The NYT (Kolata, 2010) recently published a story we'd all like to believe in. After their "lab's usual end-of-the-week beer hour," two Harvard neurology researchers noticed similarities between not only genes associated with both the innate immune system and Alzheimer's disease (AD), but structures, characteristics, and actions of selected proteins as well. Dr. Rudolph E. Tanzi, Dr. Robert D. Moir, and their team found "striking similarities" between the well-known innate immune system protein, LL-37, and amyloid β-protein (Aβ), long considered a waste…

As the year marches forward, ever closer to that summer sun we missed so much during dreary winter days, we also get closer to the traditional summer picnics and barbecues. Sometimes, in our hurry to enjoy quality time with friends and family, we get distracted from our usual practices for proper food handling. We might try to get little Billy his hamburger before he has time for a full-fledged temper tantrum, so we hurry it along, figuring a tiny bit of pink in the middle won't be the end of the world. Or we might realize that we're short a couple of…

As a part of traveling to a developing nation, we are often required to take medical precautions. This generally includes a line-up of shots for various diseases, a few other tests, and various regimens of prophylaxis for possible diseases. I have often left these doctors appointments with a line of band-aids on my arm, a handful of prescriptions and a little weakness in my knees. However, I will readily admit that my malaria prophylaxis is often pushed to the back burner; in fact the last time I went to a developing nation, I didn't even get the malaria…

HIV/AIDS is a major public health problem worldwide. To date, it is estimated that more than 60 million people have been infected with HIV and more than 25 million people have died as a result of HIV/AIDS worldwide1. Despite the high prevalence and mortality rates that are associated with HIV/AIDS, and after more than 29 years of aggressive research efforts, there is still no cure or vaccine to prevent against HIV/AIDS. And although the introduction of antiretroviral (ARV) drugs in the mid 1990s greatly improved the outlook, health and quality of life…
j7uy5 | April 19, 2010Yes, this is old news. I've written about it before, as have
numerous other progressive scientifically-oriented bloggers. But
now that there is an opinion piece featured prominently in the New York
Times, perhaps the issue is gaining momentum.

to protect the health of all Americans. This one wouldn't raise any

Armed with bracing logic, wit and her "public-health nerd" glasses, Elizabeth Pisani reveals the myriad of inconsistencies in today's political systems that prevent our dollars from effectively fighting the spread of HIV. Her research with at-risk populations -- from junkies in prison to sex workers on the street in Cambodia -- demonstrates the sometimes counter-intuitive…

ejohnson | March 22, 2010When we think of our planet's water, we usually think of the vast saltwater oceans that contain 97 percent of it. But the other three percent is equally important to ecosystems and to life as we know it: freshwater found above ground in lakes, rivers, and ponds, and underground in aquifers and streams.
World Water Day was designated by the U.N. General Assembly in 1992 to call attention to issues surrounding freshwater around the globe. This year, with the theme "Clean Water for a Healthy World," World Water Day organizers hope to bring the concepts of wastewater management and water…
mikethemadbiologist | March 18, 2010After finding this post about income inequality and social problems, I decided to check out the 'book version', The Spirit Level: Why More Equal Societies Almost Always do Better, by epidemiologists Richard Wilkinson and Kate Pickett. It has a lot to recommend it (if you want the short pdf version, it's available here). First, the evidence for a correlation across countries and within countries between income inequality and social misery is pretty overwhelming. Second, in the introduction, as opposed to an appendix nobody will read, Wilkinson and Pickett explain the basics of the…
milhayser | March 15, 2010If coming back for seconds is indulgent, then this eighth helping of Pi Day Pies makes us pure hedonists. But hey, the dessert table is the new water cooler.
First, Travis Saunders and his girlfriend cobbled together their own entry on Obesity Panacea, a vegetarian Raspberry Pie that uses agar instead of gelatin. With apple juice, maple syrup, almonds, and oatmeal, this pie looks healthy as well as delicious.
On Adventures in Ethics and Science, Janet Stemwedel offers another vegetarian pie that combines "rich chocolate, tart cherries, and almonds." Mind the parentheses in the Chocolate…
ddobbs | March 11, 2010Helen Branswell, ace flu reporter, delivers the goodsl:
TORONTO A landmark study looking at how to limit the spread of influenza has shown what experts have long believed but hadn't until now proved: Giving flu shots to kids helps protect everyone in a community from the virus.
The study, led by Dr. Mark Loeb of McMaster University in Hamilton, Ont., showed the risk of catching the flu was lowered by nearly 60 per cent in communities where a substantial portion of kids aged three to 15 got flu shots.
That level of indirect protection is nearly as good as what healthy adults might expect…
sastyk | March 2, 2010One of the pleasures of blogging here has been the focus that this community has on issues of public health. Doing everything we can to maintain the health and well-being of populations through a shift into a different model of life is an issue that is deeply important to me - I don't always agree with everyone who writes here on these issues (and, of course, they don't always agree with each other ;-)), but I am struck with admiration of the degree of concern for the public welfare expressed by my Science Blog Colleagues.
Which is why I'm being so presumptuous (since I am a science writer,…

