Out of Spec Reviews is known for in-depth videos of electric vehicles. The YouTube channel just posted its first review of a Tesla Cybertruck.
The Centaur upper stage has a rich legacy of launches and will add a lunar lander to the list, with the first Vulcan launch.
The first launch of the Vulcan Centaur has been delayed by five years. Missions ahead include a lunar lander and a constellation of Kuiper satellites.
Finally, he used an oscillating fan to make the droid’s domed head turn back and forth. Meanwhile, a Bluetooth speaker was inserted in the droid’s body to play droid sounds as the robot moves.
Since he could not faithfully recreate R2-D2, he called his invention R9-D9. That does not change the fact that all it takes is one look at it to know it’s Star Wars-inspired.

Ever think you’d see a single atom without staring down the barrel of a powerful microscope? Oxford University physicist David Nadlinger has won the top prize in the fifth annual Engineering and Physical Sciences Research Council’s (EPSRC) national science photography competition for his image ‘Single Atom in an Ion Trap’, which does something incredible: makes a single atom visible to the human eye.

Captured on an ordinary digital camera, the image shows an atom of strontium suspended by electric fields emanating from the metal electrodes of an ion trap—those electrodes are about 2mm apart. Nadlinger shot the photo through the window of the ultra-high vacuum chamber that houses the ion trap, which is used to explore the potential of laser-cooled atomic ions in new applications such as highly accurate atomic clocks and sensors, and quantum computing.
Several techniques currently are used to determine the pace of aging in animals and, to a lesser degree, in humans. However, the techniques used in humans lack accuracy, don’t assess aging in specific organs, are not widely available, and are expensive.
A multi-institutional research team measured the levels of nearly 5,000 human proteins in 5,676 people of all ages who were followed for as long as 15 years in five prospective longitudinal cohorts. Each measured protein was associated with specific organs, based on previous studies: adipose tissue, artery, brain, heart, immune tissue, intestine, kidney, liver, lung, muscle, or pancreas. Combinations of proteins indicated the pace of aging in each organ. Accelerated aging of one organ was found in nearly 20% of people, and accelerated aging of multiple organs was noted in ≈2%. Accelerated aging in a specific organ correlated with risk for developing disease in that organ. For example, people with accelerated heart aging (vs. those without it) had 250% higher risk for developing heart failure, and people with accelerated brain and vascular aging had nearly 60% higher risk for developing Alzheimer disease.
Various tools — from sequencing a person’s genome to measuring gene expression (e.g., the “methylome”) — are becoming available to predict a person’s risk for developing particular diseases. Will these predictions lead to interventions that lower risk? The jury is still out on that question.
A study done by Duke Health saw the procedure resulting in functioning valves and arteries that grow along with the young patient.
A kidney stone is a solid piece of material that can form in one or both of your kidneys when high levels of certain minerals are in your urine. There are several different types of kidney stones with different causes and symptoms.
One of the greatest challenges of modern physics is to find a coherent method for describing phenomena, on the cosmic and microscale. For over a hundred years, to describe reality on a cosmic scale we have been using general relativity theory, which has successfully undergone repeated attempts at falsification.
Albert Einstein curved space-time to describe gravity, and despite still-open questions about dark matter or dark energy, it seems, today, to be the best method of analyzing the past and future of the universe.
To describe phenomena on the scale of atoms, we use the second great theory: quantum mechanics, which differs from general relativity in basically everything. It uses flat space-time and a completely different mathematical apparatus, and most importantly, perceives reality radically differently.
Unless it is augmented with graphene, watching concrete dry might not be the most thrilling activity. Graphene was initially isolated in 2004 by scientists at The University of Manchester and has become iconic in materials research, with applications ranging from energy storage and water filtering to transportation and construction, including concrete.
A new future for cement is being facilitated by graphene. Soon, everyone will have the option to select the color, texture, and features that they want very soon. More significantly, though, and even more so than its practicality and beauty, the increasing global sustainability movement is rekindling interest in the possibilities of concrete enriched with graphene.
The building sector is confronted with a plethora of obstacles in light of Net Zero aims, and a viable path toward progress could be through the extensive integration of cutting-edge materials. Cement production accounts for 8–10% of worldwide CO2 emissions, making it one of the industries with the largest carbon footprints.
In a small group of veterans diagnosed with mild traumatic brain injury, treatment with a psychedelic drug, ibogaine was associated with improvements in daily function and mental health symptoms, a new study out of Stanford found.
“This could be one of the first treatments for traumatic brain injury,” said Dr. Nolan Williams, associate professor of psychiatry at Stanford, and principal study investigator. “I think it’s a moment of hope for veterans and folks with permanent neurological injury.”
The Federal Drug Administration classifies ibogaine as a Schedule I drug, citing “high abuse potential” and “no accepted medical use.” To receive the one-time dose, 30 Special Ops veterans traveled to a treatment site in Mexico where ibogaine use is unregulated.
