Culturing mammalian cells is currently the only way to make some complex proteins used in certain drugs; but growing such cultures is an extremely difficult and delicate job, because they can harbor human pathogens and must therefore be kept under strict temperature conditions. It’s a difficult job, but it’s definitely worth it; take a look […]
No person is the same, thanks to genetic variation. While skin color, hair, or body proportions are elements that might be exactly the same for two persons, you can be sure that one’s face is unique – even in identical twins, if you look extremely closely. While life style, body weight, diet, accidents and so […]
Dr. Jay Bradner, a physician and chemical biologist at the Dana-Farber Cancer Institute in Boston, makes beating cancer sound easy – darn easy! Through the wonderful information that epigenetics science has delivered in the past decade, he believes cancer can be defeated simply by re-writing its genetic information such that it forgets that it’s a cancer, and […]
Two recently released studies by teams of international researchers sequenced the genomes of two major strains of the parasitic disease known as malaria. Their findings show that malaria is a lot more resistant than previously thought, but at the same time helps paint a broader picture which will certain aid in developing more effective treatment, […]
In what can only be described as a milestone in biological and genetic engineering, scientists at Stanford University have, for the first time ever, simulated a complete bacterium. With the organism completely in virtual form, the scientists can perform any kind of modification on its genome and observe extremely quickly what kind of changes would […]
Researchers have analyzed the DNA from 7,000-year-old bones of two cavemen unearthed in Spain, and have managed to sequence fragments of their genomes, making them the oldest modern human specimens ever found thus far. Ironically, the researchers found that the cavemen bear little genetic resemblance to people living in the region today, instead sharing ancestry with current populations […]
A newly published researchers by scientists at University of California Davis and Cornell University explains why beautiful, perfectly ripped tomatoes, that one can typically pick up from a local supermarket, are ironically less tastier than homegrown tomatoes, which look less appetizing. I had the good fortune of spending most of my early childhood in the […]
Genetic diversity is what keeps species evolving, helps them tackle diseases and is a prime pre-requisite for natural selection. Understanding genetic diversity is imperitive for scientists in the field, whether it’s about identifying associations between genetic variants and diseases or highlighting interesting aspects of human population history. One of these aspects is geographical location. Remarkably, an international […]
You too can get a genetic test kit for your samples! A new university-based project seeks to investigate cryptic species, such as yeti for example, in an attempt to show if these species can actually exist or not; and they want to do this through DNA research. Researchers from Oxford University and the Lausanne Museum […]
Another breakthrough in biology and medicine was reported, as scientists were able, for the first time, to take skin cells from patients who had suffered heart failure and make them repair the cardiac muscle. The technique had been tested only on rats and it seemed decades could pass until it would become suitable for humans, […]
Horses are arguably one of the most helpful animals man has ever managed to domesticate. At first they were used as source of meat and milk, but it was soon evident that horses were a lot more suited as labor animals than as a direct food medium. Important agricultural advancements were made possible thanks to horses, and […]
Skin and hair color are most inherited from parents, and usually hint pretty accurately to a person’s ethnicity. Dark skin and hair are most common in the regions around the Equator, however natives of the Solomon Islands, an archipelago east of Papua New Guinea, seem to defy common expectations, as around 10% of the population […]
Scientists at UK Medical Research Council’s Laboratory of Molecular Biology have successfully managed to create an artificial version of both DNA and RNA, fundamental biomolecules crucial to life. The synthetic nucleic acids are capable of encoding information and passing it on to the next generation, even with changes in the code with the help of an […]
A study performed last year observed that identical twins, who share 100% of the same genetic material and had the same upbringing, expressed a very similar attitude towards civic behavior and care-giving, whilst fraternal twins, who share 50% of their genes and, again, had the same upbringing, did not necessarily share the same pro-social attitude […]
When the brain deems an experience meaningful enough, it will transfer that information from short-term storage, where typically information like where you put your car keys or the phone number of a person you just met gets stored temporarily, to your long-term memory, offering the possibility to be accessed at a later time. Neurologists claim […]
There are a number of factors that lead to obesity, the most obvious of which is of course eating too much, without burning the excess fat by exercising. Fact is, there are some people in the world who no matter how much they’d eat, they never seem to be satisfied, constantly consumed by a sense […]
