A good deal of evidence points to declining kidney function as a cause of declining cognitive function in aging. There are strong correlations between loss of kidney function and risk of dementia, for example. Correlation isn’t a smoking gun in matters of aging, however: it is possible for any one of the underlying forms of molecular damage that cause aging, or for intermediate consequences of that damage, to give rise to otherwise unrelated pathologies in different parts of the body. Those pathologies appear more often in people with greater amounts of that form of damage, and thus appear correlated.

Nonetheless, there are good reasons to think that kidney failure and its downstream consequences contribute meaningful to neurodegeneration, perhaps largely by degrading the function of the vascular system. Vascular aging can cause damage and dysfunction in brain tissue via numerous mechanisms, including the pressure damage of hypertension, similar damage resulting from an acceleration of atherosclerosis, failing to delivery sufficient nutrients and oxygen to the energy-hungry brain, and disruption of the blood-brain barrier, allowing inflammatory cells and molecules into the brain.

The idea of a tritium power cell is pretty straightforward: stick enough of the tiny glowing tubes to a photovoltaic panel and your DIY “nuclear battery” will generate energy for the next decade or so. Only problem is that the power produced, measured in a few microwatts, isn’t enough to do much with. But as [Ian Charnas] demonstrates in his latest video, you can eke some real-world use out of such a cell by storing up its power over a long enough period.

As with previous projects we’ve seen, [Ian] builds his cell by sandwiching an array of keychain-sized tritium tubes between two solar panels. Isolated from any outside light, power produced by the panels is the result of the weak green glow given off by the tube’s phosphorus coating as it gets bombarded with electrons. The panels are then used to charge a bank of thin-film solid state batteries, which are notable for their exceptionally low self-discharge rate.

(betavoltaic cell or betavoltaic battery) is a type of nuclear battery which generates electric current from beta particles (electrons) emitted from a radioactive source, using semiconductor junctions. A common source used is the hydrogen isotope tritium. Unlike most nuclear power sources which use nuclear radiation to generate heat which then is used to generate electricity, betavoltaic devices use a non-thermal conversion process, converting the electron-hole pairs produced by the ionization trail of beta particles traversing a semiconductor.^[1]

Betavoltaic power sources (and the related technology of alphavoltaic power sources^[2]) are particularly well-suited to low-power electrical applications where long life of the energy source is needed, such as implantable medical devices or military and space applications.^[1].

In physics and relativity, time dilation is the difference in the elapsed time as measured by two clocks. It is either due to a relative velocity between them (special relativistic “kinetic” time dilation) or to a difference in gravitational potential between their locations (general relativistic gravitational time dilation). When unspecified, “time dilation” usually refers to the effect due to velocity.

After compensating for varying signal delays due to the changing distance between an observer and a moving clock (i.e. Doppler effect), the observer will measure the moving clock as ticking slower than a clock that is at rest in the observer’s own reference frame. In addition, a clock that is close to a massive body (and which therefore is at lower gravitational potential) will record less elapsed time than a clock situated further from the said massive body (and which is at a higher gravitational potential).

These predictions of the theory of relativity have been repeatedly confirmed by experiment, and they are of practical concern, for instance in the operation of satellite navigation systems such as GPS and Galileo.^[1] Time dilation has also been the subject of science fiction works.
