Here we go again. A new study which investigated so-called addictive effects of food got picked up by the media with moronic headlines. The study in question found similar pharmacokinetic properties (e.g. concentrated dose, rapid rate of absorption) between highly processed foods and drug of abuse. The most rewarding food was found to be pizza, but in fact the researchers found cheese is actually the proxy. Apparently, cheese contains a concentrated amount of a protein known to bind to opiate receptors in the brain. Unsurprisingly, here are some of the headlines we've seen since: "Cheese really is like crack: Study reveals the food triggers the same part of the brain as drugs" (Daily Mail) or "Cheese really is crack. Study reveals cheese is as addictive as drugs" (LA Times). It goes without saying that cheese is not crack, and such headlines could be actually demeaning to crack addicts.
The thymus is one of those under appreciated organs you just don’t hear much about. Sitting in your chest, just in front of your heart, the thymus is at its largest and most active during infancy and childhood. By adulthood, the thymus has shrunk to practically nothing, being mostly replaced by fat. It plays an […]
A team at University of British Columbia claims that a type of clay found northwest of Vancouver is effective against a dangerous class of drug-resistant bacteria. The clay investigated by the Canadian researchers destroyed the ESKAPE germs, in some instances in less than 5 hours. Furthermore, the clay is completely natural and no toxic side-effects have been reported thus far.
University of Florida researchers have discovered how our bodies control dopamine transport in and out of brain cells.
Researchers in China have genetically engineered autistic monkeys which exhibit almost no social interaction.
Researchers found a way to manipulate single cells in three dimensions using sound waves. They devised acoustic tweezers that can position minute particles or cells anywhere within the fluid enclosure without touching, altering, deforming or labeling the particles in any way. The resolution or accuracy is between 1-2 micrometers. Work like this might enable us to design tissue implants which faithfully mimic the human tissues or organs destined to be replaced. Other methods, like 3D biological printing, alter or even destroy cells keeping them from functioning the way they ought to.
Scientific American recently reported that the three countries most affected by dengue fever have approved the use of the first vaccine against this affliction. Officials from Mexico, Philippines and Brazil hope that this will curb the nearly 400 million new infections each year, 22,000 of which result in death.
A study from Emory University looking into prairie voles' consoling behaviors provides new evidence in support of animal empathy. The tests had pairs of voles isolated from each other, one being exposed to mild electric shocks, to study how the rodents react to a distressed mate.

Why would you eat snow in the first place? Because it's fun and harmless. It's free ice cream. A new study, however, suggests snow isn't as pure as we care to think. Being colder, the temperature gradient leads noxious pollutants expelled from the tails of vehicles to become absorbed by the snow, and in your organism if you decide to eat it. That being said, if you're having fun in the park, it's better not to eat it. We don't know yet how harmful this is, but ingesting benzene, ethylbenzene, toluene, and xylenes mustn't be good.
Scientists are experimenting with a novel mechanism that destroys harmful bacteria that uses light-activated nanoparticles. These are called quantum dots and are typically used by the semi-conductor industry, in solar cells and other applications. When specifically tweaked in size and composition, these tiny particles interact with cells and kill over 90% of bacteria.
Creative thinking requires the simultaneous activation of two distinct networks in the brain, the associative and normative networks. Higher connectivity between these completely different systems of your brain leads to new, original and useful ideas, University of Haifa research concludes.
A new paper published in the Journal of Personality and Social Psychology examines women's efforts to guard their mates from sexual competition -- especially other ovulating females.
Those suffering of migraine headaches reported these occurred less frequently after they were prescribed medical marijuana. The study made by a team at the Skaggs School of Pharmacy and Pharmaceutical Sciences at the University of Colorado Anschutz Medical Campus is the first to show marijuana actually turned down the knob on migraines.

