A smarter way to build vaccines: UTMB scientists harness AI to target emerging alphaviruses
Publicado em 09 de abril de 2026
A team of scientists at The University of Texas Medical Branch (UTMB), led by Nikos Vasilakis, PhD, and Peter McCaffrey, MD, has developed a new computational pipeline that could dramatically accelerate the development of vaccines against a group of mosquito-borne viruses known as alphavirus
Vasilakis is a professor and the vice chair for research, and McCaffrey is an assistant professor of clinical practice and director of the UTMB AI center, both in the Department of Pathology. The work [...]

China's science foundation issues guidelines for international cooperation on sustainable development
Publicado em 02 abril 2026BEIJING, April 2 -- The National Natural Science Foundation of China (NSFC) released guidelines for the Sustainable Development International Cooperation Program (SDIC) in 2026, which involves multiple international partner organizations and covers areas such as life and health, green resources, and climate change. According to the guidelines issued on Wednesday, this year's SDIC will focus on key challenges in global sustainable development, combining common challenges with global [...]ver notícia -
Ocean Chemistry Now Substantially Shaped by Humans
Publicado emAlthough the oceans are the least explored places on the planet, even their depths are not untouched by humans. Drawing on more than 2,300 seawater samples collected across the Pacific, Atlantic and Indian Oceans, researchers found that hundreds of synthetic chemicals - many of them rarely monitored and originating from everyday products - are now woven into the fabric of marine organic matter. The findings, published in Nature Geoscience, suggest that industrial and consumer compounds [...]ver notícia -
Coastal ocean chemistry now substantially shaped by humans
Publicado emA global analysis of more than 2,300 seawater samples from more than 20 field studies around the globe indicates that human-made chemicals make up a significant portion of organic matter in coastal oceans. The international study, led by biochemists Jarmo Kalinski and Daniel Petras at the University of California, Riverside, analyzed seawater samples collected over a decade from coastal regions from the Pacific, Atlantic, and Indian Oceans. Reported in Nature Geoscience, the findings show [...]ver notícia -
How food shortages reprogram immune system response
Publicado em 10 fevereiro 2026When food is scarce, stress hormones direct the immune system to operate in "low power" mode to preserve immune function while conserving energy, according to researchers at Weill Cornell Medicine. This reconfiguration is crucial to combating infections amid food insecurity. "Both famine and infectious disease have been with us throughout our evolutionary history and often occurred at the same time. Yet little is known about how nutrition affects the immune system," said senior author [...]ver notícia -
Genetic study shows: Anxiety disorders have many causes
Publicado em 05 fevereiro 2026The largest genetic study on anxiety disorders to date reveals new biological mechanisms behind anxiety. It can help to find new ways to develop more precise therapies. Around one in four people suffer from an anxiety disorder at some point in their lives. These include panic disorder with sudden, severe anxiety attacks, generalised anxiety disorder, in which sufferers worry about everyday things over a longer period of time that is difficult to control, and phobias of specific objects or [...]ver notícia -
Pesquisa revela regiões ideais do genoma do milho para criação de plantas transgênicas
Publicado em 12 janeiro 2026A identificação de "portos seguros" no genoma do milho abre caminho para acelerar, baratear e tornar mais preciso o desenvolvimento de cultivares. Um estudo liderado por pesquisadores da Unidade Mista de Pesquisa em Genômica Aplicada a Mudanças Climáticas - UMiP GenClima/GCCRC apresenta um panorama inédito das tecnologias mais promissoras para inserir genes de forma precisa no genoma de plantas, especialmente no milho. A revisão, realizada em parceria com o Centro de Biologia [...]ver notícia -
Tools of Change: Researchers Uncover Ancient Tech Tradition
Publicado em 07 novembro 2025New research led by Anthropology's David Braun revealed how early humans crafted stone tools for nearly 300,000 years during dramatic environmental upheaval. Led by GW researchers, an international team of scientists uncovered evidence of stool tools dating from 2.75 to 2.44 million years ago at a site in Kenya's Turkana Basin. (Photos Courtesy Koobi Fora Research and Training Program) Imagine early humans meticulously crafting stone tools for nearly 300,000 years-all while [...]ver notícia -
MIT joins in constructing the Giant Magellan Telescope
Publicado em 30 setembro 2025The following article is adapted from a joint press release issued today by MIT and the Giant Magellan Telescope. MIT is lending its support to the Giant Magellan Telescope, joining the international consortium to advance the $2.6 billion observatory in Chile. The Institute's participation, enabled by a transformational gift from philanthropists Phillip (Terry) Ragon '72 and Susan Ragon, adds to the momentum to construct the Giant Magellan Telescope, whose 25.4-meter aperture will [...]ver notícia -
AI Reveals Astrocytes Play a 'Starring' Role in Dynamic Brain Function
Publicado em 08 julho 2025Long overlooked and underestimated, glial cells - non-neuronal cells that support, protect and communicate with neurons - are finally stepping into the neuroscience spotlight. A new Florida Atlantic University study highlights the surprising influence of a particular glial cell, revealing that it plays a much more active and dynamic role in brain function than previously thought. Using sophisticated computational modeling and machine learning, researchers discovered how astrocytes, a [...]ver notícia
