and does not add stiffness or weight to
the cord and thus does not affect the
dynamics of the parachute or the structural response of the system. The CGauge can be scaled to larger and smaller
sizes to measure larger and smaller load
capabilities, dependent on the cord.

Disease-Sniffing Device Rivals a
Dog's Nose
The miniaturized detector mimics the process dogs use to
detect cancer and other diseases by smell.

rained dogs can detect many kinds of
disease - including lung, breast, bladder, and prostate cancers and possibly
COVID-19 - simply through smell. But it
takes time to train such dogs and their
availability and time is limited. Researchers
have come up with a system that can
detect the chemical and microbial content of an air sample with even greater
sensitivity than a dog's nose. They coupled this to a machine-learning process
that can identify the distinctive characteristics of the disease-bearing samples.
Trained dogs can identify cancers
that don't have any identical biomolecular signatures in common. Using powerful analytical tools - including gas chromatography mass spectrometry (GCMS)
and microbial profiling - if samples from
skin cancer, bladder cancer, breast cancer,
and lung cancer are analyzed, they have
nothing in common, yet dogs can generalize from one kind of cancer to be able to
identify the others.
A miniaturized detector system incorporates mammalian olfactory receptors
stabilized to act as sensors, whose data
streams can be handled in real time by a
typical smartphone's capabilities. Such
detectors, equipped with advanced algorithms developed through machine
learning, could potentially pick up early
signs of disease far sooner than typical
screening regimes and could even warn
of smoke or a gas leak.
The team tested 50 samples of urine
from confirmed cases of prostate cancer
and controls known to be free of the disease, using both trained dogs and the
miniaturized detection system. They applied a machine-learning program to
tease out any similarities and differences
