Malaria: New knowledge about naturally acquired immunity may improve vaccines

Added: 13.11.2021 16:20 | 262 views | 0 comments

When you have become immune to malaria after having contracted the disease, it seems that the body uses a more efficient protection than if you have been vaccinated against the deadly disease. The researchers believe the new findings may be used to improve existing malaria vaccines.

Obesity raises the risk of gum disease by inflating growth of bone-destroying cells

Added: 13.11.2021 16:20 | 255 views | 0 comments

Chronic inflammation caused by obesity may trigger the development of cells that break down bone tissue, including the bone that holds teeth in place, according to new research that sought to improve understanding of the connection between obesity and gum disease. The study, completed in an animal model and published in October in the Journal of Dental Research, found that excessive inflammation resulting from obesity raises the number of myeloid-derived suppressor cells (MDSC), a group of immune cells that increase during illness to regulate immune function. MDSCs, which originate in the bone marrow, develop into a range of different cell types, including osteoclasts (a cell that breaks down bone tissue).

It takes more than one mutant copy of the PIK3CA gene to make breast cancer more aggressive, study finds

Added: 13.11.2021 16:20 | 261 views | 0 comments

Breast cancers that have an overactive PI3K enzyme tend to be more aggressive and to spread and divide more like stem cells. But a new study uncovers a surprising relationship between PI3K activity and mutations in the PIK3CA gene that codes for the enzyme.

The mechanism behind one of the first stages of coal creation may not be what we thought it was, according to a team of researchers who found that microbes were responsible for coal formation and production of methane in these areas, which has implications for methane fuel recovery from some coal fields.

Unstable housing, homelessness associated with COVID-19 re-infection

Added: 13.11.2021 16:20 | 252 views | 0 comments

New study results demonstrate that unstable housing and homelessness is associated with a two-fold greater chance of being re-infected with SARS-CoV-2 compared to those who are securely housed. The research indicates that unstable housing was the only demographical factor associated with re-infection despite the presence of antibodies from the first infection.

Sea urchins' ballistic escape from predators

Added: 13.11.2021 16:20 | 249 views | 0 comments

New research shows that sea urchins, albeit having a limited and ancestral sensory system, can show a complex behaviour when escaping a predator. These marine invertebrates tend to move slowly and with unpredictable movements, but when they smell a predator, they escape following a ballistic motion -- straightforward, quick and directional -- to escape the threat.

Amazon Rainforest birds’ bodies transform due to climate change

Added: 13.11.2021 12:25 | 258 views | 0 comments

The most pristine parts of the Amazon rainforest devoid of direct human contact are being impacted by human-induced climate change, according to new research. New analyses of data collected over the past four decades show that not only has the number of sensitive resident birds throughout the Amazon rainforest declined, but the body size and wing length have changed for most studied species. These physical changes in the birds track increasingly hot and dry conditions in the dry season, from June to November.

For stem cells, bigger doesn’t mean better

Added: 13.11.2021 12:25 | 231 views | 0 comments

A new study suggests that enlargement of stem cells contributes to age-related decline in function. The researchers found that blood stem cells, which are among the smallest cells in the body, lose their ability to perform their normal function -- replenishing the body's blood cells -- as they grow larger. When the cells were restored to their usual size, they behaved normally again.

Ancient Indigenous fishing practices can be used to inform sustainable management and conservation today, according to a new study. Working with the Tsleil-Waututh Nation and using new palaeogenetic analytical techniques, the results of a new study provides strong evidence that prior to European colonization, Coast Salish people were managing chum salmon by selectively harvesting males.
