Jiachen Lin, Harvard School of Dental Medicine, Boston, Mass., USA., presented the poster "Burden of Oral Diseases in Emerging Countries: A Prediction Model" 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 a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2021.200030 , Researchers led by Professor Liu Yan from Xidian University, China and Professor Gan Xuetao from Northwestern Polytechnical University, China consider generation and application of the high-Q resonance in all-dielectric metasurfaces.

Transplanting hematopoietic stem cells to treat cancers and other conditions carries with it the risk of developing cardio-cerebrovascular diseases (CCVD)--disorders affecting the blood vessels of the heart and brain. Although research on post-transplant CCVD is extensive, there is paucity of knowledge on the effects of pre-transplant CCVD on transplant outcomes. Now researchers in China suggest pre-transplant CCVD indirectly affects patient mortality and survival following transplant through their strong association with post-transplant CCVD.

The chequered history of the Cambro-Ordovician Alum Shale in northern Europe offers insights into oil and gas formation and traces of life on Mars.

Researchers at ETH Zurich working together with an international team have been able to use seismic data to look inside Mars for the first time. They measured the crust, mantle and core and narrowed down their composition. The three resulting articles are being published together as a cover story in the journal Science.

A new survey of our home galaxy, the Milky Way, combines the capabilities of the Very Large Array and the Effelsberg telescope in Germany to provide astronomers with valuable new insights into how stars much more massive than the Sun are formed.

International consortium, including then IGC, now current ITQB NOVA PI and GREEN-IT member Jörg Becker, offers novel insight into the reproductive evolution of land plants, in new study published in Nature Plants.

After examining nearly the entire human genome for genetic changes that increase risk of aneurysm, researchers discovered a new change in the genetic code of a transcription factor.

German researchers have developed a novel therapeutic approach for resuscitation after cardiac arrest that allows much higher success rates than before - often without neurological complications / Study in Nature Reviews Neuroscience summarizes decisive factors / New „heart-lung machine" makes clinical implementation possible.

In what may be the largest survey of physician attitudes about firearms and how firearm-owning surgeons store guns in their homes, U.S. members of the American College of Surgeons (ACS) said they support the organization taking an active role in advocating for policies and programs designed to lower the risk of firearm-related injuries and deaths.

Scientists at Cambridge and Leeds have successfully reversed age-related memory loss in mice and say their discovery could lead to the development of treatments to prevent memory loss in people as they age.

An international physics team with the participation of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has proposed a new concept that may allow selected cosmic extreme processes to be studied in the laboratory in the future. A special setup of two high-intensity laser beams could create conditions similar to those found near neutron stars, for example. An antimatter jet is generated and accelerated very efficiently, as the experts report in the journal Communications Physics (DOI: 10.1038/s42005-021-00636-x).

Over the last few decades, neurodegenerative diseases became one of the top 10 global causes of death. Researchers worldwide are making a strong effort to understand neurodegenerative diseases pathogenesis, which is essential to develop efficient treatments against these incurable diseases. A team of researchers found out the implication of lysosomes in the spread of Parkinson's disease.

A new study led by researchers from the University of Chicago shows that deep learning models trained on large sets of cancer genetic and tissue histology data can easily identify the institution that submitted the images.

Replication of SARS-CoV-2, the virus responsible for COVID-19, depends on a series of interactions between viral proteins and different cellular partners such as nucleic acids (DNA or RNA). Characterizing these interactions is crucial to elucidate the process of viral replication and identify new drugs for treating COVID-19.

Every drug starts with the search for an active substance targeting disease-related key players. However, there is no perfect drug that affects the one target: no effect without side effects. A group led by Prof. Herbert Waldmann and Dr. Slava Ziegler at the Max Planck Institute of Molecular Physiology in Dortmund has now identified an unexpected effect for a group of characterized active substances: they all modulate cholesterol metabolism, a home-made problem, as it seems.

An innovative testing platform that more closely mimics what cancer encounters in the body may allow for more precise, personalized therapies by enabling the rapid study of multiple therapeutic combinations against tumor cells. The platform, which uses a three-dimensional environment to more closely mirror a tumor microenvironment, is demonstrated in research published in Communications Biology.

It's a favourite first-order for the day, but while a quick coffee may perk us up, new research from the University of South Australia shows that too much could be dragging us down, especially when it comes to brain health.

Silicon, a semi-metal, bonds in its natural form with four other elements and its three-dimensional structure takes the form of a tetrahedron. For a long time, it seemed impossible to achieve the synthesis and characterisation of a two-dimensional equivalent - geometrically speaking, a square. Now scientists from the field of Inorganic Chemistry at Heidelberg University have succeeded in producing a crystalline complex with such a configuration.

The touchscreen technology used in billions of smartphones and tablets could also be used as a powerful sensor, without the need for any modifications.

Using information obtained from around a dozen earthquakes detected on Mars by the Very Broad Band SEIS seismometer, developed in France, the international team of NASA's InSight mission has unveiled the internal structure of Mars. The three papers published on July 23, provide, for the first time, an estimate of the size of the planet's core, the thickness of its crust and the structure of its mantle, based on the analysis of seismic waves reflected and modified by interfaces in its interior.

Based on data for 344 volunteers, Brazilian researchers compared the physical and mental health benefits of workouts led in person by a fitness instructor, unsupervised online sessions, and classes supervised remotely via video call. Gradually increasing intensity was associated with improvements in mental health.
