Mushroom coffee is a trendy new beverage blending traditional coffee with medicinal mushrooms, like chaga, lion’s mane, reishi and cordyceps. Fans of this blend claim it offers a natural energy boost, lowers stress and provides a number of other health benefits.

Manufacturers create mushroom coffee by drying and extracting the mushrooms’ purported healthful ingredients, then blending them with ground coffee beans and a tea blend. Unlike the mushroom caps you’d find in a cup of fungi, these dried and extracted mushrooms don’t make for an unappetizing brew. The result is usually a drink with a flavor and texture similar to regular coffee and with less caffeine than your average cup of Joe.

Mushroom Coofee: Is It Worth the Hype

Medicinal mushrooms like chaga, lion’s head, reishi, cordyceps, and turkey tail have been used as wellness tools in Asian cultures for centuries. They’re called adaptogens and are believed to help the body adapt and overcome stress. Research in test tubes and animals suggest some of the alleged health benefits of mushroom coffee include lowered blood pressure, increased immune system function and improved cognitive performance.

But more human studies are needed to support these claims, and some people may experience digestive discomfort from the combination of coffee and mushrooms. Chaga mushrooms in particular are high in oxalates, which can raise your risk of kidney stones. And those taking beta-blockers should avoid mushroom coffee as it could interfere with their medications.

The FAO is dedicated to promoting sustainable food production to help ensure the world’s continued ability to feed itself. One of the ways that the FAO hopes to do this is by promoting aquaponics as a viable way to grow plants and produce healthy foods. It’s a system that combines hydroponics (growing without soil) and aquaculture to create a self-contained farming ecosystem. The ammonia generated by farmed fish is converted to nitrate by specialized bacteria, which is then utilized by plants for growth. These systems can produce a variety of different fruits, vegetables and herbs. Go here

Researchers at the Jacob Blaustein Institutes for Desert Research at Ben-Gurion University of the Negev have developed a closed loop water system that grows both fish and vegetables at the same time. They’ve found that by using the waste from the fish as fertilizer for the vegetable growth, they can increase harvests and reduce energy consumption. The study was published in the journal Resources, Conservation & Recycling.

While aquaponics is an exciting technology, the environment requires careful monitoring to prevent issues such as bacterial infections or pump failures. This can be very time consuming and labor intensive, especially in larger aquaponics farms. The authors of the new study report on a deep learning model that improves hourly forecasting performance for an aquaponics ecosystem and can be used to inform automated processes that reduce manual intervention. The resulting solution is a step closer to realizing the vision of sensor-based autonomous aquaponics handling.

Carbon dioxide detector are an essential safety device in all workplaces, especially those that use or store flammable gases. A CO2 leak can be difficult to detect since it is a colorless, odorless and tasteless gas. In low concentrations it is present in the air we breathe but at higher levels it can be dangerous or even fatal. That is why it’s important to monitor CO2 concentrations and alert people in the event that a leak occurs.

These devices get the job done through electrochemical sensors which have electrodes submerged in an electrically conductive solution called an electrolyte. When carbon monoxide enters the gas-permeable compartment that houses the sensor, a chemical reaction causes an increase in the current passing through the electrolyte. The specific amount by which the current surges indicates the concentration of the target gas in the detector. Metal oxide sensors work along similar lines, but instead of a chemical solution they have circuitry that lowers the resistance to the flow of electricity depending on the presence of carbon monoxide molecules in the sensor.

There are also a variety of handheld CO2 meters that provide a real-time graph of the CO2 waveform and have the ability to be logged or programmed. These are used by industrial hygienists and first responders to identify and trace CO2 conditions.

A good rule of thumb is to install a CO detector within 15′ of any sleeping area in accordance with the manufacturer’s instructions. If your detector alarms and you feel ill, open windows, leave the room, and call 911 or the fire department immediately.
