Scientists develop new method to track radical changes in ecosystems

Earth and all the living organisms on it are constantly changing. But is there any way we can detect if these changes are occurring at an abnormal rate? What are the consequences of these changes for the organisms affected?

Gut microbes mitigate radiation exposure, repair GI tract

A new study by scientists at UNC Lineberger Comprehensive Cancer Center and colleagues published Oct. 30, 2020, in Science, showed that mice exposed to potentially lethal levels of total body radiation were protected from radiation damage if they had specific types of bacteria in their gut.

Water quality and deficit irrigation schemes have major effects on crop development

In the driest state in the driest continent in the world, South Australian farmers are acutely aware of the impact of water shortages and drought. So, when it comes to irrigation, knowing which method works best is vital for sustainable crop development.

Climate change is expected to increase mega-droughts, shows research

Mega-droughts - droughts that last two decades or longer - are tipped to increase thanks to climate change, according to University of Queensland-led research.

Study shows statins have different effects on different parts of the body

Contrary to expectation, treatment with statins has a different effect on blood cells than on muscle cells, a new study from the University of Copenhagen reveals.

New type of cancer immunotherapy trains the immune system to eliminate tumor cells

A groundbreaking new type of cancer immunotherapy developed at the Icahn School of Medicine at Mount Sinai trains the innate immune system to help it eliminate tumor cells through the use of nanobiologics, tiny materials bioengineered from natural molecules that are paired with a therapeutic component, according to a study published in Cell in October.

“Nanobiologic” immunotherapy can train the immune system to eliminate tumor cells

Until recently, it was believed that the innate immune system, the body's first line of defense, lacked the ability to remember pathogens like the adaptive immune system.

Reducing food intake can reduce risk of liver cancer caused by fatty liver

Liver cancer from too much fat accumulation in the liver has been increasing in many countries including Japan. In order to change this unfortunate state of affairs, it is important to improve the prognosis of non-alcoholic fatty liver disease.

Study identifies genes and molecular pathways most sensitive to chemical exposures

A University of Massachusetts Amherst environmental health scientist has used an unprecedented objective approach to identify which molecular mechanisms in mammals are the most sensitive to chemical exposures.

Toxins produced by tube-dwelling anemones have pharmacological potential, shows research

Researchers based in Brazil and the United States have completed the first-ever mapping exercise to profile the toxins produced by tube-dwelling anemones, or cerianthids, a family of marine animals belonging to the same phylum (Cnidaria) as sea anemones, jellyfish and corals.

Researchers discover molecular machinery that coordinates cell orientation in tissue

Plants have veins that transport nutrients throughout their whole body. These veins are organized in a highly ordered manner.

Scientists develop novel microcarrier for large-scale cell production

Researchers from Singapore-MIT Alliance for Research and Technology (SMART), MIT's research enterprise in Singapore, have developed a novel microcarrier for large-scale cell production and expansion that offers higher yield and cost-effectiveness compared to traditional methods, and reduces steps required in the cell retrieval process.

Study shows how fear and aggression are regulated

Our brains are wired to protect us from threats. For social animals like humans, threats often come from other members of our own species when there is conflict over food, mates, or territory.

SARS-Cov-2 spike proteins can directly impact the function of blood-brain barrier

Like a key, SARS-CoV-2 - the virus that causes coronavirus disease 2019 (COVID-19) - attaches to specific molecules on the host cell surface, opening gateways into the cell interior.

Human immune system may play a key role in shaping the microbiome composition

The gut is an unusually noisy place, where hundreds of species of bacteria live alongside whatever microbes happen to have hitched a ride in on your lunch.

Researchers find genetic correlations between inflammatory bowel disease and stress, depression

Using sophisticated 3D genomic mapping and integrating with public data resulting from genome-wide association studies (GWAS), researchers at Children's Hospital of Philadelphia (CHOP) have found significant genetic correlations between inflammatory bowel disease (IBD) and stress and depression.

'Training’ the innate immunity may improve the success of immunotherapy

Immunotherapies, such as checkpoint inhibitor drugs, have made worlds of difference for the treatment of cancer. Most clinicians and scientists understand these drugs to act on what's known as the adaptive immune system, the T cells and B cells that respond to specific threats to the body.

Scientists discover new anti-cancer molecule

A group of Moscow scientists has discovered and explained the activity mechanism of a new anti-cancer molecule -- diphenylisoxazole. This molecule has been shown to be effective against human cancer cells. The research, published in the journal Bioorganic & Medicinal Chemistry Letters, makes it possible to produce an affordable cancer treatment drug.
