Lack of staff, funds and tools: health officials worry the US isn’t ready for Covid vaccines

Experts are frustrated after months of inconsistent information and concerned that a mass vaccination plan will stumbleMillions of Americans are counting on a Covid-19 vaccine to curb the global pandemic and return life to normal.While one or more options could be available toward the end of this year or early next, the path to delivering vaccines to a population of 330 million people remains...

"Hotspots" of a corona infection in the human body

An infection with the coronavirus SARS-CoV-2 can affect multiple organs. With this in mind, researchers of the German Center for Neurodegenerative Diseases (DZNE) and Cornell University in the US have investigated cellular factors that could be significant for an infection. To this end, they analysed the activity of 28 specific genes in a wide range of human tissues. Their findings, which provide...

'Attack Helicopters' an online sub-culture to watch out for

Who identifies sexually as an 'attack helicopter?" According to new QUT-led research some 'Incels' do, and while 'trolls' have been around almost as long as the Internet, the researchers say 'Incels' are a more recent and distinctly different cyber sub-culture which warrants more study. Their findings have just been published by open access journal First Monday.

'Social smokers' face disproportionate risk of death from lung disease and lung cancer

'Social smokers' are more than twice as likely to die of lung disease and more than eight times as likely to die of lung cancer than non-smokers, according to research presented at the European Respiratory Society International Congress. The study also shows that the risk of lung cancer death for 'social smokers' - those who smoke less than ten cigarettes per day - is not substantially lower than...

A 400-year-old chamois will serve as a model for research on ice mummies

The chamois had been protected by the glacier for 400 years and only recently released due to the ice having receded. Due to their age and state of preservation, the remains are in fact a perfect simulant of a human mummy and will allow researchers to improve the conservation techniques of ice mummies all over the world while determining methods for the safeguarding of ancient DNA - a mine of...

A new model to predict survival in colorectal cancer

This signature could be useful in clinical practice, especially for colorectal cancer diagnosis and therapy. Future studies should determine the effectiveness of integration in cancer survival analysis and the application on unbalanced data, where the classes are of different sizes, as well as on data with multiple classes.

A spicy silver lining

Researchers David Omar Oseguera-Galindo and Eden Oceguera-Contreras, both of the University of Guadalajara, Mexico, and Dario Pozas-Zepeda of the University of Colima, Mexico, recently studied the effect of habanero pepper in the synthesis of silver nanoparticles. Their research, published in the Journal of Nanophotonics, resulted in a simple, low-cost, ecofriendly method of obtaining silver...

Attacking tumors from the inside

A new technology that allows researchers to peer inside malignant tumors shows that two experimental drugs can normalize aberrant blood vessels, oxygenation, and other aspects of the tumor microenvironment in non-small cell lung cancer (NSCLC), helping to suppress the tumor's growth and spread, UT Southwestern researchers report.

Autonomous robot plays with NanoLEGO

Atoms and molecules behave in a completely different way to macroscopic objects and each brick requires its own "instruction manual". Scientists from Jülich and Berlin have now developed an artificial intelligence system that autonomously learns how to grip and move individual molecules using a scanning tunnelling microscope.

Better customer care on Twitter leads to nearly 20% increase in customer satisfaction

Social media has forever changed our society and how people do business. A 2013 report by J.D. Power found nearly two-thirds of customers have used a company's social media site to connect with customer service. New research in the INFORMS journal Information Systems Research finds businesses that use Twitter as a social care channel are seeing a 19% increase in customer satisfaction.

Bronchitis as a child predicts worse lung health in middle age

People who had bronchitis at least once before the age of seven are more likely to develop lung problems in later life, according to new research presented at the 'virtual' European Respiratory Society International Congress. However, the lung diseases they suffer from by the age of 53 were usually asthma and pneumonia rather than chronic bronchitis.

Cell division: Cleaning the nucleus without detergents

A team of researchers, spearheaded by the Gerlich lab at IMBA, has uncovered how cells remove unwanted components from the nucleus following mitosis. The results, published in the journal Nature, stem from a fruitful collaboration between the Gerlich lab and former IMBA Postdoc Sara Cuylen-Häring, who recently established her own group at EMBL.

Children can have COVID-19 antibodies and virus in their system simultaneously

With many questions remaining around how children spread COVID-19, Children's National Hospital researchers set out to improve the understanding of how long it takes pediatric patients with the virus to clear it from their systems, and at what point they start to make antibodies that work against the coronavirus. The study, published Sept. 3 in the Journal of Pediatrics, finds that the virus and...
