The creation of a silica nanocapsule could allow treatments that use light to destroy cancerous or precancerous cells in the skin to also be used to treat other types of cancer. Such are the findings of a study by INRS (Institut national de la recherche scientifique) professors Fiorenzo Vetrone and Federico Rosei, in collaboration with an international research team. Their results have been published in an article featured on the cover of the 26th edition of the Royal Society of Chemistry journal Chemical Science.
The UK's universities are struggling to live up to the spirit and ambition of the Modern Slavery Act, hampered by poor oversight of their supply chains, a lack of skills and resource in supply chain management, a focus on reducing costs, and lacklustre engagement from many in senior management, a new study from the University of Bath shows.
Mechanical engineering associate professor Jiangtao Cheng and electrical and computer engineering assistant professor Wei Zhou have developed an ultrasensitive biosensing method that could dramatically shorten the amount of time required to verify the presence of the COVID-19 virus in a sample. Their peer-reviewed research was published in ACS Nano on June 29.
In their quest to find new drugs to treat deadly diseases, scientists study millions of molecules at high speed at the same time. Often it is enzymes that are investigated as targets in these 'high-throughput' screenings.
Delays to cancer referral through reduced use of the urgent GP referral pathway during the coronavirus pandemic could result in more than a thousand additional deaths in England, a new study reports.
New modelling suggests that delays in patients presenting and being referred with suspected cancer by their GP, and resulting bottlenecks in diagnostic services, are likely to have had a significant adverse effect on cancer survival.
Spiral galaxies such as our Milky Way can have sprawling magnetic fields. There are various theories about their formation, but so far the process is not well understood. An international research team has now analysed the magnetic field of the Milky Way-like galaxy NGC 4217 in detail on the basis of radio astronomical observations and has discovered as yet unknown magnetic field structures. The data suggest that star formation and star explosions, so-called supernovae, are responsible for the visible structures.
This image shows the huge extent of a spiral galaxy's magnetic field. The galaxy NGC 4217 is a star-forming, spiral galaxy, similar to our own Milky Way, 67 million light-years from Earth in the constellation Ursa Major. The galaxy is seen edge-on in a visible-light image from the Sloan Digital Sky Survey and Kitt Peak National Observatory, and the magnetic field lines, shown as green, are revealed by the National Science Foundation's Karl G. Jansky Very Large Array (VLA) radio telescope.
Tropical Depression 8E developed on July 20 and quickly organized into a tropical storm. Infrared NASA satellite imagery revealed that Tropical Storm Douglas contained strong storms and showed banding of thunderstorms around its center.
Tropical Depression 8E formed about 905 miles (1,460 km) southwest of the southern tip of Baja California, Mexico by 11 a.m. EDT on July 20. Within 12 hours, 8E had strengthened into a tropical storm and was renamed Douglas.
The nutritional benefit of rice and sugar distributed by a national food subsidy programme in India may be limited, says new research published today.
India's main food subsidy program, the Public Distribution System (PDS) provides sugar, rice, and wheat to households at reasonably low costs to improve their nutrition intake and attain food security.
Although the programme aims to improve nutritional outcomes through its subsidies, the research team saw no evidence of improvements when children received subsidized rice and sugar.
Tension while waiting for test results, the fear of not making it, the feeling of being under pressure, apprehension: these emotional states often come with physical illnesses like backache, headache, nausea, tachycardia, tremors, difficulty breathing, dizziness. These illnesses, which vary in intensity and duration, are all associated with anxiety, which includes a variety of disorders. While there is no definite cure for anxiety, neuro-scientific research is making progress to develop new diagnostic tools and more efficient treatments.
ITHACA, N.Y. - A collaboration between researchers from Cornell University, Northwestern University and University of Virginia combined complementary imaging techniques to explore the atomic structure of human enamel, exposing tiny chemical flaws in the fundamental building blocks of our teeth. The findings could help scientists prevent or possibly reverse tooth decay.
Bringing a little bit of science fiction into an operating room, a team of engineers and physicians at Washington University in St. Louis has shown for the first time that using a holographic display improves physician accuracy when performing a procedure to treat irregular heartbeat.
Fighting cancer often means employing a suite of techniques to target the tumor and prevent it from growing and spreading to other parts of the body. It's no small feat -- the American Cancer Society predicts roughly 1.8 million new cases of cancer in the country in 2020, underscoring the need to identify additional ways to outsmart the runaway cells.
New analysis shows that while the survivability of wounds on the battlefield has steadily improved for United States service members since World War II, there were several increases that bucked that trend during subsequent conflicts. By understanding these bumps and making steps to improve readiness between conflicts, troops' lives could be saved in the future. These insights were published in a special supplement of the Journal of Trauma and Acute Care Surgery focusing on the military.
A new analysis of SARS-CoV-2 transmission data in China shows that faster identification and isolation of infected, symptomatic individuals contributed to the shortening of the average serial interval - or the period between the onset of symptoms in successive cases - over time, as fewer opportunities occurred for viral transmission from one infector to more individuals. Importantly, changes in average serial intervals in this study reflect the efficacy of case isolation, the researchers demonstrate, rather than indicating modified virulence or incubation times.
