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

Research reveals how brain inflammation triggers extreme muscle weakness across several diseases, including viral infection, bacterial infection and Alzheimer's disease. The study, in fruit flies and mice, also identified ways to block this process, which could have implications for treating or preventing the muscle wasting sometimes associated with inflammatory diseases, including bacterial infections, Alzheimer's disease
A new study suggests that people who are trying to conceive and live close to oil and gas development sites have a heightened risk of developing adverse mental health outcomes. The study found that people who lived within roughly six miles of active oil and gas development had greater development of moderate-to-severe depressive symptoms, compared
Artificial intelligence (AI) chatbots have frequently shown signs of an 'empathy gap' that puts young users at risk of distress or harm, raising the urgent need for 'child-safe AI', according to a new study. The research urges developers and policy actors to prioritize AI design that take greater account of children's needs. It provides evidence
Researchers have developed a groundbreaking method for analysing heart MRI scans with the help of artificial intelligence, which could save valuable time and resources, as well as improve care for patients.

Researchers have identified how a common bacterium is able to manipulate the human immune system during respiratory infections and cause persistent illness. Researchers from The University of Queensland have identified how a common bacterium is able to manipulate the human immune system during respiratory infections and cause persistent illness. The research, led by Professor Ulrike
Board gaming is a growing industry, and anecdotally popular among people who display autistic traits. Now new research has highlighted the science supporting the anecdote -- and the important reasons behind the link.

In a new study, researchers used low-intensity ultrasound technology to noninvasively alter a brain region associated with activities such as daydreaming, recalling memories and envisioning the future. One of the intriguing abilities of the human mind is daydreaming, where the mind wanders off into spontaneous thoughts, fantasies and scenarios, often without conscious effort, allowing creativity
The human brain is remarkably adept at adjusting what we hear based on contexts, like our current environment or priorities, but it's still unknown how exactly the brain helps us detect, filter and react to sounds. Now, biologists are a step closer to solving that mystery. Using an animal model, the researchers found that the
How do people like to interact with robots when navigating a crowded environment? And what algorithms should roboticists use to program robots to interact with humans? These are the questions that a team of mechanical engineers and computer scientists sought to answer in a recent study. How do people like to interact with robots when
Even years after they have recovered, a person who once struggled with alcohol or opioid addiction can relapse--and that relapse is more likely to occur during particularly stressful times. Now, scientists have identified an area of the brain that plays a key role in stress-induced oxycodone relapse. Their findings explain why the drug suvorexant, which
A multi-institutional study found that 1 in 6 youths fill an opioid prescription prior to surgery, and 3% of patients were still filling opioid prescriptions three to six months after surgery, indicating persistent opioid use and possible opioid dependence. The study underscores that more guidance is needed to steer clinicians away from prescribing opioids when
In chronic hepatitis B, the liver contains immune cells that could destroy hepatitis B virus infected cells but are inactive. Researchers have discovered that cells blood vessels in the liver start a 'sleep timer' that switches off immune cells. Targeting this mechanism could be a starting point for immunotherapies. In chronic hepatitis B, the liver
