Targeted alpha therapy: One compound holds promise for unified cancer care‎

ORNL is a leader both in developing advanced radiotherapies and in providing the radioisotopes needed for those therapies. According to Karen Sikes, director of the National Isotope Development Center, the lab is home to more than 300 isotopes that are available to researchers and others. Besides actinium-225, medical radioisotopes on the list include lead-212, an in vivo alpha emitter generator going through clinical trials for the treatment of liver, prostate, skin and other cancers, and actinium-227, which decays to the alpha emitter radium-223, found in the approved drug Xofigo used to treat prostate cancers that have spread to bone.

Dallas-Fort Worth has untapped innovation potential, study says‎

Dallas-Fort Worth has all the right ingredients to be a national powerhouse for innovation—from a robust economy, world-class research universities to a diverse, dynamic workforce—yet an SMU-led study found the region isn't fully realizing that potential. The study, published in IEEE Transactions on Engineering Management, found that DFW's innovation productivity is lower than expected based on its assets and strengths. The metroplex was one of 65 U.S. regions measured in patent activity after adjusting for income, education, unemployment, and startup activity.

New material can collect clean and safe drinking water from the air‎

Climate change, population growth, conflict and humanitarian crises are putting increasing pressure on the world's water resources. That is why Norwegian researchers are looking into whether atmospheric water generators can become part of the solution. This type of water generator extracts moisture from the air using moisture-absorbing materials and converts it into drinking water. But they need to become more efficient.

Research reveals hidden ocean heat waves threatening South China Sea ecosystems‎

The South China Sea (SCS), a vital marine region supporting rich biodiversity, productive fisheries, and extensive coral reefs, faces growing threats from marine heat waves (MHWs). While surface MHWs have drawn attention, subsurface events—intense warming below the ocean surface—during boreal winter have been less studied, yet they can disrupt deeper-dwelling species and ecosystem stability in this semi-enclosed sea.

Researchers explore new ways to neutralize germs using light-activated nanomaterials‎

At Empa, an interdisciplinary research institute for materials science and technology within the ETH Domain, researchers are working on ways to kill harmful bacteria and viruses. In the Nanomaterials in Health Lab, headed by Peter Wick, scientists are studying how highly specialized materials interact with the human body, the health risks they pose and their potential to tackle a variety of medical issues.

How Edvard Munch's painting 'The Scream' might look in 300 years' time‎

If your great-grandparents ever saw "The Scream," they probably experienced a slightly different painting than the one we see today. Edvard Munch used materials that make his paintings vulnerable to the ravages of time. A new digital tool now shows how much "The Scream" may change over the next 300 years.

Natural textile fibers may persist for more than a century in lake sediments‎

Natural fibers promoted as sustainable alternatives to plastic, including cotton and wool, have been found preserved in a U.K. lake for more than a century—challenging assumptions that they quickly biodegrade in the environment. For the study, researchers from Keele University and Loughborough University recovered textile fibers from a 150-year sediment record from Rudyard Lake in Staffordshire. Lying less than three miles from the historic mill town of Leek, once a center of the country's textile industry, Rudyard Lake sits downstream of a significant site of industrial-era manufacturing activity.

Light-activated material offers new approach to carbon dioxide conversion‎

Scientists have developed a new material that can use sunlight and water to convert carbon dioxide (CO₂) into carbon monoxide (CO)—a key building block for making fuels, plastics, pharmaceuticals and other everyday chemicals. The finding could support the development of future technologies that recycle greenhouse gases to make fuels and useful chemicals more sustainably, using nothing more than light and water.

Using cow dung for sustainable carbon dioxide capture‎

Climate change is one of the most pressing global challenges in the present times. Increasing carbon dioxide (CO2) concentrations in the atmosphere are a major factor contributing to this phenomenon. Activities such as the burning of fossil fuels for daily use, like electricity and transportation, and industrial applications, release significant amounts of CO2, trapping the heat at excessive levels and contributing to global warming.

Decline in Japanese chum salmon linked to climate change‎

Today, most of the salmon consumed in Japan is imported from countries like Chile and Norway, according to the Ministry of Agriculture, Forestry and Fisheries. But just two decades ago, Japanese chum salmon made up a much larger share of domestic salmon consumption. Their numbers have declined sharply in recent years, and new research from Hokkaido University suggests that this decline may be linked to the loss of their natural habitats along their migratory routes.
