Retention of One Normal Version of BRCA Gene in Breast and Ovarian Cancers Influences Patient Survival, According to Penn-Led Study

Researchers found a relationship between the genetics of tumors with germline BRCA1/2 mutations and whether the tumor retains the normal copy of the BRCA1/2 gene, and risk for primary resistance to a common chemotherapy that works by destroying cancer cells’ DNA.

“What’s in your water?” has become an increasingly fraught question for many people in the U.S. and around the world. Getting the answer isn’t always easy or cheap. Today, scientists are reporting that they are using the familiar “coffee-ring effect” to analyze multiple components in a single drop of water easily, quickly and cheaply. And someday, the public could use the method to test their own tap water.

Cyborg Bacteria Outperform Plants When Turning Sunlight Into Useful Compounds (Video)

Photosynthesis provides energy for the vast majority of life on Earth. But chlorophyll, the green pigment that plants use to harvest sunlight, is relatively inefficient. To enable humans to capture more of the sun’s energy than natural photosynthesis can, scientists have taught bacteria to cover themselves in tiny, highly efficient solar panels to produce useful compounds.

Getting Fat to ‘Talk’ Again Could Lower Blood Glucose and Weight

NM254Diabetes2.jpg

Diabetes is a tough disease to manage. Oral medications, insulin shots, close monitoring of blood sugar, dietary changes and exercise can all factor into a person’s treatment regimen. Now researchers are exploring a novel, simpler approach: implanting a polymer sponge into fat tissue. Their study has shown that in obese mice with symptoms resembling Type 2 diabetes, the implant reduced weight gain and blood-sugar levels — by getting the fat to “talk” again.

Turning Human Waste Into Plastic, Nutrients Could Aid Long-Distance Space Travel (Video)

Imagine you’re on your way to Mars, and you lose a crucial tool during a spacewalk. Not to worry, you’ll simply re-enter your spacecraft and use some microorganisms to convert your urine and exhaled carbon dioxide (CO2) into chemicals to make a new one. That’s one of the ultimate goals of scientists who are developing ways to make long space trips feasible.

Female patients with locally advanced esophageal cancer that is treated with chemotherapy and radiation therapy before surgery are more likely to have a favorable response to the treatment than male patients are, and women are less likely to experience cancer recurrence.

A nanolaser known as the spaser can serve as a super-bright, water-soluble, biocompatible probe capable of finding metastasized cancer cells in the blood stream and then killing these cells, according to a new research study.
