(Boston)—Nearly all cervical cancers are caused by the human papillomavirus (HPV). New evidence has led to dramatic changes in cervical cancer screening recommendations over the past 20 years. In 2020, the American Cancer Society (ACS) released updated guidelines for cervical cancer screening. The main changes to current practices were to initiate screening at age 25 instead of age 21 and to screen using primary HPV testing rather than cytology (PAP test) alone or in combination with HPV testing. Since adoption of guidelines often occurs slowly, understanding clinician attitudes is important ...

The Arctic could see summer days with practically no sea ice as early as the next couple of years, according to a new study out of the University of Colorado Boulder.    The findings, published March 5 in the journal Nature Reviews Earth ­­& Environment, suggest that the first ice-free day in the Arctic could occur over 10 years earlier than previous projections, which focused on when the region would be ice-free for a month or more. The trend remains consistent under all future emission scenarios.   By ...

About The Study: In this multiyear cross-sectional study of a representative sample of young children in the U.S., the increased prevalence of high screen time in 2020 returned to pre-pandemic levels in 2021; however, it remained elevated in children living in poverty. Two hours or more of daily screen time was associated with lower psychological well-being among preschool-aged children. Authors: Soyang Kwon, Ph.D., of Northwestern University in Chicago, is the corresponding author. To access the ...

Adults who sleep only three to five hours a day are at higher risk of developing type 2 diabetes. This is demonstrated in a new study from Uppsala University, published in JAMA Network Open. It also shows that chronic sleep deprivation cannot be compensated by healthy eating alone.      “I generally recommend prioritising sleep, although I understand it’s not always possible, especially as a parent of four teenagers,” says Christian Benedict, Associate Professor and sleep researcher at the Department of Pharmaceutical Biosciences at Uppsala University and leading researcher behind the study. He and a team of researchers have examined the link between type 2 ...

Liver cancer, unfortunately, is the sixth most common cancer and the third most frequent cause of cancer-related death globally. However, its distribution and causes vary greatly across different regions. While areas like Eastern Asia and sub-Saharan Africa see the most cases, the reasons behind them differ significantly. In high-income countries, liver cancer has been on the decline thanks to widespread newborn hepatitis B vaccination and antiviral drugs. Meanwhile, low-income countries witness a worrying rise, ...

Sprinting “like a jet plane taking off” will help produce Premier League star strikers of tomorrow, new research has revealed.   A University of Essex study of Tottenham Hotspur’s academy has shown that just a few words can instantly boost sprinting speed by 3 per cent over 20 metres.    It would normally take weeks of targeted training to achieve such a large increase.  These short bursts of acceleration are largely seen in goal-scoring situations and could be the difference in beating a defender and finding the net.  Dr Jason Moran, from the School of Sport, Rehabilitation and Exercise Sciences, discovered simple analogies increased ...

OAK BROOK, Ill. – Coronary artery calcium scoring with CT can identify symptomatic patients with a very low risk of heart attacks or strokes, according to a new study published today in Radiology, a journal of the Radiological Society of North America (RSNA). Researchers said the findings may one day help some patients with stable chest pain avoid invasive coronary angiography. Coronary artery calcium scoring with CT was developed to noninvasively measure the amount of calcium in the arteries of the heart. Higher scores are linked with atherosclerosis, a buildup of plaque in the arteries. A score of 1 to 399, for instance, suggests a moderate amount of plaque, while 400 ...

Although several studies have linked smoking during pregnancy with neurodevelopmental disorders, the results of behavioral experiments in mice prenatally exposed to nicotine have been inconsistent. In a recent study, scientists from Japan developed a deep learning-based framework to automatically observe and classify mice behavior in such experiments, producing more accurate and unbiased results. They show that prenatal exposure to nicotine could increase the risk of autism spectrum- and attention deficit/hyperactivity disorders in newborns. The fact that smoking is a risk factor for several diseases, including cancer, stroke, and diabetes, has been known for approximately ...

The stunning images, captured using the European Southern Observatory's Very Large Telescope (ESO’s VLT) in Chile, represent one of the largest ever surveys of planet-forming discs. The research brings together observations of more than 80 young stars that might have planets forming around them, providing astronomers with a wealth of data and unique insights into how planets arise in different regions of our galaxy. “This is really a shift in our field of study,” says Christian Ginski, a lecturer at the University of Galway, Ireland, ...

A theoretical experiment characterized the network architecture of a species-rich ecosystem over 8 months. Predator–prey interaction networks play a key role in structuring ecosystems, but ecological research has often treated such networks as static, despite the broadly accepted understanding of ecosystems as dynamic. Hirokazu Toju and colleagues followed the complex food webs between 50 predatory spider species and 974 prey species, including midges, springtails, mosquitoes, and aphids, for eight months. The studied ecosystem is a warm-temperate grassland ...

In the Japanese art of Kintsugi, an artist takes the broken shards of a bowl and fuses them back together with gold to make a final product more beautiful than the original.  That idea is inspiring a new approach to managing plasma, the super-hot state of matter, for use as a power source. Scientists are using the imperfections in magnetic fields that confine a reaction to improve and enhance the plasma in an approach outlined in a new paper in the journal Nature Communications. “This approach allows you to maintain ...

Researchers built a model that can predict with 73.5% accuracy when a person will experience aesthetic chills: shivers, goosebumps, or a feeling of cold down the neck or spine elicited by aesthetic stimuli, such as beautiful music or an inspirational speech. Felix Schoeller and colleagues surveyed 2,937 people from Southern California, through an online platform, gathering data on their personalities, demographic backgrounds, and emotional state. The authors then exposed survey respondents to 40 emotion-evoking audiovisual clips sourced from social media, selected because commenters had reported experiencing aesthetic chills while watching and listening. ...

PULLMAN, Wash. – Bacteria can be tricked into sending death signals to stop the growth of their slimy, protective homes that lead to deadly infections, a new study demonstrates. The discovery by Washington State University researchers could someday be harnessed as an alternative to antibiotics for treating difficult infections. Reporting in the journal, Biofilm, the researchers used the messengers, which they named death extracellular vesicles (D-EVs), to reduce growth of the bacterial communities by up to 99.99% in laboratory experiments. “Adding the death extracellular vesicles to ...

Text-to-image generative AI systems like Midjourney, Stable Diffusion, and DALL-E can produce images based on text prompts that, had they been produced by humans, would plausibly be judged as “creative.” Some artists have argued that these programs are a threat to human creativity. If AI comes to be relied on to produce most new visual works, drawing on what has been done before, creative progress could stagnate. Eric Zhou and Dokyun “DK” Lee investigated the impact of text-to-image AI tools on human creativity, seeking to understand ...

Since its introduction, cryptocurrency governance has been one of the most controversial global financial topics. While some countries have established elaborate regulations for cryptocurrencies, many countries are still reluctant to oversee the markets, and some have outright banned them. Most studies suggest that public agencies naturally want to regulate markets and bring them into their purview. However, the significant differences in cryptocurrency regulation over the world call this view into question. Moreover, these differences cannot be explained by the development ...
