The beginning of autumn brings cold weather, and with it, another type of flu. We here at ZME have already all gone down with a bad case of the flu, and of course, we’re not nearly the only ones. Each year seems to bring the threat of a new flu virus; first it was the […]
Nauclea latifolia (also know as the pin cushion tree) is a small shrub, relatively common, used in traditional medicine throughout the sub-Saharan regions. Of course, African traditional medicine is not often your first choice when it comes to a treatment, but what if I told you that this plant produces large quantities of molecules – […]
A new study made by researchers at Washington University School of Medicine in St. Louis and Harvard Medical School found that girls ages 9 to 15 who regularly ate peanut butter or nuts were 39 percent less likely to develop benign breast disease by age 30. Benign breast disease, although noncancerous, increases risk of breast cancer later in […]
A first step has been taken towards an effective treatment for Gonorrhea – with drug resistant strains on the rise, this moment comes just at the right time, merely days after the U.S. Centers for Disease Control (CDC) placed the STD on a list of “urgent threats” in the fight against drug-resistant bacteria. Gonorrhea (colloquially […]
Closed chest defribillators (the type of defribillators you see on TV) have been around for decades, and for a good reason – because they get the job done. They’re very effective at restoring normal heart rhythm, but they have a big disadvantage: even with fine tuning of modern devices, they hurt like hell. Researchers now […]
The X-Shape in which we usually see chromosomes depicted in is only a snapshot of their real complexity – a new method for visualizing them showed. A joint project involving the Babraham Institute, the University of Cambridge and the Weizmann Institute has produced the most beautiful and accurate models of chromosomes available up to date. […]
A man from China has had a new nose grown on his head by plastic surgeons, as part of a surprisingly common reconstruction technique. The 22 year-old suffered nasal trauma after a car accident, and the following infection eroded the cartilage in his nose, making it impossible for doctors to fix it. Instead, the team […]
Coma patients, be it inflicted from trauma or initiated by doctors to preserve bodily functions, have their brain activity regularly monitored using electroencephalography (EEG). When in a deep coma the brain activity is described by a flat-pattern signal- basically minimal to no response, one of the limits that nearly prompts establishing brain death. A group […]
“My initial interest was an artistic one at heart, but, surprisingly, we could instantly differentiate seizure activity from non-seizure states with just our ears,” Chafe said. “It was like turning a radio dial from a static-filled station to a clear one.” When Chris Chafe and Josef Parvizi from Stanford University began transforming recordings of brain […]
It may not seem like it, but the influenza (flu) virus is one of the most dangerous in the world due to the speed with which it evolves – each year, several new strains appear, making existing vaccines (and sometimes treatments) obsolete. The bird and swine influenza are just two examples of recent outbursts caused […]
Humans and other mammals show particularly intensive sleeping patterns during puberty – this is also the period during which the brain matures the most; but when pubescent lab rats were administered coffee, their brains matured much slower and not so efficient, a new study shows; considering that children’s and young adults’ coffee consumption has increased […]
Among the criticism that wind energy gets, one main idea some people complain about is that wind turbines are noisy; some people have even went as far as to claim that even though most of the created noise is way below the range of human hearing (infrasounds), it can cause health problems, including heart issues […]
A Harvard longitudinal study that looked at 734,889 people who were diagnosed with cancer between 2004 and 2008 found that married patients were more likely to recover that those that weren’t. The findings don’t particularly suggest that the emotional support itself helps with the healing, but rather the attention offered by the spouse typically prompts patients […]
For some 50 years, scientists have tried — but failed — to find a way to use microbes against termites. What makes these magnificent creatures (which are often destructive for humans, and even regarded as pests) so resistant in the face of very dangerous microbes – designed specifically to kill them? University of Florida researchers […]
Some people are born with the innate ability, or better said disability, of not feeling pain – whatsoever. It’s not that they can’t feel anything, quite on the contrary – they still have a sense of texture, they feel pressure, they can feel a hug or handshake just like anyone, they experience warmth or coldness […]
Counter the popular dictum “out of sight, out of mind”, Kerri Boutelle, professor of psychiatry and pediatrics at University of California, San Diego’s School of Medicine, wants to tackle junk food addition in a novel way. In her experiments, she instructs overweight kids to stare at foods like french fires or cheetos in order to overcome their […]
For the first time in history, scientists from the Florida campus of The Scripps Research Institute (TSRI) have been able to eliminate dangerous drug-associated memories in mice and rats without apparently affecting other memories. Erasing memories If you’ve ever seen The Eternal Sunshine of the Spotless Mind (truly a remarkable movie, which I highly recommend) […]
