A novel and highly effective technique was found to enhance regrowth of human corneal tissue to restore vision, using a newly identified molecule that acts as a marker for limbal cells – stem cells that are paramount to retinal regeneration. The findings could greatly improve the vision of patients suffering from severe burns, victims of […]

China's self-inflicting arsenic poisoning in pictures

China is the most rapidly developing country in the world. Thanks to the pioneering work and arduous efforts by the People’s Republic of China over the past 50 years, especially over the last 25 years or so since the beginning of reform and opening-up, the overall national strength and the living standards of the people have […]

Scientists genetically screen alleged Yeti samples, find they're from known mammals instead

One of the most popular urban myths speaks of Bigfoot – an 8-foot tall creature, covered in thick, dark hair. The creature, also known as sasquatch or Yeti (the Asian counterpart) has spurred the imagination of countless people, some of whom went a step farther to report actual sightings of the elusive beast. If you […]

Addiction is a disease that first starts with dopamine overcorrection in the brain

Drug and alcohol addiction affects millions of people around the world, but despite decades worth of research and billions of dollars, our understanding of addiction is still far from being complete. Brigham Young University professor Scott Steffensen and his team have recently contributed with a few pieces in the addiction puzzle, which are of vital […]

Part of the brain subjectively encodes information related to human emotions

Primates are among a couple of mammals that have a dedicated system for processing faces, something that involves a lot of neuropower and energy expenditure. While there are people that resemble each other, no two humans have the same exact faces (not even identical twins). Some people see, and thus analyze, thousands of faces each […]

Link found between nearsightedness and years spent in school

A common stereotype is that people who wear glasses are labeled as nerds, but sooner than later most people from the developed world will end up wearing glasses, if the current trend continues. There are many reasons why more and more suffer from nearsightedness, ranging from urbanization, spending more time indoors and in front of […]

Heavily decorated classrooms disrupts attention and learning in children

Cluttered classrooms filled with anything from artwork to ABC boards to portraits – the kind we often see in schools – disrupt attention and learning in young children, according to researchers at Carnegie Mellon University. The study doesn’t necessarily suggest, however, that a sparser decoration should be used. Instead, teachers are advised to be careful how […]

Chimps like African and Indian music - not Western music

Chimps prefer silence to all types of Western music(even classical music), but that doesn’t mean they don’t like music at all. A new study published in the American Psychological Association found that chimpanzees like traditional African and Indian music. “Our objective was not to find a preference for different cultures’ music. We used cultural music from […]

Vietnamese Oral Vaccine for Cholera is highly effective in Africa

A new, inexpensive and easy to use vaccine developed in Vietnam worked very well during a cholera outbreak in Africa, Doctors Without Borders reported. Cholera is an infection of the small intestine caused by the bacterium Vibrio cholerae. It is generally transmitted through through food or water. In the developed world, the main cause is sea […]

Neuroscientists use fMRI scanners to track the brain of experienced and novice writers as they write fiction

Using fMRI machines to peer into the brains of artists is not really a new idea, we’ve even done it to animals as well, so I was quite surprised to see that no one used them to analyze writers as they go through their creative process. But this is exactly what German researchers did now – […]

Strict diet doubles lifespan of worms

Taking food away from C. elegans in larval stages suspends their development; while they still wiggle around and look for food, they are in a state of arrested development. However, when food becomes plentiful again, they start to develop normally – but live twice as long. This remarkably simple way of achieving longevity is not entirely surprising. It […]

Man's hand is grafted onto his foot for transplant

Chinese doctors have grafted a man’s hand onto his food in order to preserve it until they could transplant it back to its rightful place. If a body part becomes severed from the body, there is only a limited period of time before it can be reattached – usually just 2-3 hours. Adding some ice […]

Dr. Oz Admits ‘Miracle’ Diet Products He Advocates Are Pseudoscience

A senate panel interviewed Dr. Mehmet Oz on Tuesday regarding his claims of various ‘miracle’ weight loss cures; as a result of lack of any scientific evidence and a big cloud of suspicion was floating above his head, Oz admitted that there is no actual evidence behind his proposed products. Obesity is the biggest health […]

