Dietary anti-cancer compound may work by influence on cellular genetics

Sulforaphane, a dietary compound from broccoli that’s known to help prevent prostate cancer, may work through its influence on long, non-coding RNAs, report scientists. This is another step forward in a compelling new area of study on the underlying genetics of cancer development and progression.

Human antibody for Zika virus promising for treatment, prevention

Researchers have determined the structure of a human antibody bound to the Zika virus, revealing details about how the antibody interferes with the infection mechanism — findings that could aid in development of antiviral medications.

Viruses created to selectively attack tumor cells

It is an innovative approach that takes advantage of the different expression profiles of certain proteins between tumor and healthy cells that make the virus to only infect the first ones.

Discovery of an HIV reservoir marker: New avenue toward eliminating the virus

A marker has been identified that makes it possible to differentiate “dormant” HIV-infected cells from healthy cells. This discovery will make it possible to isolate and analyze reservoir cells which, by silently hosting the virus, are responsible for its persistence even among patients receiving antiviral treatment, whose viral load is undetectable, say scientists.

How plankton cope with turbulence

Microscopic marine plankton are not helplessly adrift in the ocean. They can perceive cues that indicate turbulence, rapidly respond to regulate their behavior and actively adapt. Researchers have demonstrated for the first time how they do this.

Biochemists develop new way to control cell biology with light

Researchers have developed a new method of controlling biology at the cellular level using light. The tool — called a photocleavable protein — breaks into two pieces when exposed to light, allowing scientists to study and manipulate activity inside cells in new and different ways.

With climate change, shrubs and trees expand northwards in the Subarctic

Shrubs expand in the tundra in northern Scandinavia. And it is known that fixation of nitrogen from the air is in the tundra to a high degree performed by cyanobacteria associated with mosses. Also enhanced nitrogen fixation stimulates plant growth. New research shows that as taller shrubs expand into the tundra, nutrients in their leaf litter will either promote or reduce the nitrogen fixation, depending upon which shrub species that will dominate.

Overuse of antibiotics brings risks for bees, and for us

Honeybees treated with a common antibiotic were half as likely to survive the week after treatment compared with a group of untreated bees, a finding that may have health implications for bees and people alike.

Zebrafish without stripes

Dowling-Degos disease is a hereditary pigmentation disorder that generally progresses harmlessly. However, some of those affected also develop severe skin inflammation. An international team of researchers has now found a cause for this link. Their knowledge comes thanks to an animal that is known among aquarium owners for its characteristic pigmentation: the zebrafish.
