Fukuoka, Japan—In organic molecules an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge). They are held together by Coulombic attraction and can move within molecular assemblies. Singlet fission (SF) is a process where an exciton is amplified, and two triplet excitons are generated from a singlet exciton. This is caused by the absorption of a single particle of light, or photon, in molecules called chromophores (molecules that absorb specific wavelengths of light). Controlling the molecular orientation and arrangement of chromophores is crucial for achieving high SF efficiency in materials with strong potential for optical ...

About The Study: In this cohort study, smoking and cardiovascular disease (CVD) risk exhibited a dose-dependent association, with light ex-smokers having a CVD risk similar to that of never-smokers relatively soon after smoking cessation. For heavy ex-smokers, greater than 25 years might be required for the residual CVD risk to align with that of never-smokers.  Corresponding Author: To contact the corresponding author, Seung Yong Shin, MD, PhD, email theshin04@korea.ac.kr.

Cratons are fascinating yet enigmatic geological formations. Known to be relatively stable portions of the Earth’s continental crust, cratons have remained largely unchanged for billions of years. Although cratons have survived many geological events, some are undergoing decratonization—a process characterized by their deformation and eventual destruction. For example, the North China Craton (NCC), an ancient continental crust block, is known to have begun extensive decratonization during the Mesozoic era, largely due to tectonic and geochemical modifications and destabilization of its base (or ‘keel’). However, explaining the mechanisms ...

Despite ongoing efforts to curb CO2 emissions with electric and hybrid vehicles, other forms of transportation remain significant contributors of greenhouse gases.

Now, researchers reporting in ACS Sustainable Chemistry & Engineering have used computer modeling to study the feasibility and challenges of hydrogen-powered aviation. “While there is a long way to go for hydrogen aviation to be realized at scale, we hope that our ...

Socioeconomic factors such as education, occupation, and wealth influence the likelihood of developing cognitive impairment or dementia in later life and whether a person is likely to recover, finds a new study led by UCL researchers. The research, published in Scientific Reports, followed 8,442 adults aged 50 and above in England over 10 years from 2008/09 to 2018/19, to examine how socioeconomic factors at the start of the study were associated with changes in cognitive status. The researchers tracked how these people moved between various states: healthy, mild cognitive impairment, and dementia. They also considered the possibility ...

Getting to the heart of causality is central to understanding the world around us. What causes one variable — be it a biological species, a voting region, a company stock, or a local climate — to shift from one state to another can inform how we might shape that variable in the future.  But tracing an effect to its root cause can quickly become intractable in real-world systems, where many variables can converge, confound, and cloud over any causal links.  Now, a team of MIT engineers hopes to provide some clarity in the pursuit of causality. They developed ...

About The Study: This article discusses a recent revision of the Alzheimer Association criteria to define Alzheimer disease (AD) as a purely biological entity, which raises concerns that if diagnosis of AD can be reduced to the sole presence of AD core 1 biomarkers, major uncertainty and variability in the clinical prognosis of patients diagnosed with AD may be introduced.

With the rapid increase in the global population, a "protein crisis" is expected in the near future, where the supply of protein will not be able to meet the rising demand. Fishmeal is the most common protein source that supports the production of livestock and aquaculture products, which are key protein sources for human consumption. However, global shortage of fishmeal and its rising prices have created an urgent need to find and secure an alternative protein source. Insects are gaining attention as novel protein sources ...

Most women use medication during pregnancy. Yet, selecting appropriate drugs and doses is challenging. In a new The Lancet article, physicians and researchers from the Radboud university medical center, Maastricht UMC+, Imperial College London, and the University of Liverpool introduce a shared decision-making approach combining ethical principles and a pregnant woman’s values with existing evidence. They use the example of sertraline, a commonly prescribed antidepressant in pregnancy, to illustrate the advocated decision-making process. Although pregnant women often need medication, data on drug safety and efficacy in pregnancy remains limited. Historically seen as vulnerable research ...

Macrophage cells are the immune system’s frontline soldiers, early on the scene to protect the body from foreign invaders. These cells answer the immune system's critical question for the rest of its troops: friend or foe?  As critical responders, macrophages can perceive helpful biotechnology as threats. If not created with the right materials or mechanical forces, these devices can trigger an immune response that can cause inflammation, scar tissue or device failure. But what is the right material or the right mechanical force? In a meta-analysis co-led ...

Beyond colorful coral reefs and diverse nearshore ecosystems, Pacific Ocean waters surrounding the Hawaiian Islands have comparatively little marine life and low biological productivity. New research published by University of Hawai‘i (UH) at Mānoa oceanographers showed that eddies on the leeward side of the Hawaiian Islands can supply nutrients, not only locally, but also to the opposite side of the island chain and stimulate blooms of phytoplankton, microscopic plant life that lives in the surface ocean.  The study, published in JGR Oceans, was selected by the American Geophysical Union’s editorial board as a featured article. “While ...
