Leia o texto sobre adulterações em bebidas alcoólicas.
“Nos últimos cinco anos, pesquisadores brasileiros passaram a estudar o grau de adulteração em produtos nacionais e estrangeiros a partir da análise da quantidade existente, em seu conteúdo, da forma estável mais pesada do átomo de carbono, o isótopo denominado carbono 13 (13C), muito mais raro do que o leve carbono 12 (12C). A relação entre o número de átomos desses dois tipos de carbono pode denunciar a adoção de alguns procedimentos ilegais, ou no mínimo não muito divulgados, durante a fabricação de bebidas.

Re-Planting a Forest, One Drone at a Time
That funny little buzz you hear in the forest may not just be the hum of summer insects. In the near future it could be a small fleet of drones, coming to replant and restore forests that have been stripped of trees by industrial-scale deforestation. It’s all part of an ambitious plan by BioCarbon Engineering, a U.K.-based startup on a global mission to battle widespread clear-cutting, which strips more than 26 billion trees off the planet each year. CEO Lauren Fletcher, who spent 20 years as an engineer with NASA, says the only way to fight industrial-scale deforestation is with industrial-scale reforestation. Their idea: plant 1 billion trees a year. The first targets are in South Africa and the Amazonian jungles, both of which have suffered from widespread forest eradication.
BioCarbon’s reforestation scheme is simple and efficient. Here’s a quick look at how it plans to deploy its drone fleet:
1 Do a 3-D aerial survey. First, drones are sent to fly over a potential planting zone, snapping photos that create 3-D maps of the area to be reforested. The number of drones will vary depending up on the size of the seeding.
2 Create a seeding plan. Once all that terrain data has been analyzed, it then generates a seeding pattern that best suits the terrain.
3 Load the seed pods. The drones, which are equipped with guidance and control software, carry pressurized canisters of seed pods with germinated seeds immersed in a nutrient-rich gel.
4 Hover and plant. Flying at a height of 1 or 2 meters, the drones follow the planting patterns, firing the biodegradable seed pods down to the ground. The pods break open upon impact, allowing the germinated seed a chance to take root.
5 Monitor growth. After planting, the drones do low-level flights to assess the health of the sprouts and saplings.
Such “precision forestry,” as BioCarbon calls it, is extremely efficient. A farmer might hand plant as many as 3,000 seeds a day; Fletcher says his drones can drop up to 36,000 seed pods daily, often in areas where a human can’t reach. Working with local ecologists, BioCarbon will use the drones to spread a variety of tree species, as well as microorganisms and fungi designed to improve the soil quality. “The central focus is ecosystem restoration,” Fletcher says.
On a planetary climatological scale, Morton notes that “tropical deforestation plays a big role in global climate cycles,” claiming the accelerated pace of cutting and burning of forests accounted for 20 percent of greenhouse gas emissions in the 1990s. Fletcher and his team want to help reverse that trend. “By planting at the scale we’re looking at,” he says, “we can make a real longterm impact. We hope to do a lot of good in the world.”

What Happens to Your Body When You Drink Milk Every Day
Milk (and dairy in general) gets the blame for a lot of unwanted health outcomes. We're sure you've heard that dairy causes acne, increases inflammation and can even be the reason you're not losing weight. Spoiler: For those who aren't lactose-intolerant or allergic to dairy, research doesn't back up those claims. In fact, there are actually some impressive benefits that come with drinking a nutritious glass of milk.
Your Bone Health Might Improve
Not only is milk a great vegetarian protein source, but it's also packed with calcium and vitamin D—two nutrients that are vital for bone health. Calcium is a mineral needed to build and maintain strong bones, and vitamin D helps our body absorb calcium from the foods we eat. Since milk is a great source of both of thesenutrients, it's one of the best things to keep in your diet for bone health throughout life.
You Might Reach Your Weight Loss Goals
There are lots of misconceptions about how drinking milk can affect weight, but research shows regular consumption probably won't hurt your cause if you're trying to lose weight or maintain a healthy weight. This is largely due to the satisfying combination of carbohydrates, protein and fat found in milk. Protein and fat can help make milk super filling, which can help with weight loss. Carbs give you energy and help your body function at its best. When you're more satisfied from the foods you eat, it's easier to honor your hunger and fullness levels and stick to a healthy, balanced eating pattern.
A meta-analysis of randomized controlled trials (the gold standard of research) published in the journal Nutrients found that including dairy in a calorie-restricted diet resulted in greater weight loss and fat loss, while reducing loss of lean muscle. This doesn't mean milk is a miracle weight-loss food, though. Another review of studies found that consuming milk or other dairy products didn't result in significant weight loss, but didn't lead to weight gain either. If your goal is to lose weight or maintain a healthy weight, drinking a glass of milk each day might help, if it's a food you enjoy. You Might Lower Your Risk of Cognitive Decline
The impressive nutrition profile of milk could be a reason why it can help you stay more mentally sharp as you age. A 2021 review of studies published in Nutrition & Metabolism found that milk intake was connected with a decreased risk of Alzheimer's disease. Another study published in 2020 in the journal Nutrients found that skimmed dairy, fermented dairy and buttermilk were associated with better executive functioning. So adding some milk to your morning oats or as a side to a snack may help boost your brain health.
Researchers hypothesize that one reason milk might support healthy aging is the nutrition that it provides. Milk is a good source of calcium, protein and vitamin B12, all of which are critical nutrients for older adults.
The Bottom Line
If you aren't lactose-intolerant or allergic to dairy, it's totally OK to enjoy a regular glass of milk each day. From improving bone health to helping mitigate cognitive decline, drinking milk and incorporating other dairy items into your diet can come with some health benefits. As with any food, remember that moderation is key (an 8-ounce serving of milk probably wouldn't completely fill many of the glasses in your cupboard). Since there are dairy farmers all across the U.S., try choosing milk that is produced locally. Making a connection with a local farmer can help you get a better-quality product that takes less of a toll on the environment, too.
