A group of researchers from the State University of Campinas (UNICAMP) in the state of São Paulo, Brazil, developed a product made from native bee honey and cocoa bean shells that can be consumed directly or used as an ingredient in food and cosmetics. Cocoa bean shells contain theobromine and caffeine, which can be transferred to honey from stingless bees using ultrasound-assisted extraction.

Insects that feed on starch can find veritable feasts in corn, pea, and bean crops or warehouses. It is no coincidence that the ancestors of these commercial plants developed α-amylase (alpha-amylase) inhibitor proteins, which make the starch in their seeds indigestible to pests, keeping them from becoming serious threats. However, the domestication of wild plants by humans to increase productivity and digestibility may have reduced the presence of these inhibitors. In an article, an [...]

Vivir diariamente con dolor crónico es una experiencia que afecta no solo el cuerpo, sino también la mente y las emociones. Esa es la realidad de miles de personas que padecen disfunción temporomandibular (DTM), una condición que afecta la articulación responsable de abrir y cerrar la boca, además de los músculos de la masticación. Para estas personas, los dolores constantes en la mandíbula, las sienes, el rostro o alrededor del [...]

Living with chronic pain on a daily basis impacts not only the body but also the mind and emotions. This is the reality for thousands of people with temporomandibular disorder (TMD), a condition affecting the joint responsible for opening and closing the mouth, as well as the chewing muscles. For these individuals, constant jaw, temple, facial, or ear pain; difficulty chewing; and headaches can affect their daily routine and mental health. A study conducted at the Ribeirão Preto [...]

A study led by researchers from the Center for Innovation in New Energies (CINE) has shown that replacing water with glycerol – popularly known as glycerin – increases the efficiency of photoelectrochemical cells. These cells use sunlight as a source of clean, renewable energy to generate green hydrogen. CINE is an Applied Research Center (ARC) set up by FAPESP and Shell in 2018. It is based at the State University of Campinas (UNICAMP), the University of [...]

A study showed that a fraction obtained from lignin, an organic polymer responsible for the rigidity of plant cell walls, was able to improve the performance of nanoparticles with herbicide. The study was conducted by researchers from three research institutions in the state of São Paulo, Brazil: São Paulo State University (UNESP), the State University of Campinas (UNICAMP), and the Federal University of São Carlos (UFSCar). "Lignin has antioxidant properties and [...]

Brazilian researchers have developed a low-cost, portable biosensor that can quickly identify a protein whose altered levels are associated with psychiatric disorders, such as depression, schizophrenia, and bipolar disorder. When it becomes commercially available in the future, it may contribute to early detection, which is essential for treating and monitoring patients' clinical conditions. The biosensor is the result of a partnership between researchers at the University of São [...]

A study recreated in the laboratory chemical reactions that may have occurred on Earth about 4 billion years ago, producing the first molecular precursors for the emergence of life. Champagne hydrothermal vent in the Pacific Ocean: Although the study focused on basic science, the approach also inspires technological applications in electrocatalysis and hydrogen production.

A team of researchers from the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, has developed a sensor that can identify sodium nitrite (NaNO2) in various beverages, including mineral water, orange juice, and wine. This inorganic salt is used as a preservative and fixative to give products such as ham, bacon, and sausages their pink or red color. Depending on the amount, it can cause serious health problems by leading to the formation of [...]
