Biophysicists found an Achilles heel of a cancerogenic virus
2021-04-26
Although most oncological diseases are not infectious, some viruses can cause cancer. According to the World Health Organization, two HPV subtypes account for 70% of cervical cancer cases and pre-existing conditions. Moreover, HPV considerably increases the risks of other types of cancer. Within an infected cell, a viral protein called E6 binds with human proteins from the 14-3-3 family. 14-3-3 proteins are present in cells of all eukaryotic organisms and can interact with hundreds of other important players of intracellular processes to regulate cell division, gene activity, metabolism, cell death, and intracellular ...

Cell adaptation in critically ill could be difference between life and death
2021-04-26
Creating the best conditions for cells to make energy and survive critical illness is a challenge little understood in modern medicine. Now a new study led by scientists at the University of Plymouth, in collaboration with University College London and the Universities of Cambridge and Southampton, shows early signs that cells in some critically ill patients actually adapt to their conditions by producing energy more efficiently.
The research, published in the journal Redox Biology, took muscle and blood samples over seven days from 21 critically ill patients (ie those with two or more organs failing) in intensive care, and 12 healthy people, comparing cells' behaviour.
The study showed that all of the critically ill ...
Shopping online or locally - an individual choice
2021-04-26
The obstacles associated with shopping, such as shipping costs or the time needed to go to the shop, are crucial to the individual choice of where to shop. When deciding between online shopping and local shopping, personal opinion on purchasing security, environmental protection aspects, and work conditions plays a role. This is found by a study using microeconometric models at Karlsruhe Institute of Technology (KIT). Some of the results of the representative study funded by the German Research Foundation are reported in Papers in Applied Geography and Raumforschung und Raumordnung.
For the evaluations reported, data were collected in 2019, that is before local shopping was restricted due to the pandemic. "During the lockdowns, ...

Ozone pollution in germany falls thanks to lower nitrogen oxide emissions
2021-04-26
Summer is the ozone season: The harmful gas forms at ground level on hot, sunny days. In recent years, however, the rise in ozone levels over the summer months has not been as pronounced in Germany as it was previously. According to a new study, this is primarily due to a reduction in nitrogen oxide emissions. This trend can be observed across Germany's southwestern regions in particular, while Berlin lags behind.
Nitrogen oxides (NOx) are among the precursors of ground-level ozone, which can irritate the eyes, nose and throat and aggravate respiratory conditions. The emissions are primarily produced during combustion ...

Discovery of an elusive cell type in fish sensory organs
2021-04-26
KANSAS CITY, MO--One of the evolutionary disadvantages for mammals, relative to other vertebrates like fish and chickens, is the inability to regenerate sensory hair cells. The inner hair cells in our ears are responsible for transforming sound vibrations and gravitational forces into electrical signals, which we need to detect sound and maintain balance and spatial orientation. Certain insults, such as exposure to noise, antibiotics, or age, cause inner ear hair cells to die off, which leads to hearing loss and vestibular defects, a condition reported by 15% of the US adult population. In addition, the ion composition of the fluid surrounding the hair cells needs to be tightly controlled, otherwise ...
Long-term care infrastructure must be re-imagined in a post-pandemic world
2021-04-26
Protecting long-term care residents from outbreaks requires different infrastructure, proper staffing conditions and a culture of quality assurance, researchers have found.
The experts further determined that designing smaller, more homelike spaces would minimize the spread of viruses while promoting better health and quality of life for residents.
"Community outbreaks and lack of personal protective equipment were the primary drivers of outbreak occurrence in long-term care homes, and the built environment was the major determinant of outbreak severity," said George Heckman, a professor in Waterloo's School of Public Health and Health Systems and Schlegel Research Chair in Geriatric Medicine with the Research Institute for Aging.
"We need to distinguish ...
Mapping the path to rewilding: the importance of landscape
2021-04-26
MUNICH -- Rewilding--a hands-off approach to restoring and protecting biodiversity--is increasingly employed across the globe to combat the environmental footprint of rapid urbanization and intensive farming. The recent reintroduction of grey wolves in Yellowstone, America's first national park, is regarded as one of the most successful rewilding efforts, having reinvigorated an ecosystem that had been destabilized by the removal of large predators.
However, successful attempts to rewild the landscape hinge on more than just the reintroduction of a plant or animal species, they also require that geography and geology be taken into account, according to new research from the University of Amsterdam and the Dutch State Forestry Service.
It is the landscape that ultimately ...
New research uncovers continental crust emerged 500 million years earlier than thought
2021-04-26
MUNICH -- The first emergence and persistence of continental crust on Earth during the Archaean (4 billion to 2.5 billion years ago) has important implications for plate tectonics, ocean chemistry, and biological evolution, and it happened about half a billion years earlier than previously thought, according to new research being presented at the EGU General Assembly 2021.
Once land becomes established through dynamic processes like plate tectonics, it begins to weather and add crucial minerals and nutrients to the ocean. A record of these nutrients is preserved in the ancient rock record. Previous research used strontium isotopes in marine carbonates, but these rocks are usually scarce ...
Scientists have cultured the first stable coral cell lines
2021-04-26
Researchers have successfully grown cells from the stony coral, Acropora tenuis, in petri dishes
The cell lines were created by separating out cells from coral larvae, which then developed into eight distinct cell types
Seven out of eight cell types were stable and could grow indefinitely, remaining viable even after freezing
Some of the cell types represented endoderm-like cells, and could therefore shed light on how coral interacts with photosynthesizing algae and how bleaching occurs
The cell lines could be used in many avenues ...
3D holographic head-up display could improve road safety
2021-04-26
Researchers have developed the first LiDAR-based augmented reality head-up display for use in vehicles. Tests on a prototype version of the technology suggest that it could improve road safety by 'seeing through' objects to alert of potential hazards without distracting the driver.
The technology, developed by researchers from the University of Cambridge, the University of Oxford and University College London (UCL), is based on LiDAR (light detection and ranging), and uses LiDAR data to create ultra high-definition holographic representations of road objects which are beamed directly to the driver's eyes, instead of 2D windscreen projections used in most head-up displays.
While the technology has not yet been ...
