A US Army laboratory in Utah accidentally shipped live samples of anthrax, prompting immediate efforts to recover the samples and make sure that no one suffers. In total, 26 people have been put in post-exposure treatment, a defense official said.
Clostridium difficile is a bacterium that can cause numerous medical problems, including colitis or colon inflammation; in severe cases, it can actually be fatal. Now, doctors have tried a new approach in dealing with it - they tried not to eliminate it, but to replace it with its friendlier cousins.
Drug-resistant bacteria are one of the biggest challenges mankind has to face in the near, as well as distant, future. In a recent survey conducted by the World Health Organization it was revealed that only 34 out of 133 questioned countries have even a basic plan to combat the misuse of antibiotics fuelling drug resistance and encouraging the development of superbugs.
The National Health and Medical Research Council (NHMRC), Australia's top medical research body, found that homeopathy does improve or alleviate any medical condition after systematically studying 225 research papers on homeopathy. While it's true some people might feel better after a so-called homeopathic treatment, the researchers conclude that these benefits are no better than ingesting a sugar pill - a placebo.
Sick, got the flu? Well, maybe what you think is the flu really isn't the flu... a new study has found that while children catch a flu once every two years on average, the rate goes down significantly in adults - the average adult only gets it once every 5 years.
A while ago I wrote that the applications for graphene are endless, and it seems like scientists just want to make prove me right - University of Manchester scientists have used graphene to target and neutralise cancer stem cells while leaving healthy cells unharmed.
It's always the cute ones - a team of Norwegian researchers found that the Black Plague, which arrived in Europe in the 14th century and wiped out up to 200 million people was brought by gerbils, not by rats.
In 2000, the American Academy of Pediatrics advised parents to keep children as far away from peanuts as possible, in order to avoid potential allergies - it seemed like a good idea at the time. But now, a new study has found that in the long run, that actually did more harm than good, and if we want to fight allergies, we should be feeding our children peanuts.
Almost 70% of HIV-infected people in the US are either undiagnosed or not receiving care; this population is responsible for 91.5 percent of all infections, according to the CDC.
The ability to keep malaria under control is crucial - the disease is highly contagious and the potential health hazards are immense. Efforts have been somewhat successful, with fatalities dropping from over 1 million in 2000 to 584,000 in 2014. But the protozoans that are causing the disease are starting to become immune to the drugs we are using, and that's a huge problem.
A new study has found that as the climate continues to warm, we will be dealing with more infectious and parasitic diseases. Ultimately, we'll have to face epidemics caused by climate change, researchers say.
For the first time, scientists have developed a treatment for Multiple Sclerosis (MS) that actually reverses the disability. Dr. Richard K. Burt performed the first hematopoietic stem cell transplant (HSCT) for a multiple sclerosis (MS) patient in the United States at Chicago’s Northwestern Memorial Hospital, and the treatment shows great promise.
A lot of Americans seem to be confused about what are antibiotics and what they're good for. According to a YouGov survey (full results), a third of American correspondents replied that antibiotics can cure the flu, while a third also thought that vaccines can give you the flu. It goes without saying that this is false. The findings suggest an over prevalence of thought that antibiotics are "good for everything", an abuse that might cost public health dearly.
The World Health Organization reports a drop in the Ebola cases in the three Western African countries hit most by the disease. However, as farmers abandon their fields in the infected areas, a new problem seems to emerge: a food crisis. Liberia only reported 48 cases in the past three weeks, but Sierra Leone is still struggling, with […]
The WHO says that the government's lack of action is adding much to shape the Ebola epidemic ravaging through West Africa and threatening the entire planet. The situation became more serious, and the WHO has released a document asking for more action if we want to control this epidemic and future ones.
When the flu hits, an unmistakable feeling of drowsiness sinks in. Washington State University Spokane scientists have now found a specific protein that is uniquely involved in sleep responses triggered by the influenza virus in mice. They found that the protein boosts the healing power of sleep and helps recovery. The researchers speculate that it might be possible to develop treatments based on it that might speed up recovery even more.
The "one size fits all" approach to diabetics treatment may cause significant problems for older patients also suffering from other conditions. Attempting to aggressively control blood sugar with insulin and sulfonylurea drugs could lead to over-treatment and hypoglycemia (low blood sugar), Yale researchers report.
A new study has shown that people with optimistic views of life tend to have much healthier hearts and have much lower risks of cardiovascular disease.
