Researchers have identify a set of biomarkers that could someday make it easy to spot the disease in a patient’s blood sample.

New research conducted by an international consortium shows that IBD and related conditions are now spreading through developing regions in Africa, Asia, and Latin America.

Researchers have released the full dataset from the Dallas Lifespan Brain Study, a decade-long project designed to track brain and cognitive health as people age and distinguish neurologically healthy paths from those indicating a likelihood of decline.

A new method could soon unlock the vast repository of biological information held in the proteins of ancient soft tissues. The findings could open up a new era for palaeobiological discovery.

How do we think, feel, remember, or move? It all depends on transmission of chemical signals in the brain, carried and released by molecular containers called vesicles. In a new study, researchers have modeled the vesicle cycle in unprecedented detail, revealing new information about the way our brains function. The paper describes an advanced computational model, which considers the complex interplay of vesicles, their cellular environments, activities and interactions, to predict vesicle behavior under different conditions.

Researchers compared the whole genome sequence of two genetically distinct lineages of bed bug, and their findings indicate bed bugs may well be the first true urban pest.

A new study reveals the biological secret to the Zika virus’s infectious success: Zika uses host cells’ own ‘self-care’ system of clearing away useless molecules to suppress the host proteins that the virus has employed to get into those cells in the first place.

In biology, enzymes have evolved over millions of years to drive chemical reactions. Scientists have now derived universal rules to enable the de novo design of optimal enzymes. As an example, they considered the enzymatic reaction of breaking a dimer into two monomer molecules. Considering the geometry of such an enzyme-substrate-complex, they identified three golden rules that should be considered to build a functional enzyme.

Scientists create a floss pick that samples cortisol within saliva as a marker of stress and quantifies it with a built-in electrode. The system uses a polymer casting technology that can be adapted to capture a wide a range of markers, such as estrogen for tracking fertility, or glucose for tracking diabetes. Ease of use allows monitoring to be incorporated into many areas of treatment.

Researchers have developed a vascularized organoid model of hormone secreting cells in the pancreas. The advance promises to improve diabetes research and cell-based therapies.
