I have never in my life eaten a crab or a lobster, because ever since I was a kid, boiling an animal alive seemed extremely cruel; it just didn’t make sense that an animal doesn’t feel pain – and even today, it doesn’t, to me. Pain is your body’s way of telling you something is […]
A few years ago ZME Science reported how a group of researchers at University of Maastricht in Holland were on a mission to grow the first lab cultured ‘hamburger’. After five years of painstaking work and €250,000 invested (backed by Google’s Sergey Brin), an edible version was finally developed and what better way to put it to […]
Temperature is an important physical parameter which greatly influences a system. Monitoring and/or manipulating this state parameter with great accuracy is thus of great importance to scientists. Recently, researchers part of DARPA’s Quantum-Assisted Sensing and Readout (QuASAR) program proved a new technique that allowed them to measure and control temperatures at the nanometer scale inside living cells. Measuring […]
A new study performed by scientists in China has further elevated stem cell research after they successfully grew teeth-like structures using cells derived from an unlikely source: urine. Eventually, they hope that human stem cells could provide the basis for a tooth bud that could be transplanted into the jaw of the patient. Some of you […]
Weighing in at 33 pounds (15kgs), this huge honey mushroom was recently discovered by locals in China’s Yunnan Province. Specialists aren’t sure yet, but the giant fungus could actually be a record breaker. The large clump of mushrooms, which numbered over 100 caps attached at the base of their stems, caused quite a stir amongst […]
How many times did you apply for a job or to enter a graduate program in some school somewhere only to find that the position was filled by someone less capable than you? Now, we’re strictly referring to people genuinely less capable than you, otherwise we’d be hitting the same bias exhibited by the manager […]
It’s no easy task for any psychologist to bear the news to a parent that his child is suffering from autism. For the parent, receiving the news is much worse. Not all hope is lost, however, as it’s been reported that a promising fraction of those diagnosed with autism eventually recover during young adulthood, despite […]
Studying death in humans has always been precarious. I mean, it’s not like anyone would volunteer to be live dissected as they slowly die, and even if someone would agree to such a procedure, most likely it would not be allowed. Not in any western hospital anyway. Luckily, death is such a common, as in […]
Most smokers fall prey to the poisonous grasp of cigarettes because they became seduced by the simple act itself, not because of the taste or other pleasures relieved from smoking. There are many aspects that make smoking extremely appealing, especially to attention-seeking young. Despite several policies have been introduced in the past decades to put […]
Biotech giant, Monsanto, has been met with a wave of furious protests during the past year in Europe, as the company intended on introducing genetically modified seed crops in the EU. As opposed to the US, where despite the general public is nearly or just as adverse in the face of genetically modified crops, politicians […]
Scientists have striven for years to comprehend the complicated neurological mechanisms that underline the human brain and consciousness. Besides the philosophical aspects of such a quest (how we do think? what is consciousness born?), a better understanding of the human brain will help solve a number of medical issues that currently plague the human brain. […]
Society today is becoming ever stressed out it seems. According to a recent American Psychological Association poll, nearly a quarter of Americans confessed to currently feeling under “extreme stress,” however not all of us are as stressed under the same conditions. For instance, there’s a general consensus in the medical world that women are better at […]
The insertion of one gene can shut down the extra chromosome which causes Down Syndrome, according to a study published today in Nature. A dreadful disease Down Syndrome (DS), also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. It’s the […]
Researchers at Harvard-affiliated Massachusetts General Hospital (MGH) have successfully grown and inserted functional blood vessels into animal models after they used vascular precursor cells derived from human induced pluripotent stem cells (iPSCs). These blood vessels lasted for as long as nine months, much longer than any previous attempt, making the Harvard researchers’ efforts seem extremely promising. Patients […]
It may not seem like much, but by differentiating between bacterial and viral fevers, this new test could help doctors decide whether or not to prescribe antibiotics. Fevers are a common symptom in many infectious diseases, but it’s often difficult to know if the cause is bacterial or viral, and thus, antibiotics are often needlessly […]
An extremely challenging study published by a team of researchers from the Stanford School of Medicine claims that through some unknown mechanism mammals can bias the sex of their offspring in order to win the genetic lottery and produce extra grandchildren. The holy graal of modern evolutionary biology After analyzing 90 years of breeding records […]
Less than 1.5 percent of our DNA is used in a conventional way, that is to encode for proteins – this was the common sense around this issue 10 years ago; recently, previous research has shown that 5-8% of the genome is conserved at the level of DNA sequence, indicating that it is functional, but […]