A remarkable research whose findings recently published in the journal Cell, concludes that intense physical exercise leads to chemical alteration of the DNA, turning certain genes on and off. In fact, individuals which lead a relatively sedentary lifestyle changed the DNA in their muscle fibers almost immediately, after a strenuous 35 minute work-out. It’s important […]
Researchers have completed the great apes family’s genetic library after they sequenced the genes of a western lowland gorilla, joining the already-sequenced genomes of humans, chimpanzees and orangutans. Scientists found that gorillas, which share 98% of their genes with humans, are a lot more related to humans than previously thought, as well as surprising genetic differences which […]
For a number of years now researchers have been studying the sirtuin gene and the proteins encoded in it as it is believed to be directly linked to prolonged lifespan. A myriad of individual studies were performed with mixed results, and so far hundreds of millions have been allocated for research in this direction. A […]
Good news for men, and especially women: the Y chromosome, which holds the male sex determining genes in most mammals, including humans, is not going extinct, as some claim, as a new research found that the diminishing gene numbers have come to a halt and will remain this way. Sex chromosomes come in pairs, such […]
Since the advent of modern DNA sequencing technology, biological research and discoveries has been dramatically accelerated. It’s absolutely instrumental to genetic research nowadays, which among other great achievements, has lead to the sequencing of the human genome. The methods and technologies involved in DNA sequencing are terribly complex, however, and usually require sophisticated research laboratories. […]
Last year, researchers at the Max Planck Institute for Evolutionary Anthropology, produced a draft of the Denisova genome, in order study in what proportion they relate to homo sapiens sapiens. The Denisovans, are a new group of hominids, discovered just two years ago, which is believed to have lived around 30,000 years ago, alongside Neanderthals and […]
Darwin’s theory of natural selection illustrates perfectly what evolution is all about, the survival of the fittest if you will. It’s because of natural selection that a crocodile has an armor-like skin to protect it against enemies, a chameleon can change its color and camouflage itself for protection and hunting or humans evolved a more […]
In Greek mythology, the chimera is a fire breathing beast composed of several animal parts (lion body, snake-head tail, a goat head hanging from its back and so on), which has spurred the imagination of man for thousands of years. Though it is fairly clear that such an abomination never existed, apart from the infinite recesses of […]
In a recent post I was telling you about Russian and Japanese researchers working together with the purpose of cloning a mammoth from bone marrow DNA recently found in Siberia. However, many researchers are extremely skeptical about this, including some of the world’s leading experts. “C’mon, it’ll never happen. Not in my lifetime,” said Webb […]
Scientists from Russia and Japan searching in the permafrost soil in Siberia have found mammoth remains so well-preserved that they believe they will actually be able to clone it, using its bone marrow. Teams from Sakha Republic’s mammoth museum and Japan’s Kinki University have embarked on this quest, vowing to find how this can be […]
A stroke of pioneering science, researchers have managed to restore hearing to a significant level in guinea pigs by using gene therapy, bolstering hope for a similar procedure to cure human deafness in the future. The therapy works by promoting the regeneration of hair cells in the cochlea, the part of the inner ear which […]
Amidst of all the talks and protest against stem cell treatment and companies shutting down, nature has found its own way of treating diseases with stem cells. When a pregnant mouse mother, for example, has a heart attack, her fetus donates some of its own stem cells to help and cure. Researchers started working on […]
Scientists from the École Polytenchnique Fédérale de Lausanne (EPFL), with the aid of colleagues from the Salk Institute for Biological Studies and the University of Lausanne, managed to improve the muscle constitution of mice by knocking out genetically a “co-repressor” of the DNA transcription process. The end product are mice that are faster, stronger and healthier […]
Scientists have genetically engineered mice able to express a certain enzyme, which allows for an increased metabolic rate. The lab mice infussed with this enzyme in their fat tissue were able to eat more, but gain far less weight than their naturally bred brethren. It’s generally acknowledged that obesity and inflammation cause insulin resistance, however […]
The sonic hedgehog gene got its name after researchers did some testing on fruit flies embryos, and found that the specimens which were modified to lack the gene developed spine-like projections. The gene itself is crucial to body development; to put it in layman terms, the sonic hedgehog gene makes sure that all your limbs […]
Researchers at Linköping University have taken up themselves to study the intricate personality of the sperm donor. What they found was that men who cared enough to preserve their heritage were more stable and mature than non-donors. Rather extensive, as part of the study the researchers asked donors from all of Sweden’s seven sperm banks to […]
The black plague, or black death as it’s also referenced, is a deadly infectious disease which killed off more than a third of Europe’s population during the middle ages. The bacteria responsible for the disease has been confirmed by genetic scientists as Yersinia pestis, and recently, building off the research which found this particular strain, […]
