Scientists Destroy COVID And Flu Viruses in The Lab With Sound Waves
Publicado em 11 de maio de 2026
Sound waves already used in medical scans may have a surprising new target: Viruses.
In lab experiments, scientists have demonstrated how ultrasound blasts can break down influenza A (H1N1) and SARS-CoV-2, which causes COVID-19.
Microscopic vibrations caused by ultrasound waves are sufficient to rupture the membranes surrounding their viral particles, experiments showed, rendering the viruses inactive.
The research was led by a team from the University of São Paulo in Brazil and could [...]

New Long-Necked Dinosaur Found in Brazil
Publicado em 07 maio 2026A study published in the Journal of Systematic Palaeontology describes a new species of dinosaur discovered during construction of a road-rail terminal in the city of Davinópolis in the state of Maranhão, in the Northeast of Brazil. The animal, named Dasosaurus tocantinensis, was approximately 20 meters long and lived about 120 million years ago. From an evolutionary perspective, its closest known relative lived in what is now Spain. The discovery indicates not only the presence of a [...]Mirage News (Austrália) -
A simple vitamin could help breast cancer treatment work better
Publicado em 06 maio 2026Breast cancer is one of the most common cancers affecting women around the world. Many women go through chemotherapy as part of their treatment. Chemotherapy uses strong drugs to kill cancer cells, but it does not always work the same way for every patient. Some tumors shrink completely, while others do not respond as well. Because of this, scientists are always looking for safe and simple ways to improve how chemotherapy works. A recent study from researchers in Brazil has offered new [...]KSR - knowRidge Science Report (Austrália) -
Small dose of antibiotic could help treat panic attacks
Publicado em 05 maio 2026Panic attacks can feel overwhelming and out of control. People who experience them often describe a sudden wave of fear, along with physical symptoms like a fast heartbeat, shortness of breath, and dizziness. These attacks can happen without warning and can make everyday life very difficult. Although there are medications available, they do not work for everyone and can sometimes cause unwanted side effects. A new study suggests that a simple antibiotic may help. Researchers from São [...]KSR - knowRidge Science Report (Austrália) -
An Existing Drug Could Be Repurposed to Help Treat Panic Attacks
Publicado em 05 maio 2026When a panic attack hits, it can be a scary, overwhelming, debilitating experience – but an effective new treatment could be on the way, in the form of an antibiotic. It's already known that carbon dioxide (CO 2) can induce panic attacks, as the brain senses signs of suffocation, and that brain immune cells known as microglia could be involved in triggering the emergency response. That's where minocycline comes in. It's a common antibiotic with effects that include reducing [...]ScienceAlert (Austrália) -
UFSCar Pioneers Sustainable Electrosynthesis of Amines from Air Nitrogen with FAPESP Funding
Publicado em 05 maio 2026Revolutionary Breakthrough at UFSCar: Sustainable Electrosynthesis of Amines from Air Nitrogen In a groundbreaking advancement for green chemistry, researchers at the Federal University of São Carlos (UFSCar) have developed a sustainable electrosynthesis method to produce valuable amines directly from atmospheric nitrogen. This innovation, supported by the São Paulo Research Foundation (FAPESP), promises to transform how Brazil's chemical industry approaches nitrogen fixation, [...]Academic Jobs (Austrália) -
Atmospheric Systems Drive African Rainfall to Amazon
Publicado em 04 maio 2026How are cold air masses advancing in the United States connected to fertilizers carried by "flying rivers" from Africa that nourish the soils of the Brazilian Amazon? An article published in Geophysical Research Letters reveals an atmospheric connection between these distant regions. Scientists discovered that synoptic systems – large-scale meteorological phenomena spanning thousands of kilometers – such as cold waves in the U.S. and high-pressure anomalies in the South Atlantic, [...]Mirage News (Austrália) -
Cheap Material Compresses Light, Boosts Photonic Circuits
Publicado em 04 maio 2026A two-dimensional lamellar crystal composed of atomically thin layers of lead iodide (PbI₂) could be used to manufacture a new generation of circuits that use light and mechanical vibrations (rather than electrons) to transmit information in the terahertz frequency range. This promising technology was studied by researchers at the Brazilian Center for Research in Energy and Materials (CNPEM), in partnership with colleagues from the University of Lille (France) and other international [...]Mirage News (Austrália) -
Common vitamin shows potential to reshape breast cancer treatment response
Publicado em 03 maio 2026According to research published in Nutrition and Cancer, a team at São Paulo State University investigated whether vitamin D supplementation could support chemotherapy in breast cancer patients. The study, backed by FAPESP, followed 80 women aged over 45 undergoing pre-surgical chemotherapy at a teaching hospital in Brazil. Instead of focusing solely on clinical outcomes, the researchers also underscored the accessibility of the intervention, noting that many therapies designed to [...]MSN (Austrália) -
Estudo da Unesp Revela: Minociclina em Baixa Dose Reduz Crises de Pânico
Publicado em 03 maio 2026A recente publicação na revista Translational Psychiatry marca um avanço significativo na pesquisa brasileira sobre transtornos de ansiedade, com a Universidade Estadual Paulista (Unesp) liderando um estudo inovador que explora o uso de doses baixas de minociclina para reduzir crises de pânico. Este trabalho translational, que combina experimentos em camundongos e testes clínicos em humanos, destaca o potencial anti-inflamatório do antibiótico como uma alternativa aos tratamentos [...]Academic Jobs (Austrália)
