- Researchers from the Max Planck Institute found proofs of cannabis use in the Jirzankal cemetery in western China.
- Observations indicate that cannabis was used in funeral and religious rituals about 2,500 years ago.
- To identify the chemical components of the samples found in the Jirzankal cemetery, gas chromatography, and mass spectrometry techniques were employed.
- These findings agree with other evidence observed elsewhere in China and Russia.
- Researchers at the University of Arkansas use a laser beam to kill cancer cells as they flow through the bloodstream.
- During the process, a laser beam designed for this purpose is incised on a vein and warms the circulating cancer cells in the blood.
- Upon receiving heat, the cancer cells expand, explode and destroy themselves, inhibiting their spread and metastasis throughout the body.
- The study published in Science Translational Medicine has been tested in people with skin cancer.
- At the University of New Mexico, a group of researchers has developed a vaccine against Alzheimer's disease.
- The vaccine has been tested experimentally in mice raised to display syndromes such as those that impact humans affected by this disease.
- During the development of this disease, neurons lose the ability to communicate with each other, and the brain progressively destroys itself.
- According to the observations, the vaccine promotes the formation of antibodies that prevent the formation of obstacles and malformations in brain neurons.
- Currently, researchers are collecting funds to develop the vaccine on a commercial scale.
- A study on the creation of the fastest RAM optical cell in the world was published by the Optical Society of America.
- The designed RAM performs read and write operations at 10 GB/s, doubling the speed of the latest generation of optical RAM.
- In the construction of the new RAM memory an old problem known as the "memory wall" has been solved.
- The proposed cell stores light instead of electricity and can be useful in the development of supercomputers.
- A study conducted at the University of Georgia indicated that the quality of the father-child relationship depends on the actions developed between them (play or caregiving) and when they are carried out (working or non-working day).
- The best father-child relationships are reached when the activities performed on non-working days are fun and centered on the children.
- In the same way, the best father-child relationships are developed when the activities carried out during the working days are focused on the care of the children.
- The research published in the journal of Family Psychology used a sample of 80 fathers and 80 children of approximately 3 years of age.
