Unexplained excess mass in human chromosomes puzzles scientists
Humans have 23 pairs of chromosomes, only one of which determines a person’s sex-linked characteristics. The remaining 22 pairs contain bundles of genetic instructions that help determine the other, non-sex-related traits. Since the discovery of DNA, researchers have endeavored to learn all there is to know about these coded sequences, including how much they weigh. The […]

Do you have a median artery? Researchers say it’s proof humans are still evolving
Researchers say humans are still evolving, and they’re evolving at a faster rate than at any point within the past three centuries. The increased prevalence of a structure known as the median artery — which typically regresses in the second month of gestation — in people born by the end of the 20th century is proof of […]

Researchers explain how serotonin is linked to somatic awareness, a condition with unexplained symptoms
People who suffer from chronic pain often report somatic awareness, a condition marked by heightened sensitivity to a variety of sensations and symptoms. These non-specific symptoms, which often include headaches, sore joints, itchy skin, constipation or shortness of breath, have no physiological explanation; nevertheless, they are enough to cause emotional distress to those who experience them. Despite […]

Medical doctors STUNNED as bone marrow transplant for leukemia treatment changes man’s DNA, proving medical interventions can OVERWRITE your genetic code
A Nevada man was shocked to learn that a bone marrow transplant he received actually changed his DNA and replaced it with that of his German donor. Chris Long of Reno is currently in remission from acute myeloid leukemia. Three months after his bone marrow transplant operation, he discovered that the DNA in his blood […]

Next-gen spider silk will come from bacteria and will be used on space missions
Scientists have come closer to revealing the secret to Spider-Man’s webs. In a study presented at the American Chemical Society’s National Meeting and Exposition, researchers from Washington University in St. Louis, led by Fuzhong Zhang, demonstrated that engineered bacteria can mass-produce spider silk and other useful proteins for space missions. The challenge of large-scale silk production Silk […]

Promising new research suggests targeting the endocannabinoid system to treat cognitive disorders
Spanish researchers found new hope for patients with cognitive disorders like Down syndrome. Their experiment on cognitively-impaired mice revealed a link between Down syndrome and the endocannabinoid system. Furthermore, they identified cannabinoid receptor type-1 (CB1R) as a possible target for the treatment of Down syndrome. Mental disability stems from many causes, including genetic problems. The most widespread of […]

Having constantly stressed ancestors may improve your own immune response to stressors, suggest research
A new study showed that the descendants of lizards who lived in high-stress environments developed stronger immune systems than those descended from lizards who lived in low-stress environments. Based on this discovery, researchers should consider looking at family history in future studies investigating stress and its effects on health. Long periods of stress can compromise the immune system of an organism, rendering it more vulnerable to […]

Understanding innate fears: Scientists study why snakes and spiders evoke a stress response, even in babies
Why are human babies afraid of creepy-crawlies such as spiders or snakes? Is it something that they learn as they grow older? What about extremely young infants who have never been exposed to these creatures beforehand? According to new research from the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS), the answers to […]