Autism is one of the biggest medical mysteries of the 21st century, and researchers are still trying to figure out the causes of this condition. UC Davis MIND Institute researchers have made a significant step forward in that direction, identifying some specific antibodies that target fetal brain proteins in the blood of women with autistic […]
A recent study released by the Yale Rudd Center found that billions of food and beverage related ads that promote unhealthy products are being served to children visiting popular children’s websites like nick.com or cartoonnetwork.com. This is the first study that assess the content of banner ads and other related media advertising forms targeted on websites that […]
Research on nematodes have always been convenient for scientists. For one, they grow and breed really fast, making them ideal for work pertaining to genetics. Some of them have amazing properties, like the planaria or “flatworm”, which some scientists believe it possesses the indefinite ability to regenerate its cells and thus practically never grow old. It […]
The reason why some drugs can only be taken by injecting them, instead of less intrusive solutions like oral ingestion, is because otherwise these drugs can not reach the bloodstream effectively. For people suffering from chronic diseases that require a lifetime treatment of drugs administered by injection, like those suffering from diabetes who need an […]
What if the world’s greatest unsolved heists were made by aviary burglars? Bear with me for a second. A bird is small enough to fit through cages and window cracks, it can fly in and out fast and on the sly, and if it ever gets caught, it won’t turn its partners in crime since […]
A number of human-like unique limb features, like the thumb, can be witnessed from the earliest most stages of development. Intuition tells us that this means the genetic changes and material that underlie these traits are active in the embryo stage. Recently, researchers Yale School of Medicine found there are thousands of active sequences that control […]
It’s rather ironic how in developed countries, despite an ever better quality of life, giving birth and raising a child becomes ever more difficult. Sure, people earn more, they’re more career orientated and growing responsibilities, or lack of responsibility for that matter, has transitioned parenting from early-twenties just a few decades ago, into early-thirties. It’s […]
It may surprise you to know that a life-threatening disability after complete spinal cord injury is urinary dysfunction – although numerous strategies and treatments have been tried, in the attempt of regrowing the severed axons, their success has been very limited. Now, researchers have finally come up with a solution that works, at least in […]
It’s rather clear that social-economic factors have a huge part to play in the development of an individual, but when discussing this we typically refer to education, something that can be more or less manipulated at any time, albeit with various degrees of difficulty. How do social-economic aspects affect the brain, though? Martha Farah, the founding director […]
Mammals can naturally regenerate the very top of their fingers and toes after amputation; starting from this idea, researchers have demonstrated the mechanism that describes this process, and explain how stem cells from nails could play a pivotal role in future regeneration of entire fingers. A study conducted on mice showed that the chemical signal […]
Located in the North Atlantic, right in between Greenland and Scotland, Faroe Islands is one of the smallest countries in the world. At the same time, however, it has also remained fairly isolated for many centuries, which in time has led to the formation of a distinct language and population. You can spot a native […]
Leprosy, or Hansen’s disease (HD), is a chronic infection caused by the bacteria Mycobacterium leprae and Mycobacterium lepromatosis. It was quite a common disease in Europe until the 16th century. Now, researchers have extracted DNA from skeletons that were 1,000 years old, analyzing the disease genetic code and comparing it to that of new strains, […]
Hours and hours spent at computers or gaming consoles do have their advantages – not only do they train reaction times and adaptation, but they also train the brain to make better and faster use of visual input, according to Duke University researchers. “Gamers see the world differently,” said Greg Appelbaum, an assistant professor of […]
A new study conducted by researchers from Ohio University concluded that both men and women will lie about their behavior to match cultural expectations. Well now, this is a new one – who would have thought people actually lie to have sex? But it gets even better – they used student behavior for this study. […]
It seems to me that we’ve just began to scratch the surface of what we know about autistic spectrum disorder (ASD). It’s been recently shown that autism is linked with child prodigies and that for some reason, autism rates continue to increase, especially in male population. Now, according to researchers at Vanderbilt University and the […]
For more and more people, ageing and clumsiness seem to go hand in hand – difficulties when handling a plate, fumbling with keys or even dialing a phone – new research from Washington University in St. Louis suggests that some of these day-to-day reaching-and-grasping difficulties may be be caused by changes in the mental frame […]
