Healthy Diet Index supports diet quality assessment and dietary counselling in healthcare

The Healthy Diet Index is a tool developed by Finnish nutrition experts to assess diet quality. It was found to associate with the intake of energy nutrients, fibre, and several vitamins and minerals, and to be linked to lower body mass index, waist circumference, and blood glucose levels in both men and women.

Cheaper carbon capture is on the way

A new solvent, EEMPA, has been developed that captures carbon dioxide at a cost of $47.10 per metric ton, surpassing commercial technology's $58.30 per metric ton. The solvent is water-lean and 99% less viscous than previous formulations, allowing it to be easily applied in existing capture systems.

After cracking the "sum of cubes" puzzle for 42, researchers discover a new solution for 3

After solving the sum of cubes puzzle for 42, researchers found a new solution for 3 using an optimized algorithm that utilized mathematical 'sieving' techniques. The discovery suggests there may be infinitely many more solutions for other values of k, with the next solution involving gigantic 21-digit numbers.

Simultaneous multicontrast OR-PAM from single laser source

Researchers developed a multiwavelength OR-PAM system based on a single laser source, enabling simultaneous multicontrast imaging of hemoglobin concentration, blood flow speed, blood oxygen saturation, and lymphatic concentration. This innovation shortens imaging time and improves accuracy for functional imaging in biological tissues.

Deforestation favors an increase in the diversity of antibiotic-resistant soil bacteria

A study found that deforestation in the Amazon leads to an increase in antibiotic-resistant soil bacteria, with a larger number of genes and molecular mechanisms detected in deforested areas than in forested ones. The researchers warn that these microorganisms can pose a significant public health risk if they reach humans.

Capturing all of light's data in one snapshot

Researchers at Duke University and other institutions are developing a 'super camera' capable of capturing all types of information carried by light, including polarization, depth, phase, coherence, and incidence angle. The project aims to create an imaging system that can handle sensing and processing simultaneously, streamlining size...

Researchers boost potency of an HIV-1 antibody, tracing new pathways for vaccine development

Scientists have identified a promising antibody that can effectively fight HIV-1 by tracing new pathways for vaccine development. The study found that the binding strength of the antibody is directly correlated to its ability to neutralize HIV-1, and researchers discovered genetic mutations that enhance the antibody's potency against d...

New clinical method could lower risk of recurring heart attacks

Researchers at Lund University developed a new examination method using NIRS and IVUS, which identifies high-risk plaques that cannot be seen with traditional angiograms. The study found that over 14% of treated patients experienced heart disease recurrence within four years, highlighting the importance of early detection and treatment.