Food addiction is real, study shows

We’ve written about food addiction several times previously – it’s correlated with impulsive personality, it shares some similarities with drug addiction, and some people become addicted to junk food just by staring at it. But food addiction remained a very controversial aspect, with some scientists claiming that it simply doesn’t exist. Now, a study conducted […]

Job interviews reward narcissists, punish applicants from modest cultures

How do you act when you’re at a job interview? Do you just go and be yourself, showing your true qualities and defects, or is it all a role in which you say what the interviewer wants to hear? According to a new research, sadly, the latter may be the way to go more often […]

Leukemia drug found to dramatically boost immune system

A class of drugs currently used to treat leukemia has been found to have some severe side effects – positive ones, that is. The drug was found to drastically boosting immune responses against many different cancers, reports a new study. The drug class is referred to as p110´ inhibitors. Recently, it has been used with […]

Newborns exposed to dirt, dander, germs may have lower allergy, asthma risk

Infants exposed to more “real” conditions tend to be healthier than those overly protected. A new study has shown that newborns exposed to rodent and pet dander, roach allergens and a wide variety of household bacteria in the first year of life appear less likely to suffer from allergies, wheezing and asthma. If the child […]

Rats show regret after wrong choices, study shows

A new research has shown that rats exhibit behaviors consistent with regret, a feeling once thought to be unique to humans. To measure the cognitive measure of regret, scientists developed a task that asked rats how long they were willing to wait for certain foods. Basically, they made them decide if they want to wait […]

Scientists identify new type of procrastination: Sleep Procrastination

We’ve probably all experimented it: you don’t have anything useful or even fun to do, but you don’t want to go to bed just yet – so you just browse your computer or tablet for a few minutes… or hours. Now, researchers from the University of Utrech have come up with a scientific explanation for […]

Three parent babies: possible in two years

Every baby has a mother and a father, right? As in one of each. Well, that may change soon, according to a new UK report. In February, the FDA announced it was considering 3-parent embryos; while this would be an excellent way to stop some deadly diseases, it also raises many ethical questions, and the reaction (as […]

Marijuana use is associated with impaired sleep quality

We’ve written quite a lot lately about the potential benefits of marijuana (and there are quite a lot), but we shouldn’t idealize it and ignore the downsides: a recent study has shown that marijuana use is associated with impaired sleep quality. It’s not the first time marijuana has been associated with lack of sleep quality. In […]

Currently, he is involved in an fMRI study investigating the functional networks of hallucinogen-induced […]

Cynics are thrice as likely to develop dementia

Optimists make the most of life? A new study has shown that cynics are much more likely to develop dementia in later stages of life. Cynicism is an attitude of scornful or jaded negativity, especially a general distrust of the integrity or professed motives of others. Researchers from the University of Eastern Finland in Kuopio have conducted a […]

Scientists erase memory (and then reactivate it) in rats

Researchers have erased and then reactivated memories in rats, profoundly impacting the animals’ reaction to past events. This is the first study ever to demonstrate the ability to selectively erase and then reactivate a memory by stimulating nerves in the brain at frequencies that strengthen synapses, the connection between neurons. The Eternal Sunshine of the Spotless […]

Five or more blistering sunburns before the age of 20 increase melanoma risk by 80 percent

The risk of possibly the most dangerous type of cancer out there, melanoma, is greatly increased by exposure to sun in early adulthood. According to a new study conducted on Caucasian women, five or more blistering sun burns may increase the risk of melanoma by 80 percent. “Our results suggest that sun exposures in both […]

Amber discovery shows Lyme disease is older than human race

Lyme disease is a stealthy disease, which can be very dangerous, especially if misdiagnosed. It was only recognized officially 40 years ago, but now, a new amber research has shown that the bacteria causing it may have been around for over 15 million years – long before any human was walking on Earth. The study […]

