Researchers from the RIKEN Cluster for Pioneering Research have made observations of a new magnetar, called Swift J1818.0-1607, which challenges current knowledge about two types of extreme stars, known as magnetars and pulsars. The research, just published in The Astrophysical Journal, was done using the Neutron star Interior Composition Explorer (NICER), an X-ray instrument aboard the International Space Station. Magnetars are a subtype of pulsars, which are neutron stars — degenerate stars that failed to become black holes but instead became extremely dense bodies composed mostly of neutrons.

Magnetars as well as some young rotation-powered pulsars — another type of pulsar — emit powerful X-ray beams, but the mechanism i...

Researchers 3D Print unique Micro-Scale Fluid channels used for Medical Testing

Researchers at the University of Minnesota are the first to 3D print microfluidic channels on a curved surface, providing the initial step for someday printing them directly on the skin for real-time sensing of bodily fluids. Credit: McAlpine Group, University of Minnesota.

In a groundbreaking new study, researchers at the University of Minnesota, in collaboration with the U.S. Army Combat Capabilities Development Command Soldier Center, have 3D printed unique fluid channels at the micron scale that could automate production of diagnostics, sensors, and assays used for a variety of medical tests and other applications.

The team is the first to 3D print these structures on a curved surface, providing the initial step for someday printing them directly on the skin for real-time sensin...

Preliminary results of 2 large Immune Therapy studies show promise in Advanced Cervical Cancer

Preliminary results from two independent, phase II clinical trials investigating a new PD-1 (programmed cell death protein 1)-based immune therapy for metastatic cervical cancer suggest potential new treatment options for a disease that currently has limited effective options and disproportionately impacts younger women.

David O’Malley, MD, of The Ohio State University Comprehensive Cancer Center — Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC — James), presented the preliminary study results at the European Society for Medical Oncology (ESMO) Virtual Congress 2020 on Sept. 18. O’Malley was the lead presenter for both trials, which were sponsored by Agenus Inc.

Each study involved more than 150 patients with recurrent or metastatic cervical can...

‘Trojan horse’ approach to kill Cancer Cells Without using Drugs

Cancer cells are killed in lab experiments and tumour growth reduced in mice, using a new approach that turns a nanoparticle into a ‘Trojan horse’ that causes cancer cells to self-destruct, a research team at the Nanyang Technological University, Singapore (NTU Singapore) has found.

The researchers created their ‘Trojan horse’ nanoparticle by coating it with a specific amino acid — L-phenylalanine — that cancer cells rely on, along with other similar amino acids, to survive and grow...
