I admit my confirmation bias has exercise being a very minor contributor to a person's overall weight - at least in terms of a direct effect.There's no doubt that exercise plays a major role in weight management, but I feel that it's primary role is to support a healthy living attitude. Anyone who's ever trained hard for anything knows it's a great deal easier to think about healthy eating and healthy habits when you actually feel health than when you don't, and exercise certainly confers a sen........

Sci was a little startled recently when she saw "the latest study" on ADHD splashed across the frontpage of Yahoo. You can see it here on Reuters.
PESTICIDES TIED TO ADHD.
(Run for the hills, indeed. Or maybe run AWAY from the hills, since they might have pesticides)
However, the story broke a good TWO DAYS in advance of the paper actually coming out, and so Sci was forced to possess her soul in patience until she had access.
But she's got it now! And let's take a look at this thing.

It’s not every day you read about suggestions for potential health-related travel advisories to U.S. states.

Turtles are often a draw in coastal tourism destinations. As popularity grows, though, pressure to develop more tourist accommodations creates a conflict with the need to protect the turtles’ sensitive beach habitats.A recent paper in Conservation and Society – ‘Tourists and turtles: Searching for a balance in Tortuguero, Costa Rica’ – examines several aspects of ecotourism in Tortuguero, Costa Rica. The results raise some interesting questions about balancing the trade-offs between ac........ Read more »

Imagine an episode of CSI-Silurian. The team of detective-scientists are investigating a case of wholescale graffiti in the middle Silurian, and they’re looking for fingerprints. Someone – or something – has taken a knife to the land and carved out a network of rivers and streams.

There's been a debate for some time as to whether or not "fasted cardio" is ok. There's a "fasted cardio roundtable" at t-nation discussing this, and good arguments on either side.

The Yellowstone caldera is home to thousands of geothermal springs and 75% of the world's geysers, with kilometers-deep groundwater flow systems that tap magmatic heat sources. As that hot groundwater rises toward the surface, it interacts with shallower, cooler groundwater to produce multi-phase mixing, boiling, and a huge array of different hydrothermal features. While the deep, geothermal water is sexy and merits both the tourist and scientific attention given to it, there's a largely untold ........ Read more »

A fear for many women is that as we age, we seem to be more vulnerable to the "Help Help, i've fallen and i can't get up" hip fracture and related. Awhile ago, i wrote about bone building, and what's known about strategies to keep it together and enhance it. Quick review: bone builds in response to demand.

The Indonesian Financial Crisis of 1998 was disastrous for the families caught up in it. The rupiah devalued by 80%, and food prices more than doubled. Worst affected was the price of rice, which rose by 280%.
As a result, the monthly surplus that the average family had to spend on non-food items dropped by two-thirds - from $7.34 to $2.64.
In the period spanning the crisis, the Indonesian Central Statistics Office ran a series of surveys - the Hundred Villages Survey - which followed over 100........ Read more »

Chondrocladia turbiformis, a ruthless carnivore hauled from bottom of the sea off new New Zealand by NIWA scientists, has been named among the top ten new species described last year. This abyssal predator isn't a kraken, a plesiosaur that time forgot or even an improbable (but awesome) hybrid. It's a sponge.
It may come as some surprise that a sponge can be a carnivore, or even that sponges are animals. Sedentary as they are, sponges tick all the boxes for inclusion in the kingdom Anamalia. T........ Read more »

The oil spill in the Gulf of Mexico is now over a month in duration and continues to worsen. Estimates of the total oil flowing from the damaged were estimated initially at 5,000 barrels per day.

I covered babirusas recently; you might have noticed. As you'll know if you read those articles, Meijaard & Groves (2002a, b) argued a few years ago that Babyrousa babyrussa of tradition should actually be split up into several phylogenetic species. Coincidentally, I published an article on lumping vs splitting in extant mega-mammals only a few weeks before Groves et al. (2010) split white rhinos into two phylogenetic species.
