The young blood won't make you younger, the old one can be toxic

Despite the success he is having lately (Silicon Valley billionaire Peter Thiel, for example, has expressed interest in it), receiving blood transfusions from young people will not rejuvenate your body, which Dracula. A study published in the journal Nature Communications denies it, although it warns of something else: the blood of elderly people could be toxic.

A new sensory organ is identified in our skin that informs us of puncture pain
Researchers at the Karolinska Institute in Sweden have discovered a new sensory organ that can detect painful mechanical damage, such as punctures and impacts. The discovery is published in the journal Science. The study describes how the new pain-sensitive organ is, how it is organized along with the nerves sensitive to pain in the skin and how the activation of the organ produces electrical impulses in the nervous system that produce reflex reactions and an experience of pain.

A team of scientists in Korea and the United States have published in Nature Biomedical Engineering the details of a device that can control neuronal circuits using a small brain implant controlled by a smartphone. The researchers argue that the device could facilitate diagnoses of diseases such as Parkinson's, Alzheimer's, addiction, depression and pain.
The vibration of the body to produce a higher percentage of macrophages and prevent diabetes
The vibration of the body to produce a higher percentage of macrophages and prevent diabetes
Obesity has been identified as one of the main risk factors in the development of type 2 diabetes. On the other hand, it has also been observed that alterations in the intestinal microbiota played a role in the appearance of both obesity and Type 2 diabetes. Does this mean that a modification of the gut microbiota could contribute to cause, prevent or manage type 2 diabetes?
This blood test has 94% accuracy to identify early Alzheimer's disease
This blood test has 94% accuracy to identify early Alzheimer's disease
Researchers at the University of Washington School of Medicine in St. Louis suggest that they can measure levels of Alzheimer's beta amyloid protein in the blood and use those levels to predict whether the protein has accumulated in the brain. This protein is important, because it begins to accumulate up to twenty years before people develop Alzheimer's.

Activated carbon to lose weight and detoxify the body: this is what science says about it
A few years ago the "black food" fashion began. To these striking foods, activated charcoal is added to give it that color and attribute a thousand wonders to our health. Who would want to coal their food? Activated carbon is of a "special" type, capable of trapping many types of particles.
You are more likely to get sick and die of the flu from a key factor: low humidity
You are more likely to get sick and die of the flu from a key factor: low humidity
A group of Yale researchers have pointed out a key reason why people are more likely to get sick and even die of the flu during the winter months: low humidity. We already knew that low temperatures and low humidity promote the transmission of the influenza virus, but it is less understood about the effect of the decrease in moisture in the immune system's defenses against influenza infection.
This is the first time a drone is used to deliver an organ for a transplant.
This is the first time a drone is used to deliver an organ for a transplant.
Drones could take donor organs to recipient organs faster than traditional transport methods, which increases the likelihood that organs will remain "viable" when they reach their destination. In the first test in this regard, conducted last month, a drone delivered a kidney for a 44-year-old woman in Baltimore with kidney failure and had spent eight years on dialysis.

When it comes to losing weight, is it better to lower carbohydrates or fats? Science has the answer
"Are you more fat or carbohydrate?" You may have heard this phrase on occasion. The issue seems to simplify too much a problem that affects everyone. Obesity is the most widespread epidemic, and on the planet who doesn't want more quality of life? The answer is complicated.
Artificial Intelligence can now detect breast cancer up to five years in advance
Artificial Intelligence can now detect breast cancer up to five years in advance
A new way of analyzing mammograms, using artificial intelligence algorithms, which has been developed by MIT researchers allows to help detect breast cancer up to five years in advance. Specifically, a deep learning model created by researchers from the Laboratory of Computer Science and Artificial Intelligence (CSAIL) and the Massachusetts General Hospital is used, which not only allows predicting future breast cancer, but, unlike previous methods , works equally well in both black and white patients.
This injectable gel could one day rebuild muscles, skin and fat
This injectable gel could one day rebuild muscles, skin and fat
A group of researchers has developed an injectable gel reinforced with nanofibers that can rebuild muscle and connective tissues by serving as a scaffold and recruiting wound healing cells from the body. Until now, the team has tested the material only in rats and rabbits, but if it works just as well in humans, it could help patients to regenerate lost tissues without leaving scars or deformities.

They are able to restore some functions of the brain of a pig that had been dead for 4 hours
Let's start with punctualization to dose our optimism: it is not a living brain, but it is a cellularly active brain. Now we can say that, yes, in fact, researchers at Yale University have revived the brain of a pig hours after his death, when it is assumed that this is no longer possible.
The Mediterranean diet and scientific myths: this helps you lose weight and its health effects
The Mediterranean diet and scientific myths: this helps you lose weight and its health effects
The Mediterranean diet, today, is a seal of quality: it is used to denote how healthy a food is. And the truth is that, in its beginning, everything that protected the Mediterranean diet is healthier, in general terms. Now, however, the ambiguity of the term has allowed numerous products and habits that are far from the initial premise to slip.

Laboratory-grown blood vessels are given to people with kidney failure.
According to a new study, Humacyte, a technology company in Durham, North Carolina, has managed to grow blood vessels using human smooth muscle cells, which are found in arteries and veins. And, after this, it has successfully added these laboratory-grown blood vessels in the circulatory system of patients, this being more effective than the standard procedure, which is to use synthetic tubes to replace damaged blood vessels.
This is how your smartphone's camera can detect a form of cancer in your eyes
This is how your smartphone's camera can detect a form of cancer in your eyes
A common telephone camera can detect signs of retinoblastoma, an aggressive cancer that primarily affects children. It usually appears in the photos as a whitish glow in the pupil, which is often reflected in the light emitted by the camera's flash. While the brightness may occur for other reasons, the child should see a doctor for a full diagnosis if the brightness appears in the photo, since the diagnosis and treatment could save his vision, eye or life.
If you're looking to lose weight, focus your efforts on diet and not on physical exercise.
If you're looking to lose weight, focus your efforts on diet and not on physical exercise.
Losing weight is a slow and sometimes difficult task. Everyone goes through that phase at which we give all the importance to the exercise: "No matter what I eat, I will burn it in the gym." But this is a big mistake. Ensuring our diet is more important than exercising, even when it comes to losing the extra pounds.
