Researchers have for the first time determined that hybridization between two bird species can give rise to several novel and fully functional hybrid genomic combinations. This could potentially be because hybrid species emerged through independent hybridization events between the same parent species on different islands.

The proteins PCH1 and PCHL help plants adapt to their surroundings. Plants react sensitively to changes in their surroundings and possess the ability to adapt to them. They use the photoreceptor protein phytochrome B to see light and then regulate processes such as seed germination, seedling development, longitudinal growth and flower formation.

Breakthrough study shows how plants sense the world

Added: 19.01.2018 19:03 | 0 views | 0 comments


Plants lack eyes and ears, but they can still see, hear, smell and respond to environmental cues and dangers. They do this with the aid of hundreds of membrane proteins that sense microbes or other stresses. Researchers now have created the first network map for 200 of these proteins. The map shows how a few key proteins act as master nodes critical for network integrity, and the map also reveals unknown interactions.

Scientists find microbes on the skin of mice promote tissue healing, immunity

Added: 19.01.2018 16:43 | 0 views | 0 comments

#zrodlo

Beneficial bacteria on the skin of lab mice work with the animals' immune systems to defend against disease-causing microbes and accelerate wound healing, according to new research. Researchers say untangling similar mechanisms in humans may improve approaches to managing skin wounds and treating other damaged tissues.

#zrodlo

Artificial biology is working toward creating a genuinely new organism. Researchers are designing and building proteins that can fold and mimic the chemical processes that sustain life. Now they have confirmed that at least one of their new proteins can catalyze biological reactions in E. coli, meaning that a protein designed entirely from scratch functions in cells as a genuine enzyme.

In what is being described as 'The Teddy Roosevelt effect,' a deadly fungus in the Pacific Northwest may have arrived from Brazil via the Panama Canal, according to a new study. Cryptococcus gattii -- which until a 1999 outbreak in British Columbia's Vancouver Island was considered primarily a tropical fungus -- can cause deadly lung and brain infections in both people and animals.

Seasonal flu viruses continually undergo mutations that help them evade the human immune system, but some of these mutations can reduce a virus's potency. According to new research, certain mutations in the genome of influenza A may help counteract the weakening effects of other mutations.

Convergent evolution of gene regulation in humans and mice

Added: 18.01.2018 16:44 | 0 views | 0 comments

#zrodlo

Organisms that aren't closely related may evolve similar traits as they adapt to similar challenges. It's called convergent evolution, and familiar examples include the wings of birds, bats, and insects, and echolocation in bats and dolphins. Now, molecular biologists have found evidence of convergent evolution in an important mechanism of gene regulation in humans and mice.

Around 400 million people world-wide suffer in some form or other from a grass pollen allergy (rhinitis) – with the usual symptoms such as a runny nose, cough and severe breathing problems. Medical researchers have now shown in a Phase II-b study with 180 patients in 11 European centers, that four injections of the synthetically manufactured vaccine BM32 in the first year and a top-up in the second year of treatment relieve the sufferers' symptoms by at least 25%.

Women have many options for oral contraceptives that are safe, effective and reversible, but despite decades of research, men have none. Now, scientists report a rat study that shows they finally have a good lead for a male birth control pill. It's based on ouabain, a plant extract that African warriors and hunters traditionally used as a heart-stopping poison on their arrows.
