Highly localized TB strains are less infectious in cosmopolitan cities and more likely to infect people from the geographic area that is the strain's natural habitat. The research provides the first controlled evidence that TB strains may evolve with their human hosts, adapting to be more infectious to specific populations. The findings offer new clues
A new small study has revealed the impact of obesity on muscle structure in patients having a form of heart failure called heart failure with a preserved ejection fraction (HFpEF). A new small study led by Johns Hopkins Medicine researchers and published July 25th in the journal Nature Cardiovascular Research has revealed the impact of

Strokes lead to irreversible damage to the brain and are one of the most common causes of dependency or death. As the cellular reactions to a cerebral infarction are not yet fully understood, there is a lack of possible approaches to promote the regeneration of damaged nerve tissue in the brain. A new study closes

A new study sheds light on factors that may have predisposed some patients to recover more slowly after COVID. Early in the pandemic, many people who had SARS-Cov-2 infection or COVID-19 began to report that they couldn't shake off their symptoms even after a month or more -- unusually long for a viral infection of
During the COVID-19 pandemic, at-home antigen tests became widely accepted for detecting infection. In a new study, researchers looked into the benefits of using at-home antibody tests to detect immunity and to make decisions about the need for a COVID-19 booster shot -- something that may be of particularly relevance for those at high risk
Recently, scientists found that some people who suffered from COVID-19 had auto-antibodies targeting their own type 1 interferons, which are important immune signaling proteins. Now, researchers conducted an in-depth study on 123 Japanese COVID-19 patients to clarify just how common these auto-antibodies are among severe cases and how they affect the immune system. Their findings
A new study shows that people with COVID-19 who used cannabis were more likely to be hospitalized and require intensive care than those who did not use the drug. As the deadly disease that came to be known as COVID-19 started spreading in late 2019, scientists rushed to answer a critical question: Who is most
Researchers have created a questionnaire test for home use that quickly identifies high risk of heart attack. A study shows that it has the same level of accuracy as blood tests and blood pressure measurements. Swedish researchers have created a questionnaire test for home use that quickly identifies high risk of heart attack. A study
Scientists show that specifying the timing pattern of neurostimulation -- impulses used to activate the brain's own electrical signaling mechanisms -- can rebalance the strength of synaptic connections between nerve cells, selectively up- or down-regulating those connections. An awkward beat doesn't help on the dance floor, but it could help people who are recovering from
A new study provides insight on how to make a new generation of rapid tests, including COVID, flu, RSV, and all-in-one tests, work better. Peek in medicine cabinets across the U.S. and you'll find stacks of leftover COVID-19 tests. When symptoms arise, so do questions: When should I test? How accurate is it really? And
Reducing consumption of processed meat by around one-third could prevent more than 350,000 cases of diabetes in the US over 10 years. Reducing consumption of processed meat by around one-third could prevent more than 350,000 cases of diabetes in the US over 10 years, a study suggests. Cutting US adults' processed meat intake by 30
Researchers have discovered several rare types of helper T cells that are associated with immune disorders such as multiple sclerosis, rheumatoid arthritis, and even asthma. The discoveries were made possible by a newly developed technology they call ReapTEC. The new T cell atlas is publicly available and should help in the development of new drug
Pseudomonas aeruginosa -- an environmental bacteria that can cause devastating multidrug-resistant infections, particularly in people with underlying lung conditions -- evolved rapidly and then spread globally over the last 200 years, probably driven by changes in human behavior, a new study has found. Pseudomonas aeruginosa -- an environmental bacteria that can cause devastating multidrug-resistant infections
New findings challenge the idea that academically selective schools are necessary for clever pupils to achieve good outcomes. Findings published in a new peer-reviewed paper in the British Journal of Educational Studies challenges the idea that academically selective schools are necessary for clever pupils to achieve good outcomes. Selective schools are government-funded schools that enrol
Young adults who have higher levels of inflammation, which is associated with obesity, physical inactivity, chronic illness, stress and smoking, may experience reduced cognitive function in midlife, a new study has found. Higher inflammation in young adulthood linked to lower performance in skills testing in midlife. Young adults who have higher levels of inflammation, which
