Researchers develop greener alternative to fossil fuels

Posted by in categories: economics, nanotechnology, particle physics, solar power, sustainability

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.

Autonomous cargo drone airline Dronamics reveals it’s raised $40M, pre-Series A

Posted by in categories: drones, economics, robotics/AI

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.

AI and the Transformation of the Human Spirit

Posted by in categories: business, economics, employment, encryption, mathematics, robotics/AI, transportation

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.

Honeybee venom and melittin suppress growth factor receptor activation in HER2-enriched and triple-negative breast cancer

Posted by in categories: biotech/medical, economics

Apitherapy is an emerging field with the potential to impact the economic aspects of cancer research globally, particularly in under-resourced communities. To date, however, studies are yet to fully investigate the molecular mechanism of action of honeybee venom and melittin, and their consequent optimum usage in the oncology arena is yet to be comprehensively investigated, particularly for the treatment of breast cancer, the most commonly occurring cancer in women worldwide2. TNBCs and HER2-enriched tumors are highly aggressive breast cancer subtypes. TNBC is associated with the highest mortality and, despite frequent EGFR expression, commonly displays resistance to anti-EGFR therapies with high dependence on PI3K/Akt signaling for proliferation, survival, and chemotherapy resistance34.

Anti-HER2 therapies have substantially improved long-term survival in early-stage HER2-positive cancers, but the majority of late-stage patients eventually develop resistance and succumb to the disease33,35,36. Not only did we demonstrate selectivity of honeybee venom and melittin for malignant cells, but we also revealed higher potencies for these aggressive types of breast cancer.

Here, we show that honeybee venom and melittin suppress the ligand-induced phosphorylation of EGFR and HER2, dynamically modulating downstream signaling pathways in breast cancer cells. We propose that melittin directly or indirectly inhibits RTK dimerization. Melittin may also enter the cell to directly or indirectly modulate downstream signaling pathways25,60. Previous work has shown that melittin can be targeted to HER2-overexpressing cell lines using immunoliposomes bearing trastuzumab61. Here, we demonstrate that melittin alone selectively targets HER2-and EGFR-overexpressing breast cancer cells. Interestingly, melittin was more potently toxic to breast cancer cells compared to honeybee venom, warranting further investigation.
