Circa 2016 This gives more exacting detail of the Tasmanian devils resistance to cancer.
A recently emerged infectious cancer has caused the near extinction of the Tasmanian devil, but some populations persist. Here, Epstein et al. provide evidence for possible resistance via rapid evolution in two genomic regions that contain cancer-related immune response genes.
Researchers have developed a new chip-based beam steering technology that provides a promising route to small, cost-effective, and high-performance lidar systems. Lidar, or light detection and ranging, uses laser pulses to acquire 3D information about a scene or object. It is used in a wide range of applications such as autonomous driving, 3D holography, biomedical sensing, free-space optical communications, and virtual reality.
“Optical beam steering is a key technology for lidar systems, but conventional mechanical-based beam steering systems are bulky, expensive, sensitive to vibration, and limited in speed,” said research team leader Hao Hu from the Technical University of Denmark. “Although devices known as chip-based optical phased arrays (OPAs) can quickly and precisely steer light in a non-mechanical way, so far, these devices have had poor beam quality and a field of view typically below 100 degrees.”
Too much screen use has been linked to obesity and psychological problems. Now a new study has identified a new problem—a study in fruit flies suggests our basic cellular functions could be impacted by the blue light emitted by these devices. These results are published in Frontiers in Aging.
“Excessive exposure to blue light from everyday devices, such as TVs, laptops, and phones, may have detrimental effects on a wide range of cells in our body, from skin and fat cells, to sensory neurons,” said Dr. Jadwiga Giebultowicz, a professor at the Department of Integrative Biology at Oregon State University and senior author of this study. “We are the first to show that the levels of specific metabolites—chemicals that are essential for cells to function correctly—are altered in fruit flies exposed to blue light.”
“Our study suggests that avoidance of excessive blue light exposure may be a good anti-aging strategy,” advised Giebultowicz.
The thermal radiation emitted by the human body is predominantly in the long-wave infrared region (8–14 μm), which is characterized by low photon energy and low power intensity.
Recently, a research team led by Associate Prof. Lu Xiaowei, Prof. Jiang Peng and Prof. Bao Xinhe from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) designed a highly sensitive long-wave infrared detector that enables low-power non-contact human-machine interaction.

Alloy that exceeds the strength and ductility of other state-of-the-art additively manufactured materials. This breakthrough could lead to higher-performance components for applications in aerospace, medicine, energy, and transportation. The work was done by researchers from the University of Massachusetts Amherst and the Georgia Institute of Technology. It was led by Wen Chen, assistant professor of mechanical and industrial engineering at UMass, and Ting Zhu, professor of mechanical engineering at Georgia Tech, will be published today (August 3, 2022) in the journal Nature.
High entropy alloys (HEAs) have become increasingly popular as a new paradigm in materials science over the past 15 years. They are comprised of five or more elements in near-equal proportions and offer the ability to create a near-infinite number of unique combinations for alloy design. Traditional alloys, such as brass, stainless steel, carbon steel, and bronze, contain a primary element combined with one or more trace elements.
Scientists say medication also used after undergoing an organ transplant is capable of extending life with only brief use
COLOGNE, Germany — A drug that patients normally take during cancer therapy may have the power to increase the human lifespan, a new study reveals. Researchers in Germany say rapamycin can cause side-effects when patients take it as a lifelong anti-aging treatment. However, their new report finds even brief usage can have a dramatic impact on longevity while cutting down on side-effects.

Online gaming and other types of online social interaction have become increasingly popular during the pandemic, and increased remote working and investments in social technology will likely see this trend continue.
Carnegie Mellon mechanical engineering researchers have developed a new scalable and reproducible manufacturing technique that could accelerate the mainstream adoption and commercialization of soft and stretchable electronics.
The next generation of robotic technology will produce soft machines and robots that are safe and comfortable for direct physical interaction with humans and for use in fragile environments. Unlike rigid electronics, soft and stretchable electronics can be used to create wearable technologies and implantable electronics where safe physical contact with biological tissue and other delicate materials is essential.
Soft robots that safely handle delicate fruits and vegetables can improve food safety by preventing cross-contamination. Robots made from soft materials can brave the unexplored depths of the sea to collect delicate marine specimens. And the many biomedical applications for soft robots include wearable and assistive devices, prostheses, soft tools for surgery, drug delivery devices, and artificial organ function.
