Common ancestry of life – Q.E.D?

by Tara Cronin in BioMed Central Blog

The proposition that “all the organic beings which have ever lived on this earth descended from some one primordial form”, first put forward by Darwin, and central to modern evolutionary theory, is a commonly held biological view.An attempt by Douglas Theobald, described in a letter to Nature as a ‘formal test’ of the universal common ancestry (UCA) hypothesis, stirred considerable interest recently - whilst the universality of the genetic code and evidence from comparative genomics prov........

Using beauty as an advertising tool - does it always work?

by BPS Research Digest in BPS Research Digest

Announcing that neuroscience writer Jonah Lehrer had been listed as one of Salon's sexiest men of 2010, psychologist and uber-blogger Vaughan Bell joked that an aftershave would soon follow. Vaughan was referring, of course, to the widespread tendency for marketeers to use beautiful people to promote products. The rationale of the tactic is obvious. By pairing a product with an attractive model, hopefully people will come to find the product attractive too. A new study by Debra Trampe and collea........ Read more »

High-Protein-Low-GI Diet Helps Keep Weight Off?

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

Today, the New England Journal of Medicine publishes the results of a large European multicentre trial called the Diet, Obesity, and Genes (DIOGENES) Project, showing that eating slightly more protein and slightly fewer high-glycemic-index foods may make it easier to keep weight off....

Navigating by the (dead) stars

by Niall in we are all in the gutter

Until the last century, astronomy had one very practical purpose, navigation. Ancient mariners used stars such as the North Star and the Southern Cross to work out where in the ocean they were. With the advent of modern methods (the most up to date of which is GPS) navigating by the stars fell by the wayside. Now a new method that combines the ancient idea of stellar aids to navigation with some of the principles of GPS has been suggested to accurately determine the position of spacecraft, and i........

San Antonio Statement on Brominated and Chlorinated Flame Retardants

by Ashartus in exposure/effect

A group of nearly 150 scientists has signed a statement about brominated and chlorinated flame retardants (BFRs and CFRs), essentially asking for some serious thought to be given about whether we really need to be using them the way we are. BFRs and CFRs have been used in a wide range of products due to [...]... Read more »

We were all Africans…before the intermission

by Razib Khan in Gene Expression

Quick review. In the 19th century once the idea that humans were derived from non-human ancestral species was injected into the bloodstream of the intellectual classes there was an immediate debate as to the location of the proto-human homeland; the Urheimat of us all. Charles Darwin favored Africa, but in many ways this ran against the [...]... Read more »

Playing God with Fruity Flies

by Brit Trogen in Science in Seconds

Picture a manly male. He's a little aggressive, the first to initiate courtship. And of course he's got a nice row of sexcombs to go with that black patch on his abdomen.

What female could resist a stud like that?

Courtship in flies involves a series of well-documented behaviors, mostly initiated by the male.... Read more »

Can you name that tune? Song Recognition without Identification

by Psychology 379 bloggers in Cognition & the Arts

Have you ever heard a song on the radio that you recognize but you can’t pinpoint the name of the song? From personal experience, I know this happens to me a lot! I can hear a song on the radio and know I have heard it before but I cannot recall the name the song. It is common for people to recognize a song but how much or how little of the song do you need to hear to recognize it? Do you think you could recognize a song if you just heard a fragment of the song, the rhythm or if you just h........ Read more »

The Social Cognition of Your Thanksgiving Dinner

by Jason Goldman in The Thoughtful Animal

Even still, we tend to think of the turkey as a fairly unintelligent bird, skilled at little more than waddling around, emitting the occasional "gobble," and frying up golden-brown-and-delicious. But...what if I told you that the domestic turkey (Meleagris gallopavo) could actually be quite clever, at least when it comes to social cognition? Apocryphal or not, Ben Franklin may have been on to something with the "Bird of Courage."

Paragliding With Pterodactyls

by Michael Gutbrod in A Scientific Nature

The pterosaurs, or pterodactyls as you might recognize them, flew like no creature has ever flown before.  Leave it to a reptile to do things differently.  While today’s high-fliers have wings with multiple boney “fingers” providing structure, these anomalies of the skies possessed wings with only one long wing finger and a fibrous membrane that [...]...

Light does matter

by Joerg Heber in All That Matters

Light is special. In our everyday experience it behaves like a wave, which gets reflected, refracted and shows interference with other light of the same wavelength. At the same time, light also consists of particles, so-called photons. This duality is quite fundamental: the Hanbury Brown and Twiss experiment for example only works because of the [...]...
