No longer lost in translation: Biochemists watch gene expression in real time

Thu, 05/05/2016 - 6:48pm
Biochemists have made a live-cell movie of RNA translation, the fundamental cellular process by which a ribosome decodes a protein. Sixty years after Francis Crick first described it, these scientists have illuminated, in a single living cell, this final step of gene expression. Their tools: some clever protein engineering, and a custom-built microscope that can show single-RNA translation with nanoscale precision.

Sea star juveniles abundant, but recovery is anything but guaranteed

Thu, 05/05/2016 - 6:48pm
An unprecedented number of juvenile sea stars have been observed off the Oregon coast over the past several months -- just two years after one of the most severe marine ecosystem epidemics in recorded history nearly wiped the population out.

Drug combination could help reduce risk of death in type 2 diabetes

Thu, 05/05/2016 - 6:47pm
People with type 2 diabetes treated with insulin plus metformin had a reduced risk of death and major cardiac events compared with people treated with insulin alone, a new study shows.

Six new fossil species form 'snapshot' of primates stressed by ancient climate change

Thu, 05/05/2016 - 6:47pm
Researchers have unearthed a "mother lode" of a half-dozen fossil primate species in southern China.These primates eked out an existence just after the Eocene-Oligocene transition, when drastic cooling slashed their populations, rendering discoveries of such fossils especially rare.

Tsunami risk: World's shallowest slow-motion earthquakes detected offshore of New Zealand

Thu, 05/05/2016 - 6:47pm
New research indicates that slow-motion earthquakes or 'slow-slip events' can rupture the shallow portion of a fault that also moves in large, tsunami-generating earthquakes. The finding has important implications for assessing tsunami hazards. The discovery was made by conducting the first-ever detailed investigation of centimeter-level seafloor movement at an offshore subduction zone.

Men also at risk for osteoporosis

Thu, 05/05/2016 - 6:22pm
Screening women for osteoporosis is now routine, however, when it comes to men, most are never screened and therefore suffer the consequences of the disease. In the U.S., nearly 1.5 million men over 65 have osteoporosis, and another 3.5 million men are at risk for developing the disease.

Smartphone app for monitoring heart palpitations is comparable to 14-day event monitor

Thu, 05/05/2016 - 6:09pm
A smartphone app that tracks palpitations in heart patients provides comparable performance to the 14-day event monitors that are the current standard of care, according to a new study.

Come to think of it or not: Study shows how memories can be intentionally forgotten

Thu, 05/05/2016 - 6:09pm
Context plays a big role in our memories, both good and bad. Bruce Springsteen's 'Born to Run' on the car radio, for example, may remind you of your first love -- or your first speeding ticket. But a new brain scanning study shows that people can intentionally forget past experiences by changing how they think about the context of those memories.

We are bad judges of friendship, new study shows

Thu, 05/05/2016 - 6:09pm
Only half of your friends would consider you their friend, a new study suggests. People have a very poor perception of friendship ties, and this limits their ability to influence their "friends," according to the research.

Gene replacement therapy offers viable treatment option for fatal disease

Thu, 05/05/2016 - 6:09pm
Spinal muscular atrophy (SMA) is a disease that causes progressive degeneration in the nerve cells that control muscles, thereby causing muscle weakness and eventually death. SMA affects approximately 200,000 people in the US, often children. Now, researchers are studying a subtype of SMA, spinal muscular atrophy with respiratory distress type 1 (SMARD1), and have developed a gene replacement therapy that can be used to treat and control the disease in the future.

Two-minute warnings make kids' 'screen time' tantrums worse

Thu, 05/05/2016 - 6:07pm
Giving young children a two-minute warning that 'screen time' is about to end makes transitions away from tablets, phones, televisions and other technological devices more painful, a new study has found.

Molybdenum disulfide holds promise for light absorption

Thu, 05/05/2016 - 6:07pm
Using a layer of molybdenum disulfide less than 1 nanometer thick, researchers have designed a system that can absorb more than 35 percent of incident light in the 400- to 700-nanometer wavelength range.

Measuring a black hole 660 million times as massive as our sun

Thu, 05/05/2016 - 6:03pm
It's about 660 million times as massive as our sun, and a cloud of gas circles it at about 1.1 million mph. This supermassive black hole sits at the center of a galaxy dubbed NGC 1332, which is 73 million light years from Earth. And an international team of scientists has measured its mass with unprecedented accuracy.

Portable device worn on eyeglasses offers hope for people with low vision

Thu, 05/05/2016 - 6:03pm
A miniature camera using optical character-recognition technology, mounted onto the eyeglasses of people who are considered legally blind, dramatically improves their ability to read an email, newspaper article, menu or page in a book, a study has found.

Staging system to explain complexity, manage expectations in revision rhinoplasty

Thu, 05/05/2016 - 6:03pm
Can a staging system -- much like one used to classify cancerous tumors -- help facial plastic surgery patients understand the complexity of their revision rhinoplasty and help to manage their expectations? A new article looks into the issue.

Research findings reveal potential to reverse cancer-related nerve pain

Thu, 05/05/2016 - 6:00pm
A study providing new information about neuropathic pain afflicting some 90 percent of cancer patients who have had nerve damage caused by tumors, surgery, chemotherapy or radiation indicates gene therapy as a possible treatment.

Study points to therapeutic target for common, aggressive ovarian cancer

Thu, 05/05/2016 - 6:00pm
Small, non-coding molecules called microRNAs are known to play an important role in cancer development. Researchers now have shown their significance is greater than previously thought, a finding that could lead to new therapeutic approaches for the most common and deadly form of ovarian cancer.

Signaling network linked to heart valve defects

Thu, 05/05/2016 - 6:00pm
A cell-to-cell signaling network in mice that serves as a developmental timer that could provide a framework for better understanding the mechanisms underlying human heart valve disease, say scientists.
