Watch Uranium Emit Radiation. You’ve heard of the catastrophic effects of radiation on environments, animals and humans. A seemingly silent and invisible destroyer, radiation can make whole cities inhabitable for hundreds of years. But have you ever wondered what radiation actually looks like? There may be one image that jumps to mind. The Simpsons/FOX If you’re curious about what it really does look like, the guys and girls over at CloudyLabs have made a video showing a small piece of uranium mineral sitting in a cloud chamber – a sealed glass container cooled to -40°C (-40°F) – topped with a layer of liquid alcohol, in the process of decay and radiation emission.
CloudyLabs explains exactly what you're seeing, "most of the vapor condenses on the glass surface creating a mist, but a small fraction of it stays in vapour form above the cold condenser. Have a look at the full video here: Our Inner Viruses: Forty Million Years In the Making. Each year, billions of people get infected with viruses–with common ones like influenza and cold viruses, and rarer ones like polio and Ebola.
The viruses don’t stay all that long inside of us. In most cases, our immune systems wipe them out, except for a few refugees that manage to escape to a new host and keep their species alive. In some cases, the viruses kill their unfortunate hosts, and end their own existence as well. But in some exquisitely rare cases, viruses meld with the genome of their hosts and become part of the genetic legacy their hosts pass down to future generations. Scientists know this melding has happened because viruses have distinctive genes. When scientists scan the human genome, they sometimes come across a stretch of DNA that bears the hallmarks of viruses.
The easiest type of virus to recognize are retroviruses, a group that includes HIV. Most of the time, retroviruses behave like other viruses, jumping from host to host.

The plan is for the Perlan Glider to soar 90,000 feet above the earth in 2016 — without an engine. (Courtesy: Perlan Project and Airbus Group) If you thought that flying in the earth’s stratosphere requires super-powerful engines, think again. The new Perlan 2 Glider, which completed its first-ever test flight on Sept. 23 in Redmond, Oregon, is a tiny engineless aircraft that’s designed to reach the edge of space by “surfing” the strong air currents of the Polar Vortex. (Yes, the same Polar Vortex that everyone was talking about last winter.) The first test flight — in which the aircraft flew at a very modest 5,000 feet — was just the start. The upcoming goal is to complete a mission in July 2016 in which the Perlan Glider will sail along at 90,000 feet above the earth — at the edge of space — to make it the highest-flying winged aircraft ever.
To put that in context, the current world record is 85,069 feet held by the SR-71 Blackbird, which reached that altitude in July 1976. Educational Tree of Life Homepage. Newly Risen From Yeast: THC. Photo In August, researchers announced they had genetically engineered yeast to produce the powerful painkiller hydrocodone. Now comes the perhaps inevitable sequel: Scientists have created yeasts that can make important constituents of marijuana, including the main psychoactive compound, tetrahydrocannabinol, or THC. Synthetic versions of THC are available in pill form under brand names like Marinol and Cesamet; they are generally used to treat nausea, and caused by infection or . Genetically modified yeast could make THC in a cheaper and more streamlined way than traditional chemical synthesis.
Using yeast could also shed light on the clinical usefulness of cannabis-derived compounds. Continue reading the main story Video “This is something that could literally change the lives of millions of people,” said Kevin Chen, the chief executive of Hyasynth Bio, a company working to create yeasts that produce THC and cannabidiol, another marijuana compound of medicinal interest.

