Model more accurately maps the impact of frost on corn crops
Publicado em 13 de fevereiro de 2026
Brazilian researchers have developed a methodology that uses remote sensing to map the impact of frost on corn crops. This reduces exposure to climate risks and uncertainty regarding agricultural losses.
The model allows users to customize a set of variables, making it useful for other crops in different agricultural contexts. Thus, it has the potential to provide more accurate estimates during harvests and contribute to the development of public policies that support production chains and [...]

Deforestation in the Amazon raises the surface temperature by 3 °C during the dry season
Publicado em 13 fevereiro 2026Deforestation in the Amazon is causing significant regional changes in climate compared to areas with forest cover above 80%. The loss of vegetation leads to an increase in surface temperature, a decrease in evapotranspiration, and a reduction in precipitation during the dry season and in the number of rainy days. The results are part of a study based on satellite data published in late November in the journal Communications Earth & Environment . The study points out that highly [...]ver notícia -
Parents’ alcohol and drug use influences their children’s consumption, research shows
Publicado em 13 fevereiro 2026“Like father, like son? Can parenting styles break the intergenerational pattern of alcohol and drug use?” A group of Brazilian researchers analyzed data on the behavior of 4,280 adolescents and their guardians based on this question, arriving at two important conclusions. Yes, parental attitudes are one of the most relevant factors in preventing alcohol and drug use among young people. However, the way guardians educate their children can significantly mitigate the risk, even in [...]ver notícia -
Pregnant women unaware of their rights and suffer violations in the workplace
Publicado em 12 fevereiro 2026Despite clear laws that guarantee the protection of pregnant women and new mothers in the workplace, many Brazilian women still experience a reality far from what is stipulated on paper. A study supported by FAPESP involving 652 women in the immediate postpartum period revealed that most are unaware of their labor rights during pregnancy and postpartum. More than half reported experiencing some type of workplace violation during this period. The results were published in BMC Pregnancy and [...]ver notícia -
Afraid of chemistry at school? It’s not all the subject’s fault
Publicado em 11 fevereiro 2026Raise your hand if you dreaded chemistry lessons at school. Apart from a few exceptional cases, this discipline is often perceived as difficult, abstract and removed from real life. This affects students’ motivation and choices, discouraging them from pursuing academic and professional careers in this important and, in fact, fascinating field. In a new article published in JCOM , a team of Brazilian researchers — Ariane Carolina da Rocha, Ana Carolina Steola and Ana Cláudia Kasseboehmer [...]ver notícia -
Brief, intensive exercise helps patients with panic disorder more than standard care
Publicado em 09 fevereiro 2026Panic attacks are sudden bouts of intense fear without an obvious cause. An estimated 10% of people experience at least one panic attack in their lifetime. But between 2% and 3% of the population have such frequent and severe panic attacks that they meet the criteria for the debilitating condition ‘panic disorder’. The current standard of care for panic disorder is cognitive behavioral therapy (CBT), with or without antidepressants. A technique of CBT with proven efficacy is [...]ver notícia -
Modulated UV-C light increases the shelf life of guavas, study shows
Publicado em 06 fevereiro 2026The application of modulated UV-C light to guavas – emitted in pulses or cycles rather than continuously – combated anthracnose. This fungal disease is caused by microorganisms belonging to the Colletotrichum gloeosporioides complex and triggers dark lesions on the fruit after harvest, reducing its shelf life. An article on the technique was published in the journal Horticulturae . The disease usually manifests on the skin but can reach the pulp through injuries caused by insects, [...]ver notícia -
Seabirds Ingest Large Quantities Of Pollutants, Some Of Which Have Been Banned For Decades
Publicado em 06 fevereiro 2026In her 1962 book, Silent Spring , American biologist Rachel Carson revealed that DDT, a widely used pesticide at the time, was responsible for the mass death of birds, including the iconic bald eagle. One reason was that the pesticide made eggshells thinner, causing mothers to break them when sitting on them to incubate. Silent Spring is considered the founding work of the modern environmental movement. Most rich countries had banned DDT by the 1970s. In Brazil, the agricultural ban did [...]ver notícia -
Model connects animal movement and population dynamics
Publicado em 05 fevereiro 2026For planning animal conservation measures, it is vital to know where endangered species live and how they interact. Ecologists are successfully using tracking technology to learn about the movements of individual animals. Yet, leveraging this knowledge to understand how entire populations change in space and time, including long-term persistence and survival chances in a given area, remains a long-standing open question in ecology. A major step toward answering this question was now achieved [...]ver notícia -
Almost half of the world’s aquatic environments are severely contaminated by waste
Publicado em 05 fevereiro 2026“Dirty” or “extremely dirty”: these are the classifications of 46% of the world’s aquatic environments. This conclusion comes from a study that compiled and systematized data from 6,049 records of waste contamination in aquatic environments on all continents over the last decade. The study, coordinated by researcher Ítalo Braga de Castro and led by doctoral student Victor Vasques Ribeiro from the Institute of Marine Science at the Federal University of São Paulo (IMar-UNIFESP) in [...]ver notícia
