Genetically Modified Super-Charged Cassava Could Help Stamp Out Malnourishment In Africa

Posted by in categories: bioengineering, food, genetics

Over 800 million people depend on cassava as a main food staple. Also known as manioc and yuca, this root vegetable also makes up around 50 percent of the caloric intake of around one-third of people in sub-Saharan Africa.

Unfortunately, it isn’t the most nutritious of food sources. As a result, iron and zinc deficiencies are sky high in many parts of Africa. It’s estimated that up to 75 percent of preschool children and 67 percent of pregnant women in Nigeria are anemic as a result of iron deficiency.

However, researchers have now developed super-charged cassavas using genetic engineering to enrich the plant with significantly higher levels of both iron and zinc.

Cesarean Section — A Brief History

Posted by in categories: biotech/medical, food

While Barry applied Western surgical techniques, nineteenth-century travelers in Africa reported instances of indigenous people successfully carrying out the procedure with their own medical practices. In 1879, for example, one British traveller, R.W. Felkin, witnessed cesarean section performed by Ugandans. The healer used banana wine to semi-intoxicate the woman and to cleanse his hands and her abdomen prior to surgery. He used a midline incision and applied cautery to minimize hemorrhaging. He massaged the uterus to make it contract but did not suture it; the abdominal wound was pinned with iron needles and dressed with a paste prepared from roots. The patient recovered well, and Felkin concluded that this technique was well-developed and had clearly been employed for a long time. Similar reports come from Rwanda, where botanical preparations were also used to anesthetize the patient and promote wound healing.


In Western society women for the most part were barred from carrying out cesarean sections until the late nineteenth century, because they were largely denied admission to medical schools. The first recorded successful cesarean in the British Empire, however, was conducted by a woman. Sometime between 1815 and 1821, James Miranda Stuart Barry performed the operation while masquerading as a man and serving as a physician to the British army in South Africa.

A naked, pregnant woman lies on an angled bed inside a building. Three naked men attend her childbirth. The man on the left stands holding her belly on both sides with his hands. The man in the center is on the opposite side of the bed, with his left hand on her right hip and the right hand upraised holding a knife. The man on the right is crouching at the woman's feet holding them down with both hands.

A very small number of crops are dominating globally. That’s bad news for sustainable agriculture

Posted by in categories: food, sustainability

A new U of T study suggests that globally we’re growing more of the same kinds of crops, and this presents major challenges for agricultural sustainability on a global scale.

The study, done by an international team of researchers led by U of T assistant professor Adam Martin, used data from the U.N.’s Food and Agricultural Organization (FAO) to look at which crops were grown where on large-scale industrial farmlands from 1961 to 2014.

They found that within regions crop diversity has actually increased — in North America for example, 93 different crops are now grown compared to 80 back in the 1960s. The problem, Martin says, is that on a global scale we’re now seeing more of the same kinds of crops being grown on much larger scales.

Plastics are being glued together in the ocean by bacteria, scientists find

Posted by in categories: chemistry, food, particle physics

Researchers at Heriot-Watt University in Edinburgh used water collected from the Faroe-Shetland Channel and the Firth of Forth to set up their experiments. Plastics were added to the seawater and then incubated in conditions simulating the ocean’s surface. Within minutes, the minuscule pieces of plastic grouped together with bacteria, algae and other organic particles. The scientists are said to have been surprised to discover large masses of biopolymers formed the bulk of these plastic agglomerates. Team member Stephen Summers said: “This is a first step towards understanding how nanoplastics interact with natural biopolymers throughout the world’s oceans. ”This is very important, as it is at this small scale that much of the world’s biogeochemistry occurs. ”We found that the biopolymers envelope or engulf the nanoplastic particles, which caused the plastics to agglomerate into clumps. ”The nanoplastics, which are 100–200 times smaller than a bacterial cell, were actually incorporated into the agglomerates, which became visible to the naked eye in our lab experiments. ”The fact that these agglomerates become large enough to see raises concern, as they are likely to be seen as a food source by small marine animals.” We found that the biopolymers envelope or engulf the nanoplastic particles, which caused the plastics to agglomerate into clumps.


Researchers said micro and nano plastic particles mix with the bacteria secretions within minutes, forming clumps.

An Arkansas Teen Helped Turn Tea Leaves and Molasses Into a Supercapacitor

Posted by in categories: food, materials

In the search for people working on cheaper supercapacitors, she found herself in the lab of Noureen Siraj, Ph.D., an assistant professor of chemistry at the University of Arkansas, Little Rock. One of Siraj’s students, Samantha Macchi, had already been working on such a project for about a year and a half, figuring out how to make supercapacitor electrodes from common materials like used tea leaves, molasses, and a basic kitchen microwave oven — humble beginnings for a high-tech device. Siraj and Macchi brought Bollimpalli onto the project to learn about the work, which she later presented at ISEF. Meanwhile, Macchi and Siraj published the resulting research in January in the journal Chemistry Select.

Bollimpalli was initially assigned to a different project in the lab, but when she found out about the work on supercapacitors, she asked to switch tasks. Siraj, who is used to having high school students learn about her team’s work, quickly obliged.

“She quickly learned all the protocols, and she actually was able to explain. She brought an understanding that is missing in a lot of the high school students,” Siraj tells Inverse. “She really is good at absorbing the information.” They worked together tirelessly to help Bollimpalli nail the presentation she would later give at ISEF.

Lab-Grown Chicken Nuggets Made From Feathers to Hit Shelves

Posted by in categories: food, futurism

Is lab grown meat the future of the industry, or simply an expensive boondoggle that wealthy investors like Bill Gates and Richard Branson will eventually have to bite the bullet on? According to major players in this “cultured meat” industry, lab grown meats can replace having to actually slaughter and process these foods for human consumption, preventing animal deaths and giving rise to a new era in the food industry.


The JUST cultured meat company of California hopes to sell nuggets synthesized from chicken feathers by the end of 2018.

Parasite spread

Posted by in categories: food, neuroscience

By cats that is carried by two billion people may lead to schizophrenia, experts have warned.

Toxoplasma gondii (T. gondii) can be spread either through contract with cat litter trays or by eating uncooked meat but it is typically harmless.

However, according to a new study, the parasite could increase the chances of developing schizophrenia by 50 per cent.
