Ian Lipkin, a virus hunter from Columbia University, along with fellow professors Thomas Briese and Amit Kapoor have designed a new system, known as VirCapSeq-VERT, that they claim can detect any known human virus in a blood sample.
Developed by Transmedics, the OCS Heart, often referred to as the “heart in a box,” is a machine that keeps a heart supplied with blood and oxygen for several hours. This allows it to be moved to another patient for transplant. Heart transplants aren’t exactly a new thing—the first one was performed in 1967—but the organ is usually kept on ice while being moved. So why bother keeping a heart beating at all? What does this device do that ice can’t? As it turns out, quite a bit.
A team working at the Francis Crick Institute in London applied to the Human Fertilisation and Embryology Authority for a permit that would allow them to edit genes in a human embryo. If allowed, this would lead to the very first genetically modified embryo in the UK. The scientists claim they need approval to do basic research that may " improve embryo development after in vitro fertilization (IVF) and might provide better clinical treatments for infertility,” and not for clinical research. Either way, the controversial practice is banned in all Western countries and virtually banned, although not explicitly, in the US.
A video of an ape, breaking out of its cage and attacking; the victim -- a human scientist, that picks up a small red hammer and defends himself, battering the primate ran amok. It sounds like a pretty gruesome video, bound to have animal right's activists redouble their efforts to see the heartless jailers brought to justice. But hey, wait a minute... Apes don't wear sneakers.
A dubious pharmaceutical startup recently bought the rights to a drug that treats a parasitic infection, then raised the price 500-fold seemingly over night. The drug targets a somewhat rare condition that affects immune compromised pregnant women, but also malaria and AIDS. Ironically enough, it was developed by a much hated big pharma company, GlaxoSmithKline, in 1953 and used to cost $1 a pill only a couple years ago. It has since traded hands twice, before coming under the control of Turing Pharmaceuticals, a start-up run by a former hedge fund manager.
Fourteen years ago, a leading drug maker conducted a study which concluded that Paxil, an antidepressant, was effective and safe for teenagers. But now, a major medical journal published an analysis concluded the opposite.
Regular soap is really good at killing bacteria, but most people feel that antibacterial soaps are even better. After all, they're antibacterial, right? Well, according to a thorough research, that's not true at all - regular soap works just as good as antibacterial soap.
A research team has demonstrated the effectiveness of a 3-antibiotic cocktail that kills methicillin-resistant Staphylococcus aureus, or MRSA, in all mice that were treated with it.
The most detail study of its kind found air pollution is responsible 3.3 million premature deaths. Based on current trends of agricultural and industrial expansion, the study projects 6.6 million will succumb to soot and smog in 2050, or double today's death toll. Most of these fatalities will be registered in developing nations like India, Pakistan and China.
New research has found evidence of emotional burden sharing (also known as load sharing) between partners in a close relationship. The study, co-authored by Queen's University PhD candidate Jessica Lougheed, found that a strong personal relationship can help ease stress when placed in difficult situations.
By 'tickling' select membrane channels you can effectively control neurons, by activating or deactivating cells. You can do this using electrical currents, like we see very well illustrated in brain-computer interfaces; light (the field of optogenetics); and sound (sonogenetics). Yes, sound. This was only recently demonstrated by researchers at Salk's Molecular Neurobiology Laboratory who used ultrasounds to control neurons in the nematode Caenorhabditis elegans.
Scientists have genetically modified yeast to produce the main psychoactive substance in marijuana, THC. Responsible for most of weed's effects (including the high), THC can also be used for medical purposes, to treat symptoms of HIV infection and chemotherapy.
Reconstructive surgery just got an upgrade after a patient who had lost four ribs and part of his sternum had a 3-D printed titanium replica fitted instead. This was the first such procedure. Although the operation was a sound success with the replica matching like a glove, doctors say that this sort of intervention is only for really extreme cases. You can't become Wolverine overnight, not exactly at least.