In an unfortunate turn of events, a new Ebola fatality has been reported just hours after West Africa was declared Ebola-free.
Johns Hopkins researchers have discovered a method that allows them to coax stem cells to morph into retinal ganglion cells. This type of nerve cells reside in the retina and transmit visual input from the eyes to the brain. If these cells become damaged or die vision-loss conditions develop, such as glaucoma or multiple sclerosis.
Researchers at University of California, Los Angeles (UCLA) surveyed hunter-gather communities in Africa and South America which practice a traditional lifestyle thousands of years old and found they slept an average of six hours and 25 minutes per night.
University of Montreal Hospital Research Centre (CRCHUM) scientists have identified a new enzyme that could protect the body from toxic levels of intra-cell sugar. When there is too much sugar in the body it gets processed to glycerol-3-phosphate, a buildup of which can damage internal organs. The team behind the study proved that G3PP is able to extract excess sugar from cells.
Researchers have developed a digital audio platform that can modify the tone of the people who are talking.
The world's largest food and water producer will be sued for allegations that it used child slaves to harvest cocoa beads in the Ivory Coast in Africa.
The government has declared a state of emergency in the most affected areas while scientists are trying to figure out why so many babies are born with this often lethal condition.
When faced with a risky decision, like gambling, some people falter and become very cautions, while others get super excited. As it happens, this trait of character may be determined by the strength of the connection between key brain areas of the brain. It's not only drugs that cause addiction -- gambling is psychologically addictive and can be just as dangerous as substance abuse. Three to five gamblers out of every hundred struggles with a gambling problem and as many as 750,000 young people, ages 14 to 21 has a gambling addiction. The findings might help therapists devise better measures. At the same time, using brain scans doctors can finally see whether their patients are making any progress.
Brain scans of nearly 200 adolescent boys recorded as part of a new study performed in South Korea show that compulsive video game players have radically different wiring in their brains, most notably increased communication (known as hyperconnectivity) between several functional brain networks.
Some 50,000 years ago Homo sapiens, Neanderthals and Denisovans co-existed, mingled and interbred. While only the human lineage exists today, these inter-species third degree meetings left a permanent mark on our genome. For instance, an ancient human who lived in what is today Romania had 9% Neanderthal DNA. Today, most Europeans and Asians have between 1 to 4 percent Neanderthal DNA.
Columbia University researchers have successfully identified the cellular network that allows mice to remember which environments are safe and which are dangerous. The study also looks into what happens when these neurons are tampered with, offering insight into how conditions such as PTDS, panic attacks and anxiety disorders can be treated.
The prevailing assumption is that mothers who birth more children live short lives due to accelerated biological aging. Researchers turn this historical thinking upside down after they found having more offspring actually prolongs the life of mothers and slows down cellular degradation.
Schistosoma mansoni might not as famous as other nasty parasitic worms like flatworms or roundworms, but outside the U.S. this pesky bugger infests more than 200 million people. Symptoms range from rash to organ damage to paralysis. For years, patients have had to rely on drugs that ward off the infection, but for remote or communities in the developing world this may be out of the question. There's a widely available remedy found almost anywhere in the world though, according to Egyptian researchers. And it's so cheap that it literally grows in the ground: garlic.
A new study looking into how Mexico's soda tax is impacting consumer habits one year after implementation. The results show a decrease in sugar-sweetened beverage consumption accompanied by an increase in sales of untaxed drinks throughout the country.
A new study, performed at Howard University Medical Center found that practicing the transcendental meditation technique seems to stimulate the production of telomerase, an enzyme associated with reduced blood pressure and heart disease. This correlates well with earlier research which found that meditation techniques reduce rates of high blood pressure, heart attack, and stroke, as well as slowing of biological aging.
Throughout our hunter-forager days, humans have developed a subconscious urge to over-eat and became less and less psychologically equipped to avoid obesity, especially during the winter months, a University of Exeter study recently found.
One of the most exciting gadgets we've seen at CES this year comes from a French startup called DietSensor, which collaborated with an Israeli company called Consumer Physics. Their latest product called SCiO is a pocket-sized device that uses near-infrared spectroscopy to tell you how many carbs or calories are found inside your food.
Even though they can't remember a word in mandarin, children from China adopted in France bear the same brain activity response as bilinguals. Essentially, their brains use the same patterns and neural areas as bilinguals even though by all accounts they must think they're monolingual. The implies that the impact of early developmental experiences on later neural outcomes is much more significant than some might think.
These aren't Christmas lights, but the actual neural activity of Caenorhabditis Elegans, a parasitic nematode. The brain imaging was done by researchers at Princeton University, and no worm had to be cut open. Instead, the researchers used a special protein which fluoresces in response to calcium.
Scientists find the specific brain pathway used by ketamine to relieve depression. Now, it's possible to design a new drug like ketamine, sans "K hole".

In a collaborative effort by the Oregon Healthy and Science University and the University of Pittsburgh researchers have been able to identify the genes whose role is to trigger the onset of puberty, and manipulate them to delay puberty in female rats. They hope that the discovery will help determine exactly why causes early-onset puberty in females.
For more than 200,000 years humans and face mites trace a common history. There’s no human that doesn’t feed these tiny arachnids with some of our delicious face oils, which might startle some. Fret not since these are mostly harmless (though some people are more sensitive to the mites and get rosacea and blepharitis). What’s startling […]
Researchers at the Washington University School of Medicine in St. Louis, looking into the effects depression has on the brain have found proof linking the disorder with abnormal brain development in preschoolers. Their study, published in the journal JAMA Psychiatry, shows how gray matter is thinner and lower in volume in the cortex, an area of the brain that plays a key role in processing emotions.
Northwestern University neuroscientists have developed a method that allows them to pinpoint communicating neurons in a living fly's brain -- effectively paving the way for mind-reading. Their mapping of specific neural connection patterns could provide insight into the computational processes that underlie the workings of the human brain.
