Omics approach shows fewer changes from GE than breeding and environment

by David Tribe in Biofortified

From GMO Pundit. Ricroch AE, Bergé JB, & Kuntz M (2011). Evaluation of genetically engineered crops using transcriptomic, proteomic and metabolomic profiling techniques. Plant physiology PMID: 21350035 The authors conducted a literature survey on 44 recent “omic” comparisons between GE and non-GE crop lines. Those profiling techniques (transcriptomics, proteomics, and metabolomics) have been increasingly applied to the analysis of genetically engineered (GE) crop plants with regard to t........

Got beef with worms?

by zacharoo in Lawn Chair Anthropology

Photo: {http://news.brown.edu/pressreleases/2009/09/bilateral}, by Eric Rottinger at kahikai.orgFlipping through the current issue of Current Biology, it sounds like someone has some serious beef with acoelomorph flatworms. Apparently these critters have been used as a model for the 'missing link' between simple-bodied cnidarians (like jellyfish) and bilaterians (bilaterally symmetrical animals like you and me and flies and fish, and really a good deal of animal biodiversity); and this may be pr........

Social ties and recovery go together like ham and eggs

by PeaPod in Binge Inking

The homeless face particular challenges on the road to recovery. This US research sought to answer how social ties influence the decision to enter and continue with treatment for substance use disorders in a sample of homeless men. Could what the researchers found be applied in treatment settings in the UK?... Read more »

Exploring Phobias in the Brain. An Introduction.

by neurobites in Neurobites

My fellow neuro-enthusiasts! I have a special post for you this time☺. We have received a special request to explore the issue of phobias. In the interest of turning the world into neurogeeks we must deliver. That and we are suckers for a pretty face. Have you or a “friend” let out a childish, high-pitched [...]... Read more »

arxiv stuffs a wormhole with perfect fluids

by Greg Fish in weird things

Some bloggers just can’t resist going back to the same rich source of things just begging to be really torn into and dissected, and I’m no exception. After growling about the papers being posted and promoted on arXiv, I still find myself going through some of the more bizarre and out of left field proposals [...]... Read more »

Deprived, Deranged and Disrupted

by perishedcore in Changing Heart and Mind

Research about sleep inevitably leads to circadian rhythms and CLOCK genes. One group of researchers goes farther and suggests that 24 hour exposure to light beyond that produced by the denizens of space and the moon and demands which interfere or replace traditional sleep wake cycles may be doing damage beyond imagination. Circadian (daily) rhythms [...]... Read more »

Patients, pathogens, ecosystems

“A terrified man realizing he has just contracted the plague, surrounded by a group of people.” By E.M. Ward, 1848. Even the most lethal pathogens we know of don’t kill every single infected individual.1. Sometimes this is because the pathogen that infects the person is relatively weak. Sometimes it’s because the dose was low. And [...]... Read more »

Best Acknowledgment Ever

by teofilo in Gambler's House

In 1978 H. Martin Wobst of the University of Massachusetts at Amherst published a short article in American Antiquity entitled “The Archaeo-Ethnology of Hunter-Gatherers or the Tyranny of the Ethnographic Record in Archaeology.”  Despite the evocative title, the article itself is a highly theoretical argument about the proper relationship between archaeology and ethnography that is [...]...

Genomic Imprinting VI: Hemimethylation

by Jon Wilkins in Lost in Transcription

So, last time, we discussed the fact that the expression differences associated with genomic imprinting rely on the existence of epigenetic differences, such as DNA methylation. We also mentioned that those differences are established separately in the male and female germ lines. That is, one methylation pattern is established in the female germ line during oogenesis (egg formation), while a different pattern is established in the male germ line during spermatogenesis (sperm formation).

It is s........ Read more »

Lunar cycles and reproduction in the deep sea

by Uncharted Atolls in Uncharted Atolls

Some biological patterns in marine species, particularly concerning reproduction, are related to the moon.  Shallow-ocean corals, for example, undergo mass spawning events (the synchronous release of eggs and sperm into the water column to combine), the timing of which, are set to the lunar clock.  Reef fishes, shallow-ocean echinoderms, mollusks and more, also time spawning [...]...

The biochemistry of religious aggression

by Tom Rees in Epiphenom

Anyone who's taken a passing interest in the news at any time in the past 100 years will have noticed that Israel/Palestine region has had more than its fair share of religious violence. So it's the ideal place to start looking if you want to investigatge the links between religiously-motivated aggression and the common-or-garden variety.

Peer Effects in Education

by Michael Bishop in Permutations

Who would deny that friends, especially those in the same classroom, influence how much each other learn.  This seems like a really important process to understand.  It’s one of my research interests.  Unfortunately it’s really hard! Mark, over at Observational Epidemiology, links us to VOXEU for a paper attempting to shed light on the topic. [...]... Read more »

Imitation and Social Cognition (III): Man’s best friend

by Michael in A Replicated Typo 2.0


Tweet


In my two previous posts (here and here) about imitation and social cognition I wrote about experiments which showed that

1)  young children tend to imitate both the necessary as well as the unnecessary actions when shown how to get at a reward, whereas wild chimpanzees only imitate the necessary actions.

And that

2) both 14-month old human infants . . . → Read More: Imitation and Social Cognition (III): Man’s best friend... Read more »

Is the yellowstone caldera safe?

by Greg Laden in Greg Laden's Blog

Not long after Yellowstone Park was officially created, a small group of campers were killed by Nez Pers Indians on the run from US troops1. More recently, the last time I was in the area, a ranger was killed by a Grizzly Bear (so was his horse) on the edge of the park. A quick glance at my sister's newspaper archives (Lightning Fingers Liz a.k.a. Caldera Girl has been running newspapers in the region for nearly forty years) shows a distinctive pattern of danger in the Caldera, mainly in relat........ Read more »

Fusion for the Future: NIF

by The Astronomist in The Astronomist.

Fusion is only 50 years away and it will solve all of the worlds energy problems. That is the good news. The bad news is that it has been 50 years away for the last 50 years. If that situation is maddening to you then you are not alone. Leonardo Mascheroni, a retired Los Alamos National Laboratory physicist, wanted funding to build a colossal laser for producing energy from fusion and was willing to trade the United States' nuclear weapons secrets to realize his dream. Mascheroni was recently in........ Read more »
