Invasive weed may help treat some human diseases, researchers find

Native to the southeastern United States, a weedy grass has spread northward to Canada and also made its way to Australia and Japan. Andropogon virginicus grows densely packed and up to seven feet tall, disrupting growth patterns of other plants and competing for resources. When burned, it grows back stronger. There is no way to effectively remove the weed once it has invaded. But there might be a way to use it to human advantage.

Tiny diamonds prove an excellent material for accelerator components

When it comes to producing high-quality electron beams like those found in state-of-the-art scientific equipment like free-electron lasers, ultrafast electron diffraction and imaging and wakefield accelerators, scientists have looked to photocathode technology as a way to convert light to electrons. These tools give researchers a way to more deeply penetrate into materials and atomic structure and behavior under real-world conditions.

'Magic sand' might help us understand the physics of granular matter

Sand is a fascinating material. It can flow and be poured like a liquid, but retains many of the properties of solids, clogging pipes or forming sand dunes. The behavior of collections of small particles like sand is known as granular physics, and is an immensely important field for the handling and transport of the wide range of granular materials out there like grains, rice, powders and the vast amounts of sand used in the construction industry.

Most distant quasar with powerful radio jets discovered

With the help of the European Southern Observatory's Very Large Telescope (ESO's VLT), astronomers have discovered and studied in detail the most distant source of radio emission known to date. The source is a "radio-loud" quasar—a bright object with powerful jets emitting at radio wavelengths—that is so far away its light has taken 13 billion years to reach us. The discovery could provide important clues to help astronomers understand the early Universe.

Stroke affecting the eye requires immediate treatment, can signal future vascular events

While most people think of strokes affecting the brain, they can also affect the eye. Central retinal artery occlusion (CRAO) is a rare form of acute ischemic stroke that occurs when blood flow is blocked to the main artery of the eye. It typically causes painless, immediate vision loss in the impacted eye, with fewer than 20% of people regaining functional vision in that eye.

Cardiac arrest from opioid overdose has unique features affecting prevention and treatment

Out-of-hospital cardiac arrests triggered by opioid overdose are a significant cause of death among adults 25 to 64, according to a scientific statement from the American Heart Association, the nation's largest voluntary health organization focused on heart and brain health for all. The statement published today in the Association's flagship journal Circulation.

Diphtheria risks becoming major global threat again as it evolves antimicrobial resistance

Diphtheria—a relatively easily-preventable infection—is evolving to become resistant to a number of classes of antibiotics and in future could lead to vaccine escape, warn an international team of researchers from the UK and India.

England's children go back to school after virus lockdown

Children return to school in England on Monday for the first time since January, as the government begins to ease tough restrictions thanks to a mass vaccination drive against the coronavirus.

Globalization of cancer clinical trials linked to lower enrollment of Black patients

For the drug approval process in the United States, investigators have been expanding clinical trials to sites outside the country. However, a new study indicates that this trend may be widening racial disparities in patient enrollment in cancer clinical trials. The study is published by Wiley early online in Cancer, a peer-reviewed journal of the American Cancer Society.

New Lancet series shows mixed progress on maternal and child undernutrition in last decade

The Lancet today published the latest Series on Maternal and Child Undernutrition Progress, including three new papers that build upon findings from the previous 2008 and 2013 Series, which established an evidence-based global agenda for tackling undernutrition over the past decade. The papers conclude that despite modest progress in some areas, maternal and child undernutrition remains a major global health concern, particularly as recent gains may be offset by the COVID-19 pandemic. The Series reiterates that previously highlighted interventions continue to be effective at reducing stunting, micronutrient deficiencies, and child deaths and emphasizes the importance of delivering these nutrition interventions within the first 1,000 days of life. However, despite this evidence, program delivery has lagged behind the science and further financing is needed to scale up proven interventions.
