Cells that vomit fungus and other issues of science papers

by Lorax in Angry by Choice

This weeks journal club was on Cryptococcus neoformans and an odd way it may get of out macrophage some of the time, at least in vitro, maybe. The paper in question is: 

The Human Fungal Pathogen Cryptococcus neoformans Escapes Macrophages by a Phagosome Emptying Mechanism That Is Inhibited by Arp2/3 Complex-Mediated Actin Polymerisation by Simon A. Johnston, Robin C. May. PLoS Pathogens 6(8) e1001041.

This work follows up a really cool observation published by t........ Read more »

Better Chemistry Through Breeding

by Matthew DiLeo in The Scientist Gardener

I recently had the opportunity to visit the fabled heart of the USDA-ARS empire: Beltsville.

I heard all about the tornado that knocked down all the campus trees, smashed in the greenhouses and threw doors down hallways a few years ago, visited their food sensory lab (a controlled environment where fruit samples are passed through a wall to waiting taste testers), and saw greenhouses packed full of cacao (where research on one of my favorite fungi, Crinipellis perniciosa, is co-f........

Why Justin Timberlake Should Avoid Transitive Verbs

by Livia Blackburne in A Brain Scientist's Take on Writing

As writers, we're always trying to find words that perfectly capture our meaning.  "I broke the cookie jar" has a different feel than "The cookie jar broke." But does it really matter? Would the average reader really notice the difference? A recent study suggests that subtle wording changes can have real psychological effects.

Psychologist from Stanford University were interested in the distinction between agentive (a.k.a. transitive) or nonagentive (a.k.a. nontransitive) verbs. For exampl........ Read more »

Components of Early Outpatient Palliative Care Consultation for Patients with NSCLC

by Lyle Fettig, MD in Pallimed: a Hospice & Palliative Medicine Blog

Vancouver 2011
We don't usually comment on stuff from the main palliative care journals, but the Journal of Palliative Medicine published a study that supplements the NEJM trial on early palliative care in metastatic non-small lung cancer.  (See our initial reactions to the NEJM study here, here, and here.)  The present study examines the content and length of time spent during the initial outpatient consultation that took place during the trial. 

In the study, palliativ........ Read more »

Gut Flora, Probiotics and Vitamins A D – Do they influence Allergy and Autoimmunity

by Michael Ash in Nutri-Link Ltd - Clinical Education

The fields of immunology, microbiology, nutrition, epigenetics and metabolism are rapidly converging utilising a systems biology methodology to explain our intimate relationships with our microbial cohabitants. For over 30 years data has been building to scientifically support the hypothesis that intestinal cohabitants operate in a collective manner with macro and micro food intakes to shape and define our immune systems from an early age. The result is a collective impact bound by mutual cooper........ Read more »

Farmland’s impact on tropical forests in the 1980s and 1990s

by Paul Spraycar in Agriculture & Land Use Forum

Recent news about deforestation in the Amazon has been pretty positive: Deforestation has stabilized since the turn of the century, and Brazil, it seems, is on track to meet its stated goals for reducing deforestation and associated greenhouse gas emissions.
Still, the long-term story is one of significant deforestation, primarily to make room for agriculture. Whether agricultural and biofuels expansion dramatically affects the carbon and biodiversity of the world’s forests will largely d........ Read more »

Virophage, the virus eater

by Vincent Racaniello in virology blog

A second virophage has been identified. The name does not signify a virus that infects another virus – it means virus eater. The story of virophages begins with the giant mimivirus, originally isolated from a cooling tower in the United Kingdom. It is the largest known virus, with a capsid 750 nanometers in diameter and [...]... Read more »

Religion and conflict: cause or coincidence?

by Tom Rees in Epiphenom

Conflicts often fracture along religious lines - the Balkans, Israel/Palestine, Northern Ireland to name just a few of the best known. But it's hard to say that religion is the cause of the problem. There are always other factors, like ethnic differences, disputes over land rights and

So what's going on here? Is religion really the cause of conflict, or is it just an innocent bystander?

My partner and I are opposites. Now what?

by eHarmony Labs in eHarmony Labs Blog

All couples struggle with incompatibilities within their relationship. But for some, the tension is acute and the arguments exhausting and repetitive. How can couples best deal with their differences without losing hope about the future of their relationship? Focusing on changing the problem usually results in defensiveness and only short-term changes. Practicing acceptance may be the key to see couples back to calm connection.... Read more »

Emotional Processing Bias in Depression

by William Yates, M.D. in Brain Posts

Clinicians and individuals with depression understand the tendency for depression to be associated with over-interpretation of negative cues in the environment.  Depression seems to heighten perception of negative environmental cues including interpersonal (or social) cues.   The cognitive behavioral model of depression emphasizes the cognitive triad—a negative bias (view) of the self, the environment and the future.Functional magnetic resonance imaging is providing a model to s........

On the origins of smallpox - where and when did variola virus emerge?

2011 may be the year where the last known officially acknowledged stocks of the deadly smallpox virus, variola are destroyed - a virus that claimed over 500 million lives in the 20th century alone. The extensive collection of 'live' virus and DNA stocks totalling over 500 isolates/strains, which are held between the US Centres for Disease Control and the Russian State Research Centre of Virology and Biotechnology may be ordered to be eliminated following World Health Organisation (WHO) recommend........
