Using an approach based on computer vision technology, researchers can work back from COVID-19 mortality data to see how infection rates changed on the day a lockdown or similar measure was introduced. The approach could be generally useful in future epidemics and pandemics. The work is published July 14 in Science Advances.  Coauthors Leonor Saiz, professor of biomedical engineering at the University of California, Davis, and Jose Vilar, University of the Basque Country, Spain, wanted to see the effects of non-pharmaceutical interventions such as social distancing, lockdowns and masking in the first year of the pandemic. They looked at daily death reports from European ...

Block ciphers, a branch of modern cryptography, are playing a more prominent role in protecting information security as 5G technology develops. Although encryption algorithms of the traditional Feistel structure have great advantages in terms of consistent encryption and decryption, they have poor diffusion effects. Besides, they cannot adapt to the high throughput communication environment and resource-constrained devices. The S-box is the crucial nonlinear component in the block cipher and significantly determines the security of an algorithm. Unfortunately, the vast proportion of S-boxes exist in a static manner, which ...

CHICAGO --- Aerobic glycolysis, the process by which cells transform glucose into lactate, is key for eye development in mammals, according to a new Northwestern Medicine study published in Nature Communications. While it has been well known that retinal cells use lactate during cell differentiation, the exact role that this process plays in early eye development was not previously understood. The findings further the field’s understanding of the metabolic pathways underlying organ development, according to ...

In 2020, Japan performed the first successful test extracting cobalt crusts from the top of deep-sea mountains to mine cobalt—a mineral used in electric vehicle batteries. Not only do directly mined areas become less habitable for ocean animals, but mining also creates a plume of sediment that can spread through the surrounding water. An investigation on the environmental impact of this first test, published July 14th in the journal Current Biology, reports a decrease in ocean animals both in and around the mining zone. The International ...

Tucked into the hillsides of Italy, Portugal, and Spain, some of the world’s most famous—and most difficult to maintain—vineyards are heralded for their unique flavor profiles and centuries of tradition. But as extreme weather and changing socioeconomic conditions make this so-called “heroic viticulture” even more challenging, scientists worry these grapes and their cultural histories are at risk. In a Backstory publishing on July 14 in the journal iScience, researchers argue that farmers and scientists must work together to protect ...

In the animal world, you don't need to learn a numeral system – such as the ten-digit Indo-Arabic system we commonly use – to be able to count. Animals constantly use numerical information from their environment to make decisions. Estimating the number of conspecifics in a competing group before engaging in conflict, the amount of food available in a difficult-to-reach location, or the number of potential sexual partners in a new territory is essential for survival and reproduction. This skill can reach an astonishing level of refinement; for example, certain species of ants orient themselves ...

About The Study: In this secondary analysis of an 18-month randomized trial that included 135 older adults, meditation and non-native language training did not confer salutary cognitive effects. Although further analyses are needed to explore the effects of these interventions on other relevant outcomes related to aging and well-being, these findings did not support the use of these interventions for enhancing cognition in cognitively healthy older adults.  Authors: Natalie L. Marchant, Ph.D., of University College London, is the corresponding author.  To access the embargoed study: Visit our For The Media website at this link https://media.jamanetwork.com/  (doi:10.1001/jamanetworkopen.2023.17848) Editor’s ...

About The Study: This nationwide cross-sectional study demonstrated that residing in a highly segregated neighborhood was associated with a statistically significantly lower life expectancy by four years, which was partially mediated by neighborhood-level socioeconomic factors.

About The Study: In this study of 10,000 older individuals in Australia, more frequent participation in adult literacy activities (taking education classes, using a computer, and writing letters or journals) and in active mental activities (playing games, cards, or chess and doing crosswords or puzzles) was associated with reduced dementia risk over 10 years. However, social outings and interactions were not associated with dementia risk.  Authors: Joanne Ryan, Ph.D., of Monash University in Melbourne, Australia, is ...

BENTLEY UNIVERSITY The U.S. National Institutes of Health (NIH) contributed $8.1 billion in project funding for phased clinical trials involving drugs approved by the FDA from 2010-2019, according to a new study from Bentley University’s Center for Integration of Science and Industry. The study, published in JAMA Health Forum, shows that NIH funding for clinical trials represents <3.5% of total NIH spending for basic or applied research related to these products and was significantly less than reported industry spending on clinical development. ...

The electric grids of the future will need to handle much bigger loads due to electrification of transportation and other sectors. This could mean expensive infrastructure upgrades to ensure their reliable operation, but a new study from Stanford University says most of those upgrades may be unnecessary. Better grid reliability could be achieved instead by installing software in homes and businesses that coordinates various consumer demands and resources. Such coordination not only improves reliability of the electric grid, but also ...

Antibodies are crucial, not only for treating tumors and infections. Sometimes, however, the immune reaction they trigger can be too strong and end up causing more damage, for example in the case of people infected with Covid-19. Problems such as these can often be avoided by finetuning antibodies, as Prof. Dr. Falk Nimmerjahn from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and two of his colleagues in the Netherlands and in the UK have now reported in the journal Nature Immunology. In his laboratories, the FAU researcher is carrying out research into immunoglobulin ...
