They are carried out at a scale so small that room temperature induces wigglings of the AFM's constituent molecules that would blur the images, so the apparatus is kept at a cool -268C.

Last year Dr Smith and Alanson Sample, a researcher at the University of Washington in Seattle, powered a small humidity and temperature sensor using nothing more than the energy gleaned from a television station 4.1km (2.5 miles) away.
To maintain the critical temperature, Dr Zheludev uses a small electronic heat pump known as a Peltier cell.
Small increases in body temperature can trigger or worsen multiple sclerosis symptoms.
Dr Amber Young, consultant paediatric anaesthetist at the South West Paediatric Burns Centre at Frenchay Hospital in Bristol and clinical adviser to the project said when a child with a small burn develops a high temperature there is no easy way of knowing if the child has a serious bacterial infection, or simply a cough or cold.
Cao Gadgets is attempting to fill that niche with its functionally named Wireless Sensor Tags -- small devices which monitor movement and temperature, notifying you if anything's amiss.

At this temperature, the mirror was able to flip between high and low reflectivity over a million times a second suggesting that, if it can be kept reliably at this critical temperature, gallium will make a fast (and also small and cheap) optical switch.
The three small black rectangles each year are the observed global temperature histories in common use.
He notes that although a detectable tilt is caused when the temperature drops by a few degrees, that tilt is too small to explain the anomalies and, in any case, it would lag roughly 30 minutes behind the shadow (because it takes time for the ground to cool) while the experimental measurements show a change in g instantaneously during an eclipse.
Highly condensed lithium polymer battery delivers an incredible amount of juice in a small form factor and features built in overcharge, short circuit, and temperature protection.

In an oxygen-free (anaerobic) environment at a certain temperature, pH and salinity, the bacteria can produce a toxin that in very small amounts can cause life-threatening paralysis.

And in 1995, there was a small piece of fabric that was sticking out and it really raised the temperature of some parts of the heat shield on re-entry.
The likely reason for that failure is that while the models recognize that increased CO2 itself will not produce a big, catastrophic increase in global temperatures, the models assume that the very small amount of warming caused by increased CO2 will result in much larger temperature increases caused by positive feedbacks.

My mother, Patricia Cockburn, took my temperature and asked Paddy McMahon, an elderly man who looked after the walled garden and our small herd of sheep, to bicycle into the town of Youghal a mile and a half away, to get a doctor.
It has long been known that some solid materials, called metal hydrides, are capable of storing small amounts (about 1-2% of their own weight) of hydrogen at room temperature.
