My company Astro Mechanica has invented a new kind of jet engine. Unlike any existing engine, it's efficient at every speed. Because it's efficient at every speed, we can use it in a new way: as the first stage of an orbital launch vehicle.
Driverless cars and planes are no longer the stuff of the future. In the city of San Francisco alone, two taxi companies have collectively logged 8 million miles of autonomous driving through August 2023. And more than 850,000 autonomous aerial vehic
Anyone who has learned a second language will have made an exhilarating (and yet somehow unsettling) discovery: there is never a one-to-one correspondence in meaning between the words and phrases of one language and another. Even the most banal expre
Channel 1's photorealistic news anchors come in all shapes and sizes. They can all speak more or less any language, while evoking the stiff, formal body language familiar to anyone that still watches news on the TV. They're even capable of making n
The solar wind fluctuates, but last December it surprised astronomers when it suddenly stopped completely for a couple of days. The anomaly was detected by MAVEN, a NASA orbiter studying the atmosphere of Mars, whose instruments recorded a drop in so
What's more, the human brain's neural plasticity, its ability to grow new nervous tissue and expand existing connective channels, has granted it an ability to learn from noisy, low-quality data streams, with minimal training and energy expenditure.
So why not folks? The box system is wonderful but has real limitations. This system is not easy to build inside of, but it certainly can secure a sound working environment. How about a simple drop bed for sleeping. It is clearly tall enough. A
In a continuing pursuit to create a new generation of airplane flight, i've shifted away from dedicated ionic thrusters, and toward something much more integrated. Now may be the time for ionic thrust airfoils - wings which create thrust themselves,
But there are plenty of other complicated objects in the universe. For example, galaxies can group into enormous structures (called clusters, superclusters, and filaments) that stretch for hundreds of millions of light-years. The boundary between the
Another big step towards an open, public debate over the validity of the Big Bang, expanding-universe hypothesis came September 3 with the publication in the New York Times Opinion section of an article titled "Crisis in Cosmology " (and titled o
In my neuroscience lab at the University of California, Santa Barbara, my colleagues and collaborators discovered this large repository of brain genes in the sponge. Ever since, we have asked ourselves why this ancient, porous blob of cells would c
Modelling predicted that the number of global cancer cases in under 50s will rise a further 31 percent by 2030, mostly among people aged 40-49.
The researchers acknowledged that cancer data from different countries varied greatly, with developing
Yet he had a little-known sideline ?" speculations about science. In his final work Eureka ?" A Prose Poem, published in 1848, one year before he died, Poe outlined some of his theories of the cosmos. His aims were most ambitious, especially for
Dogs have extraordinary noses. They can smell explosives and accelerants for arson, and the tiniest traces of narcotics, no matter how well masked or concealed. With a sniff, they can tell whether a new friend at the dog park is male or female. The
The camera zooms in on the person's arm to reveal the cells, then a cell nucleus. A DNA strand grows on the screen. The camera focuses on a single atom within the strand, dives into a frenetic cloud of rocketing particles, crosses it, and leaves us
Scientists have come to realize that in the soil and rocks beneath our feet there lies a vast biosphere with a global volume nearly twice that of all the world's oceans. Little is known about these underground organisms, who represent most of the p
In May, Haag was finishing her first year of graduate school at the University of Colorado, Boulder, where Kertzer was an undergraduate. Both looked forward to a break from classes. Haag planned to explore new hikes and climbing routes. Kertzer, a Bo
When it comes to putting the viewer inside the head of a character … the movies have been stymied. In attempting to create an interior point of view, they have tried everything, from the use of a voice-over that speaks the character's thoughts, t
In our survey of pre-modern recipes we noticed a pattern of combining honey and vinegar to wash or dress wounds and swellings, and this inspired us to focus on that combination in our analysis," said Dr. Erin Connelly, a researcher on the study.
Korea's fertility rate dropped to a new low of 0.78, the lowest among countries in the Organization for Economic Cooperation and Development, and possibly the world.
Korea would need to triple its annual births to 700,000 per year to maintain
Northern lights and the Oort Cloud
Again the natural inferances drawn from Cloud cosmology surprise and actually make a wide range of known phenoms a lot clearer and even simpler.
Understand that we have reached the point of understand
This artist's concept shows the two-faced white dwarf nicknamed Janus. The blue-tinted dead cinder of a star, which was once a star like our sun, is composed primarily of hydrogen on one side and helium on the other (the hydrogen side appears bright
For years, astronomers and physicists have calculated the age of our universe by measuring the time elapsed since the Big Bang and by studying the oldest stars based on the redshift of light coming from distant galaxies. In 2021, thanks to new techni
Enamel can be worn away by abrasion, decay or teeth-grinding, and it can't be repaired by natural processes as it's the only non-living tissue in our bodies. In recent years, the rise in peroxide-based dental whitening products has exacerbated th
You might think that after centuries of studying light, we know pretty much everything about it. It's true we've had breakthrough after breakthrough in using it, from illumination to communication, from examining the micro- and macro-universes to
A Lancet review of autopsy data of over 300 post-COVID-19 vaccination deaths would challenge the mainstream narrative on the safety of the shots, but was removed within 24 hours of the initial submission, said cardiologist Dr. Peter McCullough, the p
