The new test revealed that first outbreak isolates were falsely clustered by classical genotyping, providing valuable insights into the evolution of M. tuberculosis.
A study finds diclofenac is the most commonly used NSAID in 15 countries and is included on essential medicines lists of 74 low- to high-income countries. Despite its cardiovascular risks, researchers call for diclofenac to be removed from national lists and have its global marketing authorisations revoked.
A study published in PLOS Pathogens found that HIV exploits a human cytokine called interleukin 7 (IL-7) in semen to promote its own transmission. The researchers discovered that the increased concentration of IL-7 in semen facilitates HIV transmission to cervical tissue ex vivo.
A 397,000-year-old fossil found in Serbia reveals that southeastern European human ancestors evolved differently than those in western Europe due to the absence of glaciers. The study confirms southeast Europe as a critical 'gate to the continent' where humans, plants, and animals sought refuge during glaciations.
Research published in PLOS ONE found that older adults spend less time fixating text and show lower brain activity when using e-readers compared to paper books. This is likely due to better text discrimination on backlit displays, benefiting older readers. No issues with comprehension were reported.
A recent study published in PLOS ONE found that women who are more aware of their internal bodily signals, such as their heartbeat, tend to have lower levels of self-objectification. This increased awareness is linked to a reduced tendency to think of one's body as an object, rather than a source of physical competence and health.
The African Programme for Onchocerciasis Control has had a major health impact, reducing blindness and itching cases by millions, while costing only $250 million. The program saved an estimated 8 million healthy years of life, at a cost of just $30 per year.

This breakthrough oncolytic herpesvirus has shown promising results in treating experimental metastasis, holding promise for a novel type of cancer treatment.
Research published in PLOS ONE shows that chimps can learn more efficient ways to use a tool by watching others. In an experiment, chimps were given juice-boxes with small holes and straws to drink with, and those that watched peers demonstrate the more efficient 'straw-sucking' technique switched to using it.
The star-nosed mole's star-shaped snout contains a high proportion of nerve endings sensitive to light touch, with fewer receptors that detect pain. This study highlights the importance of examining diverse species to reveal common biological mechanisms.
Adding a new member to a working group can create distrust among older members, leading to decreased coordination. When previous group performance with just the older group members is poor, the distrust created is exacerbated.

Researchers found that N. meningitidis adhesion to human microvessels leads to endothelial inflammatory response, clotting, thrombosis, congestion, and vascular leak, resulting in purpuric rash development. The study's findings challenge previous assumptions about the role of circulating bacteria and LPS release in vascular damage.
Research finds widening gap in obesity estimates attributed to biased self-reports of weight. Increasing bias in self-reported weight contributes to underestimation of clinically measured BMIs.

Researchers found that during a nematode-induced inflammation, the immune system increases cholecystokinin levels, reducing leptin production, which drives defense mechanisms against the parasite. The study suggests a novel mechanism for parasite expulsion in intestinal infections.
African sleeping sickness, caused by a brain-invading parasite transmitted by tsetse flies, can persist in areas with no human cases due to wild animal populations. A new study suggests that targeting humans alone may not be enough to control the disease and that efforts must factor in wild animals.
