For almost 60 years, measuring cholesterol levels in the blood has been the best way to identify individuals at high risk of cardiovascular disease. In a new study, led by Chalmers University of Technology in Sweden and Harvard University in the USA, researchers have shown comprehensively that a…

Viewing organs in 3D | ScienceDaily
It is now possible to obtain three-dimensional, high-resolution images of enzyme activity in tissue samples or whole organs — thanks to probe molecules that anchor fluorescent dyes within tissue as they are activated by enzymes. The organ being mapped is made transparent by a clearing process….

New AI model improves MS diagnostics
To provide the right treatment for MS, it is important to know when the disease changes from relapsing-remitting to secondary progressive, a transition that is currently recognised on average three years too late. Researchers at Uppsala University have now developed an AI model that can…

Cell colonies under pressure: How growth can prevent motion
The interaction between growth and the active migration of cells plays a crucial role in the spatial mixing of growing cell colonies. This connection was discovered by scientists from the Department of Living Matter Physics at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS)….

Drug combination reduces breast cancer risk and improves metabolic health in rats
Approximately 25% of women in the United States between ages 45 and 60 are at high risk for breast cancer and should consider preventative medication, such as the commonly prescribed drug tamoxifen.
Unfortunately, tamoxifen can cause side effects, including an increased risk for type 2 diabetes…

United States sees disproportionate increase in body mass index rates of more than 60
In the past 20 years, the average rate of obesity among adults in the United States has risen by approximately 30 percent, but the rate of those with the most severe forms of obesity, or those with a body mass index, or BMI, of more than 60 kg/m2, increased by 210 percent. In a recently…

Natural killer cells remember and effectively target ovarian cancer
Researchers at Karolinska Institutet have uncovered a unique ability of a special subtype of natural killer cells in the immune system, called adaptive NK cells, to remember ovarian tumours and effectively attack them. The discovery, published in Cancer Immunology Research, could pave the way…

Gene circuits enable more precise control of gene therapy
Many diseases are caused by a missing or defective copy of a single gene. For decades, scientists have been working on gene therapy treatments that could cure such diseases by delivering a new copy of the missing genes to the affected cells.
Despite those efforts, very few gene therapy…
