Researchers find immune component to rare neurodegenerative disease

Posted: 21 Jul 2021 02:27 PM PDT

Researchers have identified an immune protein tied to the rare neurodegenerative condition known as Niemann-Pick disease type C. The finding, made in mouse models, could offer a powerful new therapeutic target for Niemann-Pick disease type C, a condition that was identified more than a century ago but still lacks effective treatments.

Kids eat more fruit and vegetables with longer seated lunch time

Posted: 21 Jul 2021 11:19 AM PDT

When kids sit down to eat lunch at school, fruits and vegetables may not be their first choice. But with more time at the lunch table, they are more likely to pick up those healthy foods. If we want to improve children's nutrition and health, ensuring longer school lunch breaks can help achieve those goals, according to new research.

Why weren't New World rabbits domesticated?

Rabbits were raised for over a thousand years in Mexico without becoming domesticated. A new study finds that their solitary lifestyle and greater species diversity made domestication unlikely.

Unexpected proteome plasticity in response to persistent temperature rise

Posted: 21 Jul 2021 11:19 AM PDT

Common yeast are able to adapt and thrive in response to a long-term rise in temperature by changing the shape, location and function of some of their proteins. The surprising findings demonstrate the unappreciated plasticity in the molecular and conformational level of proteins and bring the power of molecular biology to the organismal response to climate change.

Chromosomes separation under focus

Posted: 21 Jul 2021 11:19 AM PDT

During cell division, chromosomes are duplicated and separated so that one copy of each chromosome is inherited by each of the two emerging daughter cells. Correct distribution of chromosomes requires high accuracy and defects in this process can cause aberrant distribution of chromosomes and facilitate cancer development. By analyzing the structure of the protein responsible for chromosome separation, a team has shed light on the mechanisms controlling this essential player in cell division.

Genome editing meets marsupials

Researchers at RIKEN, Japan have succeeded in creating the first genetically engineered marsupial. This study will contribute to deciphering the genetic background of unique characteristics observed only in marsupials.

Who eats the invaders?

A landmark study documenting instances where native Mediterranean species have preyed upon two highly invasive marine fish -- the Pacific red lionfish and the silver-cheeked toadfish -- has just been published.

Fully booked at the bottom of the sea: There seems no room for new bacteria on sand grains

Posted: 21 Jul 2021 07:23 AM PDT

Whether summer or winter, midnight sun or polar night, the sand on the ocean floor is always inhabited by the same bacteria. Although the microbial communities differ between different ocean regions, they do not change between the seasons. Presumably, there is simply no room for change. Researchers now describe this phenomenon in a new study.

Blocking how the malaria parasite suppresses the immune response

The parasites that cause severe malaria are well-known for the sinister ways they infect humans, but new research may lead to drugs that could block one of their most reliable weapons: interference with the immune response.

Tiny organisms shed big light on ocean nutrients

Posted: 21 Jul 2021 07:23 AM PDT

Sweeping changes in marine nutrients may seem to be a likely consequence of increasing global temperatures; however, new research suggests that processes below the ocean surface could play a larger role than previously thought.

New tool differentiates endangered salt marsh harvest mouse from abundant look-alike
