The discovery highlights how trait functions can change with evolution.
Dandruff is the most common scalp condition, yet we know surprisingly little about it.
Goosebumps are strange. We get goosebumps when we’re cold, when we’re afraid, and sometimes when we’re really excited – three very differen
Creating artificial skin may sound weird, but it can be extremely useful (or even life saving) for people who suffered from burns or any type of similar accident; it is also useful for testing drugs or cosmetic products. Skin transplants are a growing need, and many teams from across the world hope to one day be able to create artificial
A new study has mapped the genetic variations responsible for differences in the distribution, shape and colour of facial and scalp hair.
I like my ears. I’ve been told they go well with my face and they’re really efficient at holding my hair out of my eyes, like ad hoc hair band. And I get two of them! Yay for ears!
But (spoiler alert) these are not our ears’ primary functions. The workings of our ears’ internal mechanisms underpin two of our senses — hearing and balance (called equilibrioception).
How eyesight works and other functions.
Researchers at the Washington University School of Medicine in St. Louis, looking into the effects depression has on the brain have found proof linking the disorder with abnormal brain development in preschoolers. Their study, published in the journal JAMA Psychiatry, shows how gray matter is thinner and lower in volume in the cortex, an area of the brain that plays a key role in processing emotions.
Scientists from the University of Ferrara, Italy collaborating with the Beijing Genomics Institute have isolated a gene that, when mutated, causes muscle tissue to become significantly weakened and damaged. Their findings, published in The Journal of Clinical Investigation, show how the gene, dubbed Popeye domain containing-1, has a role in ‘gluing’ muscles cells together.
In a new study published in Nature, researchers have demonstrated a technique that allows the mapping of organs at microscopic scales.
The blood-brain barrier has been broken for the first time in history, and this can revolutionize some areas of cancer treatment.
Scientists have gathered a completely new understanding of how blood is formed in the body, potentially revolutionizing the dogma standing since the 60s.
Scientists have in the past toyed with the idea of using a disease to fight cancer. Now, after identifying a malaria protein that binds to cancer cells and kills 95% of tumor types, human trials are expected to start within four years. I doesn’t seem like it’s happening fast, but it is, in medical terms. Clinical trials take a lot of
A few days ago, we were telling you about a potentially groundbreaking study which found a rather surprising correlation between height and cancer incidence. The study made quite a wave within the scientific community and was met with quite mixed opinions. Here are some of those impressions, from leading experts in the field. Prof Mel Greaves, Director of the Centre
For the first time, Japanese researchers have successfully grown a pair of kidneys in a lab and then transplanted them into animals. The organs functioned just fine, and this gives big hopes for the transplants ultimately moving to humans.
In our day to day lives, we don’t give much thought to tears – we usually focus more on the emotions that cause them than the salty droplets themselves. Well, tears are much more complex than we give them credit for, as Dutch artist Maurice Mikkers showed. Tears Caused By Emotional Response: There are actually three main type of tears: basal
Though it enjoys to sit or lie down from time to time, the human body is made for moving not sitting. It’s all hardwired in our biology. Inside, there are about 360 joints and about 700 skeletal muscles that enable easy, fluid motion. Our skin is stretchy. The blood circulates best when the body is upright. Basically, every cell in our body itches for a walk. But when you sit down for too long, all sorts of health problems can arise from back and muscle pain, to more threatening long-term problems like hearth disease or cancer. I’ll leave you to Murat Dalkilinç in this extremely enlightening, but also practical TED animated video.
A pair of anthropologists compared the anatomical features o bonobos to those of homo sapiens and other apes to infer any clues that might help us understand how we evolved to look the way we do.
Researchers at MIT have now identified a neural circuit that they believe underpins decision-making in situations such as this, and have started looking into mice’s brains to better understand the biological processes that make us tick and help us pick.
Ever wondered what chins are good for? Upon a quick reflection, you might think it actually has some practical value, supporting your jaw against the massive chewing forces. But that’s nonsense. It doesn’t do any of that, as a recent research concludes. In fact, the chin – the last facial feature to stop growing – actually makes the jaw less resistant to the bending stress of chewing as we age. Though still a mystery, scientists believe the chin is actually a side effect of the rest of the face having become smaller. Much smaller than that of early ancestors or cousin Neanderthals, at least.
