ResearchBlogCast #11: Using the genome to identify species
by Dave Munger in ResearchBlogging.org News
How do you define a species? Most people would probably say species are similar organisms that can reproduce sexually to produce viable offspring. But what about organisms that don’t reproduce sexually? Surely they have species too.
Today we’re discussing new research suggesting a different way to define species, using their genomes. It’s an intriguing study that [...]... Read more »

ResearchBlogCast #10: Does being a little crazy make you more creative?
by Dave Munger in ResearchBlogging.org News
Throughout history we’ve seen examples of artists and others who, while possessing amazing talent, also don’t seem “normal.” Whether it be tormented artists like Vincent van Gogh, or the stereotype of the “mad scientist,” it often seems like a little schizophrenia might underlie amazing genius.
In fact, some psychological studies have found that schizophrenics do tend [...]... Read more »

ResearchBlogCast #9: Genetics, fertility, and disease
by Dave Munger in ResearchBlogging.org News
Why would a deadly genetically-transmitted disease persist? Doesn’t “survival of the fittest” mean that any genetic mutation that causes premature death should quickly be extinguished? In the case of Cystic Fibrosis, the problem is even more dramatic, because CF causes infertility in men. How could this gene possibly survive? Yet it not only survives, it [...]... Read more »

ResearchBlogCast #8: Protecting the Environment While Reducing Poverty
by Dave Munger in ResearchBlogging.org News
Some of the most bio-diverse areas of the world are also some of the most impoverished, which is why it can seem cruel to create national parks and other protected areas to preserve these ecosystems. Aren’t the human lives in those regions more important than plants or other animals? Some research has supported the idea [...]... Read more »

ResearchBlogCast #7: Why would we ever cooperate?
by Dave Munger in ResearchBlogging.org News
Cooperation is seen not only in humans, but in societies formed by organisms from ants to baboons. But in many cases, it’s difficult to figure out why any individual would want to cooperate. Wouldn’t it be easier just to take what you want without doing any work? While cooperation is good for the group, why [...]... Read more »

ResearchBlogCast #6: Emotional Intelligence and Bullying, In Person and Online
by Dave Munger in ResearchBlogging.org News
Cyber-bullying is a growing problem, but it’s so new that there’s not much research about it. So Krystal D’Costa begins her work studying cyber-bullying by considering what goes into real-world bullying.
Each week, Kevin Zelnio, Razib Khan, and I choose one or more journal articles to discuss in podcast form. This week, while Kevin is on [...]... Read more »

ResearchBlogCast #5: A mathematical model for ecological impact
by Dave Munger in ResearchBlogging.org News
There’s no denying that global warming will impose massive changes on the environment. But a recent paper suggests that the models ecologists typically use to assess the effects of environmental changes may be neglecting a key factor: The ability of organisms to adapt to the environment. What are the implications of incorporating the capacity for [...]... Read more »

ResearchBlogCast #4: Fewer big fish in the sea
by Dave Munger in ResearchBlogging.org News
As more and more commercial fishers compete for fewer and fewer fish, ecologists are beginning to explore the impact. What happens when all or most of the big fish are caught? Does the rest of the ecosystem somehow compensate?
As we do each week, Kevin Zelnio, Razib Khan, and I have chosen a journal article to [...]... Read more »

ResearchBlogging.org and PLoS work together to measure the impact of journal articles
by Dave Munger in ResearchBlogging.org News
With over 800,000 journal articles published in 2008 alone, it’s impossible even for experts to read all the peer-reviewed research published in their fields. So how do they choose which articles to read? How do non-experts decide which articles are the most important? Until recently, there really wasn’t an effective way to assess the importance [...]...

Where will science blogging go from here?
by Dave Munger in ResearchBlogging.org News
ResearchBlogging.orgIn 2007, Bora Zivkovic estimated the number of science blogs at 1,000 - 1,200. Now, over a year later, I suspect that figure is outdated. We have over 450 blogs registered for ResearchBlogging.org, but only half of the blogs at scienceblogs.com are registered. Nature Network, with its hundred or so blogs, is not represented at all because their blogging software isn't compatible with our system. Scientific Blogging, larger than the Nature Network, barely has a presence h........ Read more »
