New understanding of tumor microenvironment could help enhance immunotherapy

A paper published today in Nature shows how chemicals in the areas surrounding tumors--known as the tumor microenvironment--subvert the immune system and enable cancer to evade attack. These findings suggest that an existing drug could boost cancer immunotherapy.

Study reveals key process by which plants switch between different stress responses

To design effective strategies that protect significant agricultural crops from climate change, it is important to understand how plants react to stressful environmental conditions.

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.

Study may lead to alternative treatment for potentially addictive opioid pain killers

When two naturally occurring lipids are altered using a process called epoxidation, they are transformed into powerful agents that target numerous cannabinoid receptors in neurons, disrupting pathways that promote inflammation and pain.

Scientists identify mystery protein that explains the origins of Parkinson's Disease

Researchers have made a “vital step” toward inferring the origins of Parkinson’s disease—a neurological condition that is rapidly growing in the world.

Manganese is limiting factor for phytoplankton growth in the Southern Ocean

The term plankton describes usually very small organisms that drift with the currents in the seas and oceans.

Changing cropping systems in impaired watersheds can produce water quality gains

Growing the right crop in the right place within an impaired watershed can achieve significant water quality improvements, according to Penn State researchers.

Agricultural activity confuses the mechanisms that regulate occurrence of plant diseases

A study carried out at the University of Helsinki indicates that agricultural activity confuses the mechanisms that regulate the occurrence of plant diseases in nature.

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.

Anchor proteins inhibit a key metabolic driver involved in cancer and neuronal diseases

Certain anchor proteins inhibit a key metabolic driver that plays an important role in cancer and developmental brain disorders.

Study reveals complete genome of major parasitic flowering plant

On January 22 in Current Biology, a team of Harvard-led researchers presented the most complete genome yet assembled of one of the major Rafflesiaceae lineages, Sapria himalayana.

Study: Vegan diet has broad effect on children's metabolism

The study concludes that vegan diet has a broad effect on children's metabolism. Serum biomarker levels for vitamins A and D, cholesterol forms and essential amino acids were significantly lower in children on vegan diet compared to age-adjusted omnivores.

Earth’s largest freshwater lakes reveal carbon fixation trends

NASA-funded research on the 11 largest freshwater lakes in the world coupled field and satellite observations to provide a new understanding of how large bodies of water fix carbon, as well as how a changing climate and lakes interact.

Food choice may accelerate aging and shorten lifespan of fruit flies

Having a choice of foods may accelerate aging and shorten the lifespan of fruit flies, according to a study published today in the open-access eLife journal.

Scientists urge global policymakers to recognize fish as a solution to food insecurity

Scientists are urging global policymakers and funders to think of fish as a solution to food insecurity and malnutrition, and not just as a natural resource that provides income and livelihoods, in a newly-published paper in the peer-reviewed journal Ambio.

Study shows how nonmalignant cells adapt to harsh tumor microenvironment

Cells need energy to survive and thrive. Generally, if oxygen is available, cells will oxidize glucose to carbon dioxide, which is very efficient, much like burning gasoline in your car. However, even in the presence of adequate oxygen, many malignant cells choose instead to ferment glucose to lactic acid, which is a much less efficient process.

Study shows how resilience of the Earth's climate system has changed over time

Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests.

Ethylene allows plant roots to sense and avoid compacted soils

The volatile plant hormone ethylene allows plant roots to sense and avoid compacted soils, researchers report. Rendering roots insensitive to ethylene allowed them to penetrate compacted soils more effectively, the same group showed.

Study: No-till practices can significantly reduce soil erosion rates

Soil erosion is a major challenge in agricultural production. It affects soil quality and carries nutrient sediments that pollute waterways. While soil erosion is a naturally occurring process, agricultural activities such as conventional tilling exacerbate it.

Study reveals richness of space-time gene expression dynamics of the liver

Nothing in biology is static. Biological processes fluctuate over time, and if we are to put together an accurate picture of cells, tissues, organs etc., we have to take into account their temporal patterns. In fact, this effort has given rise to an entire field of study known as "chronobiology".
