Headworn tech from a University of Michigan startup could protect agricultural and industrial workers from airborne pathogens.

Taza Aya has created a hard hat with an air curtain that prevents nearly all aerosols from reaching the face, using nonthermal plasma to ensure air purity. Proven effective in tests, this innovative device is designed for industries needing strong respiratory protection and will be available by 2025.

Microbes that are used for health, agricultural, or other applications need to be able to withstand extreme conditions, and ideally the manufacturing processes used to make tablets for long-term storage. MIT researchers have now developed a new way to make microbes hardy enough to withstand these extreme conditions.

Their method involves mixing bacteria with food and drug additives from a list of compounds that the FDA classifies as “generally regarded as safe.” The researchers identified formulations that help to stabilize several different types of microbes, including yeast and bacteria, and they showed that these formulations could withstand high temperatures, radiation, and industrial processing that can damage unprotected microbes.

In an even more extreme test, some of the microbes recently returned from a trip to the International Space Station, coordinated by Space Center Houston Manager of Science and Research Phyllis Friello, and the researchers are now analyzing how well the microbes were able to withstand those conditions.

Like a scene from the movies, a team of researchers from Singapore University of Technology and Design (SUTD) has developed new ways to freely produce and customize the food that we eat.

Their findings have been published in the journal Future Foods as “Multi-material direct ink writing 3D food printing using multi-channel nozzle.”

Three-dimensional (3D) printing using food ingredients is currently the favored approach to shaping foods with unique structures, textures, and nutritional compositions.

A compact, lightweight sensor system with infrared imaging capabilities developed by an international team of engineers could be easily fitted to a drone for remote crop monitoring.

This flat-optics technology has the potential to replace traditional optical lens applications for environmental sensing in a range of industries.

This innovation could result in cheaper groceries as farmers would be able to pinpoint which crops require irrigation, fertilization and pest control, instead of taking a one-size-fits-all approach, thereby potentially boosting their harvests.

The study notes, “Our study shows that the environmental resilience of S. caninervis is superior to that of some of highly stress-tolerant microorganisms and tardigrades.”

What plants would be most suitable for a future Mars settlement? This is what a recent study published in The Innovation hopes to address as a team of researchers from the Chinese Academy of Sciences investigated how the desert moss known as Syntrichia caninervis (S. caninervis) can survive extremely harsh conditions, specifically conditions on the planet Mars. This study holds the potential to help researchers, engineers, and future Mars astronauts better understand the types of plants they can grow, and even eat, while living on the Red Planet.

For the study, the researchers subjected S. caninervis to a series of brutal tests, including severe dryness, freezing temperatures, and large doses of gamma radiation, all of which are the environmental conditions on Mars and far harsher than humans and plants can manage. However, the researchers discovered that S. caninervis was able to recover 98 percent of its water loss within seconds after being severely dried out. The moss also achieved full recovery after being subjected to-80 degrees Celsius-112 degrees Fahrenheit) for 3 to 5 years along with-196 degrees Celsius (−320 degrees Fahrenheit) for 15 to 30 days.

A theoretical model for the illumination of photosynthesizing algae in giant clams suggests principles for high efficiency collection of sunlight.

Crops on a farm capture only about 3% of the available solar energy, much less than the 20%–25% captured by large solar arrays. Now a research team has used a theoretical model to explain efficiencies as high as 67% for photosynthesizing algae hosted by giant clams [1]. The researchers argue that clams achieve this performance with an optimized geometry. The mollusks may also adjust the algae clusters’ spacing according to changing light conditions. The researchers hope that an understanding of clams’ solar efficiency might help other scientists improve the efficiency of solar technology and explain aspects of the photosynthetic behavior of other ecosystems such as forests.

A photosynthetic cell can convert nearly every incoming photon to usable energy, says biophysicist Alison Sweeney of Yale University. But efficiency is much lower in larger systems such as agricultural fields. “Can we achieve near-perfect efficiencies over large land areas? This is an urgent question” as researchers try to reduce reliance on fossil fuels, Sweeney says.

Scientists at Duke-NUS Medical School have identified how the first domino falls after a person encounters an allergen, such as peanuts, shellfish, pollen or dustmites. Their discovery, published in the April issue of Nature Immunology, could herald the development of drugs to prevent these severe reactions.

It is well established that when mast cells, a type of immune cell, mistake a harmless substance, such as peanuts or dust mites, as a threat, they release an immediate first wave of bioactive chemicals against the perceived threat. When mast cells, which reside under the skin, around blood vessels and in the linings of the airways and the gastrointestinal tract, simultaneously release their pre-stored load of bioactive chemicals into the blood, instant and systemic shock can result, which can be lethal without quick intervention.

More than 10 per cent of the global population suffers from food allergies, according to the World Health Organisation (WHO). As allergy rates continue to climb, so does the incidence of food-triggered anaphylaxis and asthma worldwide. In Singapore, asthma affects one in five children while food allergies are already the leading cause of anaphylactic shock.
