The rise of the 3-parent family

829F81F9-872E-4FE2-96C7-66F9B17FEB4F

The typical path to parenthood didn’t work for David Jay, a founder of the asexual movement. So he designed his own household—and is trying to show others what is possible.

David Jay is the oldest of 12 cousins on one side of his family and the third-oldest of 24 cousins on the other. As a kid, family to Jay meant having a lot of people around, a feeling of community, and crucially, a sense of permanence, that these people would always be in his life. Later, as an adult living in collective housing, he could access the feeling of family with those around him, but the permanence was gone. His roommates started finding romantic partners, having children, and dispersing. Jay had always wanted his own family with kids—and had known, for almost as long, that he wouldn’t be able to build one the usual way.

Jay is the founder of the Asexual Visibility and Education Network and one of the most prominent people in the asexual movement. (Asexual people, or aces, don’t experience sexual attraction, though many do have sex and form romantic relationships.) After starting AVEN as a freshman at Wesleyan University in 2001, Jay spent years explaining asexuality to the public, speaking at events and talking to the press. As he grew older, the questions on his mind moved beyond identity and attraction to issues of parenting and family life.

The problem for Jay was never how babies are made, and fostering and adoption were options. The problem was that he wanted kids and also wanted a co-parent to help him raise kids, but wasn’t interested in romantic partnership. Before exploring single parenthood, he was curious whether there might be another way to form the family he wanted.

Water on Mars: discovery of three buried lakes intrigues scientists

312879B6-627E-4D62-8666-9C72EA93F1EF

Researchers have detected a group of lakes hidden under the red planet’s icy surface.

Scientists have long thought that there could be water trapped beneath the surface of Mars.

Two years ago, planetary scientists reported the discovery of a large saltwater lake under the ice at Mars’s south pole, a finding that was met with excitement and some scepticism. Now, researchers have confirmed the presence of that lake — and found three more.

The discovery, reported on 28 September in Nature Astronomy1, was made using radar data from the European Space Agency’s Mars-orbiting spacecraft, called Mars Express. It follows the detection of a single subsurface lake in the same region in 2018 — which, if confirmed, would be the first body of liquid water ever detected on the red planet and a possible habitat for life. But that finding was based on just 29 observations made from 2012 to 2015, and many researchers said they needed more evidence to support the claim. The latest study used a broader data set comprising 134 observations from 2012 to 2019.

9 soft skills every employee will need in the age of Artificial Intelligence (AI)

933DD2AB-2D51-49A4-97A2-00DFA224BC07

Technical skills and data literacy are obviously important in this age of AI, big data, and automation. But that doesn’t mean we should ignore the human side of work – skills in areas that robots can’t do so well. I believe these softer skills will become even more critical for success as the nature of work evolves, and as machines take on more of the easily automated aspects of work. In other words, the work of humans is going to become altogether more, well, human.

With this in mind, what skills should employees be looking to cultivate going forward? Here are nine soft skills that I think are going to become even more precious to employers in the future.

Self-driving cars will hit the Indianapolis Motor Speedway in a landmark A.I. race

52075E8D-4D3E-46B5-BF84-25BE28488BB2

Take a look at the ‘Road of the Future’

Next year, a squad of souped-up Dallara race cars will reach speeds of up to 200 miles per hour as they zoom around the legendary Indianapolis Motor Speedway to discover whether a computer could be the next Mario Andretti.

The planned Indy Autonomous Challenge—taking place in October 2021 in Indianapolis—is intended for 31 university computer science and engineering teams to push the limits of current self-driving car technology. There will be no human racers sitting inside the cramped cockpits of the Dallara IL-15 race cars. Instead, onboard computer systems will take their place, outfitted with deep-learning software enabling the vehicles to drive themselves.

In order to win, a team’s autonomous car must be able to complete 20 laps—which equates to a little less than 50 miles in distance—and cross the finish line first in 25 minutes or less. At stake is a $1 million prize, with second- and third-place winners receiving a $250,000 and $50,000 award, respectively.

 Machine learning takes on synthetic biology: algorithms can bioengineer cells for you.

If you’ve eaten vegan burgers that taste like meat or used synthetic collagen in your beauty routine—both products that are “grown” in the lab—then you’ve benefited from synthetic biology. It’s a field rife with potential, as it allows scientists to design biological systems to specification, such as engineering a microbe to produce a cancer-fighting agent. Yet conventional methods of bioengineering are slow and laborious, with trial and error being the main approach.

Now scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new tool that adapts machine learning algorithms to the needs of synthetic biology to guide development systematically. The innovation means scientists will not have to spend years developing a meticulous understanding of each part of a cell and what it does in order to manipulate it; instead, with a limited set of training data, the algorithms are able to predict how changes in a cell’s DNA or biochemistry will affect its behavior, then make recommendations for the next engineering cycle along with probabilistic predictions for attaining the desired goal.

World’s first hydrogen-electric passenger flight brings us ‘one step closer’ to zero -emissions air travel

‘The size of this commercially available aircraft shows that paying passengers could be boarding a truly zero-emission flight very soon,’ says ZeroAvia CEO

The world’s first hydrogen-electric passenger flight was successfully completed on 24 September, potentially bringing the aviation industry a step closer to zero-emissions air travel.

