Vertical solar panels could save farm land and transform agriculture

The design facilitates efficient land use and can even save water lost to evaporation.

Sunstall, a California-based company, has launched a vertical solar panel, Sunzaun, which can be used in existing fields and arable lands without sacrificing them for clean green energy. The installation is much like conventional solar systems, just that the system uses bifacial solar modules, and the entire array stands like a boundary wall in the field.

As countries look to move away from fossil fuels, the interest in solar energy has increased in recent years. Countries in Europe facing harsh winters are also finding new ways of tapping into solar energy, such as installing solar panels at high altitudes… More.

How a single-gene change led to a new species of monkeyflower

Monkeyflowers glow in a rich assortment of colors, from yellow to pink to deep red-orange. But about 5 million years ago, some of them lost their yellow. In the Feb. 10 issue of Science, UConn botanists explain what happened genetically to jettison the yellow pigment, and the implications for the evolution of species.

Monkeyflowers are famous for growing in harsh, mineral-rich soils where other plants can’t. They are also famously diverse in shape and color. Monkeyflowers also provide a textbook example of how a single-gene change can make a . In this case, a monkeyflower species lost the yellow pigments in the petals but gained pink about 5 million years ago, attracting bees for pollination. Later, a descendent species accumulated mutations in a gene called YUP that recovered the yellow pigments and led to production of red flowers. The species stopped attracting bees. Instead, hummingbirds pollinated it, isolating the red flowers genetically and creating a new species.

UConn botanist Yaowu Yuan and postdoctoral researcher Mei Liang (currently a professor at South China Agricultural University), with collaborators from four other institutes, have now shown exactly which gene changed to prevent monkeyflowers from making yellow. Their research, published this week in Science, adds weight to a theory that new genes create phenotypic diversity and even new species.

Anti-ageing scientists extend lifespan of oldest living lab rat

The results from Katcher’s latest study will be written up when Sima dies, but data gathered so far suggests that eight rats that received placebo infusions of saline lived for 34 to 38 months, while eight that received a purified and concentrated form of blood plasma, called E5, lived for 38 to 47 months. They also had improved grip strength. Rats normally live for two to three years, though a contender for the oldest ever is a brown rat that survived on a restricted calorie diet for 4.6 years.

“The real point of our experiments is not so much to extend lifespan, but to extend youthspan, to rejuvenate people, to make their golden years really potentially golden years, instead of years of pain and decrepitude,” Katcher said. “But the fact is, if you manage to do that, you also manage to lengthen life and that’s not a bad side-effect.”

Results from such small studies are tentative at best, but some scientists believe the work, and similar efforts by others, has potential. A preliminary study from a collaboration between Katcher and experts at the University of California in Los Angeles found that infusions of young blood plasma wound back the biological clock on rat liver, blood, heart and a brain region called the hypothalamus. Commenting on the work in 2020, Prof David Sinclair, a leading expert on ageing at Harvard medical school, said if the finding held up, “rejuvenation of the body may become commonplace within our lifetimes”.

Oldest dog EVER record broken

He has never been on a leash and eats only human food. Bobi, aged 30 years and 268 days, was crowned as the world’s oldest living dog by the Guinness World Records last week. Bobi also holds the enviable record of being officially the oldest dog to have lived on the planet.

Bobi, a 30-year-old Rafeiro do Alentejo from Portugal, is now the oldest verified dog ever.

This Vegan Egg Makes Its Debut in US Restaurants This Week

The price of eggs has more than doubled in the last year due to inflation, avian flu outbreaks, and the war in Ukraine. But demand for the breakfast and baking staple hasn’t gone down much; people like eggs, and there aren’t many viable substitutes that truly taste, look, and perform like the real thing.

An Israeli startup called Yo Egg thinks it has a solution in the form of vegan eggs. The product doesn’t share much with real eggs in terms of composition, but the company says it’s achieved a near-exact match in taste and texture.

Yo eggs are made primarily of water, vegetable oil, soy protein, and chickpea protein, with small amounts of other ingredients including potato starch, yeast, and seaweed extract. One egg has 40 calories, 1 gram of fat, no cholesterol, and 3 grams of protein.

Will Microbes Replace Machines?

Just when we are getting accustomed to artificial intelligence in our daily lives, get ready for a new disruptor: synthetic biology, or syn-bio, the design and engineering of biological systems to create and improve processes and products. It promises to become a manufacturing paradigm of the future.

Recent advances in molecular, cell, and systems biology have enabled scientists to shift their focus from research of syn-bio to design and engineering, creating some truly mind blowing applications. By using microorganisms, for example, companies can now manufacture an infinite number of things, cell by cell, from scratch. This offers new ways of producing almost everything that humans consume, from flavors and fabrics to foods and fuels.

By the end of the decade, syn-bio may be used extensively in manufacturing industries that account for more than a third of global output, according to BCG Henderson Institute, Boston Consulting Group’s strategy think tank. Various sources estimate that the syn-bio market today is about $10 billion and is expected to reach $30 billion in the next five years.

How Lab-grown meat is made

I will gladly pay you Tuesday for a hamburger today.

After a long day, you are finally at your favorite restaurant and you order the burger you have been dreaming of the whole time. The burger is gone within minutes, or seconds depending on your appetite. You call the waiter to send compliments to the chef for that delicious burger but are surprised to learn that your burger’s meat has been grown in a laboratory. How would you feel about eating lab-grown meat? Would you even care or does this scenario not make sense because you would have understood in the first bite that you are not eating “real meat”? What is lab-grown meat, anyway?

Lab-grown meat is made from animal cells, so technically, it is real meat. We can even say that cultured meat is more genuine than a plant-based one. When you consider the rapidly growing world population, resources spent on breeding the animals don’t seem sustainable in the long run at all. With all things considered, lab-grown meat might be the safest and most sustainable option for our future and might become a big part of our lives. In fact, even now, world-leading scientists and entrepreneurs are investing in lab-grown meat research to make it both affordable and delicious.

Even though it may feel a little unconventional at first, laboratory-grown meat can be the key to sustainability and meeting the meat demand without disturbing the natural balance. If you are skeptical about meat made in the laboratory and want to know how lab-grown meat is made, this video can answer all your questions!

A 30-year-old canine in Portugal is officially the world’s oldest dog

He has never been on a leash and eats only human food.

Bobi, aged 30 years and 268 days, was crowned as the world’s oldest living dog by the Guinness World Records last week. Bobi also holds the enviable record of being officially the oldest dog to have lived on the planet.

A peaceful existence that would not have been.

Guinness World Records.

It was only two weeks ago that Spike, a 23-year-old chihuahua mix from Ohio, was named the oldest living dog. Spike’s story was quite emotional as he was founded abandoned as a 10-year-old dog in the parking lot of a grocery store. His current owner, Rita Kimball, decided to take him home, and he shot to fame after receiving Guinness recognition.
