Ordering coffee with your feet

University of Waterloo

Imagine controlling apps with your feet while you walk. This concept is the focus of new research which explores using gait gestures – intentional variations in how you walk – as controls for augmented reality (AR) devices.

Neutron star mountains would cause ripples in space-time

DOE/US Department of Energy

The surface features of neutron stars are largely unknown. Nuclear theorists explored mountain building mechanisms active on the moons and planets in our solar system. Some of these mechanisms suggest that neutron stars are likely to have mountains. Neutron star mountains would be much more massive than any on Earth--so massive that gravity just from these mountains could produce ripples in the fabric of space and time.

PolyU research underscores the importance of interdisciplinary services in pediatric palliative care

The Hong Kong Polytechnic University

Medical advancements have extended the lifespans of children and adolescents diagnosed with life-limiting conditions, resulting in a greater need for healthcare resources and expanded caregiver services. The Hong Kong Polytechnic University (PolyU) researchers have studied the physical and non-physical needs of patients, parents and healthcare providers to enhance the provision of holistic healthcare services.

AI tackles disruptive tearing instability in fusion plasma

DOE/US Department of Energy

Instabilities in the plasma in a tokamak device can cause disruptions that result in rapid loss of plasma confinement and the release of large amounts of energy. Current approaches can suppress one type of disruption, tearing instabilities, after they form. Here, researchers tested a method using AI/deep reinforcement learning that instead adjusts plasma conditions in real-time to avoid these instabilities from developing in the first place.

New approach merges theoretical fundamentals with experimental studies of the proton’s structure

DOE/US Department of Energy

New quantum chromodynamics (QCD) research provides physicists with the tools needed to relate the physics of specific particle collisions with the internal structure of the involved particles. These tools will help scientists relate theory and experiments into how quarks and gluons bind under the influence of QCD.

New ‘explant’ technique predicts a tumor’s responsiveness to breast cancer treatment

University of Leicester

Cancer researchers at the University of Leicester have developed a technique that could predict how well some breast cancer patients will respond to chemotherapy and antibody-directed cancer treatments.

New method effectively improves the angular-temporal resolution of attoclock technology

Ultrafast Science

The advancement of laser manipulating and shaping technology enables the precise control of strong field electron dynamics on a subcycle time scale which helps to resolve this critical issue. Two-color fields, which are the coherent overlap of the strong driving laser fields and its second harmonic field acting as a perturbation, provide an easy-to-implement method to shape the tunnelling electron wavepacket and control the coherent radiation.

Coherent terahertz wave generation from mono- and multi-layer MoS2 through quantum interference

Ultrafast Science

A research team in the Center for Terahertz waves and School of Precision Instrument & Opto-electronics Engineering at Tianjin University in China experimentally investigates the THz wave generation from mono- and multi-layer MoS₂ through QI under two-color field excitation, demonstrating the coherently controllable THz radiation (i.e., coherent injected photocurrent) from MoS₂ through an all-optical method. This work has been published in Ultrafast Science.

HKUMed study: Hip fractures may trigger cardiovascular events; Risk five times higher in patients with heart failure

The University of Hong Kong

A research team in the Department of Pharmacology and Pharmacy, LKS Faculty of Medicine, the University of Hong Kong (HKUMed), found that hip fractures not only result in both physical and psychological injuries, but may also induce adverse cardiovascular events. In particular, hip fracture patients with pre-existing cardiac conditions are associated with a significantly higher risk of cardiovascular events (CVEs) and mortality, poorer prognosis, and greater health service utilisation. The research employed big data and artificial intelligence (AI) to uncover hidden clinical characteristics of hip fracture patients of different ethnicities, based on the electronic health records from Hong Kong and the United Kingdom (UK) of over 100,000 patients with hip fractures. The findings could enhance the current management of hip fracture patients and provide valuable insights into precision medicine in hip fracture patients. The study has been published in Nature Communications [link to the publication].