A Third of the World is Now Obese or Overweight

A new study reports that almost 30 percent of the world’s population (2.1 billion people) is now obese or overweight. The highest proportion of overweight and obese people – 13% of the global total – live in the United States, a country which accounts for only 5% of the world’s population. Obesity rates have increased virtually […]

People who excessively share on facebook are more lonely and depressed

Researchers at  Charles Sturt University in New South Wales found a connection between excessive sharing of information on facebook and feeling lonely and/or depressed. This is the latest in a slew of studies that suggest the social network can cause serious emotional damage to some people. The researchers found that 79 percent of users who describe themselves […]

Ant biomechanics might inspire the super robots of the future

Ants are one of the most fascinating and extraordinary organisms on Earth. The ant society is extremely stable, compact and adaptable, but while ants can only survive as a colony, taken individually each ant is extremely remarkable by itself, too. Body size considered, ants are among the strongest beings in the world, capable of lifting […]

Science shows HIV can cut and paste parts in the human genome

For the first time, researchers have modified HIV virus particles so that they can simultaneously, as it were, ‘cut and paste’ in our genome via biological processes. Developed by biologists from the Aarhus University, the technology makes it possible to repair genomes in a new way. It also offers new perspectives for treating several viral infections: “Now […]

Kawasaki disease origin finally traced (probably)

The Kawasaki disease, a strange and highly dangerous disease first identified in Japan has been traced to the croplands in China. Also called lymph node syndrome, the Kawasaki disease is an autoimmune disease largely seen in children under five years of age in which the medium-sized blood vessels throughout the body become inflamed. To oversimplify it, […]

Humiliation may be the most intense of human emotions

If you look back, you’ll find that some of your most treasured memories are linked to powerful emotions, be them positive or negative. Somehow, it may seem that negative emotions linger longer in our lives, long after the event that triggered them passed. Now, research has garnered tantalizing proof that suggests the most intense of […]

Ultra-sensitive chip can detect cancer fast from only a drop of blood

Most cancer diagnosis tools and procedures today involve detecting the disease on the microscopic level. There is no single test that can accurately diagnose cancer. The complete evaluation of a patient usually requires a thorough history and physical examination along with diagnostic testing – a lot and a lot of tests. If that wasn’t enough, […]

3D Bioprinted liver-inspired device traps toxins and detoxifies blood

Inspired by the healing properties of the human liver, researchers at University of California, San Diego created a 3D-printed biodevice which mimics the liver and removes dangerous toxins from the blood. Used outside the body, like a dialysis machine, the device employs nanoparticles to trap pore-forming toxins that can damage cellular membranes. These toxins often result from […]

Mice with multiple sclerosis walk and run again after human stem cell treatment

In a feat that surprised even the scientists who made the experiment, mice disabled by a condition similar to multiple sclerosis (MS) began to walk and even run again after human stem cells had been transplanted. The findings could potentially offer new means of treating MS, a terribly disease which plagues some 2.3 million people worldwide. Growing […]

There probably is no such thing as gluten intolerance, study shows

This is one of those science stories where it gives to show that even scientists can be biased and, most of all, that it’s only when you stand-up and become willing to contradict yourself that you come closer to the truth. Peter Gibson, a professor of gastroenterology at Monash University and director of the GI […]

Shorter men live longer, study shows

While being taller has been correlated with success in life, being short also has its perks: a team of researchers has shown that shorter men tend to live longer. “We split people into two groups — those that were 5-foot-2 and shorter, and 5-4 and taller,” said Dr. Bradley Willcox, one of the investigators for […]

Lucid dreaming easily triggered by zapping the brain at 40 Hz

Some people have very vivid dreams, others can’t remember a thing when they wake up about what they’ve dreamed the night before. It’s said that by studying your dreams, you in fact learn more about your true inner self since dreams are your subconscious’ projections, genuine and unaltered. What happens when you’re fully aware you’re dreaming […]

