Association Between Osteoporosis and Adiposity Index Reveals Nonlinearity Among Postmenopausal Women and Linearity Among Men Aged over 50 Years

Association Between Osteoporosis and Adiposity Index Reveals Nonlinearity Among Postmenopausal Women and Linearity Among Men Aged over 50 Years

Po‐Ju Chen, Yueh‐Chien Lu, Sheng‐Nan Lu, Fu‐Wen Liang, Hung‐Yi Chuang

Could carrying more body fat sometimes protect bones, but only up to a point, and differently for women and men? This study finds that the answer is not a simple “more” or “less.”

Matching the pitch perception of the cochlear implanted ear with the contralateral ear in patients with single-sided deafness: a novel approach

Matching the pitch perception of the cochlear implanted ear with the contralateral ear in patients with single-sided deafness: a novel approach

Tamás Tóth, Á. Németh, Péter Bakó, Péter Révész, Imre Gerlinger, István Szanyi

A cochlear implant can restore access to sound, yet speech may still feel strangely out of tune between the two ears. This study asks whether retuning that mismatch can make noisy conversations easier.

Clinical trajectory of intraductal papillary mucinous neoplasms progressing to pancreatic carcinomas during long-term surveillance: a prospective series of 100 carcinoma cases

Clinical trajectory of intraductal papillary mucinous neoplasms progressing to pancreatic carcinomas during long-term surveillance: a prospective series of 100 carcinoma cases

Hiroki Oyama, Tsuyoshi Hamada, Yousuke Nakai, Mariko Tanaka, Go Endo, Ryunosuke Hakuta, Kota Ishida, Kazunaga Ishigaki, Sachiko Kanai, Kohei Kurihara, Tomotaka Saito, Tatsuya Sato, Tatsunori Suzuki, Yukari Suzuki, Shinya Takaoka, Shuichi Tange, Yurie Tokito, Naminatsu Takahara, Tetsuo Ushiku, Mitsuhiro Fujishiro

Regular scans can watch a pancreatic cyst for years, yet a dangerous cancer may still appear without the warning signs doctors expect. This study reveals why surveillance is harder than it looks.

Machine Learning Based Fault Classification in Pilot Plant Batch Reactor: Using Support Vector Machine

Machine Learning Based Fault Classification in Pilot Plant Batch Reactor: Using Support Vector Machine

Arockiaraj Simiyon, Chaitanya Sachidanand, Manthana Halmakki Krishnamurthy, Ananya V. Bhatt, I Thirunavukkarasu

A chemical reactor can drift toward poor quality or danger through changes that are hard to see in time. This study found that a computer could sort several kinds of reactor trouble with remarkable accuracy, but the real plant test still lies ahead.

Primary and middle-school children’s drawings of the lockdown in Italy

Primary and middle-school children’s drawings of the lockdown in Italy

Michele Capurso, Livia Buratta, Claudia Mazzeschi

When children were asked to draw their lockdown lives, many did not draw the outside world at all. And among older children, the child in the picture was often missing, or had no face.

Single-molecule visualization of mRNA circularization during translation

Single-molecule visualization of mRNA circularization during translation

Byungju Kim, Jincheol Seol, Yoon Ki Kim, Jong‐Bong Lee

Inside every living cell, tiny messages are read to build proteins. Scientists thought many of those messages formed helpful loops, but watching them one at a time suggests the loop may be an illusion of motion.

Identification of the molecular subgroups in Alzheimer's disease by transcriptomic data

Identification of the molecular subgroups in Alzheimer's disease by transcriptomic data

He Li, Meiqi Wei, Tianyuan Ye, Yiduan Liu, Dongmei Qi, Xiaorui Cheng

What if Alzheimer’s disease is not one illness following one path, but several different biological problems hiding under the same diagnosis? This study found three distinct patterns in affected brains.

RadicalPy: A Tool for Spin Dynamics Simulations

RadicalPy: A Tool for Spin Dynamics Simulations

Lewis M. Antill, Emil Vatai

A tiny chemical reaction may help explain how migratory animals sense Earth’s magnetic field. But testing that idea has often required difficult simulations, and some biological results have been hard to reproduce.

Citizen scientists reveal small but concentrated amounts of fragmented microplastic on Arctic beaches

Citizen scientists reveal small but concentrated amounts of fragmented microplastic on Arctic beaches

Franco Pasolini, Bruno Walther, Melanie Bergmann

The Arctic can look untouched, yet a single beach sample held thousands of tiny plastic fibres. The surprising part is not just that plastic arrived there, it may be breaking apart there too.

Effectiveness of External Precooling and Vibration Induced by BUZZY on Pain and Anxiety During Inferior Alveolar Nerve Block Injection in Children

Effectiveness of External Precooling and Vibration Induced by BUZZY on Pain and Anxiety During Inferior Alveolar Nerve Block Injection in Children

Reyhane Narimany, Reyhaneh Faghihian, Mehdi Jafarzadeh Samani

A small device combines cooling and vibration to make a dental injection less frightening for children. But when it was tested, the reassuring sensation did not clearly reduce either pain or anxiety.

Comparative study of the bronchodilator efficacy and adverse effects of salbutamol and hyoscine butylbromide in horses with severe asthma

Comparative study of the bronchodilator efficacy and adverse effects of salbutamol and hyoscine butylbromide in horses with severe asthma

Berta Mozo Vives, Sophie Mainguy‐Seers, Jean‐Pierre Lavoie

When a horse cannot breathe, two medicines can open its narrowed airways quickly. But the treatment that lasts longer may also be the one that avoids problems with the heart and gut.

A Plasmonic Optoelectronic Resistive Random‐Access Memory for In‐Sensor Color Image Cryptography

A Plasmonic Optoelectronic Resistive Random‐Access Memory for In‐Sensor Color Image Cryptography

Quan Yang, Yu Kang, Chengchun Zhang, Haohan Chen, Tianjiao Zhang, Zheng Bian, Xiangwei Su, Wei Xu, Jiabao Sun, Pan Wang, Yang Xu, Bin Yu, Yuda Zhao

What if a camera pixel could recognize color, store what it saw, and create a fresh secret key before the image ever left the sensor? This paper builds a device designed to do exactly that.
