gregladen | May 13, 2015Josh Harkinson at Mother Jones recently posted an item called "Scores of Scientists Raise Alarm About the Long-Term Health Effects of Cellphones." I like Josh's work, but there are some problems with this article I want to point out, some of which parallel problems in the more general discussion of cell phone safety.
Before looking at the Mother Jones piece, here's the bottom line: There is no known mechanism by which cell phone use can lead to cancer (usually, brain cancer is of concern). There have been many studies on this and related issues. They vary in quality and in what they look…

If there is anything that the past few decades of research and study of major global challenges tells us, it is that truly effective solutions to sustainability challenges require truly integrated approaches across disciplines, fields of study, data sets, and institutions. We are not going to solve 21st century global problems with 20th century tools.
The planet is faced with a wide range of regional and global threats: air and water pollution, loss of biodiversity, a rapidly changing climate and new risks from extreme weather events, energy and food security, conflicts over resources such…
gregladen | October 16, 2014Given the current and developing situation in Dallas, where two health workers have become infected with Ebola while caring for a patient, it is reasonable to ask if health workers might decide to call in sick for a few months until this whole highly infectious often fatal disease thing blows over. Daniel Barnett, of the Department of Environmental Health Sciences at the Johns Hopkins Bloomberg School of Public Health, has looked into health workers’ unwillingness to report to work when there is a potential for infectious-disease transmission to themselves and their family members.

gregladen | September 10, 2014The news is bleak. I don't have a lot of confidence in the reported numbers. At one time it was said that on a nice Saturday in the summer, four out of five cars driving around in downtown Boston were looking for a parking place. This is somewhat like the situation in Liberia and possibly other affected areas. There may be as many Ebola victims driving around in taxis looking for a clinic as there are in clinics. Or maybe a fewer. Or, maybe more. Maybe a lot more.
But, we have to work with the data we have. There are two charts based on the information provided by WHO for up through…
gregladen | September 8, 2014This is the time of year parents start scanning their facebook feeds and other sources of information for what to expect our children to get sick with, how badly, and when. For a couple of years in a row, a few years ago, we were getting hit with a norovirus, causing diarrhea, vomiting, and a lot of lost daycare or school days. This year we are seeing reports of an outbreak of the scary-sounding "Enterovirus EV-D68." Hundreds of kids are sick enough to get treatment in several states, currently Colorado, Iowa, Missouri, Kansas, Oklahoma, Illinois, Ohio, North Carolina, Georgia and Kentucky…

