Scientists successfully increase measurement rate of Raman spectroscopy by 100-fold

Researchers Takuma Nakamura, Kazuki Hashimoto, and Takuro Ideguchi of the Institute for Photon Science and Technology at the University of Tokyo have increased by 100-fold the measurement rate of Raman spectroscopy, a common technique for measuring the “vibrational fingerprint” of molecules in order to identify them.

As the measurement rate has been a major limiting factor, this improvement contributes to advancements in many fields that rely on identifying molecules and cells, such as biomedical diagnostics and material analytics. The findings were published in the journal Ultrafast Science.

Identifying various types of molecules and cells is a crucial step in both basic and applied science. Raman spectroscopy is a widely used measurement technique for this purpose. When a is projected onto molecules, the light interacts with the vibrations and rotations of molecular bonds, shifting the frequency of the scattering light. The scattering spectra thus measured is a molecule’s unique “vibrational fingerprint.”

Future Medicine: Physics, Biology, And AI Will Transform Human Health

Co-written by Chuck Brooks and Dr. Thomas A. Cellucci, MBA

Verticals that will be most impacted by innovative developments in technology and science are the disciplines of medicine, biotechnology, and health. Those industry verticals will see a profound growth of technological innovation in the near future.

Twenty years ago, Craig Venter and Daniel Cohen remarked, “If the 20th century was the century of physics, the 21st century will be the century of biology.” Since then, there have been some amazing advances in the fields of biotechnology and bioscience, with the promise of even more astounding breakthroughs to come. Over the past decade, we have seen significant strides in artificial intelligence, with radical long-term implications for every human endeavor. And now the convergence of the fields of physics, biology, and AI promises a far greater impact on humanity than any one of these fields alone. Even though a path to successfully integrating these fields exists, it is neither easy nor clear cut—but if done correctly, will revolutionize medicine and human health.

Cancer study finds nuts could hold key to stopping spread of disease

New research has found that a mineral found in Brazil nuts could be the key to stopping the spread of triple negative breast cancer.

Triple negative breast cancer can be hard to treat but is often manageable through therapy and surgery, unless it spreads to other parts of the body when it can become inoperable.

The study, funded by Cancer Research UK, suggests that limiting the antioxidant effects of selenium, a popular ingredient of multivitamin supplements found in everyday foods such as nuts, meat, mushrooms and cereals, could be the secret to controlling this form of the disease.

‘Squeezing’ Increased Accuracy of Quantum Measurements

Tohoku University’s Dr. Le Bin Ho has explored how quantum squeezing can improve measurement precision in complex quantum systems, with potential applications in quantum sensing, imaging, and radar technologies. These findings may lead to advancements in areas like GPS accuracy and early disease detection through more sensitive biosensors.

Quantum squeezing is a concept in quantum physics where the uncertainty in one aspect of a system is reduced while the uncertainty in another related aspect is increased. Imagine squeezing a round balloon filled with air. In its normal state, the balloon is perfectly spherical. When you squeeze one side, it gets flattened and stretched out in the other direction. This represents what is happening in a squeezed quantum state: you are reducing the uncertainty (or noise) in one quantity, like position, but in doing so, you increase the uncertainty in another quantity, like momentum. However, the total uncertainty remains the same, since you are just redistributing it between the two. Even though the overall uncertainty remains the same, this ‘squeezing’ allows you to measure one of those variables with much greater precision than before.

This technique has already been used to improve the accuracy of measurements in situations where only one variable needs to be precisely measured, such as in improving the precision of atomic clocks. However, using squeezing in cases where multiple factors need to be measured simultaneously, such as an object’s position and momentum, is much more challenging.
