A new study, led by University of Minnesota Twin Cities engineering researchers, shows that the stiffness of protein fibers in tissues, like collagen, are a key component in controlling the movement of cells. The groundbreaking discovery provides the first proof of a theory from the early 1980s and could have a major impact on fields that study cell movement from regenerative medicine to cancer research.

Researchers at Cornell have developed a way to analyze how individual immune cells react to the bacteria that cause tuberculosis. It could pave the way for new vaccine strategies and provide insights into fighting other infectious diseases.

To meet an ambitious goal of carbon neutrality by 2045, California's policymakers are relying in part on forests and shrublands to remove CO2 from the atmosphere, but researchers at the University of California, Irvine warn that future climate change may limit the ecosystem's ability to perform this service.

University of Washington researchers have developed a method that uses a gaming graphics card to control plasma formation in their prototype fusion reactor.

Many people find it morally impermissible to put kidneys, children, or doctorates on the free market. But what makes a market transaction morally repugnant in the eyes of the public? And which transactions trigger the strongest collective disapproval? Researchers from the Max Planck Institute for Human Development and the Robert Koch Institute have addressed these questions. Their findings, published in Cognition, offer new entry points for policy interventions.

Hydrogels developed at Rice University mimic intestines when lined with epithelial cells. A study by Rice and Baylor College of Medicine proved hydrogels in various stiffnesses are valuable for learning the dynamics of pathogens that cause diarrhea and other intestinal diseases.

Plastics offer many benefits to society and are widely used in our daily life: they are lightweight, cheap and adaptable. However, the production, processing and disposal of plastics pose a major global threat to the environment and human health. However, researchers at the University of Göttingen have now found a sustainable method - "hydrosetting", which uses water at normal conditions - to process and reshape a new type of hydroplastic polymer. The research was published in Nature Sustainability.

Even at term, gestational age may have an impact on children's academic performance, findings of a new study suggest. The research showed an association between gestational age at term and above-average rankings in a number of academic subjects.

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.

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

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.

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.

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.

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.

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.

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.

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.

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).

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.

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.
