GSA's dynamic online journal, Geosphere, posts articles online regularly. Locations and topics studied this month include the Moine thrust zone in northwestern Scotland; the Eastern California shear zone; implementation of 'OpenTopography'; the finite evolution of 'mole tracks'; the southern central Andes; the work of International Ocean Discovery Program (IODP) Expedition 351; and the Fairweather fault, Alaska, USA.

The quantum Hall effect traditionally only plays a role in two-dimensional electron systems. Recently, however, a three-dimensional version of the quantum Hall effect was described in the Dirac semimetal ZrTe5.

New evidence shows that short selling has a disciplinary effect on opportunistic insider sales.

The organization of the human genome relies on physics of different states of matter - such as liquid and solid. The findings reveal how the physical nature of the genome changes as cells transform to serve specific functions and point to new ways to potentially better understand disease and to create improved therapies for cancer and genetic disorders.

A team at the NYU Tandon School of Engineering has advanced a critical step in fabrication of Perovskite solar cells: p-type doping of organic hole-transporting materials within the cells. The research, "CO2 doping of organic interlayers for perovskite solar cells," appears in Nature.

A new formula from Army scientists is leading to new insights on how to build an energy-efficient legged teammate for dismounted warfighters.

A new study by University of Alberta researchers sheds light on why many COVID-19 patients, even those not in hospital, are suffering from hypoxia--a potentially dangerous condition in which there is decreased oxygenation in the body's tissues. The study also shows why the anti-inflammatory drug dexamethasone has been an effective treatment.

When reaping benefits from environmental and social activities, not all firms are created equal. Tangible asset-intensive industries do better than intangibles-heavy ones, SMU research has found.

Researchers have demonstrated "giant flexoelectricity" in soft elastomers that could improve robot movement range and make self-powered pacemakers a real possibility.

A new survey looks at the changes prompted by the pandemic at many centers that provide ECT (electroconvulsive therapy) for severe depression and other conditions.

"Lung cancer is the leading cause of cancer-related deaths across the globe with more than 1.7 million deaths annually."

"Head and neck squamous cell carcinomas (HNSCC) are heterogeneous tumors that arise in the upper respiratory tract and are the 6th most common cancer worldwide by incidence."

Upon treating mice systemically with doxorubicin, which induces widespread cellular senescence in vivo, variant 2 increased to a larger extent than variant 1

It's strawberry season in many parts of the U.S, and supermarkets are teeming with these fresh heart-shaped treats. Although the bright red, juicy fruit can grow almost anywhere with lots of sunlight, production in some hot, dry regions is a challenge. Now, researchers reporting in ACS' Journal of Agricultural Food and Chemistry have identified five cultivars that are best suited for this climate, which could help farmers and consumers get the most fragrant, sweetest berries.

The myriad processes occurring in biological cells may seem unbelievably complex at first glance. And yet, in principle, they are merely a logical succession of events, and could even be used to form digital circuits. Researchers have now developed a molecular switching circuit made of DNA, which can be used to mechanically alter gels, depending on the pH. DNA-based switching circuits could have applications in soft robotics, say the researchers in their article in Angewandte Chemie.

This Topical Issue of EPJ A draws together a large collection of papers inspired by the theory of hot matter and relativistic heavy-ion collisions (THOR) European Cooperation in Science and Technology (COST) Action. Running between November 2016 and April 2021, THOR has provided a way for over 300 researchers involved in heavy-ion collision analysis to freely exchange their ideas.

Researchers from Sinai Health have published a study providing an ultra-detailed look at the organization of a living human cell, providing a new tool that can help scientists around the world better understand what happens during disease.The new study, published in the journal Nature, was conducted in the laboratory of Dr. Anne-Claude Gingras, a senior investigator at the Lunenfeld-Tanenbaum Research Institute and professor in the Department of Molecular Genetics at the University of Toronto.

Nano-sized particles have been engineered in a new way to improve detection of tumors within the body and in biopsy tissue, a research team in Sweden reports. The advance could enable identifying early stage tumors with lower doses of radiation.

Models for professional use were the most effective at retaining aerosol particles of a size equivalent to the novel coronavirus, followed by TNT masks sold in drugstores. The efficacy of fabric masks ranged from 15% to 70%. A tight fit and lack of seams enhanced protection.

The number of specialty behavioral health establishments, their workforce and their wages have increased steadily between 2011 and 2019, according to a new study by Indiana University and University of Michigan researchers.
