Aleksei Smirnov, Assistant Professor, HSE University Faculty of Economic Sciences, and Egor Starkov, Assistant Professor, University of Copenhagen, have constructed a mathematical model that explains why it is advantageous for sellers not to delete negative reviews of their products. A study detailing this conclusion has been accepted for publication in The American Economic Journal: Microeconomics.
UCLA RESEARCH BRIEF
FINDINGS
UCLA researchers have identified a potential diagnostic marker that could help predict how likely someone with cervical cancer is to respond to the standard treatment of chemotherapy and radiation.
CHICAGO (December 11, 2020): Financial toxicity among breast cancer patients is independently associated with worse psychological well-being following a mastectomy or lumpectomy operation.
Researchers from The University of Texas at Arlington resurrected the preserved eggs of a shrimp-like crustacean to examine long-standing questions about adaptive evolution, reporting the results in the journal Proceedings of the National Academy of Science.
WHAT:
The combination of baricitinib, an anti-inflammatory drug, and remdesivir, an antiviral, reduced time to recovery for people hospitalized with COVID-19, according to clinical trial results published in the New England Journal of Medicine. The study was supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
URBANA, Ill. - Smallholder farmers in Sub-Saharan Africa use fertilizer well below recommended rates, contributing to consistently low agricultural productivity. Farmers in Tanzania and Kenya, for example, apply just 13 kilograms of fertilizer per hectare, compared with 165 to 175 kilograms in India and Brazil. Low use directly affects cereal yields, which average 1.2 to 1.7 metric tons per hectare, compared to 4 to 4.5 metric tons in South America and Asia.
CHAPEL HILL, NC - It's been shown that when two people wearing masks interact, the chance of COVID-19 transmission is drastically reduced. This is why public health officials have pleaded for all people to wear masks: they not only protect the wearer from expelling particles that might carry SARS-CoV-2, the virus that causes coronavirus 2019 (COVID-19), but masks also protect the wearer from inhaling particles that carry the virus. Some people, though, still refuse to wear a mask.
Offering an ultrasensitive yet accessible approach to COVID-19 testing, a portable saliva-based smartphone platform provides results within 15 minutes without the resource-intensive laboratory tests the current gold standard requires, according to a new study. The approach was tested in 12 people infected with COVID-19 and 6 healthy controls.
Political partisanship has had outsized influence on individual social mobility during COVID-19 pand
In the United States, political partisanship has played a much stronger role in individuals' decisions to limit their social mobility during the COVID-19 pandemic than the local incidence of the disease in their own communities, according to a new survey-based study of 1,135,638 million responses collected between April 4 and September 10, 2020 via Survey Monkey from randomly chosen people.
BOSTON - "Wet" age-related macular degeneration (AMD) is one of the most common causes of irreversible vision loss in the elderly, and it occurs when abnormal and leaky blood vessels form in the retina, in part due to inflammation. New research by investigators at Massachusetts General Hospital (MGH) reveals insights into potential drivers of the disease -- which currently has no cure -- that could be targeted through prevention or treatment strategies. The findings are published in eLife.
People in European countries with the strictest COVID-19 lockdown policies were more likely to show symptoms of depression and anxiety, according to an international study investigating the impact of disconnecting from nature.
Over the past 20 years, the number of passengers traveling on British train networks has almost doubled to 1.7 billion annually. With numbers like that it's clear how much people rely on rail service in Great Britain, and how many disgruntled patrons there would be when delays occur. A recent study used real British Railway data and an artificial intelligence model to improve the ability to predict delays in railway networks.

Rancho Santa Margarita, Calif. (Dec. 10, 2020) --- An in vitro study published in the Journal of Dietary Supplements, demonstrated Blue California's ErgoActive® ergothioneine helped to preserve telomere length and reduced the rate of telomere shortening under oxidative stress.
In a paper published in NANO, researchers from Nanjing Tech University proposed a theory which attributes the photocatalytic efficiency enhancement of Phosphorus and Nitrogen co-doped CQDs (PNCQDs)/TiO2 nanosheets composite photocatalyst to the quantum wells of PNCQDs.
