The Giant Magellan Telescope will be one of the few super giant earth-based telescopes that promises to revolutionize our view and understanding of the universe. It will be constructed at the Las Campanas Observatory in Chile. Commissioning of the telescope is scheduled to begin in 2021. The GMT is a segmented mirror telescope that employs seven of today’s largest stiff monolithic mirrors as segments. Six off-axis 8.4 meter segments surround a central on-axis segment, forming a [...]

Food engineers in Brazil and France developed gels based on modified starch for use as “ink” to make foods and novel materials by additive manufacturing. It is already possible to produce food with a 3D printer, potentially delivering products that suit consumer preferences regarding taste, texture, cost, convenience, and nutrition. In the near future, it will be possible to produce food with personalized shapes, textures, flavors, and colors considered attractive and healthy for [...]

Dreams during the COVID-19 pandemic lockdown reflect mental suffering (anger, sadness) and fear of contagion, according to a new Brazilian study. Are dream reports from the Covid-19 pandemic period different from dream reports prior to the pandemic?. (A) Data collection timeline (audio recordings of dreams reported via smartphone application), and illustrative examples of two translated dream reports by the same participant, one before and one after the Covid-19 pandemic. Words in [...]

Monoclonal antibody tested by researchers at University of São Paulo and experimental drug given to patients in Italy by University of Pennsylvania research group promoted rapid improvement of respiratory function in patients in severe condition. Two independent clinical studies – one by researchers at the Center for Cell-Based Therapy (CTC) in Ribeirão Preto, state of São Paulo (Brazil), on the monoclonal antibody eculizumab, and the other by scientists at the [...]

Brazilian researchers discover that caecilians, limbless amphibians resembling worms or snakes that emerged some 150 million years before the latter, can probably inject venom into their prey while biting. A group led by researchers at Butantan Institute in Brazil and supported by FAPESP has described for the first time the presence of venom glands in the mouth of an amphibian. The legless animal is a caecilian and lives underground. It has tooth-related glands that, when compressed during [...]

Researchers isolated molecules present in the larvae of a blue light-emitting fungus gnat that inhabits the Appalachians; the study will help elucidate human diseases and could lead to novel biotech applications. Molecules belonging to an almost unknown bioluminescent system found in larvae of the fungus gnat Orfelia fulton i (subfamily Keroplatinae) have been isolated for the first time by researchers at the Federal University of São Carlos (UFSCar) in the state of São Paulo, [...]

The process occurs in active-core nuclei. A molecular gas cloud that accumulates in the central region is blown away by radiation from the black hole’s accretion disk, forming a huge expanding hot bubble, whose radius can reach 300 light years. Black holes can expel a thousand times more matter than they capture. The mechanism that governs both ejection and capture is the accretion disk, a vast mass of gas and dust spiraling around the black hole at extremely high speeds. The disk is hot [...]

The lens can be used to produce high-resolution images with a wide field of view. It can serve as a camera lens in smartphones and can be used in other devices that depend on sensors (high resolution wide angle selfie obtained using metalens. A lens that is a thousand times thinner than a human hair has been developed in Brazil by researchers at the University of São Paulo’s São Carlos School of Engineering (EESC-USP). It can serve as a camera lens in smartphones or be used [...]

Brazilian researchers used genetic engineering to develop a low-cost platform for the production of enzymes that break down sugarcane trash and bagasse for conversion into biofuel. The novel molecules have many potential industrial applications. Researchers at the Brazilian Center for Research in Energy and Materials (CNPEM) have genetically engineered a fungus to produce a cocktail of enzymes that break down the carbohydrates in biomass, such as sugarcane trash (tops and leaves) and bagasse, [...]
