Biological nanofibrils effectively extract precious metals from water
A new system could greatly simplify access to precious metals that are essential for many modern industrial processes and appliances.
A simple chemical reaction recycles polystyrene into more 'noble' products
UV light and aluminum chloride as a catalyst can break down polystyrene into a chemical used in perfumes and medicines.
A bioengineered cornea can restore sight to the blind and visually impaired
A team of researchers and entrepreneurs has developed an implant, made from pig skin, that mimics the human cornea: it works great
An 'artificial blood' repairs damaged organs hours after the heart stops
Artificial blood can repair cell damage caused by lack of oxygen. It could make transplants easier, treat heart attacks and strokes, and even reverse cell death.
"Resuscitate" pig cells dead for an hour: possible turning point for transplants
Pig cells today, but tomorrow this experimental technique could preserve human organs destined for donation
Transforming dead spiders into robots: a few words on necrobotics
A new field of study known as "necrobotics" is born. Researchers used dead spiders to grab objects
More and more sugary foods and drinks, a serious problem
According to a study published by Cambridge, over the past 10 years there has been an ever-increasing use of added sugars and non-nutritive sweeteners in the production of packaged foods.
Humans may not be able to withstand all this heat
If true, millions more people could be at risk from heat waves and dangerously high temperatures.
The new GMO rice flexes its muscles: 40% more grains
A new genetic modification can increase photosynthesis and uptake of fertilizers in rice, wheat and other crops. The effect is a 40% higher yield with reduced curing times.
A new fat-burning molecule increases the energy consumption of fat cells
A molecule identified in mice, purine inosin, which stimulates fat burning in brown adipocytes. Human tests are near.
The aerosol that is forming over the Arctic has effects on the world climate
Aerosols (and clouds) forming in the Arctic produce effects on the rest of the planet: here are the efforts to understand which and how many are
Big step forward in the manufacture of a "biohybrid" artificial heart
Harvard bioengineers developed the first biohybrid model of a human ventricle with beating and aligned heart cells.
These high-density batteries withstand extreme temperatures, hot and cold
The University of California develops high-density batteries that withstand very hot and very cold temperatures without batting an eye.
DNA from an ancient ice age wolf reveals the origins of the domestic dog
A study by some geneticists and archaeologists has shown that the lineage of man's best friend, the dog, can be traced back to at least two specific populations of ancient wolves. Finally we will be able to find out how (and where) we went from the wild wolf to the domesticated dog.
We know how to repair and regenerate heart muscle cells
The discovery of a mechanism to repair the heart muscle has the potential to revolutionize heart treatments and cures
A polystyrene-eating "super worm" can help us dispose of waste
All over the world it is hunting for bacteria and insects that consume waste to dispose of it. The last one? A "super" worm hungry for polystyrene.
Monkeypox: let's orient ourselves with 4 answers to 4 questions
Over 300 infections in 21 countries outside Africa. Should we worry? How fast is its spread? We assess the situation
Rectal cancer, new drug eliminates it without chemo or surgery
First phase of testing for a new drug based on monoclonal antibodies: rectal cancer "totally eliminated" in 100% of patients.
A photonic processor (really) recognizes billions of images per second
A 'photonic' chip, which uses light to process, is able to recognize billions of (small) images per second.
