Physicists employ synthetic complex frequency waves to overcome optical loss in superlenses

Posted by in categories: biotech/medical, nanotechnology

A collaborative research team led by Interim Head of Physics Professor Shuang Zhang from The University of Hong Kong (HKU), along with National Center for Nanoscience and Technology, Imperial College London and University of California, Berkeley, has proposed a new synthetic complex frequency wave (CFW) approach to address optical loss in superimaging demonstration. The research findings were recently published in the journal Science.

Imaging plays an important role in many fields, including biology, medicine and material science. Optical microscopes use light to obtain imaging of miniscule objects. However, conventional microscopes can only resolve feature sizes in the order of the optical wavelength at best, known as the .

To overcome the diffraction limit, Sir John Pendry from Imperial College London introduced the concept of superlenses, which can be constructed from negative index media or noble metals like silver. Subsequently, Professor Xiang Zhang, the current President and Vice-Chancellor of HKU, along with his then team at the University of California, Berkeley, experimentally demonstrated superimaging using both a silver thin film and a silver/dielectric multilayer stack.

A stable and replicable neural signature of lifespan adversity in the adult brain

Posted by in category: neuroscience

In a birth cohort, Holz et al. found widespread structural brain changes at the age of 25 years as a function of adversity. This pattern was replicated at the age of 33 years and in another cohort. Individual-level volume reductions on top of this pattern predicted anxiety.

Launch Roundup: SpaceX to launch four missions, Progress MS-24 to resupply ISS

Posted by in categories: internet, space

Following several launch delays last week, the week of Aug. 21 through Aug. 27 is set to see seven launches marking the 129th through 135th orbital launch attempts of 2023.

Starting the week off, SpaceX will launch two back-to-back Starlink missions from Space Launch Complex (SLC) 4 East at the Vandenberg Space Force Base (VSFB) and from SLC-40 at the Cape Canaveral Space Force Station (CCSFS). Next, Russia will launch its Progress resupply mission, followed by Rocket Lab’s launch of “We Love the Nightlife.” SpaceX will then launch the Crew-7 mission from Launch Complex 39A (LC-39A); JAXA will launch the SLIM and XRISM mission; SpaceX is expected to end the week off with another Starlink mission from SLC-40.

240-Million-Year-Old Giant Amphibian Discovered in Retaining Wall

Posted by in category: life extension

O.o!!! The longevity of this complex organism could reveal new avenues for immortality.


Arenaerpeton supinatus was discovered in rocks cut from a nearby quarry that were intended for the building of a garden wall.

A 240-million-year-old fossil of an amphibian was found in a retaining wall in the 1990s. This significant find has now been formally named and described by scientists at the University of New South Wales (UNSW Sydney) and the Australian Museum.

The Kardashev Scale — Can We Advance Beyond a Type 3 Civilization?

Posted by in categories: computing, space

A type 5 civilization often seen as unattainable is actually quite possible. We could have computers to use a developer mode to solve all sorts of problems like the entropy of the universe and even stop the entropy of the earth or stop meteorites from hitting earth with a computer click. This could easily be attainable with technological singularities leading to a new understanding of our universe but should be considered to essentially stop almost any problem to earth and beyond.


Type 1 civilization designation on the Kardashev scale may be possible in the next 100 years, which could influence the survival of mankind.

Forecasting the progression of human civilization on the Kardashev Scale through 2060 with a machine learning approach

Posted by in categories: food, robotics/AI

Throughout the history of human civilization, energy has been holding an imperative role in humanity’s progress1. Especially in the past few centuries, innovations in the harnessing of power have catalyzed humanity’s rapid growth2. Energy remains a key driver of human development3, with each revolution in industry and agriculture highlighting human’s reliance on it. Revolution in the eighteenth century was a turning point. The development of steam engines powered by fossil fuels led to significant technological progress4. Electricity has then opened new possibilities for the future5. Humanity has grown at a compound annual rate of 2.43% from 1965 to 2020, demonstrating our continued increasing demand for and consumption of energy6,7. However, the pace at which human being can progress as a civilization in the future remains uncertain.

While mankind was establishing its identity in the universe, insatiable human curiosity over the realm of civilization peaked in the 1960s8, which led to deeper cogitation of the concept of civilization. Providing that some of the extraterrestrial civilizations are highly likely million years more advanced than mankind, Soviet astrophysicist Nikolai Kardashev proposed a scale to classifies a civilization’s technological development based on its energy consumption9, which was later known as the Kardashev Scale. The scale initially categorized civilizations into three types. Type 1 is known as the planetary civilization, which features the capability of harnessing and utilizing all forms of energies that can be reached on the host planet, such as wind, solar, and geothermal power; Type 2 and 3, known as the stellar and galactic civilizations, respectively, are capable of extracting and utilizing all energy created by their respective systems9. Yet, such a scale proved lackluster in the quantitative presentation of the civilization types. Subsequently, Carl Sagan furthered the Kardashev Scale with data extrapolation, and proposed a continuous function quantifying the Kardashev Scale in index K10
