Bacteria start looking for gold

Many prospectors use mercury to bind gold and thus hide it from places that are difficult to access. But because mercury is toxic, a better way to recover the precious metal is needed. And now researchers may have discovered a solution. The bacterium C. metallidurans can withstand heavy metals, which means it is able to live in places that other organisms would rather stay away from.

Why do you have 2 nostrils?

Not only mammals have two nostrils, but also most fish, toads, reptiles and birds. One of the reasons that there are two is that the smell is better with two inputs for fragrances. In many animals, the nostrils are clearly separated from each other, which increases the chance of catching odors in the environment and being able to locate their source.

Researchers create a new element

An international research team from the University of Lund in Sweden has created a new element - number 115 - by colliding two other elements in a giant particle accelerator in Germany. They thereby add an element to the periodic table, the large scientific overview of all elements in the universe.

Mars: the red planet

The planet Mars The planet Mars is the second most researched planet in the solar system after Earth, and the researchers think it once looked like Earth. Mars is just like the earth a rock planet. Today, the surface of Mars is dry and dusty, but the probes and robot cars that have explored the bottom of the planet since the 1970s have found indications that there was once liquid water on Mars - and even rivers.
Lightning

Dancing red elves in the night

Summer is the season of thunder and lightning and therefore also of the (Red) Sprites: gigantic energy discharges as a result of lightning, which are visible as elongated, red flashes. Sprites are up to 40 kilometers long and consist largely of small balls of cold, ionized plasma. Sprites arise in heavy lightning They occur at a height of 70 to 80 kilometers and go down.

Akhenaten left a widow in need

What role did Akhenaten play? When the Zannanza affair played, Pharaoh Akhenaten had long been in his grave. But due to his death, his queen widow Nefertiti found himself in a difficult situation, and the throne faltered. That is why she made a fateful decision: she sent a letter to arch enemy Suppiluliuma. Circumstances surrounding Akhenaten's death and finds in his grave indicate Nefertiti as the guilty queen.

Platypus milk contains new weapon against bacteria

Australian researchers charted the structure of a protein in the platypus milk that can help us fight resistant bacteria. The protein curls in a unique way, and that probably determines the antibacterial effect. The bacterial poison in the milk probably developed because the platypus has no nipples, like other mammals.

New insight: you can inherit fear

Researchers at Emory University in the US have discovered that anxiety in mice can pass on to at least three generations. They allowed a group of mice to smell a certain scent, while giving the animals electricity shocks. The mice quickly became scared of the odor, and recoiled from it. Their young showed the same reaction pattern.

Learn something about light

"The light is on," cried the Danish physicist Ole Rømer when he discovered in 1676 that the light takes a while to get from A to B. Until then, physicists thought that the light spread immediately, so that the sun's rays could be seen, for example, when they were emitted.

The elephant fish and other strange sea creatures

The elephant fish is a favorite of the biologists. The fish has a larger brain than a human - at least in relation to body weight - and has a lot in common with us: he can recognize things, is sometimes bored and can learn to perform assignments. For a reward of course. More striking marine animals Blobvis (Psychrolutes marcidus): is a kind of jelly pudding, because it has almost no muscles and bones.

Algae are going to fight cancer

Some natural substances from medicinal plants can kill cancer cells. One is a so-called terpenoid called ingenol-3-angelate, which works against skin cancer. This substance only occurs in the resin of the Euphorbia peplus plant and is virtually impossible to produce in large quantities in the lab.

Sittard can erase 40 meters of meteorite

Every year our planet becomes around 40,000 tons heavier due to small and large meteoroids. The vast majority are so small that they burn in the atmosphere and can be seen as shooting stars. But some meteoroids are so big that the Earth's atmosphere cannot slow them down. These fall through unimpeded and only stop when they reach the surface of the earth.
