Good vibrations?

Researchers have found that exposure to vibrations from power tools can cause hand-arm vibration syndrome, a condition that leads to numbness, loss of dexterity, and discoloration in the extremities. A study by Concordia engineer Subhash Rakheja suggests that simple seat upgrades can reduce exposure by up to 60 percent.

Charge it: Neutral atoms made to act like electrically charged particles

Researchers from NIST have created a new method to make neutral atoms behave as if they are charged particles in an electric field. This allows for the simulation and study of fundamental electrical phenomena, including superconductivity and the quantum Hall effect. The synthetic electric fields mimic the behavior of charged particles ...

Getting the point: Real-time monitoring of atomic-microscope probes adjusts for wear

Scientists at NIST have developed a method to measure the wear and degradation of AFM tips in real time, allowing for dramatic improvements in precision and speed. This technique uses contact resonance force microscopy to track the resonant frequency of the sensor tip, enabling atomic-scale resolution and reducing inaccuracies.

New therapeutic target for lung cancer

A new therapeutic target for lung cancer has been identified by researchers at Seoul National University. The variant of the protein AIMP2 is highly expressed in lung cancer cells and has been shown to compromise the tumor-suppressing activity of AIMP2, suggesting its potential as a new treatment option.

A measurement first: NIST 'noise thermometry' system measures Boltzmann Constant

Researchers at NIST have developed an electronic technique called Johnson noise thermometry to measure the Boltzmann constant with an uncertainty of 12 ppm. This method has the potential to advance international efforts to revamp the world's scientific measurement system, enabling more precise definitions of units like the Kelvin.

Blood simple circuitry for cyborgs

Researchers developed a biological memristor using human blood, exhibiting memory effects when exposed to voltage polarity and magnitude. The breakthrough demonstrates the potential for creating liquid memristors from human tissues, paving the way for future cyborg devices.

Could HIV-infected organs save lives?

Researchers estimate that lifting the ban on HIV-infected organ donation could provide transplants to 500 patients annually. The study suggests that this change would not only benefit HIV-positive patients but also reduce waiting times for non-HIV infected patients.

Educational development stunted by teenage fatherhood

A new study found that teenage fatherhood significantly impacts young adult outcomes, including a 15-point reduction in high school graduation rates and an 11-point increase in receiving a GED. The experience of teenage fatherhood also increases the likelihood of full-time employment and military service.