A 28-year old who has been paralyzed for more than a decade following a spinal cord injury has become the first person to be able to “feel” physical sensations, through a special prosthetic developed by DARPA – the Defense Advanced Research Projects Agency, a US agency responsible for the development of emerging technologies, mostly for military purposes. The […]
Leafcutter ants in South America grow fungus as crops, this has been known for quite a while. But their crops show clear signs of domestication, which means that when it comes to farming, the ants might have beaten us by some 50 million years. Ant farmers When people started growing crops, they unwittingly made changes […]
Humans are naturally lazy, as they'll always find a way to execute a movement, even a simple act like walking, with the least expenditure of energy. Our nervous system, it seems, is hot-hired to find the optimal energy balance for any movement. It's so good at it, that it adapts to a new gait or environment within a matter of minutes.
A French court upheld on Thursday a 2012 ruling in which Monsanto was found guilty of chemical poisoning of a French farmer who suffered from neurological problems after inhaling the U.S. company’s Lasso weedkiller. Alachlor is an herbicide, the second most widely used herbicide in the United States; it’s been banned in Europe since 2006, but in 2004, […]
A promising diagnosis test can accurately detect cancer in 7 out of 10 patients just by reading telltale genetic mutations found in the blood. While it will not replace invasive biopsies when the test runs negative, the procedure could help identify tumours earlier. When cancer is involved, the faster you find it, the better the chance of surviving it.
While analysing starch grains on ancient stone grinding tools from southern Italy, Marta Mariotti Lippi at the University of Florence in Italy and her colleagues were able to date the earliest known human consumption of oats as far back as 32,000 years ago – way before farming took root.
It's been only a decade since the Human Genome Project finished its task of mapping all the code that makes up our DNA. The hard part came later, though - identifying what each piece of code does or, oddly enough, does not. According to the most recent estimate for instance, only 8.2% of the code embedded in the human genome is actually useful, in the sense that it performs a function whether activating a gene, regulating it, and so on. The rest is what scientists class as "junk DNA".
There's no cure for Alzheimer's - the devastating neurodegenerative disease which causes progressive dementia in 5.3 million Americans - only treatments that help slow down a certain outcome. A milestone research may have finally broken the dry spell in Alzheimer's research looking for the much sought after cure. While current drugs help mask symptoms, a intravenous drug developed by US researchers actually treats the disease itself with patients showing marked improvements in memory and cognition. At the brain level, new blood vessel formation and an increase in neuronal cell counts was registered. The bad news is that the Alzheimer's patients are rats and experience has taught us that Alzheimer's research seldom translates to humans. Seldom, not never though.
A recent study performed by researchers working at the University of Oxford, Harvard Medical School and the University of Nevada suggests that the current school and university start times have a damaging effect on the learning and health of students.
The right music can evoke powerful emotions seemingly out of the blue, but under the influence of LSD the musical experience is enhanced even further. This according to the Beckley/Imperial Psychedelic Research Programme which tested this long held assumption under a modern placebo-controlled study for the very first time.
One of the planet's most endangered antelope, the saiga, suffered from a die-off of unprecedented scope. The massive loss of life from just a few weeks ago has conservationist groups worried about what future may hold for the species. But clues as to exactly what wiped out half of Kazakhstan's saiga are starting to emerge, and scientists are looking at bacteria that normally co-exist with the antelope host, harmlessly living in their bodies as the main culprit.
Americans' love affair with coffee has turned into an obsession. More than half report drinking coffee at least 3.1 cups each day, totaling a $40 billion market. For some, regular coffee isn't enough so they go for the extract: powdered caffeine. The drug is unregulated and can be sold over the counter in any pharmacy. You can even buy a one kilo bag (2.2 pounds) off Amazon and have it delivered to your doorstep. So, what's the problem? It's caffeine right? Well, to problem is that even a few teaspoons of the powdered caffeine mixed with a drink can potentially kill you. It's really, really easy to overdose and, case in point, two teenagers passed away last year in separate incidents. They had no idea what they were doing, and the confusing labeling might have had something do with it. Now, the FDA has officially sent warning letters to the biggest US producers of powdered caffeine that they should change their labeling in 15 days from the issued order.
