Astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter’s moon Ganymede. This water vapor forms when ice from the moon’s surface sublimates — that is, turns from solid to gas. Astronomers re-examined Hubble observations from the last two decades to find this evidence of water vapor. Scientists used new and archival datasets…

A new study finds male black widow spiders will hijack silk trails left by rival males in their search for a potential mate. Male black widows will follow chemical cues (pheromones) released by potential female mates, but it was always assumed they would avoid rival males because competition is so fierce. «We expect males to…

Additive free, multimaterial 3D printing is achieved for milk-based products without temperature control. 3D printing of food has been achieved by different printing methods, including the widely used selective laser sintering (SLS) and hot-melt extrusion methods. However, these methods are not always compatible with temperature-sensitive nutrients found in certain types of food. For instance, milk…

New research demonstrates the ability of dogs to detect aggressive prostate cancer from urine samples and suggests that an artificial neural network could learn from this olfactory ability, with an eye toward replicating it in novel detection tools. The widely used prostate specific antigen (PSA) screening test can miss aggressive prostate cancer in men who…

A new study shows that part of the stress response in people and animals involves increasing the levels of naturally circulating iodide in blood. The discovery demonstrates a biological mechanism that rapidly responds to severe physiologic stress and potentially serves to protect us from further damage due to life-threatening conditions. The discovery demonstrates a biological…

Treating obese mice with the cytokine known as TSLP led to significant abdominal fat and weight loss compared to controls. The animal model findings support the possibility that increasing sebum production via the immune system could be a strategy for treating obesity in people. «This was a completely unforeseen finding, but we’ve demonstrated that fat…

Researchers demonstrate a robust experimental technique for studying one particular theory for dark energy. Named ‘Gravity Resonance Spectroscopy,’ their approach could bring researchers a step closer to understanding one of the greatest mysteries in cosmology. Previously, phenomena named ‘scalar symmetron fields’ have been proposed as a potential candidate for Dark Energy. If they exist, these…

Life is deeply dependent on water, but where does water come from? Based on new research, researchers believe it may emerge in connection with the formation of planets. So far, so good. But if life emerged in water, where did the water come from? «There are two hypotheses about the emergence of water. One is…

An international research team has developed ‘electronic skin’ sensors capable of mimicking the dynamic process of human motion. This work could help severely injured people, such as soldiers, regain the ability to control their movements, as well as contribute to the development of smart robotics, according to researchers. Cheng and collaborating researchers based in China…

If humanoid robots with the same appearance are mass-produced and become commonplace, how will human beings react to them? In a series of six experiments, scientists examined peoples’ reactions when presented with images of people with the same face. Their results reveal a new phenomenon they call the clone devaluation effect — a greater eeriness…
