Cancer cells (Melanoma) reach the brain by Immune System "fraud".

Researchers at Tel Aviv University led by Prof. Neta Erez, and Dr. Hila Doron and research student Malak Amer, found that metastases of violent skin cancer (melanoma) reach the brain by immune system "fraud".
They "impersonate" the cells of the immune system itself, which are recruited to combat simulated tissue damage in the brain. 
The researchers have developed a method to neutralize the mechanism of deception that may prevent metastasis in melanoma patients in the future. 
The research (link to the study), was carried out in collaboration with Prof. Ronit Satchi-Fainaro, head of the Cancer and Nanotechnology Research Laboratory, at Tel Aviv University.

"Melanoma skin cancer is known to be a violent and deadly disease, mainly because it sends metastases to vital organs in the body, and in many cases to the brain," says Professor Erez. 
"We wanted to find out how cancer cells reach brain defenses and penetrate them t…

Scientists from Israel developing treatment for skin cancer using nanoparticles

Treatment for skin cancer using nanoparticles immunotherapy. The strategy shows impressive results in mice.
New anti-cancer treatments apply immunotherapy: harnessing the immune system to combat the tumor. 

Clinical use of anti-cancer drugs such as 'Pembrolizumab' (Keytruda) and Ipilimumab (Yervoy) has given hope to many cancer patients, primarily those suffering from melanoma. 
Studies show that 60 percent of melanoma patients respond to immunotherapy treatments.  The rest have to wait for the development of novel therapies. Researchers from Tel Aviv University, in collaboration with scientists from the Weizmann Institute, the University of Lisbon in Portugal, and the University of Turin in Italy, have developed a new treatment for melanoma.  Integrates three strategies: Immunotherapy, addressing the tumor microenvironment, and nano-particle vaccination. The combined therapy activates immune cells against cancer cells. 
Inhibits the tumor microenvironment from interfering with their…

Researchers found a way to differentiate male and female sperm cells easily.

Researchers found a way to differentiate male and female sperm cells easily. Materials that slow the movement of X spermIn most mammals, half of the offsprings are females, and the other half are males. 
For humans, this ratio maintained, and women are about 49.5 of the human population. 
The egg always contains an X chromosome while the sperm can contain an X and lead to a female, or a Y leading to a male. 
The likelihood of each type of sperm cell is almost equal.
So far, IVF processes have been entirely randomized in neonatal sex. 
There was no way to separate the X and Y sperm in a way that would leave them intact and capable of fertilizing the egg.

Is there a mysterious disease among e-cigarette consumers?

At least three fatalities from lung disease in the US. Doctors fear they are originating from the e-cigarette and cannabis use through vaporizers.
The US Department of Health urges the public to consider using the e-cigarette. "We trust in the work of the FDA, and the US health authorities in their work on truth research."
At least three people died of a mysterious lung disease that doctors fear may originate from the e-cigarette and cannabis vaporizers.
Last week, a patient from Indiana, who died in the United States, was reported, and two more deaths from the state of Illinois and Oregon were reported by the CDC.
Now the CDC is calling on the public to avoid using e-cigarettes.
"Until we have no reason, and while this investigation is ongoing, we advise people to think twice about using e-cigarettes."
Federal authorities are investigating 450 possible cases of mysterious lung disease related to vaporizers. As mentioned, it is unclear exactly what causes the disease.

Space documentary - The telescopes, open the way to a deeper understanding of nature

Science documentary 2019A telescope is the primary instrument used for astronomy. A telescope is usually seen as an instrument to increase the image, but the main objective of the astronomical telescope is to collect light.
The telescopes are divided into several types, which differ according to the optical structure. The guiding principle of all types of telescopes is the collection of light by a large optical element and its concentration in a common focus.
space documentary 2019. Telescopes are also different depending on the type of radiation they are sensitive to. There are telescopes at all wavelengths, from telescopes that absorb radiation emitted from the most energetic sources in the universe - gamma and x radiation, UV-sensitive telescopes, infrared radiation, and radio radiation.

The rule of thumb is that the larger the telescope with the larger optical element, the greater the amount of light it receives.

The telescopes are also distinguished according to their purpose: the…

How intestinal bacterial fatty acids reach the brain. Can it affect the sensation of hunger?

In recent years, there has been a growing interest in the relationship between the intestinal bacteria population, and the risk of obesity and high sugar levels in the blood - the two main characteristics of the metabolic syndrome, namely risk factors for type 2 diabetes and heart disease. 

A decade ago, a researcher from the University of Washington in Missouri published a groundbreaking paper showing that intestinal bacteria can cause obesity in mice. This has paved the way for many human studies and the identification of microbes that are involved in obesity or can prevent it. 

In recent years, fecal implantation treatments have been developed that change the population of bacteria in the human intestine. These treatments have had promising results in the treatment of diabetes, and are now being tested for their effectiveness against obesity.

The Bitter Chocolate Myth, How Did Dark Chocolate Win the Status of a Super Food?

Its positive effect on health is probably marginal at most, and is consumed with high amounts of sugar. So how did the dark chocolate win the status of a super food?

One of the most common myths about nutrition is that bitter chocolate is good for health. Scientific studies have attributed dark chocolate to beneficial effects on cardiovascular disease, improved blood circulation, aid in coping with autoimmune diseases and more recently researchers have reported that it also improves mental functioning. Ostensibly, this is indeed ideal food.
