Quorum Sensing in Bacteria: How a Picture can be Worth a Thousand Words

by Promega Corporation in Promega Connections

Increasingly, multimedia and video are being used in addition to traditional delivery methods to communicate scientific findings. Journals such as PLoS ONE, Cell, Nature and others often use video to either showcase particular articles, or offer authors the opportunity to include multimedia elements as part of their article. Some subjects lend themselves better to video [...]... Read more »

Koch’s postulates in the 21st century

by Vincent Racaniello in virology blog

For thousands of years, epidemics of contagious diseases were believed to be caused by the wrath of the gods, configuration of stars, or miasma. The association of specific microorganisms with disease came about as a consequence of the work of the German physician Robert Koch. He formulated a set of criteria that could be used [...]...

the bizarre oceans of the outer solar system

by Greg Fish in weird things

The outer solar system is a strange place. It’s a realm of frozen gas giants surrounded by icy moons and yet, it’s actually home to one of the most promising destinations for alien hunters in the solar system, offering an even more convincing argument for an alien biosphere than Mars to some. We’re talking about [...]... Read more »

A flood of DRiPs

by iayork in Mystery Rays from Outer Space







“Untitled (Green Silver)” – Jackson Pollock



In the past few weeks not only did I post a short update on the DRiPs hypothesis here, but coincidentally a bunch of papers on DRiPs have also been published. I’ll probably cover some of these in more detail at some point, but here are some of the recent papers [...]... Read more »

Early risers are more proactive than evening people

by BPS Research Digest in BPS Research Digest

I've always envied early risers, those who spring out of bed at the crack of dawn, ready, it seems, to take on the world. Of course their early vitality could be short-lived. Morning friskiness gives the impression of a positive nature but are 'larks' really more proactive people than 'owls'?Yes, according to Christoph Randler who surveyed 367 student participants and found a correlation between their self-reported 'morningness' (as revealed by their answers to questions about how easy they find........

Reflections after Science Online 2010 (#Scio10)

by Christie Wilcox in Observations of a Nerd

I'm writing this while on the plane, flying back from a fantastic weekend in North Carolina. Before I can even begin reflecting on the past few days, I have to thank NESCent again for their generous travel grant which allowed me to go to Science Online in the first place. Without their funding, I'd have spent the weekend laying out on a beach instead of freezing my butt off with over 200 amazing people who, thought diverse in many ways, all have one thing in common: a passion for science communi........

Those naughty plants!

by Anastasia Bodnar in Biofortified

Many people, including me, are concerned about potential harm to crop biodiversity from gene flow. Most people’s concern focuses on transgenics. There is a certain probability, albeit small, that transgenes will end up in the progeny of non-transgenic plants, weedy relatives of the crop, or wild relatives that grow nearby due to pollen flow. Transgenes can also be moved from place to place by accidental or purposeful movement of seeds. How much transgene flow is actually happening is a sub........ Read more »

Friday Weird Science: Duck, duck, penis.

by Evil Monkey in Neurotopia

Sci is going to so some selfish Friday Weird Science today. Selfish, because this article isn't new, and was reported on by one of the GREATS. This guy. He (of course) did a completely brilliant job, and when he talked about it at SciOnline this past weekend, Sci was compelled to go and see the material for herself. And it's something to SEE. And so see it you shall.

The reason this is selfish is because Sci knows it's been reported on before. She wants to do it her ownself, as an excuse ........ Read more »

Nothing wrong with synthetic biology, It's just B-I-O-L-O-G-Y and the rest is silence

by Abhishek Tiwari in Fisheye Perspective

Recent issue of Nature magazine has few very interesting articles about synthetic biology and one of them is "Five hard truths for synthetic biology" written by Roberta Kwok. When I first read this article my first reaction was- nothing wrong with synthetic biology, it's just biology gets in the way of the engineering.Nothing to do with their heartsNothing to do with their headsNothing to do with their homesNothing to do with their bedsIt's just B-I-O-L-O-G-YCan't you seeIt's just BiologyBiology........

A plethora of MRSA sequences

by Keith Robison in Omics! Omics!

The Sanger Institute's paper in Science describing the sequencing of multiple MRSA (methicillin-resistant Staphylococcus aureus) genomes is very nifty and demonstrates a whole new potential market for next-generation sequencing: the tracking of infections in support of better control measures.MRSA is a serious health issue; a friend of mine's relative is battling it right now. MRSA is commonly acquired in health care facilities. Further spread can be combated by rigorous attention to disinfect........ Read more »

The Evolution of Iron-Clad Samurai Snails With Gold Feet

by Dr. M in Deep Sea News

It is told in the Hagakure: The Book of the Samurai
At the time of the attack on the castle at Shimabara, Tazaki Geki was wearing very resplendent armor.  Lord Katsuhige was not pleased by this, and after that every time he saw something showy he would say, “That’s just like Geki’s armor.” In the light [...]... Read more »

Social networking for taxonomists

by Iddo Friedberg in Byte Size Biology

Also, there are still quite a few people who want to document, describe and make the rest of us aware of the magnitude and diversity of [...]... Read more »

Actually, maybe economists did prove money can buy happiness…

by Michael Slezak in Good, Bad, and Bogus

A little while ago, I wrote a post about an article in Science about the relationship between “objective” measurements of “quality of life” and subjective measurements of “life-satisfaction”. The article found a very high correlation between these measurements leading the authors to claim that there was now “objective verification” of the subjective measurements often used [...]...

Spine Immobilization in Penetrating Trauma: More Harm Than Good?

by Rogue Medic in Rogue Medic

Also posted over at Paramedicine 101. Go check out the rest of what is there.A recent study points out some of the problems with EMS (Emergency Medical Services) treatment in some places. Each medical director, or state medical director, is permitted to ignore the evidence that some treatments are harmful. They can use ignorance as an excuse for continuing harmful practices. Rather than ignorance, those familiar with the research will claim that somebody might benefit. Their battle cry is What i........ Read more »