A startling report by The Guardian reveals how the American Egg Board (AEB) - a government-backed board which gets a levy of 20 cents per case of eggs sold by its constituent members - lobbied against a food startup that's been gathering steam lately. Feeling threatened, AEB used its influence to put pressure on the FDA, USDA and Unilever to basically ruin Hampton Creek's business. Hampton Creek is a Silicon Valley startup which has so far gathered $120 million in funding. Its flagship products include eggs made out of plants and egg-less mayo, called Just Mayo which Joanne Ivy, president of the American Egg Board, refers to as “a crisis and major threat to the future of the egg product business.”
Doctors found that a British man has been excreting live polio virus for nearly 28 years, despite being vaccinated. These sort of cases aren't unique, but this is by far the longest cases seen thus far. Moreover, the immune deficiency has allowed the virus to mutate and replicate inside the man's body. Doctors say, however, that there are no health hazards involved since the man lives in a immunized community.
Is this our most obvious, useless headline yet? Might be, but don't hate the messenger. I'm just reiterating the findings of Canadian and Dutch researchers who performed two distinct studies to see what's the best relief against hangovers. Their conclusions are stark: there is no proven remedy against hangovers. If you want to avoid feeling like train wreck in the morning you should simply drink less.
For girls about to have their first period in rural India, menstruation can change their lives for the worst. Unable to afford disposable pads and tampons, girls often use rags which they reuse risking all sorts of health complications due to lack of sanitation. Many also decide to drop out of school out of fear that their rags might show or leak blood. “A fear of staining their clothes and being teased or humiliated about it by their male classmates seems to be a major reason of girls themselves choosing to miss their classes,” Maria Fernandez Ruiz de Larrinaga, communications specialist at UNICEF India says.
For the first time, aggressive breast, lung and bladder cancer have been neutralized and turned back to normal cells, prevented from excessive multiplication. Scientists at the Mayo Clinic in Florida, US, likened it to applying brakes to a speeding car.
The results of a new UEA study reveal that people who eat high levels of certain amino acids found in meat and plant-based protein have lower blood pressure and show less arterial stiffness, directly translating to higher levels of cardiovascular health. The magnitude of the association is similar to those previously reported for lifestyle risk factors including salt intake, physical activity, alcohol consumption and smoking.
Life expectancy has gone up by six years on average throughout the world since 1990, according to a survey led by scientists at the Institute of Health Metrics and Evaluation at the University of Washington. The extensive survey analyzed records from 188 countries. Japan tops the list with an average life expectancy of 83 years. While there's reason to rejoice in the news, it's worth mentioning that living with disabilities and illness has also been prolonged. The same advances that helped us live longer have also prolonged our suffering and this is where scientists are trying to invest their energy: focus less on extending life expectancy and more on the quality of our last years on this planet.
The trend is clear: medicine is becoming more and more personalized. Ultimately, when you'll enter a hospital for a diagnosis or treatment, a (likely digital) doctor will use tailored solutions to address your health needs, all based on your past medical and genetic records. Considering diagnosis, just a few drops of blood will be enough to diagnose a plethora of afflictions. Take the latest news coming from the The Institute of Cancer Research in London, for instace. There, British doctors were able accurately predict which breast cancer patient will relapse next by tracking key mutations of residual cancer cells found in the blood. It's a very powerful tool - one that will probably become standard practice soon.
If you’ve ever lived with someone hard of hearing, or have struggled with hearing difficulties yourself, you know it can be a hard condition to live with. Thankfully, modern technology has given us a wide variety of hearing implements that can let us salvage this precious physical sense. But hearing loss can come with several […]
Nanoengineers from the San Diego University of California used innovative, self-developed 3D printing methods to create multipurpose, fish-shaped microbots - that they call microfish - which can swim around efficiently through liquids, powered by hydrogen peroxide and are magnetically controlled.
We're all guilty of bringing home useless items like flyers or old computer electronics from time to time, hoping that one day we'll use them. Don't kid yourself. It rarely happens. For some people though, hoarding seems to be a way of life, bordering obsessive compulsive disorder. In fact, psychologists class hoarding behavior as a distinct disorder which affects 2 to 5 percent of Americans.
Scientists from the Scripps Research Institute (TSRI) and Janssen Pharmaceutical Companies of Johnson & Johnson (Janssen) have discovered a way to give antibodies the ability to fight a wide range of influenza subtypes. Their work has great potential to one day eliminate the need for repeated seasonal flu shots.
