Globular Clusters and Voids

by Christine Corbett Moran in Cosmic Rays

In the morning when I get into lab, around 10 in the morning, I have a set routine. Make a cup of coffee or tea, update my research wiki with a new entry corresponding to the day’s tasks, write/reply to work related emails, admin (spam management etc.), scan/vote on papers of interest. Finally I [...]... Read more »

Other people may experience more misery than you realise

by BPS Research Digest in BPS Research Digest

You are not alone ...
Have you ever had the feeling that everyone else seems so sorted, so at ease? You look about you and see friends chatting over lunch, people laughing on their mobiles, others escaping contentedly through novels or newspapers. According to Alexander Jordan and colleagues, most of us have such a tendency to underestimate other people's experience of negative emotion. In turn the researchers think this skewed perception perpetuates a collective delusion in which we all striv........ Read more »

The genomic heritage of French Canadians

by Razib Khan in Gene Expression

Image Credit: Anirudh Koul
One of the great things about the mass personal genomic revolution is that it allows people to have direct access to their own information. This is important for the more than 90% of the human population which has sketchy genealogical records. But even with genealogical records there are often omissions and biases in transmission of information. This is one reason that HAP, Dodecad, and Eurogenes BGA are so interesting: they combine what people already know with scien........ Read more »

Imitation and Social Cognition in Humans and Chimpanzees (II): Rational Imitation in Human Infants and Human-Raised Chimps

by Michael in A Replicated Typo 2.0


In my last post I wrote about two experiments on imitation in young children and chimpanzees by Lyons et al. (2005) and Horner & Whiten (2005).  Their results suggested that young children tend to copy both the ‘necessary’ and the ‘unnecessary’ parts of a demonstrator’s action wh0 shows them how to get a reward out . . . → Read More: Imitation and Social Cognition in Humans and Chimpanzees (II): Rational Imitation in Human Infant........

Why Teenagers don’t use Social Networking Sites

by Dr Shock in Dr Shock MD PhD

In a recent study the conclusion about social networking sites and teens was that 93% of teens and young adults go online, compared to only 38% of adults over 65 years of age. It is surprising that 7% of 12-29 year olds still don’t use social networking sites. Twitter is the exception because it’s the [...]

Tipping Points and the Precautionary Principle

by Noam Ross in Noam Ross

Image source: FlickrMany ecological systems have tipping points - thresholds where small changes in impacts can have very large effects on on ecosystem functioning, often in a bad way.  Lakes, for example, might show little impact from nutrient pollution until a threshold level is reached, and then massive algal blooms form that choke off many other species growth.
In the absence of knowledge of exactly how far one can push a system before reaching a tipping point, many invoke the precautio........ Read more »

Preventing Shingles

by Debajyoti Datta in Medicine...Life

Shingles, also known as Herpes Zoster, usually occurs in elderly adults. It is characterized by painful eruption of vesicular lesions that follow a dermatomal distribution. The thoracic and lumbar roots are most commonly affected.
Pain precedes the appearance of the lesions and is severe and debilitating. The incidence and severity of herpes zoster increases with increasing age... Read more »

Gurgling or Death Rattle? Does it predict pneumonia?

by Christian Sinclair, MD in Pallimed: a Hospice & Palliative Medicine Blog

The physical exam is an important skill for the practitioner of palliative medical arts because we may be working with patients in their home where technical diagnostic options are limited or in a treatment mode that has been defined by avoiding further diagnostic tests.  So I am particularly interested by any article that discusses clinical examination skills relevant to palliative medicine.  Of course the title did not hurt in causing me to pause.  "Gurgling ........

Holy Wars in Holy Lands

In the year AD 1098 a spruce tree was chopped down in the Chuska Mountains, which run roughly along what is now the border between Arizona and New Mexico.  We don’t know who cut it down, exactly, since the people living in the area at the time had no system of writing and have therefore [...]...

the bottom line on hypothermia

by Michael Lombardi in a New Life in the Sea

This 2010/2011 winter has been brutally cold here in the Northeast, and unarguably colder than most. As time has passed over the years, it's become harder and harder to jump in the water this time of year. But, therein lies no choice if one is to continue working as a diving contractor in New England. There is nothing pleasant about it, and all you can do is plan well in advance for the elements.

For the majority of the winter months, say late November through early March, we use hotwater suits........ Read more »

An evolutionary explanation of consumption

by Jason Collins in Evolving Economics

Since Thorstein Veblen’s 1899 book Theory of the Leisure Class, the economics profession has taken a somewhat mixed approach to consumption. In areas such signalling theory, Veblen’s argument that conspicuous consumption must be wasteful and expensive to be a reliable signal of wealth is well recognised. Conspicuous consumption has a purpose as a signal. However, [...]... Read more »

Psychology’s Frenemies
