Study Sheds New Light on the Link Between Oral Bacteria and Diseases

Credit: CC0 Public DomainInvestigators at Karolinska Institutet in Sweden have determined the microorganisms most typically discovered in intense oral diseases. Few such research have been done previously, and the group currently wishes that the investigation can deliver much deeper insight into the association in between dental germs and other diseases. The research is released...

Australian Public Asks For More Proactive Pet Laws

Public opinion is shifting to wanting a much more proactive approach to animal well-being rather than a reactive approach to animal cruelty.University of Adelaide specialists asked the Australian public about their perception of the penalties for animal cruelty.The court of public opinionRochelle Morton, a Ph.D. student from the University of Adelaide's School of Animal...

Quantum Sensors for GPS-free Orientation

Along each of the three axes of measurement, a mechanical accelerometer is connected to the reference mirror of the atom interferometer, resulting in a classic/quantum hybridization that permits continual acceleration measurement with an ultralow proclivity. Measurements of the three vector components are utilized to determine the acceleration vector in any direction. The sensor is...

Ancient Egyptians Might Have Used Branding Irons on Human Slaves

Several of the ancient Egyptian branding-irons — actually made of bronze — were too small for large animals like cattle and were probably used to brand human slaves. Credit: © The Trustees of the British Museum; (CC BY-NC-SA 4.0)A new research study proposes that small branding irons from ancient Egypt were most likely used to mark...

Researchers Discover Exotic Quantum State in Topological Insulators

Researchers at Princeton found that a material known as a topological insulator, made from the elements bismuth and bromine, exhibit specialized quantum behaviors normally seen only under extreme experimental conditions of high pressures and temperatures near absolute zero.

Electrons Zoom Along Quantum Highways in New Material

Scientists showed how MnBi6Te10, shown here in purple (tellurium), blue (bismuth) and green (manganese), can act as a magnetic topological insulator, conducting electrical current (blue) along a “quantum highway” without losing energy. The study revealed that a concerted action of different material defects is key to the quantum electronic properties. Credit: University of ChicagoQuantum...

Acts Like a Plastic But Conducts Like Metal

Credit: © fox17 / stock.adobe.comResearchers at the University of Chicago have found a means to produce a material that resembles plastic yet conducts electricity more like a metal.Like a metal?The research, released on Oct. 26 in Nature, shows how to produce a sort of material wherein the molecular fragments are shuffled and disordered but...

Cleaning Toxic ‘Protein Clumps’ Could Prevent Dementia

Credit: Queensland Brain InstituteThe clean-up of cellular "protein clumps" can prevent the beginning of some forms of dementia, according to new research from The University of Queensland.Scientists from the Queensland Brain Institute made the finding while emphasizing the relationship inbetween the enzyme Fyn and the protein Tau in frontotemporal dementia. The team, led by...
