Planning space missions takes a large amount of time and effort because travelling through space is extremely expensive. Scientists always look for routes that use less fuel, as even small improvements in efficiency can save millions of dollars, reported Space.com. An international team of researchers says it has discovered a more efficient route between Earth and the moon using advanced computer modelling. The researchers developed the method using the theory of functional connections, [...]

An international team of scientists published research in April 2026 in the journal Astrodynamics on a fuel-saving Earth-to-Moon trajectory. The study involved researchers from the University of São Paulo in Brazil and the University of Coimbra in Portugal. The lead author was Allan Kardec de Almeida Júnior, and Vitor Martins de Oliveira was a co-author. Earth-Moon Transfer Trajectories Earth-to-Moon travel uses transfer trajectories that are calculated with orbital mechanics and [...]

The Sabia virus has been circulating in Brazil for over a century and evolving genetically, which has reduced the accuracy of older diagnostic tests and highlights the need for updated surveillance tools. The Sabia virus has been circulating in Brazil for around 142 years and continues to undergo genetic changes, according to a new study published in PLOS Neglected Tropical Diseases. The virus, which causes an acute hemorrhagic and neurological syndrome, has been linked to four fatal cases [...]

Major fossil rethink: Scientists found that supposed early animal traces in Brazil are actually fossilised bacteria and algae, reshaping theories on early life. High-tech investigation: Micro- and nanotomography plus Raman spectroscopy revealed preserved cells and organic matter, ruling out simple sediment disturbances. Timeline implications: The discovery suggests small animals may have appeared later than thought, as Ediacaran oceans possibly lacked enough oxygen for them. Fossils [...]

Fossils that were previously seen as traces of the earliest forms of tiny animals were actually communities of algae and bacteria, a new study has claimed. Researchers who studied the microfossils in Brazil found they had cellular structures like those found in microorganisms. Earlier studies had suggested that these structures may have been ancient wormlike creatures or marine animals from the Ediacaran period. What is the study? “We observed that the microfossils have cellular [...]

Researchers at the São Carlos Institute of Physics at the University of São Paulo (IFSC-USP) in Brazil, led by Paulo Augusto Raymundo-Pereira, have created biodegradable, “wearable” sensors for plants to monitor their health, including the presence of pesticides. The sensors are made from carbon ink and are screen-printed onto transparent cellulose acetate bioplastics. The study was published in Biosensors and Bioelectronics: X. The World Economic Forum selected wearable sensor [...]

New Delhi: Researchers in Brazil have unveiled a ground-breaking technique that uses high-frequency ultrasound waves to destroy viruses by causing them to rupture from within, a process scientists have compared to popcorn exploding under heat. The discovery, made by researchers at the University of São Paulo, could open a new frontier in anti-viral treatment by targeting the physical structure of viruses rather than their genetic makeup. The study, published in the journal Scientific [...]

For years, scientists believed strange microscopic patterns preserved in ancient Brazilian rocks were the evidence that tiny animals had already started moving across the seafloor over half a billion years ago. But a new fossil reanalysis is currently overturning that interpretation and focusing on to a very different comprehension: the structures were likely created by microbial life, not animals. The study, published in Gondwana Research, analyzed fossils dating back roughly 540 million [...]