Mind-controlled devices, also known as brain-computer interfaces, have evolved a lot in the past few years alone, offering countless people who are paralyzed or missing limbs the chance of living a normal life. Non-afflicted individuals may profit from brain-computer interfaces as well, either for fun (why bother with gamepads or even Kinect when you can […]
As reported earlier on ZME, as little as three thousand tigers are currently alive today in the wild from six subspecies, or thirty times fewer than 100 years ago. Loss of habitat and poaching are the main drivers that brought these majestic cats at the brink of extinction. Now, a new threat might put tigers […]
In the aftermath of heavy rains from Tropical Storms Debby and Andrea, a giant mosquito species has surfaced and invaded central Florida. Authorities have issued warnings to residents to be extra careful of these very aggressive bloodsuckers that can grow up to 20 times the size of a typical mosquito. Their bite isn’t a lot more […]
A long-time assumption in the medical world is that mature, differentiated neurons do not divide and that they’re formed during the embryonic development stage. This does not necessarily mean, however, that all neurons are grown during this stage only and that they do not form during adulthood as well. Proving that neurons can form during adulthood […]
Our general appearance and dominating facial features have come a long way since the days of our early homo sapiens ancestors some hundreds of thousands of years ago. For instance the size of our brain, and of course skull that houses it, has grown in size three times since then. Moreover, medical records only a […]
It’s not a well known problem by most, but those who work in the field are very aware of it – medical isotopes are a very valuable commodity. But now, a Canadian team may have very well found a way to end the shortage, developing and upgrade that allows hospital cyclotrons to make a much-needed […]
Multiple Sclerosis (MS) is one mean, hard, disease. It’s an autoimmune disease – your body basically fails to identify itself, and starts attacking itself, and treatment is very difficult. In MS, the immune system attacks and destroys myelin, the insulating layer that forms around nerves in the spinal cord, brain and optic nerve. When the […]
It’s a staple of classic science fiction – controlling stuff with your mind. But researchers working at the University of Minnesota made it reality. From sci-fi to the lab In the lab of biomedical engineering professor Bin He, several people have already learned to use their thoughts to drive a flying robot around – making […]
Psychologists closely studying chimpanzee, bonobo and human infants found striking similarities among the three species in terms of different types of gestures. Their findings seem to back-up the theory that claims language, as we know it, evolved from gesture-based communication first. Panpanzee, a female chimpanzee (Pan troglodytes), and Panbanisha, a female bonobo (Pan paniscus) were […]
The case of birds missing out on a proper penis has been a longstanding mystery in evolutionary biology. Roughly 97% of avian species sport little or nothing like a real phallus, yet they still reproduce via internal fertilization. A new study, conducted by Martin Cohn, a developmental biologist at the University of Florida in Gainesville […]
A new study suggests that U.S. businesses pay almost $6,000 per year extra for each employee who smokes, compared to an employee which doesn’t smoke. Researchers claim this is the first study to focus on the cost of employing smokers vs non-smokers. So why does this happen? By drawing data from previous researches, focusing on […]
Yoga supporters have long claimed the benefits of the practice, both on the mind and the soul, but many skeptics underlined the lack of scientific studies in the field. Now, a team from Illinois University have shown that even a singulary, 20 minute session of Hatha yoga significantly improved participants’ speed and accuracy on tests […]
Scientists at the Rehabilitation Institute of Chicago (RIC) demonstrated a type of peripheral interface called targeted muscle re-innervation (TMR), part of DARPA’s Reliable Neural-Interface Technology (RE-NET) research program which seeks to develop effective brain interfaces. The prosthetic is simply amazing, as one can see in the video below featuring former Army Staff Sgt. Glen Lehman, injured in Iraq. The […]
It’s not quite what scientists expected – the width of blood vessels in the eye, at the back of the retina, may indicate brain health risks, such as dementia and alzheimers years before they actually set in according to a new study published in Psychological Science. It is already well known that young people who […]
One big obstacle scientists face in their efforts to develop effective drugs against HIV is the virus’ capsid – an outer cell membrane-derived envelope and an inner viral protein shell that protects HIV essential proteins and genetic information. Current drugs have a hard time breaching this structure, however this might change. Using a supercomputer that crunched immense […]
We’ve written a great deal about schizophrenia in the past, mostly reports about new theories pertaining to the development of the disease or new types of pharmacological treatments. A great deal of interest and efforts are being invested in battling this severe psychological disorder, since it affects so many people (as many as 1 in […]
Babies learn to babble before they can talk, usually starting with the “ba-ba”, or “ga-ga”, or in the really fortunate cases – with “ma-ma”. After that, they start stringing a few random syllables together, and only after that, they actually start talking. Songbirds exhibit the same type of behavior when they start singing, and the […]
