Study shows how calcium carbonate forms composites to make strong materials such as in shells and pearls
Seashells and lobster claws are hard to break, but chalk is soft enough to draw on sidewalks. Though all three are made of calcium carbonate crystals, the hard materials include clumps of soft biological matter that make them much stronger. A study today in Nature Communications reveals how soft clumps get into crystals and endow them with remarkable strength.
The results show that such clumps become incorporated via chemical interactions with atoms in the crystals, an unexpected mechanism based on previous understanding. By providing insight into the formation of natural minerals that are a composite of both soft and hard components, the work will help scientists develop new materials for a sustainable energy future, based on this principle.
“This work helps us to sort out how rather weak crystals can form composite materials with remarkable mechanical properties,” said materials scientist Jim De Yoreo of the Department of Energy’s Pacific Northwest National Laboratory. “It also provides us with ideas for trapping carbon dioxide in useful materials to deal with the excess greenhouse gases we’re putting in the atmosphere, or for incorporating light-responsive nanoparticles into highly ordered crystalline matrices for solar energy applications.”

Researchers create fiber optic sensors that dissolve in the body
For the first time, researchers have fabricated sensing elements known as fiber Bragg gratings inside optical fibers designed to dissolve completely inside the body. The bioresorbable fiber Bragg gratings could be used for in-body monitoring of bone fracture healing and for safer exploration of sensitive organs such as the brain.
A fiber Bragg grating is an optical element inscribed in an optical fiber, which is widely used as a sensing instrument. Although fiber Bragg gratings are commonly used for applications such as real-time monitoring of the structural health of bridges or tracking the integrity of airplane wings, until now they didn’t exhibit characteristics preferred for use in the body. With a design that allows them to break down similarly to dissolvable stitches, the new glass fibers should be safe for patients even if they accidently break, according to the researchers.
“Our work paves the way toward optical fiber sensors that can be safely inserted into the human body,” said Maria Konstantaki, a member of the research team from the Institute of Electronic Structure and Laser (IESL) of the Foundation of Research and Technology - Hellas (FORTH), Greece, that fabricated and characterized the new gratings. “Because they dissolve, these sensors don’t need to be removed after use and would enable new ways to perform efficient treatments and diagnoses in the body.”

What Happens Between the Sheets? Extremely-Promising Superconductor Surprises Everyone
‘Floating’ Graphene on a Bed of Calcium Atoms
Adding calcium to graphene creates an extremely-promising superconductor, but where does the calcium go?
Adding calcium to a composite graphene-substrate structure creates a high transition-temperature (Tc) superconductor.
In a new study, an Australian-led team has for the first time confirmed what actually happens to those calcium atoms: surprising everyone, the calcium goes underneath both the upper graphene sheet and a lower ‘buffer’ sheet, ‘floating’ the graphene on a bed of calcium atoms.
Superconducting calcium-injected graphene holds great promise for energy-efficient electronics and transparent electronics.

Perfect snack for Noa! Rich in calcium, protein and other micronutrients! You just have to cut cheese into small cubes and let them dry until they lose almost all the fat and become super hard. Then bake them in the oven for 8 mins or so at 209 degrees Celsius. Crunchy and yummy .

Check out this fact! “Calcium” is not an excuse to drink cow’s milk :)
Ikaite - A calcium-carbonate mineral formed in cold, saline marine waters where calcite formation is inhibited.
What is going on when pregnant women drink milk and have diarrhea?
Some pregnant mothers have diarrhea after drinkingmilk. What is going on? There are several reasons for drinking milk and diarrhea, and different reasons should be treated differently.
1. People with lactose intolerance (90% of Chinese have lactose intolerance): Patients with lactose intolerance should control the amount of milk when taking milk. Generally, it is no problem within 200ml, but some individuals can only drink it. Very little milk or even no milk at all, otherwise it will cause bloating and diarrhea.
2. Eating cold milk: Because cold milk will affect gastrointestinal motility and cause mild diarrhea, most of the nutrients in milk cannot be absorbed by the body. It should be avoided to drink cold milk taken from the refrigerator or cellar, especially for patients with colds.
3. Allergic to milk: Some people are allergic to milk, and have gastrointestinal symptoms such as abdominal pain and diarrhea after drinking, as well as respiratory symptoms such as rhinitis, asthma, or urticaria. They should avoid drinking milk.
4. Eating oranges just after drinking milk: Eating oranges just after drinking milk will affect digestion and absorption, but also cause abdominal distension, abdominal pain, and diarrhea.
5. Avoid drinking milk with chocolate: Because the calcium in milk combines with the oxalic acid in chocolate to form calcium oxalate, it can cause dry hair, diarrhea, calcium deficiency and slow growth.

