Global Warming: Top Scientist Tells Us We have Just One Year Left to Act
Global warming is hitting us already. It is no coincidence that some of the biggest storms and an unexpected number of storms are hitting us now. Nor are food shortages coincidence...nor are they caused primarily by biofuels. Extreme weather, an expected part of global warming, is hitting us hard, damaging crops around the world. Crops are established based on a particular climate. That climate has changed and it will take time for agriculture to adapt and infrastructure to be put into place. Time and money.
Global warming isn't our future. It is our now.

Human Evolution
Recently I wrote a piece kind of throwing together the ideas of human evolution and personal genealogy, two things that clearly are ultimately connected because they both come down to simple genetics and who begat whom, but in reality are so separated in time that we cannot properly connect them. But those who accept genealogies and DNA tests for paternity have to accept evolution, because the concepts are the same. Ultimately genes work a certain way and we understand how they work quite well. Evolution is no great mystery or controversy. What is amazing is that Darwin, with no concept of genes, came up with a system that once genes were studied was found to fit very well how genes actually work. Genetics and Evolution started as separate fields, but amazingly the two separate fields merged almost perfectly. To me genealogy is simply what we can see up close of our evolutionary path. Once we get a few generations back, the branches of our ancestry become quite tangled and hard to see...but they are there. And their imprint is in our genes.

Health Action Alert: Help Keep Antibiotics Effective
An ongoing effort of mine is to fight the misuse of antibiotics. Misuse of antibiotics has been an increasing health hazard for people, leading to many strains of antibiotic resistant bacteria that infect, and sometimes kill, people, particularly children, the elderly and the immunocompromised. Last time I wrote about this I was able to report a victory in the fight to keep antibiotics effective. Today I want to introduce the latest fight.
First, for those who want more background, the Union of Concerned Scientists has an excellent rundown. An excerpt from their site:

Ancestors: Who's your great great great great grandpappy?
Race, ethnicity, culture, family...all important to people. But usually we think of these things completely separate from reality.
I have been reading several books that together have put some of this into perspective. Each of us are part of the whole sweep of human evolution, and we are all related in a very real, genetic way.
This man might be your ancestor:

(Ramesses II, king of Egypt, 13th century BC)
Yep, I bet lots of people today could, if only we had all the information, trace their ancestry back to this man. I would guess somewhere in the millions of people today are his descendants.
Go back far enough and we are all related. This is a fact. Or, more precisely, every little piece of our DNA ultimately derives from a common ancestor that can be traced back to some specific time and place.

Web Seminar: A Target for U.S. Emissions Reductions
Interested in a discussion online about carbon emissions and real, science-based solutions to global warming? This comes from the Union of Concerned Scientists:
A Target for U.S. Emissions Reduction
Join Dr. Brenda Ekwurzel for free web seminar on the analysis for determining “A Target for U.S. Emissions Reductions.†Following a presentation on the findings, will be a Q&A session.
Date: February 20, 2008
Time: 2:00 pm (EST)
Click here to RSVP. Directions on how to join will be emailed to you.
Substantial scientific evidence indicates that an increase in the global average temperature of more than two degrees Celsius (°C) above pre-industrial average (i.e., prior to 1860) poses severe risks to natural systems and human health and well-being. The European Union as well as climate legislation moving through the U.S. Congress both employ 2°C as a guide for policy goals.

Drunken Fruit Flies Get Horney
Drunk males get hornier and hornier the more they drink...to the point they start chasing anything, even other males. Problem is, though they get far more interested in having sex, their performance declines the more they drink.
All of that according to a study from the lab of Kyung-An Han, a neurobiologist at Pennsylvania State University, and reported in Nature News. Oh...the study was done on fruit flies (Drosophila melanogaster).
From the article on Nature News:
In the flies, hypersexuality caused by chronic alcohol exposure has the effect of making the males chase anything with wings — other males included. Although sexual preference in humans is obviously a complex phenomenon not replicated by the fly work, the findings could be used to further establish a fly model system for the study of alcoholism, observers say...
As the concentration of ethanol in the body rises, flies begin to become uncoordinated and oblivious to their surroundings: they get tipsy. “They bump into each other. They bump into the walls,†says Heberlein.

Book Review: Global Warming: The Last Chance for Change
"The last 50 years stick out like a sore thumb... The temperature's gone up and up and up. It bears the imprint of human activity."
--Dr. Michael Oppenheimer, Professor of Geosciences and International Affairs, Princeton University
"It's not something we can adapt to...we can't let it go another 10 years like this."
--Dr. James Hansen, Director NASA Goddard Institute for Space Studies, member National Academy of Sciences
"The weight of evidence for climate change is very strong indeed, and it has gotten stronger over the years...The rate of warming is now greater than it has been for 10,000 years; that means the rate of climate change is greater than it has been for 10,000 years."
--Sir John Houghton, Professor in atmospheric physics, University of Oxford, recipient of Royal Astronomical Society Gold Medal, Honorary Member American Meteorological Society

Short Takes Tuesday
Sparkling Science Writing. Have you been following the recent science reporting by Claudia Dreifus? I have. I first looked at her conversations with scientists out of curiosity and affection – I had met Ms. Dreifus more years ago than I care to repeat, but have remained a reader because she’ll really good at explaining to science idiots like me what those people are doing and talking about. Tuesday’s conversation with DNA sequencer Elizabeth Blackburn is here. But don’t stop there. Her previous profile of yeast researcher Susan Lindquist looks both at women in science and yeast as research targets, but the best is her interview with my favorite sex researcher Pepper Schwartz
Keeping Poor People Down. When it comes to the poor, Mayor Bloomberg’s billionaire instinct for starvation wages and unaffordable housing comes through
