A team from Fudan University, the Shanghai Institute of Technical Physics, the Beijing University of Posts and Telecommunications and Shaoxin Laboratory, all in China, has developed a retinal prosthesis woven from metal nanowires that partially restored vision in blind mice.
While kelp forests persist along northern Maine's rocky coast, kelp abundance has declined by as much as 80% on the southern coast in recent decades. In its stead, carpet-like turf algae have moved in.
As demand for advanced polymeric materials increases, post-functionalization has emerged as an effective strategy for designing functional polymers. This approach involves modifying existing polymer chains by introducing new chemical groups after their synthesis, allowing for the transformation of readily available polymers into materials with desirable properties.
When DNA breaks inside the cell, it can spell disaster, especially if the damage occurs in areas of the genome that are difficult to repair. Now, scientists Irene Chiolo and Chiara Merigliano at the USC Dornsife College of Letters, Arts and Sciences have discovered that a protein called Nup98, long known for helping traffic molecules in and out of the cell's nucleus, plays another surprising role: guiding the cell's most delicate repairs and reducing the risk of genetic mistakes that can lead to cancer. Their findings were published in Molecular Cell.
When visiting the dentist, you might remember being poked and prodded by a thin metal instrument to check your teeth and gums. This technique, called periodontal probing, is used to look for signs of gum disease. Now, researchers publishing in ACS Sensors report a toothbrush-shaped ultrasound transducer that can provide a less invasive screening for gum disease. In proof-of-concept demonstrations on animal tissues, the device produced measurements similar to those of a manual probe.
Giant viruses play a role in the survival of single-celled marine organisms called protists. These include algae, amoeba, and flagellates, that form the base of ocean food webs. And since these protists form an important part of the food chain, these large DNA viruses are often responsible for various public health hazards, including harmful algal blooms.
Food scientists at the University of Illinois Urbana-Champaign identified the optimal fermentation conditions for pulses ― the dried edible seeds of legumes ― that increased their antioxidant and antidiabetic properties and their soluble protein content.
With careful planning and a little luck, researchers found a surprising upside to hurricanes after a Category 4 storm disrupted their expedition off the coast of Mexico.
A team of paleontologists affiliated with several institutions in Argentina, working with a colleague from the U.K., has discovered evidence of scales from lepidopterans in dung samples recovered from a dig site in Talampaya National Park, Argentina. In their paper published in the Journal of South American Earth Sciences, the group describes how they found the scales in the dung samples and what the find means for scientists who study butterflies and moths.
A study by Dr. Joosje van Bennekom and her colleagues aimed to determine the provenance of the famed silver basin supposedly made of Spanish treasure fleet silver captured by the Dutch West India Company (WIC) in 1628. The work is published in the Journal of Cultural Heritage.
This week, Chinese researchers reported a nearly complete skull representing the first known sauropod species from East Asia. A team at the USDA identified viruses from a miticide-resistant parasitic mite causing honey bee colony collapses. And archaeologists report that the Philippines had a technologically advanced maritime culture 35,000 years ago.
For years, astronomers have predicted a dramatic fate for our galaxy: a head-on collision with Andromeda, our nearest large galactic neighbor. This merger—expected in about 5 billion years—has become a staple of astronomy documentaries, textbooks and popular science writing.
Chagas disease is often called a silent killer because many people don't realize they have it until complications from the infection kill them.
Within the animal kingdom, a naturally produced molecule known as itaconate serves a prominent role in the immune system as a defensive agent against viruses and inflammation. Itaconate is classified as a metabolite, a natural compound that arises when organisms convert food into energy.
The reliable manipulation of the speed at which light travels through objects could have valuable implications for the development of various advanced technologies, including high-speed communication systems and quantum information processing devices. Conventional methods for manipulating the speed of light, such as techniques leveraging so-called electromagnetically induced transparency (EIT) effects, work by utilizing quantum interference effects in a medium, which can make it transparent to light beams and slow the speed of light through it.
