New study finds another key to longevity: It's in the gut
Transferring gut bacteria from aged mice to young mice resulted in increased neurogenesis. Thanks to the butyrate produced in the intestine.

Rapamycin slows down skin aging: first studies in humans.
Rapamycin continues to amaze: after having slowed down the aging of mice and other species, in the first study on human tissues it also shows that it counteracts skin aging. And it's just the beginning.
Help, now quadruped robots also go up the ladders
The application of neural networks and opposable "thumbs" allows quadrupedal robots to overcome their biological counterparts and even climb vertical ladders
Copper beds kill 95% of bacteria: they can save millions of lives
In 2018 alone, hospital infections killed 49.000 people in Italy. lives that can be saved, says a study, with copper beds in hospitals
Obtained the most detailed human brain scan ever
1000 times more accurate than an MRI: the scan of the human brain just obtained in Massachusetts is a milestone.
The secret of breast milk discovered: it is GML. In other types of milk? Absent
Immunizes children from asthma, allergies and more. Without him, breast milk does not work, and in other types of milk it is practically not there. Here is the GML.
Does weightlessness kill cancer cells?
A group of researchers plans to send cancer cells into space after research in a microgravity environment showed notable effects.
Really: how many chances do we have to live forever?
The prospect of living forever exalts many, terrifies many. What weight does this aspiration and this fear have? The answer of 4 scientists.
Developed metal that repairs itself at room temperature
For 6000 years we have made objects out of metal because it is strong and resistant: it takes a lot of energy to break it. The problem is that it takes a lot of energy to even repair it. You need a blowtorch that heats the metal parts up to 3500°C. Today, for the first time in the world, a research team has developed a way to repair metal at room temperature. A "regeneration" completely similar to the repair process of our bones, which will lead to the birth of... Read more
Startup in Mexico purifies the air with artificial trees
BioUrban 2.0 artificial trees can make a difference in areas traveled by pedestrians, cyclists or the elderly, where planting trees is not possible.
Aerium, bioavionics will make airplanes living organisms
Bioavionics integrates biological and electromechanical systems to see how their interaction will change our flight experiences.
Dragonfly is official, NASA will make a mission on Titan
Dragonfly will land near Titan's equator, among dunes apparently composed of layers of solid hydrocarbons. It will be powered by plutonium like the Martian rovers, and with its eight rotors it will be able to cover much more distance than any space predecessor.
Glucose-powered artificial muscles such as humans
The artificial muscles developed by the Linköping University team are made of polymeric material into which enzymes have been introduced: a solution of oxygen and glucose in water powers the actuators, just as happens in human muscles.
eNAMPT, enzyme in the blood of young mice extends the life of elderly ones: now tests on humans
As reported in the journal Cell Metabolism, the protein circulating in mice (an enzyme called eNAMPT) plays a key role in the process that provides cells with energy. Over the years, the latter become less and less efficient in producing this "fuel" (called NAD) necessary for your health.
Modern Meadow, a journey to the origins of vegan leather jackets
Interest is growing in this challenge that intersects biology, design, fashion and respect for animals and nature.
Rapamycin, portrait of the miracle drug that reverses aging
Here's how the effects of rapamycin unfold, and why its use in commercial products can lead to an extension of life expectancy.
Synthetic blood: in 2024 the first uses
Since 1600 man has been looking for an effective substitute for blood, the most important vehicle of oxygen in our body. Let's retrace all the stages of an infinite journey and the first exciting results available within the next 5 years.
Mice were born without a "mom"
It is always said that fathers are no longer useful, that children can now be conceived even without a man, but apparently this time science has made further progress. In fact, the first #mice were born from embryos formed without the need for sperm and egg to come into contact. The study, published in the journal Nature Communication, shows how the sperm did not fertilize the egg cell but 'drafts' of embryos. The great result was obtained at the British University of Bath, … Read more
What is life? Venter promises a new human evolution
“What is life?” asks Craig Venter, the man who first mapped the human genome and created the first cell with a synthetic genome. “Just 3 letters are enough to compose a universe of questions still unanswered. What separates the animate from the inanimate? What are the basic ingredients of life? Who lit the first spark? How did the first organism evolve? How extensive is life in the universe? If other types of creatures exist on other planets, they are intelligent… Read more
Blood nanorobot to treat infections and tumors
This is the case of "nanobots" or microscopic machines (about 50 nanometers in size) that science fiction had imagined in the Star Trek series and which, injected into a patient's circulation, went there to rebuild damaged tissues, eliminate pathogens such as viruses and resistant bacteria or even eradicate a cancer. Unfortunately, the economic factor often stops the ideas and drive towards innovation of motivated researchers: no one puts in the money and the research remains on paper. … Read more
Synthetic organ made 'from scratch' with stem cells.
If you are still not convinced that stem cells are the future of medicine, listen here: a group of Japanese researchers used stem cells to synthesize a new, fully functional organ in the laboratory, starting from SCRATCH. This is the research team at the RIKEN Center for Developmental Biology, which took mouse stem cells and transformed them into a perfectly functioning pituitary gland: the pituitary gland, otherwise called the pituitary gland, is a small organ...
