Putting that soda bottle or takeout container into the recycling bin is far from a guarantee it will be turned into something new. Scientists at Rice University are trying to address this problem by making the process profitable.

The amount of waste produced globally has doubled over the past two decades—and plastic production is expected to triple by 2050—with most of it ending up in landfills, incinerated or otherwise mismanaged, according to the Organization for Economic Cooperation and Development. Some estimates suggest only 5% is actually being recycled.

“Waste plastic is rarely recycled because it costs a lot of money to do all the washing, sorting and melting down of the plastics to turn it into a material that can be used by a factory,” said Kevin Wyss, a Rice graduate student and lead author on a study published in Advanced Materials that describes how he and colleagues in the lab of chemist James Tour used their flash Joule heating technique to turn plastic into valuable carbon nanotubes and hybrid nanomaterials.

NASA’s mission has always been dedicated to promoting science, technology, aeronautics, and space exploration to improve education, economic vitality, environmental stewardship, innovation, and most importantly knowledge.

For the past week, the space agency has achieved a lot in exploring outer space and shared important insights for further research. From naming a mountain on the Moon, watching and helping from space, and gathering rock samples, here are a few stories that made it to the list:

UN hopes to complete revisions to the Law of the Sea governing the protection of marine biodiversity.


In 2017, the members of the General Assembly of the United Nations convened to review the existing Convention on the Law of Sea with the idea to look at providing protection for marine biodiversity and ocean waters beyond marine national government boundaries and exclusive economic zones. Subsequently, there have been meetings at the United Nations to work through outstanding issues with the last in August 2022. A revised Intergovernmental conference is now underway and expected to last two weeks to complete a new High Seas Treaty.

The world’s oceans and seas cover more than 70% of the planet’s surface. The ocean contains 1.35 billion cubic kilometres (324 million cubic miles) of water representing 97% of all the water on the planet. The ocean is where life on Earth first came from and is what makes the continuation of life on this planet possible.

A portion of the ocean lies within the jurisdictions of nation-states. In these locales, countries establish the rules regarding the exploitation of ocean resources from below the seabed, through the entire vertical water column, to the surface as above. But beyond these jurisdictions is a collective commons where national laws bear no weight. That, however, hasn’t stopped countries, fishers, fossil fuel companies and even mining ventures from staking claims. In this arena, a mere 1.2% is currently protected from those looking to exploit what the ocean has to give.

Researchers at the University of North Carolina at Chapel Hill Department of Chemistry have engineered silicon nanowires that can convert sunlight into electricity by splitting water into oxygen and hydrogen gas, a greener alternative to fossil fuels.

Fifty years ago, scientists first demonstrated that liquid water can be split into oxygen and using electricity produced by illuminating a semiconductor electrode. Although hydrogen generated using is a promising form of clean energy, low efficiencies and have hindered the introduction of commercial solar-powered hydrogen plants.

An economic feasibility analysis suggests that using a slurry of electrodes made from nanoparticles instead of a rigid solar panel design could substantially lower costs, making solar-produced hydrogen competitive with fossil fuels. However, most existing particle-based light-activated catalysts, also referred to as photocatalysts, can absorb only , limiting their energy-conversion efficiency under solar illumination.

‘Infinite Resources’

Producing nearly infinite clean energy in the arctic to address the world’s energy, water and climate problems.

A conversation with Jeff Krehmer on how to solve many the world’s problem based on his upcoming book ‘Infinite Resources.

Autonomous aircraft have long been thought of as having the most potential, though not in the realm of glitzy people-carrying drones so much as the more sedate world of cargo. It’s here where the economic savings could be most significant. Large, long-range drones built specifically for cargo have the potential to be faster, cheaper and produce fewer CO2 emissions than conventional aircraft, enabling same-day shipping over very long distances. In fact, the “flying delivering van” is considered the holy grail by many cargo operators.

In this space there are a number of companies operating, and these include: ElroyAir (California, raised $56 million), hybrid electric, VTOL, so so therefore short range; Natilus (California, funding undisclosed) uses a blended wing body, and is a large, longer-term project entailing probably quite high costs in certification and production; and Beta (Vermont, $886 million raised), which is an electric VTOL.

Into this space, out of Bulgaria (but HQ’d in London), comes Dronamics. The startup has already attained a license to operate in Europe, and plans to run a “cargo drone airline” using drones built specifically for the purpose. Dronamics claims its flagship “Black Swan” model will be able to carry 350 kg (770 lb) at a distance of up to 2,500 km (1,550 miles) faster, cheaper and with less emissions than currently available options.

A second problem is the risk of technological job loss. This is not a new worry; people have been complaining about it since the loom, and the arguments surrounding it have become stylized: critics are Luddites who hate progress. Whither the chandlers, the lamplighters, the hansom cabbies? When technology closes one door, it opens another, and the flow of human energy and talent is simply redirected. As Joseph Schumpeter famously said, it is all just part of the creative destruction of capitalism. Even the looming prospect of self-driving trucks putting 3.5 million US truck drivers out of a job is business as usual. Unemployed truckers can just learn to code instead, right?

Those familiar replies make sense only if there are always things left for people to do, jobs that can’t be automated or done by computers. Now AI is coming for the knowledge economy as well, and the domain of humans-only jobs is dwindling absolutely, not merely morphing into something new. The truckers can learn to code, and when AI takes that over, coders can… do something or other. On the other hand, while technological unemployment may be long-term, its problematicity might be short-term. If our AI future is genuinely as unpredictable and as revolutionary as I suspect, then even the sort of economic system we will have in that future is unknown.

A third problem is the threat of student dishonesty. During a conversation about GPT-3, a math professor told me “welcome to my world.” Mathematicians have long fought a losing battle against tools like Photomath, which allows students to snap a photo of their homework and then instantly solves it for them, showing all the needed steps. Now AI has come for the humanities and indeed for everyone. I have seen many university faculty insist that AI surely could not respond to their hyper-specific writing prompts, or assert that at best an AI could only write a barely passing paper, or appeal to this or that software that claims to spot AI products. Other researchers are trying to develop encrypted watermarks to identify AI output. All of this desperate optimism smacks of nothing more than the first stage of grief: denial.

A couple minutes of your time for a little optimism.


Dr David Sinclair talks about no matter all the push backs and criticizes, he believes reverse aging therapy for human will be succeeded in this short clip.

David Sinclair is a professor in the Department of Genetics and co-director of the Paul F. Glenn Center for the Biology of Aging at Harvard Medical School, where he and his colleagues study sirtuins—protein-modifying enzymes that respond to changing NAD+ levels and to caloric restriction—as well as chromatin, energy metabolism, mitochondria, learning and memory, neurodegeneration, cancer, and cellular reprogramming.

Dr David Sinclair has suggested that aging is a disease—and that we may soon have the tools to put it into remission—and he has called for greater international attention to the social, economic and political and benefits of a world in which billions of people can live much longer and much healthier lives.

Dr David Sinclair is the co-founder of several biotechnology companies (Life Biosciences, Sirtris, Genocea, Cohbar, MetroBiotech, ArcBio, Liberty Biosecurity) and is on the boards of several others.

In collaboration with the UC San Diego Center for Integrative Nutrition, the Berry Good Food Foundation convenes a panel of experts to discuss the rise of comprehensive medicine and nutritional healing to treat chronic disease and maintain general well-being. [6/2018] [Show ID: 33486]
