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 […]
People from the Americas may have been making their way to the Easter Island way before Dutch commander Jakob Roggeveen arrived in 1722, according to new genomic evidence; this new evidence showed that the isolated Rapanui people shared a strong connection with Native American populations hundreds of years earlier. This evidence shows that early Americans undertook the […]
A new milestone study found that mitochondria – the energy factories in animal and plant cells – were initially very similar to parasitic bacteria some two billion years ago, and only later did they become energy sources. Very little is known about the origins of mitochondria, but by probing the genomes of bacteria closely related to […]
It’s common knowledge that babies born out of tall parents will most likely grow to be just as tall, but it’s only recently that scientists report finding most of the genes responsible for height. Information like this could prove to be useful in diagnosing genetic growth deficiencies or, in the not so distant future, genetic manipulation to […]
Most organisms, including humans, have parasitic DNA fragments called ‘jumping genes’ that insert themselves into DNA molecules, disrupting genetic instructions in the process. This phenomenon can interfere with the good health of the individual, causing numerous conditions, including cancer. Now, a new study has documented how a protein called Sirt6 keeps these fragments (technically called retrotransposons) at […]
It wouldn’t be an understatement to say we owe all the wonders of life to photosynthesis – the ability of plants and certain bacteria to convert CO2 into energy (sugars) and food. Scientists have for some time attempted to enhance photosynthesis through genetic manipulation, but it’s only recently that we’re beginning to see these efforts […]
While you might find people sometimes resemble each other, if you look close enough you’ll soon find unique features and facial characteristics that sets them apart. It’s remarkable how diverse human faces are across the billions alive today and the countless billions that used to live in this world. Scientists at University of Berkeley now […]
A new study concluded that schizophrenia isn’t a single disease, but rather a group of eight genetically distinct disorders, each with its own set of symptoms, and likely, its own treatment. The study could be the first step in finally understanding the condition and how it can be dealt with. Currently, schizophrenia is thought of as a […]
A Japanese woman in her 70s is the world’s first recipient of cells derived from induced pluripotent stem cells, a technology that promises to work wonders and has the scientific community excited about the perspectives. Surgeons working on the case created the retinal tissue after reverting the patient’s own cells to ‘pluripotent’ state. If you’d like to […]
A whole functional organ has been successfully grown in animals for the first time; a group of Scottish researchers created a group of cells which, when transplanted into a mouse, developed into a fully functional thymus – a critical part of the immune system. The findings could lead to a revolution in organ transplant. The […]
It’s one of the most remarkable adaptations in the animal world – growing a tail or a limb. Some lizards do it, salamanders do it, and by learning how they do it, we may soon be able to do it as well; with technology, that is. A team of researchers have discovered the genetic “recipe” for […]
Researchers at the Max Planck Institute of Immunobiology and Epigenetics (MPI-IE) re-activated the expression of an ancient gene in mice. To their surprise, the gene in question which is dormant in all mammalian species caused the mice to develop fish-like thymus. The thymus is an organ of paramount importance to the adaptive immune system, but in […]
A brave Australian professor of molecular biology thinks he may have found out why women get premenstrual syndrome (PMS). According to his findings, following genetic screenings, PMS has evolved as a mechanism for breaking up infertile relationships and thus increase the chance of fostering a fertile relationship in the future. Effectively, nature designed PMS to […]
When you think about fish oil, you probably wouldn’t think of the English countryside – but that’s exactly where scientists are trying to grow it; yep, grow it! They’re using Camelina sativa plants genetically modified to produce long chain omega-3 fatty acids—the primary component of “fish oil.” Things you didn’t know about fish oil Most of the fish […]
In 1944, the Nazis caused widespread famine in Western Netherlands after they blocked food supplies. A group of pregnant women living in the Netherlands, labouring under starvation conditions imposed by a harsh winter and food embargo, gave birth to relatively small babies. When their children grew up, in relative prosperity, to have children of their own their babies were unexpectedly small.
Computer games could be the key to treating elderly people who have been diagnosed with depression, but who aren’t responding to conventional treatment. A new study has shown that playing a certain type of computer games was more effective at reducing symptoms of depression than the “gold standard” – the antidepressant drug escitalopram. Recently, we’ve been bombarded about […]
HIV is maybe one of the most resilient and tenacious viral infections known to medical science. Unlike other infections, even if all traces of HIV are gone from the body – the virus itself – it can still resurface and infect the patient later on. That’s because HIV inserts itself permanently into the patient’s genome, […]
Right now, I’m the happy caregiver of seven cats (five kittens. Yey!) which in most people’s books makes me socially challenged and insane. I do take special notice of my pets, and this means looking after them so they don’t get infected by parasites. Cats are typically clean animals, but when infested can spell trouble […]
An unlikely worm might help millions of people fighting alcohol addiction. No, you won’t find it in tequila, but in the labs of neuroscientists at University of Texas at Austin who have engineered Caenorhabditis elegans – one of the most popular animal models in science – to become insensitive to alcohol intoxication. The findings, if replicated on […]
We often cherish our closest friends as if they were family. Well, this isn’t actually too far from the truth, considering a new study from the University of California, San Diego, and Yale University found friends who aren’t biologically related resemble each other genetically. In fact, on average friends are as “related” as fourth cousins […]
Researchers at the Sanford-Burnham Medical Research Institute (Sanford-Burnham) have found a chemical switch that both regulates the generation of new neurons from neural stem cells and the survival of existing nerve cells in the brain. Postmortem examination of the brains of Alzheimer’s patients and stroke victims found the switch that shuts off the signals was […]
Advancements in genetic sequencing has allowed genomic research to flourish. DNA sequencing is now much faster, cheaper and accurate than ever before, and we’re only now beginning to reap the rewards. It’s the first step to a complete understanding of our bodies. The Human Genome Project, once finally completed, mapped and identified all the genes of […]
