Brigham researchers are working on a new approach to target autoimmunity in the brain leverages designer bacteria to make treatment safer and more effective
Researchers from Brigham and Women's Hospital, a founding member of the Mass General Brigham healthcare system, have designed a probiotic to suppress autoimmunity in the brain, which occurs when the immune system attacks the cells of the central nervous system. Autoimmunity in the brain is at the core of several diseases, including [...]

Study leads to milestone advances in understanding lethal bronzing of palm trees
Publicado em 31 maio 2023FULL STORY Palm trees infected with lethal bronzing disease emit signals that warn nearby healthy palms of the threat. Those healthy palms produce their own defense that University of Florida scientists one day hope to harness to protect palms against the disease. Entomologist Brian Bahder and his team at UF/IFAS Fort Lauderdale Research and Education Center (UF/IFAS FLREC) consider the study's outcome a turning point for palm disease research because it has high potential for [...]ver notícia -
Study links poor diet to 14 million cases of type 2 diabetes globally
Publicado em 17 abril 2023A research model of dietary intake in 184 countries, developed by researchers at the Friedman School of Nutrition Science and Policy at Tufts University, estimates that poor diet contributed to over 14.1 million cases of type 2 diabetes in 2018, representing over 70% of new diagnoses globally. The analysis, which looked at data from 1990 and 2018, provides valuable insight into which dietary factors are driving type 2 diabetes burden by world region. The study was published April 17 in the [...]ver notícia -
Agriculture needs fresh approach to tackle insect resistance to biopesticides, new analysis finds
Publicado em 13 março 2023For 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 control by switching to biopesticides derived from natural organisms. The evolution of resistance to biopesticides -- a crucial tool in the development of sustainable crop protection -- has huge implications for food [...]ver notícia -
A new ring system discovered in our Solar System
Publicado em 08 fevereiro 2023Scientists have discovered a new ring system around a dwarf planet on the edge of the Solar System. The ring system orbits much further out than is typical for other ring systems, calling into question current theories of how ring systems are formed. The ring system is around a dwarf planet, named Quaoar, which is approximately half the size of Pluto and orbits the Sun beyond Neptune. The discovery, published in Nature, was made by an international team of astronomers using HiPERCAM -- an [...]ver notícia -
Researchers Shed Light on How Exercise Preserves Physical Fitness During Aging
Publicado em 05 janeiro 2023Findings may represent promising strategies for promoting muscle function during aging Date: January 5, 2023 Source: Joslin Diabetes Center Summary: Researchers investigated the role of one cellular mechanism in improving physical fitness by exercise training and identified one anti-aging intervention that delayed the declines that occur with aging in the model organism. Together, the scientists' findings open the door to new strategies for promoting muscle function during [...]ver notícia -
Husker study: Brazil can grow more soybeans without deforesting Amazon
Publicado em 10 outubro 2022Brazil presents a key example. The country is home to the world’s largest area of rainforest — some 1.2 million square miles, an area more than 16 times the size of Nebraska. The Amazon contains large tracts of rainforests that, when converted to agriculture, release a huge amount of carbon dioxide into the atmosphere, exacerbating climate change. Increasing agricultural production is a national priority for Brazil, the world’s largest soybean exporter. Since the 1990s, [...]ver notícia -
Discovery and naming of Africa's oldest known dinosaur
Publicado em 31 agosto 2022An international team of paleontologists led by Virginia Tech has discovered and named a new, early dinosaur. The skeleton -- incredibly, mostly intact -- was first found by a graduate student in the Virginia Tech Department of Geosciences and other paleontologists over the course of two digs, in 2017 and 2019. The findings of this new sauropodomorph -- a long-necked dinosaur -- newly named Mbiresaurus raathi were been published today in the journal Nature. The skeleton is, [...]ver notícia -
Deciphering the biosynthetic gene cluster for potent freshwater toxin
Publicado em 20 maio 2022Scientists from Scripps Institution of Oceanography at the University of California San Diego, the University of São Paulo and UC Santa Cruz collaborated to discover and validate the enzymes responsible for the production ofone of the most toxic and fast-acting neurotoxins associated with freshwater harmful algal blooms in lakes and ponds. The team combined genetic and biochemical studies to show how freshwater cyanobacteria produce the potent neurotoxin called guanitoxin. This [...]ver notícia -
Amazon deforestation threatens newly discovered fish species in Brazil
Publicado em 16 maio 2022Smithsonian's National Museum of Natural History researcher Murilo Pastana and his colleagues have discovered and described two new species of Amazonian fish -- one with striking red-orange fins and the other so small it is technically considered a miniature fish species -- in a paper published today, May 16, in the Zoological Journal of the Linnean Society. Both species inhabit waters located at the bleeding edge of human encroachment into the Amazon rainforest roughly 25 miles [...]ver notícia
