Tiny population of neurons may play a significant role in depression

A tiny population of neurons known to be important to appetite appear to also have a significant role in depression that results from unpredictable, chronic stress, scientists say.

Enzyme in fruit fly larvae plays key role in waking up brain stem cells

Researchers studying an enzyme in fruit fly larvae have found that it plays an important role in waking up brain stem cells from their dormant 'quiescent' state, enabling them to proliferate and generate new neurons.

Rebuilding soil microbiomes becomes challenging in high- tunnel soils with salt and nitrogen

The presence of high salt and nitrogen concentrations in high- tunnel soils may make it more challenging to rebuild a healthy soil microbiome following a soil-clearing event, according to microbial ecologists in Penn State's College of Agricultural Sciences.

Researchers identify tumor suppressor gene involved in stress response

Even the larvae of the Drosophila fly contain adult progenitor cells. And these cells are the only ones that are preserved throughout the growth and are responsible for the development of adult tissues and organs.

Researchers produce microalgae biomass with high content of carotenoid pigments

Scientists from Peter the Great St. Petersburg Polytechnic University (SPbPU) have successfully produced microalgae biomass that has a high content of carotenoid pigments, which is suitable for the food sector.

Ancestral backgrounds can influence Alzheimer's disease risk, finds study

Genetics contributes to the risk of developing Alzheimer's disease, and the APOE gene is the strongest genetic risk factor, specifically the APOE4 allele.

Cancer survivors face barriers in maintaining a healthy diet

New research and analysis appearing in the Journal of the Academy of Nutrition and Dietetics, published by Elsevier, highlights the barriers cancer survivors face in maintaining a healthy diet, as well as the role nutrition may play in cancer risk and treatment.

Unknown root trait allows some cereal plants to grow deeper roots

A previously unknown root trait allows some cereal plants to grow deeper roots capable of punching through dry, hard, compacted soils, according to Penn State researchers, who suggest that harnessing the inherited characteristic could lead to crops better able to deal with a changing climate.

Some bacteria change their shape to become more adaptive to antibiotics

New research led by Carnegie Mellon University Assistant Professor of Physics Shiladitya Banerjee demonstrates how certain types of bacteria can adapt to long-term exposure to antibiotics by changing their shape.

Scientists identify specific genes associated with post-traumatic stress disorder

A research team has found 18 specific, fixed positions on chromosomes (called loci) that seem to be linked to post-traumatic stress disorder (PTSD).

Ocean acidification could be affecting lobsters on a molecular scale

The American lobster, which supports the most valuable fishery in North America, maybe more susceptible to the effects of climate change than previously thought, according to a new study published in Ecology and Evolution.

Study shows why obese mothers tend to have children susceptible to metabolic diseases

A Brazilian study published in the journal Molecular Human Reproduction helps understand why obese mothers tend to have children with a propensity to develop the metabolic disease during their lifetime, as suggested by previous research.

New variant of CRISPR-Cas9 tool expands genomic editing in plants

For the first time, Yiping Qi has represented the College of Agriculture & Natural Resources on the Web of Science 2020 list of Highly Cited Researchers.

New method shows how pharmaceuticals induce cancer cell death

Cancer cells are smart when it comes to anti-cancer drugs, evolving and becoming resistant to even the strongest chemotherapies over time.

Targeting RNA splicing can trigger antiviral immune pathways in triple-negative breast cancers

Researchers at Baylor College of Medicine have discovered how therapeutics targeting RNA splicing can activate antiviral immune pathways in triple negative breast cancers (TNBC) to trigger tumor cell death and signal the body's immune response.

Circadian rhythms control killer cells in the immune system

According to an analysis of data humans’ ability to combat diseases may largely depend on day-to-day circadian cycles than previously believed.

Metabolites may be predictive indicators for recurrent major depressive disorder

Researchers at University of California San Diego School of Medicine, in collaboration with Dutch scientists, have found that certain metabolites -- small molecules produced by the process of metabolism -- may be predictive indicators for persons at risk for recurrent major depressive disorder.

Finding ways to cultivate plants more efficiently in space

When in space, astronauts typically eat dehydrated, nutrient-dense food, but when it comes to longer space missions, that can become a problem as they'll eventually lack nutrients from fresh vegetables.

Scientists trace back evolutionary history of antibiotic resistance genes

By comparing thousands of bacterial genomes, scientists in Gothenburg, Sweden have traced back the evolutionary history of antibiotic resistance genes. In almost all cases where an origin could be determined, the gene started to spread from bacteria that, themselves, can cause disease.
