一个意想不到的门口到耳朵打开新的可能bilities for Hearing Restoration

Researchers have developed a new method to deliver drugs into the inner ear. The discovery was possible by harnessing the natural flow of fluids in the brain and employing a little understood backdoor into the cochlea. When combined to deliver a ...

Researchers Develop Digital Test to Directly Measure HIV Viral Load

A milliliter of blood contains about 15 individual drops. For a person with human immunodeficiency virus (HIV), each drop of blood could contain anywhere from fewer than 20 copies of the virus to more than 500,000 copies. Called the viral load, this is what is measured to allow clinicians to ...

Extinct Warbler's Genome Sequenced from Museum Specimens

The Bachman's warbler, a songbird that was last seen in North America nearly 40 years ago, was a distinct species and not a hybrid of its two living sister species, according a new study in which the full genomes of seven museum specimens of the bird were ...

Drug Decelerates Bacterial Race to Antibiotic Resistance

Researchers report that, in laboratory cultures and animal models, a drug significantly reduces the ability of bacteria to develop antibiotic resistance, which might prolong antibiotic ...

Scientists Discover New Embryonic Cell Type That Self-Destructs to Protect the Developing Embryo

Scientists have uncovered a new quality control system that removes damaged cells from early developing ...

The Speed of Life: A Zoo of Cells to Study Developmental Time

Researchers have used an unprecedented stem cell zoo to compare six different mammalian species and their developmental ...

Cryo Conservation: A Cool Solution to Saving Species from Extinction

In the face of the biodiversity crisis, and alarming data showing a 69% decline in global animal populations since 1970, researchers are banking on a cool solution to help save species from ...

A New Tool to Study Complex Genome Interactions

Genome Architecture Mapping captures complex, multi-way interactions in the genome. This is different than the workhorse technique of 3D genomics, which sees mostly two-way contacts, finds a new ...

Tethering of Shattered Chromosomal Fragments Paves Way for New Cancer Therapies

Scientists discover shattered chromosomal fragments are tethered together during cell division before being rearranged; destroying the tether may help prevent cancerous ...

Close Up on Aging Reveals How Different Cell Types in the Body Age at Different Pace

A team or researchers reports the first Aging Fly Cell Atlas (AFCA), a detailed characterization of the aging process in 163 distinct cell types in the laboratory fruit fly. Their in-depth analysis ...

Scientists Discover Small RNA That Regulates Bacterial Infection

Researchers have identified the major mechanism behind the transition between chronic and acute P. aeruginosa infections. Their research findings can inform the development of future treatments for ...

Scientists Investigate the Evolution of Animal Developmental Mechanisms, Show How Some of Earth's Earliest Animals Evolved

Lacking bones, brains, and even a complete gut, the body plans of simple animals like sea anemones appear to have little in common with humans and their vertebrate kin. Nevertheless, new research ...

CRISPR/Cas9-Based Gene Drive Could Suppress Agricultural Pests

Researchers have now used a gene-drive system to suppress an important agricultural ...

Taurine May Be a Key to Longer and Healthier Life

A study finds that deficiency of taurine, a molecule produced in our bodies, drives aging, and taurine supplements can improve health and increase lifespan in ...

当水温变化时,分子的运动rs of Cephalopods Do Too

Working with live squid hatchlings, scientists find the animals can tune their proteome on the fly in response to changes in ocean temperature via the unique process of RNA recoding. The findings ...


Octopuses Rewire Their Brains to Adapt to Seasonal Temperature Shifts

Octopuses don't thermoregulate, so their powerful brains are exposed to -- and potentially threatened by -- changes in temperature. Researchers report that two-spot octopuses adapt to seasonal ...

Remains of an Extinct World of Organisms Discovered

Newly discovered biomarker signatures point to a whole range of previously unknown organisms that dominated complex life on Earth about a billion years ago. They differed from complex eukaryotic life ...

Biological Clocks of People and Malaria Parasites Tick in Tune

Could the next weapon against malaria come from a better understanding of biological clocks? A new study shows that malaria parasites sync their gene activity with the circadian rhythms of their ...

Older Trees Accumulate More Mutations Than Their Younger Counterparts

A study of the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate suggests that older, long-lived trees play a greater role in generating ...

A Compound from Fruit Flies Could Lead to New Antibiotics

Research shows that the natural peptide, called drosocin, protects fruit flies from bacterial infections by binding to ribosomes in bacteria. Once bound, drosocin prevents the ribosome from making ...

Previously Unknown Antibiotic Resistance Widespread Among Bacteria
