What Do We Really Know About Utahraptor?

by Brian Switek in Dinosaur Tracking

When it was released in 1993, Jurassic Park turned Velociraptor into a household name. Agile and cunning, it was a type of predatory dinosaur theater audiences hadn’t seen before. But paleontologists knew the movie’s raptors were drawn with a bit of artistic license. For one thing, the dinosaurs had actually been based on the sickle-clawed [...]... Read more »

Might Pleistocene Fido Have Been A Fox?

by Jason Goldman in The Thoughtful Animal

There is a small bit of land, only about a square kilometer, that has added a new wrinkle to the story of animal domestication. This bit of land located in Northern Jordan, just southeast of the Sea of Galilee near the banks of the Jordan River, is home to an archaeological site known as 'Uyun al-Hammam. One key feature of this site, excavated in 2005, is a burial ground containing the remains of at least eleven humans in eight different gravesites. The early humans were buried here sometime dur........ Read more »

One of these mutualists is not like the other

by Jeremy Yoder in Denim and Tweed

Over the last few months I've been writing a lot about how different species interactions have different evolutionary effects. The studies I've looked at so far focus on effects over just a few generations—barely time to take notice, in evolutionary time. The February issue of The American Naturalist remedies this short-term perspective with a paper showing that over millions of years, two different kinds of mutualists had very different effects on the history of one group of orchids [$a].

Trade and natural selection

by Jason Collins in Evolving Economics

Economic theory tells us that trade makes the parties involved better off. Through trade, a person can specialise in the activity in which they have a comparative advantage. A person is better off even if they are trading with someone who is better than them at all activities. This is because the less productive person [...]... Read more »

Is Exercise More About “Calories In” Than “Calories Out”?

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Most people believe that it is somehow possible to create a sustainable caloric deficit by burning calories through exercise.
This is why treadmills and exercise bikes display calories and many folks obsess about burning those “extra calories” (often only to eat or drink them right back).
Although exercise is certainly not the panacea for weight loss, there [...]... Read more »

Prehospital Intravenous Fluid Administration is Associated With Higher Mortality in Trauma Patients – Part II

by Rogue Medic in Rogue Medic

Even the "no fluids group" in that study did have "two 14 gauge IVs started." If we evaluated that study according to the criteria of the current study, both groups received IV fluids, since both had IVs started.

We know that is not true.

In the Bickell study, we know which of the patients who had IVs started received fluids and we know how much fluid patients received.... Read more »

Stroke cures man of life-long stammer

by BPS Research Digest in BPS Research Digest

The cerebellum is coloured green in this model
Thanks to the success of the Kings Speech movie, most of us are familiar with the 'developmental' kind of stammering that begins in childhood. However, more rarely, stammering can also have a sudden onset, triggered by illness or injury to the brain. Far rarer still are cases where a person with a pre-existing, developmental stammer suffers from brain injury or disease and is subsequently cured. In fact, a team led by Magid Bakheit at Mosley Hall ........ Read more »

Purists and players

by David Winter in Careers - in Theory

Is four too much for you? Last week I presented a few career-style typologies that came in sets of four, but it’s entirely possible that remembering four types might be too much for you — it often is for me. So, how about just two types: Players and Purists. These two archetypes represent extreme approaches [...]... Read more »

The evolution of man is no cartoon

by Razib Khan in Gene Expression

I was semi-offline for much of last week, so I only randomly heard from someone about the “Science paper” on which Molly Przeworski is an author. Finally having a chance to read it front to back it seems rather a complement to other papers, addressed to both man and beast. The major “value add” seems to be the extra juice they squeezed out of the data because they looked at the full genomes, instead of just genotypes. As I occasionally note the chips are marvels of techn........ Read more »

Who are more likely to experience flow?

by Dr Shock in Dr Shock MD PhD

I’ve written before about flow as part of creativity while improvising with Jazz. Flow can be defined as: the holistic sensation that people feel when they act with total concentration and intrinsic enjoyment. But who experiences flow more easily, what character traits are related to the likelihood of experiencing flow?
The researchers used the temperament [...]

Taro: Past and Future

by Matthew DiLeo in The Scientist Gardener

I just discovered the local international supermarket (which is awesome by the way). It's filled with exotic fruits and vegetables, assorted sea creatures in boxes of ice and freezers full of animal pieces usually reserved for industrial uses.

I didn't find any dragonfruit (which I've been wanting to try), but they had cherimoyas, jackfruit, different cacti pieces, sugarcane, cassava, weird bananas, all kinds of odd leafy vegetables and squash-like things that were a couple feet across! Faced w........ Read more »

Sex, Science, and Social Policy

by Stephanie Zvan in Almost Diamonds

When it comes to the politicization of scientific topics and science denialism, everyone knows about the forces opposing our understanding evolution and global warming. Would it surprise you to see similar tactics on display when the subject is sex?In the well-known cases, political actors band together with researchers who continually produce results favoring the politicos pet topics. It's not that hard to produce the desired results, even when the mass of evidence doesn't support your side. I........ Read more »

Are new neurons really more excitable? (yes)

by Jason Snyder in Functional Neurogenesis

Some facts on neuronal excitability:

Excitable: the ability to fire action potentials.
More excitable: fires action potentials, but more.
More LTP: not the same as more excitable.
Less inhibition: also not the same as more excitable, though the two may go hand in hand.
The Scholarpedia page on neuronal excitability, which was last modified on 13 August 2009, has been [...]... Read more »
