3:10 PM | Only 10 Percent Of Students Stand Up To Cyber-Bullies - But They Will Give Them A Bad Online Review
In an experiment, 221 college students in an online chat room watched a fellow student get "bullied" right before their eyes but only 10 percent did something about it, either by helping the victim or confronting the bully.Even in the safe online world, modern young people are less inclined than ever to get involved. Using the online equivalent of taking a picture of a victim rather than helping, 70 percent of participants who noticed the bullying gave the bully or the chat room a bad […]

2:25 PM | DIY Titration Lab Ware
You often see demonstrations of titration using an expensive glass burette, but you can build titration lab ware using a disposable serological pipette, a solder sucker bulb, and a ring stand or support stand. For this build I’m using the tripod stand from the Thames and Kosmos Chem C3000 chemistry set. Titration is the process of determining the unknown concentration of a solution by adding a known amount of a solution with a known concentration. read more

When does sobriety for today predict sobriety for a life time? When does the risk of relapse plummet? How long do you have to be in recovery before this risk falls below 15% which is a figure used with other … Continue reading →

2:00 PM | Radio Chip For The Internet Of Things: New Transmitter Reduces Off-State Leakage 100X
The Internet of Things is Web 2.0 of 2004 or Big Data of 2013 - a great buzzword that marketing groups are trying to exploit by rebranding what already exists. But the promise, the idea that everything in the human environment, from kitchen appliances to industrial equipment, could be equipped with sensors and processors that can exchange data, helping with maintenance and the coordination of tasks, is real.Yet there is a huge barrier, in a world that would like to reduce greenhouse gases […]

1:11 PM | Anti-GMO Propaganda
There is so much anti-science propaganda out there I often feel like I am emptying the ocean with a spoon. Just today I was faced with an array of choices for my post – should I take on anti-vaccine, anti-GMO, or anti-AGW propaganda? For today, anyway, anti-GMO won. I’ll get to the others eventually.

12:49 PM | Editors behaving badly?
The H-index is a metric that was devised to identify talented individuals whose published work had made a significant impact on the field (Hirsch, 2005). One of its apparent virtues was that it was relatively difficult to game. However, analysis of publications in a group of journals in the field of developmental disabilities suggest there has been a systematic and audacious attempt at gaming the H-index by a cabal of editors. What's the evidence for this claim? Let's start by briefly […]

9:04 AM | Recruiters think they can tell your personality from your resume. They’re wrong
Recruiters are poor at inferring an applicant’s personality from their resume, but that doesn’t stop them from jumping to conclusions on the back of their flawed assumptions. That’s according to a new study that involved over a hundred professional recruiters evaluating pairs of resumes.The US-based recruiters estimated applicant personality from the limited information in short two-page resumes. Their estimates were poorly correlated with the self-ratings made by the MBA […]

“I’m a statistician,” she wrote. “By day, I work for the census bureau. By night, I use my statistical skills to build the perfect profile.

4:50 AM | Breast Cancer Spread May Be Tied To Cells That Regulate Blood Flow
Tumors require blood to emerge and spread. That is why scientists at The University of Texas MD Anderson Cancer Center believe that targeting blood vessel cells known as pericytes may offer a potential new therapeutic approach when combined with vascular growth factors responsible for cell death. A study lead by Valerie LeBleu, Ph.D., assistant professor, Department of Cancer Biology at MD Anderson, looked at how cellular signaling by vascular growth factors called angiopoietin-2 (ANG2), when […]

3:55 AM | Government Created The Drug Discovery Problem - Now People Want Government To Fix It
The discovery, development and approval of new drug treatments has been stymied. Bureaucracy, coupled with a short patent window and attorneys waiting to pounce, has led to increased interest in vaccines, which require a separate litigation process than just filing a lawsuit and collecting a settlement, or obscure diseases guaranteed to have high payouts - the home run strategy. And the when the public is not reading about how an FDA-approved drug hurt someone, or reading how drug […]

11:25 PM | Humans in the Wild.
This recent publication comes out of the lab of my graduate mentor. We actually brainstormed this experiment over libations on Bourbon Street in New Orleans. Sometimes, the best science comes to mind outside of the lab and when your guard is down. Anyways, Adam, DG, and a group of undergrads sorted through the power grid of […]

9:56 PM | African-Americans May Not Trust Flu Vaccines
A survey asking if people took a flu vaccine revealed some interesting statistics - if their physician specifically recommended it, they were far more likely to have gotten one and vaccination rates among African-Americans was a low 62 percent.90 percent of patients received vaccination if their physician advocated for it compared to 58 percent of patients whose physician did not, the results showed. Vaccination rates in European-Americans were 93 percent and in Asian-Americans 84 […]

9:26 PM | A Side-Effect Of Antibiotics May Not Be A Side-effect At All, It May Be A Feature
Just about everyone in the developed world has taken an antibiotic to treat a bacterial infection and the instructions are well-known; don't stop after you start to feel better, even though you know they are killing machines.Yet the picture may be more complex, according to a new paper, and it might change our understanding of why bacteria produce antibiotics in the first place. "For a long time we've thought that bacteria make antibiotics for the same reasons that we love them - because […]

9:21 PM | Brain waves help memory formation
Our brains generate a constant hum of activity: As neurons fire, they produce brain waves that oscillate at different frequencies. Long thought to be merely a byproduct of neuron activity, recent studies suggest that these waves may play a critical role in communication between different parts of the brain. A new study adds to that […]

6:55 PM | How Posture Can Affect the Brain
For decades now, scientists have had a good knowledge of the descending neural and hormonal pathways by which the human brain influences the human body. But until quite recently, there was still a tendency to underestimate just how much the human body influences the human brain. In an experiment reported in 2010, however, social psychologist [...]

4:57 PM | If You Smoke 15 Cigarettes In A Closed Car, You Could Pass Out
A new paper based on a series of theoretical calculations using applied physics says that if you smoke 15 cigarettes in a sealed car in just over an hour, you could lose consciousness.So crack a window. Or don't smoke in a car. Or don't smoke.Why create the estimate? Starting this October, drivers in England will be banned from smoking in their cars if they are carrying children as passengers and the reason was not just because of vague epidemiological claims about second-hand or even […]

Like sports, want to play into old age without the injury risk?

Mindfulness meditation practices resulted in improved sleep quality for older adults with moderate sleep disturbance in a clinical trial comparing meditation to a more structured program focusing on changing poor sleep habits and establishing a bedtime routine, according to an article published online by JAMA Internal Medicine. Sleep disturbances are a medical and public health concern for our nation's aging population. An estimated 50 percent of individuals 55 years and older have some sort of […]
