Over the past decades, researchers have developed a wide range of advanced social and assistance robots that could soon be introduced into households worldwide. Understanding how the introduction of these systems might impact the lives of users and their interactions with others living in their homes is crucial, as it could inform the further improvement of robots before their widespread deployment.

Recent studies suggest that household robot companions could foster educational conversations between parents and children, particularly during story-reading sessions. By actively participating in these sessions, for instance by asking questions or assuming the role of a playmate, robots were found to augment interactions between children and their caregivers, enriching their conversations and supporting the children’s acquisition of new vocabulary.

Researchers at the Massachusetts Institute of Technology (MIT) recently carried out a study to further explore the potential of social robots as catalysts and tools to enhance interactions between children and parents. Their findings, published in Science Robotics, suggest that English-speaking robots can improve the quality of dialogue between parents and children, with families that fluently speak English benefitting more from their use.

The use of virtual reality haptic simulators can enhance skill acquisition and reduce stress among dental students during preclinical endodontic training, according to a new study published in the International Endodontic Journal. The study was based on collaboration between the University of Eastern Finland, the University of Health Sciences and the University of Ondokuz Mayıs in Turkey as well as Grande Rio University in Brazil.

The study aimed to evaluate the influence of virtual reality (VR) haptic simulators on skill acquisition and stress reduction in endodontic preclinical education of dental students.

During preclinical training, dental students develop manual dexterity, psychomotor skills and confidence essential in clinical practice. VR and haptic technology are increasingly used alongside conventional methods, enabling more repetition and standardised feedback, among other things.

A new approach to streaming technology may significantly improve how users experience virtual reality and augmented reality environments, according to a study from NYU Tandon School of Engineering.

The research—presented in a paper at the 16th ACM Multimedia Systems Conference (ACM MMSys 2025) on April 1, 2025—describes a method for directly predicting visible content in immersive 3D environments, potentially reducing bandwidth requirements by up to 7-fold while maintaining visual quality.

The technology is being applied in an ongoing NYU Tandon project to bring point cloud video to dance education, making 3D dance instruction streamable on standard devices with lower bandwidth requirements.

Niels Henrik David Bohr was born in Copenhagen on October 7, 1885, as the son of Christian Bohr, Professor of Physiology at Copenhagen University, and his wife Ellen, née Adler. Niels, together with his younger brother Harald (the future Professor in Mathematics), grew up in an atmosphere most favourable to the development of his genius – his father was an eminent physiologist and was largely responsible for awakening his interest in physics while still at school, his mother came from a family distinguished in the field of education.

After matriculation at the Gammelholm Grammar School in 1903, he entered Copenhagen University where he came under the guidance of Professor C. Christiansen, a profoundly original and highly endowed physicist, and took his Master’s degree in Physics in 1909 and his Doctor’s degree in 1911.

While still a student, the announcement by the Academy of Sciences in Copenhagen of a prize to be awarded for the solution of a certain scientific problem, caused him to take up an experimental and theoretical investigation of the surface tension by means of oscillating fluid jets. This work, which he carried out in his father’s laboratory and for which he received the prize offered (a gold medal), was published in the Transactions of the Royal Society, 1908.

Heaviside was born in Camden Town, London, at 55 Kings Street [ 3 ] : 13 (now Plender Street), the youngest of three children of Thomas, a draughtsman and wood engraver, and Rachel Elizabeth (née West). He was a short and red-headed child, and suffered from scarlet fever when young, which left him with a hearing impairment. A small legacy enabled the family to move to a better part of Camden when he was thirteen and he was sent to Camden House Grammar School. He was a good student, placing fifth out of five hundred students in 1865, but his parents could not keep him at school after he was 16, so he continued studying for a year by himself and had no further formal education. [ 4 ] : 51

Heaviside’s uncle by marriage was Sir Charles Wheatstone (1802–1875), an internationally celebrated expert in telegraphy and electromagnetism, and the original co-inventor of the first commercially successful telegraph in the mid-1830s. Wheatstone took a strong interest in his nephew’s education [ 5 ] and in 1867 sent him north to work with his older brother Arthur Wheatstone, who was managing one of Charles’ telegraph companies in Newcastle-upon-Tyne. [ 4 ] : 53

Two years later he took a job as a telegraph operator with the Danish Great Northern Telegraph Company laying a cable from Newcastle to Denmark using British contractors. He soon became an electrician. Heaviside continued to study while working, and by the age of 22 he published an article in the prestigious Philosophical Magazine on ‘The Best Arrangement of Wheatstone’s Bridge for measuring a Given Resistance with a Given Galvanometer and Battery’ [ 6 ] which received positive comments from physicists who had unsuccessfully tried to solve this algebraic problem, including Sir William Thomson, to whom he gave a copy of the paper, and James Clerk Maxwell. When he published an article on the duplex method of using a telegraph cable, [ 7 ] he poked fun at R. S. Culley, the engineer in chief of the Post Office telegraph system, who had been dismissing duplex as impractical.

I very much enjoyed reading this nicely done preclinical study on using nebulized vasopressin to improve social cognition in low-sociality rhesus monkeys. Reading about their study design in particular was highly informative/educational! #preclinical #medicine #biomedicine

Low cerebrospinal (CSF) arginine vasopressin (AVP) concentration is a biomarker of social impairment in low-social monkeys and children with autism, suggesting that AVP administration may improve primate social functioning. However, AVP administration also increases aggression, at least in “neurotypical” animals with intact AVP signaling. Here, we tested the effects of a voluntary drug administration method in low-social male rhesus monkeys with high autistic-like trait burden. Monkeys received nebulized AVP or placebo, using a within-subjects design. Study 1 (N = 8) investigated the effects of AVP administration on social cognition in two tests comparing responses to social versus nonsocial stimuli. Test 1: Placebo-administered monkeys lacked face recognition memory, whereas face recognition memory was “rescued” following AVP administration.

Without eclipses, our world would be a lot different because eclipses give us the ability to do science we otherwise wouldn’t be able to.
