Picking teammates. Original photo by humbert15.When you need partners for some sort of cooperative activity—say, teammates for a game of kickball—you'd probably like to have a choice among several candidates. That lets you weigh considerations about kicking strength and running speed—and who promised to give you h........ Read more »

Update on triple negative breast cancer

by Sally Church in Pharma Strategy Blog

One of the challenges of triple negative breast cancer is that it is defined by what it is not (ie ER/PR-, HER2-), rather than what it is.  This broad subgroup of breast cancer is therefore more heterogeneous in nature than … Continue reading →

Vaginal 'probiotics' may protect against HIV transmission

by Connor Bamford in The Rule of 6ix

According to WHO data, 2009 saw 33.9 million people worldwide infected with the human immunodeficiency virus -  HIV and of these, 1.8 million died from AIDS while 2.9 million were newly infected with the virus. This leaves a year-on-year increase of just over 1 million HIV positive people of which, many of these will go on to pass the virus. Therefore any strategy to eliminate HIV from the human population will have to aim at both treating those already infected as well as preventing new vi........ Read more »

Babies prefer Picasso

by BPS Research Digest in BPS Research Digest

Still life with guitar by Picasso [c.]
Psychologists who study art appreciation have their work cut out. How does one begin to untangle cultural influences from more basic perceptual factors - the cache from the contours? Well one way is to study babies, because they're obviously too young to know about cultural fads and artistic reputations.

Trix Cacchione and her team at the University of Zurich presented nine-month old babies with paintings by the cubist pai........ Read more »

Tuesday Crustie: A fifty year wait for a name

by Zen Faulkes in NeuroDojo

This picture appeared in a wonderful gallery in The Guardian about life on the island of New Guinea a couple of weeks ago.

But in the original paper, you will find another spectacular picture. And before you ask, yes, this is actually the same species:

This second picture is probably more representative of the colouration of the species in the wild. In the paper describing it formally, the authors say its colour is, “Pinkish to orange and sometimes pale yellow.” My understanding is that ........ Read more »

Visual feedback for training novel coordinations

by Andrew Wilson in Notes from Two Scientific Psychologists

The key feature of coordinated rhythmic movements is that not all coordinations are stable. Most other rhythms can be learned, however, which is why we can have jazz drumming. People have been training participants to perform novel coordinations (especially 90°, the least stable rhythm without training) for years now, and have been asking all the standard learning questions - how long does learning take? Does it transfer to other coordinations? The first real studies on learning were by Ke........ Read more »

Learning from Insect Swarms: Smart Cancer Targeting

by Paige Brown in From The Lab Bench

Research published in Nature Materials this month takes lessons from cooperation in nature, including that observed in insect swarms, to create better targeting methods for cancer therapeutics [1]. "Smart" anticancer drug systems can use mechanisms similar to swarm intelligence to locate sites of disease in the human body. ... Read more »

Biofuels and indirect land use change: from hunch to causal connection

by Paul Spraycar in Agriculture & Land Use Forum

In the realm of biofuels and indirect land use change, policy-makers face a dilemma: how to account for a consequence of biomass cultivation that is almost certainly a problem but is very hard to measure. That consequence is indirect land use change, when land biomass production displaces agriculture and other land uses to other places. If those alternative uses shift to land with high carbon stocks, the effect is large greenhouse gas emissions that may wipe out any GHG benefits the biomass prod........ Read more »

Underwear Models and Low Libido

by The Neurocritic in The Neurocritic

Erotic or not? (from Hot Chicks with Douchebags)Hypoactive Sexual Desire Disorder (HSDD) is a controversial diagnosis given to women who have a low (or nonexistent) libido and are distressed about it. The International Definitions Committee (a panel of 13 experts in female sexual dysfunction) from the 2nd International Consultation on Sexual Medicine in Paris defined HSDD, which has also been called Women's Sexual Interest/Desire Disorder (Basson et al., 2004), in the following fashion:There ........

A Walk Along the Paper Trail: Katzogenesis

by Michael Patterson in ...And You Will Know Me By The Trail of Papers

While the last few walks have covered taste receptors, I'm more interested in the central representation of taste.  When you taste something the information is relayed from the taste receptors by three facial nerves to the brainstem (NST), then to the thalamus (VPMpc), and from there to gustatory cortex (GC).  The NST also projects to the amygdala and lateral hypothalamus, sending reward and ...

You’re the Judge: Are You Making Bad Attributions?

by Psych Your Mind in Psych Your Mind

Your romantic partner surprises you with flowers. What are the first thoughts that cross your mind? Do you think “how sweet and thoughtful!” or do your thoughts tend toward the dark side, such as “That’s a look of guilt… what did he do this time?” How we interpret the behaviors of those closes to us says a lot about our relationships. When your spouse arrives home with flower, do you think he’s being sweet or is he guilty of something? If your friend is late for lunch, do you think........ Read more »

Viruses that Infect Parasites that Infect Us: The Matryoshka Dolls of Human Pathogens

by Moselio Schaechter in Small Things Considered

by Jamie Schafer

We’re all too familiar with the viruses that can infect us, from the common cold to yellow fever virus to the endogenous retroviruses that make up a chunk of our genome. Many of us are also acquainted with parasites, such as tape worms or Giardia, that like to set up camp in the human body. But the world of parasites and viruses does not end there. Many parasites or endosymbionts can be infected with viruses. A classic example is Paramecium, which can harbor an endosymbiotic ........ Read more »
