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
Geosmin is a volatile compound of microbial origin with a distinct 'earthy' to 'musty' odor that can affect the quality of water and food. A research team has now identified and characterized the human odorant receptor for geosmin for the first time. Geosmin is a volatile compound of microbial origin with a distinct "earthy" to

Food in hospitals often does not enjoy a good reputation. The proportion of meat on the plate in particular is too high. Clinics can do a lot to motivate patients to choose a healthier menu, as two new studies show. Food in hospitals often does not enjoy a good reputation. The proportion of meat on

Researchers have found that intense stress can be felt at the cellular level and is linked to negative physical and mental health effects. It's no secret that the caregivers of spouses with memory impairment face enormous amounts of stress. Researchers at Rice University have found that this intense pressure can be felt at the cellular
Adolescents consume around two-thirds of their daily calories from ultra-processed foods (UPFs) new research has found. The study found that UPF consumption was highest among adolescents from deprived backgrounds, those of white ethnicity, and younger adolescents. Adolescents consume around two-thirds of their daily calories from ultra-processed foods (UPFs) new research from the Universities of Cambridge
Investment in research into genetics could dramatically improve educational policies and understanding of parenting in ways that could help all children, according to a new paper.

Researchers propose an improvement in the identification of human remains using craniofacial superimposition. The forensic identification technique is based on the analysis of a skull (post-mortem) and photographs of the person's face (ante-mortem). It represents a major step in making objective decisions that are based on the ability to quantify the probability that a skull
Researchers studying antimicrobial-resistant E. coli -- the leading cause of human death due to antimicrobial resistance worldwide -- have identified a mechanism in dogs that may render multiple antibiotic classes ineffective.

Researchers have identified a new way to make opioids safer, increasing the pain-relieving properties of opioids while decreasing unwanted side effects through the spinal inhibition of a Heat shock protein 90 isoform. Researchers at the University of Arizona Health Sciences identified a new way to make opioids safer, increasing the pain-relieving properties of opioids while
Rigorous exercise before bed has long been discouraged, but researchers have now found short bursts of light activity can lead to better sleep.

Industrialized farming is often thought to reduce the risk of zoonotic diseases because of better control, biosecurity and separation of livestock. A new study examines the effect of social and economic factors -- which are often overlooked in traditional assessments. Intensive livestock farming could raise the risk of new pandemics, researchers have warned. Industrialised farming
A new report highlights a troubling trend: while global adolescent fertility rates have significantly declined, sub-Saharan Africa is experiencing an increase in teen births. This region's share of global adolescent births surged from 12 percent in 1950 to 47 percent in 2020 and is projected to reach a clear majority -- a full 67 percent
Researchers examined the clinical, lifestyle, and multi-omic data of more than 1,400 healthy adults. How often people poop, they found, can have a large influence on one's physiology and health. Everybody poops, but not every day. New research by the Institute for Systems Biology (ISB) suggests bowel movement frequency is linked to long-term health. An
Delivery systems in body continuously move materials between cells. Hijacking these systems allowed scientists to improve loading and delivery of therapeutic proteins. Biophysical principles could be used to enable more cost-effective loading of biological cargo into cell-derived delivery systems. Engineered molecules loaded up to 240 times more protein than other loading methods. Each cell in
Researchers have developed a strategy to identify new antimicrobial drugs with therapeutic promise from bacterial datasets, providing clues for discovering alternatives to traditional antibiotics.
