Researchers Have Found A Way To Regrow Teeth

Posted by in categories: biotech/medical, genetics

O.o! Circa 2021

False teeth could one day be a thing of the past, thanks to the discovery of an antibody that sparks the regeneration of lost teeth. By inhibiting the action of a gene called USAG-1, the antibody increases the availability of certain growth factors, and could eventually be used to help people grow a new set of pearly whites.

Publishing their work in the journal Science Advances, a team of researchers describes how they genetically modified mice to suffer from tooth agenesis, where some teeth fail to develop. Injecting pregnant mice from this line with the USAG-1 antibody, however, resulted in normal tooth development among their offspring. Moreover, a single administration of the antibody caused the growth of a whole new tooth in regular mice.

NASA gears up to deflect asteroid, in key test of planetary defense

Posted by in categories: asteroid/comet impacts, existential risks

Bet the dinosaurs wish they’d thought of this.

NASA on Monday will attempt a feat humanity has never before accomplished: deliberately smacking a spacecraft into an asteroid to slightly deflect its orbit, in a key test of our ability to stop cosmic objects from devastating life on Earth.

The Double Asteroid Redirection Test (DART) spaceship launched from California last November and is fast approaching its target, which it will strike at roughly 14,000 miles per hour (23,000 kph).

Architects create a floating exhibition space in the form of a fish eye

Posted by in categories: food, space, sustainability

The forum will now aim to educate visitors about sustainable sea farming and protecting the sea and its many wondrous species, according to an article published by designboom last week.

Developed to look like a fish’s eye

The building was designed by Danish architecture firm Kvorning Design and true to its mission it has been engineered to resemble a fish eye. That’s where the name “Salmon Eye” came from.

Adding googly (robot) eyes to autonomous cars can make them safer

Posted by in categories: robotics/AI, transportation, virtual reality

Robotic eyes on autonomous vehicles could improve pedestrian safety, according to a new study at the University of Tokyo. Participants played out scenarios in virtual reality (VR) and had to decide whether to cross a road in front of a moving vehicle or not.

When that vehicle was fitted with robotic eyes, which either looked at the pedestrian (registering their presence) or away (not registering them), the participants were able to make safer or more efficient choices.

Elon Musk reacted to Secretary Blinken’s statement “to advance internet freedom to Iranians”

Elon Musk, the SpaceX CEO, and CEO of electric car manufacturer Tesla said on Friday that he would be activating the firm’s satellite internet service Starlink in Iran. This is a response to US Secretary of State Antony Blinken’s statement that the United States took action “to advance internet freedom and the free flow of information” to Iranians.

Despite sanctions imposed on Iran, the U.S. Treasury Department on Friday issued guidance on expanding internet services available to Iranians. Following the death of 22-year-old Masha Amini’s suspicious death in the custody of Iranian authorities.

Scientists drilled two miles into the tectonic plate to understand Japan’s ‘great earthquake’

Posted by in category: energy

Scientists from the University of Texas at Austin and the University of Washington in the U.S. have discovered links to Japan’s next “great earthquake” after drilling deep into the underseas.

The researchers found that the tectonic stress in Japan’s Nankai subduction zone is less than expected after studying an earthquake fault, reported on Thursday.

“This is the heart of the subduction zone, right above where the fault is locked, where the expectation was that the system should be storing energy between earthquakes,” said Demian Saffer, director of the University of Texas Institute for Geophysics (UTIG).

New genetically engineered herpes virus kills cancer cells

Posted by in categories: biotech/medical, genetics

A genetically modified version of the herpes virus has shown great potential in treating advanced cancers, according to a report by the Institute of Cancer Research in London published on Thursday.

A promising therapy

Although the treatment is still in early trials, researchers have found that RP2, a modified version of the herpes simplex virus, managed to kill cancer cells in a quarter of patients. The patients had cancers so advanced and complicated that they had run out of treatments to try.
