When Tyrannosauraus rex had for breakfast… another Tyrannosaurus rex

by Rogue in Into Oblivion

(This was first published at The Urban Times) In a study published in the online journal PLoS ONE yesterday, researchers show evidence for cannibalistic behaviour in Tyrannosaurus rex. Indeed, the king of the dinosaurs not only fed on other dinos, but also on fellow T. rex, say the researchers after identifying bite marks on giants’ [...]... Read more »

Instant Antidepressants on the Horizon

by Shaheen Lakhan in Brain Blogger

Depression and similar mental disorders like bi-polar disorder, anxiety, and obsessive–compulsive disorder are associated with imbalances in neurotransmitters in the brain. Neurotransmitters are signaling molecules exchanged between neurons (nerve cells) for communication purposes. One of these neurotransmitters is serotonin, and drugs that increase serotonin levels in the brain are the most widely used treatments for [...]... Read more »

The @#$% 2010 Ig Nobel Peace Prize: Pain files 1

by gregdowney in Neuroanthropology

The 2010 Ig Nobel Prizes were awarded recently by the Annals of Improbable Science, and a paper I read a while ago and wanted to comment on won the Ig Nobel for Peace! (By the way, comment on, not because I thought it was Ig Nobel-esque, but because it was actually relevant to my work — what does that say about my research!?)! Congratulations to Richard Stephens, John Atkins, and Andrew Kingston for the prize, awarded for their paper, ‘Swearing as a Response to Pain,’ in Neur........ Read more »

Royce Murray and Caveat Emptor

by egonw in Chem-bla-ics

Derek's blog pointed me to an editorial by Royce Murray Science Blogs and Caveat Emptor (doi:10.1021/ac102628p). He is warning us, science scholars, for blogs. He is accusing bloggers for not being scholarly, not checking facts etc.

He did himself and the journal a big disfavor: in his blog he does precisely what he is accusing the blogger of: fail to check facts. Even worse, particularly for the 'Analytical Chemistry' journal, he showed inadequate in analyzing the problem, putting his scholarl........ Read more »

Saving more than species at Nagoya

by Noam Ross in Noam Ross

There's been a whole lot of interesting stuff coming out this week related the Conference of the Parties (COP 10) for the Convention on Biological Diversity (CBD) going on in Nagoya, Japan right now.   CBD's goal was to slow the loss of biodiversity loss by 2010, but that goal was not achieved, and nations are hammering out how to revive the CBD with new goals for 2020.
At a prepatory meeting in May, governments agreed on 20 more specific draft targets, which aim to be “SMART” -........ Read more »

Why Do Americans Have Yards?

by teofilo in Gambler's House

Today is Blog Action Day, and the topic is water.  I did a post for this last year when the topic was climate change, so I figured I’d do it again.  Water is obviously a huge issue, especially in the arid Southwest, so there are a lot of directions I could go with this.  I [...]... Read more »

Soda, beer, and BPA (and hey, congrats to Canada!)

by Melinda Moyer in Body Politic

Canada deserves a big pat on the back: On Wednesday, our northerly neighbor added bisphenol A (BPA) to its list of known toxic substances. Canada still has to iron out how it will regulate the chemical, but this is definitely a step in the right direction. (Bryan Walsh over at Time just posted a great piece about this, too—among other things he explains why BPA is “a litmus test for environmental health and for risk tolerance.”)
Let me use this news as an excuse to talk some more a........ Read more »

Gliese 581 g: The Goldilocks that isn’t?

by sarah in One Small Step

The discovery of planet Gliese 581 g, an exoplanet just 3 times the mass of our Earth  and located in its host star’s Habitable Zone, was one of the biggest science headlines of the year. The news broke, typically, somewhere between my observing proposal deadline and box number 15: “all the crap that didn’t fit [...]... Read more »

Sleep starved dieters might be thwarting their fat loss plans

by Helen Jaques in In Sickness and In Health

A small study from the United States has suggested that getting too little sleep might prevent dieters from losing as much body fat as they would have had they slept properly. When individuals slept for five and a half hours a night, they lost half as much body fat as when they were allowed to [...]... Read more »

Population trends, not climate, causing increased flood fatalities in Africa

Guest post by Anne Jefferson, assistant professor at the Department of Geography and Earth Sciences, UNC Charlotte, and science blogger at Highly Allochthonous

In August 2009, unusually heavy rains lasting six hours deluged the city of Khartoum in Sudan. Higher, wealthier parts of the city were relatively unaffected, but in the vast shanty towns that surround [...]... Read more »

Breaking The Chain

Could be rough times ahead if you are the big fish atop the food chain in your river. A sophisticated new analysis finds that droughts and floods reshuffle river food webs in dramatically different ways – offering a potential preview of how climate change, dams and other forces may affect top predators such as large […] Read More »...

Blog Action Day 2010 – Water neutrality and its biodiversity benefits

by CJA Bradshaw in ConservationBytes

In my little bid to participate in’s Blog Action Day 2010 – Water, I’ve re-hashed a post from 2008 on ‘water neutrality’. This will also benefit my recently joined readers, and re-invigorate a concept I don’t think has received nearly enough attention globally (or even in parched Australia where I live). So here we [...]... Read more »

Mediterranean Diet Prevents Diabetes - Again

by Steve Parker, M.D. in Advanced Mediterranean Diet

Spanish researchers report that the Mediterranean diet reduced the risk of developing diabetes by 50% in middle-aged and older Spaniards, compared with a low-fat diet. 
Over 400 people participated in a trial comparing two Mediterranean diets and a low-fat diet.  Over the course of four years, 10 or 11% of the Mediterraneans developed type 2 diabetes, [...]... Read more »

Worst. Antidepressant. Ever.

by Neuroskeptic in Neuroskeptic

Reboxetine is an antidepressant. Except it's not, because it doesn't treat depression.This is the conclusion of a much-publicized article just out in the BMJ: Reboxetine for acute treatment of major depression: systematic review and meta-analysis of published and unpublished placebo and SSRI controlled trials.Reboxetine was introduced to some fanfare, because its mechanism of action is unique - it's a selective norepinephrine reuptake inhibitor (NRI), which has no e........

The where, when, how and why

by Janet Kwasniak in Thoughts on thoughts

A recent review article by Friedemann Pulvermuller looks at what is known about the neurobiology of language. He uses the question of what recent progress has been in the where, when, how and why of language processing in the brain. He does a masterful job and yet I am, personally, disappointed. In what way I [...]... Read more »

The rise and crash of civilizations

by Razib Khan in Gene Expression

One of the questions of interest in the study of the evolution of culture is whether there is a direction in history in terms of complexity. As I have noted before in the pre-modern era many felt that the direction of history was of decline. That is, the ancients were wise and subtle beyond compare [...]... Read more »

Should I lick this?

by PalMD in White Coat Underground

When I lived in Northern California, I would often hear stories about people scouring the back country for psychedelic toads.  In popular imagination, these toad wranglers would then gather around bonfires and with great ceremony and earnestness, they would lick hapless bufoids until they (the humans) fell into ecstatic trances—and then vomited profusely. These stories, [...]... Read more »

One, two, three...ten long-tailed tits

by Africa Gomez in BugBlog

This time of year, the shrill 'see,see,see' contact calls of Long-tailed tit flocks, coming from all directions from the tree canopy. These fluffy, tiny birds have a fascinating breeding system - facultative co-operative breeding - by which individuals may help rear up offspring of others depending of the circumstances. Their breeding season is rather short, and they are only able to rear a single brood per season. In the spring, all individuals pair up and attempt breeding, if breeding fails ea........ Read more »
