Broccoli consumption protects gut lining, reduces disease, in mice      (via sciencedaily.com)     Original source 

Broccoli is known to be beneficial to our health. For example, research has shown that increased consumption of the cruciferous vegetable decreases incidence of cancer and type 2 diabetes. In a recent study, researchers found that broccoli contains certain molecules that bind to a receptor within mice and help to protect the lining of the small intestine, thereby inhibiting the development of disease. The findings lend support to the idea that broccoli truly is a 'superfood.'

Blind dating in bacteria evolution      (via sciencedaily.com)     Original source 

A team of researchers reconstructed long-extinct proteins of a UV protection system of cyanobacteria. The surprising result: the proteins were already compatible with each other when they first met. This discovery expands the knowledge horizon on the rules of evolution.

Researchers create embryo-like structures from monkey embryonic stem cells      (via sciencedaily.com)     Original source 

Human embryo development and early organ formation remain largely unexplored due to ethical issues surrounding the use of embryos for research as well as limited availability of materials to study. Investigators now report on the creation of embryo-like structures from monkey embryonic stem cells. The investigators also transferred these embryo-like structures into the uteruses of female monkeys and determined that the structures were able to implant and elicit a hormonal response similar to pregnancy.

Activating adult-born neurons through deep brain stimulation alleviates Alzheimer's symptoms in rodent models      (via sciencedaily.com)     Original source 

People with Alzheimer's disease develop defects in cognitive functions like memory as well as problems with noncognitive functions that can lead to anxiety and depression. Investigators used mice to study a process through which new neurons are generated in adulthood, called adult hippocampus neurogenesis (AHN). The research showed that deep brain stimulation of new neurons helped restore both cognitive and noncognitive functions in mouse models of Alzheimer's disease.

Complex assembly process involved in DNA virus replication      (via sciencedaily.com)     Original source 

In a twist on the question, 'Which came first, the chicken or the egg?', scientists have long faced a similar question about how human adenovirus replicates: 'Which comes first, assembly of the viral particle, or packaging of the viral genome?' Now, in a new study, scientists have answered that question, showing that viral proteins use a process called phase separation to coordinate production of viral progeny.

How were amino acids, one of the key building blocks of life, formed before the origin of life on Earth?      (via sciencedaily.com)     Original source 

The amino acid abundances of two Ryugu particles were measured and compared with their rocky components. The results demonstrate the important role that water plays in the formation of amino acids on the giant precursors of asteroids like Ryugu. Our solar system formed from a molecular cloud, which was composed of gas and dust that was emitted into the interstellar medium (ISM), a vast space between stars. On collapse of the molecular cloud, the early sun was formed, with a large disk of gas and dust orbiting it. The dusty material collided to produce rocky material that would eventually grow in size to give large bodies called planetesimals.

A miniature heart in a petri dish: Organoid emulates development of the human heart      (via sciencedaily.com)     Original source 

A team has induced stem cells to emulate the development of the human heart. The result is a sort of 'mini-heart' known as an organoid. It will permit the study of the earliest development phase of our heart and facilitate research on diseases.

DELLA proteins could hold key to the next Green Revolution      (via sciencedaily.com)     Original source 

A family of 'promiscuous' proteins found in all land plants is responsible for many different plant functions, despite remaining relatively unchanged for over 450 million years.

Cells refine palm fat into olive oil      (via sciencedaily.com)     Original source 

For more than 50 years, it has been suspected that fat cells constantly remodel the lipids they store. Researchers have now demonstrated this process directly for the first time using culture cells. Among other things, the study shows that the cells quickly eliminate harmful fatty acids. They refine others into molecules that can be used more effectively. In the long term, this turns the components of palm fat into the building blocks of high-quality olive oil, for example.

Cold is beneficial for healthy aging, at least in animals      (via sciencedaily.com)     Original source 

A lower body temperature is one of the most effective mechanisms to prolong the lifespan of animals. New research has now described precisely how this works. The scientists show that cold can prevent the pathological aggregation of proteins typical for two aging-associated neurodegenerative diseases.
