Up to 2016, the biggest telescopes were composed of an array of antennas located in a particular site, like the one at Atacama Desert, in Chile. called ALMA (Atacama Large Millimeter/ Submillimeter Array). Its construction dates from 2004 and consists of sixty-six 8-to-12-meter diameter antennas aiming to receive millimeter wavelengths. Among others things, ALMA is capable of performing deep space detections, what allows to obtain information about the first stars and galaxies that emerged billions of years ago at huge distances from us. Due to the universe expansion, most of these objects’ emissions have stretched out to the millimeter and submillimeter wavelengths.
Using a technique known as interferometry – or interference pattern between the signals received by each antenna, to recompose a complete unique image- the 66 antennas at ALMA work together as though they were a single...
Biologist Dr. Daniel Fels recently published an essay in Biology on the interaction of matter and the so-called bioelectricity as a functional unity for regulation of living cells. The editor of the scientific textbook “Fields of the Cell” summarizes evidence of bioelectricity. He discusses interactions of internal bioelectricity with internal biochemical structures, as well as the sensitivity of Biosystems to external physical factors.
Fels explains “bioelectricity is generated by electrical charges of ions and molecules in an aqueous environment. Ions and oscillations of charged molecules as well as chemical reactions lead to electrical currents and electrostatic and electrodynamic fields.” This is very basic in biological systems and differs from the bio-photon discussion. Every heartbeat, nervous excitation or muscle contraction is physiologically...
Scientists have discovered that a two graphene layers can conduct electrons showing superconductivity if the two hexagonal nets are twisted against each other at a 1.1 degree angle. This finding could lead to room-temperature superconductors, a hypothetical material exhibiting superconductivity at temperatures above 0 °C (273.15 K). Most superconductors work only at temperatures close to absolute zero. Even ‘high-temperature’ superconductors are working in reality at −140 ºC. A material that displayed the property at room temperature — eliminating the need for expensive cooling — could revolutionize energy transmission, medical scanners and transport.
Increasing the temperature at which superconductivity occurs could have phenomenal technological applications
A current that could flow forever without losing any energy means transmission of power...
A star that formed at the time of the early universe has just been identified, and its unique characteristics may reveal new insights to star formation.
Stars are theorized to have formed in the collapsing dust of a nebulae, with the star forming in the centre of rotation and the planets forming in the corresponding protostellar disk. It has also been hypothesized that low-mass stars and brown dwarfs could also be formed from gravitational instabilities in the extended protostellar disc. Computer simulations to explore this idea suggest such a possibility. However, as yet they have been unable to run the simulations long enough to verify that the fragments would survive disk migration. Now the discovery of a very old star may just be able to prove that they would survive.
In a paper recently published in the Astrophysical Journal, a team led by Kevin Schlaufman report the discovery of a...
Of all the science-fiction-sounding names that have come to fruition in recent years, perhaps none is as mysterious or seemingly fictitious as time crystals. The name evokes something between Back to the Future and Donnie Darko, and the reality is perhaps crazier than either.
Two separate groups of scientists recently reported that they observed time crystals, which lends credence to the idea that this theoretical state of matter is something humans can actually create and observe. And indeed, time crystals can be grown in a child’s bedroom.
However, it requires nuclear sensors and lasers to help time crystals reach their full potential and then measure and observe them. This combination of dramatic scientific terms and shockingly simple objects is a great analogy for time crystals as a whole.
Read on to understand what they are and how they might affect our lives.
A team of scientists designed a device that can induce partial hindlimb regeneration in adult aquatic African clawed frogs (Xenopus laevis) by “kick-starting” tissue repair at the amputation site. Their findings, appearing November 6 in the journal Cell Reports, introduce a new model for testing “electroceuticals,” or cell-stimulating therapies.
“At best, adult frogs normally grow back only a featureless, thin, cartilaginous spike,” says senior author Michael Levin, developmental biologist at the Allen Discovery Center at Tufts University. “Our procedure induced a regenerative response they normally never have, which resulted in bigger, more structured appendages. The bioreactor device triggered very complex downstream outcomes that bioengineers cannot yet micromanage directly.”
The scientists 3-D printed the bioreactor...
When we think about liquids, we think about one of the four known states of matter: gas, liquid, solid and plasma (charged or ionized gas). Light being mass-less, the words liquid and light put together seems at first like an oxymoron. But not so long ago, in 2013, a theorized similar situation predicted in 2007 and called “photonic molecule” was made artificially. In these experiments, photons – quantum of electromagnetic fields, which have no rest mass and travel at the speed of light in vacuum – bind together so strongly, they behave as molecules, and so acting as if they had mass.
Another case concerning light which reproduces the physics of molecules, consists of photons confined to two or more coupled micro-optical cavities, since it reproduces the behavior of interacting atomic energy levels. For this reason, it has also been termed photonic molecule, which is an alternative...
Tractor beams are often shown in science fiction film to move heavy weight. Even if our current technology is not advanced enough to lift large load, physicists have managed to move small objects using acoustic or laser tractor beam. As mentioned in a recent article, we saw acoustic tractor beam grabbing objects from behind obstacles. This time researchers manage to build a light beam able to attract and repel particles about 100 times further than has been previously achieved.
Tractor beams have been already used to control tiny particles about 0.2 millimeters in diameter from a distance of 20 centimeters. Despite this incredible distance, the researchers claim it is still on the short end of what is possible for this tractor beam technique. Laser beam has become a useful tool for the manipulation and transport of microscopic objects in biology, physical chemistry and condensed...
Planet formation is not yet understood and to complicate matters Mercury is an anomaly – now a new ambitious mission hopes to resolve the mysteries and shed light on planet formation.
Planets and stars are theorized to have formed in the collapsing dust of a nebulae, with the star forming in the centre of rotation and the planets forming in the corresponding disk. The planetary characteristics are thus thought to be dependent on their size and distance from the central star. For example, gaseous planets – such as Jupiter, Saturn, Uranus and Neptune – are believed to have first formed as rocky planets and it was their greater size and position that allowed them to accrete and maintain a gaseous envelope.
However, although not completely understood (read more here), this understanding is based on the observed and inferred characteristics of the planets. However,...
It’s that time of year again when summer is over, and we reflect on the past year – and what a great year it has been!
In October 2018, research scientists William Brown, Dr Johanna Deinert and Jeremy Pfeiffer, along with chief engineer Scott Brown, attended the water conference in Sofia, Bulgaria, where they presented the latest results on the physical properties of water. Read the press release here. We were honored to discuss the PGQMEM(Precision Geometry Quartz Modulated Electro-Magnetically) technology with Nobel Laureate Prof Luc Montagnier.
The following month in November 2018, Dr Johanna Deinert held a workshop on the prevention of stress infarction during sports with a focus on Heart Rate Variability (HRV) biofeedback at the International Sports Congress in Hamburg. She was also invited to speak at the annual meeting of the Society for classical Electro-Acupuncture in Munich on the current knowledge on ‘water memory’.
In February 2019, research...
