Genetic discovery could spell mosquitoes’ death knell
Posted by Shubham Ghosh Roy in categories: biotech/medical, education, genetics
A UC Riverside genetic discovery could turn disease-carrying mosquitoes into insect Peter Pans, preventing them from ever maturing or multiplying.
In 2018, UCR entomologist Naoki Yamanaka found, contrary to accepted scientific wisdom, that an important steroid hormone requires transporter proteins to enter or exit fruit fly cells. The hormone, ecdysone, is called the “molting hormone.” Without it, flies will never mature, or reproduce.
Before his discovery, textbooks taught that ecdysone travels freely across cell membranes, slipping past them with ease. “We now know that’s not true,” Yamanaka said.

Scientists develop vaccine to cure deadly cancer
Posted by Paul Battista in category: biotech/medical
INDIANAPOLIS (WISH) — The survival rate for patients diagnosed with pancreatic cancer is grim. The average survival time is up to 3 and a half years. Scientists may have a cure in the form of a vaccine thanks to scientists at Memorial Sloan Kettering Cancer Center in New York.

DNA evolves at different rates, depending on chromosome structure
Posted by Shubham Ghosh Roy in categories: biotech/medical, chemistry, evolution, genetics
The structure of how DNA is stored in archaea makes a significant difference to how quickly it evolves, according to a new study by Indiana University researchers.
The study, led by molecular biologist Stephen Bell, Distinguished Professor and chair of the College of Arts and Sciences’ Department of Molecular and Cellular Biochemistry at Indiana University (IU) Bloomington, was recently published in Nature Microbiology. Its findings have the potential to impact research on the treatment of genetic diseases such as cancer.
“The most exciting thing we revealed is the idea that the shape of a DNA molecule can affect its ability to change,” Bell said. “In the early 20th century, modernist architecture had the idea that the form of a building should follow its function. But what we’re seeing in these organisms is that over time, form is actually affecting evolution. How DNA is structured can change it, creating an evolutionary feedback loop.”

Dogs trained to sniff out COVID in schools are getting a lot of love for their efforts
Posted by Quinn Sena in category: biotech/medical
A school in southeastern Massachusetts latches onto a novel program that uses canines to sniff out COVID on surfaces. The idea is to help protect kids from the virus and keep the school open.

Dr. Jessica Whited, Ph.D. — Harvard University — Exploring The Biology Of Limb Regeneration
Posted by Ira S. Pastor in categories: biotech/medical, genetics
(https://hscrb.harvard.edu/labs/whited-lab/) is an Assistant Professor of Stem Cell and Regenerative Biology at Harvard University where her lab focuses on limb regeneration in axolotl salamanders and where they develop tools to manipulate gene expression during limb regeneration, and explore signaling events following wound healing that initiate the regenerative process.
Dr. Whited earned a B.A. in Philosophy and a B.S. in Biological Sciences from the University of Missouri, and obtained her Ph.D. in Biology from MIT, where she studied in Dr. Paul Garrity’s laboratory.

Meet The High-Tech Urban Farmer Growing Vegetables Inside Hong Kong’s Skyscrapers
Posted by Shubham Ghosh Roy in categories: biotech/medical, robotics/AI, space, sustainability
Hong Kong, a densely populated city where agriculture space is limited, is almost totally dependent on the outside world for its food supply. More than 90% of the skyscraper-studded city’s food, especially fresh produce like vegetables, is imported, mostly from mainland China. “During the pandemic, we all noticed that the productivity of locally grown vegetables is very low,” says Gordon Tam, cofounder and CEO of vertical farming company Farm66 in Hong Kong. “The social impact was huge.”
Tam estimates that only about 1.5% of vegetables in the city are locally produced. But he believes vertical farms like Farm66, with the help of modern technologies, such as IoT sensors, LED lights and robots, can bolster Hong Kong’s local food production—and export its know-how to other cities. “Vertical farming is a good solution because vegetables can be planted in cities,” says Tam in an interview at the company’s vertical farm in an industrial estate. “We can grow vegetables ourselves so that we don’t have to rely on imports.”
Tam says he started Farm66 in 2013 with his cofounder Billy Lam, who is COO of the company, as a high-tech vertical farming pioneer in Hong Kong. “Our company was the first to use energy-saving LED lighting and wavelength technologies in a farm,” he says. “We found out that different colors on the light spectrum help plants grow in different ways. This was our technological breakthrough.” For example, red LED light will make the stems grow faster, while blue LED light encourages plants to grow larger leaves.
Researchers from the University of Copenhagen found an alternative route that certain cells take to make organs and used that knowledge to exploit a new type of stem cells as a potential source of organs in a dish.
