Unmanned aerial vehicles (UAVs), commonly known as drones, have already proved to be valuable tools for a wide range of applications, ranging from film and entertainment production to defense and security, agriculture, logistics, construction and environmental monitoring. While these technologies are already widely used in many countries worldwide, engineers have been trying to enhance their capabilities further so that they can be used to tackle even more complex problems.

Researchers at Pohang University of Science and Technology and the Agency for Defense Development (ADD)’s AI Autonomy Technology Center in South Korea recently developed a drone with foldable wings that could be more maneuverable than conventional . Their drone draws inspiration from the winged flying squirrel, a type of squirrel that uses loose flaps of skin attached from their wrists to their ankles to glide from tree to tree.

“The flying squirrel drone is inspired by the movements of flying squirrels, particularly their ability to rapidly decelerate by spreading their wings just before landing on trees,” Dohyeon Lee, Jun-Gill Kang and Soohee Han, co-authors of the paper, told Tech Xplore. “We initiated this research with the belief that, like flying squirrels, drones could expand their dynamic capabilities by utilizing .”

Leading health experts have warned that the US is staring down the barrel of another pandemic as bird flu spirals out of control on US farms.

So far, the H5N1 outbreak has affected nearly 1,000 dairy cow herds and resulted in more than 70 human cases, including the first confirmed death.

The US poultry industry is at significant risk, say experts from the Global Virus Network (GVN), particularly in areas with high-density farming and where personal protective practices may be lacking.

Plants are susceptible to a wide range of pathogens. For the common potato plant, one such threat is Pectobacterium atrosepticum, a bacterium that causes stems to blacken, tissues to decay, and often leads to plant death, resulting in significant agricultural losses each year.

In 2012, researchers isolated a new virus that infects and kills this bacterium—a bacteriophage named φTE (phiTE). Now, for the first time, scientists have uncovered the atomic structure of φTE, revealing a possible mechanism of infection that may be more complex than previously thought.

The study, published earlier this month in Nature Communications, is the result of a multidisciplinary collaboration between researchers from the Okinawa Institute of Science and Technology (OIST) and the University of Otago. It brings together expertise across several fields, including virology, , , protein engineering, biochemistry, and biophysics.

Scientists at the Terasaki Institute for Biomedical Innovation, in collaboration with the University of Maryland School of Pharmacy, have developed a new nanoparticle therapy that tackles obesity through two complementary mechanisms: converting energy-storing white fat into calorie-burning beige fat while simultaneously reducing obesity-related inflammation.

Their findings, published in the Journal of Controlled Release, are detailed in an article titled “Apigenin-loaded nanoparticles for obesity intervention through immunomodulation and adipocyte browning.” This innovative approach addresses key limitations of current obesity treatments by precisely targeting adipose tissue with apigenin-loaded nanoparticles—enhancing therapeutic effects while minimizing potential side effects.

The research team, led by Dr. Alireza Hassani Najafabadi and Dr. Ryan M. Pearson, engineered specialized PLGA nanoparticles to deliver the natural compound apigenin directly to fat tissue. This targeted delivery system ensures optimal therapeutic effects while minimizing potential side effects throughout the body.

Strawberry fields forever will exist for the in-demand fruit, but the laborers who do the backbreaking work of harvesting them might continue to dwindle. While raised, high-bed cultivation somewhat eases the manual labor, the need for robots to help harvest strawberries, tomatoes, and other such produce is apparent.

As a first step, Osaka Metropolitan University Assistant Professor Takuya Fujinaga has developed an algorithm for robots to autonomously drive in two modes: moving to a pre-designated destination and moving alongside raised cultivation beds. The Graduate School of Engineering researcher experimented with an agricultural robot that utilizes lidar point cloud data to map the environment.

Should you step away from the chicken wings?

For years, the conventional wisdom has been to swap out red meat for white meats like chicken and poultry to help reduce health risks like increased cholesterol, cancer, and inflammation —not to mention get a more budget-friendly protein source. But a new study links eating chicken and other poultry with a significantly increased risk of dying from gastrointestinal cancer and all other causes.

But before you put down the chicken—or roll your eyes and get back to your chicken Caesar—check out the details of the study, and what a dietitian says you should do if you’re concerned.

Reducing high blood pressure substantially lowers the risk of dementia and cognitive impairment without dementia, according to the results of a phase 3 clinical trial involving almost 34,000 patients, published in Nature Medicine. These findings highlight the potential importance of widespread adoption of more intensive blood pressure control among patients with hypertension to reduce the global disease burden of dementia.

It is estimated that the global number of people with dementia will rise from 57.4 million in 2019 to 152.8 million by 2050, with the greatest impact being in low-to middle-income countries. Previous research suggests that , such as eating a healthy diet and exercising regularly, could be the most effective way to reduce the growing global incidence of dementia.

Research has also found that people with untreated hypertension have a 42% greater risk of developing dementia in their lifetime than healthy study participants. However, only a few randomized controlled trials have tested the effect of medications that reduce blood pressure on the risk of dementia, and none have looked at it as a primary trial endpoint.
