Scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have made a surprising discovery that could help explain our risk for developing chronic diseases or cancers as we get older, and how our food decomposes over time.

What’s more, their findings, which were reported recently in the Proceedings of the National Academy of Sciences (PNAS), point to an unexpected link between the ozone chemistry in our atmosphere and our cells’ hardwired ability to ward off disease.

“The beauty of nature is that it often decides to use similar chemistries throughout a system, but we never thought that we would find a common link between atmospheric chemistry, and the chemistry of our bodies and food,” said Kevin Wilson, the deputy director of Berkeley Lab’s Chemical Sciences Division who led the study. “Our study is the first to explore another chemical pathway that might affect how well the cells in our bodies — and even our food — can respond to oxidative stress, such as pollution, over time.”

That bees are downright awesome is not up for debate. After all, they pollinate about a third of all the crops that we consume and help to support ecosystems worldwide. Yet the bees are in trouble, with a phenomenon known as colony collapse disorder (CCD) causing an alarming drop in numbers. Fortunately, a solution may be on the horizon in the form of genetically modified bacteria.

One thing that is a topic of great debate is the cause of CCD. Some studies point the finger at a particular class of pesticides called neonicotinoids, although many within the scientific community agree that multiple factors are probably at play.

What we do know is that CCD first became an issue once the Varroa mite became widespread, largely thanks to a global trade in European honeybees that brought them into contact with Asian parasites. At first, it was assumed that the mites were simply killing bees by sucking on their blood, although it later transpired that they also carried the lethal deformed wing virus (DWV), transmitting it into the bloodstream of the bees they feasted on.

Life on Earth is dependent on photosynthesizing plants and algae for food, yet land plants did not evolve until about 450 million years ago, Tang said. “The new fossil suggests that green seaweeds were important players in the ocean long before their descendants, land plants, took control,” he said.

These fossils came from an ancient ocean, but there is still a debate about where green algae originated. “Not everyone agrees with us; some scientists think that green plants started in rivers and lakes, and then conquered the ocean and land later,” Xiao said in a statement.

Moreover, green algae isn’t the oldest algae on record. “There is strong fossil evidence that red algae existed over a billion years ago, and we know the red and green algae diverged from a common ancestor,” Gibson told Live Science in an email. “So, although this doesn’t fundamentally change the way I’ll think about the evolution of life, the discovery of this green algal fossil helps fill an important gap and strengthens an emerging timeline for the evolution of early, complex life.”

The Neolithic revolution, and the corresponding transition to agricultural and pastoralist lifestyles, represents one of the greatest cultural shifts in human history, and it has long been hypothesized that this might have also provided the opportunity for the emergence of human-adapted diseases. A new study published in Nature Ecology & Evolution led by Felix M. Key, Alexander Herbig, and Johannes Krause of the Max Planck Institute for the Science of Human History studied human remains excavated across Western Eurasia and reconstructed eight ancient Salmonella enterica genomes—all part of a related group within the much larger diversity of modern S. enterica. These results illuminate what was likely a serious health concern in the past and reveal how this bacterial pathogen evolved over a period of 6,500 years.

Searching for ancient pathogens

Most pathogens do not cause any lasting impact on the skeleton, which can make identifying affected archaeological remains difficult for scientists. In order to identify past diseases and reconstruct their histories, researchers have turned to genetic techniques. Using a newly developed bacterial screening pipeline called HOPS, Key and colleagues were able to overcome many of the challenges of finding ancient pathogens in metagenomics data.

Plastic has become ubiquitous in our home and work lives over the past 50 years. It is pliable, durable, easy to make, and hard to break. Plastic may be convenient and useful, but it also won’t break down naturally, which makes it a long-lasting pollutant. A recent study published in Science Advances found that humans have produced 8,300 million metric tons of plastic to date, which is 25,000 times the weight of the Empire State Building. Seventy nine percent of that has ended up in landfills or the ocean. If we continue making plastic at our current rate, that figure will reach 12,000 metric tons by the year 2050. Plastic pollutants are showing up in drinking water all over the world as well as in food products, like beer. We have a serious problem.

Humans are “addicted” to plastic, says Gavin McIntyre, chief scientist and co-founder of Ecovative, a company aiming to reduce our dependence on plastic and other toxic or non-decomposable materials by making biodegradable alternatives. For several years, Ecovative has been manufacturing eco-friendly packaging supplies, and has just received a grant from the Environmental Protection Agency to further develop its new product, mResin, an alternative to the harmful adhesives found in most paneling and insulation.

Ecovative products, unlike most synthetic plastics that are made from crude oil, are grown from mycelium—networks of fungal or mushroom roots. In nature, fungi break down waste, such as old leaves, dead plants, and pieces of wood, and use it to propagate. Ecovative harnesses this natural process and grows the mycelium into various shapes and structures, from pieces of furniture to packaging materials like MycoFoam, its trademarked Styrofoam substitute.

Global shipping has dropped off, and exporters are warning that refrigerated container (reefer) shortages pose major problems for food trade. Soil is even wetter than last year in US Midwest, presaging a difficult — and potentially catastrophic — 2020 season. UK is under water. China is shutdown. Australia reported record low crops. Grow food. Store it. Prepare for a limited collapse of our food system.

Europe’s first fast food delivery service by drone will start in south Dublin in a matter of weeks, according to Manna Aero founder, Bobby Healy.

Speaking today on Independent.ie’s technology podcast, The Big Tech Show, Mr Healy said that the public service will be launched in a south Dublin suburb with 30,000 people in March. He said that the three-minute service will deliver food from several chains.

“Camile Thai is a partner on the food side,” he said. “Next Tuesday, we will formally announce the name of a major online food player that everybody knows.”
