With clock ticking, sustainable transport key to Global Goals
2021-10-16 10:10
From electric cars and buses to zero-carbon producing energy sources, new and emerging technologies along with innovative policy changes, are critical for combating climate change. But to be effective, they must ensure that transport strategies benefit everyone, including the poorest, according to a new UN multi-agency report launched on Tuesday.
The “clock is ticking on our 2030 timeline” to achieve the S...
Ytterbium based infrared light source of record intensity
2021-10-15 10:09
Scientists from the P.N. Lebedev Physical Institute with colleagues from the Bauman Moscow State Technical University, the A.N.Nesmeyanov Institute of Organoelement Compounds, the N.D.Zelinsky Institute of Organic Chemistry and the N.E. NS Kurnakov synthesized new materials based on the rare earth metal ytterbium. They are capable of emitting infrared light with record efficiency in response to exposure to ...
German transport drone carries up to 200 kg of cargo over a distance of 40 km
2021-10-14 10:03
The German company Volocopter has shown tests of a heavy cargo drone: it is capable of carrying 200 kg of cargo over 40 km.The first video of the VoloDrone cargo drone has been published, it has been developed since 2019. The drone was able to lift the box into the air to a height of 22 m and in three minutes moved it to the nearest parking lot.One full charge of the batteries is enough to transport a load ...
Antioxidants to prevent Alzheimer's disease
2021-10-13 14:50
A study by doctoral student Mohamed Raafet Ben Hedher and doctoral student Mohamed Haddad of the National Institute for Scientific Research (INRS) showed that an imbalance between oxidation and antioxidants in the blood is an early sign of Alzheimer's, not a consequence. This breakthrough, made by researchers led by Professor Charles Ramassa, paves the way for preventive intervention: antioxidant supple...
Deep Learning Helps Create Proteins with New Functions
2021-10-12 18:17
Protein engineering is a branch of biotechnology that deals with the search and creation of proteins with improved or completely new functions. One of the main experimental methods of protein engineering is directed evolution, in which a protein of interest to scientists passes through several cycles of mutagenesis and subsequent selection of successful variants. While this approach is effective, it does no...
Extinct Ground Sloth Mylodon Was Not a Vegetarian
2021-10-11 10:43
Today, all six living sloth species are relatively small plant-eating tree-dwellers. But a new study suggests that Mylodon—a giant ground sloth that lived in South America until about 10,000 to 12,000 years ago—was not a strict vegetarian, at times eating meat or other animal protein in addition to plants.
“We now have strong evidence contradicting the long-standing presumption that all sloths were obligat...
The researchers announced the photon-phonon interaction
2021-10-10 10:20
A new study by a team of researchers at City College of New York has discovered a new way of combining two different states of matter. For the first time, topological photons - light - have been combined with lattice vibrations, also known as phonons, to reliably and controllably control their propagation.The study used topological photonics - a new direction in photonics, which uses the fundamental ideas o...
