A UCF research team with collaborators at Virginia Tech have developed a new “green” approach to making ammonia that may help make feeding the rising world population more sustainable.

“This new approach can facilitate ammonia production using renewable energy, such as electricity generated from solar or wind,” said physics Assistant Professor Xiaofeng Feng. “Basically, this new approach can help advance a sustainable development of our human society.”

Ammonia, a compound of nitrogen and hydrogen, is essential to all life on the planet and is a vital ingredient in most fertilizers used for food production. Since World War I, the ammonia in fertilizer has been primarily produced using the Haber-Bosch method, which is energy and fossil-fuel intensive. There have been substantial obstacles to improving the process, until now.

If someone tells you to go suck an egg, you might want to think twice about it if you live on the east coast. The United States Centers for Disease Control and Prevention announced last month that a Salmonella outbreak affecting hundreds of millions of eggs had been traced back to a farm in Hyde County, North Carolina. Public health officials have traced consumers’ illnesses in nine different states to the outbreak. Last week, the CDC released a map showing the outbreak’s spread.

Rose Acre Farms, the company responsible for the outbreak, distributes eggs all over the US, to both grocery stores and restaurants. As a result of contamination on the North Carolina farm, over 206 million eggs were exposed to Salmonella braenderup, a bacteria that causes severe diarrhea. The outbreak began in mid-April and appears to be slowing down, but in a multi-state outbreak like this, officials at the CDC may not hear about people getting sick right away. Therefore, the data on the case continues to evolve as reports roll in. The most recent numbers count 35 illnesses, 11 hospitalizations, and no deaths. Here’s a map of the outbreak’s current extent:

Australia’s recycling crisis needs us to look into waste management options beyond just recycling and landfilling. Some of our waste, like paper or organic matter, can be composted. Some, like glass, metal and rigid plastics, can be recycled. But we have no immediate solution for non-recyclable plastic waste except landfill.

At a meeting last month, federal and state environment ministers endorsed an ambitious target to make all Australian packaging recyclable, compostable or reusable by 2025. But the ministers also showed support for processes to turn our waste into energy, although they did not specifically discuss plastic waste as an energy source.

The 100% goal could easily be achieved if all packaging were made of paper or wood-based materials. But realistically, plastic will continue to dominate our packaging, especially for food, because it is moisture-proof, airtight, and hygienic.

A team of researchers at the University of Texas has found NAD+ synthesis and consumption integrate glucose metabolism and adipogenic transcription during adipocyte differentiation. In their paper published in the journal Science, the group describes their research into how glucose is converted into fat in the body and what they found. Sophie Trefely and Kathryn Wellen with the University of Pennsylvania and Drexel University, respectively, offer a Perspective piece on the work done by the team in Texas in the same journal issue.

As obesity rates continue to climb around the globe, scientists continue to explore why it is happening. In addition to studying the psychological aspects involved, scientists would also like to better understand why eating too much makes people gain weight. In this new effort, the researchers looked more closely into why consuming too much glucose causes the body to produce fat.

Prior research has shown that nicotinamide adenine dinucleotide (NAD) is an important molecule that plays a role in a wide variety of physiological and pathological processes. Its oxidized form, NAD+, has also been found to act as a cofactor in metabolic pathways, and more importantly, perhaps, is consumed by various enzymes. Once consumed, NAD+ is broken down into nicotinamides and ADP-ribose. This, the researchers note, means that NAD+ must be resynthesized for normal cellular function to continue. They further note that some prior research has suggested that lower-than-normal levels of NAD+ can alter metabolism, leading in some cases to higher disease susceptibility.

In the heart of San Francisco’s Mission Bay neighborhood, which not long ago was dirt lots and warehouses, Emily Leproust is cooking up what she — and $209 million worth of investor cash — believes is the future of DNA production.

Leproust is CEO of Twist Bioscience, a 5-year-old biotech company striving to make the production of synthetic DNA — which is used in fragrances, genetically modified foods and pharmaceutical drugs — cheaper, faster and smaller.

The same lab-manufactured DNA, Leproust hopes, could also transform the way data, from music to medical records, is stored.

Drones that monitor crops, control mosquito populations and deliver defibrillators are to be tested in US airspace.

Ten commercial drone projects have been selected to try out new ways for unmanned aircraft to be integrated into the skies.

They include Zipline, which currently offers a blood-delivery service in Rwanda, and Apple.

These vegetables grew without any soil or light in subzero Antarctica. #MadeInAntarctica

A Purdue University-affiliated startup that seeks to redefine “farm-to-table” when it comes to garden vegetables by delivering its first orders of an appliance that fits under a kitchen counter and grows produce year-round.

Heliponix LLC, founded by two Purdue University graduates, has begun taking orders on its GroPod, a dishwasher-sized device its creators believe will disrupt the landscape of how food is produced in the face of looming worldwide food shortages and increasing concerns about chemical runoff polluting water sources, rampant food waste and water supplies diminishing on a global scale.

“It’s great for consumers and for the environment,” said Scott Massey, CEO of Heliponix.
