Why your proteome is not acting its age

by avi_wener in The European Biotechnologist

In an article published “”in press” this week in Molecular & Cellular Proteomics (MCP), scientists from the Department of Proteomics and Signal Transduction at the Max-Planck Institute of Biochemistry in Germany report that accurate quantification of more than 4,000 mouse tissue proteins reveals minimal proteome changes during aging. The authors Dirk Walther and Matthias Mann [...]... Read more »

Life in the dark

by gregdowney in Neuroanthropology

My wife, along with her many other jobs – paid and unpaid – is the local director of a campus exchange program that brings US students to Wollongong, New South Wales.  Because of her background in outdoor education and adventure therapy, she does a great job taking visiting Yanks on weekend activities that get the students to see a side of life in Australia that they might not otherwise see.  From Mystery Bay on the South Coast, to Mount Guluga with an Aboriginal guide, to abseiling (rapel........

Just got vaccinated... again

by Daniel in Ego sum Daniel

I chose to get vaccinated for the seasonal flu this year as well! This is my post from last year. I think it's a good idea to get vaccinated, even if you're young and healthy. If nothing else, I'm making it a yearly statement in the face of the anti-vaccination loonies. Last year I got vaccinated for both the seasonal flu and the H1N1 or "swine" flu. Understandably last year's relative hysteria about swine flu is nowhere to be seen this year. But whatever happened after that? Wonder no more, the........ Read more »

Boys Equal to Girls in Math Performance

by Ultimo167 in Strong Silent Types

A big meta-analysis by Lindberg et al. (2010) tells the truth yet again: given the right conditions, boys and girls perform equally well in math. What the authors (2010) wonder, and I do too, is how come such stridently sexist stereotypes persist about the capabilities of females to do math, when in fact there is no substance whatsoever to promulgate or sustain such stereotypes? Liberating news for women who like to count and for men, who like me, love poetry…... Read more »

Can Sea Snakes Predict The Future? What About Hurricanes? Lottery Numbers?

by Dr. M in Deep Sea News

Undoubtedly you have heard that dogs can sense earthquakes before the tremors occur. While anecdotes are common, experimental evidence supporting these claims remains elusive. The USGS in the 1970′s even examined the ability of animal prediction “but nothing concrete came out of [these experiments]“.
Cueing on changes in the weather is frequent among the animal kindgom.  Indeed, . . . → Read More: Can Sea Snakes Predict The Future? What About Hurricanes? Lottery Num........ Read more »

Autism and Genetics: It's Complicated

Saturday Review: Vaccines and the Immune System

by Kevin Bonham in Food Matters

I have a love/hate relationship with Nature Reviews: Immunology. It comes out once per month, and is usually packed with easy to read articles about fascinating (to me) topics, and each is filled with tons of great references so I can dig into the issue more. On the one hand, I get really excited about all the great things to read and new ways to expand my knowledge. On the other hand - that's a lot of reading. My Instapaper queue is about 80% Nature Reviews (15% other papers, and 5% random crap........ Read more »

Tracking Ecstasy Abuse with Google Trends

by William Yates, M.D. in Brain Posts

I’ve been interested in the possibility of using Google Trends to monitor patterns of drug abuse in the U.S. and throughout the world.  My hypothesis is that drug abuse patterns will be reflected by the number and geographic distribution of Google searches for a drug key word. Google Trends monitors the number of search engine key words.  Countries and cities are ranked based on the relative number of searches.  If a country or city has more than their expected number of searche........

Crabs and Cancer

by Journal Watch Online in Journal Watch Online

It’s an argument oft heard in conservation circles: Endangered ecosystems are chock full of chemical compounds that could be the next big blockbuster drug — but these life-saving compounds are lost every time a species goes extinct. Estimating the financial value of biodiversity, however, has been a complicated calculation. Now, researchers have put a number […] Read More »... Read more »

As one of the oldest cities in the world, Rome has seen its fair share of drama, from the fall of Julius Caesar to the rise of facism. Now comes another sad tale: a study documenting the loss of Rome’s insect inhabitants over the last century. The innovative research could help conservationists focus insect protection […] Read More »... Read more »

Daytime Napping Improves Memory

by Shaheen Lakhan in Brain Blogger

Napping sounds like just the thing for babies and elderly, but even healthy adults can rely on a daytime snooze to improve memory. A recent study suggests that napping not only strengthens memory but also reorganizes memory and links information together to form memory networks for an easy retrieval later.... Read more »

The bacteria in your belly Pt.1 - Babies

Initially the baby’s immune system has to cope with a form of microbial exposure while still inside the womb which will determine how it will cope with microbes after birth. Whilst incubating the baby the mother will be interacting with her environment, including the microbes within it, and these interactions put indirect pressure on the growing baby too.... Read more »

Why Genes Aren't Enough to Create a Personality

by David Berreby in Mind Matters


Psychiatrists see a lot of people who are, to use the technical term, screwed up. Psychiatrists' talk, then, often turns around curing, or ameliorating, or at least preventing "bad" behaviors and feelings—drug addiction, violence, learning disabilities, crippling anxieties and the like. And a number of psychiatrists sounded that note at the University of Massachusetts conference on behavioral epigenetics last weekend. But throughout the proceedings, there was an undertow pullin........ Read more »
