There is, however, another type of interaction that objects can have with light which can reveal some important information and show rich features. This is the speeding up or slowing down of the light that passes through, which is shown as phase. The other option can be a simple ‘single pixel’ detector, which can only see how much light is gathered and cannot give you any spatial information. This, in fact, was the method of use before the development of the more sensitive cameras and what the team exploited in order to detect phase information. Our approach allows us to see all of this with just a single pixel detector,” says Forbes.
When cells divide, telomeres shorten, eventually becoming so short that the cell can no longer divide properly, leading to cell death. Al-Turki and Griffith note in their paper a striking similarity of this RNA to the RNA generated from human telomeres, and they hypothesized that the same novel mechanism might be in play. But occasionally scientists have failed to put observations from two very distant fields together and that’s what we did. Discovering that telomeres encode two novel signaling proteins will change our understanding of cancer, aging, and how cells communicate with other cells. The UNC Viral Vector Core and the light microscopy facility at the UNC Lineberger Comprehensive Cancer Center were vital partners in this research.1 month ago EurekAlert!
“We are really struggling with maintaining effective therapeutic options for high-risk patients with COVID-19,” says Adit Ginde, MD, professor of emergency medicine at the University of Colorado School of Medicine. Right now, the only two effective antiviral treatment options are Paxlovid and Remdesivir. So, Ginde and a team of researchers swung into action to determine if Paxlovid is effective against Omicron variants B.4 and B.5. “If we can confirm benefits of a therapy, clinicians can be confident in prescribing a treatment, and patients can feel comfortable receiving treatment. He said, “The laboratory data suggest that Paxlovid is still effective at neutralizing the virus in recent Omicron subvariants.1 month ago EurekAlert
In this light, a research team led by Professor Yun Hak Kim from Pusan National University, South Korea, explored the role of sunlight exposure in the prevalence of suicide. Additionally, while the suicide prevalence in men (25.91) was much higher than in women (5.66), women were likely to have suicidal tendencies at a higher frequency. They also noted that while gun-control and gun-permissive countries had similar suicide prevalence values of 16.46 and 15.40, suicide by firearm was more common in the latter. ***ReferenceDOI: https://doi.org/10.1016/j.ajp.2023.103454Authors: Seongjun Ana1, Sungju Lima1, Hyun-Woo Kim2, Hyung-Sik Kim3, Dongjun Lee4, Eunjeong Son5, Tae Woo Kim6, Tae Sik Goh7, Kihun Kim8, Yun Hak Kim9,10,Affiliations:1School of Medicine, Pusan National University2Department of Neurology, Pusan National University Yangsan Hospital3Department of Oral Biochemistry, Dental and Life Science Institute, School of Dentistry, Pusan National University4Department of Convergence Medicine, School of Medicine, Pusan National University5Division of Pulmonary, Allergy, and Critical Care Medicine, Department of Internal Medicine, Pusan National University Yangsan Hospital6Department of Orthopaedic Surgery, Pusan National University Yangsan Hospital7Department of Orthopaedic Surgery, Pusan National University8Department of Occupational and Environmental Medicine, Kosin University Gospel Hospital9Department of Biomedical Informatics, School of Medicine, Pusan National University10Department of Anatomy, School of Medicine, Pusan National UniversityAbout Pusan National UniversityPusan National University, located in Busan, South Korea, was founded in 1946, and is now the No. Website: https://www.pusan.ac.kr/eng/Main.doAbout Professor Yun Hak Kim from Pusan National UniversityDr. Yun Hak Kim is an Associate Professor at the Department of Anatomy and the Department of Biomedical Informatics at Pusan National University (PNU).1 month ago EurekAlert
The accomplishments of the 2022 ACM Fellows make possible the computing technologies we use every day. The ACM Fellows program recognizes the top 1% of ACM Members for their outstanding accomplishments in computing and information technology and/or outstanding service to ACM and the larger computing community. The ACM Fellows program is a way to recognize the women and men whose hard work and creativity happens inconspicuously but drives our field. Additional information about the 2022 ACM Fellows, as well as previously named ACM Fellows, is available through the ACM Fellows website. About the ACM Recognition ProgramThe ACM Fellows program, initiated in 1993, celebrates the exceptional contributions of the leading members in the computing field.2 months ago EurekAlert
A new publication from Opto-Electronic Advances, 10.29026/oea.2022.210105 discusses other pathways towards a more sustainable electrocatalyst for efficient hydrogen technology. Mostly, the electrochemical fuel generation for hydrogen and oxygen is carried out through the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER), respectively. The precise and controlled fabrication of LIPSS on electrodes could significantly improve their performance as a sustainable electrocatalyst for efficient hydrogen generation. His work has appeared in journals such as Nature Photonics, Nature Nanotechnology, Nature Review Materials, Nature Communications, Nature Materials, Science, Joule, Nano Letters, PRL, and Light: Science & Applications. His research has been widely covered in the media, including Phys.org, Science Daily, Science Beta, IEEE Spectrum, Nature Materials, CE& News, Science, Science News, and the BBC.2 months ago EurekAlert
The outbreak reflects low population immunity due to low rates of vaccination against smallpox; smallpox and monkeypox viruses are both orthopoxviruses. Despite the low reported rates in children so far, there are special concerns about complications and other serious outcomes of monkeypox in children. Because routine smallpox vaccination was discontinued after smallpox was eradicated – 1972 in the United States – many people have never been vaccinated.

“The challenge is the haystack of possible reaction conditions is astronomical, and the needle is hidden somewhere inside. By leveraging the power of artificial intelligence and building-block chemistry to create a feedback loop, we were able to shrink the haystack. However, general reaction conditions to make the automated process broadly applicable have remained elusive. “Traditionally, chemists customize the reaction conditions for each product they are trying to make,” Burke said. The paper “Closed-loop optimization of general reaction conditions for heteroaryl Suzuki-Miyaura coupling” is available online.5 months ago EurekAlert!