A remarkable experiment has successfully seen the effects of “quantum motion” at a relatively large scale. These are essentially tiny vibrations caused on an atomic level when an object otherwise appears to be stationary. Among its many implications, the research – which was also able to temporarily stop the effect – could aid the hunt for elusive ripples in space-time called gravitational waves.
The study, published in the journal Science, was carried out by a team of researchers from the California Institute of Technology (Caltech) and collaborators. In classical physics, an object – such as a ball in a bowl – will eventually come to rest as the forces of gravity and friction act upon it. But in quantum mechanics, which governs the behavior of matter and light at an atomic scale, nothing is ever truly at rest. This means that everything has an extremely small quantum noise, or motion; tiny vibrations at an atomic scale. Untitled. Author Affiliations Edited by David M. Karl, University of Hawaii, Honolulu, HI, and approved August 4, 2015 (received for review March 7, 2015) Significance We provide biogeochemical, micropaleontological, and petrological constraints on a subseafloor habitat at the passive Iberia Margin, where mixing of reduced hydrothermal serpentinization fluids with oxic seawater provided the energy and substrates for metabolic reactions.
Abstract Subseafloor mixing of reduced hydrothermal fluids with seawater is believed to provide the energy and substrates needed to support deep chemolithoautotrophic life in the hydrated oceanic mantle (i.e., serpentinite).

Building Blocks Of Life Found Under The Seafloor. Researchers have found the building blocks of life deep below the seafloor, adding evidence to the theory that life is able to spring up wherever there is water, and of course the right chemistry.
The study, published in the Proceedings of the National Academy of Sciences, could have implications for the chances of life existing on other worlds, such as Jupiter’s moon Europa. The team of scientists, from the Woods Hole Oceanographic Institution (WHOI), Virginia Tech, and the University of Bremen in Germany, studied rock samples that had been gathered from the seafloor off the coast of Spain and Portugal in 1993, originating from 100 million years ago in the Early Cretaceous period. Analysis revealed that the rocks were rich in lipids, proteins and amino acids – the building blocks of life. It suggests that the interaction of the mantle with seawater can create the potential for life, and shows that life can spring up in a variety of environments.
But the research is promising. DNA Data Storage Lasts Thousands of Years. A few years back, a multinational research team based out of Europe made a startling announcement: They had developed a process for storing massive amounts of digital data in microscopic DNA strands. Theoretically, according to the research, the process could store up to 300,000 terabytes of data in a fraction of an ounce of DNA — which could last for thousands of years.
By comparison, today’s most powerful desktop hard drives hold around 6 terabytes of data, and might last 50 years. Brainwaves, Heartbeat, DNA Turned Into Music This week, the researchers moved their theory a few steps closer to practical application. The passage of time was approximated by embedding the DNA is silica spheres and heating it up to 160 degrees Fahrenheit for one week. The encoded DNA contained only a small amount of data — about 80 kilobytes of text from the work of Archimedes and Swiss National Charter.

Credit: Andrew Maxwell Phineas Jones, University of Guelph Researchers have claimed that they have identified the compounds in sweetgrass that repel mosquitoes. Researchers at the University of Guelph and the University of Mississippi investigated the components of plants used in traditional therapies and found that in their search for new insect repellents, folk remedies have provided good leads. Lead researcher Charles Cantrell said that sweetgrass gave off a sweet aroma that repels mosquitoes. The researchers filled small vials with a red-coloured feeding solution that mimicked human blood and covered the vials with a thin membrane. The researchers observed what the insects did by counting how many mosquitoes went for a bite of each type of 'blood' vat.
Researchers find intestinal symbionts induce distinct T-regulator cells. (Medical Xpress)—The body's subpopulation of T-regulatory (Treg) cells modulates the immune system, helps the body to recognize and tolerate self-antigens, and is believed to be responsible for the abrogation of autoimmune disease. Recently, immunology researchers have reported in the journal Science that symbionts of the gut microbiota induce a distinct population of T-regulatory cells that express the transcription factor Foxp3. This Treg population constrains immuno-inflammatory responses in the gut, and is induced by a specific array of bacterial species.
Unexpectedly, this induction requires a transcription factor called RORγ, which has previously been known to antagonize the Foxp3 transcription factor in other contexts. The authors point out that Treg cells in various kinds of tissue serve varying purposes beyond immuno-regulatory functions; those found in visceral adipose fat tissue, for instance, regulate metabolic parameters. Scientists Sequence Genome of California Two-Spot Octopus. An international team of genetic researchers from Japan and the United States has sequenced and analyzed the genome of the common California two-spot octopus (Octopus bimaculoides), making it the first cephalopod ever to be fully sequenced.

