Tokyo CNN  —  Nine crew members remain missing after a cargo ship capsized off Japan’s Nagasaki prefecture on Wednesday, the Japan Coast Guard told CNN. The coast guard said it received a distress signal from the Hong Kong-flagged vessel Jin Tian late on Tuesday night as it cruised 110 kilometers…

Ukraine wants longer range missiles as Russia learns from its mistakes | CNN

CNN  —  Ukrainian officials say the Russians are learning from their battlefield mistakes and making it harder for Ukraine’s missiles to hit their ammunition depots and logistics hubs. That’s why, they say, Ukraine needs longer range missiles that can reach inside Russia. They also believe the appointment of Gen. Valery…

What travel warnings do other nations give their citizens about US violence? | CNN

CNN  —  American travelers – at least those of the cautious variety – might be familiar with the US State Department’s travel advisories. The agency monitors the world for potential trouble and issues warnings from “Level 1: Exercise Normal Precautions” to “Level 4: Do Not Travel,” alerting would-be visitors to…

Fish sensory organ key to improving navigational skills of underwater robots

Scientists, led by University of Bristol, have been studying a fish sensory organ to understand cues for collective behaviour which could be employed on underwater robots. This work was centred around the lateral line sensing organ in African cichlid fish, but found in almost all fish species, that enables them…

Plasma thrusters used on satellites could be much more powerful: It was believed that running more propellant through a Hall thruster would wreck its efficiency, but new experiments suggest they might power a crewed mission to Mars

It was believed that Hall thrusters, an efficient kind of electric propulsion widely used in orbit, need to be large to produce a lot of thrust. Now, a new study from the University of Michigan suggests that smaller Hall thrusters can generate much more thrust — potentially making them candidates…

Pop-up electrode device could help with 3D mapping of the brain

Understanding the neural interface within the brain is critical to understanding aging, learning, disease progression and more. Existing methods for studying neurons in animal brains to better understand human brains, however, all carry limitations, from being too invasive to not detecting enough information. A newly developed, pop-up electrode device could…

Researchers identify neurons that ‘learn’ to smell a threat

Whether conscious of it or not, when entering a new space, we use our sense of smell to assess whether it is safe or a threat. In fact, for much of the animal kingdom, this ability is necessary for survival and reproduction. Researchers at the Del Monte Institute for Neuroscience…

Biomedical institutions agree on a set of open science practices to monitor

Eighty stakeholders from twenty major biomedical research institutions across the globe have agreed upon a list of 19 open science practices to be implemented and monitored. The study, led by Dr. Kelly Cobey, Scientist and Director of the Open Science and Meta Research Program at the University of Ottawa Heart…

Actin affects the spread of cancer in several ways

Metastases occur when cancer cells leave a primary tumor and spread throughout the body. For this, they have to break connections with neighboring cells and migrate to other tissues. Both processes are promoted by signalling molecules released by the cancer cells, which thereby increase the malignancy of tumors. A research…
