Mahmoud Ali, the study’s lead author and a postdoctoral researcher at the UI, says the findings provide a better understanding […]

Recovering after stroke is extremely difficult. Not only you have to try to live with the changes presented by the disease, you also have to understand the risk of developing a secondary stroke at any time. A team of scientists led by the Universities of Edinburgh and Nottingham have just […]

Certain lifestyle choices and conditions can increase your risk of having a stroke or a heart attack. Of course, routine check-ups is one of the more reliable ways to reduce this risk. In fact, now scientists from UCL and the University of Helsinki say that as many as 1 in […]

Researchers cause a lupus-like disease in mice by amplifying the amount of a single “master regulator” factor — suggesting both a root cause for known differences between the sexes and a target for new treatments. It’s one of the great mysteries of medicine, and one that affects the lives of […]

If you believe that great scientists are most creative when they’re young, you are missing part of the story. A new study of winners of the Nobel Prize in economics finds that there are two different life cycles of creativity, one that hits some people early in their career and another that […]

Chemotherapy is still our best bet when fighting leukaemia and other forms of cancer. However, even though it is the best available option now, it is definitely not without its own faults. Chemotherapy has a wide range of extreme side effects that make patients‘ lives miserable. Now scientists from the […]

Harnessing the body’s immune system to fight off cancer, a tactic known as immunotherapy, has tremendously improved outcomes for patients. But a lingering problem with immunotherapy, as with many other cancer treatments, is relapse. In many cases the tumor comes back, and doctors don’t know why. Now, research from the […]

Case Western Reserve University researchers and partners, including a collaborator at Cleveland Clinic, are pushing the boundaries of how “smart” diagnostic-imaging machines identify cancers—and uncovering clues outside the tumor to tell whether a patient will respond well to chemotherapy. The recent findings in breast and lung cancer research build off […]

DNA strands are long and fussy. They can actually tie into knots, makings parts of them difficult to read. And yet about 2 metres of DNA can be neatly packaged in each of our cells without much problem. How? Scientists from the Universities of Edinburgh and Padova in Italy studied […]

‘Protein whisperers’ create a new line of sight into the deadly disease PNNL scientists and colleagues have taken one of the most in-depth looks ever at the riot of protein activity that underlies colon cancer and have identified potential new molecular targets to try to stop the disease. The research […]

Ovarian cancer is usually diagnosed only after it has reached an advanced stage, with many tumors spread throughout the abdomen. Most patients undergo surgery to remove as many of these tumors as possible, but because some are so small and widespread, it is difficult to eradicate all of them. Researchers […]

The human body is held together by an intricate cable system of tendons and muscles, engineered by nature to be tough and highly stretchable. An injury to any of these tissues, particularly in a major joint like the shoulder or knee, can require surgical repairs and weeks of limited mobility […]
