Scientists have determined how the body responds during times of emergency when it needs more blood cells. When tissue damage occurs, in times of excessive bleeding, or during pregnancy, a secondary, emergency blood-formation system is activated in the spleen.
Researchers have discovered the negative impact a high fat diet has on red blood cells and how these cells, in turn, promote the development of cardiovascular disease.
Researchers demonstrate a commercially feasible way to use RNA to turn the CRISPR-Cas9 gene editing system on and off as desired -- permanently editing a gene, but only temporarily activating CRISPR-Cas9.
Cetuximab, marketed as Erbitux, is one of the key therapies for metastatic colorectal cancer. Yet the cancer still returns in some patients, shortening overall survival. New research reveals insight into how key proteins, known as epidermal growth factor receptors (EGFR), are regulated, leading to resistance.
Men with prostate cancer who are undergoing radiation therapy can benefit from yoga, researchers reported.
Photosynthesis is the process by which plants, algae and select bacteria transform the sun's energy into chemical energy. But these organisms activate other biochemical pathways at night, when they generate energy by breaking down the sugars that they created during the day. New work focused on this nighttime growth found a protein that is necessary for it to occur and, surprisingly, this protein was also linked to the construction of the plant's cellular membranes.
Scientists have discovered that human brains exhibit more plasticity, propensity to be modeled by the environment, than chimpanzee brains and that this may have accounted for part of human evolution.
Redundancy is common in nature, for example many human genes exist in several copies. However, excessive redundancy can interfere with efficiency. Therefore, each whole genome duplication event is followed by the loss of duplicate genes. A new computational tool and mathematical model opens ways for further discoveries in animal genome evolution, report scientists in a new report.
A new drug has been found to heal eyes in two days after corneal surgery. Originally created in France for chronic diabetic skin wounds, the heparin sulfate mimetic Cacicol (or RGTA) helps eyes heal faster by stimulating collagen production.
Researchers have revealed how a jellyfish -- those commonplace sea pests with stinging tentacles -- have evolved over time into 'really weird' microscopic organisms, made of only a few cells, that live inside other animals.
A new analysis of the jaw of one of the earliest known proto-mammals sheds light on efforts to accurately date the period when mammals first evolved and clarifies the mammalian family tree. The study suggests that the great explosion in mammal diversification occurred in the Jurassic around 175 million years ago -- more than 30 million years after the forerunners to mammals diversified in the Triassic.
Lowering body temperature increases survival, brain function in cardiac arrest patients with non-shockable heart rhythms
Lowering the body's temperature in cardiac arrest patients with 'non-shockable' heart rhythms increases survival and brain function. Patients who received the treatment were about three times more likely to survive cardiac arrest and have better neurological function compared to those who did not receive it.
Drinking coffee daily was associated with a lower risk of deaths from Type 2 diabetes, cardiovascular diseases, and neurological diseases in nonsmokers. Regular consumption of coffee can be included as part of a healthy, balanced diet.
New insights into what nutrients fat cells metabolize to make fatty acids have been released by scientists. The findings pave the way for understanding potential irregularities in fat cell metabolism that occur in patients with diabetes and obesity and could lead to new treatments for these conditions.
The microenvironment of a tumor cell has significant impact on cancer metastasis, new research shows. This discovery has focused attention on fighting cancer in the tumor cell's microenvironment.
Men who are overweight are just as likely as overweight women to experience interpersonal discrimination when applying for a job or shopping at retail stores, according to new research.
A new research study supports the commonly held view that people from disadvantaged groups are using the Internet to broaden their social networks. Those who are from racially or educationally advantaged groups depend more on face-to-face interactions and use the Internet to reinforce their connections with others.
The creation and sustainment of 'safe spaces' may play a critical role in community-based HIV prevention efforts by providing social support and reducing environmental barriers for vulnerable populations, a new study has found.
In order to roost upside down on cave ceilings or tree limbs, bats need to perform an aerobatic feat unlike anything else in the animal world. Researchers have shown that it's the extra mass in bats' beefy wings that makes the maneuver possible.
Once people reach a conclusion, they aren’t likely to change their minds, even when new information shows their initial belief is likely wrong and clinging to that belief costs real money, new research shows.
