Scientists reveal how inflammation affects the life of brain cells

New King’s College London research reveals how blood inflammation affects the birth and death of brain cells, which could offer new treatment targets for antidepressants. Mounting evidence points to high levels of inflammation as an important biological abnormality leading to depression in at least one third of patients. However, this […]

Diamonds track cancer

You would not expect diamonds to have anything to do with cancer treatment. But they can actually they improve patients’ chances of survival. “Using traditional techniques, it’s almost impossible to determine whether a cancer treatment has been 100 per cent or 99.9 per cent effective. The difference can have major […]

Worm study reveals role of stem cells in cancer

Researchers from the Aboobaker lab in the Department of Zoology used the worms (planarians) which are known for their ability to regenerate their tissues and organs repeatedly. This process is enabled by their stem cells, which constantly divide to make new cells. Cell migration – or the movement of cells […]

Large, crystalline lipid scaffolds bring new possibilities to protein, drug research

Proteins and drugs are often attached to lipids to promote crystallization or ensure delivery to targeted tissues within the body, but only the smallest proteins and molecules fit within these fat structures. A new study reveals a lipid structure that can support much larger proteins and molecules than before, potentially […]

New method to measure cell stiffness could lead to improved cancer treatments

UCLA biophysicists have developed a new method to rapidly determine a single cell’s stiffness and size — which could ultimately lead to improved treatments for cancer and other diseases. The method allows researchers to make standardized measurements of single cells, determine each cell’s stiffness and assign it a number, generally […]

Study Will Explore Link Between HIV, Micro-Strokes, and Dementia

New research will seek to understand why people who are HIV positive are more susceptible to a progressive cerebrovascular disease that can ultimately give rise to dementia.  One of the goals of the research is to identify new ways to prevent the blockages that occur in blood vessels and cause […]

Confronted With Bacteria, Infected Cells Die So Others Can Live, Penn Study Finds

The immune system is contantly performing surveillance to detect foreign organisms that might do harm. But pathogens, for their part, have evolved a number of strategies to evade this detection, such as secreting proteins that hinder a host’s ability to mount an immune response. In a new study, a team […]

Dying cancer cells: Back From the Brink

A new collaboration between two UC Santa Barbara labs explores the underlying molecular mechanism of a remarkable process called anastasis, a Greek word meaning “rising to life.” Building on earlier work showing that cells can recover from the brink of death, the new study demonstrates that anastasis is an active […]

Research shines light on circadian clock in our muscles

Biological clocks are ticking everywhere throughout our body. They trigger the release of the hormone melatonin during sleep, leading to the secretion of digestive enzymes at lunchtime or keep us awake at the busiest moments of the day. A “master clock” in the brain synchronises all the subsidiary ones in […]

New drug to supercharge immune cells in the fight against cancer

A new cancer treatment with the ability to normalise tumour blood vessels and boost the body’s immune system has been developed by researchers from The University of Western Australia and the Harry Perkins Institute of Medical Research. Many tumours can become resistant to the body’s immune system by creating a […]

DNA Mutations Shed in Blood Predicts Response to Immunotherapy in Patients with Cancer

In a first-of-its-kind study, University of California San Diego School of Medicine researchers report that a blood sample, or liquid biopsy, can reveal which patients will respond to checkpoint inhibitor-based immunotherapies. “We can help predict response to immunotherapy by measuring the number of mutations in circulating tumor DNA using a […]

Battling belly fat: Specialized immune cells impair metabolism in aging

In a new study, Yale researchers have described how nervous systems and immune systems talk to each other to control metabolism and inflammation. Their finding furthers scientists’ understanding of why older adults fail to burn stored belly fat, which raises the risk of chronic disease. The study also points to […]

How to Grow a Spine

Like a string of pearls, the spine is made of a series of similar vertebrae. A so-called segmentation clock creates this repetitive arrangement in developing embryos: Each time the clock ticks, a vertebra starts to form. In a paper published Sept. 21 in Cell, Harvard Medical School genetics professor Olivier Pourquié—whose lab […]

Editing Genes One by One Throughout Colorectal Cancer Cell Genome Uncovers New Drug Targets

Cancers driven by mutations in the KRAS gene are among the most deadly. For decades, researchers have tried unsuccessfully to directly target mutant KRAS proteins as a means to treat tumors. Instead of targeting mutant KRAS itself, researchers at University of California San Diego School of Medicine are now looking […]

Melanoma Cells Rewire to Resist Drug Treatment, Penn-Wistar Team Finds

In 2014, new combination therapies to treat patients with metastatic melanoma hit the market, helping extend the lives of those with this aggressive disease. Yet unfortunately, after several months of treatment, almost all patients on the regimen eventually relapsed. A study out this week in Nature, led by scientists from the University […]

Brain Found to Influence Embryo Development Much Earlier than Previously Thought

Tufts University researchers had recently discovered the brain to take an active part in bodily development well before movement or other independent behaviours occur. “Our research shows that the brain is engaged before that [autonomous activity], before it’s even fully built,” said corresponding author on the paper Michael Levin, PhD.

Parkinson's disease involves degeneration of the olfactory system

The first symptom of Parkinson's disease is often an impaired sense of smell. This neurodegenerative disease primarily causes irreparable damage to nerve cells in a brain area involved in movement control. How it affects the olfactory system has been unclear. Researchers at the Max Planck Research Unit for Neurogenetics in […]

UC San Diego Researchers Explain the Mechanism of Asexual Reproduction in Freshwater Flatworms

Freshwater planarians, found around the world and commonly known as “flatworms,” are famous for their regenerative prowess. Through a process called “fission,” planarians can reproduce asexually by simply tearing themselves into two pieces— a head and a tail—which then go on to form two new worms within about a week. […]

'Labyrinth' chip could help monitor aggressive cancer stem cells

Inspired by the Labyrinth of Greek mythology, a new chip etched with fluid channels sends blood samples through a hydrodynamic maze to separate out rare circulating cancer cells into a relatively clean stream for analysis. It is already in use in a breast cancer clinical trial. Tumor cells isolated from […]
