Purdue University innovators developed a stabilized form of human calcitonin, which is a peptide drug already used for people with osteoporosis. Researchers at Purdue created a prodrug form of the peptide hormone to increase its effectiveness as an osteoporosis treatment.

Experts in optical physics have developed a new way to see inside living cells in greater detail using existing microscopy technology and without needing to add stains or fluorescent dyes.
Since individual cells are almost translucent, microscope cameras must detect extremely subtle differences in the light passing through parts of the cell. Those differences are known as the phase of the light. Camera image sensors are limited by what amount of light phase difference they can detect, referred to as dynamic range.

Research conducted in the Light-Matter Interactions for Quantum Technologies Unit at the Okinawa Institute of Science and Technology Graduate University (OIST) has revealed the presence of small microplastics in the ocean surrounding Okinawa. The study was published in
Science of the Total Environment. There s been a considerable amount of research on larger plastic pieces in the ocean, said Christina Ripken, PhD student in the Unit and lead author of the paper. But the smaller pieces, those that are less than 5mm in size, haven t been in the spotlight, so it was important to identify whether they re present and the impacts they might have on living organisms.

Catalysis is an area of chemical sciences which has fascinated a wide range of academicians, researchers, chemical technologists and industries throughout the world. Progress in this field has been made owing to the thrust provided by this research and commercial interest. The field of catalysis is interdisciplinary by its nature, as it requires knowledge of organic synthesis, coordination and organometallic chemistry, reaction kinetics and mechanisms, stereo-chemical concepts and materials science.
Fundamentals and Prospects of Catalysis highlights many important topics and sub-disciplines in catalysis by presenting 7 chapters on different but varied catalytic processes. This volume presents the following topics: Organocatalytic Asymmetric Synthesis of Spiroacetals and Bridged Acetals

The gallium selenide monolayer has been recently discovered to have an alternative crystal structure and has diverse potential applications in electronics. Understanding its properties is crucial to understand its functions. Now, scientists from the Japan Advanced Institute of Science and Technology and the University of Tokyo have explored its structural stability, electronic states, and transformation of crystal phases.
Solid materials comprise a symmetric arrangement of atoms that confer properties like conductivity, strength, and durability. Changes in size can change this arrangement, thereby changing the overall properties of the material. For instance, the electrical, chemical, optical and mechanical properties of certain materials can change as we move towards the nano scale. Science now lets us study the differences in properties across various dimensions right from monolayer (atomic) level.
