Bioengineers have learned how to print perfect wagyu beef on a 3D printer

Steakholder Foods, which grew out of Israeli startup MeaTech 3D, has announced a public tasting of synthetic wagyu beef for later this year. It is reported that they have managed to produce an analog of the “omakase” variety that surpasses the original in all parameters. But the main thing is that such synthetic meat is actually meat, and its properties can be varied to suit any needs.

The technology is based on the creation of “bioinks,” a semi-liquid material that can be filled into a 3D printer to print the desired structure. Biocornyls are made up of muscle fragments and fat cells grown from an animal’s stem cells. That is, it is a complete beef, initially separated into components for ease of use in 3D printing.

Steakholder Foods says it can not only reproduce the characteristic marble pattern of wagyu, but also make the meat even better. For example, they can achieve a perfect distribution of meat and fat in each piece. Or, on the contrary, to increase the nutritional value of the meat, to make it more beautiful, to adapt the appearance to create a new dish. Instead of searching the cow carcass for a suitable piece, the chef of the future will set a program for the 3D printer and immediately get what he is looking for.

Scientists have come up with an electric generator that can be assembled from ordinary sticky tape

by Moriah Skiles

written by Moriah Skiles

A team of engineers led by Gang Wang from the University of Alabama has created a curious version of a triboelectric generator that uses the simplest of components. Essentially, they are either trash or items that can be bought for a nominal sum at any hardware store. Plastic film, adhesive tape and two plates of aluminum – such a primitive device made 400 LEDs glow at once.

This is their second prototype, and it is 47% more efficient than the previous one. The plastic and adhesive tape are freely located between the metal plates, and the compression and separation of the latter generates electric charge. The advantage of the system is that the amount of charge directly depends on the pressure force, so it is possible to assemble generators of different power and size. The prototype achieved a power density of 170 W per square meter.

Ralph Appelbaum Associates has completed work on the installation of the original “Lift 109” elevator, which is located inside the giant chimney of an ancient coal-fired power station. Over its nearly century-long history, the Battersea Power Statio, believed to be the largest brick building in Europe, has become one of London’s most famous landmarks. The art deco structure has been captured in hundreds of works of art, and after the station itself closed, it was turned into an interactive museum.

Breakthrough water-laser cell proved to be thousands of times faster than conventional semiconductors

by Moriah Skiles

Initially, iodine is added to pure water, which significantly reduces its conductivity. The water is passed through a special nozzle to produce a flat liquid jet several microns thick. A laser is fired into this jet, which knocks out the iodine ions, resulting in a dramatic increase in the conductivity of the water. A second laser “reads” this change and determines which of the two positions the system is in. In this way, the operation of a classical semiconductor is mimicked.

The international assembly decided to abandon the leap second forever

by Moriah Skiles

written by Moriah Skiles

For the average person, time flows in a measured fashion, and most people give little thought to how it can affect their lives. However, it is worth knowing that time on our planet is measured in two systems – UTC and GPS. UTC time is somewhat “behind” GPS time. In order to equalize both systems, since 1972 the practice of adding so-called leap seconds has been widely used. A leap second refers to a one-second adjustment applied to Coordinated Universal Time (UTC) to account for the difference between accurate atomic time and inaccurate observed solar time, which varies due to irregularities and long-term slowing of the planet’s rotation.

The General Conference on Weights and Measures recently decided to abandon it. This decision is a historic one. On the practical side, the adoption of the new norm will help avoid problems in industries such as telecommunications, communications, and navigation, where the continuous flow of time is extremely important. The decision, for which representatives of 59 countries voted, will come into force in 2035 or earlier if a number of conditions are ensured. Russia voted against it – the Russian delegation insisted that it should take effect from 2040.

Why you shouldn’t work out what you eat in training

by Moriah Skiles

written by Moriah Skiles

Sports and fitness can increase your energy expenditure a little, but the main contributor to weight loss and weight maintenance is eating behavior.

First of all, you need to deal with what makes you consume more calories than you need. “Working off” prevents to deal closely with this issue and to establish nutrition.

A person eats too much, then runs laps around the stadium and thinks that he has atoned for his sin and everything is fine. Until the next breakdown.