As modern medicine can be quite paradoxical sometimes, checking into a hospital can actually boost your chances of an infection; and if you’re thinking that this only happens in poorer, underdeveloped countries – you’re wrong. No matter where you check in at a hospital, you are vulnerable to infections which have nothing to do with […]
Malaria is one of the most common and dangerous diseases in the world, with the World Health Organization estimating over 200 million cases every year. There are several ways to try to treat malaria, but the results are debatable and often times not as effective as desired. Now, a team has demonstrated a new compound […]
You often hear people complaining that kids don’t play outside anymore – instead just hanging in the house all day long, playing on the computer (tablet/xbox/whatever). This is a pretty big problem, because there is a myriad of advantages to playing outside; this study has added yet another advantage to that list: playing outside reduces […]
There is currently no Lyme borreliosis vaccine available for humans available for purchase, but a new research has shown how such a vaccine could be made. Lyme disease (Lyme borreliosis) is an infectious disease caused by at least three species of bacteria belonging to the genus Borrelia. Each year, approximately 30,000 cases of Lyme disease are […]
If you thought the bubonic plague is a thing of the past… then think again! The dreadful disease is making a resurgence in the island of Madagascar, off the eastern coast of Africa. There have already been 138 suspected cases of the disease, with a total of 47 victims. You may know the black plague as […]
The Nanoflare technology uses a genetic-based approach to detect and image live cancer cells present in the blood stream, well before these had a chance to develop into a tumor. The gene-hunting particles developed at Northwestern University might help doctors develop personalized treatments for their patients and curb cancer spread, according to the paper published […]
Scientists have found a way to prevent cancerous tumors in the prostate from spreading, effectively switching off the disease. Researchers from Bristol and Nottingham universities found that a single molecule plays a crucial role in the forming of new blood vessels, and the spread of tumors could be halted with a mere injection. A neoplasm (commonly […]
Diabetes is one of the most prevalent diseases in the developed world, with more than 29 million infected Americans; 1 in 4 doesn’t know. Currently more than 29 million people in the United States have diabetes, up from the previous estimate of 26 million in 2010, according to a report released by the Centers for […]
An initial study has shown that a vaccine against Hep C currently in clinical trials is effective and also safe in humans. Hepatitis C is an infectious disease affecting primarily the liver, caused by the hepatitis C virus (HCV). There are some 200 million people in the world infected with the disease, and around 75-85% of […]
Vaccination has been highly successful in reducing the prevalence of poliomyelitis. Routine vaccination has helped reduce the number of cases by more than 99% in 30 years. However, epidemics are still occurring, and we’re still miles away from eradicating the virus. Researchers have now identified the exact strain responsible for recent outbreaks and showed that the mutations […]
French scientists described the mechanism through which two HIV-infected individuals have become “spontaneously cured” of the virus, explaining that this can lead to new, novel treatments in the fight against AIDS. The “apparent spontaneous cure” has opened up previously closed doors for drug engineers, they note. “The work opens up therapeutic avenues for a cure, using […]
In 2003, Dr. Lihong V. Wang at Washington University introduced one of the most exciting technologies we’ve had the chance to see in a long while. By combining ultrasound and light absorption, Wang and colleagues developed a new method that makes multicontrast images of biological tissues several inches below the skin. Among others, this allows specialists to see […]
On Tuesday, Google’s head of life sciences inside the company’s Google X research lab reported a new exciting project that involves using nanoparticles that magnetically attach to key molecules and cells in the bloodstream to detect diseases, including cancer. The particles – ingested under the form of a pill – would later be gathered, scanned and […]
According to a study from Women’s College Hospital and the Institute for Clinical Evaluative Sciences (ICES), Canada, it doesn’t matter whether you live in a rural or urban setting when it comes to heart disease – the risk if the same for both environments. The general consensus is that those living in rural areas are […]
A permanent vaccine for hookworm has passed clinical trials. The hookworm is one of the most pervasive parasites, affecting over 600 million people worldwide. The virus is also known for affecting mostly poor populations. The hookworm is a parasitic nematode (roundworm) that lives in the small intestine of its host, which may be a mammal […]
Scientists have resurrected a 700 year old virus form Canadian permafrost and showed that even after several centuries of lumbering, viruses can remain… well. virulent. This could have significant implications, because as global warming continues melt more and more permafrost, unknown viruses could be released into the environment – and there’s currently no way of telling […]
Yoshihiro Kawaoka has caused massive uproar in the scientific community when he announced he is attempting to recreate the world’s most lethal virus. Biologists are polarized on the issue, with some claiming that it is reckless, while others approving that it will help us better understand pandemics and how we can protect ourselves against them. […]
An innovative research posits that cancer may actually be a sort of 'safe mode' mechanism, akin to how a computer's operating system reverts back to safe settings to preserve itself, which evolved shortly following the first single celled organisms. The research was made by an unlikely team of scientists: an oncologist, an astrobiologist and a cosmologist. If the findings are right, then cancer may be fought off more effectively using oxygen treatments and infection with viral or bacterial agents.
