Potential advancement in medicinal use of THC and reduction of risks in recreational use

Posted by in categories: biotech/medical, neuroscience

“This study is a first step in uncovering how we can mitigate risks of THC when used in medicine, and also is targeted at making cannabis safer for the general, non-therapeutic consumer,” said Dr. Tory Spindle.


Can cannabis be modified to decrease certain side effects, specifically anxiety, that is caused by tetrahydrocannabinol (THC)? This is what a recent study published in Drug and Alcohol Dependence hopes to address as a team of researchers led by the Johns Hopkins University School of Medicine investigated whether adding d-limonene, which is a known cannabis oil, to THC could help alleviate common feelings of anxiety or paranoia that cannabis users traditionally experience. This study holds the potential to help improve medicinal cannabis while decreasing risks to users of recreational cannabis, as well.

For the study, the researchers enlisted 20 healthy adult participants with an average age of 26 years old who completed 10 six-hour sessions involving them using vaporized THC alone (15 mg or 30 mg), vaporized d-limonene alone (1 mg or 5 mg), both together, and finally a placebo. The sessions were double-blinded, meaning both the researchers and participants were unaware who was vaporizing which sample.

Vast to use Starlink for space station broadband communications

Posted by in categories: internet, satellites

COLORADO SPRINGS — Commercial space station developer Vast will use SpaceX’s Starlink constellation to provide broadband connectivity for its Haven-1 station launching next year.

Vast announced April 9 that it will install laser intersatellite link terminals on its Haven-1 station to enable communications with Starlink satellites. The agreement between Vast and SpaceX extends to future space stations Vast plans to develop.

Max Haot, chief executive of Vast, said in an interview during the 39th Space Symposium that his company will use terminals supplied by SpaceX. Gwynne Shotwell, president of SpaceX, announced at the Satellite 2024 conference March 19 that SpaceX would sell laser terminals it developed for Starlink to other customers, a product offering she dubbed “Plug ’n’ Plaser.”

Scientists share warning after bird flu found in some New York City birds

Posted by in category: biotech/medical

“People don’t believe there’s wildlife here, but we’re really very, very rich in wildlife because we’re on the Atlantic Flyway and we have so many places for the birds to stop over during migration,” McMahon said.

Researchers and local students spent nearly two years collecting samples from a wide range of birds, including ones we see often like ducks and geese, to raptors.

Their findings were published earlier this month.

Just 1 Dose of New Antibiotic Class Eliminates Resistant Blood Infections in Mice

Posted by in category: biotech/medical

Scientists have figured out a whole new way to cut the legs out from underneath drug-resistant bacterial infections.

The new class of antibiotic was identified by researchers at Uppsala University in Sweden, and while it has only been tested on mice, the team hopes that further development of the drug can “make an important contribution to the ongoing struggle against antibiotic resistance.”

The unique medicine, like many other antibiotics currently in development, targets the double membrane that surrounds gram-negative bacteria, like Escherichia coli, which can cause bowel and blood infections, and Klebsiella pneumoniae, which can cause lung, bladder, and blood infections.

Scientists reconstruct assembly of the human centriole, image by image, for the first time

Posted by in category: biotech/medical

Cells contain various specialized structures—such as the nucleus, mitochondria or peroxisomes—known as “organelles.” Tracing their genesis and determining their structure is fundamental to understanding cell function and the pathologies linked to their dysfunction.

How blue-collar workers will train the humanoids that take their jobs

Posted by in categories: information science, robotics/AI, transportation

Carnegie Mellon University (CMU) researchers have developed H2O – Human2HumanOid – a reinforcement learning-based framework that allows a full-sized humanoid robot to be teleoperated by a human in real-time using only an RGB camera. Which begs the question: will manual labor soon be performed remotely?

A teleoperated humanoid robot allows for the performance of complex tasks that are – at least at this stage – too complex for a robot to perform independently. But achieving whole-body control of human-sized humanoids to replicate our movements in real-time is a challenging task. That’s where reinforcement learning (RL) comes in.

From NASA’s First Astronaut Class to Artemis II: The Importance of Military Jet Pilot Experience

Posted by in categories: military, space

On April 9, 1959, reporters and news media crammed into the ballroom of the Dolley Madison House in Washington—the location of NASA Headquarters at that time—to learn the names of the first American astronauts who came to be known as the Mercury 7. Public Information Director Walter Bonney kicked off the announcement by pointing to the seven men sitting on stage. “These are our astronaut volunteers,” he announced. “Take your pictures as you will, gentlemen.” One of those men on the dais, Deke Slayton, a test pilot from Edwards Air Force Base, recalled the pandemonium he witnessed. “I’ve never seen anything like it, before or since.” He described the event as, “a frenzy of light bulbs and questions…it was some kind of roar.” His colleague, Wally Schirra, a test pilot from Naval Air Station Patuxent River, called the media’s interest scary because he soon came to realize that their, “private lives were in jeopardy.”
