Professor Joon Won Park's research team at POSTECH reveals the structure of a hetero-oligomer nano-aggregate - a substance that causes Parkinson's and dementia - through quadruple force mapping.

Researchers are finding new details on the complex dynamics involved in how organisms sense an infection from pathogens. The researchers found that worms can sense changes in their metabolism in order to unleash protective defenses, even if they don't directly sense an incursion from pathogens.

Many eye diseases are associated with a restricted blood supply, known as ischaemia, which can lead to blindness. The role of the protein tenascin-C, an extracellular matrix component, in retinal ischaemia was investigated in mice by researchers from Ruhr-Universität Bochum (RUB). They showed that tenascin-C plays a crucial role in damaging the cells responsible for vision following ischaemia. The results were published online by the team in the journal Frontiers in Neuroscience on 20 May 2021.

When researchers at ETH Zurich compared the reference genomes between several breeds of domestic cattle and closely related wild cattle, they discovered genes with previously unknown functions.

A new report finds small modular reactors could provide competitively priced electricity in Washington state's future electricity market.

The frequent and strong dust storms in northern China have attracted wide attentions. Yet the long-term dust storm activities and their responses to natural climatic forcing and/or human activities are not fully understood. Researchers in Tianjin University, China, and colleagues presented histories of annual/decadal dust storm variations of the past few hundred years using high resolution sedimentary grainsize records from Lake Karakul and Lake Daihai, northern China (Fig. 1), and discussed the potential forcing mechanisms.

New diagnostic technique could help contain the spread of COVID-19 and other viral outbreaks.

Hubble parameter describes the expansion rate of the present universe. The current measurements from high redshift cosmic microwave background and low redshift supernovae distance ladder show a significant discrepancy. A new independent measurement whose accuracy is better than 2% is crucial. Gravitational waves from compact binary coalescence open a completely novel observational window. Chinese scientists find that the future space-borne gravitational wave observatories will be able to constrain the Hubble parameter within 1% level.

Danish one-year-olds carry several hundred antibiotic resistant genes in their bacterial gut flora according to a new study from the University of Copenhagen. The presence of these genes is partly attributable to antibiotic use among mothers during pregnancy.

The new approaches have already unearthed a treasure trove of useful data -- and they're now being made available for free.

UC San Francisco researchers have found a way to double doctors' accuracy in detecting the vast majority of complex fetal heart defects in utero - when interventions could either correct them or greatly improve a child's chance of survival - by combining routine ultrasound imaging with machine-learning computer tools.

The Tsimane indigenous people of the Bolivian Amazon experience less brain atrophy than their American and European peers. The decrease in their brain volumes with age is 70% slower than in Western populations.

The farming of livestock to feed the global appetite for animal products greatly contributes to global warming. A new study however shows that emission intensity per unit of animal protein produced from the sector has decreased globally over the past two decades due to greater production efficiency, raising questions around the extent to which methane emissions will change in the future and how we can better manage their negative impacts.

People who eat too many refined carbs and fatty meats for dinner have a higher risk of heart disease than those who eat a similar diet for breakfast, according to a nationwide study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.

A new paper that has been accepted for publication in Ophthalmic & Physiological Optics, the peer-reviewed journal of The College of Optometrists (UK), furthers understanding of myopia control efficacy in the context of normal childhood eye growth. Axial Length Targets for Myopia Control (Chamberlain P, et al.) is now available online via Open Access.

Time not only flies when you're having fun - sometimes anticipating a fun event makes it feel like it will be over as soon as it begins, a new study suggests.Researchers found that people judge future positive events as being both farther away as well as shorter in duration than negative or neutral events.

Tobacco use continues to be a primary contributor to the global burden of disease, causing an estimated 12% of deaths worldwide among people aged 30 and over. Four leading cardiovascular organizations - American Heart Association, American College of Cardiology, European Society of Cardiology and World Heart Federation - today released a joint opinion calling for greater action at the global scale to end the tobacco epidemic once and for all.

Social isolation and quarantine can have a detrimental impact on physical and mental health of people living with pre-existing conditions, according to two studies being presented at the 23rd European Congress of Endocrinology (e-ECE 2021) on Wednesday 26 May at 14:14 CET (www.ece2021.org).

The biological clock is present in almost all cells of an organism. As more and more evidence emerges that clocks in certain organs could be out of sync, there is a need to investigate and reset these clocks locally. Scientists from the Netherlands and Japan introduced a light-controlled on/off switch to a kinase inhibitor, which affects clock function. This gives them control of the biological clock in cultured cells and explanted tissue.

What information is retained in a memory over time, and which parts get lost? These questions have led to many scientific theories over the years, and now a team of researchers at the Universities of Glasgow and Birmingham have been able to provide some answers.