Parents must know the importance of calcium supplementation to children.
1. Features that require calcium supplementation in time
In infancy, if the child is irritable, it is difficult to fall asleep, he always sweats after falling asleep, wakes up in the middle of the night, crying, etc. This is mostly a manifestation of a child’s calcium deficiency, parents must pay attention to it , Appropriately increase calcium for children, don’t miss the timing and miss the child’s development.
2. The benefits of calcium supplementation
The most intuitive benefit of calcium supplementation is to promote the development of children’s bones and grow taller, and the growth of teeth has certain benefits for enhancing the body’s resistance. It can make the child’s body stronger and stronger, and will not easily get sick and bumps.
3. If you do not pay attention to supplementing calcium for your child, it is likely to affect your child’s life
Everyone knows that the most intuitive manifestation of calcium supplementation is the child’s height and tooth development. If parents neglect to supplement calcium for the child, the child will miss the height development period. If the child is much lower than other children of the same age, the child will also be psychologically affected to a certain extent, and many jobs now have height requirements. If the child’s employment problem is affected by the height problem, the consequences will be to the parents I will blame myself even more.
Give your children calcium in summer. Don’t just drink milk, try these fruits and vegetables.
Vegetables
Broccoli:
The average nutritional value and disease prevention effect of broccoli far exceeds that of other vegetables, ranking first, and broccoli is also rich in calcium. When supplementing for children, you can choose cold dressing or vegetable salad. Don’t cook for too long when blanching water, which will cause the loss of nutrients.
Turnip:
Radish stalks are the stems and leaves of radishes. Modern nutrition studies have shown that radish leaves are more nutritious than radishes, and the vitamin C content is only twice that of radishes. The second is the calcium content. Different radish tassels have different effects. The calcium content of every 100g carrot tassels is 350 mg, which ranks first among all vegetables. Parents can mix radish leaves or radish leaves with broad beans.
spinach:
Spinach is called a “nutritional model student” in vegetables. It not only contains a variety of vitamins needed by the body, but also calcium and iron. Adding some spinach to children when cooking noodles can not only cause children’s problems. Appetite can also supplement nutrition.
onion:
Onions are the most common food in daily life. Many parents think that onions are not suitable for children to eat. In fact, they are not. The nutrients in onions are also very rich. It not only supplements calcium for children, but also stimulates children’s appetite. Helps digestion, promotes gastrointestinal motility, and has an appetizing effect. When some children have indigestion, parents can try to match onions for their children, which has obvious effects. Onions can also play a role in sterilization and anti-cold, enhance children’s resistance, and purple onions have higher nutritional content.
Fungus:
The protein content of fungus is six times that of milk, and the content of calcium, phosphorus, iron and cellulose are also a lot. Fungus can effectively discharge foreign bodies when supplementing nutrients, and it can prevent indigestible hair, sand, Chaff has dissolution and oxidation.
Fruit nuts
grapefruit:
Grapefruit is not only sweet and sour, but also rich in nuts. It is also regarded as the most therapeutic fruit in the medical field. It has the effect of enhancing the body’s fitness and helps the body to absorb calcium and iron more easily. Grapefruit has the effect of invigorating the stomach. Children can appetite and promote digestion. Grapefruit can also be used when cooking, such as grapefruit stewed chicken with grapefruit skin, etc.
Hazelnut kernels:
Hazelnut kernels are called the king of nuts. Not only are they high in calcium,
And it has certain benefits for children’s eyesight and vision. Hazelnut itself has a fragrance, which can appetite children, help digestion and prevent constipation. Children eat hazelnuts and have the effect of repellent.
Many foods are rich in calcium. Parents can start with a variety of foods to allow children to supplement calcium in all directions. Don’t just think that they can only drink milk or supplement calcium. So many dietary combinations can be appropriately selected and tried. , Don’t let your children lose at the starting line!
