Restoring the function of a human cell surface protein in yeast cells      (via sciencedaily.com)     Original source 

Yeast cells are widely used to study G protein-coupled receptors (GPCRs), a large group of cell surface proteins in humans. However, several of these proteins lose their function when introduced into yeast cells. To tackle this issue, researchers developed an innovative strategy to restore GPCR function in yeast cells by inducing random mutations. Their findings can help understand GPCRs better and could pave the way to therapeutic breakthroughs for many diseases.

A miniature magnetic resonance imager made of diamond      (via sciencedaily.com)     Original source 

The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now the resolution of conventional imaging methods has not been high enough to represent these processes in detail. A research team has now developed diamond quantum sensors which can be used to improve resolution in magnetic imaging.

New 'subway map' of Lyme disease pathways identifies potential new treatment targets      (via sciencedaily.com)     Original source 

Scientists  have developed a genome-scale metabolic model or 'subway map' of key metabolic activities of the bacterium that causes Lyme disease. Using this map, they have successfully identified two compounds that selectively target routes only used by Lyme disease to infect a host.

Electrical control of quantum phenomenon could improve future electronic devices      (via sciencedaily.com)     Original source 

A new electrical method to conveniently change the direction of electron flow in some quantum materials could have implications for the development of next-generation electronic devices and quantum computers. A team of researchers has developed and demonstrated the method in materials that exhibit the quantum anomalous Hall (QAH) effect -- a phenomenon in which the flow of electrons along the edge of a material does not lose energy.

Pinpointing the emergence of muddy flavors in your fish      (via sciencedaily.com)     Original source 

Many people have experienced a muddy off-flavor in farmed fish. While the aquaculture industry has known about the problem for 20 years, it continues to impact the consumption of otherwise healthy and potentially sustainable fish. Now, researchers have been able to pinpoint exactly when the off-flavors emerge. And this can make it easier to deal with the compounds that turn people away from farmed fish.

Racing to defuse a 'ticking' public health time bomb      (via sciencedaily.com)     Original source 

The explosive rise in tick-borne diseases in many parts of the United States over the last five decades represents a major public health threat that demands innovative solutions, warns a group of scientists. They outline why the stakes are so high and describe some potential solutions. Possible solutions include a new class of vaccines for humans and even for the animals that carry the ticks.

New insights into the genetics of the common octopus: Genome at the chromosome level decoded      (via sciencedaily.com)     Original source 

Octopuses are fascinating animals -- and serve as important model organisms in neuroscience, cognition research and developmental biology. To gain a deeper understanding of their biology and evolutionary history, validated data on the composition of their genome is needed, which has been lacking until now. Scientists have now been able to close this gap and, in a new study, determined impressive figures: 2.8 billion base pairs -- organized in 30 chromosomes. What sounds so simple is the result of complex, computer-assisted genome analyses and comparisons with the genomes of other cephalopod species.

Art with DNA -- Digitally creating 16 million colors by chemistry      (via sciencedaily.com)     Original source 

The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location of imperfect complementary sequences. Fluorescent markers bound to one of the matching DNA strands make the duplex visible, and fluorescence intensity increases with increasing duplex stability. Now, researchers have succeeded in creating fluorescent duplexes that can generate any of 16 million colors -- a work that surpasses the previous 256 colors limitation. This very large palette can be used to 'paint' with DNA and to accurately reproduce any digital image on a miniature 2D surface with 24-bit color depth.

Boosting weak immune system: Scientists find an unusual weapon against virus      (via sciencedaily.com)     Original source 

Infections with cytomegalovirus (CMV) are extremely common and often pose no major threat to the vast majority of people. They can however be deadly for people whose immune system is weakened, e.g., after bone marrow transplantation. Current treatments against CMV infections are very limited and can have severe side effects. Researchers now propose a new way to protect against CMV. Instead of targeting the virus, their approach boosts the weak immune system and lets it fight the virus on its own.
