Nanoparticles can improve stroke recovery by enhancing brain stimulation, study shows
In a recent study, researchers from Xi'an Jiaotong-Liverpool University and other universities in China have reported that brain stimulation combined with a nose spray containing nanoparticles can improve recovery after ischemic stroke in an animal model.
Social resistance of Bronze Age communities in response to emerging state societies in the Iberian Peninsula
A UAB study using a Big Data approach to analyze settlement dynamics reveals that communities of the central-eastern Iberian Peninsula existing 4,000 years ago deployed "escape economies," using enrockment and segmentation tactics to protect themselves from the exploitation and conflicts arising from the expansion of the El Argar society, one of the first state societies in Europe.
AI better than humans at detecting blue whale calls
Whale scientists could soon do themselves out of a job—or at least a tiring and repetitive one—by applying artificial intelligence (AI) to their research.
Research conducted throughout the Russian invasion is helping save Ukraine's historic artworks
Researchers from the Natural History in London have collaborated with researchers from the National Academy of Sciences of Ukraine to establish the cause of damage to the world-famous medieval murals in Kyiv's Saint Sophia Cathedral—one of Ukraine's most important cultural sites.
Gather ideas from strangers, but work through them with people close to you
The creative process, in any knowledge-based activity, is increasingly a collective process, and those who take charge of its development must know how to activate the most appropriate personal ties at each stage. In an article in Academy of Management Journal, Pier Vittorio Mannucci (Bocconi Department of Management and Technology) and Jill E. Perry-Smith (Emory University), conducted a series of...
No environmental sustainability means no positive peace, and vice versa
Peace and environmental sustainability—two lofty but vital goals for all countries—are known to be intrinsically related, according to Dahlia Simangan, associate professor at the Graduate School of Humanities and Social Sciences at Hiroshima University. However, researchers still tend to investigate them separately, and, when they are viewed together, it is often with broad strokes, with...
As glaciers melt at an alarming pace, a geologist reflects on the legacy of ice ages and what the future may hold
With continued news of glaciers in Greenland, Antarctica, Alaska and the Alps, as well as other parts of the world, melting far faster than predicted, Tufts Now turned to an expert on ice sheets and the last ice age to better understand the big picture.
Success of experimental Alzheimer’s drug hailed as ‘historic moment’
Study shows cognition in early-stage patients on lecanemab declines by 27% less than those on placeboAn experimental drug has slowed the rate of decline in memory and thinking in people with early Alzheimer’s disease in what is being described as a “historic moment” for dementia treatment.The cognition of Alzheimer’s patients given the drug, developed by Eisai and Biogen, declined by 27%...
‘Honorary authors’ of scientific papers abound—but they probably shouldn’t
It’s a practice that makes some scientists cringe: The lead author of a paper pays homage to a department chair, or a colleague who helped secure a grant, by listing them among the manuscript’s authors—even though the person made no intellectual contribution to the paper. Such “honorary authorship” is discouraged by many journals, publishing industry groups, and universities,...
Ultra-diffuse galaxy F8D1 has a giant tidal tail, observations find
Using the Subaru telescope and the Canada-France-Hawaii Telescope (CFHT), an international team of astronomers has observed an ultra-diffuse galaxy known as F8D1. The observational campaign has revealed an enormous tidal stream emanating from this galaxy. The finding was presented September 21 on the arXiv pre-print server.
Single cell research spotlights the role of DNA methylation in cell fate decisions
Research applying single-cell analysis techniques and comparisons to a cell atlas resource allowed researchers at the Babraham Institute to connect observed development defects caused by disrupted DNA methylation processes with an understanding of the cell types affected. This work, published in Genome Biology, builds on previous work undertaken with collaborators to establish a detailed cell...
Radical action is needed for the climate. This means transforming the way we do science
Record-breaking heat waves, droughts and floods make regular headlines around the globe, and scientists say the risk, frequency and intensity of these weather extremes are tied to the ever-increasing levels of planet-heating gases we pump into the atmosphere. Humanity's incremental response to the climate crisis has yet to show signs of getting the existential threat under control. Radical,...
Better understanding of cellular metabolism with the help of AI
Metabolism is essential to all living organisms, and modeling the chemical reactions that sustain life is no easy task. Now, EPFL scientists have released REKINDLE, a deep-learning process that is paving the way for more efficient and accurate modeling of metabolic processes.
Relationship between song order and rhythmical timing in songbirds
An international collaboration between musicians and birdsong scientists has found that in the Australian pied butcherbird songs surveyed, the order of song elements is strongly related to rhythmical timing.
Researchers use multiple lasers to create reproducible coherent light structures at wavelength level
Scientists from Japan have employed theoretical calculations to model the optical radiation force distribution induced by an arbitral light pattern including an interference pattern. Based on the simulations, they were able to fabricate nano-sized structures in array that may lead to new optical devices, such as chirality sensors.
The Download: China’s non-coup, and building better batteries
This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. How the false rumor of a Chinese coup went viral If you’re on Twitter and follow news about China, you likely have heard a pretty wild rumor recently: that President Xi Jinping was…

Scientists have discovered how a chemical in the cells of marine organisms enables them to survive the high pressures found in the deep oceans.
A new window into plants of the past
- ScienceDaily
- 22/9/28 13:59
Herbaria collections have long served as a vital record of what plant species exist on Earth and where they grow. But hidden within the desiccated leaves, stems, flowers and roots is far more information on how the plants interacted with their environment while they were alive. Until now the only way to learn about these traits from herbarium collections has required destroying bits of the...
Omega-3 fatty acids, and in particular DHA, are associated with increased attention scores in adolescents
- ScienceDaily
- 22/9/28 13:59
Docosahexaenoic acid (DHA) is associated with a greater capacity for selective and sustained attention in adolescents, while alpha-linolenic acid (ALA) is associated with lower impulsivity, according to a new study. The results confirm the importance of having a diet that provides sufficient amounts of these polyunsaturated fatty acids for a healthy brain development.
Hurricane Ian strengthens to Category 4 as it barrels toward Florida
Hurricane Ian strengthened to a Category 4 storm as it headed towards the US state of Florida on Wednesday, with forecasters warning of life-threatening storm surges and "devastating" winds after it reportedly killed two and left millions without power in Cuba.