The team, led by Dr Clifton Ragsdale from the University of Chicago and Prof Daniel Rokhsar from the Okinawa Institute of Science and Technology Graduate University, discovered striking differences between the genomes of the octopus and other invertebrates.
“The octopus appears to be utterly different from all other animals, even other mollusks, with its eight prehensile arms, its large brain and its clever problem-solving capabilities,” said Dr Ragsdale, who is a co-author of a paper published in the journal Nature. “The late British zoologist Martin Wells said the octopus is an alien.

The “supersymmetry” theory has just been dealt another blow by the Large Hadron Collider (LHC). New data from ultra-high-speed proton collisions has provided fresh evidence of subatomic activity and this new insight is consistent with the mainstream Standard Model of particle physics. To understand the significance of these results, it’s important to go back to the basics.
The Standard Model describes the fundamental particles that make up the universe and how they interact. It’s currently one of the best descriptions of the subatomic world, according to CERN, but there are some glaring gaps in information. It can’t describe gravity, can’t explain why there is dark matter, and can't predict the mass of the Higgs Boson. There are extensions to the Standard Model and researchers are looking for discrepancies within it that could be indications of new physics. In the findings, published in the journal Nature Physics, the measurements didn’t show any right-handed coupling. Globe-trotting researchers make a mark with their work. A succession of bibliometric studies carried out in recent years suggest that international collaboration has a significant positive effect on the quality of research. For instance, Elsevier’s report International Comparative Performance of the UK Research Base – 2011, carried out for the Department for Business, Innovation and Skills, reveals that the 46 per cent of UK academics who published with overseas collaborators in 2010 garnered twice as many citations for their papers as those who collaborated only within their institution.
They also had 40 per cent more citations than those who collaborated with academics at other institutions in the UK. But why is the UK so internationally collaborative? According to the 2013 edition of Elsevier’s annual report, the key reason is that researchers in the UK are highly internationally mobile. Elsevier examined the institutional addresses listed on papers in the Scopus database.

You Should Be. 5 simple chemistry facts that everyone should understand before talking about science | The Logic of Science. One of the most ludicrous things about the anti-science movement is the enormous number of arguments that are based on a lack of knowledge about high school level chemistry.
These chemistry facts are so elementary and fundamental to science that the anti-scientists’ positions can only be described as willful ignorance, and these arguments once again demonstrate that despite all of the claims of being “informed free-thinkers,” anti-scientists are nothing more than uninformed (or misinformed) science deniers. Therefore, in this post I am going to explain five rudimentary facts about chemistry that you must grasp before you are even remotely qualified to make an informed decision about medicines, vaccines, food, etc. 1).
Everything is made of chemicals This seems like a simple concept, but many people seem to struggle greatly with it, so let’s get this straight: all matter is made of chemicals. You consist entirely of chemicals. A “chemical-free lifestyle” is totally impossible. 2). 3).
Pseudoscience. Scientists Create Solid Light. On a late summer afternoon it can seem like sunlight has turned to honey, but could liquid—or even solid—light be more than a piece of poetry? Princeton University electrical engineers say not only is it possible, they’ve already made it happen. In Physical Review X, the researchers reveal that they have locked individual photons together so that they become like a solid object.
"It's something that we have never seen before," says Dr. Andrew Houck, an associate professor of electrical engineering and one of the researchers. "This is a new behavior for light. " The researchers constructed what they call an “artificial atom” made of 100 billion atoms engineered to act like a single unit. As some of the photons leaked into the surrounding environment, the oscillations slowed and at a critical point started producing quantum divergent behavior. As cool as it is to produce solidified light, the team was not acting out of curiosity alone. Core Truths: 10 Common GMO Claims Debunked.
