “This looks like a safe boat!” So – do these findings mean we’ve found the brain’s sarcasm center?
Yeah. Here’s why. So if the sagittal stratum is required for sarcasm perception, its role is to relay information to and from the relevant part of the cortex – and we don’t know where that part is. Also, I’m not sure how solid the result is. Davis CL, Oishi K, Faria AV, Hsu J, Gomez Y, Mori S, & Hillis AE (2015). Cheese Changed The Course Of Western Civilization And Other Facts.
Cheese Changed The Course Of Western Civilization As most milk-haters are wont to point out, early humans did not — or more accurately could not — drink milk. It wasn't until 8,500 years ago that a combination of over-farming, the invention of pottery, and one lazy goat herder inadvertently created a proto-cheese. Early man ate it, and found that it was good.
Eventually, the regular consumption of cheese over the course of a millennia promoted lactose tolerance within those early cultures, and was then carried over to the western world as early man began the migration to Europe. Today, that same migration is still happening in the form of cheese shops in gentrifying neighborhoods. Everyone's Favorite Time Of Day Is 7:00 P.M. It's Friday. You Can Remove A Wasp Infestation With A Shop Vac In the video game, bug-type Pokémon are weak to flying-type Pokémon, so it makes sense that a shop vac, which utilizes the properties of the air, would be super effective in decimating a wasp nest. Are humans getting cleverer? 1 March 2015Last updated at 19:03 ET By William Kremer BBC World Service IQ is rising in many parts of the world. What's behind the change and does it really mean people are cleverer than their grandparents?
It is not unusual for parents to comment that their children are brainier than they are. In doing so, they hide a boastful remark about their offspring behind a self-deprecating one about themselves. The researchers - Peera Wongupparaj, Veena Kumari and Robin Morris at Kings College London - did not themselves ask anyone to sit an IQ test, but they analysed data from 405 previous studies. Focusing on one part of the IQ test, the Raven's Progressive Matrices, they found that on average intelligence has risen the equivalent of 20 IQ points since 1950. The gains have not been evenly spread. The new research is further confirmation of a trend that scientists have been aware of for some time. This is a puzzle not just for the US, but for all countries demonstrating the Flynn Effect. Google's fact-checking bots build vast knowledge bank - tech - 20 August 2014.
Read full article Continue reading page |1|2 The search giant is automatically building Knowledge Vault, a massive database that could give us unprecedented access to the world's facts GOOGLE is building the largest store of knowledge in human history – and it's doing so without any human help. Instead, Knowledge Vault autonomously gathers and merges information from across the web into a single base of facts about the world, and the people and objects in it. The breadth and accuracy of this gathered knowledge is already becoming the foundation of systems that allow robots and smartphones to understand what people ask them. Knowledge Vault is a type of "knowledge base" – a system that stores information so that machines as well as people can read it.
This existing base, called Knowledge Graph, relies on crowdsourcing to expand its information. So Google decided it needed to automate the process. Knowledge Vault has pulled in 1.6 billion facts to date. Knowledge vault More From New Scientist. Google wants to rank websites based on facts not links - 28 February 2015. The trustworthiness of a web page might help it rise up Google's rankings if the search giant starts to measure quality by facts, not just links THE internet is stuffed with garbage. Anti-vaccination websites make the front page of Google, and fact-free "news" stories spread like wildfire. Google has devised a fix – rank websites according to their truthfulness.
Google's search engine currently uses the number of incoming links to a web page as a proxy for quality, determining where it appears in search results. So pages that many other sites link to are ranked higher. This system has brought us the search engine as we know it today, but the downside is that websites full of misinformation can rise up the rankings, if enough people link to them. A Google research team is adapting that model to measure the trustworthiness of a page, rather than its reputation across the web. There are already lots of apps that try to help internet users unearth the truth. New Scientist Not just a website! Schizophrenia Caused by the Very Genes that Make Us Human. The mental illness question can be further refined to this: as cancer is the cost of human adaptability (in the form of genetic mutation), is mental illness the cost of intellect?
We may have suburb cognitive capabilities thanks to deep neurological complexity, but that same complexity fosters the semiregular occurrence of debilitating illness. No free rides. But it’s not quite that easy. There’s another side to the question, implicating schizophrenia in particular. This is an illness that’s been with humans since the very beginning—when humans became humans—while not really having an analog in other species, even reasonably complex ones. Why has something so disadvantageous to survival (for sufferers, offering an unemployment rate near 50 percent and suicide-attempt rate of near 40 percent) persisted in our DNA? The genes that allow for human intelligence are very closely tied to those implicated in schizophrenia The paradox soon becomes clear.
