Tech Xplore / Nature-inspired navigation system helps robots traverse complex environments without GPS
Robots could soon be able to autonomously complete search and rescue missions, inspections, complex maintenance operations and various other real-world tasks. To do this, however, they should be able to smoothly navigate ...
Phys.org / Machine learning discovers quasars acting as lenses
Quasars acting as strong gravitational lenses are among the rarest finds in astronomy. Out of nearly 300,000 quasars cataloged in the Sloan Digital Sky Survey, only twelve candidates were identified, and just three confirmed. ...
Medical Xpress / Aging spleen creates toxic environment that forces T cells into self-protective but weakened state, study shows
Researchers at the Technion—Israel Institute of Technology Faculty of Biology have identified a unique mechanism involved in the aging of the immune system—along with a framework for enhancing its function in older individuals. ...
Medical Xpress / Novel imaging approach may improve treatment for spinal cord injuries
Northwestern Medicine investigators have developed a new imaging approach to more accurately assess blood flow in the spinal cord, a method that could be used to better inform treatment for neurological diseases and injuries, ...
Phys.org / Scientists map genetic distribution of maerl-forming algae across south-west Britain
A habitat-building coralline algae that provides a vital nursing ground for marine species and an important blue carbon ecosystem has been genetically mapped around south-west Britain in a first-of-its-kind study.
Phys.org / Forensic linguistics: How dark web criminals give themselves away with their language
Shannon McCoole ran one of the world's largest dark web child abuse forums for around three years in the early 2010s. The forum provided a secure online space in which those interested in abusing children could exchange images, ...
Medical Xpress / A time-sensitive genetic switch for sex-specific features of developing neurons
Researchers have identified that the precisely timed transcription of two genes named grim and reaper is responsible for the targeted death of neurons within the developing nervous system of female flies. This group of neurons ...
Medical Xpress / Pneumocystis pneumonia is striking unexpected patient groups, study shows
A seven-year study of 470 patients revealed that a severe fungal lung infection once mainly seen in specific high-risk groups is increasingly affecting elderly patients and those with common cancers who are not receiving ...
Phys.org / Scientists discover caves carved by water on Mars that may have once harbored life
If there is, or ever has been, life on Mars, the chances are it would exist in caves protected from the severe dust storms, extreme temperatures, and high radiation present on its surface. One place to focus our attention ...
Medical Xpress / Researchers find simple way to make kale healthier by pairing it with oil-based dressings
Think that kale salad you're eating is a superfood? Without the right ingredient it might not be living up to its hype. But don't worry.
Phys.org / Black hole mergers could give rise to observable gravitational-wave tails
Black holes, regions of spacetime in which gravity is so strong that nothing can escape, are intriguing and extensively studied cosmological phenomena. Einstein's general theory of relativity predicts that when two black ...
Phys.org / New computational tool helps scientists interpret complex single-cell data
Researchers from Turku Bioscience Center at the University of Turku, Finland, have developed a new computational method to interpret complex single-cell data. The method helps researchers identify and group cell types across ...
