With the challenge of reducing atmospheric carbon dioxide, a tower with microalgae filters has been designed that generates healthy air in the middle of cities.

These are some towers called BIOURBAN, which have a biofiltration system of atmospheric pollutants that improve air quality, as if they were artificial trees.

The invention is the work of the team of the young Mexican Carlos Monroy Sampieri. Its startup Biomitech was the winner of the Heineken Green Challenge ...

Five people infected with HIV who received a stem cell transplant now have the virus undetectable in blood and tissues. In one of them, researchers cannot even detect antibodies in their blood. This finding could be useful for the design of new strategies to cure the infection.

The viral reservoir, made up of cells infected by the virus that remain dormant and cannot be detected or destroyed by ...

  • Researchers have identified the anatomical structure from new fibers
  • These were usually discarded in anatomical dissections

Researchers at the University of Barcelona (UB) have discovered a new anatomical structure of the human ankle with the identification of new fibers, usually discarded in anatomical dissections, which are actually a new ligament in the lateral part of the ankle.

These results, published in the scientific journal Knee Surgery, Sports Traumatology, Arthroscopy, change the understanding of this articulation and could explain ...

A team led by the University of Barcelona has designed the first photopharmaceutical with therapeutic potential to fight against Parkinson’s. The compound, which is activated by light from the visible spectrum, has been tested in animal models. According to the authors, photosensitive drugs can act with greater spatial and temporal precision without generating harmful effects in the organism.

A retinal implant slows blindness caused by macular degeneration

According to the authors, the stem cells of the implant were successfully integrated with the tissue and the retina showed anatomical changes consistent with the reappearance of the pigmentary epithelium / Kashani et al.

A US scientific team has created a device with human embryonic stem cells to treat macular degeneration associated with age. The artificial tissue, tested on four people suffering from the disease at an advanced stage, stopped the loss of vision. One of the patients managed to read ...

A new advanced computer system unifies the information of the possible biomarkers of pancreatic cancer, optimizing its detection. The main problem posed by this tumor is its late diagnosis, since in 80% of cases the disease is identified when patients are already in a very advanced or metastatic state.

A multidisciplinary team of scientists from the departments of Architecture and Computer Technology and Anatomy and Human Embryology ...

Discovered a fundamental mechanism to repair damaged nerves

Unlike what happens with the spinal cord after an injury, the peripheral nerves – which innervate the muscles and make their movement possible have a significant ability to ‘self-repair’. However, it is a slow process that can fail and leave sequels. Neurosciences Institute of Alicante have taken an important step to facilitate this repair process.

After an injury, the final part of the peripheral nerves undergoes a specialized biological ...

Spanish researchers have developed a strategy based on biomaterials and therapeutic proteins to regenerate bones. The results, published in Drug Delivery, have been tested in experimental models in order to enhance the reparative response of bone morphogenetic protein 2 and increase the rate of bone mineralization.

Scientists from the Center for Applied Medical Research (CIMA) ...

Robert Hooke

Formed at the University of Oxford, Robert Hooke collaborated in the heart of this institution with the British chemist Robert Boyle in the construction of an air pump (1655). Five years later he formulated the law of elasticity that bears his name (Hooke’s law), which establishes the direct proportional relationship between the stretch suffered by a solid body and the force applied to produce that stretch.

Hooke formulated this law as a result of his experiences, in ...

Discoverer of the vaccine against cholera Jaime Ferrán Clúa

Jaime Ferrán Clúa was born on February 1, 1951 in Corbera de Ebro and died in Barcelona on November 22, 1929, this internationally recognized bacteriologist was one of the first discoverers of a vaccine against cholera and then another against tuberculosis.
He was the son of the village doctor and graduated in Medicine in Barcelona in 1873. He went on to practice as a doctor in Pal del Panadés. By then he had explored the fields of photography, painting and ...