When Time Flows Backwards. We are doomed to time because of organization. We have pasts, which are just spaces of non-possibility. The past for us is a fixed guideway, a steady elimination of options culminating in this here Why should it be so? Well, causality for one. We're strung along in a generally forward direction by things occurring that cause other things to happen or cause other things to be much more likely to happen. It would seem that the alternative is for nothing to ever happen at all, leaving us to just stand there staring at the departures board, never choosing but never really happening either.
So, that's life, but our lived reality is hardly everything. A consequence of time as space is retrocausality, in which is the future is free to influence the past. The general idea being probed by Murch and his team is properly called post-selection. That's just what it is to be indeterminate. The objective world simply is, it does not happen. Murch's results aren't some kind of one-off. New Measurements Show that the Unrealest Part of Quantum Physics Is Very Real. Subatomic particle-points in the quantum world like to behave as clouds of possibilities (waves) rather than points, a feature of “wave-particle duality,” and the interpretation of this is an open question and a source of great discomfort among physicists. The new research suggests it may just turn out that weirdest part of it is really as strange and counterintuitive as it looks.
Some background: Quantum physics and all of its apparent oddities and quirks boil down to waves. Reality, when left to its own devices, is indeterminate. Image: uoregon.edu All of this probability is given by wave functions, which are really, truly the most important thing. Matt Liefer, a researcher at the Perimeter Institute for Theoretical Physics in Ontario, has a good explanation of the whole wave function/reality mess on his website. If particles exist as real, determinate entities when we measure them, we have to ask what the wave was in the first place. Image: Wikimedia Commons. Have a scientific problem? Steal an answer from nature. The Cold War has been over for decades, but in the dark, frigid waters deep under the oceans, nuclear armed submarines still ply their grim patrol.
These instruments of war are pinnacles of advanced engineering. They are propelled by nuclear reactors; they slide through the depths in near silence; they can remain submerged for weeks, making drinking water from the sea and creating their own breathable atmosphere. While patrolling in total darkness, these vessels are fully aware of their environment, maintaining a map of the natural world around them and any potential adversaries. Although the systems integrated into submarines represent the most advanced fruits of human ingenuity in science and engineering, many of them have origins that are millions of years old. Subs exploit ideas generated not in the brains of men and women, but by the directionless forces of biological evolution itself. Before understanding how we steal from nature, it's important to know why we would want to.
Forget the Super Bowl, Microbes Are Playing Sports in Outer Space. announced the winners Project MERCCURI, the cheerleader-driven effort to understand how microbes behave in space, has just released the results of a competition that’s been brewing at the International Space Station for the past nine months. Now we know which bacteria, amongst forty eight elite contestants drafted from a pool of hundreds, are planet Earth’s finest in terms of growth rates, endurance, and team spirit. “Our core mission is really to convey to the public that microbes are everywhere, and they’re not all bad,” David Coil, a microbial ecologist at UC Davis, andalead scientist behind Project MERCCURI, told me over the phone.
“By engaging sports fans, we’re attempting to reach out to people who might not otherwise spend time thinking about microbiology.” Virtually every structure humans build is swiftly overtaken by literally trillions of unseen bacteria. There’s good cause to suspect that spaceflight might influence Earth’s smallest inhabitants. Project MERCCURI. A New Mathematical Proof Shows How Some Spaces Can't Always Be Divided. Zeno's arrow Where does the halving stop and the face-splitting begin? Ignoring the IRL restriction of the Planck length, why should these divisions ever stop? And if they never stop, does that mean the arrow never reaches its destination?
How does anything ever reach its destination? The arrow and everything else must be motionless. That's some dorm room philosophizing for sure, but Zeno's paradox offers a way into the triangulation of spaces. What about other spaces? In other words, some spaces can't be cut. Image: Harvard.edu What we're really talking about is what's known as an invariant. At Quanta, Kevin Hartnett explains it as such: To find the Euler characteristic of a two-dimensional surface, first divide it into any number of polygons.
The problem with this division, at least among some manifolds, is that the first geometric divisions made don't necessarily match up with the last ones, like trying to match up two halves of two different zippers.
