2:58 AM | Prophecies that Really Come True
The self-fulfilling prophecy is an idea that’s really bugged me for a while, so I thought I should share it with you. I first thought of it when thinking about my favourite juice store. They have ranked their juices in order of popularity so there’s a big poster that says “#1 House Special” that describes their […]

2:32 AM | The Smart Grid: An Energy Solution
The world is racing against the clock, trying to tackle the energy crisis before our resources run out. Lately, scientists have been coming up with new, brilliant ways of saving energy, one of which is the smart grid. The smart grid is actually not that new of a concept, but very few people know of […]

2:05 AM | A Dark Spot on the Sun Seething with Energy
Many of you in North America who saw the partial eclipse of the Sun last Thursday may have noticed a nice dark spot under the eclipsed part of the Sun.  The full "active region" (that the visible spot is part of) is bigger in area than the giant planet Jupiter and has become the largest such feature on the Sun in 24 years.With the kind permission of the photographers, I am posting here a beautiful close-up of the area, by Randall Shivak and Alan Friedman.  Look how wonderfully complex […]

2:00 AM | Witnessing The Exploding Fireball Stage Of A Nova
The expanding thermonuclear fireball of a nova is a staple of movies and fiction but last year one was witnessed in the constellation Delphinus with unprecedented clarity. The observations produced the first images of a nova during the early fireball stage and revealed how the structure of the ejected material evolves as the gas expands and cools. read more

1:41 AM | How To Build A Powerful Antibiotic
Antibiotics are a part of nature, as is antibiotic resistance. A study on how a powerful antibiotic agent gets made in nature solved a decades-old mystery and opens up new avenues of research into thousands of similar molecules. The team focused on a class of compounds that includes dozens with antibiotic properties. The most famous of these is nisin, a natural product in milk that can be synthesized in the lab and is added to foods as a preservative. Nisin has been used to combat food-borne […]

12:15 AM | New Animated Web Series Makes the Theory of Evolution Easy to Understand
When it comes to matters of broad scientific consensus, I’m generally inclined to offer provisional assent. Like everyone else, I have to rely on the expertise of others in matters outside my ken, and in many cases, this rational appeal […]test The post New Animated Web Series Makes the Theory of Evolution Easy to Understand appeared first on Australian Science.

12:05 AM | The Coolest Places on Earth: The Abandoned Town of Kolmanskop, Namibia (Pictures)
In 1908, German railway worker Zacharias Lewala stumbled upon a diamond while working in an area of the Namib Desert in southern Namibia (Namibia was a German colony at that time). After Zacharias informed his supervisor of the find, word quickly spread that the area was rich in diamonds, and German miners began flocking to the area. The diamonds made the first miners very wealthy, so they decided to shape the mining town after a classic German town, complete with a

11:21 PM | Another 5-permutohedron
I've been playing with the Cayley graphs of the symmetric group again, after accidentally running across the Wikipedia article on the icositruncated dodecadodecahedron and thinking "oh yeah, that's the polyhedron that geometrically represents the Cayley graph generated by a transposition and a 4-cycle".Only, it's not. That was a different star polyhedron. So is the icositruncated dodecadodecahedron also a permutohedron? And if so, what are the generators of the corresponding Cayley graph?To […]

9:34 PM | The perfect cup of coffee boils down to four factors
It’s hard to get a bad coffee these days. Plenty of baristas have fine-tuned the process of making espresso, but really there are only a handful of variables they can control: Subject:  Health & Medicine

8:13 PM | Why we remember some things and not others
In a unique imaging study, two Northwestern University researchers have discovered how neurons in the brain might allow some experiences to be remembered while others are forgotten. It turns out, if you want to remember something about your environment, you better involve your dendrites. Using a high-resolution, one-of-a-kind microscope, Daniel A. Dombeck and Mark E. J. Sheffield peered into the brain of a living animal and saw exactly what was happening in individual neurons called […]

8:11 PM | A switch to dampen malignancy
Ludwig Oxford researchers have discovered a key mechanism that governs how cells of the epithelia, the soft lining of inner body cavities, shift between a rigid, highly structured and immobile state and a flexible and motile form. Subject:  Biology & Aging

8:05 PM | New evidence for an exotic, predicted superconducting state
Superconductors and magnetic fields do not usually get along. But a research team led by a Brown University physicist has produced new evidence for an exotic superconducting state, first predicted a half-century ago, that can indeed arise when a superconductor is exposed to a strong magnetic field. "It took 50 years to show that this phenomenon indeed happens," said Vesna Mitrovic, associate professor of physics at Brown University, who led the work. "We have identified the […]

7:07 PM | Artificial pancreas to begin clinical trials
A new medical device that operates like an artificial pancreas is set to begin clinical trials. Overseen by a multi-university team with NIH funding, the device is capable of monitoring blood glucose, delivering insulin responsively, and connecting with a smartphone. Subject:  Health & Medicine

7:01 PM | Research Summary 10/23/14- Microscopes and Lenses
Last week at FSL research we delved into the world of microscopes! After splitting into two teams, we worked to solve a mini mystery while learning how to use the stereomicroscope, testing hair and pen samples to solve the crime. Our next station was an optics activity in which we measured the focal length of […]

6:42 PM | ADHD in Girls (Like me)
You know that kid in your class? The one who is always buzzing with energy or will never stop talking while the teacher delivers yet another boring lecture? The one you jokingly say has ADHD because they can never seem to focus? I’m not that kid, but I have ADHD. Yesterday I went to the […]

6:38 PM | Ebola: Guidelines For Clinicians
Though the Centers for Disease Control has been a little confused about dealing with Ebola, Disaster Medicine and Public Health Preparedness has guidelines for volunteers who want to help.  Some are obvious. If you deal with Ebola patients, quarantine yourself for a little while. People in the bowling alley don't need to know right now that you were with Doctors Without Borders and that you just got back from helping overseas. Common sense is needed, though The World Health Organization […]

6:37 PM | Lizards seen evolving within 15 years
Scientists working on islands in Florida have documented the rapid evolution of a native lizard species — in as little as 15 years — as a result of pressure from an invading lizard species, introduced from Cuba. After contact with the invasive species, the native lizards began perching higher in trees, and, generation after generation, their feet evolved to become better at gripping the thinner, smoother branches found higher up.

6:29 PM | Molecular beacons shine light on how cells "crawl"
Adherent cells, the kind that form the architecture of all multi-cellular organisms, are mechanically engineered with precise forces that allow them to move around and stick to things. Proteins called integrin receptors act like little hands and feet to pull these cells across a surface or to anchor them in place. When groups of these cells are put into a petri dish with a variety of substrates they can sense the differences in the surfaces and they will “crawl” toward […]

6:22 PM | NASA identifies ice cloud above cruising altitude on Titan
NASA scientists have identified an unexpected high-altitude methane ice cloud on Saturn's moon Titan that is similar to exotic clouds found far above Earth's poles. This lofty cloud, imaged by NASA's Cassini spacecraft, was part of the winter cap of condensation over Titan's north pole. Now, eight years after spotting this mysterious bit of atmospheric fluff, researchers have determined that it contains methane ice, which produces a much denser cloud than the ethane ice previously […]
