Scientists have created a communication network entirely based on light that enables seamless connectivity across space, air, and underwater environments. The new network design combines different types of light sources to ensure connectivity no matter the environment.

“In today’s world, data transmission is critical for communication, navigation, emergency response, research, and commercial activities,” said research team leader Yongjin Wang from Nanjing University of Posts and Telecommunications and Suzhou Lighting Chip Monolithic Optoelectronics Technology Co. Ltd., both in China. “This new wireless network enables uninterrupted connectivity across environments, facilitating two-way real-time data transmission between the network nodes that carry out communication and data exchange within and between networks.”

University of Waterloo researchers have created a new technology that can remove harmful nanoplastics from contaminated water with 94% efficiency. The study, “Utilization of epoxy thermoset waste to produce activated carbon for the remediation of nano-plastic contaminated wastewater,” was published in the journal Separation and Purification Technology.

Can virtual reality (VR) be tailored to explore larger areas and allow users to “walk” around their environment? This is what a recent study published in IEEE Transactions on Visualization and Computer Graphics hopes to address as a team of international researchers have developed a new VR system called RedirectedDoors+ that can allow users to expand their environments beyond the real-world physical boundaries, such as walls and doors. This study holds the potential to not only expand VR environments but also drastically reduce the real-world environments that are typically required for VR experiences.

“Our system, which built upon an existing visuo-haptic door-opening redirection technique, allows participants to subtly manipulate the walking direction while opening doors in VR, guiding them away from real walls,” said Dr. Kazuyuki Fujita, who is an assistant professor in the Research Institute of Electrical Communication (RIEC) at Tohoku University and a co-author on the study. “At the same time, our system reproduces the realistic haptics of touching a doorknob, enhancing the quality of the experience.”

Measles outbreaks are growing globally.

Seven additional states have reported measles cases since the CDC issued an emergency warning at the end of January.

The recently approved drug motixafortide may help improve stem cell transplants for people with multiple myeloma. Learn more about this treatment:

However, Dr. Schulz cautioned, this finding is not definitive because the two drugs were not tested head-to-head in a randomized trial. A randomized clinical trial comparing the drugs “would have been a better and fairer comparison,” he said, since plerixafor and motixafortide both work by blocking a chemical signal that tells stem cells to stay in the bone marrow.

Finally, Dr. Crees and his colleagues did a series of experiments looking at the different types of blood-forming stem cells mobilized by G-CSF plus placebo, motixafortide, or plerixafor.

Researchers describe a newly observed role for the protein Cyclin Dependent Kinase 9 (CDK9) in regulating DNA repair during cellular division, where errors can become the origin of cancerous tumor growth. Through a process called phosphorylation, the experiment simulated the interaction of CDK9 with the other proteins and genes involved in cell division and cancerous tumor growth.
