Ionic Liquid Resistance Mechanism to Advance Biofuel Production

by dailyfusion in The Daily Fusion

Researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI), a multi-institutional partnership led by Berkeley Lab, have identified the genetic origins of a microbial resistance to ionic liquids and successfully introduced this ionic liquid resistance into a strain of E. coli bacteria for the production of advanced biofuels....

Climate sensitivity wrangles don’t change the big picture on emissions

by Andy Extance in Simple Climate

Modelling studies from Joeri Rogelj at the Swiss Federal Institute of Technology, ETH Zurich show we still need to release fewer greenhouse gases even if the world does warm more slowly in response to them than today’s best estimates suggest. ... Read more »

Inflaming inflammation and psychiatry

by Paul Whiteley in Questioning Answers

The systematic review published by Mitchell & Goldstein [1] kinda says it all when it comes to our current view of the topic of inflammation and psychiatry, and in particular inflammation and neuropsychiatric conditions such as autism, schizophrenia and attention deficit hyperactivity disorder (ADHD): "There is preliminary evidence for elevated markers of inflammation in this population".All at sea (JMW Turner) @ Wikipedia I've talked quite a bit on this blog about how, a........

Problem solving Goldfinches

by Africa Gomez in BugBlog

I realised only recently that Goldfinch manipulation abilities are superb. They hold large seeds with one foot while manoeuvring them into position to feed, or fold stems back to hold berries or seeds securely, or hand upside down to reach the thinnest branches. Yesterday I watched a small flock feeding on the catkins of a silver birch. The closest bird to me held a catkin while feeding from it and even changed the foot it used to hold it. It happens that Goldfinch manipulation abilities ha........ Read more »

Why mixing languages isn’t so bad after all

by Ray Carey in ELFA project

by Kaisa Pietikäinen You know those moments when you’re speaking English (as a lingua franca, or ELF), and all of a sudden your mind goes blank? You know the word you’re looking for, but you just can’t get it into your head. You might remember it in another language, but your brain just isn’t connecting […]... Read more »

Manipulating the mouse penis bone, with science

by Brooke LaFlamme in Molecular Love (and other facts of life)

he girth of a mouse penis bone depends on the stiffness of the competition. That’s what Leigh Simmons and Renée Firman at the University of Western Australia found after several generations of experimental evolution in mice. Over the course of the experiment, male mice developed thicker penis bones (or bacula, if you want to be scientific about it) when females were allowed to mate with multiple males. The study was published in the January issue of the journal Evolution.... Read more »

Parenthood, Trial or Tribulation? Part 2

by Psych Your Mind in Psych Your Mind

On New Year’s Day I became a parent, sparking my curiosity in the research on parenting and well-being and inspiring a four-part series on parenthood and happiness. This is the second post. Check out the first post here.Are parents happier than non-parents? Researchers have generally set about trying to answer this deceptively simple question in three ways:Are people with children happier than those without children?This is the most common approach to research on parenthood and well-being.

Wellbeing is shaped by your day's little highlights, not merely its mishaps

by Alex Fradera in BPS Occupational Digest

Wellbeing research has tended to model work-life as a default state punctuated by negative events such as conflicts, mistakes, or unwelcome change. In this way, it follows the broader model of psychological health research that focuses on harmful interruption to normal functioning , a model that Martin Seligman and Mihaly Csikszentmihalyi were contesting in 2000 when they launched the Positive Psychology movement. In a new paper, Joyce Bono and colleagues further this tradition by drawing attent........ Read more »

Highly unusual proteinaceous infectious agents probed by hydrogen/deuterium exchange

by Clay Clark in Biochem Blogs

  Prion proteins are implicated in a perplexing class of infectious diseases called transmissible spongiform encephalopathies (TSEs). Prion proteins are ubiquitous among mammals with roughly 90% sequence identity across species. TSEs include Creutzfeldt-Jakob disease in humans and bovine spongiform encephalopathy in cattle, AKA mad cow disease.  The disease ontology involves the conversion of the cellular […]... Read more »

Scientists Convince People Their Hands Are Rocks

by Elizabeth Preston in Inkfish

No matter how much of a critical thinker you consider yourself, your brain is pretty gullible. With a few minutes and a couple of props, your brain can be convinced that one of your limbs is made of rubber or invisible, or that your whole body is the size of a Barbie doll’s. All these illusions […]The post Scientists Convince People Their Hands Are Rocks appeared first on Inkfish....

FLCN may act as a molecular switch

Chromosome translocations involving the transcription factor TFE3, leading to its overexpression, cause roughly 15% of renal cell carcinomas in patients under 45 years of age (Kuroda et al., 2012). TFE3 is constitutively activated in FLCN-null cells (Hong et al., 2010), … Continue reading →... Read more »

'Mini heart' organ may help return venous blood

by beredim in Stem Cells Freak

George Washington University (GW) researcher Narine Sarvazyan, Ph.D., has invented a new organ to help return blood flow from veins lacking functional valves. A rhythmically contracting cuff made of cardiac muscle cells surrounds the vein acting as a 'mini heart' to aid blood flow through venous segments. The cuff can be made using cardiomyocytes derived from the patient's own adult stem cells, eliminating the chance of implant rejection."We are suggesting, for the first time, t........ Read more »

Simple Jury Persuasion: “It makes no difference to me but I’m sure it would to a lot of other people.”

by Rita Handrich in The Jury Room

The study of bias fascinates us. We can easily spot prejudice in others but are oblivious to our own biases. We often ask a question at the end of a research project about community values and whether our (uniformly unbiased and considerate) mock jurors think others in the area would be biased against a party […]
