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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
A new computer algorithm can provide important information on a motor vehicle crash to help ambulance personnel and hospital staff better direct crash victims to the most appropriate care.
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.
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.
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.
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.
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.
All-cause mortality is higher for those who eat meat, particularly red or processed meat, on a daily basis, a review of large-scale studies involving more than 1.5 million people has found.
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.
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.
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.
