New report: How the pandemic compounds education pipeline challenges
The Western Interstate Commission for Higher Education (WICHE) has released new analysis based on updated data that suggests potentially greater long-term public school enrollment challenges, as well as recommendations for educational leaders and policymakers as they continue to grapple with the impacts of COVID-19 on the K-12 pipeline. This new analysis focuses on public school enrollment changes...
Closed loop for circular economy: New polymer recycling strategy ensures both high stability and complete recyclability
The ever-increasing generation of plastic solid waste has resulted in global plastic pollution both on land and in the oceans. Projections show that plastic waste will double in the next 20 years, causing further environmental problems. Large amounts of plastic waste are, at present, incinerated or deposited in landfills. This not only degrades the environment but also depletes valuable resources.
New study uncovers unprecedented declines in iconic kelp forests along Monterey Peninsula
A new study published in PLOS ONE provides novel documentation of kelp forest decline along the west coast of the U.S. and Mexico in response to the 2014–2016 record-breaking marine heatwave, along with evidence of regional recovery. Using Kelpwatch.org, an open-source web tool used to visualize and analyze nearly 40 years of kelp canopy dynamics data derived from satellite imagery, the study...
Team develops 2D ultrasound-responsive antibacterial nano-sheets to effectively address bone tissue infection
A research team led by Professor Kelvin Yeung Wai-kwok from the Department of Orthopaedics and Traumatology, School of Clinical Medicine, LKS Faculty of Medicine, the University of Hong Kong (HKUMed) has invented a non-invasive and non-antibiotics technology to effectively reduce methicillin-resistant Staphylococcus aureus (MRSA) infection in bony tissue.
To uncover new fluid flow laws, researchers turn to drinking straws
A team of researchers has uncovered new laws governing the flow of fluids through experiments on a technology thousands of years old: a drinking straw. This knowledge could be useful for improving fluid handling in medical and engineering applications.
Using targeted computer modeling to accelerate antiviral drug development
Effective drugs against viral diseases like COVID-19 are urgently needed now and in the future. The emergence of viral mutants and yet unknown viruses could push vaccines to their limits.
Hard-right social media activities lead to civil unrest, says paper
Does activity on hard-right social media lead to civil unrest? With the emergence and persistent popularity of hard-right social media platforms such as Gab, Parler, and Truth Social, it is important to understand the impact they are having on society and politics. Previous research on the relationship between social media use and subsequent offline behavior has been ambiguous. While some studies...
The 'Stonehenge calendar' shown to be a modern construct
Stonehenge is an astonishingly complex monument, which attracts attention mostly for its spectacular megalithic circle and "horseshoe," built around 2600 BC.
Dairy sector boasts 100 years of successful herd data collection
The U.S. dairy industry operates a comprehensive data collection program that records herd production information from farmers nationwide. The program provides crucial input for cattle breeding and genetics, and its cooperative structure ensures benefits for producers and scientists alike. A new study from the University of Illinois explores the program's century-old history, highlighting its...
Paper written using ChatGPT demonstrates opportunities and challenges of AI in academia
ChatGPT has the potential to create increasing and exciting opportunities—but also poses significant challenges—for the academic community, according to an innovative study written in large part using the software.
Study: SARS-CoV-2 can alter genome structure of our cells
People infected with SARS-CoV-2, the virus that causes COVID-19, may experience genome structure changes that not only may explain our immunological symptoms after infection, but also potentially link to long COVID, according to a new study by researchers at UTHealth Houston.
Hubble monitors changing weather and seasons of Jupiter and Uranus
Ever since its launch in 1990, NASA's Hubble Space Telescope has been an interplanetary weather observer, keeping an eye on the largely gaseous outer planets and their ever-changing atmospheres. NASA spacecraft missions to the outer planets have given us a close-up look at these atmospheres, but Hubble's sharpness and sensitivity keeps an unblinking eye on a kaleidoscope of complex activities over...
Improved ATLAS result weighs in on the W boson
The W boson, a fundamental particle that carries the charged weak force, is the subject of a new precision measurement of its mass by the ATLAS experiment at CERN.
Eco-friendly foam can insulate buildings without warming the globe
Rigid foam boards used to insulate buildings can prevent energy loss, making homes more efficient at keeping warm or cool. The advantages in energy efficiency, however, are undercut by environmental concerns over polystyrene products. Blowing agents used in foam production, such as hydrocarbons and hydrofluoroolefins, end up in the atmosphere and contribute to global warming.
Study: Mapping people's knowledge of bees may aid in pollinator conservation
U.S. college students' knowledge of bees focuses primarily on honey bees and pollination services, according to Penn State researchers, who said findings from their recent study could help in designing campaigns to generate support for protecting threatened pollinators.
Climate change threatens global fisheries
The diet quality of fish across large parts of the world's oceans could decline by up to 10% as climate change impacts an integral part of marine food chains, a major study has found.
New reports outline bold goals for U.S. bioeconomy
On March 22, the White House Office of Science and Technology Policy released a series of five reports authored by federal agencies, including the U.S. National Science Foundation, outlining bold research and development goals for the U.S. bioeconomy.
Sweden's sky lights up with northern lights research
Scientists in Sweden put on a light show in the night sky on Thursday, releasing material from a sounding rocket to research the spectacular northern lights phenomena.
How salt can taste sweet: The myriad mechanisms of taste perception
Humans perceive five basic taste sensations: sweet, umami, bitter, salty, and sour. Specific foods trigger taste recognition of these sensations through the activation of different receptors in our taste buds. In the case of table salt, the concentration is also an important factor in determining taste.
Large asteroid coming close, but zero chance of hitting us
An asteroid big enough to wipe out a city will zip harmlessly between Earth and the moon's orbit this weekend, missing both celestial bodies.
Feel your pain? Even fish can show they care
Our capacity to care about others may have very, very ancient origins, a new study suggests.
Climate science pioneer Claude Lorius, dies at 91
Leading glaciologist Claude Lorius, whose Antarctica discoveries in the 1980s helped prove humanity's role in global warming, has died at 91.
Study: Lithosphere architecture controls the formation of orogenic gold deposits
Professor Zhang Haijiang from the School of Earth and Space Sciences, University of Science and Technology of China (USTC), in collaboration with academician Hou Zengqian from the Institute of Geology, Chinese Academy of Geological Sciences, and Professor Wang Qingfei from the China University of Geosciences (Beijing), have discovered that the lithosphere architecture characterized by crust-mantle...
The journey of a carbon atom: From space, NASA's PACE mission detects carbon in the sky, land and sea
Whether in plants or animals, greenhouse gases or smoke, carbon atoms exist in various compounds as they move through a multitude of pathways within Earth's system. That's why NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission—scheduled to launch in January 2024—was designed to peer down at Earth from space to see those many forms of carbon in a way no other satellite has done...
Many genes, rather than a 'miracle gene,' are involved in plant resurrection
Some plants can survive months without water, only to turn green again after a brief downpour. A recent study by the Universities of Bonn and Michigan shows that this is not due to a "miracle gene." Rather, this ability is a consequence of a whole network of genes, almost all of which are also present in more vulnerable varieties. The results have already appeared online in The Plant Journal.
