When a biofilm has eaten every nearby nutrient it can, bacteria synchronize vortex-like patterns to grab more distant food.

There has been considerable interest in fisetin recently, especially for its potential as a senolytic, which clears away dysfunctional senescent cells that accumulate with aging. Researchers believe that fisetin may be useful in increasing the healthy period of life known as healthspan.
What is Fisetin?
Fisetin is a naturally occurring flavonol and part of the flavonoid family of polyphenols. Fisetin also acts as a pigment and influences the color of various fruits and vegetables. It can be found in many common fruits and vegetables, although the amounts greatly vary.

Ghrelin, the hormone that makes you hungry, also makes food, and food smells, irresistibly appealing. Karen Hopkin reports.
‘Tis the season…for overeating! But it’s not just your lack of willpower or the omnipresent holiday treats. No, you can lay some of the blame on ghrelin. Because a new study shows that ghrelin, the hormone that makes you hungry, also makes food…and food smells…irresistibly appealing. The finding appears in the journal Cell Reports. [Jung Eun Han et al, Ghrelin Enhances Food Odor Conditioning in Healthy Humans: An fMRI Study].

It isn’t unreasonable to think of drones as pesky technological nuisances. Our modern digital ecosystem regularly infringes on traditional notions of privacy and bombards our limited attention spans with stimuli. A swarm of drones hovering overhead seems like the physical manifestation of these intrusions and distractions. But we shouldn’t swat them away just yet. Drones still have practical utility and the potential to change industries.
An Expanding Market
The appeal of drones in the consumer market is obvious. They can capture video footage from exciting angles, serving the vanity of a population obsessed with self-documentation. Beyond that, drones also have commercial and civil government applications that include firefighting, farming, construction, deliveries, and insurance claims. According to Goldman Sachs Research, this contributes to a $100 billion market opportunity between 2016 and 2020.

Edible film kills bacteria in seafood
Posted in food
While it’s important to keep food of any type fresh, it’s particularly crucial with seafood, as it can become tainted with toxic bacteria. That’s why an international group of scientists is developing a transparent antibacterial film that gets eaten along with the seafood it’s covering.
A disease-carrying, newly invasive tick to the United States, the Asian longhorned tick, is poised to spread across much of North America, suggests a new study published Thursday in the Journal of Medical Entomology. According to the study, the tick might be able to live anywhere from Southeastern Canada to most of the eastern half of the U.S. and even parts of the West Coast.
The Asian longhorned tick, or Haemaphysalis longicornis, made an unwelcome splash last year, when researchers and health officials discovered it on a pet sheep in New Jersey. Any hopes that the discovery was an isolated incident faded away this year, with sightings of the tick popping up again in New Jersey and eight other states this past spring and summer (Arkansas, Connecticut, Maryland, New York, North Carolina, Pennsylvania, Virginia, and West Virginia). Since 2017, the tick has been found on pets, farm animals, and at least two people in the U.S., and it’s possible that it might have made its way here at least as early as 2010.

The first lab-grown steak will be available to buy in two years after scientists finally produced meat with the correct appearance, shape and texture of a real slice of beef.
Up to now, researchers have produced small amounts of cell-grown meat, which have been mixed together to create hamburger patties and sausages, but making an entire steak has proved elusive.
Now Israeli food technology company Aleph Farms has announced it has succeeded in using natural beef cells to grow the three dimensional structure of a minute steak which mimics the muscle and tissue of real meat.
