Large - scale cleanup operations would also require different types of motors, perhaps
driven by magnetic fields or electrical current, the authors note.
Space may seem empty, but it's actually a dynamic place populated with near - invisible matter, and dominated by forces, in particular those
created by magnetic fields.
The plasma is simultaneously pushed inside the sphere at opposite ends where it is
molded by magnetic fields into a donut shape and forced to meet in the middle.
But apparently, the high and low - density lumps are partially bound together, most
likely by magnetic fields linking distant clouds of gas and dust.
Scientists have made promising steps in developing a new magnetic memory technology, which is far less susceptible to
corruption by magnetic fields or thermal exposure than conventional memory.
One theory, proposed in the 1990s, suggests that ball lightning is a plasma held
together by magnetic fields arranged in rings that link together into a knot.
The particles are attached
only by the magnetic field, giving the smaller one freedom to move in a swim - like motion with a long driving stroke and a short return stroke.
As matter is broken down around a black hole, jets of electrons are
launched by the magnetic field from either pole of the black hole at almost the speed of light.
And unlike many other subatomic particles, neutrinos have no charge, so they travel in a straight line from their source without being
deflected by the magnetic fields around stars.
Over time, it should detect tens or hundreds of cosmic rays from individual AGNs and their range of energies should clarify exactly how they were accelerated — a process thought to be
controlled by magnetic fields around the colossal black holes.
University of Virginia scientists have demonstrated that neurons in the brain that have been supplemented with a synthetic gene can be remotely
manipulated by a magnetic field.
Such a fierce stellar wind would batter the atmosphere of any planet in the habitable zone, unless that planet was
shielded by a magnetic field.
Their qubits are made from ytterbium ions held in
place by magnetic fields and lasers, a technology with its origins in atomic clocks.
What Dudik witnessed was the ultra-violet dance caused
by the magnetic field lines slipping around each other, continuously «unzipping» and reconnecting as the footpoints of the flare loops move around on the surface.
If climate change is actually driven
by magnetic fields of the earth and sun, then such metallic headgear would be a valid protection for citizens and their companion animals against the perils of non-static climate.
Due to their peculiar quantum mechanical properties, currents
induced by a magnetic field in Moebius molecules flow in the direction opposite to that they would take in normal rings.
Until recently, it was not clear what prevented the delicate filaments from being destroyed by competing gravitational forces, but Hubble Space Telescope images suggest they are supported
by magnetic fields generated near the galaxy's central black hole.
In birds, cryptochromes are also involved in the light - dependent magnetic orientation response based on Earth's magnetic field: cryptochrome 1a is located in photoreceptors in birds» eyes and is
activated by the magnetic field.
What's more, the retinal cells containing cryptochromes connect with a brain region which, when removed, hinders the bird's ability to
navigate by the magnetic field.
The direction of the curvature of the path,
caused by a magnetic field, indicated that the particle was a positively charged one but with the same mass and other characteristics as an electron.
As the name suggests, it shares many parallels with its terrestrial counterpart; it consists of cool plasma condensations falling from coronal heights towards the solar surface
guided by magnetic field lines.
Dangerous cosmic rays are deflected
by the magnetic field back out into space, and our atmosphere remains robust because of this protection.
Naval researchers, Manheimer recounts, attempted to use plasma antenna technology
aimed by magnetic fields to create a more precise «agile mirror» array.
In this plan, near - stationary protons would be dumped in the center of a small cyclotron and
accelerated by magnetic fields in spirals until they reached the cyclotron's outer edge.
In lab experiments, scientists found that the longer it took the rock to cool, the larger the resulting crystals, allowing researchers to use crystal size to determine how long a rock was hot and its electrons susceptible to
alignment by magnetic fields.
NASA might choose to extend it, but the spacecraft could still succumb any day to the intense radiation from the deadly halos of high - energy particles trapped around the
planet by magnetic fields.
Images of the sun in the far ultraviolet and in X-rays (acquired most recently by the Solar and Heliospheric Observatory spacecraft, the Yohkoh satellite, and the NIXT rockets) show that the heating of the corona is localized in solar active regions, which indicates the important role
played by the magnetic field.
Within the condensate, the spins produced something analogous to a magnetic field: The condensate behaved as if it were a charged particle being pushed around
by a magnetic field when in reality no such magnetic field existed.
