Irvine, Calif., July 22, 2021 - To meet an ambitious goal of carbon neutrality by 2045, California's policymakers are relying in part on forests and shrublands to remove CO2 from the atmosphere, but researchers at the University of California, Irvine warn that future climate change may limit the ecosystem's ability to perform this service.
Houston Methodist Neurological Institute researchers from the department of neurosurgery shrunk a deadly glioblastoma tumor by more than a third using a helmet generating a noninvasive oscillating magnetic field that the patient wore on his head while administering the therapy in his own home. The 53-year-old patient died from an unrelated injury about a month into the treatment, but during that short time, 31% of the tumor mass disappeared. The autopsy of his brain confirmed the rapid response to the treatment.
Alexandria, Va., USA - IADR President Pamela Den Besten presented and chaired the IADR President's Symposium "Enamel Defects as Biomarkers for Exposure to Environmental Stressors" at the virtual 99th General Session & Exhibition of the International Association for Dental Research (IADR), held in conjunction with the 50th Annual Meeting of the American Association for Dental Research (AADR) and the 45th Annual Meeting of the Canadian Association for Dental Research (CADR), on July 21-24, 2021.
Remote 24-hour monitoring for cancer patients receiving chemotherapy helps to better manage side effects and improve quality of life, finds a study published by The BMJ today.
The researchers say remote monitoring can provide a safe, secure, and "real time" system that optimises symptom management and supports patients to remain at home - and is particularly relevant in the context of the covid-19 pandemic.
Alexandria, Va., USA - Parach Sirivichayakul, Mahidol University, Bangkok, Thailand, presented the poster "Preventing Approximal Caries in Primary Teeth With Topical Fluorides" at the virtual 99th General Session & Exhibition of the International Association for Dental Research (IADR), held in conjunction with the 50th Annual Meeting of the American Association for Dental Research (AADR) and the 45th Annual Meeting of the Canadian Association for Dental Research (CADR), on July 21-24, 2021.
In the United States, climate change is controversial, which makes communicating about the subject a tricky proposition.
A recent study by Portland State researchers Brianne Suldovsky, assistant professor of communication, and Daniel Taylor-Rodriguez, assistant professor of statistics, explored how liberals and conservatives in Oregon think about climate science to get a better sense for what communication strategies might be most effective at reaching people with different political ideologies. The study was published in Climatic Change in June.
Since buildings consume 75% of electricity in the U.S., they offer great potential for saving energy and reducing the demands on our rapidly changing electric grid. But how much, where, and through which strategies could better management of building energy use actually impact the electricity system?
Aryl sulfide, an aromatic compound in which sulfur is attached to an aryl (a functional group derived from an aromatic ring), is found in biologically active materials effective against asthma, Alzheimer's disease, and cancer. As a result, chemists have shown a lot of interest in synthesizing aryl sulfides. Traditionally, carbon-sulfur (C-S) bond formation reactions between thiols and aryl electrophiles catalyzed by transition metals have been employed for aryl sulfide synthesis because of their high reliability. However, thiols have an unpleasant smell and are toxic.
Nanomaterials have been used in a variety of emerging applications, such as in targeted pharmaceuticals or to bolster other materials and products such as sensors and energy harvesting and storage devices. A team in the McKelvey School of Engineering at Washington University in St. Louis is using nanoparticles as heaters to manipulate the electrical activity of neurons in the brain and of cardiomyocytes in the heart.
The tiny organisms living in soil may have a greater effect on the yield and pest and disease resistance of crop plants grown in that soil than previously known.
No one wants bad breath -- not when visiting friends and family, at a job interview, and especially not on a first date. Smelly breath can make things awkward, but it also is a natural warning sign, indicating that serious dental issues are occurring. Now, researchers reporting in ACS Nano have constructed a portable, thumb-sized device that diagnoses bad breath by quickly "sniffing" exhalations for the gas that makes it stinky -- hydrogen sulfide.
ITHACA, N.Y. - Cornell researchers have developed nanostructures that enable record-breaking conversion of laser pulses into high-harmonic generation, paving the way for new scientific tools for high-resolution imaging and studying physical processes that occur at the scale of an attosecond - one quintillionth of a second.
In the race to combat climate change, capturing carbon dioxide (CO2) emissions has been touted as a simple road to reach net-zero emissions by 2050. While the science behind carbon capture is sound, current technologies are expensive and not optimized for all settings. A cover story in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, highlights the current state of carbon capture and work being done to improve the process.
Domesticated rabbits come in all sizes and colors, including tiny Netherland Dwarfs, floppy-eared French lops, Flemish Giants, and fluffy Angoras.
These breeds belong to Europe's only rabbit species, originally limited to the Iberian Peninsula and Southern France and used for meat and fur since the last Ice Age, culminating in domestication about 1,500 years ago.
A new University of Chicago study has found that the drug masitinib may be effective in treating COVID-19.
The drug, which has undergone several clinical trials for human conditions but has not yet received approval to treat humans, inhibited the replication of SARS-CoV-2 in human cell cultures and in a mouse model, leading to much lower viral loads.