Moreover, the desire to cover the food eaten by training is also ineffective. Our bodies have a ceiling of physical activity that helps us use more energy per day. Once you go beyond that level, your body starts to conserve.

Sports and fitness without considering nutrition will not result in significant weight loss. But weight loss is not the only reason to move more in your regular life.

How to get your diet back on track without stress

by Moriah Skiles

written by Moriah Skiles

Recognize the problem
And sincerely want to bring your diet back to normal. It is better to get rid of bad habits in the position of “I love myself and want to do it for me”, instead of “this is the way it should be”.

Also, before changing your diet, it’s important to break the “food = pleasure” link. Yes, junk food brings momentary pleasure, but as you are reading this text, it is probably more important for you to maintain a healthy body for years to come.

Set a specific goal
This will determine your future eating plan.

Understand whether you want to stay at your weight or lose weight. How many pounds? Or maybe you need to gain muscle mass or just maintain your health? Having a clear understanding of your goal will make it easier to get on track and stay disciplined.

Learn the principles of good nutrition
The norms of a healthy diet are individualized for everyone. However, there are general principles that are the basis for determining individual values, such as the number of calories needed per day and the optimal balance of proteins, fats and carbohydrates.

How to change your relationship with sports

by Moriah Skiles

written by Moriah Skiles

Seek out an activity to your heart’s content
Perhaps it’s the legacy of 1980s fitness culture with its “you can’t catch a fish out of a pond without work” attitude, but many people still believe that exercise without suffering doesn’t count. But this “punitive” approach negates any benefits of physical activity, and in fact, the more you enjoy a workout, the more likely you are to do it again.

If you haven’t yet found an activity that brings you joy, try anything that piques your interest: trampolining, hiking, yoga, powerlifting. The key is to stay curious and recognize that you may try many things before you find something you truly love. Many people often think like there’s something wrong with them since they don’t enjoy the sport. It’s all about the fact that certain workouts just aren’t right for them.

Ask questions at the end of a new workout
Physical activity that you enjoy doesn’t necessarily have to be easy and gentle, and you don’t necessarily have to enjoy every minute of it. We often get more satisfaction from workouts that challenge our abilities and motivate us to overcome fears and obstacles.

3 reasons why home workouts don’t get results

by Moriah Skiles

written by Moriah Skiles

1. You have chosen the wrong program
Typically, home workouts consist of simple exercises like push-ups, squats and lunges, deadlifts and presses with light fitness dumbbells. Such a program is suitable for those who want to maintain health, strengthen muscles and slightly increase overall endurance.

If your goals are to lose weight, build muscle mass or develop strength, you need a specific program.

2. You do not increase the load
Often people find a workout program, get used to it and don’t want to change anything.

At first, the exercises seem difficult. You struggle to complete the approaches, suffer from muscle pain in the morning and rejoice at the small positive changes, whether it is an increased biceps or a minus centimeter in the waist.

Over time, the body adapts, and for further progress you need to increase the volume of training, but you are already used to the program and perform it on automatic, without thinking about more.

Your body feels comfortable and good, but progress stops.

How to choose a yoga and fitness mat

by Moriah Skiles

written by Moriah Skiles

What materials are used to make mats
Knowing the characteristics of different materials, you can at least roughly imagine how the mat will feel during exercise. At the same time, there is no guarantee that the product will be of high quality, even if it is made of 100% natural polymer and is not cheap.

Because of the difference in composition and manufacturing techniques, two models of the same material may differ greatly in durability, odor and anti-slip properties.

Polyvinyl chloride
One of the most popular options. Most cheap mats are made of PVC, although there are also quite expensive models. For example, from Manduka or Reebok, a popular yoga brand.

Even cheap mats can provide a good grip on the floor, so that the product will not move with you during exercises. However, most models can’t provide the same good grip on your hands. Once your palms get wet from sweat, they will start to ride on the PVC surface.

Polyethylene foam
This material is used to make hiking mats, so-called foams. Some manufacturers indicate that such models can be used for training.

It is indeed possible to exercise on them. For example, if you are going to do exercises in nature, laying the mat on the grass wet from dew. Or throw a mat on the floor to make it softer to pump your abs.
