8:26 AM | Immune cells to be tested on the International Space Station
The human body is fine-tuned to Earth’s gravity. Scientists are now conducting an experiment on the International Space Station (ISS) to study whether this also applies to human cells. We know the effect of gravity on muscles, bones and joints inside out; it has been studied extensively in medicine for centuries. For a long time, …

8:24 AM | A cross-section of the universe
An image of a galaxy cluster taken by the NASA/ESA Hubble Space Telescope gives a remarkable cross-section of the Universe, showing objects at different distances and stages in cosmic history. They range from cosmic near neighbours to objects seen in the early years of the Universe. The 14-hour exposure shows objects around a billion times …

8:20 AM | NASA Cassini images may reveal birth of a Saturn moon
NASA’s Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon, and may also provide clues to the formation of the planet’s known moons. Images taken with Cassini’s narrow angle camera on April 15, 2013, show disturbances at the very edge of Saturn’s …

8:13 AM | How are we different and what gave us the advantage over extinct types of humans like the Neanderthals?
n parallel with modern man (Homo sapiens), there were other, extinct types of humans with whom we lived side by side, such as Neanderthals and the recently discovered Denisovans of Siberia. Yet only Homo sapiens survived. What was it in our genetic makeup that gave us the advantage? The truth is that little is known …

8:10 AM | First Eurasians left Africa up to 130,000 years ago
A team of researchers led by the University of Tübingen’s Professor Katerina Harvati has shown that anatomically modern humans spread from Africa to Asia and Europe in several migratory movements. The first ancestors of today’s non-African peoples probably took a southern route through the Arabian Peninsula as early as 130,000 years ago, the researchers found. …

8:05 AM | The Science of Persuasion
A while ago I wrote several blogs looking at how a knowledge of psychology can be used to persuade us to do things (e.g. here and here). Recently I came across the following animated presentation which concisely and cleverly describes key methods of persuasion.

8:04 AM | A plague in your family: A plague in your family The independent evolution of harmful organisms from one bacterial family
For the first time, researchers have studied the Black Death bacterium’s entire family tree to fully understand how some of the family members evolve to become harmful. Contrary to popular belief, the team found pathogenic members of this bacterial family do not share a recent common disease-causing ancestor, but instead, have followed parallel evolutionary paths …

8:00 AM | Guest Post, pt. 1: Why Are Doctors Skeptical & Unhelpful about Chronic Fatigue Syndrome?
Eight years ago, collapsed on a neurologist’s examining table, I asked a naive question that turned out to be at the center of a controversy continuing to this day. I had just received a diagnosis for the illness that had been gradually overtaking me for the previous six years, and I asked, “So what is […]

7:52 AM | Criticism is not “hate speech”
I sense a new disturbance in the antivaccine force. I hadn’t planned on blogging about the antivaccine movement again, but I felt that I needed to do a follow up to yesterday’s (hopefully) amusing little takedown of the antivaccine stylings of new member of that group personification of the Dunning-Kruger effect and arrogance of ignorance,…

6:29 AM | High School Athletes: 2.5 Million Basketball Injuries In 6 Seasons
Basketball is a popular high school sport in the United States with 1 million participants annually. A recently published study by researchers in the Center for Injury Research and Policy at Nationwide Children's Hospital is the first to compare and describe the occurrence and distribution patterns of basketball-related injuries treated in emergency departments and the high school athletic training setting among adolescents and teens. read more

3:42 AM | Neuroscientists Discover Brain Circuits Involved In Emotion
Neuroscientists have discovered a brain pathway that underlies the emotional behaviours critical for survival. New research by the University of Bristol, published in the Journal of Physiology today [23 April], has identified a chain of neural connections which links central survival circuits to the spinal cord, causing the body to freeze when experiencing fear. Understanding how these central neural pathways work is a fundamental step towards developing effective treatments for emotional […]

3:41 AM | Cougars' Diverse Diet Helped Them Survive The Pleistocene Mass Extinction
Cougars may have survived the mass extinction that took place about 12,000 years ago because they were not particular about what they ate, unlike their more finicky cousins--the saber-tooth cat and American lion. Both perished along with the woolly mammoth and many of the other supersized mammals that walked the Earth during the late Pleistocene. That is the conclusion of a new analysis of the microscopic wear marks on the teeth of cougars, saber-tooth cats and American lions described in the […]

3:28 AM | What I learned this Earth Day, 2014
Laura Nielsen for Frontier Scientists – In the summer I drive to my favorite of many nearby glacial lakes, a deep down-turned gumdrop of cool water ringed in lillypads. I catch painted box turtles. After a frenetic chase and what feels like too long without air I surface gasping, and marveling at each turtle’s personality. They might battle hissing and clawing at air, or hide a bit before emerging to inspect me… or their own reflections in my goggles. Some... Read more

2:33 AM | April 22, 2014 Solar Panel Lantern and Individual Project Update
During today’s session, I attempted to prototype my solar panel lantern circuit.  I started from scratch, with only a breadboard and a couple wires. I took the advice from Simon to say the circuit out loud and split the circuit into different parts. Without much success, I started to see flaws in my circuit. One […]

11:58 PM | Mantis Shrimp: Cool Eyes, And Stronger Than Airplanes
Inspired by the fist-like club of a mantis shrimp, researchers have developed a design structure for composite materials that is more impact resistant and tougher than the standard used in airplanes. The peacock mantis shrimp, or stomatopod, is a 4- to 6-inch-long rainbow-colored crustacean with a fist-like club that accelerates underwater faster than a 22-caliber bullet. Researchers, led by Kisailus, an associate professor of chemical engineering, are interested in the club because it can […]

11:00 PM | 32 Percent Of Canadian Adults Say They Were Abused As Kids
Canadians may seem polite to outsiders, that maple leaf on a backpack says pacificism all over the world, but they are apparently quite hard on their kids. ACanadian Medical Association Journal articles says that almost one-third of adults in Canada have experienced sexual abuse, child abuse or been exposed to intimate partner violence, such as parental, step-parental or guardian violence in their home. Child abuse has been linked to mental disorders and suicidal ideation (thoughts) or […]

10:34 PM | A Crack In The Cosmic Egg - What Does The Cosmic Inflation Discovery Really Mean?
Last month, scientists announced the first hard evidence for cosmic inflation, the process by which the infant universe swelled from microscopic to cosmic size in an instant. While this almost unimaginably fast expansion was theorized more than three decades ago, there had been no evidence. Then researchers from the BICEP2 collaboration announced the first direct evidence for cosmic inflation and the first images of gravitational waves, or ripples in space-time, described as the "first tremors […]

  "To know that no one before you has seen an organ you are examining, to trace relationships that have occurred to no one before, to immerse yourself in the wondrous crystalline world of the microscope, where silence reigns, circumscribed by its own horizon, a blindingly white arena — all this is so enticing that I cannot describe it." - Vladimir Nabokov, born on this day, April 22, 1899 Such a beautiful description of the pleasure of investigation, capturing the intensely […]

10:30 PM | On Discovering A Butterfly
On Discovering A Butterfly: Happy birthday to lepidopterist and sometimes writer Vladimir Nabokov! Well, he might be a bit more famous for the writing thing, come to think of it, but I’m convinced that science was his true passion. Celebrate with one of his poems, an ode to taxonomy: I found it in a legendary landall rocks and lavender and tufted grass,where it was settled on some sodden sandhard by the torrent of a mountain pass. The features it combines mark it as newto science shape […]
