Nobel laureates Drs. Francis Crick and James Watson’s first model of DNA is shown as a rigid double helix. However, the model is a stiff snapshot of idealized DNA. As researchers now note, DNA is not stiff or static. It is dynamic with high energy existing naturally in a slightly underwound state and its status [...]

A flavonoid derived from citrus fruit has shown tremendous promise for preventing weight gain and other signs of metabolic syndrome which can lead to type 2 Diabetes and increased risk of cardiovascular disease. The study looked at a flavonoid (plant-based bioactive molecule) called naringenin.

By observing the global flow of news online, computer scientists have managed to track and analyze the “news cycle” — the way stories rise and fall in popularity.
People with pain in the elbow or forearm from playing sports or just from common everyday activities, might be able to use a simple bar and strengthening exercise to alleviate pain.

When cells experiencing DNA damage fail to repair themselves, they send a signal to their neighbors letting them know they’re in trouble. The discovery, which shows that a process dubbed the DDR (DNA Damage Response) also controls communication from cell to cell, has implications for both cancer and aging.
The number of people with Alzheimer’s, both new cases and total numbers, continues to rise among the oldest segments of the population in contradiction of the conventional wisdom. Previous studies have suggested that the number of people with Alzheimer’s begins to level off and perhaps even drop in people age 90 and above, known as [...]
Engineers have achieved a major breakthrough with a new mini-mobile-modular (M3) smart water desalination and filtration system. The M3, which is portable and can be monitored and operated remotely via the web, showed in a recent field study in the San Joaquin Valley that it can desalt agricultural drainage water that was nearly saturated with [...]

Scientists have found that a receptor molecule involved in the first-line recognition of HIV-1 responds to the virus differently in women, leading to subsequent differences in chronic T cell activation, a known predictor of disease progression.

Researchers have developed an environmentally-friendly lubricating grease based on ricin oil and cellulose derivatives. The new formula does not include any of the contaminating components used to manufacture traditional industrial lubricants.
For patients undergoing repair of intact abdominal aortic aneurysms, long-term survival has improved in recent decades. For patients undergoing repair of ruptured abdominal aortic aneurysms, short-term survival has improved and long-term survival has remained stable. A less invasive procedure, endovascular aneurysm repair, is allowing surgical repair for older people with additional health problems.
