3:59 PM | Teach For America Efforts Show School Board Politics Alive And Well
Teach For America is a group that recruits recent college graduates to teach in poorer public schools for two years, the idea being that they would be better than substitute teachers in those districts. Education unions dislike the organization and call them 'scabs' - because they are non-union labor. Now, Teach for America is setting its sights on capturing school board seats across the nation. They are never going to win over an education union that wants to protect tenure and jobs, but if […]

3:23 PM | First Grade Reading Suffers In Minority Neighborhood Schools
Beginning in 1969, a court decision, motivated by a lack of racial integration in schools, led to students being shipped to schools in other neighborhoods. As part of a political campaign against Richard Nixon, his political opposition latched onto this forced busing and school desegregation to show they cared about minorities more. The trade-off was that kids were no longer in their own neighborhoods and felt like pawns in a culture war.read more

3:15 PM | Treating Sleep Problems Following Traumatic Brain Injury
Sleep problems are common following traumatic brain injury (TBI).In a previous post, I reviewed a study of the risk factors for sleep disorders following TBI.The most severe TBI is a risk factor for hypersomnia. Anxiety and depression following TBI increase risk for insomnia complaints.Few large studies of treatment for sleep problems after TBI exist. However, a recent manuscript outlined the potential benefit of treatment of sleep disorders in a series of 12 subjects.Catherine […]

12:28 PM | What makes some children of alcoholics vulnerable, and some resilient?
I come from a family of four siblings, two of whom are alcoholic and two who are not. I have often wondered why this is the case? Why is it the case that certain children of alcoholic parents will grow up to become alcoholics and why some will not? What is it that makes certain […]

12:17 PM | Reward and Punishment in the Brain
In a recent study, scientists looked at the brain with high resolution fMRI scanning while they showed subjects pictures. Following each picture was a painful electric shock, or a money reward, or no response, or a random response. Subjects quickly learned which pictures would be followed by which stimuli – positive, negative, neutral, or unpredictable. [...]

11:00 AM | Water Vapor Is The Most Abundant Greenhouse Gas
Though many people believe that CO2 is the most abundant greenhouse gas in the atmosphere, that honor actually goes to water vapor. NASA has been saying for years that water vapor is the biggest amplifier in global warming, perhaps double the effect of CO2,  and a new study from scientists at the University of Miami confirms rising levels of water vapor in the upper troposphere will intensify climate change impacts over the next decades.read more

11:00 AM | NFL Players: Here Is The Best Time To Sign A Contract
In the NFL. there is a salary cap and while money in contracts can be guaranteed, the contract itself is not. For people outside the US this makes no sense but basically every contract has a bonus, which is guaranteed, and then an annual salary, which is not. A team can waive a player and the money of the bonus counts 'against the cap' while the annual salary is prorated.read more

9:06 AM | Remembering together - How long-term couples develop interconnected memory systems
Although it might seem a good idea to work with other people to remember important information, the evidence suggests that this typically isn't so. Individual recall is most efficient whereas social remembering comes with drawbacks, tripping up our flow and inhibiting memories. But this evidence mostly comes from asking people to collaborate with a stranger. What happens when you know each other really, really well?Celia Harris and colleagues at Macquarie University recently reviewed their […]

2:25 AM | Evidence Of Man At The South Pole Before Roald Amundsen Arrived In 1911
The South Pole is the spot in Antarctica at 90 degrees S, where the surface of the earth intersects the axis of rotation. Except for inside the United States Amundsen-Scott South Pole Station, there is no plant or animal life. Norwegian explorer Roald Amundsen arrived in 1911 but evidence of man had already beat him there - in the form of industrial air pollution that arrived long before any human.read more

12:00 AM | Running Was Never As Great As Once Claimed, But Not As Bad As Now Said Either
Running was once a big health fad. Like red wine and chocolate on the miracle side, or wheat and sugar on the panic side, mainstream media is happy to build up fads so they can tear them down later. Modern stories revolve around people dropping dead from running but you are a lot less likely to die running, even if for only a few minutes a day at slow speed, than you are sitting around eating Doritos.read more

