Measles, Papua New Guinea and the brain

by Connor Bamford in The Rule of 6ix

You may not have realised that – since most people nowadays have been vaccinated against it and have never seen it – but measles is a very serious illness. Generally an acute disease of children, measles is spread by the measles virus where it infects the body via the respiratory route and establishes a systemic [...]... Read more »

The Lone Wolf or the Support Group Enthusiast?

by Lorimer Moseley in BodyInMind

What type of person are you?? When tough times come around – whether it is stress at work, a painful injury, or forced participation in Secret Santa – what do you do? Some people, those lone wolf types, find relief in being alone, taking some time to regroup, and dealing with the problem themselves. Others, [...]... Read more »

Can a Font Make You Smarter?

by Kari Kenefick in Promega Connections

Today is the second Monday of the New Year, January 10, 2011 and we are returning to work, school and normal life, you know, the one without endless shopping, cooking and preparing. Hopefully most of your holiday 2010 remembrances are fond ones…the greetings, baked goods, travel, gifts…all good. Hold on. The greetings; was there was [...]... Read more »

Crowdsourcing Science with TOPSAN

by Sanford- Burnham in Beaker

New advances in technology are allowing scientists to sequence genomes and determine the structures of the proteins they encode at a faster rate and lower cost than ever before. The NIH’s Protein Structure Initiative centers, such as the Joint Center for Structural Genomics (JCSG), have been instrumental in establishing the structures of hundreds of proteins [...]...

Supermassive Black Hole Surprise?
CREDIT: Reines, et al., David Nidever, NRAO/AUI/NSF, NASA
The dwarf galaxy Henize 2-10, seen in visible light by the Hubble Space Telescope. The central, light-pink region shows an area of radio emission, seen with the Very Large Array. This area indicates the presence of a supermassive black hole drawing in material from its surroundings. This also is indicated by strong X-ray emission from this region detected by the Chandra X-Ray........ Read more »

Count Your Plaintiffs Before Certification Hatches: Class Size Matters in Some Unexpected Ways

by Dr. Ken Broda-Bahm in Persuasive Litigator

By: Dr. Ken Broda-Bahm - When dealing with the number of plaintiffs in a class action, mass tort, or other large scale litigation, is "Super-Size Me" the plaintiff's best choice? At a legal level, the U.S. Supreme Court will get a chance to weigh in, after the decision last week to determine whether as many as 1.5 million female Wal-Mart workers claiming gender discrimination can be certified as a class (Dukes v. Wal-Mart). The common belief is that a large number of plaintiffs serves to maximiz........ Read more »

Barnacle Evolution I: Phylogeny Served Without Plates

by Kevin Zelnio in Deep Sea News

Lepas anatifera from Washington state, USA. Photo credit: David Cowles 1997.
Barnacle evolution was recently rewritten by a large effort of Perez-Losada and colleagues in 2008. Using a combination of genes and morphological traits they rejected some of the ideas that were foundational to barnacle biology and taxonomy, while giving new support for other ideas.

Endless Forms Most Viral

by Moselio Schaechter in Small Things Considered

by Welkin E. Johnson

Perhaps more than any other biological discipline, the study of animal viruses is confined to the present. Virions are simply not the stuff of which robust fossils are made. Phylogenetic analysis can help by revealing deep relationships between extant viral lineages, yet such reconstructions lack detail (telling us nothing about transitional or extinct viral forms, the movement of viruses between species, or the timing of major events in viral evolution), and molecular cloc........

Care and equality in volunteer tourism: the perspective of locals

by Émilie Crossley in Journeys through the psychosocial

Advocates of volunteer tourism are keen to stress that the relationship between hosts and guests it engenders is one of responsibility, equality and reciprocity. It is a model of tourism that supposedly brings benefits to all parties involved, especially to host communities in developing countries, and which stands in firm opposition to the insensitive and [...]...

Learning the passive

by gameswithwords in Games with Words

If Microsoft Word had its way, passive verbs would be excised from the language. That would solve children some problems, because passive verbs are more difficult to learn than one might think, because not all verbs passivize. Consider:

*The bicycle was resembled by John.
*Three bicycles are had by John.
*Many people are escaped by the argument.

The bicycle was resembled by John: A how-to guide.
So children must learn which verbs have passives and which don't. I recently sat down to read........ Read more »

The Source of Levodopa’s Unwanted Dance

by Rob Mitchum in ScienceLife

The motor symptoms of Parkinson’s disease - tremor, inability to initiate movement, rigidity - result from the loss of neurons that secrete the neurotransmitter dopamine. It therefore follows that the best way to treat these symptoms is by replacing a person’s lost dopamine, the strategy behind the drug levodopa. For the first few years, levodopa [...]... Read more »

Managing Supply Chains with multiple Pipelines

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Companies offer a smaller or larger range of products serving different markets, depending on their history and primarily the respective business model.

From a supply chain management point of view this poses the question if it is ok just to use the same supply chain strategy for all those products.

Pipelines vs. Supply Chains
Aitken et al. (2005) make a convincing argument against this approach and instead suggest the "pipeline" to describe the specific operational mechanisms and procedu........ Read more »

Velociraptor Table Scraps

by Brian Switek in Dinosaur Tracking

What did Velociraptor eat? Despite what the Jurassic Park franchise might suggest, the answer is not “tourists and hapless scientists.” Those were in rather short supply during the Mesozoic. Instead, as reported in Palaeogeography, Palaeoclimatology, Palaeoecology last year, recently found fossils confirm that this famous, sickle-clawed dinosaur fed upon the horned dinosaur Protoceratops. In 1971, [...]... Read more »

Lemur Week: Ringtailed Lemurs Look Where You're Looking

by Jason Goldman in The Thoughtful Animal

In honor of Science Online, which begins on Thursday night, I will be writing about lemurs this week. Why lemurs? Because on Friday morning, as a part of Science Online, I will be taking a tour of the Duke Lemur Center.

It is common among animals - especially primates - to orient their gaze preferentially towards other individuals, as well as to follow the gaze of others. Lots of attention has been paid to gaze-following, in part because the ability to recognize and orient to the behavior of ot........ Read more »

Delusions, odd and common: Living in the prodrome, part 2
