Scientists said Monday they have developed the first mobile printer that can produce thumbnail-sized patches able to deliver mRNA Covid vaccines, hoping the tabletop device will help immunise people in remote regions.While many hurdles remain and the 3D printer is likely years away from becoming available, experts hailed the "exciting" finding.The device prints two-centimetre-wide patches which each contain hundreds of tiny needles that administer a vaccine when pressed against the skin.These "microneedle patches" offer a…

<!----> Nissan says it is highlighting a range of electrified and seamlessly connected vehicles at Auto Shanghai 2023. Premieres include two EV concepts: the Max-Out convertible sports car, which made its China debut, and the Arizon SUV, which made its global debut. The locally developed…

Salmonella bacteria are responsible for the most common type of food poisoning, which can cause people to become quite ill. A new test, however, is able to detect the microbes' presence in food faster and easier than ever before.One of the problems with salmonella-tainted foods – most often meats, fruits and vegetables – is the fact that they typically don't look, smell or taste any different than they usually do. And while it already is possible to test food samples for the bacteria, those tests involve growing bacterial…

Researchers at Indiana University School of Medicine have developed a blood test for anxiety by examining biomarkers, which can determine a patient’s risk, severity, and the most effective treatment options. The test, currently being developed for wider use by MindX Sciences, can help provide a comprehensive report for patients and physicians using a single blood sample, potentially aiding in early diagnosis and targeted treatment.Scientists at the Indiana University School of Medicine have successfully created a blood…

A team of researchers at the Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) has created a totally edible and rechargeable battery, starting from materials that are normally consumed as part of our daily diet. The proof-of-concept battery cell has been described in a paper published in the Advanced Materials journal. The possible applications are in health diagnostics, food quality monitoring, and edible soft robotics. Credit: IIT-Istituto Italiano di TecnologiaThe world’s first rechargeable edible…

For the first time, a team of mathematicians has developed a model that can map the best way for those with penises to reach sexual climax.After combing through decades of data on both physiological and psychological arousal, the researchers say they've found the ideal conditions required to achieve orgasm."We have developed the first successful mathematical model of sexual performance," says mathematician Konstantin Blyuss, one of the lead researchers from the University of Sussex in the UK."Our results cover the…

Credit: Zhang RuofanA team of researchers under the leadership of Prof. Meng Gang from the Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), explored the use of polydimethylsiloxane (PDMS) in developing high-performance, humidity-resistant hydrogen sulfide (H2S) sensors, providing a path towards the…

The knotted materials, which were created out of polymers, exhibit a tensile toughness that far surpasses materials that are unknotted but otherwise structurally identical, including ones where individual strands are interwoven instead of knotted. Credit: CaltechCaltech engineers have made a significant breakthrough in the field of nano- and micro-architected materials by creating a novel material composed of multiple interconnected microscale knots.Compared to structurally identical but unknotted materials, the presence…