Scientists from the UK and Hungary have run various experiments to verify the claim of US researchers that a certain gene is responsible for the increase of lifespan, as shown in some test organisms. Their results show, in fact, that the so called “longevity gene” allegedly responsible for the generation of an anti-aging protein doesn’t […]
In 2008 a deadly earthquake hit the Sichuan province of China killing tens of thousands and living millions homeless – it was the most devastating natural disaster in China’s recent history. From the among the rubles of the quake, however, emerged a survivor-pig which made him an instant national hero at the time. Now, Chinese […]
Common sense might tell you that only mammals are capable of lactating, it’s a little know fact, however, that some species of birds are also capable of making milk for their young. The common pigeon produces milk in its crop, located near the esophagus, to feed its young. Scientists have long been wondering how the […]
The mating between Neanderthals and modern homo sapiens has been a highly controversial matter between scientists in the anthropology scene for decades now. That was until last year, however, when anthropologists convened that the two related species did indeed mate, but the genes passed down from Neanderthals were inactive. Recently, there’s been another reason for […]
In a recent groundbreaking research study, scientists from Seoul National University in South Korea have successfully created a dog that can glow in the dark, using genetic engineering techniques. This achievement holds the potential for finding cures for human diseases such as Alzheimer’s and Parkinson’s. The dog in question, a genetically modified female beagle named […]
News of a low-cost semiconductor-based gene sequencing machine has been reported this Wednesday in the journal Nature, by a team led by Jonathan Rothberg. The astonishing advancement might lead to a age of personal human genome sequence, where people will be able to decipher their own DNA for as low as $1000. The human genome was […]
There has been a long standing debate regarding the Neanderthal people, and what kind of legacy we carry from them. Recently, a study conducted by an international team of researchers led by Damian Labuda of the Department of Pediatrics at the University of Montreal and the CHU Sainte-Justine Research Center showed that a part of […]
First of all, I hope you’re having a great Summer so far, and I apologize for my leap of absence – I’ve been missing you guys. If you want to know the history of your ancestors, you don’t have to look any further than your own body. As it turns out, your own genome carries […]
If we’re to guide ourselves after Aubrey de Grey‘s telling, according to his predictions the first person who will live to see their 150th birthday has already been born, and as science advances along the decades at the current pace it does, he claims people born soon after the latter mentioned birthday will live to […]
In a recently patented research, UCLA geneticists have shown and demonstrated how they’ve accurately been able to predict a person’s age just by analyzing a saliva sample. The research could possibly find highly welcomed applications in crime scene investigation, as a forensics tool for pinpointing a suspect’s age. “Our approach supplies one answer to the […]
Pictured above is a cardinal, and if you don’t see anything special about it yet, you should check out its plumage. Alright, maybe not all of us are ornithologists, so I’ll just set the facts straight. If you look closely, you’ll see that the bird has bright red plumage of a male on its left […]
Researchers have managed to restore light perception to mice through gene therapy, by inserting algae genes into the retina. The treatment has succeeded in restoring the ability to sense light and dark to blind mice, and clinical trials in humans could begin in as little as two years. “The idea is to develop a treatment […]
While gene-therapy is still regarded as a very innovative practice, it seems like the procedure might take traction as of today when remarkable results were concluded after the first successful double-blind gene therapy for Parkinson disease. In the case of this dreadful disease, medical researchers injected patients with a a gene that codes for glutamic […]
I recently finished reading The Generous Man by Tor Nørretranders in which the author tries to explain the awkward act of giving away, charity, by invoking social mechanics – sex to be more accurate. People are generous, and by giving they prove they posses enough resources and skill to make it in the world with […]
The lead singer, rock legend bat beheader has done pretty much anything you can do in this life. He played in front of thousands, ate/drank/smoked/injected pretty much everything that can be, had motorcycle accidents, never ate right, and yet, at the proud age of 61 he’s alive and kicking just as he ever was. Researchers […]
In was is a historic day, US doctors have officially begun the first trial of using human embryonic stem cells, as a result of the green light they got from regulators. The controversial method has been on the table for quite a while, and now The Food and Drug Administration has given a license to […]
Mice have been used for research in nearly every field, be it medicine, psychology or genetics. In one recent finding regarding genetics study on mice published in the BMC Genetics journal, scientists have managed to turn mice gay by simply altering their genome structure. How so? Well, it seems a group of scientists from Korea’s […]
