Cell[phone] Cancer?

by A. Goldstein in WiSci

No longer are households filled with cries of, “Stop tying up the phone line! I need to make a call!” The advent of cell phones has enabled anyone to talk anywhere, anytime, for any amount of time. As convenient as these devices may be for our schedules, they might not be so good for our [...]... Read more »

Simon Baron-Cohen, Empathy, and the Atrocities in Afghanistan

by The Neurocritic in The Neurocritic

From Rolling Stone MagazineAn excerpt from Simon-Baron Cohen's new book, Zero Degrees of Empathy: a New Theory of Human Cruelty, appeared as The science of empathy in the Guardian. Overall, the writing revealed him to be unempathetic in some respects, particularly with regard to people with borderline personality disorder1 (BPD):Unempathic acts are simply the tail end of a bell curve, found in every population on the planet. If we want to replace the term "evil" with the term "empathy", we h........ Read more »

Don’t Judge a Cheetah by Its Spots: New Insights into the Genetics and Evolutionary History of African and Asiatic Cheetahs

by Kelly Grooms in Promega Connections

The genetics of wild cheetah (Acinonyx jubatus) populations has a special significance for me. In fact, it could be said that the population genetics of cheetahs changed my life.  I first learned about the low genetic variability in cheetahs in a darkened lecture hall at Iowa State University in 1988. I was so fascinated by [...]... Read more »

Doing kinetics in vivo and in vitro - what can go wrong?

by Vasili Hauryliuk in stringent response

When you study an enzyme-catalyzed reaction happening in the cell, there are basically 3 things you want to know:1) how fast?2) how sensitive to the substrate concentration?3) how specific?In terms of the Michaelis-Menten kinetics that would be kcat, KM and kcat/KM. These all can be measured in vitro, given that you can purify your protein of interest and set up an assay to follow the reaction. But that's in vitro, you say, and how about in vivo? May be everything is different there? What a plea........ Read more »

Could your favorite jeans help catch your murderer?

by Doug Keene in The Jury Room

If it’s true, we would then have favorite jeans posthumously. Would that be too cool or simply bizarre? Either way, it may soon be true! Scottish researchers are looking at ways to recover “fingerprint ridge detail and impressions from fabrics”.  Doing so has been an elusive goal and the success has come with a technique [...]

Trick of the Trade: Steristrip-suture combo for thin skin lacerations

by Michelle Lin in Academic Life In Emergency Medicine

Lacerations of elderly patients or chronic corticosteroid users can be a challenge because they often have very thin skin. Sutures can tear through the fragile skin. Tissue adhesives may not adequately close the typically irregularly-edged laceration.How do you repair these lacerations?Do you just slap a band-aid on it?Trick of the Trade:Use a steristrip-suture combination approach.Apply steristrips to reapproximate the wound edges. Reinforce the steristrips with suture material, as demonstrated........ Read more »

Sweaty work in the hunt for the brain basis of social anxiety

by BPS Research Digest in BPS Research Digest

Social anxiety has overtaken depression to become the most commonly diagnosed psychological disorder in the United States. Part of the cause is thought to be related to bad experiences - being laughed at in class, blushing in front of friends, choking on a first date - so that a person learns to fear social situations. But that's unlikely to be the whole story. Social anxiety runs in families suggesting some people have an innate predisposition for the disorder. The authors of a new study believ........

Wherein Mike, Jess and Morgan discuss Priming. Priming is activation of implicit cognitive constructs in such a way as to influence the behaviour of an individual.

A new paper in Conservation Letters calculates that the numbers of whales and dolphins killed in BP's Deepwater Horizon disaster could be 50 times higher than the number of carcasses found. The authors—a high-powered list of renowned cetacean researchers from Canada, the US, Australia, and Scotland (including Scott Krause, who I filmed years ago for a documentary about North Atlantic right whales)—write of a general misperception of the Deepwater Horizon impact:Many media reports have sugge........

Tip of the Week: MetaPhoOrs, orthology and paralogy predictions

by Trey in OpenHelix

The researchers and developers at PhylomeDB haven’t rested on their laurels. I did a tip of the week on PhylomeDB 3 months ago and not too long ago I was checking over there and found the team had created another useful database and analysis tool, MetaPhoOrs. What is MetaPhoOrs? To quote from the homepage:
MetaPhOrs is a public repository of phylogeny-based orthology and paralogy predictions that were computed using resources available in seven popular homology prediction services (Phylome........ Read more »

Neury Thursday (Tuesday): Sleep Deprivation Activation of Reward Areas

by Allison in Dormivigilia

Neuroscientists at Berkeley and Harvard have observed that acute episodes of sleep deprivation concurrent with the presentation of positive-evoking stimuli are associated with hyperactivation of mesolimbic reward areas. This observation in humans lends further credence to sleep/drug addiction interactions that have been documented on numerous occasions in animal models. It may also further convince physicians to recommend sleep/circadian rhythm therapies for the treatment of drug addiction and r........ Read more »

ACUPUNCTURE: The last word on acupuncture? If only!

by Paul Ingraham in SaveYourself

Acupuncture fail
Not so popular, ancient, safe, or effective after all.
The journal Pain, one of the top ten journals for pain and injury science, has published a thorough and harsh scientific smack down of acupuncture, concluding that there is “little truly convincing evidence that acupuncture is effective in reducing pain,” and that — alarmingly — “serious adverse effects continue to be reported,” such as infections and collapsed lungs.
