Learn more about the role of your stomach and learn more about the signs and symptoms of stomach cancer that you should be aware of.
The stomach is part of the body’s digestive system, located in the upper abdomen.

Genomes are the blueprints of living creatures; chromosomes and genes within all our cells encode information about life. Genome editing technology that can change these chromosomes and genes has developed rapidly. From drug development and gene therapy, improvements to crops and livestock, to creating useful microorganisms to replace petroleum, this technology has started to have a significant impact on our societies.
Professor NISHIDA Keiji (Graduate School of Science, Technology and Innovation) has developed a new genome editing technology and established a business venture based on his research findings. He is on the front lines of genome editing in both business and research.
Black-capped chickadees have extraordinary memories that can recall the locations of thousands of morsels of food to help them survive the winter. Now scientists at Columbia’s Zuckerman Institute have discovered how the chickadees can remember so many details: they memorize each food location using brain cell activity akin to a barcode. These new findings may shed light on how the brain creates memories for the events that make up our lives.
Christian Lemon, Ph.D., an associate professor in the School of Biological Sciences at the University of Oklahoma, often thinks about temperature sensation and the brain when eating a chilled mint cookie. Now, research from his lab examining oral temperature perception has been published in The Journal of Neuroscience.
In their research, Lemon’s team investigates how cold receptors in the mouth are activated by cooling temperatures, how those signals are transmitted to the brain and how those transmissions are generated into a cooling sensation.
The dangers of AI farming.
AI could lead to new ways for people to abuse animals for financial gain. That’s why we need strong ethical guidelines.

DoorDash and Wing (an Alphabet company) have announced their first joint drone delivery service in the United States. Targeted at select customers in Christiansburg, Virginia, eligible DoorDash orders from Wendy’s can now be delivered via Wing drone.
Wendy’s orders will be delivered using a Wing drone, which can travel up to 65 mph. Upon reaching its destination, the drone will lower the order to the doorstep using a tether.
Researchers working in the Horn of Africa, also known as the Somali Peninsula have uncovered evidence showing how Middle Stone Age humans survived in the wake of the eruption of Toba, one of the largest supervolcanoes in history, some 74,000 years ago.
Modern humans dispersed from Africa multiple times, but the event that led to global expansion occurred less than 100,000 years ago. Some researchers hypothesize that dispersals were restricted to “green corridors” formed during humid intervals when food was abundant and human populations expanded in lockstep with their environments.
But a new study in Nature led by scientists at The University of Texas at Austin suggests that humans also may have dispersed during arid intervals along “blue highways” created by seasonal rivers. Researchers also found stone tools that represent the oldest evidence of archery.
“There is still significant interest and potential in industrial uses of hemp,” said Dr. Jeffrey Steiner.
How can hemp production help boost local Native American economies? This is what a $10 million grant from the U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture hopes to achieve as they recently awarded this grant to the Global Hemp Innovation Center at Oregon State University (OSU) to foster collaboration with 13 Native American Tribes across the western United States, including California, Montana, Nevada, Idaho, Washington, and Oregon with the goal of creating economic stimuli for those communities while improving hemp production.
The grant comes with four primary objectives in achieving collaboration with the 13 Tribal nations, including educational opportunities, technology development, building trade networks, and ensuring product quality. This grant comes as the 2018 Farm Bill helped legalize hemp, leading to hemp production reaching $824 million across the United States in 2021.

“The challenge is getting into those hidden places,” says Machado. “It’s rare that Aedes aegypti breeding areas are found out in the open, like on a sidewalk, because when people see them, they destroy them. But with drones, we can get into areas we just can’t otherwise.”
Birdview has carried out studies with several partners since 2021, including the United Nations, the University of São Paulo (USP), and the state-owned Brazilian Agricultural Research Corporation (Embrapa), to better understand the effectiveness of releasing the disease-fighting mosquitoes with drones. First they looked at how the mechanism of the drone and outside conditions, like wind turbulence, affected the survival rate of the mosquitoes and their ability to fly.
The results were positive, so they moved on to flight-and-release tests in the Brazilian states of Pernambuco and Paraná, as well as Florida, where they’ve been working with the Lee County Mosquito Control District to see how far the mosquitoes spread upon release. They used the “mark, release and recapture” method, which involves sterile male mosquitoes being marked with a certain color before being released and later recaptured with traps so the team could see how far they had flown. They also set traps where eggs could be laid and monitored.
