The Event Horizon Telescope (EHT) Collaboration has conducted test observations, using the Atacama Large Millimeter/submillimeter Array (ALMA) and other facilities, that achieved the highest resolution ever obtained from the surface of Earth [1]. They managed this feat by detecting light from distant galaxies at a frequency of around 345 GHz, equivalent to a wavelength of 0.87 mm. The Collaboration estimates that in future they will be able to make black hole images that are 50% more detailed than was possible before, bringing the region immediately outside the boundary of nearby supermassive black holes into sharper focus. They will also ...

COLUMBUS, Ohio – A proposed artificial intelligence tool to support clinician decision-making about hospital patients at risk for sepsis has an unusual feature: accounting for its lack of certainty and suggesting what demographic data, vital signs and lab test results it needs to improve its predictive performance. The system, called SepsisLab, was developed based on feedback from doctors and nurses who treat patients in the emergency departments and ICUs where sepsis, the body’s overwhelming response to an infection, is most ...

A study finds an increased risk of developing a productive SARS-CoV-2 infection in obese people. Obesity is known to predict worse outcomes and higher mortality for those with COVID-19. Masanori Aikawa and colleagues sought to determine if obesity also affected the likelihood of getting ill in the first place. To investigate, the authors analyzed electronic medical records for 687,813 patients from the Mass General Brigham healthcare system, including 72,613 individuals with suspected SARS-CoV-2 exposure, 18,447 of whom tested positive. The authors limited their data to a timeframe before vaccination became widespread in Massachusetts, to avoid the possible confounding ...

A close reading of Darwin’s work suggests a deep interest in cyclical events. Rhythmic phenomena in nature—today the subjects of the field of chronobiology—have been studied since at least the 18th century. In a perspective, Tiago Gomes de Andrade and Andrew D. Beale examined the writings and work of Charles Darwin to explore and share the eminent naturalist’s deep fascination with biological rhythms. Darwin’s work on the “sleep movements” in plants, published in 1880 with his son Francis is well known. This work examined the daily cycle of opening and closing of leaves. But as far ...

Amidst the ongoing energy crisis and under the threat of climate change, exploiting renewable energy sources has quickly become a global necessity. Though our options are varied, solar energy seems to be our best bet—experts estimate that it may become our main energy source well before the turn of the century. Despite its clear advantages, solar energy generation has some limitations. Much like the wind, solar irradiance in a given region can vary quickly depending on weather conditions, causing fluctuations in power ...

Sophia Antipolis, France – 27 August 2024: Cardiovascular disease (CVD) remains the most common cause of death across Europe but while CVD mortality rates are generally decreasing, the decline is much less in middle-income than in high-income countries, according to new data from the European Society of Cardiology (ESC) Atlas of Cardiology, published in the European Heart Journal.1  The fourth edition of ESC Atlas statistics again demonstrate that CVD is the most common cause of death in the 55 ESC member countries studied. There are over 3 million deaths due to CVD per year – the equivalent of 8,500 deaths per day – which represents 37.4% of all deaths annually. ...

27 August 2024, Singapore – A KK Women’s and Children’s Hospital (KKH) study[1] on breastfeeding practices revealed that among the women who exclusively breastfed, those with high body mass index[2] (BMI) before pregnancy lost more weight than women with a healthy BMI pre-pregnancy. Women with high BMI who exclusively breastfed, in addition to losing their pregnancy weight, lost an extra 200 grammes on average, 12 months after childbirth. Women with normal BMI who exclusively breastfed lost weight ...

The authors investigate the physiological functions of Terc-53 by creating transgenic mice that overexpress this noncoding RNA. They observe that Terc-53 overexpression affects normal aging in mammals, contributing to cognitive decline and shortened lifespan. Mechanistically, they find that Terc-53 binds to and promotes the degradation of Hmmr, leading to enhanced inflammation in tissues and accelerated aging. They also note that Hmmr levels decrease with age in certain brain regions, similar to Terc-53's pattern, and that restoring Hmmr levels can improve cognitive abilities ...

A team of researchers led by Rutgers University-New Brunswick scientists has analyzed crop yields of more than 1,500 fields on six continents, and found that production worldwide of important, nutritionally dense foods such as fruits, vegetables, nuts and legumes is being limited by a lack of pollinators. The results, detailed in Nature Ecology & Evolution, showed that across diverse crops and locations, one-third to two-thirds of farms contain fields that aren’t producing at the levels they should be due to a lack of pollinators. The phenomenon of a low crop yield because of insufficient visits by insects is known as pollinator limitation. The ...
