Managing risk together

by Jan Husdal in husdal.com

How do risks in supply relationships and and organizational learning play out in risk management? The idea is that supply chain partners collaborate as a response to uncertainty in the supply and in consequence develop a learning supply chain, in which they share information. ... Read more »

A Few Recent Longevity Study Results

by Reason in Fight Aging!

More genetic and other studies of long-lived people are taking place these days, which means a faster flow of results than has been the case in past years. Part of that can no doubt be attributed to an increased interest in manipulating the aging process in the scientific community, as well as the continually falling cost of the tools needed to run such studies. While perusing PubMed recently, I noticed a few new reports from ongoing longevity studies starting with one from the Leiden Study in t........ Read more »

NIH Study Reveals a Genetic Basis for Stuttering

by Walter Jessen in Highlight HEALTH

Although the root cause(s) of stuttering remain unknown, evidence has accumulated from twin and adoption studies that genetics plays a role. A recent study identified several genes mutated in people with the disorder, including one that has never been previously associated with any human malady.... Read more »

How old was the Olduvai Hominid?

by zinjanthropus in A Primate of Modern Aspect

In 1960, Mary Leaky discovered a set foot bones composed of seven tarsals (in your ankle) and five metatarsals (in the area between your ankle and your toes).  These bones are those of a biped, with the joints reflecting an in-line big toe.  For these bones, the surrounding debate hasn’t been over whether or not [...]...

Do Antidepressants Enhance Stroke Recovery?

by Neuropsych15 in The MacGuffin

A few months ago, in the February issue of Archives of General Psychiatry appeared this study (1) title, "Escitalopram and Enhancement of Cognitive Recovery Following Stroke."The design was simple: a placebo group, an escitalopram group, and a problem solving therapy group (a manual based therapy to treat depression in the medically ill). No patients in this group met diagnostic criteria for Major Depression (so why the PST group?) according to the Hamilton Scale for Depression (HAM-D)........ Read more »

Supercooled liquid gold alloy

by Lars Fischer in EuCheMS 2010 Blog

It’s well-known that many liquid metals can be cooled below their freezing point. This is, scientists assume, due to dense and symmetric, but non-periodic ordering within the liquid. This theory implies that the freezing point of supercooled metal liquids can be controlled, just like crystallization can be induced by a template – all it takes [...]... Read more »

New Zealand’s productivity paradox: Part IV

by Shaun Hendy in A Measure of Science

In this post, I will continue my discussion of Philip McCann’s paper, “Economic geography, globalisation and New Zealand’s productivity paradox” [1]. McCann argues that it is New Zealand’s economic geography that is the reason for its poor productivity performance. In this post I’ll try to sketch some of the underlying ideas from economic geography that [...]... Read more »

Ass-Dragging Caterpillars Evolved from Bullies

by Kelsey in Mauka to Makai

Suppose you’re a caterpillar. You’ve just built yourself a nice home by sewing leaves together with silk and then some jackass invades your turf. How do you defend your home? You could walk right over to that intruder and push him, maybe smack him around a bit or even bite him. Ha! That’d teach [...]... Read more »

Eccentric Exercise - some cool ideas as to why it seems to heal certain tendinopathies (ps, ditch -itis and -osis)

by mc in begin to dig (b2d)

Have you been suffering with some kind of sore tendon/jointy pain? Rotator cuff area, achiles, elbow, forearm, rsi etc etc? Guess what? First we're not alone, but second, just about anything that's been tried to address it has no real evidence to support it working, especially over time. Indeed, as the authors of a 2009 review study put it, "Tendinopathy is common although pathology of this ... Read more »

Increasing corn production for ethanol may increase atmospheric carbon dioxide

by David Raikow in River Continua

The evaluation of large scale scenarios for alternative energy production are exercises in making trade-offs. If the U.S. devotes substantial resources to ethanol production then use of fossil fuels may be reduced, diminishing dependence on foreign oil, in theory. But are there other costs and benefits? Currently ethanol production in the U.S. centers around corn … Read more... Read more »

A Cataclysmic Variable in the Field of the Kepler Mission

by Professor Astronomy in Professor Astronomy




In September of 2008, I was sitting at the controls of the McDonald Observatory 2.1-meter Struve Telescope.  I was there to help some of my colleagues who work on a team associated with NASA's Kepler Mission.  This team, the Kepler Astroseismic Science Consortium, isn't on the lookout for planets.  They are studying the stars themselves, looking for variations in the light from stars caused by sound waves in the star.  The study of these sound waves, known as asteroseismol........

Transcriptome Genetics with HapMap and RNA-Seq

by Daniel Koboldt in Massgenomics

Two papers in Nature this month leverage the power of second-generation sequencing technologies to investigate gene expression variation in human cell lines. By performing RNA-Seq in HapMap cell lines, the authors generated the most extensive gene expression data to date for these samples, and were able to use publicly available HapMap genotypes to associate expression [...]...

Helping kids eat better by changing school lunches (Part 2)

by Dave in The Daily Monthly

Yesterday I discussed two studies on school lunches in California — one showing that students bring lunches from home tended to eat healthier foods, and one showing that kids will keep buying food at school even when the only option is healthy foods.
But both of these studies had flaws. The first study was conducted before [...]... Read more »

Chimpanzees Prefer Fair Play To Reaping An Unjust Reward

by Eric Michael Johnson in The Primate Diaries

A new study shows that chimps sacrifice their own advantage if they earned it unfairly.Image: Owen Booth / Creative Commons

Fairness is the basis of the social contract. As citizens we expect that when we contribute our fair share we should receive our just reward. When social benefits are handed out unequally or when prior agreements are not honored it represents a breach of trust. Based on this, Americans were justifiably outraged when, not just one, but two administrations bailed out the ........ Read more »

How sucker-winged bats hang on

by Laelaps in Laelaps



A Madagascar sucker-footed bat (Myzopoda aurita).



In the tropical forests of Madagascar, there lives a very peculiar kind of bat. While most bats roost by hanging upside-down from cave ceilings or tree branches, the Madagascar sucker-footed bat (Myzopoda aurita) holds itself head-up thanks to a set of adhesive pads on its wings. Nor is it the only bat to do so. Thousands of miles away in the jungles of Central and South America, Spix's disk-winged bat (Thyroptera tricolor) does the same thi........ Read more »

Everything you wanted to know about Hangovers (but were too affraid to ask)

by TwoYaks in Gene Flow

Recently, I read a statement by the American Heart Association about Alcohol, saying that although moderate alcohol reduces your risk of stroke, if you don't already drink you should not begin drinking because drinking raises your risk of cancer. This is an interesting statement, because I think it is incorrect. Cancer is rare, Stroke is common. Even though alcohol increases the probability of ... Read more »

Tracks of Giants Created Dino Death Traps

by Brian Switek in Dinosaur Tracking

Around 160 million years ago, an enormous sauropod dinosaur trudged across an ancient marsh in what is now Xinjiang, China. It was not easy going. The eruption of a nearby volcano coated the area in a layer of ash which formed a thin surface over a morass of mud and volcanic debris, and as it [...]... Read more »