It may come as a shock to you to find out that the chemical make-up of human urine hasn’t been identified until now – but it shouldn’t. The study which led to this breakthrough took over seven years and involved 20 researchers; in the end, it revealed over 3.000 metabolites (small molecules resulted through […]
A cross-disciplinary team of scientists at Harvard that developed a novel type of vaccine for treating melanoma – the most lethal form of skin cance – recently announced the vaccine will enter its Phase 1 clinical trial. The announcement comes just a few years after the vaccine was tested on mice, 50% of whom showed […]
In a preclinical study recently published by the journal Organic & Biomolecular Chemistry, researchers combined structural features from anti-nausea drug thalidomide with common kitchen spice turmeric to create hybrid molecules which are very effective at destroying multiple myeloma cells. Thalidomide was released into the market in 1957 in West Germany and was typically prescribed as […]
Henry Ford’s Model T automobile changed not only the way the average American traveled (the first trully affordable vehicle for the middle class), but the way industry in all its forms viewed production. By switching from hand craft to the assembly line, Ford drastically cut cost and speed of production of his automobiles, a model […]
It’s amazing how two different animals from two completely different environments evolve some identical physical features. Take bats and dolphins for instance. Both of them use a complex system that produces, receives and process ultrasonic sound waves in order to identify visually hidden objects, track down prey or navigate through obstacles better – typically this […]
The fat-tailed dwarf lemur, native to the marvelous isolated ecosystem of Madagascar, is the closest human relative known to hibernate. After studying the sleeping behavior of both captive and wild lemur specimens, scientists at Duke University have discovered a great deal about how hibernation works in lemurs. The key discovery is that they can go […]
In one of Stanley Kubrick’s weirdest movies (even by Kubrick standards), “Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964)“, one of the characters played by Peter Sellers is tormented by the irresistible and convulsive urge of lifting his right arm in a Nazi salute. He can’t control it, it’s […]
Today, cancer is typically treated through highly invasive, painful and low efficiency treatments. Doctors resect the tumors, do radiation therapy, and then chemotherapy. This process is actually more stressful and painful to the patient than the cancer itself, but it does save lives sometimes. Scientists all over the world are hard at work developing alternative […]
A team of evolutionary biologists at Indiana University has shown for the first time that asexual lineages of a species are doomed not necessarily from a long, slow accumulation of new mutations, but rather from fast gene conversions which unmask preexisting genetic mutations. The groundbreaking research started with the sequencing of the entire genomes of […]
Every time we’re engaged in a certain action, the sounds we produce while walking, eating, even playing music are tuned down a notch in volume by the brain. For instance, during a conversation your voice will be perceived as quieter than it actually is in reality, since our brain want to receive clearer the information […]
One of the smallest amphibians in the world, the Gardiner’s Seychelles frog, is also one of the most eccentric. The frog doesn’t stand out through an over-glamorous coloring or some unique, wild mating call, but rather as a result of one of its weird biological features. This frog doesn’t have ears – yet it can hear. […]
For infertile women everywhere, regardless of age, health and status, one thing was sure – they were never going to have children; and I say ‘were’ because now we have a precedent, a way through which that can be changed: an infertile Australian woman is now pregnant after growing new eggs in ovarian tissue transplanted […]
Snoring is a universal problem that affects a huge chunk of the population around the world. It doesn’t matter how rich you are, how smart you are, if you snore – you snore. There are various causes for snoring. As is the case with the other common conditions that affect a large number of people […]
A new study that surveyed through records of hundreds of thousands of men from 15 European countries found that the average height has risen by 11 centimeters since then 1870s. This remarkable surge in men’s height over the span of just four generations has been attributed to the advances in health care since, most notably […]
For some reason which continues to elude me, people are eating less and less fruit – but perhaps the increasing consumption of juice has something to do with this. Now, a new study led by Harvard School of Public Health researchers has shown that eating more fruits, particularly blueberries, grapes, and apples, was associated with […]
Pollution is real, and it’s a global phenomenon; it doesn’t happen only in the Captain Planet cartoons, and it’s not restricted to Africa or China. Sobering data from MIT’s Laboratory for Aviation and the Environment has shown that air pollution is having a dramatic impact on American health: over 200.000 lives are claimed early because […]