The list is long, and the path there is uncertain. Yet if we look back and how much better our lives are today than they were hundreds or (especially) thousands of years ago, it's clear that we owe an awful lot to science and…
gregladen | August 25, 2014The number of people known or suspected to be infected with Ebola in the West African outbreak is increasing, and the rate at which it is increasing is increasing. About 40 new cases are being reported per day on average, but the number of new cases has been going up by a few a day.
However, it is still unclear that these numbers represent what is actually happening on the ground. There is little confidence that the WHO has a good idea of who is currently stricken with the disease, and efforts to contain those who are have had mixed results.
A second outbreak is now occurring in the DR…
gregladen | August 2, 2014LATEST UPDATE HERE
It is true that this particular outbreak of Ebola has taken health officials somewhat by surprise. It is impossible to know, but I suspect that if you had asked a few ebola experts, a year ago, if there could be an epidemic that would spread across three or four countries, infect a couple thousand people, and last with no sign of letting up for a few months (that is the current situation, more or less), most would say no, probably not, though it is within the range of possibilities. Does the fact (assuming it is true) that this particular Ebola outbreak is unprecedented…
gregladen | May 7, 2014I'm thinking it will be the food you eat that gets you. Here's why.
Humans eat a wide variety of foods; as a species, the diversity of species we eat is greater than any other animal by a very large margin, with the only quirky exception being the animals that we take along with us, the commensals such as rats and cockroaches. Most primates eat a high diversity of foods, but about two million years ago or a bit less, according to the “Cooking Hypothesis” (which a lot of people think is correct) we took an already diverse primate diet and added to it anything we might encounter in the…
dr. dolittle | April 27, 2014Another exciting day at the Experimental Biology meeting for physiologists! Although I am a bit nervous about the session on the negative effects of sleep deprivation, "Sleepless in San Diego: Is Sleep Deprivation the New Silent Killer?" Hmmm, maybe I should have gone to bed a bit earlier last night...
Dr. Karen Matthews (Univ of Pittsburgh) has studied the effects of sleep deprivation in teens from low-income families found that less than 6 hours of sleep per night can negatively impact mood, academic achievement and health.
Another talk that I found interesting was on how sleep deprivation…
gregladen | April 6, 2014I just watched a report on ABC news about anti-vaxers causing the current and alarming measles outbreak. It was a reasonable report for MSM though I missed large parts of it because I was multitasking ineffectively. But an idea came to me that would go a long way to manage this problem of anti-vaxers threatening everyone else's health and well being. Lives, even. They are threatening our lives.
Here's the deal. Most public schools have a mealy-mouthed policy that allows people to send their kids to school unvaccinated because they are dumb asses. That's a problem and that should be…
gregladen | March 15, 2014Sounds like kind of a technical question.
In Irritable Bowl Disease, including Crohn's Disease, it may be the case that bad bacteria cause intestinal wall inflammation. Or, inflammation could allow bad bacteria to do better than good bacteria. And, that might be an oversimplification because there could be other factors as well, including genetic predispositions.
Many younger people who present with various abdominal symptoms are treated with antibiotics. These antibiotics could disproportionately favor bad bacteria.
Whether from inflammation, genes, or use of antibiotics, it does…
gregladen | July 30, 2013... which would be really funny because ... well, you clearly see why this is funny.
Christian groups and sects are often opposed to the use of biological tissue that would otherwise be discarded in research and therapy including "stem cell research." This is because they think some of that biological tissue could be future parishioners, or because they watched too many Disney movies involving fairies. Or something. Anyway, there is this one kind of stem cell that exists among regular cells that can be extracted from the body of a living, breathing already signed up parishioners and the…

There's a lot to enjoy when it's warm and tropical, which it is many places this time of year. The flowers are out, the Sun often shines, and there's no shortage of spectacular music. Have a listen to to West Virginia-based band The Recipe, as they rock out (and give a shout-out to Neil Armstrong's moonwalk) in their great song,
Whiskey Pickle.
But there's an unwelcome visitor that comes along with this kind of weather: the mosquito.

gregladen | July 21, 2013It seems to me that the science of epidemiology is a lot like being in shoe sales in a country on the pacific rim. You never know when the other shoe is going to drop, but you know it will. Our species (humans) is numerous, contiguous, and dense (in more ways than one). This means that a highly virulent pathogen could spread across the globe and kill a gazillion people before we could do anything to stop it. Yet, such a thing has not happened in modern times, meaning, since the widespread and easy flux of population provided by the airline industry at several scales of space.
At the…

One of the most difficult things to talk about, for any self-respecting scientist, is politics. Like all of you, I have my preferences, my opinions, and my vision for what a better world would look like. I'm also well aware that if I talked about all of them, there probably wouldn't be a single one of you out there who agreed with everything I had to say.

The Comparative and Evolutionary Physiology section held their Scholander Poster competition for young comparative physiologists today! It was exciting to see all of the students present their work.
Here are some of the highlights:
Raffaele Pilla, Dominic P, D'Agostino, Carol S. Landon, and Jay B. Dean from Molecular Pharmacology and Physiology, University of South Florida, Tampa, FL. These researchers demonstrated that a ketone body, often thought of as waste products resulting from the use of fats for energy, can have protective effects against seizures caused by exposure to hyperbaric…
aardvarchaeology | April 21, 2013As part of my duties as chairman of the Swedish Skeptics, earlier tonight I took part in a studio discussion on Swedish TV4 about Gardasil, the vaccine against human papilloma virus that is offered to all 12-y-o Swedish girls. It was a pretty silly affair. The TV people had decided on the angle that the information given about the vaccine to young girls isn't detailed enough. For instance, the school hallway fliers don't tell the kids that the protection rate against HPV isn't 100% (duh) or that very rarely the vaccine can provoke some serious side effects (duh again). These are traits, I…
