There are more than 80 peptide drugs on the global market and about twice as many in clinical development. Due to their beneficial properties, these biomolecules play already an important role in the treatment of diseases. In
A team of Russian scientists from NUST MISIS, Tomsk Polytechnic University (TPU) and Boreskov Institute of Catalysis has suggested a new approach to modifying the combustion behavior of coal. The addition of copper salts reduces the content of unburnt carbon in ash residue by 3.1 times and CO content in the gaseous combustion products by 40%, the scientists found. The research was published in

Global emissions of a potent substance notorious for depleting the Earth s ozone layer - the protective barrier which absorbs the Sun s harmful UV rays - have fallen rapidly and are now back on the decline, according to new research.
Two international studies published today in
Nature, show emissions of CFC-11, one of the many chlorofluorocarbon (CFC) chemicals once widely used in refrigerators and insulating foams, are back on the decline less than two years after the exposure of their shock resurgence in the wake of suspected rogue production.

The research team led by Masakazu Ohara, graduate student of the Department of Computer Science and Engineering at Toyohashi University of Technology (student in the Leading Program doctoral program); Associate Professor Kowa Koida of the Electronics-Inspired Interdisciplinary Research Institute; and Associate Professor Juno Kim of the University of New South Wales (Australia) discovered that when people judge the thickness of an object, objects with glass-like transparent optical properties are perceived to be flatter than they actually are. It was previously known that objects made of metallic or glossy materials are perceived to be thicker than what they are, but now the current research has identified that transparent properties surprisingly have the opposite effect.

A description of gravity compatible with the principles of quantum mechanics has long been a widely pursued goal in physics. Existing theories of this quantum gravity often involve mathematical corrections to Heisenberg s Uncertainty Principle (HUP), which quantifies the inherent limits in the accuracy of any quantum measurement. These corrections arise when gravitational interactions are considered, leading to a Generalized Uncertainty Principle (GUP). Two specific GUP models are often used: the first modifies the HUP with a linear correction, while the second introduces a quadratic one. Through new research published in
EPJ C, Serena Giardino and Vincenzo Salzano at the University of Szczecin in Poland have used well-established cosmological observations to place tighter constraints on the quadratic model, while discrediting the linear model.