11:55 PM | Attention Deficit Hyperactivity Disorder & Eating Disorders: Is There a Link?
Attention deficit hyperactivity disorder (ADHD), characterized by inattention, hyperactivity, and impulsivity, is a common childhood disorder. ADHD can often persist into adolescence and adulthood. The prevalence of ADHD is thought to be between 6-7% among children and adolescents and ~5% among adults (Willcutt, 2012). Increasingly, evidence from multiple studies has pointed to comorbidity between ADHD and eating disorders (EDs). For example, one study found that young females with ADHD were […]

10:00 PM | For People At Risk Of Suicide, The Internet Is A Blessing And A Curse
There are websites that encourage anorexia, there are websites that glorify stepping on animals with high heels and killing them, so it is no surprise that there are websites that glorify suicide. There are also websites that can talk people down from the ledge. In a free Internet, they can both be found rather easily.An upcoming paper looked for information on suicides using popular search engines (Google, Bing) in Austria and the USA and found that protective information is significantly more […]

9:34 PM | Endurance Runners: In Warm Regions, Heat Stroke 10X More Likely To Kill You Than Heart Attacks
Since emerging from the primordial ooze, organic life has been doing unnatural things in defiance of nature. Nothing is as unnatural as endurance running but sentient beings like to push boundaries. Endurance running is impressive, but it is risky. There are calls for pre-participation electrocardiogram (ECG) screenings because of an alarming number of sudden death occurrences in athletes. including undetected heart disease in a young and seemingly healthy people, but it turns […]

9:08 PM | Astrocytes, The Brain's Lesser Known Cells, Get Some Cognitive Respect
When something captures your interest, like this article, unique electrical rhythms called gamma oscillations sweep through your brain. These gamma oscillations reflect a symphony of cells—both excitatory and inhibitory—playing together in an orchestrated way. Though their role has been debated, gamma waves have been associated with higher-level brain function, and disturbances in the patterns have been tied to schizophrenia, Alzheimer's disease, autism, epilepsy and other […]

7:30 PM | Discovered: Cool-Burning Flames In Space
If you have watched the NASA channel recently, you might have witnessed a series of experiments regarding flames.  On the surface, pardon the pun, it may have seemed like a minor thing, but how flames behave outside our atmosphere has led to discovery of a new type of cool burning flames.  A better understanding of the cool flames' chemistry could help improve internal combustion engines in cars, for example by developing homogenous-charge compression ignition. read more

6:53 PM | Watch ALL the neurons in a brain: Ahrens and Freeman continue their reign of terror
Okay, not quite all of them. But it looks like Misha Ahrens and Jeremy Freeman are going to continue their reign of terror, imaging the whole zebrafish brain as if it’s no big deal. Yeah they’ve got almost every neuron of a vertebrate, so what? Besides figuring out that not shooting light at the eyes might […]

6:36 PM | The NSA, Snowden, And Citizen Cryptology
In a previous article I demonstrated how to use a One Time Pad cipher using a pen, paper, and Scrabble tiles (or Boggle cubes). If used correctly, One Time Pads cannot be broken by the NSA or any intelligence service on Earth because the One Time Pad keys use a randomly generated set of letters or numbers to encrypt your message. read more

6:00 PM | Goal Attainment: We Often Don't Like Early Victories
If most people run a race, they cheer after they cross the finish line. It is a culturally acceptable psychological reward for all of the training and preparation and execution of the plan. But what happens when that script isn't followed? If you learn of a victory too soon, is it cheapened? Ayelet Fishbach, a professor of behavioral science and marketing at the University of Chicago Booth School of Business, and Nadav Klein, a doctoral student, find that the positive reaction one would have […]

5:01 PM | Scissoring The Lipids May Lead To Tuberculosis Vaccine
A new strategy enables molecules to be disconnected essentially anywhere, even remote from functionality.   The organic synthesis strategy, developed by Professor Varinder Aggarwal and Dr Ramesh Rasappan in the School of Chemistry, involves a new method for combining smaller fragments together in which there is no obvious history in the product of their genesis. Their paper describes not only this new strategy, but also its application to the shortest known synthesis, just 14 steps, of […]