The six-seater aircraft did a taxi, takeoff, full pattern circuit and landing at an airfield in Cranfield, England.

ZeroAvia, the company behind the plane, said it was the first ever hydrogen fuel cell-powered flight using a commercial-grade aircraft.

The brand’s retrofitted Piper M-class is now the largest hydrogen-powered aircraft in the world.

Schematic diagram of construction of the anisotropic cartilage scaffold and study design. (B) A computer-aided design (CAD) model was used to design the four-layer gradient PCL scaffolding structure to offer BMS for anisotropic chondrogenic differentiation and nutrient supply in deep layers (left). Gradient anisotropic cartilage scaffold was constructed by one-step 3D bioprinting gradient polymeric scaffolding structure and dual protein-releasing composite hydrogels with bioinks encapsulating BMSCs with BMP4 or TGFβ3 μS as BCS for chondrogenesis (middle). The anisotropic cartilage construct provides structural support and sustained release of BMSCs and differentiative proteins for biomimetic regeneration of the anisotropic articular cartilage when transplanted in the animal model (right). Different components in the diagram are depicted at the bottom. HA, hyaluronic acid.

 

Cartilage injury is a common cause of joint dysfunction and existing joint prostheses cannot remodel with host joint tissue. However, it is challenging to develop large-scale biomimetic anisotropic constructs that structurally mimic native cartilage. In a new report on Science Advances, Ye Sun and a team of scientists in orthopedics, translational research and polymer science in China, detailed anisotropic cartilage regeneration using three-dimensional (3-D) bioprinting dual-factor releasing gradient-structured constructs. The team used the dual-growth-factor releasing mesenchymal stem cell (MSC)-laden hydrogels for chondrogenic differentiation (cartilage development). The 3-D bioprinted cartilage constructs showed whole-layer integrity, lubrication of superficial layers and nutrient supply into deeper layers. The scientists tested the cartilage tissue in the lab and in animal models to show tissue maturation and organization for translation to humans after sufficient experimental studies. The one-step, 3-D printed dual-factor releasing gradient-structured cartilage constructs can assist regeneration of MSC- and 3-D bioprinted therapy for injured or degenerative joints.

Thin and ultra-fast photodetector sees the full spectrum

F3F6924D-F12D-46E6-A541-36F194FB96B3

Artist’s impression of the photodetector device created by RMIT University researchers.

 Researchers have developed the world’s first photodetector that can see all shades of light, in a prototype device that radically shrinks one of the most fundamental elements of modern technology.

Photodetectors work by converting information carried by light into an electrical signal and are used in a wide range of technologies, from gaming consoles to fibre optic communication, medical imaging and motion detectors. Currently photodetectors are unable to sense more than one color in the one device.

This means they have remained bigger and slower than other technologies, like the silicon chip, that they integrate with.

The new hyper-efficient broadband photodetector developed by researchers at RMIT University is at least 1,000 times thinner than the smallest commercially available photodetector device.

Transforming homes into power stations – how Sweden is disrupting energy production

C4BF9D81-567B-414C-AD54-9B3CA3D9C57D

  • 54% of Sweden’s power comes from renewables and this energy is increasingly local.
  • Smart grids are switching Swedish homes from energy consumers to power-making ‘prosumers.’
  • Local ‘district heating’ plants use excess heat to warm the majority of Swedish homes.
  • Sweden tops the World Economic Forum’s Energy Transitions Index

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.

As well as targeting 100% renewable electricity production by 2040, the country is transforming homes into highly efficient ‘prosumers’ – buildings which both produce and consume the vast majority of their own energy.

Top 10 digital transformation trends for 2021

3DF3A010-46C2-4E69-893D-CCAD0D69AED2

No one could have predicted where 2020 would take us: The last six months alone have produced more digital transformation than the last decade, with every transformation effort already underway finding itself accelerated, and at scale. While many of my digital transformation predictions from a year ago benefited from this shift, others were displaced by more urgent needs, like 24/7 secure and reliable connectivity. What does this mean for 2021? Will core technologies like AI and data analytics still dominate headlines, or will we see newer, previously emerging technologies take the lead? Only time will tell, but here are my top ten digital transformation predictions for 2021.

Pandemic accelerated cord cutting, making 2020 the worst-ever year for pay TV

 couple watching tv in their home

The pandemic has accelerated adoption of a number of technologies, from online grocery to multiplatform gaming to streaming services and more. But one industry that has not benefited is traditional pay TV. According to new research from eMarketer, the cable, satellite and telecom TV industry is on track to lose the most subscribers ever. This year, over 6 million U.S. households will cut the cord with pay TV, bringing the total number of cord-cutter households to 31.2 million.

The firm says that by 2024, the number will grow even further, reaching 46.6 million total cord-cutter households, or more than a third of all U.S. households that no longer have pay TV.

Despite these significant declines, there are still more households that have a pay TV subscription than those that do not. Today, there are 77.6 million U.S. households that have cable, satellite or telecom TV packages. But that number has declined 7.5% year-over-year — its biggest-ever drop. The figure is also down from pay TV’s peak in 2014, the analysts said.
