Plants may control the genetics of intimate root symbionts

Researchers from the University of Ottawa have discovered that plants may be able to control the genetics of their intimate root symbionts - the organism with which they live in symbiosis - thereby providing a better understanding of their growth.

Researchers explore the regulatory role of protein in human health and disease

Researchers from the University of Virginia, Lehigh University and the Massachusetts Institute of Technology are pooling their respective labs' expertise to unlock the mysteries of a protein that plays a critical regulatory role in human health and disease.

Study provides a causal link between the Alzheimer's risk gene and COVID-19

A City of Hope-led research team found that the same gene that increases the risk for Alzheimer's disease, ApoE4, can increase the susceptibility to and severity of COVID-19.

Scientists identify new drug target for treating Hutchinson-Gilford progeria syndrome

Researchers have discovered a promising treatment method for Hutchinson-Gilford progeria syndrome (HGPS)—a debilitating genetic disorder that accounts for rapid and premature aging in children.

Researchers gain a deep insight into the evolutionary history of bitter receptors

To evaluate the chemical composition of food from a physiological point of view, it is important to know the functions of the receptors that interact with food ingredients. These include receptors for bitter compounds, which first evolved during evolution in bony fishes such as the coelacanth.

Researchers study the formation of reinforced, patterned cell walls during proto-xylem development

Trees are by far the tallest organisms on Earth. Height growth is made possible by a specialized vascular system that conducts water from the roots to the leaves with high efficiency, while simultaneously providing stability.

Breast cancer-on-a-chip for rapid screening of immunotherapeutic drugs

There are many mechanisms by which the body responds to foreign invaders. One of these involves the T-cells of the immune system, which have a number of different proteins on their surface called "checkpoint proteins."

Synthetic biomolecule resembles dual stimuli-responsive channel

For the first time, researchers from the Tokyo Institute of Technology (Tokyo Tech) and the University of Tokyo in Japan have produced a new artificial transmembrane ion channel—based on a naturally found transmembrane channel that plays a role in neuron signaling—that reacts to both electrical and chemical stimuli.

Yale scientists discover novel metabolic gatekeeper mechanism for leukemia

In a new study led by Yale Cancer Center, researchers have discovered a novel metabolic gatekeeper mechanism for leukemia. This mechanism depends on a molecule called PON2, which could lead to a new treatment for the disease. The findings were published online today in the Proceedings of the National Academy of Sciences (PNAS).

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.
