Pediatric Investigation Review Discusses the Challenges, Innovations, and Future Directions in Dengue Vaccine Development
Publicado em 30 de maio de 2025
The review details the historical and current status of dengue vaccine development, underscoring key themes of future research
Dengue fever caused by a flavivirus named DENV is a major global health challenge, risking almost half of the world’s population. Since the early 20th century, the scientific community has faced multiple challenges to develop effective dengue vaccines. This spanned a variety of techniques – from the use of ox bile to weaken DENV to the chemical [...]

Stirling Research Could Extend Biopesticide Effectiveness
Publicado em 27 maio 2025Changes to a pest’s diet could slow the evolution of resistance to biopesticides, according to research from University of Stirling scientists. It is hoped that the findings could allow the development of biopesticides that are effective for longer, potentially increasing food security, reducing damage to the natural environment and boosting agro-ecological biodiversity. Researchers discovered that cotton bollworm pests – a species of moth that can cause considerable [...]ver notícia -
Global Study Links Consumption of Ultraprocessed Foods to Preventable Premature Deaths
Publicado em 21 abril 2025A study analyzing data from nationally representative dietary surveys and mortality data from eight countries (Australia, Brazil, Canada, Chile, Colombia, Mexico, United Kingdom, and United States) shows that premature deaths attributable to consumption of ultraprocessed foods (UPFs) increase significantly according to their share in individuals’ total energy intake. The new study, appearing in the American Journal of Preventive Medicine, published by Elsevier, reinforces the call for [...]ver notícia -
Aerobic exercise: a powerful ally in the fight against Alzheimer’s
Publicado em 16 janeiro 2025Regular aerobic exercise could significantly reduce disease markers associated with Alzheimer’s, new research led by scientists at the University of Bristol (UK) and the Federal University of São Paulo (Brazil) has found. The findings provide new hope in the battle against this devastating disorder. Published in the journal Brain Research, the study highlights how physical activity not only protects healthy brain cells but also restores balance in the aging brain. The [...]ver notícia -
SCIENCE Publikation: Ameisen betreiben Landwirtschaft – seit 66 Millionen Jahren
Publicado em 17 outubro 2024(openPR) Nicht nur Menschen betreiben Landwirtschaft – Ameisen beherrschen diese Kunst schon viel länger. Sie bauen Pilze an. Und das seit 66 Millionen Jahren, wie Forschende mit Beteiligung der Universität Hohenheim in Stuttgart herausgefunden haben. Möglich wurde dies durch Gensequenzierung, aus der sich ein Stammbaum der Pilze ableiten ließ. Kombiniert mit dem Stammbaum der Ameisen konnten die Forschenden eine Jahrmillionen dauernde Koevolution belegen, bei der [...]ver notícia -
Colonial legacy: Goethe University Frankfurt researches international project on land use conflicts in West Africa
Publicado em 24 julho 2024FRANKFURT. During the German and French colonial period, at the end of the 19th to the middle of the 20th century, around 50,000 farmers from the Kabyè ethnic group were forcibly resettled from the densely populated north to the sparsely populated south in what are now the West African states of Togo and Benin. Whereas the German colonial power needed workers to build transport routes, the French government wanted to develop the region for agriculture. To this day, however, farming is [...]ver notícia -
El proyecto del Biogenoma de la Tierra secuenciará el genoma de cerca de 40.000 especies de plantas, animales y hongos de los Países Catalanes
Publicado em 18 julho 2024La pérdida de la biodiversidad es una de las amenazas más alarmantes a las que se enfrenta el planeta. Hábitats degradados, recursos sobreexplotados, crisis climática y especies invasoras son algunos factores que ponen en riesgo la riqueza y la variedad de especies de seres vivos. La desaparición rápida y progresiva de organismos —algunos expertos hablan de una sexta extinción masiva— creará grandes desequilibrios en los [...]ver notícia -
Obtaining hydrogen from vine shoots for biofuel production
Publicado em 15 janeiro 2024A research team from the universities of Jaén and São Paulo in Brazil has confirmed that hydrogen can be obtained from vine shoots through a process that does not require fossil fuels nor emits pollutants. With their work they manage to give new value to this waste from the wine industry, while creating environmentally friendly energy. Almost 93% of the residues produced during the grape harvest are made up of debris, i.e. vine shoots, which until [...]ver notícia -

Agriculture needs fresh approach to tackle insect resistance to biopesticides, new analysis finds
Publicado emInsect pests which attack crops have extraordinary powers to develop resistance to greener pesticides and a new way to manage resistance risks is needed, according to analysis by University of Stirling scientists. For more than 70 years, agriculture’s response to pesticide resistance has been to seek new pesticides in an endless race to keep up with evolving pests. Researchers now propose a new way to step off this treadmill as farmers embrace the ongoing green revolution in pest [...]ver notícia
