Tomatoes are red. Sometimes they're orange or yellow or even purple. But they're never hot pink—until now, that is. Scientists recently discovered a way to change the flesh color of a few different items in the produce aisle—and their new hues boast a bevy of surprising production and health benefits.
A recent study by Weizmann Institute of Science scientists uncovered an unknown gene in betalains, nutritious red-violet and yellow pigments heavy on antioxidants and used most commonly for food dyes. With the discovery of that new gene, the scientists created a yeast that would produce betalains, and then reproduced betalain synthesis in edible plants and (inedible) flowers, including potatoes, tomatoes, eggplants, petunias, and tobacco.

Nov 30, 2018... Where did you grow up?I grew up in the southern Israeli city of Beer-Sheva, situated in the midst of the Negev desert. I remember it being a very happy childhood, filled with a sense of freedom and frequent encounters with the wild desert that surrounded me. I knew very little of the outside world; even a visit to the “big city” of Tel Aviv seemed like a daring adventure. After completing elementary school, my family relocated to New York City due to my father’s job position, which was a tremendous culture shock for me. I started high school in the Manhattan Lennox high school, not speaking a single word of English, knowing anyone, or being familiar with NYC ’80’s culture. But my quick acclimation into this new setting taught me an important lesson that I carry with me until this day: willpower, perseverance, and belief in myself could help me overcome even the most extreme of challenges. My NYC high school days ended up being a period of intense learning and self-development and a nurturing encounter with the world. Following my high school graduation, I returned home to serve (like any 18 year old) in the Israeli army, as a naval submariner (final rank of captain) for over 4 years. This was another significant period of development of leadership skills, comradery with my best friends until this day, and, most importantly, the development of intuitive troubleshooting skills, with an ever-lasting confidence that everything is solvable and doable.

Every time we swallow food, cells that line the intestines must step up their activity in a sudden and dramatic manner. According to a new study by Weizmann Institute of Science researchers, reported in Science, they rise to the challenge in the most economic fashion.

Your body is composed of about 10 million human cells. It’s also home to about 100 trillion tiny microbes, mainly bacteria, that wield astonishing power over your health.
Many influences, from genetics, to diet and stress, contribute to the makeup of your microbiome — the collective community of microbes as personal as a fingerprint.
Understanding, manipulating and balancing the microbiome could play an increasing role in preventing and curing diseases.

Hermitia illucens, the black soldier fly, is harmless, nutritious, and a renewable source of protein.
Flies are packed with protein and nutritious fat, and they grow quickly when fed on organic waste. One fly in particular, the black soldier fly (Hermitia illucens), could potentially provide an alternative, sustainable source of protein in animal feed, and companies around the world are looking into the possibility. A new company founded by three recent Weizmann Institute of Science graduates means to advance the edible insect industry by freezing the eggs of these flies so that growers can better plan and control their yields.

If visions of sugarplums are still dancing in your head after the holidays, it’s time to get real. We all know what happens when we overindulge in Hanukkah sufganiyot or Christmas fruitcake, and it’s not a pretty picture.
After one too many cups of eggnog or a mountain of sour cream and latkes, we resolve to slim down in the new year. Again.
How can you make your weight-loss plan more successful this time around? We reviewed Israeli research and found these suggestions for effective dieting.

Environment plays a much greater role than host genetics in determining the composition of the human gut microbiome, according to a study published today (February 28) in Nature. And including microbiome characteristics when predicting people’s traits, such as cholesterol levels or obesity, makes those estimates more accurate than only personal history, such as diet, age, gender, and quality of life, the study finds.
Feb 28, 2018... REHOVOT, ISRAEL—February 28, 2018— The question of nature vs. nurture extends to our microbiome – the personal complement of mostly friendly bacteria we carry around with us. Study after study has found that our microbiome affects nearly every aspect of our health, and that the composition of our microbes, which varies from individual to individual, may hold the key to everything from weight gain to mood. Some microbiome researchers had suggested that this variation begins with differences in our genes, but a large-scale study conducted at the Weizmann Institute of Science challenges this idea and provides evidence that the connection between microbiome and health may be even more important than we thought.
Feb 28, 2018... In just the past few years, understanding of the microbiome has transformed how we perceive diet and nutrition, and is already altering how we take care of ourselves. Weizmann Institute scientists from a range of disciplines – just some of which are immunology, neuroscience, biology, genetics, chemistry, machine learning, mathematics, and computer science – have led the way in microbiome research, regularly producing headline-making discoveries. Several of these researchers are also medical doctors, and their experience in working with patients helps move therapies more quickly from the lab to you.

Sep 20, 2014... Diet Coke is one of science’s great miracles. Ordinary Coca-Cola relies on lashings of sugar to achieve its trademark sickly sweetness – 15.9 grams per can, or about a third of the total daily intake recommended for women by Britain’s National Health Service. A can of Diet Coke, by contrast, contains no sugar at all. It owes its sweetness to aspartame and acesulfame-K, a pair of chemicals that are far sweeter than ordinary sugar, but which provide the body with no energy at all.
