Persistent DNA Damage in the Placenta Affects Pregnancy Outcomes

Scientists have shown that a dysfunctional placenta can play a previously unrecognized role during the earliest stages of development in mouse models of Cornelia de Lange syndrome. People with this ...

Scientists Uncover Immune Cells That May Lower Airway Allergy and Asthma Risk

Scientists offer a clue to why non-allergic people don't have a strong reaction to house dust mites. They've uncovered a previously unknown subset of T cells that may control allergic ...

Researchers Uncover Cancer Cell Vulnerabilities; May Lead to Better Cancer Therapies

A new study reveals a protein responsible for genetic changes resulting in a variety of cancers, may also be the key to more effective, targeted cancer ...

Repairing Thousands of Disease-Causing Mutations

Researchers have created a new searchable library of base editors -- an especially efficient and precise kind of genetic corrector. Using experimental data from editing more than 38,000 target sites ...

Unlocking PNA's Superpowers for Self-Assembling Nanostructures

Researchers have developed a method for self-assembling nanostructures with gamma-modified peptide nucleic acid, a synthetic mimic of DNA. The process has the potential to impact nanomanufacturing ...

Study Identifies Mechanism Affecting X Chromosome That Could Lead to New Disease Therapies

Learning how to inactivate and reactivate an X chromosome would have important implications for medicine. A notable category of beneficiaries could be people with certain congenital diseases known as ...

Brain Cells Can Harbor and Spread HIV Virus to the Body

Researchers have found that astrocytes, a type of brain cell can harbor HIV and then spread the virus to immune cells that traffic out of the brain and into other organs. HIV moved from the brain via ...

Denisovan DNA Influences Immune System of Modern Day Oceanian Populations

More than 120,000 novel human genetic variations that affect large regions of DNA have been discovered, some of which are linked to immune response, disease susceptibility or ...

Putting 'Super' in Natural Killer Cells

Using induced pluripotent stem cells (iPSCs) and deleting a key gene, researchers have created natural killer cells -- a type of immune cell -- with measurably stronger activity against a form of ...

Researchers Model Human Stem Cells to Identify Degeneration in Glaucoma

More than 3 million Americans have glaucoma, a serious eye condition causing vision loss. Using human stem cell models, researchers found they could analyze deficits within cells damaged by glaucoma, ...

Tropical Disease in Medieval Europe Revises the History of a Pathogen Related to Syphilis

Plague was commonplace in medieval times, so finding its victims in a 15th century Lithuanian graveyard was no surprise. However, discovering one woman with a second disease, yaws -- a close relative ...

From Bacteria to You: The Biological Reactions That Sustain Our Rhythms

Methylation and the circadian clock are both conserved mechanisms found in all organisms. Researchers found that inhibiting methylation with a specific compound disrupts the circadian clock in most ...

Lack of Mitochondria Causes Severe Disease in Children

Researchers have discovered that excessive degradation of the power plants of our cells plays an important role in the onset of mitochondrial disease in children. These inherited metabolic disorders ...

New Genetic Defect Linked to ALS

Researchers have identified how certain gene mutations cause amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. The pathway identified by the researchers may also be ...