Fatal overdoses due to painkillers have reached epidemic levels, greatly exceeding those from heroin and cocaine combined, becoming the worst drug epidemic in US history. Prescriptions for painkillers in the United States have nearly tripled in the past two decades, and the results are dreadful. In 2012, enough painkillers were prescribed to keep every single […]
Most medical research looking to identify the mechanisms of a disease or test treatments rely on animal models. While very useful, mice for instance (a favorite lab pet for researchers) do not have nearly the same brain structure or genes as humans. Even if some genes and proteins scientists target are the same both in […]
Scientists have discovered an atypical gene that is thought to be crucial for the generation of new neurons in the brain, a process called neurogenesis. The discovery and further study of the gene might help scientists better understand how neurodegenerative diseases such as Alzheimer’s affect the brain and, in term, how to address them. New […]
In a mind-boggling and, frankly, a bit frightening breakthrough, researchers at University of Washington have devised a brain-to-brain interface that for the first time has allowed the remote exchange of information between two human brains. The test that demonstrated the technology, although simple in nature, shows of a powerful display of force. One researcher (human brain […]
Crows, like most other species from the corvid family (ravens, rooks, etc.), are some of the most intelligent animals on the planet, actually rivaling apes and dolphins. Tool use is common among these birds, but where they shine is in their social and emotional intelligence. For instance, a few years ago I reported how ravens point […]
For nearly two years now, Syria has been embroiled in a gruesome civil war that has so far claimed thousands of lives. Cruelties in the region reached a climax in past weeks after alleged reports of chemical weapons use against civilians were made. So far, it’s unclear which side – the government or rebelling opposition […]
Regenerative medicine has come a long way, and while important strides forward have been made, scientists are still toiling with ways to completely grow organs in labs. There are millions of people worldwide suffering from afflictions to organs like the liver, lungs or heart – for many of them a transplant is they’re only chance […]
It’s clear that humans are now, more than ever, a driving force in evolutionary biology. Early domestication efforts through breeding and training have changed some species to the point that they’ve grown to be as we wanted them to become. The effects of climate change, a great part of which is anthropogenic, actually influence animals […]
Many months later after scientists isolated thousands of samples taken from different bat species found close to the home of the first known victim of the Mers coronavirus – a deadly virus which first emerged in the Middle East last year, killing 47 so far (~50% fatality among infected) – scientists found the evidence of the […]
There’s an extremely fine line between delusion and grand vision – it’s enough just to take a look back in history and you’ll find a myriad of examples where great minds who justly challenged the status quo were labeled insane, and in some even more unfortunate times, heretics. That’s not to say that behind every […]
Researchers at the Norwegian University of Science and Technology’s (NTNU) Department of Neuroscience analyzed a massive survey of 130,000 randomly chosen people from the US to see whether there is any association between psychedelic drug use and mental health problems – a claim that has had large circulation and is often cited, despite little research in […]
Our bodies are hosts to some hundreds of thousands of bacteria that live in harmony with each other, helping the body be healthy, in return for the food and shelter it provides to these tiny organisms . Collectively, all the microorganisms inside the human body are referred to as the microbiome, most of whom are […]
It has been previously shown that during ovulation, women tend to increase their attractiveness to men (though not necessarily conscious). Not only do they change their voice pitch [1], but they also tend to dress more fashionable [2]. A new study published in Psychological Science adds to this growing body of research by suggesting that […]
Some 300 million cases of malaria are reported each year in Africa, the continent where the disease is still running rampant. For decades, scientists have been investing immense amounts of energy battling the disease, trying to come up with effective treatments. The recent step forward in the war against malaria comes from Maryland-based biotech Sanaria, which […]
Dr. Sanjay Gupta is an established neurosurgeon, but you all might know him better as CNN’s chief medical correspondent through the various live interventions he’s had along the years on television as well as some feature documentaries. Last night, his most recent documentary, called “WEED”, premiered on CNN as you might have already guessed, it’s all […]
The Argus II is the first bionic eye implant, designed to grant the blind vision, that has been approved by the FDA in the US. The wearer of such an implant is now capable of distinguishing objects and live an almost independent life, which is absolutely remarkable by itself, however its performance is light years […]
A while ago, ZME Science reported on some mind blowing research in which dogs were trained to literally sniff lung and breast cancer from samples. The dog’s detection accuracy was between 90% and 95% for breast and lung cancer, respectively, compared to biopsy results. Recently, a collaborative team of researchers from University of Liverpool and the […]
