China reveals plans to launch a fleet of mile-long solar panels into space to beam energy back to Earth by 2035 – and says the system could have the same output as a nuclear power station by 2050

By RYAN MORRISON  

  • Chinese officials have begun work on a new space-solar-power research centre
  • The researchers there will work out how to send power over very large distances
  • It is hoped solar panels orbiting 23,000 miles from Earth will send power back
  • The facility has a 25 acre exclusion zone in case of problems with wireless power 

China plans to launch a fleet of mile-long solar panels into space by 2035 and beam the energy back to Earth in a bid to meet its 2060 carbon neutral target. 

Reports suggest that once fully operational by 2050, the space-based solar array will send a similar amount of electricity into the grid as a nuclear power station.

3D Printer

A new nanoengineered bioink allows scientists to print 3D, anatomically accurate, multicellular blood vessels.

Researchers have designed a 3D-bioprinted model of a blood vessel that mimics its state of health and disease, thus paving the way for possible cardiovascular drug advancements with better precision.

Vascular diseases such as aneurysms, peripheral artery disease, and clots inside blood vessels account for 31% of global deaths. Despite this clinical burden, cardiovascular drug advancements have slowed over the past 20 years. The decrease in cardiovascular therapeutic development is attributed to the lack of efficiency in converting possible treatments into approved methods, specifically due to the discrepancy between studies that take place outside the body compared to inside. 
 
The team’s research aims to remodel current methodologies to minimize this gap and improve the translatability of these techniques by directing 3D bioprinting toward vascular medicine. This interdisciplinary and collaborative project was recently published in the journal Advanced Healthcare Materials. 
 
Bioprinting in 3D is an advanced manufacturing technique capable of producing unique, tissue-shaped constructs in a layer-by-layer fashion with embedded cells, making the arrangement more likely to mirror the native, multicellular makeup of vascular structures. A range of hydrogel bioinks was introduced to design these structures; however, there is a limitation in available bioinks that can mimic the vascular composition of native tissues. Current bioinks lack high printability and are unable to deposit a high density of living cells into complex 3D architectures, making them less effective.

Baidu Apollo unveils autonomous vehicle with no steering wheel or pedals

Human drivers may become a thing of the past.

by Mengyuan Ge 

Baidu’s autonomous driving unit, Apollo, has developed a new vehicle capable of Level 5 vehicle autonomy, meaning the car requires no human intervention during operation. Notably, it has no steering wheel, gas pedal, or brake pedal, signifying that drivers are completely unnecessary.

The “robocar,” as Baidu founder and CEO Robin Li called it, was showcased during a livestream event on Wednesday. It is equipped with two passenger seats, a large curved screen, an intelligent console, and electrochromic glass with varying tints based on natural brightness. This follows Apollo’s showcase of its Moon model in June.

During the event, Apollo indicated that the new vehicle will incorporate machine learning to analyze passengers’ needs and respond to verbal commands. In some scenarios, the system may even anticipate demands made by people in the vehicle.

Alzheimer's Disease

Genome-editing strategy developed for potential Alzheimer’s therapy

An international research team led by scientists from the Hong Kong University of Science and Technology (HKUST) has developed a novel strategy using brain-wide genome-editing technology that can reduce Alzheimer’s disease (AD) pathologies in genetically modified AD mouse models. This advanced technology offers immense potential to be translated as a novel long-acting therapeutic treatment for AD patients.

In China alone, over 500,000 patients are estimated to be living with a hereditary form of AD — familial Alzheimer’s disease (FAD), which is a congenital form of AD highly associated with family history. Although FAD has a clear genetic cause and can be diagnosed before cognitive problems occur, no effective treatment currently exists.

There is enormous potential in the use of genome-editing technology* as therapeutic strategies for diseases caused by inherited mutations, such as FAD. It is especially useful for correcting disease-causing genetic mutations before symptoms appear, for which it is considered a “once-and-for-all” treatment as its effects can last a lifetime. However, several hurdles have prevented its clinical development and application — most notably the lack of an effective, efficient, and non-invasive means to deliver genome-editing agents into the brain. Furthermore, existing genome-editing technologies are unable to generate beneficial outcomes throughout the whole brain.

Mazda Is Working on a New Hydrogen Rotary Engine: Report

Remember the RX-8 Hydrogen RE? Probably not, but it’s proof that Mazda has done this before.