A recipe for disaster: antimicrobial resistance may lead to dystopian scenarios

A world where even minor infections can kill you, where almost no antibiotics are viable, with superbugs and drug-resistant strains – it’s not a horror movie scenario, but something which may very well happen in the upcoming decades, according to a new report by the World Health Organization (WHO). We’ve written about the threats of […]

New brain cells erase old memories

If you’re trying to hold on to old memories, then some new, fresh brain cells may be the last thing you need – a new research published in Science suggests that newly formed neurons in the hippocampus (an area in the brain responsible for memory formation) could remove previously stored information. This is perhaps the […]

Scientists engineer first living organism with unnatural DNA

The entire living world is “written” with just four DNA bases: A = adenine C = cytosine G = guanine T = thymine However, for the first time, researchers have now created a living cell with an added pair of DNA “letters,” or bases, not found in nature – the DNA alphabet just got some new letters! “Life on Earth […]

New bird flu infects Antarctic penguins

It’s so cold even penguins get the flu in the Antarctic. Seriously, researchers report in a paper published in the journal mBio how they identified a new strain of influenza that infects Adelie penguins which breed in huge colonies on the rocky Antarctic Peninsula. The virus itself seems to be dormant as the penguins don’t exhibit any visible flu […]

Psilocybin, the active substance in magic mushrooms, inhibits the processing of negative emotions in the brain

Negative emotions like fear, sadness and anger evolved serving a purpose – enabling people to adapt to the changing conditions in the environment, reacting flexibly and efficiently to stress and strain. However, in modern society, in certain situations, we’d really like to avoid experiencing those feelings, as well as many others, like depression or anxiety. Researchers […]

Bone marrow-on-a-chip could remove bone marrow animal testing

A new “organ on a chip” has been developed by Harvard researchers, reproducing the structure, functions, and cellular make-up of bone marrow, a complex tissue that until now, could only be studied on living animals. Bone marrow is one of the more complex and fragile parts of the human body – many drugs and toxic elements […]

How humans and squids came to have similar eyes

Humans and squids are not exactly close relatives – as a matter of fact, we’re really different from squids, so how come we came to have surprisingly similar eyes? The answer, as usually, is in our genes. Eyes are complicated things – and like all organs, they rely on many genes working together, keeping everything […]

Electro-magnetic helmet proves great benefits for fighting depression

Danish researchers have developed a special helmet that shoots electro-magnetic waves in target brain regions and treats patients suffering from depression. The results so far have been extremely promising, especially since it seems to work very well for patients suffering from extreme forms of depressions where conventional medicine doesn’t seem to work. According to the World […]

Protein Dracula: transferring young mice blood to older mice reverses aging

This Sunday a trio of landmark studies were published each discussing an aspect of a wider picture:  reversing aging in the muscles and brains of old mice simply by transfusing blood coming from younger mice. The effect is credited to a key protein found in much higher concentration in the blood of younger mice. So far, the findings […]

New circuitboard is 9,000 times faster and more energy efficient at simulating the human brain than PC

A mouse might not look like the smartest animal, but however modest its cortex may seem it’s still 9,000 times faster than a personal computer simulation of its functions. Not only that, but it takes 40,000 times more power to run – energy efficiency being, in fact, the true benchmark that needs to be considered when […]

Study of HIV evolution shows the virus is adapting to human hosts

One of the most threatening modern pandemics, HIV/AIDS, has been thoroughly studied in the past few decades, with billions awarded to research seeking out a cure. Progress has been slow, but today doctors have a number of tools at their disposal to curve HIV development, spreading and ail patients, despite a cure has yet to […]

Taking a walk encourages creativity more than sitting

If you’ve ever read the biographies of some of the world’s greatest thinkers, you may have noticed that one of their favorite pastimes was taking long and relaxing walks. For instance, Charles Darwin had a fixed schedule that demanded he begins his morning rituals with a walk upon waking at 7:00, and only after take […]
