Well, we don’t want that … or do we?

The idea of sentient, lab-created “organoids” raises ethical questions that ripple through science.

Tests could include physical scans, mathematical models, and more.

Scientists say there are reasons it could be necessary to create consciousness … and destroy it.

A thought-provoking new article poses some hugely important scientific questions: Could brain cells initiated and grown in a lab become sentient? What would that look like, and how could scientists test for it? And would a sentient, lab-grown brain “organoid” have some kind of rights?

Honeywell announces its H1 quantum computer with 10 qubits

20ED711E-2FB9-4D02-9CD8-AC7F00790E0F

Honeywell, which was a bit of a surprise entrant into the quantum computing space when it announced its efforts to build the world’s most powerful quantum computer earlier this year, today announced its newest system: the Model H1. The H1 uses trapped-ion technology and features 10 fully connected qubits that allow it to reach a quantum volume of 128 (where quantum volume [QV] is a metric of the overall compute power of a quantum computer, no matter the underlying technology). That’s higher than comparable efforts by IBM, but also well behind the QV 4,000,000 machine IonQ says it was able to achieve with 32 qubits.

The H1 will be available to enterprises through the Azure Quantum platform and the company says that it is partnering with Zapata Computing and Cambridge Quantum Computing on this project.

When it first announced its efforts, Honeywell said that its experience in building control systems allowed it to build an advanced ion trap and more uniform qubits that hence make error correction easier.

 78193C43-5DC8-4AE7-84C6-3F9B46134DF5

From the last week of September onwards, customers of REDI shopping centre may have spotted a small, wheeled robot moving about on its own. Its task is to deliver meals on demand from K-Supermarket to the Majakka high-rise building. Customers can place an order via the building’s Asumi service on their computer or mobile device, and the delivery robot courier will take the products directly to the customer or to the collection point in the building’s shared facilities.

This is an ongoing robot delivery pilot in Kalasatama district in Helsinki implemented by technology company Dimalog in collaboration with Omron and service design agency Muotohiomo. The pilot is coordinated by the city of Helsinki’s innovation company Forum Virium Helsinki with its partners SRV and KONE. SRV is involved regarding the smart living services directed at Majakka residents, while KONE Oyj offers the lift interfaces for the delivery robot to move about in Majakka. Another essential partner is REDI’s K-Supermarket, which has the opportunity to test the robot in its services.

Don’t drop your diet yet, but scientists have discovered how CRISPR can burn fat

8227A0BC-CEC1-4D19-90CB-BD97C18C4E98

A personalized therapy for metabolic conditions that are linked to obesity could involve removing a small amount of a person’s fat, transforming it into an energy-burning variation using CRISPR gene-editing, and then re-implanting it into the body, according to researchers from the University of Massachusetts Medical School.

In tests involving mice, the implanted human fat cells helped lower sugar concentrations in the blood and decrease fat in the liver. When the mice were put on a high-fat diet, the ones that had been implanted with the human beige fat only gained half as much weight as those that had been implanted with regular human fat.

How South Korea’s smart crossings are cutting road deaths

D2DDAEE1-FF04-460C-993C-9CCDC05AF8DF

Crossings in South Korea alert drivers when people are approaching, and warn pedestrians when cars are nearby

The crossing has been preparing for you before you set foot on it. Radar and thermal cameras detect your approach and notify a central control system, which triggers rows of LED warning lights on either side of the walkway to alert approaching drivers to your presence. To keep you alert, the system sounds an alarm and projects a warning image on the ground in front of you. It also sounds an alert on your smartphone. As the driver comes within 30 metres, a blinking electronic sign notifies them of your crossing.

This pedestrian crossing is located in three locations across South Korea, designed by the Korea Institute of Civil Engineering and Building Technology (KICT). It aims to minimise road traffic accidents in response to rising pedestrian casualties, 52.9 per cent of which occur at crossings. Many of these are caused by people crossing while looking at their phones (South Korea has the world’s highest smartphone penetration rate, and some of the highest road fatality and injury rates among developed countries). “So, I came to think of a smart crossing system that recognises the urgency of pedestrian safety on the crosswalk,” Kim Jong-hoon, a senior researcher at KICT says.

These researchers have found a way to turn a common plastic into high-value molecules

 8BE8D0F9-1282-40EA-A055-38E877D024B5

More than 8.3 billion metric tonnes of plastic has been produced in the last six decades.

However, recycling plastic can be difficult as the most common process involves melting and reworking the material.

A new process developed by the University of California can turn polyethylene into useful smaller molecules.

If you thought those flimsy disposable plastic grocery bags represented most of our plastic waste problem, think again. The volume of plastic the world throws away every year could rebuild the Ming Dynasty’s Great Wall of China – about 3,700 miles long.

World’s 1st fully autonomous fruit-picking drones are smarter than humans

4CC4A588-F774-4321-826F-FB10450E2E3A

Israel-based agricultural drone manufacturer Tevel Aerobotics Technologies Ltd. is completing its third round of funding – a $20 million financing round raising its valuation to a cool $45 million

These orders are meant for autonomous drones developed by Tevel Aerobotics which are equipped with a one-meter long mechanical claw. This mechanical extension can be used to pick fruit or for thinning and pruning tasks in orchards.

