Scientists snap together molecular building blocks of brain computing

Synapses are specialized brain structures where learning and memory occur. The efficient transmission of synaptic signals relies on the delicate structure and complex molecular composition of the synapses. However, the small size (several hundred nanometers in diameter) and heterogeneous nature of the synapses pose significant challenges in direct observation of the molecules inside synapses. Based

Scientists uncover proteins essential for memory B cell survival

Signals from two key proteins are essential for the survival of our ‘immunological memory’, according to new research from scientists at the Francis Crick Institute, published in the Journal of Experimental Medicine. Memory B cells are long-lived cells that confer immunological memory by providing rapid and robust antibody responses to infections our body has seen

Scientists grow the first functioning mini human heart model

Michigan State University researchers have created for the first time a miniature human heart model in the laboratory, complete with all primary heart cell types and a functioning structure of chambers and vascular tissue. In the United States, heart disease is the No. 1 cause of death. “These minihearts constitute incredibly powerful models in which

Scientists ID gene responsible for deadly glioblastoma

Scientists have identified an oncogene (a cancer-causing gene) responsible for glioblastoma, the deadliest brain tumor. The discovery offers a promising new treatment target for a cancer that is always fatal. The researchers say the oncogene is essential to the survival of the cancer cells. Without it, the cancer cells die. Scientists have already developed many

Scientists are already working on a coronavirus vaccine

Scientists are already working on a coronavirus vaccine – but warn it will likely be years before there is a shot to prevent the contagious illness which has so far killed 17 people A new coronavirus has sickened more than 500 people worldwide and killed 17 in China, where it originated  The first US case

Scientists find 'missing link' in allergic reactions to cosmetics

Scientists find ‘missing link’ in allergic reactions to popular skin creams: Fragrances, alcohols and immune protein combine to cause itchy rashes Contact dermatitis allergic reactions have been on the rise as the skin care and cosmetic industry has grown  But scientists have been unsure how skin creams and other products trigger the itchy red rash 

Scientists develop a new method to detect light in the brain

Researchers from Istituto Italiano di Tecnologia (IIT) and University of Salento, both in Lecce, Italy, and Harvard Medical School in Boston have developed a new light-based method to capture and pinpoint the epicenter of neural activity in the brain. The approach, described in Nature Methods, lays the foundation for novel ways to map connections across

Scientists discover first new HIV strain since 2000

Scientist Mary Rodgers spends her days tracking killers—elusive, constantly mutating viruses that travel the globe and are responsible for illness or death in millions of people. Wednesday, in an article published in the Journal of Acquired Immune Deficiency Syndromes, Rodgers and her team at Abbott, along with co-authors at the University of Missouri, announced their

Scientists discover signs a virus may trigger polio-like illness

Is THIS what causes mysterious polio-like illness in kids? Scientists discover signs that a common cold virus may trigger life-threatening paralysis in children Since 2014, nearly 600 people – mostly young children – have been diagnosed with acute flaccid myelitis   The mysterious polio-like condition has left young children with mysterious paralysis that becomes life-threatening for some

‘Cannabis addiction’ gene has been discovered by scientists

‘Cannabis addiction gene’ that could make people more likely to abuse the drug is discovered by scientists in a ‘really important’ breakthrough Gene CHRNA2 regulates a ‘nicotine receptor’ in the brain, scientists have said  Low levels of this receptor has been linked to an increased of marijuana abuse Discovery could help medics treat and even
