Feeling Energetic

by Journal Watch Online in Journal Watch Online

Crashing surf and surging currents make for dramatic seaside scenery. These high-energy environments are also increasingly eyed for producing electricity, however – and that trend highlights the need for more study of the ecological implications of ocean energy projects, argues a new study.
Engineers have come up with a variety of promising ways to turn […] Read More »... Read more »

Antibodies neutralize viral infectivity inside cells

by Vincent Racaniello in virology blog

Antibodies are an important component of the host defense against viral infection. These molecules, produced 7-14 days after infection, neutralize viral infectivity, thereby limiting the spread of infection. Antibodies are thought to neutralize viral infectivity in several ways: by forming noninfectious aggregates that cannot enter cells, or by blocking virion attachment to cells or uncoating [...]...

Hitching a Ride on a Trilobite

by Laelaps in Laelaps

Fossil skeletons are static things. They no longer grow or respond to the stresses and strains of life. Tucked away on shelves or propped up on intricate armatures, fossil bones and other mineralized hard parts show us the shape of ancient organisms, but we can only perceive whispers of the lives those remains represent.
The way [...]... Read more »

Perfluorinated chemical exposure from food wrappers

by Ashartus in exposure/effect

Perfluorinated chemicals, which are organic molecules with several fluoride atoms attached to the carbon chain, have had a fair amount of attention from environmental scientists over the past several years, primarily due to their long persistence in the environment. They’ve been used in a large number of consumer products – probably best known for non-stick [...]... Read more »

Unexpected Horned Dinosaur Reveals Complex Evolutionary Pattern

by Brian Switek in Dinosaur Tracking

In many of the books about dinosaurs I read as a child, the evolution of horned dinosaurs (ceratopsians) looked pretty straightforward. Early, lanky forms such as Psittacosaurus were succeeded by a miniature precursor of later types—Protoceratops—before generating the array of large, spiky ceratopsid dinosaurs such as Triceratops and Styracosaurus. Yet, as more discoveries have been [...]... Read more »

Social skills training for children with autism: not all group therapies are created equal

by Nestor Lopez-Duran PhD in Child-Psych

Last week, while discussing a study that compared medication and psychotherapy for the treatment of teen depression, I mentioned how the current research suggests that the efficacy of Cognitive Behavioral Therapy (CBT) as treatment for depression in adolescents may vary significantly as a function of small variations between the different versions of CBT used by clinicians.

New Possibilities for Depression: A MAP Kinase regulator

by Scicurious in Neurotic Physiology

One of the problems with depression as a disorder is that the symptoms never seem to manifest the same. To give you an idea of what I’m talking about, here are some of the DSM IV recognized symptoms of depression: 1) Insomnia or hypersomnia (not sleeping OR sleeping too much) 2) Having no appetite OR [...]...

How Obesity Gets Your GOAT

by Arya M. Sharma in Dr. Sharma's Obesity Notes


As my readers may recall, yesterday, I presented at the at theGlobal Obesity Summit 2010, Jackson, Mississippi.

Coastal northwest American marten conservation

by DeLene Beeland in Wild Muse

Just how many sub-species of American martens are living in California and Oregon? Well, there may be one less than experts thought, according to a 2009 study published in Conservation Genetics. American martens (Martes americana) are slightly larger than a house cat and are carnivorous members of the Mustelid family. They live in boreal forests [...]... Read more »

Expanding retraction

by Zen Faulkes in NeuroDojo

Should a scientific paper be retracted because it is mistaken?

We’re not talking here about misconduct, or deliberate fraud. We’re talking about a result that is, for whatever reason, wrong.

At the Retraction Watch blog, Tom DeCoursey argues that papers that are wrong should be retracted from the scientific record. His main argument is that people waste a lot of time trying to reproduce results that later papers have been unable to confirm.

This may be a rather different view of retractio........ Read more »

November 11, 2010

by Erin Campbell in HighMag Blog

As long there are cells and fascinated scientists, then there will always be unsolved mysteries. A recent paper helps clear up discrepancies in the actin literature, using a combination of killer microscopy and a systematic look at how one protein functions. So many cellular processes depend on a dynamic network of actin filaments, and there is a long list of proteins that associate with and regulate these networks. One of those proteins is called VASP and is found at the leading edge of m........ Read more »

Queen Bees are the consequence not the cause of sexist work-places

by BPS Research Digest in BPS Research Digest

Queen Bee is a term used in business psychology to refer to women in senior positions who boast about their own masculine attributes, whilst derogating their female subordinates and endorsing sexist stereotypes. According to articles in the popular press, the presence of Queen Bees is as much a cause of gender inequality at work as is the sexism shown by men. A new article by Belle Derks and her colleagues challenges this claim, arguing instead that sexist work-places are a breeding gr........ Read more »

Another challenge to confront with geoengineering: Ocean plankton toxins

by Phil Camill in Global Change: Intersection of Nature and Culture


There have been several critiques of geoengineering as a climate mitigation tool.  Two of the most incisive, in my opinion, come from science and ethics.
The first is a 2007 paper in PNAS by Matthews and Caldeira showing that if we establish aerosol clouds or space reflectors while doing nothing to reduce carbon emissions, we run [...]... Read more »

Genetics and Epigenetics of Leukemia

by Daniel Koboldt in Massgenomics

A study online at the New England Journal of Medicine reports that DNMT3A mutations in acute myeloid leukemia are common and associated with poor outcome for intermediate-risk patients. Previously, our group had characterized the genomes of two patients with cytogenetically normal AML (AML1 and AML2). The first genome (AML1) was initially sequenced with Illumina short [...]...

Tetris as a “cognitive vaccine” against traumatic flashbacks?

by Maria P. in noustuff

Everyone is familiar with Tetris. This simple, but addictive game has been studied quite a few times by researchers (see older post). A group from the University of Oxford investigated whether Tetris could be used as a “cognitive vaccine” against flashback development after trauma exposure. Flashbacks are one of the most persistent symptoms of Post Traumatic [...]... Read more »

Alcohol is most harmful but most other illegal drugs are misclassified too.