Though initially made for narcoleptics (people having trouble sleeping), many soon caught on that modafinil can enhance cognitive abilities. Right now, it's a favorite among students who use it when preparing for exams with visible results, they claim. But modafinil isn't the first such "smart drug" we've come across. It's likely that you've seen some TV or internet ads marketing 'smart pills' that supposedly enhance cognitive abilities, but with mere anecdotal evidence backing it up. In contrast, modafinil really seems to be a legit smart drug, according to a systematic review of reports documenting the effects of the drug. The meta-analysis was made by a team at University of Oxford and Harvard Medical School.
Several cultural beliefs and modern social practices may hinder children's mental, moral and emotional development, finds a study by an interdisciplinary body of research presented recently at a symposium at the University of Notre Dame.
When someone yawns near us, we naturally feel an irresistible urge to yawn in response. Even dogs seem to yawn when humans do it. This contagious behavior has fascinated psychologists and behaviorists for many years, and while there are many reasons scientists have proposed for why people yawn (it's a bit complicated, what we know for sure is that's important and actually has a purpose), social cohesion might play an important role. The more emphatic you are, the likelier it is you'll yawn in response. On the contrary, psychopaths barely register yawns and seem impenetrable.
Inventions are at the very core of human development, and quite often, the scope of the invention is not easy to grasp. Such is the case with a new "vomiting machine" which will be used to study noroviruses - fast spreading viruses that cause acute gastroenteritis.
Just in time for back-to-school season, a group of researchers report that lice in more than 25 states have become resistant to the common over-the-counter treatments. Every year, up to 12 million kids aged 3 to 11 get infested with head lice, which apart from being extremely unpleasant and annoying can create complications when a child overly scratches its scalp, forming wounds that can get infected. Now that lice populations have grown resistance to insecticides, it will be increasingly difficult to get rid of them.
Staring straight into someone's eyes can be pretty intense, and is usually avoided by most people. But a team of researchers has shown that it's even weirder than you'd think: it actually alters your consciousness, and often causes hallucinations.
Researchers at University of Southampton, England report finding an alternative pathway to activate a key enzyme involved in cellular glucose uptake, mimicking the effects of exercise (some of it). In type two diabetes the enzyme in question is "lazy" and drugs are usually used to activate it, allowing glucose to enter the cell and produce energy (adenosine triphosphate or ATP for short). It's not clear yet whether the new molecular compound, for now simply called 'compound 14', is better than current treatments.
Television has perpetuated the already classic image of a violent, psychotic criminal, up to the point where we basically associate the two. We often tend to think of violent people as psychotic, and psychotic people as violent. But as a new study has found, that's not really the case: there's no strong correlation between violence and psychosis.
Using and understanding the intricacies of sarcasm is a fine art; one does not simply “become” sarcastic – you must dive into it, let it embrace you. You must become sarcasm. But jokes aside, sarcasm is a strange thing – we don’t know exactly how it appeared and why. The best theory seems to be […]
A research group has come up with an innovative way of dealing with blood clots through nanotechnology. This technology has the potential to save many lives every year, as blood clots are often associated with life-threatening events.
One of the most peculiar languages in the world, whistled Turkish, is challenging the long-standing idea that the left brain hemisphere is solely responsible for processing language and extracting meaning. Any language, be it spoken, written or signed is processed in the left hemisphere, but whistled languages are processed equally by both sides of the brain. It's a striking discovery that suggests people devoid of left hemisphere processing abilities, following a stroke for instance, can still communicate using their right hemisphere. Just whistle.
A drug called Flibanserin, also known under the name of Addyi, is marketed as the first designed to boost a woman's sexual desire. This week the FDA will decide whether to approve the drug or not, however looming safety concerns could count against Sprout Pharmaceuticals, the parent company marketing the Flibanserin.
Taking a page from the oil industry “sponsorship” philosophy, Coca Cola spent millions funding scientists to say that soft drinks don’t make people fat. While there’s nothing inherently wrong with a company funding scientists to study its products, when the result is already known before the study actually starts, that’s not exactly science – that’s […]
