The self-synthesizing ribosome

As the cell's protein factory, the ribosome is the only natural machine that manufactures its own parts. That is why understanding how the machine, itself, is made, could unlock the door to everything from understanding how life develops to designing new methods of drug production.

Tick-borne encephalitis spread across Eurasia with settlers and their pets and prey

Researchers from Sechenov University together with colleagues from several Russian institutes analysed data on the RNA structure of tick-borne encephalitis virus. Much larger than in previous studies, the data volume of the new study allowed them to estimate the age of the virus subtypes and track its spread in Eurasia. The results of the study were published in the journal Viruses.

UBC scientist identifies a gene that controls thinness

Why can some people eat as much as they want, and still stay thin? In a study published today in the journal Cell, Life Sciences Institute Director Dr. Josef Penninger and a team of international colleagues report their discovery that a gene called ALK (Anaplastic Lymphoma Kinase) plays a role in resisting weight gain.

Ultrasonic technique discloses the identity of graphite

A group of researchers, led by Osaka University, created a high-quality defect-free monocrystalline graphite, and measured the elastic constant, demonstrating that the determined value of monocrystalline graphite was above 45 gigapascal (GPa), which was higher than conventionally believed. Applying ultrasonic measurement techniques to this multilayer defect-free monocrystalline graphite thin film...

Weight loss surgery may alter gene expression in fat tissue

New findings published in the Journal of Internal Medicine reveal altered gene expression in fat tissue may help explain why individuals who have regained weight after weight loss surgery still experience benefits such as metabolic improvements and a reduced risk of type 2 diabetes.

Women quotas in politics have unintended consequences

Women continue to be scarce in the halls of power. To rectify this inequality, many countries have imposed female electoral quota systems, or rules designed to increase the representation of women. The catch? Boosting gender may well curtail representation in other respects.

T-cells could be made into better cancer killers by increasing their protein production

Researchers have developed a technique to quantify protein production in immune cells known as T-cells, which typically target and kill cancer cells. However, when near a tumor, most T cells produce little protein and lose their cancer-fighting ability, and the new technique could help clarify why. Interventions could then be developed to restore protein production and allow T cells in the...
