Why a promising breast cancer drug doesn’t work—and how to improve it

A treatment that appears effective in cancers such as myelofibrosis consistently fails in breast cancer clinical trials. A new study explains why.

This technique for studying cell receptors could have sweeping implications for drug development

Researchers created a tool capable of comprehensively mapping crucial interactions underlying drug efficacy in one superfamily of cell receptors.

New insight into the protein mutations that cause Rett syndrome

Findings bolster the idea that the functions of this protein—MeCP2—are more centered on nucleosomes, rather than other forms of DNA.

Second genetic sensor for DNA methylation discovered

CDCA7, whose mutations alter DNA methylation pattern and cause immunodeficiency, is a novel sensor for a special class of methylated DNA.

Researchers capture never-before-seen view of gene transcription

New tech reveals findings that address long-standing theories about how bacteria begin the process of making RNA from DNA.

Elizabeth Campbell launches Laboratory of Molecular Pathogenesis

The infectious disease specialist will continue her groundbreaking work on the transcriptomes of the pathogens behind tuberculosis and Covid.

How one scientist's fascination with RNA changed medicine forever

Thomas Tuschl has devoted his career to making discoveries that bridge the gap between bench and business—and have resulted in entirely new classes of drugs.

New Mtb study offers a novel paradigm for understanding bacterial transcription

A novel sequencing technique reveals a genetic trick TB may be using to evade the immune system and resist antibiotics.

A new way of thinking about how organ architecture develops 

By focusing on the emergent features of cell collectives, instead of individual cells, scientists forge a new path for understanding how organs develop their architecture.   

How intricate patterns arise in developing tissues

In developing bird skin, immature cells move around and form intricate patterns. Scientists are zeroing in on the mechanical forces guiding the process.

One protein's surprising partnership with single-stranded DNA

Linker histone H1 appears capable of distinguishing between single-stranded and double-stranded DNA, suggesting that its role in maintaining our genomes extends far beyond that of keeping chromosomes compact.

A synthetic antibiotic may help turn the tide against drug-resistant bacteria

The compound attacks MRSA, C. diff, and several other deadly pathogens. Its discovery demonstrates the power of combining computational biology, genetic sequencing, and synthetic chemistry to study bacterial evolution.

Titia de Lange elected to the Royal Society

She receives the honor for elucidating mechanisms of telomere protection and genome maintenance.

How a narrow-spectrum antibiotic takes aim at C. diff

A new study reveals how the drug fidaxomicin selectively targets a dangerous pathogen without causing harm to beneficial bacteria. The findings could inform the development of new narrow-spectrum antibiotics for treating other types of infection.

Insights into a cystic fibrosis treatment may herald a novel class of drugs 

Protein folding diseases, from Alzheimer's to Gaucher's, may one day be treated by a unique class of protein corrector molecules that are already helping manage cystic fibrosis.  

A novel compound might defeat multidrug-resistant bacteria common in hospitals

Increasingly, hospitalized patients contract infections that evade current antibiotics including colistin, long used as a last treatment option. The discovery of a new colistin variant might make it possible to outmaneuver these pathogens.

Linker histones tune the length and shape of chromosomes

A new study finds that proteins known as linker histones control the complex coiling process that determines whether DNA will wind into long and thin chromosomes, made up of many small loops, or short and thick chromosomes with fewer large loops.

Study reveals how ribosomes are assembled in human cells

Three-dimensional images of human small ribosomal subunits offer the most detailed explanation for how the cell's protein-making machines are assembled.

The physics behind a water bear's lumbering gait

Animals as small and soft as tardigrades seldom have legs and almost never bother walking. But a new study finds that water bears propel themselves through sediment and soil on eight stubby legs, in a manner resembling that of insects 500,000 times their size.

Inside the protein channel that keeps bacteria alive

A novel method for studying how one crucial membrane protein functions may pave the way for a new kind of broad-spectrum antibiotic.

An old antibiotic may combat drug-resistant tuberculosis

Drug-resistant strains of tuberculosis bacteria affect half a million people a year. A compound first discovered in the 1980s may be able to help.

As COVID-19 vaccines emerge, the search for antiviral drugs continues

Scientists are digging through drug libraries of 430,000 compounds, in pursuit of an antiviral drug that can stop the novel coronavirus in its tracks.

How cells use mechanical tension sensors to interact with their environment

In a painstaking experiment, scientists suspended a single protein filament between two microscopic beads. Their results have shed light on an elusive process in which cells receive and respond to mechanical cues.

Rockefeller's Charles M. Rice honored with Nobel Prize for research that contributed to a cure for hepatitis C

Rice will receive the 2020 Nobel Prize in Physiology or Medicine for research that led to a cure for hepatitis C, a viral disease affecting 170 million people worldwide. His lab worked on the virus for three decades and became the first to produce a version of it that could be grown and studied i...

Cancer cells use nerve-cell tricks to spread from one organ to the next

New research suggests that breast and lung tumors metastasize by hijacking a neural signaling pathway, potentially opening the door to better diagnostics and treatments.

How dividing cells avoid setting off false virus alarms

A new molecular structure explains how cells hold an alarm-triggering protein captive during cell division, preventing cells from targeting their own DNA.

A never-before-seen image of the coronavirus copy machine

The high-resolution 3D image can speed COVID-19 drug discovery.

Amid the rush for COVID-19 drugs, a case for the helicase

The enzyme is essential for the virus to replicate itself inside our cells. Scientists already have ideas for how to block it.

Transparent fish reveal the subtle, cellular dance in which sensory organs take shape

How do primitive cells “know” where to go during development? Scientists studying the fish equivalent of inner-ear hair cells have shown that biochemical and mechanical cues work together to orchestrate a highly complex arrangement.
