New technology to improve worlds most sensitive scientific instruments
A new technology that can improve gravitational-wave detectors, one of the most sensitive instruments used by scientific researchers, has been pioneered by physicists at The University of Western Australia in collaboration with an international team of researchers.
The new technology allows the world’s existing gravitational wave detectors to achieve a sensitivity that was previously thought only to be achievable by building much bigger detectors.
The paper, published in Communications Physics, was led by the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) at UWA, in collaboration with the ARC Centre of Excellence for Engineered Quantum Systems, the Niels Bohr Institute in Copenhagen and the California Institute of Technology in Pasadena.

New hope for treating chronic pain without opioids
According to some estimates, chronic pain affects up to 40% of Americans, and treating it frustrates both clinicians and patients–a frustration that’s often compounded by a hesitation to prescribe opioids for pain.
A new study from the University of Michigan School of Dentistry confirms that a low dose of a drug called naltrexone is a good option for patients with orofacial and chronic pain, without the risk of addiction, said first author Elizabeth Hatfield, a clinical lecturer in the Department of Oral and Maxillofacial Surgery and Hospital Dentistry.
Naltrexone is a semisynthetic opioid first developed in 1963 as an oral alternative to naloxone, the nasal spray used to reverse opioid drug overdoses. When prescribed at doses of 50 to 100 milligrams, naltrexone blocks the effects of alcohol and opioids.
