Syphilis is a sexually transmitted disease - and while commonly dismissed due to the availability of modern treatments, it is in fact spreading at an alarming rate: Over the last decades, more than 10 million people around the world have been infected with the syphilis subspecies pallidum of the Treponema pallidum bacteria. Other treponematoses, such as yaws and bejel, are caused by other subspecies of Treponema pallidum. The origins of syphilis, which wreaked havoc in Europe from the late 15th to the 18th century, are still unclear.
Researchers have shed fresh light on the evolution and function of the shapes we see in nature - using as a model the heart shaped fruits of the Capsella genus.
The natural world is full of diverse shapes from organs to whole organisms that are fitted by evolution to perform and reproduce optimally in their environment.
The Capsella seed pods with their distinctive heart-shaped shoulders offer an anatomical novelty and an excellent study system for understanding the diversity of shapes.
Social inequalities, specifically racism and classism, are impacting the biodiversity, evolutionary shifts and ecological health of plants and animals in our cities.
University of Otago researchers have learnt more about how viruses operate and can evade the immune system and are now using their discovery to help learn more about COVID-19.
New research by Dr Camilla Whittington and her team at the University of Sydney has found male seahorses transport nutrients to their developing babies during pregnancy. This discovery provides an opportunity for further comparative evolutionary research.
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed an Artificial Intelligence (AI) system that recognises hand gestures by combining skin-like electronics with computer vision.
The recognition of human hand gestures by AI systems has been a valuable development over the last decade and has been adopted in high-precision surgical robots, health monitoring equipment and in gaming systems.

Using state-of-the-art 3D microscopy and mathematics, Dr Hermes Gadêlha from the University of Bristol, Dr Gabriel Corkidi and Dr Alberto Darszon from the Universidad Nacional Autonoma de Mexico, have reconstructed the movement of the sperm tail in 3D with high-precision.
John Steinbeck wrote Log From the Sea of Cortez in 1951, his chronicle of an expedition with marine biologist Ed Ricketts along the coast of California and Mexico. Ricketts named several of the many new marine animals they found after Steinbeck, his friend and patron of the expedition. On a similar expedition in February 2019 to Panama's Coiba National Park in the Pacific Ocean, marine biologists from the Smithsonian Tropical Research Institute (STRI) discovered several new, undescribed animals, genera and species never seen or photographed before, nearly every day.
A study from Emory Vaccine Center provides insights into why the boost in immunity from seasonal flu vaccination lasts for months but not years, unlike some childhood vaccinations.
The home base for immune cells that produce antibodies is the bone marrow. Seasonal flu vaccination does increase the number of antibody-producing cells specific for flu in the bone marrow. However, most of the newly generated cells are lost within one year, Emory researchers found.
Employers in Sweden more often reject job applications from transgender people - especially in male-dominated occupations. Moreover, transgender people face discrimination from two different grounds for discrimination. This is according to a study from Linköping University that was recently published in the journal Labour Economics.
In many studies, bariatric surgery has been highlighted as an almost magical method for weight loss and reversing type 2 diabetes. One question that has remained largely unanswered is how the effect of surgery differs from the effects of a strict low-calorie diet. This question has now been examined by researchers at Lund University in Sweden in a study published in the journal Diabetes.
By monitoring individuals who underwent a six-week low-calorie diet followed by a bariatric operation, they can for the first time show why several health markers improve.
The rainforests of Southeast Asia are among the fastest declining tropical ecosystems worldwide. Researchers from 13 institutions studied an area of tropical forest in Sabah, Malaysian Borneo that had suffered heavy logging in the 1980s but was subsequently protected from further deforestation or conversion to agricultural land.
Scientists sound the alarm: Lockdowns may escalate the obesity epidemic
Emotional stress, economic anxiety, physical inactivity and social distance - locking down society to combat COVID-19 creates psychosocial insecurity that leads to obesity, warn three Danish researchers. Counter measures are needed if we are to keep the public both metabolically healthy and safe from the coronavirus
