Optical sensors can quantitatively analyze chemical and biological samples by measuring and processing the optical signals produced by the samples. Optical sensors based on infrared absorption spectroscopy can achieve high sensitivity and selectivity in real time, and therefore play a crucial role in a variety of application areas such as environmental sensing, medical diagnostics, industrial process control and homeland security.
TORONTO, Jan. 13, 2021 - Close to 5,700 lakes in the Northern Hemisphere may permanently lose ice cover this century, 179 of them in the next decade, at current greenhouse gas emissions, despite a possible polar vortex this year, researchers at York University have found.
Those lakes include large bays in some of the deepest of the Great Lakes, such as Lake Superior and Lake Michigan, which could permanently become ice free by 2055 if nothing is done to curb greenhouse gas emissions or by 2085 with moderate changes.
SILVER SPRING, Md.--A new study confirms that treatment with Bimagrumab, an antibody that blocks activin type II receptors and stimulates skeletal muscle growth, is safe and effective for treating excess adiposity and metabolic disturbances of adult patients with obesity and type 2 diabetes.
HOUSTON - (Jan. 13, 2021) - Pyrolyzed plastic ash is worthless, but perhaps not for long.
Rice University scientists have turned their attention to Joule heating of the material, a byproduct of plastic recycling processes. A strong jolt of energy flashes it into graphene.
The technique by the lab of Rice chemist James Tour produces turbostratic graphene flakes that can be directly added to other substances like films of polyvinyl alcohol (PVA) that better resist water in packaging and cement paste and concrete, dramatically increasing their compressive strength.
Wetlands are the dominant natural source of atmospheric methane, a potent greenhouse gas which is second only to carbon dioxide in its importance to climate change. Anthropogenic climate change is expected to enhance methane emissions from wetlands, resulting in further warming. However, wetland methane feedbacks were not fully assessed in the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report, posing a challenge to meeting the global greenhouse gas mitigation goals set under the Paris Agreement.
People worldwide want their coffee to be both satisfying and reasonably priced. To meet these standards, roasters typically use a blend of two types of beans, arabica and robusta. But, some use more of the cheaper robusta than they acknowledge, as the bean composition is difficult to determine after roasting. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have developed a new way to assess exactly what's in that cup of joe.
DURHAM, N.C. -- Biomedical engineers at Duke University have devised an algorithm to remove contaminated microbial genetic information from The Cancer Genome Atlas (TCGA). With a clearer picture of the microbiota living in various organs in both healthy and cancerous states, researchers will now be able to find new biomarkers of disease and better understand how numerous cancers affect the human body.
Many students, especially non-science majors, dread chemistry. The first lesson in an introductory chemistry course typically deals with how to interpret the periodic table of elements, but its complexity can be overwhelming to students with little or no previous exposure. Now, researchers reporting in ACS' Journal of Chemical Education introduce an innovative way to make learning about the elements much more approachable -- by using "pseudo" periodic tables filled with superheroes, foods and apps.
On April 15, 2020, a brief burst of high-energy light swept through the solar system, triggering instruments on several NASA and European spacecraft. Now, multiple international science teams conclude that the blast came from a supermagnetized stellar remnant known as a magnetar located in a neighboring galaxy.
This finding confirms long-held suspicions that some gamma-ray bursts (GRBs) - cosmic eruptions detected in the sky almost daily - are in fact powerful flares from magnetars relatively close to home.
KANSAS CITY, MO--What if the degenerative eye conditions that lead to glaucoma, corneal dystrophy, and cataracts could be detected and treated before vision is impaired? Recent findings from the lab of Investigator Ting Xie, PhD, at the Stowers Institute for Medical Research point to the ciliary body as a key to unlocking this possibility.
TROY, N.Y. -- Blood sample analysis showed that, two to five years after they gave birth, mothers of children with autism spectrum disorder (ASD) had several significantly different metabolite levels compared to mothers of typically developing children. That's according to new research recently published in BMC Pediatrics by a multidisciplinary team from Rensselaer Polytechnic Institute, Arizona State University, and the Mayo Clinic.
Skoltech researchers have found a way to use chemical sensors and computer vision to determine when grilled chicken is cooked just right. These tools can help restaurants monitor and automate cooking processes in their kitchens, and perhaps one day even end up in your 'smart' oven. The paper detailing this research results, supported by a Russian Science Foundation grant, was published in the journal Food Chemistry.
Scientists tame photon-magnon interaction.
Working with theorists in the University of Chicago’s Pritzker School of Molecular Engineering, researchers in the U.S. Department of Energy’s (DOE) Argonne National Laboratory have achieved a scientific control that is a first of its kind. They demonstrated a novel approach that allows real-time control of the interactions between microwave photons and magnons, potentially leading to advances in electronic devices and quantum signal processing.
New research from King's College London shows nearly half of Intensive Care Unit (ICU) staff are likely to meet the threshold for PTSD, severe anxiety or problem drinking during the COVID-19 pandemic.
Results from a study of ICU healthcare workers, published today in Occupational Medicine, shows the stark impact of working in critical care during the COVID-10 pandemic. The researchers found poor mental health was common in many ICU clinicians although they were more pronounced in nurses than in doctors or other healthcare professionals.
New Rochelle, NY, January 12, 2021--The Academy of Breastfeeding Medicine (ABM) does not recommend cessation of breastfeeding for individuals who are vaccinated against COVID-19. In a new statement, the ABM suggests that lactating women discuss the risks and benefits of vaccination with their health care provider, within the context of their risk of contracting COVID-19 and of developing severe disease, according to the peer-reviewed journal Breastfeeding Medicine.
