The hormone erythropoietin, better known as epo, is one of the most talked about doping agents in the recent history of the Tour de France. In 1998, the French Festina team was disqualified in its entirety after the drug was found, and the American seven-time Tour winner (1999-2005) Lance Armstrong had to surrender his titles after accusations of using doping, including epo.
Parkinson's disease, which affects the movement centers in the brain, may arise in the digestive system. Researchers from the Van Andel Institute in Michigan in the US discovered that the risk of the disease is lower if someone's appendix is removed at a young age. The discovery was made on the basis of a national Swedish register from 1964 to the present, which includes no fewer than 1.7 million Sweden.
New types of antibiotics are being developed all over the world that are not resistant to resistant bacteria. These are the three most promising solutions. 1. Fighting bacteria with bacteria The bdellovibrio bacteriovorus invades other bacteria and eats them from within. © Alfred Pasieka / Photolibrary / Getty Images The US Army has discovered the cannibal bacterium bdellovibrio bacteriovorus.
The World Health Organization (WHO) speaks of one of the biggest epidemics of the 21st century, and every year millions of working days are lost worldwide. Work-related stress and the diseases that can accompany it are a huge burden on health care and society. Stress hormones such as cortisol and adrenaline cause the amygdala, the alarm center of the brain, to work overtime and influence the heartbeat, the fight against inflammation and much more.
Poison has always had something mysterious about it, but what are the most toxic substances? In science, the toxicity of a substance is often expressed in the LD50 unit, which indicates how much of a substance is needed to kill half a population - often mice. 5. Mercury Mercury is the 80th element in the periodic table and used to be used for dental fillings.
Science in Focus investigates the science behind Game of Thrones. This time we look at the dead. Raising the dead to life Is death reversible? If a human or animal dies in Game of Thrones, the leader of the dead brings him back to life. In the real world people cannot rise again, but a new experiment has brought us a big step closer.
We have known for some time that small cilia or cilia grow on nerve cells. However, its function was unclear. A new investigation sheds light on the mystery. Researchers at the University of California in the US, who experimented with nerve cells in petri dishes, think the hairs are related to the protein MC4R, which plays a role in obesity.
Inflammation rages, the cartilage is eaten away and the knee feels stiff. This is the painful reality for the hundreds of millions of people worldwide who suffer from osteoarthritis. But now Australian scientists from the Melbourne Stemcell Center have curbed the disease with the help of stem cells.
A healthy bladder can barely break because someone holds his pee too long. But if you often relieve the pressure on the bladder too late, it can be harmful. As a result of the overload, the bladder eventually becomes limp, so that it cannot be emptied properly anymore. Moreover, the risk of a painful bladder or urinary tract infection increases - a problem that is particularly known to drivers who are on the road for a long period of time.
Researchers at Imperial College London have genetically altered malaria mosquitoes using the CRISPR technique, with the result that the entire population to which the mosquitoes belonged has been destroyed. The scientists manipulated a gene in the mosquitoes, called doublesex, that plays a crucial role in the development of the mosquito into males and females.
1. HELMET READS THOUGHTS Researchers developed a helmet that can read thoughts based on the oxygen concentration in the blood. The method allows neurologists to communicate with paralyzed people who suffer from locked-in syndrome and cannot even blink their eyes. 2. HUMAN CELLS GROW IN PIG FETUS © Karen Kasmauski / Getty Images For the first time, scientists have succeeded in growing human stem cells in a pig embryo.
The active substance in cannabis, tetrahydrocannabinol (THC), influences how the neurons communicate with each other because it attaches itself to receptors in the brain. The receptors are common in zones that deal with well-being, memory, feeling, movement, learning, concentration and coordination.
A new electronic pill, recently tested on humans, can provide valuable knowledge about our digestion, so that the perfect diet can be tailor-made for everyone. Scientists from RMIT University in Melbourne, Australia, have developed the pill. It is 2.6 centimeters long and contains a thermometer, batteries, a transmitter and sensors for hydrogen, oxygen and carbon dioxide.
About 1 percent of adults stutter. And now we are starting to discover the cause. Various studies indicate that it is due to a disruption in the cooperation between two brain centers on either side of the frontal lobe. The center in the left hemisphere controls the speech movements, while the corresponding center in the right hemisphere inhibits speech.
The best working poisons attack the smallest building blocks in our body: the cells. They purposefully look for a molecule that they change - with horrible consequences. Because even the slightest molecular change in body cells can be fatal. In a few minutes, the bloodstream is blocked, organs fall out and cells collapse.
A new type of treatment with RNA therapy is perhaps a step in the direction of reducing psoriasis, which affects more than 200 million people worldwide. At a meeting of the American Chemical Society (ACS) in Philadelphia, researchers from the American company Exicure explained that RNA therapy in human trials has shown good results in the fight against psoriasis.
The American company Ambrosia has recently offered blood from teenagers for sale. So far 600 people have registered. The goal is to give older people a shot of youth through the blood of young people. The test is fully controlled by the company itself, which wants to collect data from the test subjects to be able to measure the effect of the blood.
Cannabis appears to be the new panacea. The controversial hemp plant appears to contain substances that are active in all kinds of diseases, from cancer to epilepsy. And now animal tests from the neurological institute in Montreal, Canada, indicate that cannabis is also good for the eyes.
Your body is full of fungi. Cells of the genus Candida live in the mouth of approximately half of all people, one in five women have fungi in her vagina and in a large majority they are on the skin and in the intestines. However, normally this does not cause any problems. The fungi thrive on the skin and mucous membranes, where they eat sugary waste and live peacefully with other microorganisms.
Around 112.5 million blood is donated worldwide every year. But unfortunately not every blood type is suitable for every patient. In blood groups A, B and AB, the surface of the red blood cells contains various sugars, so-called antigens. If you get blood with a different blood type, your immune system attacks the antigens in this blood and that is very dangerous.
Since 2002, the host of the SARS epidemic has been sought, causing around 800 people to die worldwide within two years and a multiple of them becoming ill. According to Chinese researchers Shi Zheng-Li and Cui Jie from the Wuhan Institute of Virology in China, the origin is a population of horseshoe noses (bats) in a cave in the Chinese province of Yunnan.
