Researchers have, for the first time, visualized the origins of cancer from the first affected cell and watched its spread in a live animal. Their work could change the way scientists understand melanoma and other cancers and could lead to new, early treatments before the cancer has taken hold.
Neuroscientists have succeeded in activating dormant memory cells in rats. Using weak electrical impulses targeted at previously inactive cells in the hippocampus, the researchers induced the cells to recognize the exact place where the impulse had been first administered. The new study offers insight into the question of how memories are formed within our brains.
Using bundled strands of DNA to build Tinkertoy-like tetrahedral cages, scientists have devised a way to trap and arrange nanoparticles in a way that mimics the crystalline structure of diamond. The achievement of this complex yet elegant...Show More Summary
The spread of a disease that is decimating global bee populations is manmade, and driven by European honeybee populations, new research has concluded.
Study of plaque production holds promise of helping improve treatment for Alzheimer's, say investigators. Focusing on the form of the disease found in early onset Alzheimer's, in the 2 percent of patients who develop the progressiveShow More Summary
Researchers have developed a fast, inexpensive and highly accurate test to screen newborns for cystic fibrosis. The new method detects virtually all mutations in the CF gene, preventing missed diagnoses that delay babies’ ability to begin receiving essential treatment.
Significant bone loss -- a side effect of chemotherapy for acute lymphoblastic leukemia (ALL) - occurs during the first month of treatment, far earlier than previously assumed, report investigators.
Skipping stones across the water surface can be tricky. So why is it so easy to get such impressive water-skipping performance from an elastic ball? Researchers say they have answers that may reveal a lot about water impact physics.
The technology that charges batteries for electronic devices could provide fresh water from salty seas, says a new study. Electricity running through a salt water-filled battery draws the salt ions out of the water.
In Japan and areas like the Pacific Northwest where megathrust earthquakes are common, scientists may be able to better forecast large quakes based on periodic increases and decreases in the rate of slow, quiet slipping along the fa...
A new study explores where Bernie Madoff’s fraud case left its deepest impact and on whom -- not just among his direct victims, but also on how others viewed the trustworthiness of financial markets.
A new way to use the empty shell of a hepatitis E virus has been developed to carry vaccines or drugs into the body. The technique has been tested in rodents as a way to target breast cancer, and is available for commercial licensin...
The greedy metabolism of cancer cells to target kidney cell carcinomas, which kill more than 100,000 Americans each year, has been exploited by researchers. The team showed that the majority of renal cell cancers rewire their metabolism in a way that leaves them addicted to the nutrient cystine. Show More Summary
It is possible to design and construct interfaces between materials with different structures by making a bridge between them, scientists have demonstrated.
Over sixty soil experts have gone together and provided an up to date overview of European soil threats. The extensive report, which among other things provides information on the geographical spread of eleven soil threats, also addresses what kind of effect these threats may have on soil functions and ecosystem services, and why they occur.
Scientists have carried out an experiment which conclusively proves for the first time that mitochondria are major triggers of cell aging. This brings scientists a step closer to developing therapies to counteract the aging of cells, by targeting mitochondria.
Using corticosteroids in mothers at risk for late preterm delivery reduced the incidence of severe respiratory complications in their babies, new research indicates. The new study enrolled more than 2,800 pregnant women deemed at high risk of delivery during the late preterm period (34-36 weeks of gestation). Show More Summary
Diabetes patients traditionally monitor their daily blood glucose levels by using a conventional meter which requires blood sampling from the finger tips. The discomfort of pain and risk of infection can sometimes be a source of great stress and concern. Show More Summary
Rising global temperatures may skew gender imbalance among the marine turtle population, according to new research. The sex of marine hatchlings is influenced by incubating temperatures, and warmer temperatures produce a higher number of female hatchlings.
Venture capitalists do help startup firms by closely monitoring their development, say researchers, adding that the availability of direct airplane flights between the two parties helps improve that oversight.
