4:31 PM | Migraine Headaches And Carpal Tunnel Syndrome Linked
Patients with carpal tunnel syndrome are more than twice as likely to have migraine headaches, according to data derived from nearly 26,000 Americans responding to a national health survey. Among other questions, participants were asked whether they had had carpal tunnel syndrome during the past year or "severe headache or migraine" during the past three months. Patients with carpal tunnel syndrome have symptoms such as hand numbness and weakness, resulting from pressure on the median nerve in […]

4:23 PM | Cosmic Building Block Dust From An Ancient Supernova Found
One of astronomy's big questions is why galaxies forming as recently as 1 billion years after the Big Bang contain so much dust. The leading hypothesis is that supernovae, stars that explode at the end of their lives, contain large amounts of metal-enriched material that, in turn, harbors key ingredients of dust, like silicon, iron and carbon.read more

4:09 PM | Geoengineering: Ocean Pipes Would Make Climate Worse
To combat possible climate change due to greenhouse gases, a mix of alternative energy sources (except nuclear for the United States) and geoengineering schemes have been proposed. One idea proposes that ocean pipes could facilitate direct physical cooling of the surface ocean by replacing warm surface ocean waters with colder, deeper waters. A new study from a group of Carnegie scientists determines that these types of pipes could actually increase global warming quite

4:00 PM | Nova Vulpeculae 1670 - Colliding Stars Explain 17th Century Explosion
In 1670, the greatest astronomers, including Cassini and Hevelius, the father of lunar cartography, documented the appearance of a new star in the skies. Hevelius described it as nova sub capite Cygni — a new star below the head of the Swan — and now it is officially known it by the name Nova Vulpeculae 1670.  It lies within the boundaries of the modern constellation of Vulpecula (The Fox), just across the border from Cygnus (The Swan) and is also referred to as Nova Vul 1670 […]

3:55 PM | Why Alcoholics Anonymous Works
A journalistic piece entitled,  “The Irrationality of Alcoholics Anonymous “, written by  Gabrielle Glaser, also harshly criticizes Alcoholics Anonymous. AA and similar 12-step programs. I cite a blog on her criticisms here (1) Why Alcoholics Anonymous Works “Glaser’s central claim is that there’s no rigorous scientific evidence that AA and other 12-step programs work. First, she […]

3:24 PM | Chromothripsis: Birth Defects May Be Caused By Chromosome Shattering
In a complex system like the human body, it's no surprise things can sometimes go wrong in development but evolution has made the system rather forgiving. When children inherit chromosomes from their parents, some minor genetic changes frequently occur without consequence but chromothripsis - chromosomal shattering - has been linked to severly affected children of healthy mothers in a small study.read more

2:34 PM | Komodo Dragons: Their Bite is Worse than Their Bark
By Shelly Sonsalla Komodo Dragon. Image by Arturo de Frias Marques on Wikimedia. Komodo dragons are the world’s largest living lizard and can be found only on select islands in the Indonesian archipelago. These massive lizards can grow to be 10 feet in length and up to 150 pounds! Their natural prey includes wild boars, deer, and water buffalo—animals which may outweigh them by several hundred pounds. So how does a lizard, even such a large one, manage to take down prey so […]

12:00 PM | Evolution Of The Dorso-Ventral Axis In Humans Revealed
Most animals have a dorso-ventral (back-to-belly) body axis which determines the position of the central nervous system - dorsal in humans, ventral in insects. Though there are obviously morphological differences, the same signaling molecules of bone morphogenetic protein (BMP) molecules establishes the dorso-ventral axis including the central nervous system in both insects and vertebrates, which led to the conclusion that this molecular mechanism was already present in the common […]

11:47 AM | Sting Shows Supplement Regulation Worthless
It seems that the regulation of supplements, homeopathy, and “natural” products in Canada is as bad as the US. The Canadian Broadcasting Corporation (CBC, the equivalent of NPR and PBS in the US) recently conducted a demonstration of just how worthless and deceptive the regulations are. They created a fake treatment called “Nighton” which they [...]

11:41 AM | Spring Flukes: New 3-Sigma Signals From LHCb And ATLAS
Spring is finally in, and with it the great expectations for a new run of the Large Hadron Collider, which will restart in a month or so with a 62.5% increase in center of mass energy of the proton-proton collisions it produces: 13 TeV. At 13 TeV, the production of a 2-TeV Z' boson, say, would not be so terribly rare, making a signal soon visible in the data that ATLAS and CMS are eager to collect.read more

9:24 AM | Team effectiveness is disproportionately influenced by your group's best performer or "extra miler"
The quality of a team's best performer (the "extra miler") is diagnostic of the group's overall effectiveness.In The Hobbit, fifteen companions come together on a quest for a dragon’s treasure. Traditional team analysis would judge "Thorin and Company" on the sum of its parts: Ori is stalwart, and Dori strongly stalwart, and, ok, Bifur seems stalwart enough … a fairly stalwart team, then. But we’re beginning to understand that single individuals can have a […]

4:48 AM | Massive Amounts Of Fresh Water, Glacial Melt Pouring Into Gulf Of Alaska
Incessant mountain rain, snow and melting glaciers in a comparatively small region of land that hugs the southern Alaska coast and empties fresh water into the Gulf of Alaska would create the sixth largest coastal river in the world if it emerged as a single stream, a recent study shows. Since it's broken into literally thousands of small drainages pouring off mountains that rise quickly from sea level over a short distance, the totality of this runoff has received less attention, scientists […]

4:00 AM | A simple model for growing a brain
Today I had a chance to read a paper by Song, Kennedy, and Wang about their model for explaining how brains are wired up at a high level (explaining how areas are connected, not the detailed wiring of neural circuits). It's very simple, but manages to capture some complicated aspects of brain structure. The goal of the model is to offer some explanation for area-to-area connection patterns across species (humans, monkeys, mice). For example, the human connection matrix looks like this (from […]

2:53 AM | Life-saving Treatments Learned From War Are Being Missed
Trauma is responsible for more global deaths annually than HIV, malaria and tuberculosis combined. Yet healthcare systems in many countries are missing out on life-saving treatments learnt on the battlefield, according to a review by King's College London and published today in the Journal of the Royal Society of Medicine. Medical advancements made by the military in times of conflict, are increasingly seen in the hospitals of high income countries but are being missed in poorer countries, […]

7:57 PM | Phase 3 Trial Of Brentuximab Vedotin Shows It Doubles Progression Free Survival In Hodgkin Lymphoma
A phase 3 trial of brentuximab vedotin (BV), the first new drug for Hodgkin lymphoma in over 30 years, shows that adults with hard-to-treat Hodgkin lymphoma given BV immediately after stem cell transplant survived without the disease progressing for twice as long as those given placebo (43 months vs 24 months). The findings, published in The Lancet, are potentially practice changing for this young cancer population who have exhausted other treatment options and for whom prognosis is poor. "No […]
