Ancient Mars did not have atmospheric oxygen, claims new research

Posted by in category: space

That does not mean the planet did not have life.

A new experimental study conducted by Washington University in St. Louis is defeating any hope that scientists have had that atmospheric oxygen once existed on the Red Planet, according to a press release by the institution published on Thursday.

Instead, the scientists have found that under Mars-like conditions, manganese oxides can be readily formed without any presence of atmospheric oxygen.

Scientists can now “see” things without “looking” at them using a new quantum technique

Posted by in categories: computing, quantum physics

“We also demonstrated that even very low-power microwave pulses can be detected efficiently using our protocol.”

A team of scientists has devised a means of using quantum mechanics to “view” objects indirectly. The new method could improve measurements for quantum computers and other systems. It brings together the quantum and classical worlds.

In a first, scientists produced male and female cells from a single person

It will provide a better understanding of how drugs affect men and women differently.

Scientists created male and female cells with the same genetic code from the same person for the first time. This unique set of cells could provide researchers with valuable insights into how sex chromosomes affect various diseases and their role in early development.

NASA’s Perseverance rover drops first sample on Mars, to return it to Earth one day

Posted by in category: space

“Seeing our first sample on the ground is a great capstone to our prime mission period, which ends on Jan. 6.”

NASA’S Perseverance Mars rover has dropped its first rock sample on the Red Planet’s surface. A titanium tube containing a rock sample on December 21 that was deposited on the surface of Mars is likely to be the first sample that could return to Earth. The event marks a “historic” step in the Mars Sample Return campaign.

Gene therapy could save children from a rare genetic disease

Posted by in categories: biotech/medical, genetics

This impressive achievement could potentially revolutionize how we treat cancer and immunity deficiencies.

Children born with Artemis-SCID face many challenges, from a missing repertoire of T and B cells to reduced resistance against chemotherapy used in bone marrow transplants. Additionally, malfunctioning DNA repair mechanisms increase the risk of developing graft-versus-host disease, where the donor’s immune system attacks host tissues.

That’s why researchers are trying everything to find an antidote for such a rare genetic disease and have now turned to gene therapy to treat Artemis-SCID. Gene therapy eliminates the need for donor cells.

Underground experiments in Italy search for violation of the Pauli exclusion principle

Posted by in categories: particle physics, quantum physics

They have found no signs of the event yet.

Deep in Italy’s Gran Sasso mountains, in the National Institute for Nuclear Physics’ (INFN) underground laboratories, researchers have been searching for proof of a very small violation of a fundamental quantum tenet called the Pauli exclusion principle, according to an article by Phys.org published on Monday.

The principle, that is applied to everything, dictates that electrons can only arrange themselves in certain specific ways in atoms. These arrangements make it so we are made of solid matter.

Scientists break new ground in cancer fight by ‘reinvigorating’ T cells

Posted by in category: biotech/medical

A new study develops ‘environment-modulating’ drugs that reinvigorate T-cells to once again destroy cancer cells.

T-cells, typically thought to be anti-cancer, can switch sides and work against us in the right environment (or battlefield!), according to a new study published on December 21 in Nature.

This discovery is unexpected because many extensive studies before this believed that most worn-out T-cells’ properties were “irreversible.” Simply put, they were doomed to being subpar tumor killers.

Shutting down a mysterious gene can help patients get rid of the deadliest brain cancer

Posted by in categories: biotech/medical, neuroscience

The deadly brain cancer is no longer a mystery.

Glioblastoma is one of the most dangerous cancer types affecting the human brain and spinal cord. Over 240,000 people lose their lives because of nervous system cancer annually, and in most of these cases, the leading cause of death is glioblastoma.

Its tumors spread fast and induce highly painful seizures and headaches. What’s worse is that there is no known 100 percent effective cure for this disease. US president Joe Biden’s eldest son Beau Biden and late American actor Robert Forster were also among the many victims of glioblastoma.

Twitter now displays stock and cryptocurrency prices directly in search results

Posted by in category: cryptocurrencies

Amid all the chaos, Twitter rolled out a useful feature that lets you search for listed company stocks and cryptocurrency prices.

To do this, users have to just type the dollar symbol followed by the relevant ticker symbol, e.g. “$GOOG” or “$ETH” (minus the quote marks), in the search bar and Twitter will display the current price. This also works without using the $ symbol in some instances, but it’s less consistent and doesn’t always return the stock or crypto prices as requested.

However, when it works, users will see a static image displaying Today’s stock price and a chart without any information about the X or Y axis. So good luck figuring that out. Presumably, it’s a price chart for the most recent closing price for that stock, but it’s not all that clear.
