Americans perceive small juries of content experts as the most legitimate moderators of potentially misleading content on social media, according to a survey, but perceive large, nationally representative or politically balanced juries with minimum knowledge qualifications as comparably legitimate. Social media content moderation policies tend to attract criticism, with some calling for more aggressive removal of harmful and misleading content and others decrying moderation as censorship and accusing expert moderators of being politically biased. Less clear is what the general public would like to see in terms of content ...

A Perspective proposes a pathway to improvements in sustainability of marine ecosystems and resources in China. Based on environmental accounting used in China’s terrestrial ecosystems, the approach would implement policy and governance to ensure accountability for sustainable use of marine systems. Laurence J. McCook and colleagues argue that the ecosystem goods and services provided to the nation by oceans and coastal ecosystems—including seagrass beds, salt marshes, coral reefs, and mangrove forests—are ...

A drug used to treat type 2 diabetes may also be effective in slowing the progression of prostate cancer. This is shown by an international study in which researchers at Umeå University, Sweden, have participated. The researchers have found that drugs that regulate a particular protein have a key role in reducing prostate cancer recurrence among diabetic patients. "This is a significant discovery. For the first time, we have clinical observations showing that prostate cancer patients with diabetes who received drugs targeting the protein remained relapse-free during the period we followed them," ...

New cases of dementia in the United States declined from 2015 to 2021, but the number of people living with the condition continued to rise due to population ageing, with nearly 2.9 million traditional Medicare beneficiaries (around 12%) living with a dementia diagnosis in 2021, finds a study published by The BMJ today. What’s more, a greater burden of dementia was seen in marginalized and low resource communities, highlighting the importance of policy approaches to promote equitable dementia care, say the ...

Efforts to limit the global temperature increase to 1.5°C under the Paris Climate Agreement may not go far enough to save the world’s ice sheets, according to a new study. Research led by Durham University, UK, suggests the target should instead be closer to 1°C to avoid significant losses from the polar ice sheets and prevent a further acceleration in sea level rise. The team reviewed a wealth of evidence to examine the effect that the 1.5°C target would have on the ice sheets in Greenland and Antarctica, which together store enough ice to raise global sea levels by almost 65 metres. The mass of ice lost from these ice ...

CAMBRIDGE, MA -- By combining information from many large datasets, MIT researchers have identified several new potential targets for treating or preventing Alzheimer’s disease. The study revealed genes and cellular pathways that haven’t been linked to Alzheimer’s before, including one involved in DNA repair. Identifying new drug targets is critical because many of the Alzheimer’s drugs that have been developed to this point haven’t been as successful as hoped. Working with researchers at Harvard Medical School, the team used data from humans and fruit flies to identify cellular pathways linked to neurodegeneration. ...

A combination of two drugs could improve outcomes and reduce the need for toxic chemotherapy for B-cell acute lymphoblastic leukaemia (B-ALL), the commonest cancer in childhood and one that can be particularly difficult to treat in older patients, according to Cambridge scientists. Although the research has so far only been conducted in cell lines and mice, the team is seeking funding to begin clinical trials in patients shortly. More than 500 people a year in the UK are diagnosed with B-ALL, many of whom are children, where it makes up 40% of all ...

CAMBRIDGE, MA -- Measuring the density of a cell can reveal a great deal about the cell’s state. As cells proliferate, differentiate, or undergo cell death, they may gain or lose water and other molecules, which is revealed by changes in density. Tracking these tiny changes in cells’ physical state is difficult to do at a large scale, especially with single-cell resolution, but a team of MIT researchers has now found a way to measure cell density quickly and accurately — measuring up to 30,000 cells in a single hour. The researchers also showed that density ...

Tokyo, Japan—The COVID-19 pandemic increased public awareness of the importance of mask use for personal protection. However, when the mesh size of mask fabrics is small enough to capture viruses, which are usually around one hundred nanometers in size, the fabric typically also restricts air flow, resulting in user discomfort. But now, researchers from Japan have found a way to avoid this. In a study published this month in Materials Advances, researchers from the Institute of Industrial Science, The University of Tokyo have overcome this bottleneck and developed a filter capable of capturing nanoparticles such ...

Leuven, 20 May 2025 - Researchers from the lab led by Prof. Joris De Wit (VIB-KU Leuven) have discovered an important clue to how connections between brain cells, known as synapses, mature. These new findings, published in Developmental Cell, demonstrated how two different proteins, GPR158 and PLCXD2, interact to form a specific component in developing synapses – the spine apparatus. Synapses – the communication points between neurons – are not only molecularly diverse but also contain specialized organelles, tiny internal cellular machines, that finetune their function. The spine apparatus is one such organelle, and it is essential for stabilizing mature ...

Philadelphia, May 20, 2025 – New research shows that in patients with psoriasis, even though their skin responds well to treatment with biologics, inflammation can linger, leading to broader health implications such as obesity and cardiovascular and fatty liver disease. The findings of the study in the Journal of Investigative Dermatology (JID), published by Elsevier, could lead to more targeted and effective treatments that address the systemic aspects of psoriasis, beyond just the skin. Systemic chronic inflammation has been implicated in several diseases that collectively represent the leading causes of ...

A new paper in Nicotine and Tobacco Research, published by Oxford University Press, finds that today’s pod-style electronic cigarette devices are more addictive than nicotine gum, indicating that such devices have a very high potential for abuse. Since entering the market in 2003, electronic cigarettes have become very popular in the United States, particularly among youth and young adults. A significant proportion of people who use electronic cigarettes devices never used other tobacco products regularly. Over 30% of adult users of vaping devices report no history of regular cigarette smoking, a rate ...
