Trilobites: Meet the Overcompensators, Plants That Get Tougher and Meaner When Attacked

2 hours agoNews : NYTimes: News

Damaging some plants sets off a molecular chain of events that causes them to grow back bigger and produce more seeds and chemical defenses simultaneously.

Medical News Today: Is gene editing ethical?

Advances in molecular biology are bringing the possibility of editing the human genome ever closer. But do we think this is ethical?

New function in gene-regulatory protein discovered

(Umea University) Researchers at Umeå and Stockholm universities in Sweden and Johns Hopkins University School of Medicine in the US have published a new study in the journal Molecular Cell. In the article, they show how the protein CBP affects the expression of genes through its interaction with the basal machinery that reads the instructions in our DNA.

Key molecular link in major cell growth pathway

A team of scientists has uncovered a surprising molecular link that connects how cells regulate growth with how they sense and make available the nutrients required for growth. The researchers' findings also implicate a new protein, SLC38A9, as a potential drug target in pancreatic cancer.

New discovery challenges long-held evolutionary theory

Monash scientists involved in one of the world's longest evolution experiments have debunked an established theory with a study that provides a 'high-resolution' view of the molecular details of adaptation.

New gene editing approach for alpha-1 antitrypsin deficiency shows promise in UMMS study

(University of Massachusetts Medical School) A study published in the journal Molecular Therapy by Christian Mueller, PhD, shows that using nuclease-free gene editing to correct cells with the mutation that causes alpha-1 antitrypsin deficiency leads to repopulation of a diseased liver with healthy cells.

Study reveals key molecular link in major cell growth pathway

(Whitehead Institute for Biomedical Research) A team of scientists led by Whitehead Institute has uncovered a surprising molecular link that connects how cells regulate growth with how they sense and make available the nutrients required for growth. The researchers' findings also implicate a new protein, SLC38A9, as a potential drug target in pancreatic cancer.

Molecular evolution: No escape from the tangled bank

2 days agoAcademics : Nature AOP

Ecological interactions emerge spontaneously in an experimental study of bacterial populations cultured for 60,000 generations, and sustain rapid evolution by natural selection.

The dynamics of molecular evolution over 60,000 generations

2 days agoAcademics : Nature AOP

Using data from sixty thousand generations of the E. coli long-term evolution experiment, the authors shed new light on the processes that govern molecular evolution.

Molecular basis of USP7 inhibition by selective small-molecule inhibitors

2 days agoAcademics : Nature AOP

Small molecules are identified that inhibit the ubiquitin-specific protease USP7 with high affinity and specificity as explained by co-crystal structures, and are shown to reduce tumour growth in mice.

Ferroelectric self-assembled molecular materials

Professor Martijn Kemerink of Linköping University has worked with colleagues in Spain and the Netherlands to develop the first material with conductivity properties that can be switched on and off using ferroelectric polarisation.

Art advancing science at the nanoscale

Could studying molecular biology ever be as fun as watching a Star Wars movie? Two scientists decided to create their own science film to entertain viewers, and ended up making new scientific discoveries in the process. The researchers-turned-filmmakers...Show More Summary

Death by a thousand cuts? Not for small populations

(Michigan State University) In a paper published in Nature Communications, Christoph Adami, professor of microbiology and molecular genetics, and graduate student Thomas LaBar have provided a look at how certain species survive by evolving a greater ability to weed out harmful mutations -- a new concept called 'drift robustness'.

KLF4 Involved in Autophagy and Age-Related Vascular Dysfunction

2 days agoHealth / Aging : Fight Aging

There are any number of specific proteins associated with the progression of aging and its dysfunctions in one way or another. The overwhelming majority are not directly involved in the fundamental molecular damage that causes aging, but rather in the secondary consequences and reactions to that damage. Show More Summary

New 3-D imaging technique for future precision medicine toolbox

For an illness like cancer, doctors often turn to computed tomography (CT) scans for a more definitive diagnosis, based on reconstructing a 3-D organ from multiple 2-D image slices. At the molecular level, such 3-D scans could become an important part of precision medicine: a future of tailoring treatment decisions to each patient's unique cellular features.

Scientists have discovered a new link between sugar and tumor growth

There's more bad news for sugar lovers. After nine years of research, molecular biologists in Belgium have discovered that sugars stimulate tumor growth. Their results, published Friday in the journal Nature Communications, help explain...Show More Summary

An exceptionally preserved sea turtle reveals ancient sun protection

Researchers at Lund University in Sweden have discovered well-preserved pigments and other biomolecules in a 54 million-year-old baby sea turtle. The molecular analyses show that the turtle’s shell contained pigments to protect it from...Show More Summary
