A novel method for simultaneously measuring blood pressure and arterial stiffness
Arterial stiffness due to is a major contributor to cardiovascular disease but is very difficult to measure. It also can influence blood pressure readings since these rely on the time taken for arteries to return to normal ...

A quantum connection between light and motion
(PhysOrg.com) -- Physicists have demonstrated a system in which light is used to control the motion of an object that is large enough to be seen with the naked eye at the level where quantum mechanics governs ...

Precision time: A matter of atoms, clocks, and statistics
Time is of the essence, especially in communications, navigation, and electric power distribution, which all demand nanosecond precision or better. Keeping these beating hearts of technology in near-perfect global synchronization ...

Physics team calculates that graphene disks could be complete optical absorbers
(PhysOrg.com) -- In optical devices designed and used to collect light, there has always been a loss of light due to reflection, now, new research by a team of physicists from Spain and England has found, ...
New study shows correlation between summer Arctic sea ice cover and winter weather in Central Europe
Even if the current weather situation may seem to speak against it, the probability of cold winters with much snow in Central Europe rises when the Arctic is covered by less sea ice in summer. Scientists of the Research Unit ...

What happened to all the snow?
Winter seems to be on hold this year in some parts of the United States. Snowfall has been scarce so far in places that were overwhelmed with the white stuff by the same time last year.

Researchers build a probe capable of capturing the motion of electrons in a nanoparticle
(PhysOrg.com) -- Scientists have known for quite some time that when light strikes objects, electrons are excited causing a tiny bit of oscillation to occur that results in the creation of an electric field. They also know ...

Oscillation
Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples include a swinging pendulum and AC power. The term vibration is sometimes used more narrowly to mean a mechanical oscillation but sometimes is used to be synonymous with "oscillation". Oscillations occur not only in physical systems but also in biological systems and in human society.