Tevel claims to use artificial intelligence capabilities on a ground-based mobile unit that acts as the autonomous brain of the drones. The brain lets them identify fruit types, blemishes, and the level of ripeness.

Even though the global fruit-cultivation is expected to grow, the company expects the number of agricultural workers in the field to reduce, projecting a a potential for $3 billion in annual sales to growers in the U.S. and Europe

The wide range of utility that drones offer is sure to make them a popular instrument in the coming years. As a testimony to this, Israel-based agricultural drone manufacturer Tevel Aerobotics Technologies Ltd. is completing its third round of funding – a $20 million financing round raising its valuation to a cool $45 million.

Scientists create artificial, ‘living aneurysm’ outside the human brain in extraordinary first

47FB63CB-E371-497F-95F0-D15EFA3CB581

 For the first time, researchers have 3D printed a ‘living’ model of an aneurysm outside the body, using human brain cells. The breakthrough could one day assist brain surgeons in both training and high-risk decision-making.

An aneurysm occurs when a bulge or bubble develops at a weak point in a given blood vessel, which can take place in the heart or brain. The weakened wall can eventually rupture, with catastrophic and life-threatening consequences for the patient.

Given the highly sensitive and delicate areas in which aneurysms take place, they are often extremely difficult to both find and treat.

As a potential solution, researchers at the Lawrence Livermore National Laboratory (LLNL), including scientists from Duke University and Texas A&M, have created an external, artificial replica which mimics the particular environment in which aneurysms occur.

A team of researchers is creating mobile robots for military applications that can determine, with or without human intervention, whether wheels or legs are more suitable to travel across terrains. The Defense Advanced Research Projects Agency (DARPA) has partnered with Kiju Lee at Texas A&M University to enhance these robots’ ability to self-sufficiently travel through urban military environments.

The DARPA OFFensive Swarm-Enabled Tactics (OFFSET) program awarded Lee, associate professor in the Department of Engineering Technology and Industrial Distribution and the J. Mike Walker ’66 Department of Mechanical Engineering, and a team of graduate students another contract after her prior successful accomplishments on developing a mixed-reality swarm simulator with embedded consensus-based decision making for adaptive human-swarm teaming as part of the OFFSET Sprint-3. This project was showcased at OFFSET’s third field experiment (FX3) with other participating teams.

Researchers 3D-printed a cell-sized tugboat

 A8A37081-6319-405E-9D04-FFBDB8BC5A2D

The aim was to see how microorganisms like sperm or bacteria swim.

 Physicists at Leiden University in the Netherlands have 3D printed what could be the world’s smallest boat, a test object known as Benchy (via Gizmodo). At 30 microns long, it’s a third smaller than the thickness of a human hair and about six times larger than a bacteria cell. It’s not only small but surprisingly detailed, with an open cockpit that features some tricky geometry. The goal is to understand how “microswimmers” like bacteria and sperm move through liquids.

Reimagining higher education in the United States

 F5690555-6BE7-442D-A227-60ECEF04F564

As education leaders consider their options in the age of the COVID-19 crisis, they must rethink the conventional wisdom.

Higher education in the United States is at an inflection point. The core mission of the university—instruction, research, and service—has not changed. Nor has the need for advanced education to prepare individuals for a fulfilling life and to drive the knowledge economy. For individuals, the economic benefit of earning a college degree remains clear. College graduates are on average wealthier, healthier, and happier over a lifetime.1

Even before the COVID-19 crisis, however, the higher-education sector faced significant challenges. Consider student completion: only 60 percent of all those who started college actually earned a degree within six years in 2017 (the latest year for which data is available). The figures are even worse for Black (39.9 percent) and Hispanic (54.4 percent) students. Other troubling disparities persist. In student enrollment, for example, 69 percent of white high-school graduates enroll in college, compared with 59 percent of Black high-schoolers and 61 percent of Hispanics. Furthermore, the level of student debt is rising, while repayment rates plummet, creating a potentially unsustainable burden for many students.

The pandemic is intensifying these challenges and creating new ones. Students and their families are struggling with the impact of campus shutdowns and questioning whether it is worth it to pay for an on-campus experience when much of the instruction is being done remotely. Under these circumstances, the risk of outcome inequities—from completion to employment to lifetime earnings—could worsen. For example, evidence suggests that lower-income students are 55 percent more likely than their higher-income peers to delay graduation2 due to the COVID-19 crisis. Underpinning all of these challenges is a business model at its breaking point, as institutions face falling revenues and rising health-and-safety costs.

In short, the coronavirus has confirmed the case for fast and fundamental change. It has also demonstrated that change is possible. When the pandemic hit, many US colleges and universities moved quickly to remote learning and other delivery models, launched affordability initiatives, and found creative ways to support their students. Now is the time to build on these lessons to reimagine the next five to ten years and beyond.
