Chinese tombs yield earliest evidence of cannabis use

bbc.com
  • 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.

Laser destroys cancer cells circulating in the blood

  • 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.

UNM Researchers Develop Vaccine That Could Protect Against Alzheimer's

hscnews.unm.edu
  • 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.

Greek research team has created the world’s fastest RAM

ellines.com
  • 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.

How fathers, children should spend time together

news.uga.edu
  • 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.