The heart regularly speeds up or down its beating frequency to adjust to the body’s needs. Even in stable conditions (when you’re not particularly active or your active for a constant time), the amount of time between heart beats is variable. A team of doctors and engineers at Caltech’s Division of Engineering and Applied Science have now found […]
In many cases, doctors prescribe antibiotics to children, but most of the time, those viruses don’t even respond to antibiotics, a study finds. When you have a cold, or a headache, there’s a good chance you might just shrug it off, or fight it with an aspirin or some Tylenol – but if your child is […]
We might be dealing with the worst Ebola outbreak in history – even though no one would have predicted this a few years ago. Hastened by the urgency of the matter, a trial of an experimental vaccine against the Ebola virus is to begin in Oxford. Normally, it would take another couple of years of testing […]
As microbes become more and more resistant to antibiotics and cleaning products, it’s crucial that we find better, more efficient way of fending them off. Dr. Samir Mitragotri from the University of California at Santa Barbara has led a team which showed that ionic liquids (ILs), also known as liquid salts, dramatically improve the treatment of microbial […]
Stanford Professor of Bioengineering and Applied Physics, Stephen Quake, and Head of the Ophthalmic Science and Engineering Lab at Bar Ilan University Dr. Yossi Mandell teamed up and created a new device which allows glaucoma patients to continuously monitor pressure levels in their eyes – this provides not only a better monitoring, but it also […]
Occasionally we’re hit by fever. Nobody likes it, most sane people actually hate it, but it’s important to note that it’s an important part of the healing process. Fever is a result of the immune response by your body to foreign invaders like viruses, bacteria, fungi, drugs, or other toxins. Research showed that it is triggered […]
Patients with hemophilia are often forced to live in a bubble. Even the smallest cut can cause significant blood loss, and often times these minor accidents can also cause internal bleeding that affects organs and threatens life. Some treatments have proven effective at keeping hemophilia at bay, at least to a degree, yet some groups […]
Scientists were surprised when they unexpectedly stumbled upon a relatively simple vaccine which blocks infection with SIV – the monkey equivalent of HIV – and stops the spread of the virus in already infected monkeys. How it works All efficient vaccines against a viral infection elicit virus-specific neutralizing antibodies and sometimes also cytotoxic T-lymphocytes (CTL) […]
A medicine administered even up to 3 days after infection can save monkeys from the Marburg virus – an incredibly dangerous pathogen closely related to Ebola. “This clearly starts to move into the realm of being a therapy, rather than a post-exposure treatment,” says virologist Gene Olinger, principal science adviser for contract-research organization MRIGlobal in […]
Ebola is starting to get more and more worrying. Now, a team of WHO researchers has announced that the outbreak may have been underestimating, as it spreads much faster and affects more people than previously thought.
As reported earlier, 2014 has seen the worst Ebola outbursts in history. Recent escalations of the outbreaks and spread to other countries like Nigeria has finally prompted the World Health Organization (WHO) to declare the Ebola situation a Public Health Emergency of International Concern (PHEIC). The report is meant to raise more awareness to the deadly threats […]
The shutdown of a key protein allows grizzly bears to go through tremendous weight gains without loosing insulin sensitivity. Thus they're never at risk of getting diabetes. What if we could shut this protein down for humans too?
The new study concludes that an aspirin a day for middle-aged people could save 130,000 lives over 20 years in Britain alone, by reducing cancer risk. Aspirin was most effective in cutting cancer risk in people from 50 to 64, and in order for the effects to be felt to the fullest, people should take 1 […]
Researchers have found a cheap and quick way of producing peptides in a laboratory. Producing one of the body's natural defenses against cancer and then implanting it into patients can prove pivotal in the fight against cancer.