BY CHRIS TSUI

While most of the automotive world pivots toward battery-electric, Mazda is apparently following in part-owner Toyota’s footsteps in betting on hydrogen. What’s more, the Hiroshima automaker is said to be pairing the niche energy tech with another niche propulsion method: the rotary. If a new report from Japan’s Best Car Web is to be believed, Mazda is currently working on a hydrogen rotary engine, that is, a rotary engine that runs on hydrogen instead of gasoline. 

Decrypted via Google Translate, “Although it is a small scale, development has progressed. As the world has suddenly turned to decarbonization, the view that ‘hydrogen rotary is an important technology’ is rapidly expanding,” a Mazda official reportedly told the publication.

UK looks at drones, 3D printing to fix its dimpled roads

By Ishveena Singh

The UK Department for Transport (DfT) is launching a multimillion-pound initiative to improve local roads across England. Among other things, this program aims to explore the use of drones and 3D printing technology when it comes to finding and fixing potholes.

According to a bunch of measures announced by Transport Secretary Grant Shapps, new and innovative technology such as drones and 3D printing will take center stage in helping England to perk up its dimpled roads that many have likened to the surface of the moon.  

The condition is so bad that councils in England and Wales had to fill up 1.7 million potholes in the financial year 2020-21 alone – which is equal to one being fixed every 19 seconds. So now, a red-faced government is committing funds to use advanced technology, such as drones to spot defects in roads and 3D printing to repair cracks.

Cancer

Cancer therapy breakthrough in vitro using self-assembled drugs

ONE of the most challenging aspects of cancer treatment is the huge variety of different tumours that can occur with each one potentially requiring a different solution because unfortunately, one drug does NOT fit all.

In addition, another major issue of many current drugs is their poor selectivity towards cancers resulting in problems such as normal tissue toxicity, severe side effects and the development of drug resistance.

Now, a team of scientists at the University of Huddersfield is researching how to combat these challenges by using “self-assembled” drugs and although the research is in its very early stages, they’ve already had a breakthrough.

Hyperloop included in $1.2 trillion US infrastructure bill

Hyperloop, the futuristic transportation system first envisioned by Elon Musk, is included in a landmark trillion-dollar infrastructure bill that passed through the US Senate on Tuesday.

The two companies are currently leading the development of a commercial Hyperloop system – Virgin Hyperloop and Hyperloop TT – both with hopes of revolutionizing the way people travel.

The original Hyperloop concept, first laid out by Tesla and SpaceX bosses in a 2012 whitepaper, involves shooting pods filled with people through vacuum tubes at speeds in excess of 1,000 kilometers per hour.

The promises made by this “fifth mode of transportation”, as Mr. Musk calls it, have so far failed to be realized in a commercial operation – a fact in a manifesto published last year by renowned Silicon Valley venture capitalist Marc Andreessen titled Was “It’s time to build”.

A Simple Crystal Could Finally Give Us Large-Scale Quantum Computing, Scientists Say

By lenexweb

Vaccine and drug development, artificial intelligence, transport and logistics, climate science – these are all areas that stand to be transformed by the development of a full-scale quantum computer. And there has been explosive growth in quantum computing investment over the past decade.

Yet current quantum processors are relatively small in scale, with fewer than 100 qubits – the basic building blocks of a quantum computer. Bits are the smallest unit of information in computing, and the term qubits stems from “quantum bits”.

While early quantum processors have been crucial for demonstrating the potential of quantum computing, realizing globally significant applications will likely require processors with upwards of a million qubits.

Our new research tackles a core problem at the heart of scaling up quantum computers: how do we go from controlling just a few qubits, to controlling millions? In research published today in Science Advances, we reveal a new technology that may offer a solution.

For the more than 5 million people in the world who have undergone an upper-limb amputation, prosthetics have come a long way. Beyond traditional mannequin-like appendages, there is a growing number of commercial neuroprosthetics—highly articulated bionic limbs, engineered to sense a user’s residual muscle signals and robotically mimic their intended motions.

But this high-tech dexterity comes at a price. Neuroprosthetics can cost tens of thousands of dollars and are built around metal skeletons, with electrical motors that can be heavy and rigid.

Now engineers at MIT and Shanghai Jiao Tong University have designed a soft, lightweight, and potentially low-cost neuroprosthetic hand. Amputees who tested the artificial limb performed daily activities, such as zipping a suitcase, pouring a carton of juice, and petting a cat, just as well as—and in some cases better than —those with more rigid neuroprosthetics.
