The concrete industry is enormous. But, this industry is responsible for around 7% of the world’s carbon dioxide emissions. And a large proportion of this 7% is due to the necessary use of calcium, which is usually obtained by burning limestone. Now, scientists at the University of Tokyo have found a new way to reduce…
Using the world’s most powerful radio telescope Low-Frequency Array (LOFAR), Dr. Benjamin Pope from the University of Queensland and colleagues at the Dutch national observatory ASTRON have searched for planets. Recently, the team has discovered radio waves blasting out from distant stars, indicating the presence of hidden planets. Scientists have discovered radio signals from 19…
Ramadan fasting is practiced by hundreds of millions every year. During this month, Muslims fast every day from dawn to sunset. Fasting during Ramadan changes to diet and lifestyle dramatically. A new study from the Imperial College London scientists determined the effect of Ramadan fasting on blood pressure. Their study suggests that fasting during Ramadan…
Quasicrystals are a new class of solid that exhibits symmetries forbidden to ordinary periodic crystals. They have ordered structures but not the repeating patterns of ordinary crystals. It is also possible to manufacture them with exciting properties. They can be ultra-hard or super-slippery. They can absorb heat and light in unusual ways and exhibit exotic…
The usefulness of concrete does not end when it gets formed into a structure. Old concrete can be reused in several construction projects, depending on the material’s size and shape. People often hesitate to reuse concrete due to several concerns. But, EPFL researchers have shown that those concerns are largely unfounded. Using reinforced concrete blocks…
An international research team, led by the University of Canterbury‘s Professor Rudi Marquez, has developed a new wound gel that promises horses and humans. This new wound gel will be used to treat foot ulcers and kick-starts tissue regeneration. As scientists noted, it could have a significant impact on healing horses and humans alike. To…
Wearable technology is one of the fastest-advancing sectors of the broader technology industry, now outpacing the development of smartphones. From basic fitness trackers to virtual and augmented reality headsets, wearables are everywhere.  Engineers at the University of Arizona have introduced a new concept of tailoring a device directly to a person and using wireless power,…
NASA/ESA’s Hubble Space Telescope captured two interacting galaxies that are so intertwined, named Arp 91. Each galaxy has its names: the lower galaxy, which looks like a bright spot, is NGC 5953, and the oval-shaped galaxy to the upper right is NGC 5954. The dance of these galaxies takes place more than 100 million light-years…
Scientists at City College of New York have created a new way to combine two different states of matter. Scientists combined topological photons—light with lattice vibrations, also known as phonons, using this new approach. Doing so, they were able to manipulate their propagation in a robust and controllable way. Scientists used topological photonics, an emergent…
According to a new study by Australian National University (ANU), too much blood pressure is aging our brains. In the study, scientists found that optimal blood pressure keeps our brain at least six months younger than our actual age. A normal blood pressure level is less than 120/80 mmHg. On the other hand, the optimal…
