Scientists from the International Centre for Radio Astronomy Research (ICRAR) and the University of Western Australia (UWA) have set a world record for the most stable transmission of a laser signal through the atmosphere.

In a study published today in the journal Nature Communications, Australian researchers teamed up with researchers from the French National Centre for Space Studies (CNES) and the French metrology lab Systèmes de Référence Temps-Espace (SYRTE) at Paris Observatory.

The team set the world record for the most stable laser transmission by combining the Aussies’ phase stabilization technology with advanced self-guiding optical terminals. Together, these technologies allowed laser signals to be sent from one point to another without interference from the atmosphere.

“This is the first study to use pressure to control this stability, and it really opens up a lot of possibilities,” Yu Lin, researcher at the Stanford Institute for Materials and Energy Sciences (SIMES), said in a statement.

“Now that we’ve found this optimal way to prepare the material, there’s potential for scaling it up for industrial production, and for using this same approach to manipulate other perovskite phases,” Lin added.

The “black” phase, the one successfully stabilized by the scientists, of perovskite has intrigued scientists for years since it has been found to be extremely efficient in converting sunlight to electricity, making it the Holy Grail for solar panel technology.

Prostate cancer is one of the most common cancers among men. Patients are determined to have prostate cancer primarily based on PSA, a cancer factor in blood. However, as diagnostic accuracy is as low as 30%, a considerable number of patients undergo additional invasive biopsy and thus suffer from resultant side effects, such as bleeding and pain.

The Korea Institute of Science and Technology (KIST) announced that the collaborative research team led by Dr. Kwan Hyi Lee from the Biomaterials Research Center and Professor In Gab Jeong from Asan Medical Center developed a technique for diagnosing prostate cancer from urine within only 20 minutes with almost 100% accuracy. The research team developed this technique by introducing a smart AI analysis method to an electrical-signal-based ultrasensitive biosensor.

As a noninvasive method, a diagnostic test using urine is convenient for patients and does not need invasive biopsy, thereby diagnosing cancer without side effects. However, as the concentration of cancer factors is low in urine, urine-based biosensors are only used for classifying risk groups rather than for precise diagnosis thus far.

The maximal reduction for biological age when using the biological age calculator, Phenotypic Age, is ~20 years. In other words, if I’m 80 years old and my biomarkers are all reflective of youth, the lowest possible biological age will be ~60 years old. One reason for that is the inclusion of chronological age in the prediction of biological age, which adds strength to the correlation while simultaneously limiting the maximal biological age reduction.

To account for the possibility that youthful biomarkers at an older chronological age can yield a biological age that is more than 20 years younger, it’s important to quantify biological age using a tool that doesn’t include chronological age in its calculation. Aging.ai fits that criterion, and in the video I present biological age data with use of aging.ai for 24 blood tests since 2009.

The reusable spaceplane concept seemed to die with the end of NASA’s Space Shuttle. Could the spaceplane rise again in the 21st Century?

Update (8:15 p.m. Thursday): SpaceX is now targeting no earlier than 9:40 a.m. Saturday, Jan. 23, for this launch. This also means weather odds decline from 80% “go” to 60% “go.”

SpaceX teams at Cape Canaveral Space Force Station are set for the company’s next launch on Friday, a unique mission that will hug the Florida coast as it flies a southern trajectory.

If everything goes as planned, a previously flown Falcon 9 will vault off Launch Complex 40 at 9:24 a.m. and turn southeast, placing its mission on a sun-synchronous – or nearly polar – trajectory. Friday’s launch window will remain open for about an hour.

Great new episode with University of Arizona planetary geophysicist Erik Asphaug who talks candidly about what we know and don’t know about the structure of our inner solar system. Well worth a listen.

Planetary geophysicist Erik Asphaug of the University of Arizona discusses what we really know about our solar system; its age; its formation; and its evolution. Asphaug also addresses some major puzzles. Is our solar system truly anomalous? Is the composition and spacing of our eight planets also anomalous? And what we need to do to further planetary science.
