Stiffness and viscosity of cells found to differ in cancer and other diseases
During illness, the stiffness or viscosity of cells can change. Tom Evers demonstrated this by measuring such properties of human immune cells for the first time. "The stiffness of certain cells could be a way to make a diagnosis," Evers said......»»
How the Brain Summons Deep Sleep to Speed Healing
A heart attack unleashes immune cells that stimulate neurons in the brain, leading to restorative slumber.....»»
Human histones show promise in fighting bacterial infections
Antibiotics have saved millions of lives from infectious diseases and are considered one of the most important discoveries of the 20th century. However, as the use (and abuse) of antibiotics has increased over the years, many bacteria have developed.....»»
Researchers challenge longstanding theories in cellular reprogramming
A team led by researchers at the University of Toronto has discovered that a group of cells located in the skin and other areas of the body, called neural crest stem cells, are the source of reprogrammed neurons found by other researchers......»»
Imaging advance creates clearer picture of organic solar cells" molecular structure
Research on organic solar cells has been conducted for a long time. Recent advancements in understanding their molecular structures are now paving the way for the development of highly efficient solar cells......»»
Mathematical model decodes protein interactions to show how condensates form
Biological cells are incredibly complex mixes of proteins, nucleic acids, lipids and carbohydrates. A model developed by two RIKEN researchers helps explain why components of the same type sometimes do and sometimes don't spontaneously come together.....»»
Single-molecule tracking technology streamlines drug discovery
New drug discovery is a critical step for improving patients' lives. First, researchers must identify molecules in the body's cells that help drive disease, as these are potential targets for new drugs. The next step is to screen candidate drugs that.....»»
Experiments demonstrate precise delivery of nanoparticles to lung via caveolae pumping system
In recent years, bio-medical engineers have been developing promising techniques that could help diagnose diseases or precisely target specific regions inside the human body. Among these promising therapeutic strategies are methods that rely on the u.....»»
Algae-jellyfish relationship provides insight on immune health
Marine animals like jellyfish, corals and sea anemones often live with algae inside their cells in a symbiotic relationship. The animals give the algae nutrients and a place to live; in return, algae give the animals some of the food they make from s.....»»
Prolonged brain development of marmosets could serve as model for human evolution
The development of primate brains is shaped by various inputs. However, these inputs differ between independent breeders, such as great apes, and cooperative breeders, such as the common marmoset (Callithrix jacchus) and humans. In these species, gro.....»»
Solar-powered animal cells: Combining chloroplasts from algae with hamster cells
Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining chloroplasts (chlorophyll containing structures in.....»»
Compact in-incubator imaging device allows real-time remote monitoring of cell growth
Unlike most cells in the human body, stem cells have the unique ability to divide indefinitely. This property makes them especially appealing to scientists exploring ways to extend human lifespans or develop new methods for repairing damaged tissues......»»
Study finds key protein aids nutrient transport within plant cells
Botanists have come to understand the channels and transporters involved in the uptake and transport of nutrients, yet how are they positioned where they need to be?.....»»
Glycans can regulate their own biosynthesis by modifying enzyme activity
Glycans are chains of sugars that attach to cells through proteins or lipids, changing their chemical characteristics. Glycans can be incredibly complex and branched in structure, contributing to the stability of the extracellular domain of cells and.....»»
What animal societies can teach us about aging
Red deer may become less sociable as they grow old to reduce the risk of picking up diseases, while older house sparrows seem to have fewer social interactions as their peers die off, according to new research showing that humans are not the only ani.....»»
Investigating the flow of fluids with non-monotonic, "S-shaped" rheology
Water and oil, and some other simple fluids, respond in the same way to all levels of shear stress. These are termed Newtonian fluids, and their viscosity is constant for all stresses although it will vary with temperature. Under different stresses a.....»»
New insights into cancer risks from chemicals in fire smoke
Derek Urwin has a special stake in his work as a cancer control researcher. After undergraduate studies in applied mathematics at UCLA, he became a firefighter. His inspiration to launch a second career as a scientist was the loss of his brother, Isa.....»»
How Society’s Beauty Standards Could Impact Breast Cancer Outcomes
An epidemiologist explores a troubling rise in early-onset breast cancer diagnoses and discusses the potential link to chronic exposure to endocrine disruptors......»»
The Forgotten Developer of Tamoxifen, a Lifesaving Breast Cancer Therapy
Her name was on the patent for tamoxifen, but Dora Richardson’s story was lost until now.....»»
