Engineering nanoparticles can be extremely beneficial for many applications. However, this article discusses in what ways nanotechnology needs to be regulated due to the environmental impacts it can have in areas such as agriculture.

A university in Singapore has conducted one of the first practical flights of a solar-powered quadcopter drone.

The prototype has flown as high as 10 meters (about 33 feet) in test flights using solar power with no battery or other energy storage on board, according to the National University of Singapore (NUS), which announced that an engineering team had conducted the test flight.

“Rotary winged aircraft are significantly less efficient at generating lift compared to their fixed wing counterparts [so] a viable 100 per cent solar rotary aircraft that can take-off and land vertically remains a major engineering challenge to date,” the university said in a statement.

In late July, Bruce Jakosky and Christopher Edwards published a paper titled “Inventory of CO₂ available for terraforming Mars,” which was sponsored by NASA. The paper analyzed the amount of volatiles, primarily carbon dioxide (CO₂), on or in Mars currently, and concluded reasonably that there are not enough volatiles available on Mars to terraform it sufficiently for a person to not need a pressure suit. Jakosky is the principal investigator for MAVEN, the NASA Mars orbiter studying the planet’s atmosphere. He and his co-author wrote what is technically an accurate paper, in spite of what was an existing mild controversy over the amount of some volatiles in the soil and regolith of Mars.

Today, we would like to share with you the talk given by Kelsey Moody, CEO of Biotech Company Ichor, at the recent Ending Age-Related Diseases: Investment Prospects & Advances in Research conference in New York City. In this talk, Kelsey discusses Ichor’s protein engineering platform, how Ichor has used it, and Ichor’s plans for using it to discover new classes of drugs for age-related diseases.

Kelsey is a process-oriented biotechnology executive who has specialized in the study of aging and aging mechanisms for over a decade. Since 2013, he has successfully built Ichor Therapeutics from a living room start-up into a premier, vertically integrated contract research organization that focuses on preclinical research services for aging pathways. Proceeds from this work are used to self-fund R&D initiatives that constitute Ichor’s portfolio companies in enzyme therapy (Lysoclear, Inc.), small molecule drug discovery (Antoxerene, Inc.), and protein engineering (RecombiPure, Inc.) Kelsey has received graduate-level training in medicine, business, and laboratory research.

Now that we are starting to see the arrival of actual therapies aimed at targeting the processes of aging directly in order to prevent age-related diseases, it has become easier to separate two very distinct groups.

The first group consists of the snake oil salesmen peddling unproven supplements and therapies to whoever is foolish enough to buy and take things on faith without using the scientific method. The hucksters have long been a plague on our field, preying on the gullible and tainting legitimate science with their charlatanry and nonsense. One example is the “biotech company” that makes bold claims yet never delivers on those claims in practice, offering data based on poorly designed experiments and tiny cohorts that are statistically irrelevant; another example is the supplement peddler selling expensive supplement blends with flashy names, which, on inspection, turn out to be commonly available herbs and minerals mixed and sold at a high markup. These sorts of people have plagued our community and given the field a reputation of snake oil.

The second group are the credible scientists, researchers, and companies who have been working on therapies for years and sometimes more than a decade. Many of these therapies are following the damage repair approach advocated by Dr. Aubrey de Grey of the SENS Research Foundation over a decade ago. The basic idea is to take an engineering approach to the damage that aging does to the body and to periodically repair that damage in order to keep its level below that which causes pathology. These therapies are now starting to arrive, with some already in human trials right now, and this marks a milestone in our field: the credible science has finally outstripped the snake oil, and the focus can move from pseudoscience to real, evidence-based science.

It may seem off-putting to some, but human waste is full of nutrients that can be recycled into valuable products that could promote agricultural sustainability and better economic independence for some developing countries.

Cities produce and must manage huge quantities of wastewater. Researchers at the University of Illinois at Urbana-Champaign have developed a model to clarify what parts of the world may benefit most from re-circulation of human-waste-derived nitrogen, potassium and phosphorus from cities and back into farm fields. They report their findings in the journal Nature Sustainability.

“We grow our crops in the field, apply nutrient-rich fertilizers, eat the crops, excrete all of the nitrogen, phosphorus and potassium and then those nutrients end up at the wastewater treatment plant,” said Jeremy Guest, a civil and environmental engineering professor and study co-author. “It is a very linear, one-directional flow of resources. Engineering a more circular nutrient cycle would create opportunities that could benefit the environment, economy and agriculture.”

Historically, water managers throughout the thirsty state of California have relied on hydrology and water engineering—both technical necessities—as well as existing drought and flood patterns to plan for future water needs.

Now, climate change is projected to shift water supplies as winters become warmer, spring snowmelt arrives earlier, and extreme weather-related events increase. Some water utilities have started to consider these risks in their management, but many do not. Lack of climate change adaptation among water utilities can put water supplies and the people dependent on them at risk, especially in marginalized communities, a new University of California, Davis, paper suggests.

The paper, which analyzes various approaches to climate science by drinking water utility managers in California, was presented along with new research at the American Sociology Association Conference in Philadelphia on Aug. 11. The paper, “Climate Information? Embedding Climate Futures within Social Temporalities of California Water Management,” was published this spring in the journal Environmental Sociology.

Over hundreds of millions of years of evolution, nature has produced a myriad of biological materials that serve either as skeletons or as defensive or offensive weapons. Although these natural structural materials are derived from relatively sterile natural components, such as fragile minerals and ductile biopolymers, they often exhibit extraordinary mechanical properties due to their highly ordered hierarchical structures and sophisticated interfacial design. Therefore, they are always a research subject for scientists aiming to create advanced artificial structural materials.

Through microstructural observation, researchers have determined that many biological materials, including fish scales, crab claws and bone, all have a characteristic “twisted plywood” structure that consists of a highly ordered arrangement of micro/nanoscale fiber lamellas. They are structurally sophisticated natural fiber-reinforced composites and often exhibit excellent damage tolerance that is desirable for engineering structural materials, but difficult to obtain. Therefore, researchers are seeking to mimic this kind of natural hierarchical structure and interfacial design by using artificial synthetic and abundant one-dimensional micro/nanoscale fibers as building blocks. In this way, they hope to produce high-performance artificial structural materials superior to existing materials.
