A step towards treating advanced cancer

by Cancer Research UK in Cancer Research UK - Science Update

Cancer is a challenging yet fascinating problem for researchers all over the world. And a new paper from US researchers, looking at a way to treat cancer that has spread, shows just how surprising cancer research can be. The research, published in the Proceedings of the National Academy of Sciences (PNAS), shows that an antibody [...]... Read more »

The Blood of Louis XVI

by Terri Sundquist in Promega Connections

A bloody handkerchief stored in an ornately decorated gourd seems like a gruesome keepsake, but that is exactly what scientists are using to obtain the presumptive genetic profile of King Louis XVI of France. “Who would want such an odd souvenir?” you might ask. Well, apparently a bloody handkerchief was a perfectly acceptable memento from [...]... Read more »

Setting the Mood for a Scare

by Psychology 379 bloggers in Cognition & the Arts

Although it lacks the iconic status of Marion Crane’s murder in the shower, the scene in which Detective Arbogast goes to investigate the Bates’ mansion is my favorite part of Alfred Hitchcock’s Psycho. Much of my enjoyment of horror films is derived from the thrill of a good scare, and this scene delivered the desired jolt when I saw the movie for the first time. I remember the sense of foreboding I felt as I watched those tense, unsettling shots of Arbogast walking up the s........ Read more »

Measuring Supply Chain Performance

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Last week I conducted another Interview for the empirical part of my research. And we also discussed how to measure performance within the SC. As it turns out, multiple measures, namely service, cost, working capital are used. Sadly in literature many authors still focus on a single measure only and I wanted to know more about it. So I read an article by B. Beamon (Measuring Supply Chain Performance) to get an overview over performance measures used and how to select the right one(s).

Shock result! Asking children and teenagers to promise to tell the truth actually works

by BPS Research Digest in BPS Research Digest

When teenagers are asked to provide testimonies for use in court, how do you increase the likelihood that they'll tell the truth? It may sound twee, but a North American study claims that merely asking them to promise to tell the truth can be surprisingly effective.

Angela Evans and Kang Lee had just over one hundred 8- to 16-year-olds complete a 10-item trivia test, which unbeknown to the youngsters featured two impossible questions ('Who invented the hair brush?' and 'Who discovered Tunisia?'........ Read more »

Trends and Outcomes of Adolescent Bariatric Surgery

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

Regular readers of these pages will probably be as depressed as I am to see the increasing need for discussing bariatric surgery in kids and adolescents.
Our evident failure to make any discernible headway in preventing childhood obesity has resulted in an increasing number of youth, who are now so severely obese that bariatric surgery often [...]... Read more »

Big Pterosaurs Really Did Fly: Interview with Mark Witton Part II

by Andrew Farke in The Open Source Paleontologist

A new paper in PLoS ONE, by Mark Witton and Mike Habib, re-evaluates claims that big pterosaurs were too big to fly. To make a long story short, multiple lines of evidence suggest that giants like Quetzalcoatlus really did take wing! One of my previous blog posts summarized the paper and featured the first part of an interview with senior author Mark Witton. That part of the interview focused on many of the scientific aspects of the research. Today, we'll highlight some of the other highlights. ........ Read more »

Pouches, pockets and sacks in the heads, necks and chests of mammals, part V: palatal (and other) pouches in camels and gazelles

by Darren Naish in Tetrapod Zoology

Everybody knows that camels are weird. As you'll know if you've been keeping an eye on SV-POW! lately, we've recently been quite taken with their necks. But it's not just camel's necks that are weird. Here, we embark on another look at the sometimes bizarre pouches, pockets and sacs present in certain mammals, most of which are outgrowths of the respiratory system.

Relatively little known is that (some) camels possess an inflatable diverticulum on the palate, termed the dhula, dulaa, gulah,........ Read more »

In short: women want dominant men as short term mates and prestigious men as long term mates. Dominant males being those who are ambitious, assertive and boss other people around, intimidating others. The kind of alpha males chasing desired women. The prestigious kind are those who achieve high social status through social networks (twitter?), making [...]

Prognostic Tool in Pediatric Oncological Hospice

by Brian McMichael, M.D. in Pallimed: a Hospice & Palliative Medicine Blog

In the December 1st issue of Pediatric Blood and Cancer is an article that presents the validation of a prognostic tool in pediatric hospice care. The study was produced by a team from the Hospital A.C. Camargo, a large cancer center in São Paulo, Brazil. Their overall survival rate in the treatment of pediatric cancers is just over 75%, roughly on par with those in the United States at approximately 80%. At this institution, a nurse-led, multidisciplinary palliative care team was developed in........ Read more »

Back pain: It ain’t what you do it’s ….?

Every now and then I stumble across a paper that evoked the reaction “I wish I’d though of that”. Such a paper recently turned up in the journal Rheumatology by Majid Artus and his colleagues at Keele University. They performed a systematic review that aimed to assess not the effectiveness of interventions but instead the [...]... Read more »

Dark Matter Fisticuffs I: The Backdrop

by sarah in One Small Step

On Thursday, two giants of astronomy met in the sleepy German city of Bonn to debate one of the basic tenets of our current cosmological vision: the existence of dark matter. In the blue corner was Simon White aka. the Reigning Champion, Director at the Max Planck Insitute for Astrophysics (MPA) in Garching, and figurehead of the concordance cosmology model we all know and live by. In the red corner, Pavel Kroupa aka. the Challenger, Professor at the Argelander Institute in Bonn and well-known e........ Read more »

Taking a closer look at health encounters for people with chronic pain

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

A theme of comments made by people I’ve seen clinically is that certain health care encounters they’ve had have not been especially helpful. Some people feel belittled, some patronised, some bamboozled, some dismissed – and yet in most surveys of health care satisfaction, the rating is pretty high (Jenkinson, Coulter, Bruster, Richards & Chandola, 2002). … Read more...

Bird song vs urban noise

by davesbrain in Dave Hubble's ecology spot

It's now well known that some birds can adapt their songs to different environments. For example, great tits (Parus major) have been shown to sing faster and at a higher pitch in urban areas (Slabbekoorn & den Boer-Visser 2006). This may be because urban noise, mostly from traffic, tends to be at a lower pitch and drowns out low-pitched birdsong. Also, the relative openness of city landscapes compared to woodland means that high-pitched songs are less likely to be lost in reflections in dense fo........ Read more »

When Organisms Really Shine... Bioluminescence Pt.1

by defectivebrayne in The Defective Brain

As near exclusive surface dwellers, we only see the sun-kissed top layers of the vast oceans of our planet. As we descend into the depths, the light from the sun dies away. And as we reach the bottom, we should be plunged into absolute blackness.
But we aren't. There are lights at the bottom of the ocean....... Read more »