I recently read the book 'Good Germs, Bad Germs' by Jessica Snyder Sachs. I became intrigued by parts of her book that discussed how babies become colonized with bacteria during birth. The most interesting part was the differences between vaginally-delivered and Caesarean-delivered babies. It was not something I had ever thought of before. With my interest piqued, I did a Google scholar search to see what kind of research was being done on this topic. I stumbled upon an article looking at C-sections and risk of childhood allergies, namely asthma. I…

Human papillomaviruses (HPVs) are small DNA viruses that infect epithelial cells. There are well over 100 subtypes of HPV. The subtypes that infect cutaneous epithelia are termed beta-HPVs and those that infect the mucosal epithelia are termed alpha-HPVs. Some alpha-HPVs have received attention as strong risk factors for the development of cervical cancer. Less public awareness has been generated over the role of HPVs in the development of other cancers such as vulvar, vaginal, anal, head and neck, and penile cancers. Only recent research has…

Type I Diabetes Mellitus (T1DM) is a disease most affecting children (previously named juvenile-onset diabetes). However, adults can still develop this life-threatening illness. Research in the genetic arena has provided evidence this disease is partially due to inheritance, leaving a portion of causality yet to be determined. More specifically, a look at certain viruses which attack the beta cells of the pancreas, the cells responsible for producing insulin, have provided new information regarding etiology of T1DM. Some recent research aimed at…

Discussion on consumption of meat products is a common occurrence in my household. Hailing from India, I have always relished meat dishes that my mom cooks up, hot and spicy! However, there is always a nagging guilt on eating animals. People have tried convincing me that we are all part of the food-chain in this ecosystem, so either eat or be eaten. However, in recent times one thought crosses my mind when I stuff that yummy piece of meat in my salivating mouth, will this karma get to me soon? Will my brain dissolve as I chew on the brain of this mute…

The idea of evolutionary medicine is new to me and my understanding is quite shallow but it has piqued my interest. Currently, the book "Why We Get Sick" by Randolph M. Nesse and George C. Williams has been satisfying my curiosity during the 15 minutes of intellectual thought I have left at the end of the day while reading before bed. From what I've read, I'm finding how useful it can be to consider disease in light of evolution and I'm left wondering how I haven't heard of it before. I'm guessing I'm not the only one interested, so let's talk evolutionary…

We've all been there at some point before: a hot summer day, your delicious ice cream cone or tasty treat, and that uneven sidewalk. After taking about ten steps away from the vendor, you mistakenly put your foot into a gigantic fault in the sidewalk and accidentally toss your tasty treat face-down into the pavement. For many of us, "what now?" is actually a deliberation of a bunch of different, yet seemingly important questions: Who is watching me? How hungry am I? How much did it cost? Does this thing look dirty? Can I salvage most of it? But perhaps…
