Until recently, scientists believed that only very massive nuclei could have excited zero-spin states of increased stability with a significantly deformed shape. Meanwhile, an international team of researchers from Romania, France, Italy, the USA and Poland showed in their latest article that such states also exist in much lighter nickel nuclei. Positive verification of the theoretical model used in these experiments allows describing the properties of nuclei unavailable in Earth laboratories.

More than 99.9 per cent of the mass of an atom comes from the atomic nucleus, the volume of which is over a trillion times smaller than the volume of the entire atom. Hence, the atomic nucleus has an amazing density of about 150 million tons per cubic centimeter. This means that one tablespoon of nuclear matter weighs almost as much as a cubic kilometer of water. Despite their very small size and incredible density, atomic nuclei are complex structures made of protons and neutrons. One may expect that such extremely dense objects would always take spherical form. In reality, however, the situation is quite different: most nuclei are deformed—they exhibit shape flattened or elongated along one or even two axes, simultaneously. To find the favorite form of a given nucleus, it is customary to construct a landscape of the potential energy as a function of deformation. One may visualize such landscape by drawing a map on which the plane coordinates are the deformation parameters, i.e.

On a high, dry terrace overlooking a green river valley in the Andes Mountains of Peru, sits a complex of American pyramids that may be older than the pyramids of Egypt. These structures are remnants of the ancient city of Caral, which some have called the oldest society in the Americas. Caral was built around 5000 years ago, give or take a few centuries, according to groundbreaking research published in Science back in 2001. That origin date places it before the Egyptian pyramids in Africa and roughly 4000 years before the Incan Empire rose to power on the South American continent. That history, and the shear scope of the site, prompted UNESCO, the United Nations Educational, Scientific and Cultural Organization, to dub it a World Heritage Site in 2009.

These pyramids in Peru are older than the ones in Egypt, and predate the Incan Empire by roughly 4000 years.

A Swiss firm has engineered a one-third scale model of a hybrid-electric aircraft capable of vertical take-off and landing (VTOL) or efficient short take-off and landing (STOL) operations. The nifty vehicle will soon be performing its first test flight.

The firm, called Manta Aircraft, says their new model combines the best features of a helicopter and a plane.

The craft matches an underwater glider that China builds, which is capable of traveling for weeks and over huge distances.

I have to admit, they really sound “alien-like” if you ask me. 😃

Just when we thought octopuses couldn’t be any weirder, it turns out that they and their cephalopod brethren evolve differently from nearly every other organism on the planet.

In a surprising twist, in April 2017 scientists discovered that octopuses, along with some squid and cuttlefish species, routinely edit their RNA (ribonucleic acid) sequences to adapt to their environment.

A pair of monkeys were able to “see” and recognize individual letter shapes generated by arrays of electrodes implanted in their brains – without using their eyes. Previously, sight-restoring implants were placed in the retina, but these new implants were placed in the visual cortex. They achieved the highest resolution yet for such technology.

The research took place at the Netherlands Institute for Neuroscience (NIN). The scientists wanted to develop a way to restore sight for people whose optic nerves were damaged and couldn’t benefit from retina implants. The team, led by Pieter Roelfsema, created a brain implant made of needle-like electrodes 1.5 millimeters in length. They placed it on the animals’ visual cortex, partially restoring its sight.

The visual cortex is like a cinema screen in our skull, with each area on its surface mapping to the visual field. Placing a patch of electrodes on the surface that activate like pixels will make a person “see” whatever points get activated. For example, if an L-shaped pattern of electrodes in contact with the visual cortex is activated, they will see a pixelated L.

O,.o circa 2018.

The ongoing search for the graviton—the proposed fundamental particle carrying gravitational force—is a crucial step in physicists’ long journey toward a theory of everything.

Navigating and mapping rivers has long been a central component in human exploration. Whether it was Powell exploring the Colorado’s canyons or Pizarro using the Amazon to try to find El Dorado, rivers, and our exploration of them, have been extremely important. Now, scientists have mapped out an entirely new, unique river basin. This one happens to be on an entirely different planet, and dried up billions of years ago.

Three to four billion years ago, Mars did in fact have running rivers of water. Evidence for these rivers has shown up in satellite imagery and rover samples for almost as long as we have been exploring the red planet. Since Mars has little tectonics or erosion, that evidence has remained somewhat intact until the present day.

Recently, a team of scientists developed a tool to better examine those features. They managed to stitch together an 8-trillion pixel image of the entire Martian surface. Each pixel in this incredibly detailed image represents about a 5–6 square meter area. Unfortunately, it also doesn’t seem to available to the general public just year. Whether it is or not it is sure to prove useful for a variety of research projects regarding the environment of Mars. One of the first ones, which was recently published a paper in Geology was a map of the red planet’s river “ridges”.