According to latest estimates by the World Health Organisation, over 3.4 billion people are at risk from contracting malaria and an estimated 627,000 people die each year from the disease. Thanks to the painstaking efforts of leading researchers in the field, however, much progress has been made in curbing down on malaria. Since 2000, increased […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
Scientists have shown that trauma can leave epigenetic marks – chemical changes that affect how DNA is expressed without altering its sequence. Basically, your traumatic experiences genetically affect your offspring. Scientists have recently focused on the long term after effects of trauma, finding them to be numerous and diverse. The offspring of traumatized people are at […]
It’s a truly terrifying story, and a truly terrifying disease. The flesh-eating culprit in question is called GAS, or Group A β-hemolytic streptococcus, a highly infective bacteria. Apart from causing the flesh-eating disease necrotizing fasciitis, GAS is also responsible for a range of less harmful infections. But like most bacteria, it was harmless at one point in its […]
The origin and evolutionary history of modern lions has been revealed through genetic analysis. This recent study suggests that the lions’ most recent common ancestor lived around 124,000 years ago. A fallen king Modern lions evolved in two different groups – one of them currently lives in Eastern and Southern Africa, the other includes lions […]
As incredible as it may sound, scientists have successfully reversed the aging process in mice, according to a new study published in Cell. Reversing aging, a real possibility? Many of the chronic diseases that exist in older adults constitute a highly significant social and economic burden to the community; if you think about it, eliminating […]
In a huge breakthrough in synthetic biology, scientists at Johns Hopkins University have engineered from scratch a yeast chromosome. This is the first time scientists have been able to assemble a chromosome from a creature as complicated as a yeast, namely a prokaryrite. The implications of this research are far and wide. For one, the […]
Sea anemones are remarkable creatures. They are a group of water-dwelling, predatory animals, but if you look at them, they look like plants more than animals. Now, a team of evolutionary biologists from the University of Vienna has discovered that sea anemones display a remarkable genome, featuring a complexity of regulatory elements similar to that of fruit […]
The largest clinical study ever conducted to date of patients with advanced leukemia found that an incredible 88% of patients entered remission after being treated with genetically modified versions of their own immune cells. It’s like the medicine of tomorrow – today; and it’s super effective. “These extraordinary results demonstrate that cell therapy is a […]
Human embryonic stem cells can be induced into forming a developing brain tissue. The brain development process represents one of the most specific processes; during it, neuroepithelium, formed as a flat sheet by the nervous system, grows on the exterior layer of the embryo, after which it folds in to create a neural tube giving […]
Sure to raise a slew of controversy and debate, researchers in Japan are currently investigating the possibility of growing human organs, like kidneys, livers or even hearts, inside pigs. A real life chimeric tale, as if spawned from the Island of Dr. Moreau. The challenges are numerous though, both technical (we’re talking about growing human […]
Some people just have the knack of remembering the face of everyone they’ve met in their lives, while others, on the opposite end of the spectrum, have a difficult time recognizing who they met yesterday. Now, researchers at Emory have identified the oxytocin receptor, a gene known to influence mother-infant bonding and pair bonding in monogamous […]
Just like taste, it’s really common for people not to agree on how pleasant or fowl a scent may be. You might find the meal you just cooked to have a pleasant odor or you might have bought a perfume you thought smelled divine, only for some other person to disagree and express a distaste. […]
From the common cold to pneumonia and potentially life threatening lung diseases: a single protein was found to play a key role. Now, an international team of researchers has finally zeroed in it. The key protein is called MUC5B – it is one of the two proteins found in the mucus that normally and helpfully […]
Mice in the control group refused to drink alcohol When a certain gene was deactivated, they started preferring alcohol over water Researchers stress that human alcoholism depends much more on environmental and personal factors Researchers have discovered a gene that regulates alcohol consumption; when this genes becomes faulty, it makes humans more prone to […]
University of Utah researchers found that female mice that live in a competitive social environment and choose to mate casually with multiple partners give birth to males who are much more attractive to female mice, at the cost of a dramatic cut in life expectancy however. You only have one life, says the sexy male […]
It’s not the cancer tumor itself that kills people, but rather the spread of cancer cells is what ultimately may bring the killing blow to patients. This is called metastasis, and oddly enough not nearly enough is known about how it works. University of Minnesota researchers have devised a pathological method for doctors to assess whether […]
You’ll be pretty impressed by this novel research. Scientists at University of Iowa have developed an ingenious biopatch which expels nanoparticles containing DNA that instructs cells to turn into bone. Practically, you just apply this patch over a damaged area that needs reconstruction, dental surgery site or congenital bone defect and the genes do the rest of […]
Researchers from North Carolina State University, the University of North Carolina at Chapel Hill and Laser Zentrum Hannover have worked together to discover a natural compound which can be used in the 3D printing process of creating medical implants out of non-toxic polymers. The compound goes by the name riboflavin, but is better known as […]
One of the greatest mysteries scientists have been trying to reveal is how inanimate chemicals joined to produce life. It’s definitely one of the biggest questions scientists are trying to answer, and the challenges are numerous since it’s very difficult to appreciate what the exact conditions necessary for this to happen were billions of years […]
Anti-baldness treatments available today work by stimulating hair follicle health or slow down hair loss. There is no available method that promotes the growth of new hair, however. You might have heard of hair transplants, but this typically involves transplanting hair from another area of the hair, like the back of the head, to the […]
Faeces based treatment halts the advance of Clostridium difficile bacteria, but a commercial treatment is still far away. Using a faeces in the treatment of the gut infections and diarrhea is not a new idea, though it’s still in its initial stages. In 2010, we told you about a woman who had a life threatening […]
