A recent study has found that even mild cases of COVID-19 can have lasting negative effects on cardiovascular health. A groundbreaking study conducted a comparison of arterial stiffness between participants before and after contracting COVID-19. New research indicates that even mild instances of COVID-19 can lead to lasting harm to cardiovascular health. The study is … Read more
Photograph of Pinguicula ombrophila sp. nov. Credit: Álvaro J. Pérez A group of botanists from Ecuador, Germany, and the United States have identified two new distinct species of carnivorous plants notable for their striking appearance. These species are a part of the butterworts family (known scientifically as the genus Pinguicula), a group of insectivorous flowering … Read more
A study published in the journal Nature has proposed a new model for human evolution, asserting that modern Homo sapiens stemmed from multiple genetically diverse populations across Africa rather than a single ancestral population. This conclusion was reached after researchers analyzed genetic data from present-day African populations, including 44 newly sequenced genomes from the Nama … Read more
A new technique eliminates a source of bias in a popular simulation method, which could enable scientists to create new algorithms that are more accurate and boost the performance of applications and networks. Credit: Jose-Luis Olivares/MIT The system they developed eliminates a source of bias in simulations, leading to improved algorithms that can boost the … Read more
The Series 1 Lander was optimized for light weight, small size and reliability. Although the lander did not complete a soft landing, the cause has been identified and improvements are being incorporated into Mission 2 and Mission 3. Credit: ispace The HAKUTO-R Mission 1 lunar lander, launched by ispace in December 2022, failed to land … Read more
An umbrella review of 73 meta-analyses examining sugar consumption and health outcomes found significant harmful associations between dietary sugar intake and a variety of diseases, including obesity, heart disease, and certain cancers, although the evidence quality was often low. As a result, the researchers recommend reducing free sugar consumption to less than 25 g/day (around … Read more
Caltech-led studies propose new, stringent tests for Einstein’s general theory of relativity, seeking signs of quantum gravity in the ripples of spacetime generated by black hole collisions. One study presents an equation for black hole behavior within quantum gravity theories, building on previous work, while the second suggests a method for applying this equation to … Read more
In a groundbreaking study published in Nature Astronomy, a team of researchers led by Eileen Meyer at the University of Maryland, Baltimore County, has challenged the prevailing theories about x-ray emissions from black hole jets.

A new study supported by the National Institute of Mental Health has revealed an increase in suicide rates among young people during the COVID-19 pandemic. A recent study found that suicide rates among US youth aged 5-24 years increased during the COVID-19 pandemic, particularly among males, preteens, young adults, and specific racial and ethnic groups. … Read more
UC San Diego and Stanford scientists studied maize (corn) plant roots and their metabolites—molecules involved in the plant’s energy production—under different settings, including a control condition (left) and treated with aconitate (center) and succinate (right).
