How the Brain Processes Sensory Information From Internal Organs

Posted by in categories: biotech/medical, food, neuroscience

Summary: A new mouse study provides clues as to how the brain processes sensory information from internal organs, revealing feedback from organs activates different clusters of neurons in the brain stem.

Most of us think little of why we feel pleasantly full after eating a big holiday meal, why we start to cough after accidentally inhaling campfire smoke, or why we are hit with sudden nausea after ingesting something toxic. However, such sensations are crucial for survival: they tell us what our bodies need at any given moment so that we can quickly adjust our behavior.

Revolutionizing Infrared Sensing Could Transform Imaging Applications

Posted by in categories: biotech/medical, chemistry, food, health, military, quantum physics

The infrared (IR) spectrum is a vast information landscape that modern IR detectors tap into for diverse applications such as night vision, biochemical spectroscopy, microelectronics design, and climate science. But modern sensors used in these practical areas lack spectral selectivity and must filter out noise, limiting their performance. Advanced IR sensors can achieve ultrasensitive, single-photon level detection, but these sensors must be cryogenically cooled to 4 K (−269 C) and require large, bulky power sources making them too expensive and impractical for everyday Department of Defense or commercial use.

DARPA’s Optomechanical Thermal Imaging (OpTIm) program aims to develop novel, compact, and room-temperature IR sensors with quantum-level performance – bridging the performance gap between limited capability uncooled thermal detectors and high-performance cryogenically cooled photodetectors.

“If researchers can meet the program’s metrics, we will enable IR detection with orders-of-magnitude improvements in sensitivity, spectral control, and response time over current room-temperature IR devices,” said Mukund Vengalattore, OpTIm program manager in DARPA’s Defense Sciences Office. “Achieving quantum-level sensitivity in room-temperature, compact IR sensors would transform battlefield surveillance, night vision, and terrestrial and space imaging. It would also enable a host of commercial applications including infrared spectroscopy for non-invasive cancer diagnosis, highly accurate and immediate pathogen detection from a person’s breath or in the air, and pre-disease detection of threats to agriculture and foliage health.”

UBC team developing oral insulin tablet sees breakthrough results

Posted by in categories: biotech/medical, food, neuroscience

A team of University of British Columbia researchers working on developing oral insulin tablets as a replacement for daily insulin injections have made a game-changing discovery.

Researchers have discovered that insulin from the latest version of their oral tablets is absorbed by rats in the same way that injected insulin is.

“These exciting results show that we are on the right track in developing an insulin formulation that will no longer need to be injected before every meal, improving the quality of life, as well as mental health, of more than nine million Type 1 diabetics around the world.” says professor Dr. Anubhav Pratap-Singh (he/him), the principal investigator from the faculty of land and food systems.

Optical detection of multiple bacterial species using nanometer-scaled metal-organic hybrids

Posted by in categories: chemistry, food, nanotechnology, particle physics

Osaka Metropolitan University scientists have developed a simple, rapid method to simultaneously identify multiple food poisoning bacteria, based on color differences in the scattered light by nanometer-scaled organic metal nanohybrid structures (NHs) that bind via antibodies to those bacteria. This method is a promising tool for rapidly detecting bacteria at food manufacturing sites and thereby improving food safety. The findings were published in Analytical Chemistry.

According to the World Health Organization (WHO), every year food poisoning affects 600 million people worldwide—almost 1 in every 10 people—of which 420,000 die. Bacterial tests are conducted to detect food poisoning bacteria at food manufacturing factories, but it takes more than 48 hours to obtain results due to the time required for a bacteria incubation process called culturing. Therefore, there remains a demand for rapid testing methods to eliminate food poisoning accidents.

Responding to this need, the research team led by Professor Hiroshi Shiigi at the Graduate School of Engineering, Osaka Metropolitan University, utilized the optical properties of organic metal NHs—composites consisting of polyaniline particles that encapsulate a large number of metal nanoparticles—to rapidly and simultaneously identify food poisoning-inducing bacteria called enterohemorrhagic Escherichia coli (E. coli O26 and E. coli O157) and Staphylococcus aureus.

Drones are reshaping how rice is farmed in Vietnam

Posted by in categories: drones, food, sustainability

Vietnam is the world’s second-largest rice exporter, and XAG says its agricultural drones have become the “new favorite” of farmers that grow the crop.

Lê Thành Nguyên, at 62 years old, is one of the early adopters of agricultural drones in Vietnam. This year, he used drones on his seven-hectare rice farm for crop spraying, fertilization, and direct seeding by ordering the service from a local pilot team.
