A cancer's surprise origins caught in action

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.

Been here before: How the brain builds place memories

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.

Scientists guide gold nanoparticles to form 'diamond' superlattices

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

Bee virus spread is manmade, driven by European honeybee populations

The spread of a disease that is decimating global bee populations is manmade, and driven by European honeybee populations, new research has concluded.

Alzheimer's insights in single cells

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

Fast, accurate cystic fibrosis test developed

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.

Bone loss associated with leukemia therapy occurs sooner than previously thought

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.

Walking on water: Researchers unravel science of skipping spheres

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.

Battery technology could charge up water desalination

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.

Can slow creep along thrust faults help forecast megaquakes?

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...

Psychological toll of Madoff fraud case went far beyond the victims, study finds

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.

Hepatitis virus-like particles as potential cancer treatment

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...

Nutrient deprivation kills kidney cancer cells

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

Scientists bridge different materials by design

It is possible to design and construct interfaces between materials with different structures by making a bridge between them, scientists have demonstrated.

European soil threats: What, where and why?

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.

Mitochondria shown to trigger cell aging

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 steroids before late preterm delivery reduces neonatal respiratory problems

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

Invasive measurement of blood glucose no longer necessary

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

Bachelor's paradise: Researcher finds female turtles outnumbering males

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.

Do venture capitalists matter?

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.
