Looking at Evolution's Genealogy from Home

Evolution leaves its traces -- in particular -- in genomes. Researchers used '2-n-way' software to determine the relationships between species or individuals and compare any genome of and ...

A New Strategy of Cell Entry for Some Types of Parvoviruses

Researchers have uncovered a new parvovirus strategy for reaching the cell nucleus which is their site of replication. This new method of entry is a good example of host-driven ...

Faulty Transportation of Messenger RNA Is the Culprit in ALS

Researchers have discovered a function for the protein missing in many types of ALS and FTLD, two neurodegenerative diseases. In neurons, the protein TDP-43 bound to messenger RNA that codes for ...

Uncovering the Clock That Sets the Speed of Embryo Development

Why do pregnancies last longer in some species than others? Researchers have found the clock that sets the speed of embryonic development and discovered the mechanism is based on how proteins are ...

Humans Develop More Slowly Than Mice Because Our Chemistry Is Different

Scientists have found that the 'segmentation clock' -- a genetic network that governs the body pattern formation of embryos -- progresses more slowly in humans than in mice because the ...

Algorithms Uncover Cancers' Hidden Genetic Losses and Gains

Limitations in DNA sequencing technology make it difficult to detect some major mutations often linked to cancer, such as the loss or duplication of parts of chromosomes. Now, methods developed by ...

Time-Restricted Feeding Improves Health Without Altering the Body's Core Clock

For the first time, scientists have studied the early effects of time-restricted feeding on the daily periodic oscillations of metabolites and genes in muscle, and metabolites in blood. The findings ...

New Cause of Syndromic Microcephaly Identified

A team of international collaborators identifies a new cause of syndromic microcephaly caused by LMNB1 mutations that disrupt the nuclear ...

Metformin for Type 2 Diabetes Patients or Not? Researchers Now Have the Answer

Metformin is the first-line drug that can lower blood sugar levels in type 2 diabetes patients. One third of patients do not respond to metformin treatment and 5 per cent experience serious side ...

Scientists Uncover the Structural Mechanism of Coronavirus Receptor Binding

The spike protein on the surface of the SARS-CoV-2 coronavirus can adopt at least ten distinct structural states, when in contact with the human virus receptor ACE2, according to new ...

New Smart Drug Delivery System May Help Treatment for Neurological Disorders

A research team has created a smart drug delivery system that reduces inflammation in damaged nervous tissues and may help treat spinal cord injuries and other neurological disorders. The system, ...

New Gene Implicated in Neuron Diseases

Failures in a quality control system that protects protein-building fidelity in cells can lead to motor neuron degeneration and related diseases, according to a new study ...

New Path to Neuron Regeneration After Spinal Cord Injury

The astrocytic glial cell has the unique ability to form scar tissue around damaged neurons. The presence of scar tissue is associated with inhibitory effects on the regrowth of mature neurons that ...

Building Bridges: PARP Enzymes Bring Broken DNA Together

Researchers capture the structure of PARP enzymes at work, leading to a new understanding of DNA repair that may aid cancer treatments targeting the ...

Replicating a Genome Starts With a Twist, a Pinch, and a Bit of a Dance

DNA replication begins with a set of proteins -- the Origin of Replication Complex (ORC). Researchers published images of the human ORC in exquisite detail, showing how it changes shapes in dramatic ...

Scientists Uncover a Novel Approach to Treating Duchenne Muscular Dystrophy

Scientists have shown that pharmacological (drug) correction of the content of extracellular vesicles released within dystrophic muscles can restore their ability to regenerate muscle and prevent ...

Combining Two Precision Medicines Can Treat Drug-Resistant Cancers

Launching a dual-pronged attack on tumours using a combination of two innovative precision medicines could treat patients with multiple common cancers, a new clinical trial ...

Excessive Lung Release of Neutrophil DNA Traps May Explain Severe Complications in COVID-19 Patients

Researchers have detected significant amounts of DNA traps in distinct compartments of the lungs of patients who died from Covid-19. These traps, called NETs, are released massively into the airways, ...

DNA Damage Caused by Migrating Light Energy

Ultraviolet light endangers the integrity of human genetic information and may cause skin cancer. For the first time, researchers have demonstrated that DNA damage may also occur far away from the ...

Role of Protein in Development of New Hearing Hair Cells

Researchers have conducted a study that has determined the role that a critical protein plays in the development of hair cells. These hair cells are vital for hearing. Some of these cells amplify ...
