Certain materials contain both electric dipoles and magnetic moments. An experiment demonstrates that these properties can be coupled in previously unrecognized ways, leading to advanced functionality. Domain patterns inverted by a uniform magnetic field.
NSD2 is the fourth protective factor of cellular senescence that our team has identified,” said Professor Mitsuyoshi Nakao. “With the discovery that NSD2 protects against cellular senescence, this study clarifies a basic mechanism of aging.
Researchers from Kumamoto University in Japan have used comprehensive genetic analysis to find that the enzyme NSD2, which is known to regulate the actions of many genes, also works to block cell aging. Their experiments revealed 1) inhibition of NSD2 function in normal cells leads to rapid senescence and 2) that there is a marked decrease in the amount of NSD2 in senescent cells. The researchers believe their findings will help clarify the mechanisms of aging, the development of control methods for maintaining NSD2 functionality, and age-related pathophysiology.
As the cells of the body continue to divide (cell reproduction), their function eventually declines and they stop growing. This cellular senescence is an important factor in health and longevity. Cell aging can also be stimulated when genomic DNA is damaged by physical stress, such as radiation or ultraviolet rays, or by chemical stress that occurs with certain drugs. However, the detailed mechanisms of aging are still unknown. Cell aging can be beneficial when a cell becomes cancerous; it prevents malignant changes by causing cellular senescence. On the other hand, it makes many diseases more likely with age. It is therefore important that cell aging is properly controlled.
Although senescent cells lose their proliferative ability, it has recently become clear that senescent cells secrete various proteins that act on surrounding cells to promote chronic inflammation and cancer development. Since senescent cells are more active than expected, cellular aging is thought to be responsible for whole body aging. This idea has been supported by reports of systemic aging suppression in aged mice after removal of accumulated senescent cells. In other words, if you can control cell aging, you may be able to control the progression of aging throughout the body.
O,.o Maybe nanomagnets could essentially collect these particles in the future or an enzyme could be introduced.
A collection of new research provides more clues about where and how microplastics are spreading.
As a child, Elon Musk would read comic books and sci-fi novels and dream of fantastical worlds. Now the tech entrepreneur is on the verge of visiting one.
Musk’s focus narrowed some 20 years ago while poking around NASA’s website. He noticed that there was no timetable for a manned mission to Mars. He later called the lack of vision “shocking.”
Musk, then already a millionaire from the sale of a software company, ditched Silicon Valley for Los Angeles, in order to be closer to the aerospace industry, and set his sights on the stars.
Keeping Covid out of Antarctica means little research will be done on the continent in 2020–2021.
Wits Researchers have demonstrated a new quantum approach for sharing a secret amongst many parties, setting a new record for the highest dimensions and parties to date.
Researchers at the University of the Witwatersrand in Johannesburg, South Africa, have demonstrated a record setting quantum protocol for sharing a secret amongst many parties. The team created an 11-dimensional quantum state and used it to share a secret amongst 10 parties. By using quantum tricks, the secret can only be unlocked if the parties trust one another. The work sets a new record for the dimension of the state (which impacts on how big the secret can be) and the number of parties with whom it is shared and is an important step towards distributing information securely across many nodes in a quantum network.
Laser & Photonics Reviews published online the research by the Wits team led by Professor Andrew Forbes from the School of Physics at Wits University. In their paper titled: Experimental Demonstration of 11-Dimensional 10-Party Quantum Secret Sharing, the Wits team beat all prior records to share a quantum secret.
Materials science researchers, led by electrical engineering professor Shui-Qing “Fisher” Yu, have demonstrated the first electrically injected laser made with germanium tin.
Used as a semiconducting material for circuits on electronic devices, the diode laser could improve micro-processing speed and efficiency at much lower costs.
In tests, the laser operated in pulsed conditions up to 100 kelvins, or 279 degrees below zero Fahrenheit.
Doctors are hoping stem cell therapy could be a weapon in the fight against coronavirus. On Friday, regenerative medicine company Mesoblast announced a 300-person trial to determine whether stem cell treatments will work in COVID-19 patients suffering from severe lung inflammation.
One hospital in New York tried it as an experiment with 12 patients, 10 of whom were able to come off of ventilators.
“What we saw in the very first patient was that within four hours of getting the cells, a lot of her parameters started to get better,” Dr. Karen Osman, who led the team at Mount Sinai, told CBS News’ Adriana Diaz.
Most FRBs originate hundreds of millions of light-years away. This one came from inside the Milky Way.
