8 scientific developments in capsules

A team from the Massachusetts Institute of Technology in the United States developed a prototype water filter using the live fraction of the wood of non-flowering trees, to purify water intended for human consumption from impurities and other pathogens.

In a report published by “Le Point” French newspaper, writer Chloe Duran Parente says that this low-cost technique relies on a network of small channels interconnected in thin wood tissues to filter bubbles in the water and purify it from impurities.

After developing the idea on a theoretical level, the researchers transferred their project to the implementation stage in India by making a number of prototypes that can process a liter of water per hour. The technology has been successfully tested and has attracted the interest of the local population thanks to its affordable price and its reliance on natural materials.

The first image of the magnetic field around a black hole

Two years after taking the first image of the black hole known as “Messier 87”, 55 million light years from Earth, and that was in April of 2019, the “Event Horizon” telescope revealed a new image showing the magnetic field surrounding this The hole.

By studying the properties of polarized light that appears in the image of the “event horizon” telescope, scientists believe that it is possible to uncover many new scientific secrets about black holes.

German brain tumor vaccine

Researchers from the German Center for Cancer Research are working on developing a new vaccine for brain tumors that could constitute a real revolution in this field. The idea of ​​the vaccine is based on helping the immune system to fight the tumor by directing it to identify protein mutations of cancer cells.

After confirming the positive results in mice, the first phase of clinical trials in humans began, and so far no alarming side effects have been recorded, and the results appear to be highly encouraging, and pave the way for the start of the second phase of clinical trials.

When did the tiger shark appear?

Scientists previously believed that the ground shark appeared on Earth about 5.3 million years ago, but new studies have shown that it appeared much earlier, about 13.8 million years ago.

Global warming and displacement risks

A new environmental study shows that a one-degree rise in global warming rates – based on the current number of the world’s population – means an increase in the risk of displacement associated with river floods by 50%.

Dosage of nitrates for pregnant women

Countries in the European Union set the maximum dose of nitrates in one liter of drinking water at 50 milligrams, but a new study has shown that exposing a pregnant woman to a much lower level may negatively affect the development of the fetus.

The stillness of the oceans

The oceans play an essential role in regulating the planet’s heat and mitigating the effects of global warming. But over the past half-century, due to climate change, research has shown that the oceans have tended to rest at a rate of 6 times compared to the size of their previous movement.

Chemical connections

In order for the worker bees to be aware of the queen’s messages, these animals rely on an intricate network of communications.

When the queen releases what are known as “pheromones,” the bees near her immediately cease any activity, and send this chemical message to the rest of the hive’s members located further away.
