A single MRI scan of the brain using standard equipment could be enough to diagnose Alzheimer’s disease, according to new results. The research uses machine learning technology to look at structural features within the brain, including in regions not previously associated with Alzheimer’s. The advantage of the technique is its simplicity and the fact that […]
Jupiter feasted on baby planets to fuel growth Researchers constructed a model based on gravitational data from NASA’s Juno space probe and other sources to examine the core of Jupiter, finding its center is filled with planetesimals, baby planets that the massive giant used to fuel its own growth. Full story: Live Science Lack of […]
Diodes are everywhere these days as they are key elements for electronics, optics, and detection. A diode is an electronic device with two electrodes. In the obsolescent thermionic diode a heated cathode emits electrons, which flow across the intervening vacuum to the anode when a positive potential is applied to it. The device permits flow […]
Nay, nay, I say! This cannot be, That machines should e’er surpass our art. We are the masters, them the slaves, And thus it ever shall be so! They learn, ‘tis true, but they learn Only what we bid them learn, no more. They cannot understand the heart Or beauty of our words, you see […]
I think I am not assuming much if I say that we are all familiar with the concept of satellite. But just in case, I should say that a satellite, within an astronomical context, is an entity in orbit around a larger body. For example, the Earth’s companion in our journey through the Milky Way […]
Kelp forests thriving in Patagonia’s cool waters Large kelp forests are thriving and healthy in Patagonia, according to a study the region’s cold spells are maintaining the 200-year-old forests along the coast of the southern end of South America. Researchers studied roughly 40 years of surface temperature data taken along the coastline and found that […]
An atomic projectile colliding with a surface at kinetic energies in the thermal or hyperthermal range interacts with and is reflected by the electronic density well in front of the first layer of target atoms, and it is generally accepted that the repulsive interaction potential is proportional to the density of electrons extending outside the […]
Humans are unrivalled in the area of cognition. After all, no other species has sent probes to other planets, produced lifesaving vaccines or created poetry. How information is processed in the human brain to make this possible is a question that has drawn endless fascination, yet no definitive answers. Our understanding of brain function has […]
This column seems to be gaining a new subcategory, which we could name ‘Wokism as the latest historians’ epidemic’ or something like that. I have already written a couple of reviews of recent books that tried to awaken us from our outdated, Eurocentric, rationalistic and neoliberal assumptions about the essence of history (Graeber’s and Wengrow’s […]
Milky Way’s closest quasar brimming with radio emissions Using a newly developed technique known as “self-calibration,” a team of Japanese astronomers has captured revolutionary photos of the closest quasar to the Milky Way, revealing a soft band of radio emission in the quasar’s galaxy. “By applying the same technique to other quasars, we expect to […]
