9:01 PM | Mom Was Almost Right: Junk Food Will Spoil Your Appetite, Except Permanently
A diet of junk food not only makes rats fat, but also reduces their appetite for novel foods, a preference that normally drives them to seek a balanced diet, according to a study in Frontiers in Psychology which helps to explain how excessive consumption of junk food can change behavior, weaken self-control and lead to overeating and obesity.read more

9:01 PM | Old Tires Lead To Better Anodes In Lithium-Ion Batteries
In the 1970s, Florida environmentalists who had invented the notion that landfills were going to overrun America came up with the idea of making coral reefs out of tires. A few short decades later, the clean-up costs when those all came loose were 100X the supposed savings and tires have fallen out of favor as clever quick fixes since then. Leave it to people in Tennessee to find a new use for old tires.  Oak Ridge National Laboratory researchers have found a way to use them to make […]

8:53 PM | This is your Brain. This is your Brain on Drugs
Drugs are bad for the brain. That is (excuse the horrible pun) a no-brainer, but while scientists have seen the after effect drugs have on the brain, we have never […]

8:00 PM | Oxidized Lipids: Protein In HDL May Be Key To Treating Pulmonary Hypertension
Oxidized lipids are known to play a key role in inflaming blood vessels and hardening arteries, which causes diseases like atherosclerosis. A new study at UCLA demonstrates that they may also contribute to pulmonary hypertension, a serious lung disease that narrows the small blood vessels in the lungs. Using a rodent model, the researchers showed that a peptide mimicking part of the main protein in high-density lipoprotein (HDL), the so-called "good" cholesterol, may help reduce the production […]

7:30 PM | E-Cigarettes Versus Cigarettes: 10X Decrease In Second-Hand Smoke
In the culture war on cigarette smoking that lingered long after the science and health issues were settled, nothing spoke to the fuzzy, non-evidence-based nature of arguments than claims that second-hand smoke would give someone lung cancer. Cigarette smoking is annoying and smelly, to be sure, and asthmatics can't be happy in a smoke-filled room any more than non-smokers are, but there are no instances where second-hand smoke has caused cancer. The American Heart Association recently went to […]

7:30 PM | Zombie Bacteria Invasion? Nothing To Worry About
Cellular reproduction seems simple but the ability to faithfully copy genetic material and distribute it equally to daughter cells is fundamental to all forms of life - and complex. Even seemingly simple single-celled organisms must have the means to meticulously duplicate their DNA, carefully separate the newly copied genetic material, and delicately divide in two to ensure their offspring survive.read more

6:42 PM | A Further Note on "Contagious Shooting"
In my recent history of "Contagious Shooting," I suggested that mechanical metaphors would be mobilized in media discourse to shape further public attitudes about the physiological nature of police over-reaction. Yesterday, Joel F. Shults, writing in The Washington Post, delivered this fine nugget:Brain processes take time and often move slower than reality. A study published in 2003 showed that it takes a shooter about one-third of a second to recognize a threat, then each […]

6:36 PM | Non-Adaptive Evolution In Cicada Gut: 2 Genomes Function As 1
Organisms in a symbiotic relationship will often shed genes as they come to rely on the other organism for crucial functions but researchers have uncovered an unusual event in which a bacterium that lives in a type of cicada split into two species - doubling the number of organisms required for the symbiosis to survive.read more

6:00 PM | The Saddam Tapes: Hussein Was A Mass-Murdering Despot, But A Sincere One
Politicians often say one thing in public and other things in private. That is no surprise, people in all jobs do the same thing. Saddam Hussein, the genocidal former dictator of Iraq, has left a legacy most despots do not; he recorded so many of his private conversations that political scientists can analyze what he said in private and compare those to his public statements. Their conclusion; he believed what he said.read more

6:00 PM | Better At Computer Games? You Probably Have A Better Vocabulary
It is not a "All your base are belong to us" world in video games any more. Today, if you want to make a mark in the world of computer games you had better have a good English vocabulary, according to a study by the University of Gothenburg and Karlstad University, Sweden. And games do. The study confirms what many parents and teachers already suspected: young people who play a lot of interactive English computer games gain an advantage in terms of their English vocabulary compared with […]

6:00 PM | Ontario Is A Worldwide Inflammatory Bowel Disease Hub
Why do so many people in Ontario have inflammatory bowel disease? One in every 200 Ontarians has been diagnosed with IBD, an increase by 64 percent between 1999 and 2008, according to a study by researchers at the Institute for Clinical Evaluative Sciences (ICES), the Children's Hospital of Eastern Ontario (CHEO), and the Ottawa Hospital Research Institute. That puts Ontario in the 90th percentile for IBD prevalence in the world. The study in Inflammatory Bowel Diseases is the first and […]

4:48 PM | Schrödinger's Picture: Researchers Take An Image Without Ever Detecting Light
Here is something counter-intuitive: researchers have developed a new quantum imaging technique in which the image has been obtained without ever detecting the light that was used to illuminate the imaged object, while the light revealing the image never touches the imaged object.  As everyone knows, outside the world of quantum mechanics, to obtain an image of an object one has to illuminate it with a light beam and use a camera to sense the light that is either scattered or […]

4:25 PM | How Does It Feel To Be Old In Different Societies?
People aged 70 and over who identify themselves as 'old' feel worse about their own health in societies where they perceive they have lower value than younger age groups. New research from psychologists at the University of Kent, titled 'Being old and ill' across different countries: social status, age identification and older people's subjective health, used data from the European Social Survey. Respondents, who were all aged 70 and over, were asked to self-rate their health.read more

4:04 PM | Iron Age: Workers At Slaves' Hill Were Not Slaves
In 1934, American archaeologist Nelson Glueck named one of the largest known copper production sites of the Levant, located deep in Israel's Arava Valley, "Slaves' Hill." This hilltop station seemed to bear all the marks of an Iron Age slave camp – fiery furnaces, harsh desert conditions, and a massive barrier preventing escape, but new evidence uncovered by Tel Aviv University archaeologists overturns that narrative and says the people there were instead highly regarded craftsmen rather […]

2:16 PM | Nasal Septum Cells: From Nose To Knee, Engineered Cartilage Regenerates Joints
Human articular cartilage defects can be treated with nasal septum cells because they are able to adapt to the environment of the knee joint and can thus repair articular cartilage defects.  The nasal cartilage cells' ability to self-renew and adapt to the joint environment is associated with the expression of so-called HOX genes. The scientific journal Science Translational Medicine has published the research results together with the report of the first treated patients. read more
