A spot of Cold

by Rita in we are all in the gutter

I read 3 papers! Three beautiful, science-packed, revolutionary and mind-blowing papers! Ok, maybe not – but trust me, after being so busy with things like measuring redshifts, fixing codes and mountains of admin/conference organising, almost any science is pure beauty for the old brain.

But one of these papers did tap into something I’m quite interested in, and it’s related to the Cosmic Microwave Background (CMB)....... Read more »

The Revealed Slow Aging Hypothesis

by Reason in Fight Aging!

I noticed an interesting idea in the form of a published research paper today. To what degree might we attribute the accelerating rise in human life span in recent centuries to an increased survival rate for people who bear gene variants that (a) harm the prospects for survival to adulthood in low-technology settings, but (b) lead to a longer life expectancy for those who do survive? Healthy life span is rapidly increasing and human aging seems to be postponed. ... To explain current increase in........ Read more »

The Bible Says: Nobody Loves Gays

by Ultimo167 in Strong Silent Types

Barton (2010) covers familiar territory, in showing up that life for GLBTI people in the Bible Belt in the US is harsh. However, the liberationist methodology she employed in her research gives a fresh, insightful and deeply personal view of what it means to be hated for being who you are. ... Read more »

Palaeontologists uncover new Pachycephalosaurian dinosaur

A new species of plant-eating dinosaur, which sports a grapefruit sized mass of bone on the top of its skull, has been uncovered in Texas’ Big Bend National Park. The find, which would have lived 70 to 80 million years ago, is reported in the latest issue of Cretaceous Research.... Read more »

Helping kids eat better by changing school lunches (Part 1)

by Dave in The Daily Monthly

Last year a study was released suggesting that kids who bought lunch at school tended to eat less healthy foods than kids who brought their own lunch from home. Since the National School Lunch Program in the US is supposed to encourage children to eat better, this was quite a blow. If kids don’t eat [...]... Read more »

The ethical dilemma for doctors in religious hospitals

by Tom Rees in Epiphenom

One in every eight hospitals in the USA is a religious foundation. As with faith schools in the UK, they receive government funding (in the form of Medicare and Medicaid payments, as well as tax-exempt bonds), but they're allowed to set their own policies to conform with their religious principles.So, for example, some religious hospitals stop their doctors from providing legal medical treatment, such as contraception, abortion, and certain end-of-life treatment options.This poses a potential di........

Set-shifting as a Biomarker for Eating Disorders

by William Yates, M.D. in Brain Posts

Significant research focuses on the identification of biomarkers in a a variety of psychiatric disorders. A biomarker can be any biological variable that is associated with an illness. Biomarkers are important because they provide an opportunity to identify high-risk individuals prior to disease onset. Early intervention in these individuals may reduce the risk of illness or reduce the severity and impairment of the disorder. Biomarkers may also be valuable in identifying genes associated wi........ Read more »

Of Yeast and Men

by Neuroskeptic in Neuroskeptic

Nature reports on the Dissection of genetically complex traits with extremely large pools of yeast segregants.Ehrenreich et al have a new way of mapping the genetic basis of complex traits in yeast, "complex" being what geneticists call anything which isn't controlled by one single gene. They dub their approach "Extreme QTL mapping". This suggests images of geneticists running experiments atop Everest, or perhaps collecting blood samples from lions with their bare hands, but actuallyExtreme QTL ........ Read more »

Why Don’t We Just Eat Better?

by Christie Wilcox in Nutrition Wonderland

Why is it so hard for us to eat a healthy diet? It would appear to be the easiest solution in the world. Just choose wisely at the grocery store and - Poof! - you can feel better, lose weight, and look fantastic. Of course, we all know that eating healthy is never as easy as it sounds. So what is in the way of making good food choices?... Read more »

Ankle Sprains: Tape, Bracing - doesn't matter finds research - but how'd we get so busted up in the first place?

by mc in begin to dig (b2d)

A recent paper has presented the results of a bunch of trials looking at interventions for ankle sprains. Main result? if someone's had an ankle injury - like a sprain - then tape or brace doesn't seem to show a difference: both seem to cut down reinjury. What's troublesome on a metalevel, is first how sort of accepted the notion of this level of injury seems to be, and second how nascent in the approach described here is the model that for folks who haven't been injured - as a preventitive - th........

New Study: Some Sciences Really Are Better Than Others

by David Berreby in Mind Matters

If you want to rile up a biologist and have no pointed stick handy, try this: Tell her that chemistry or physics are "harder," more fundamentally "sciencey" sciences than hers. "You can't use the standards of one science to judge another," she might say. "Physics is different from biology, not better." Not so, you answer: There must be standards common to all the sciences, which some meet better than others do. You're now set up for a seemingly........ Read more »

Hawaiian Submarine Canyons: Biodiversity Hotspots

by Christie Wilcox in Observations of a Nerd

When we think about the vast diversity of life in the ocean, we automatically picture pristine coral reefs teeming with life. This is especially true for rich, tropical locations like Hawaii. What we don't think of are the deep, dark depths of the canyons that lie just beyond the shallow paradises we know and love. Scientists have known for years that these deep water locations may contain a wide variety of species, but don't talk about them as much because no one had ever explored them to see w........

Bodily motions influence memory and emotions

by Mo in Neurophilosophy

WHEN talking about our feelings, we often use expressions that link emotions with movements or positions in space. If, for example, one receives good news, they might say that their "spirit soared", or that they are feeling "on top of the world". Conversely, negative emotions are associated with downward movements and positions - somebody who is sad is often said to be "down in the dumps", or feeling "low".

According to a new study published in this month's issue the journal Cognition, expressi........ Read more »

Relieve Pain with Spiritual Images

It seems my Catholic mother may have been onto something when she said religion helps with pain. According to an Oxford study, invoking one’s religious beliefs for pain relief has some scientific backing.
Researchers at The Oxford Center for Science of the Mind gave atheists and Roman Catholics electric shocks while they looked at two paintings, [...]... Read more »

The sharp shooters of marine life

by Katie Kline in EcoTone

The archerfish’s long distance spitting can fire a bug off of a branch and send it down to the water’s surface, and the nearly-blind pistol shrimp uses its gigantic claw to stun its prey with a bubble nearly as hot as the Sun. However, if the archerfish didn’t have keen eyes enabling it to detect an insect against a vegetative background, and if the pistol shrimp lacked its protective eye covers, called orbital hoods, these animals might never have developed the ballistic mechanisms that ........

Mate Selection at Frog Cocktail Parties: Keep it Short, Low, Loud, and Stand Out from the Crowd (Oh, and have a colorful vocal sac, too)

When I lived in Sioux City, IA, I had the opportunity of hanging out with a zoologist who studied the Plains Spadefoot Toad (Spea bombifrons). I would go out with her on nighttime listening surveys, and we would slowly drive the gravel farm roads in the middle of nowhere, weaving from one side to [...]... Read more »

Tip of the Week: MEME Suite of Motif Discovery Tools

by Jennifer in OpenHelix

In this week’s tip I’m going to introduce you to a suite of motif discovery tools, and show you (briefly) how to use one of the tools. The MEME suite is a comprehensive collection of tools for analysis of both protein and DNA motifs. As described on the MEME Suite homepage, or in the citation that I reference below, this set of tools allows one to use as much or as little of the suite as meets their research needs. A user can initially find motifs with either the MEME or GLAM2 algor........ Read more »
