A newly discovered mechanism reveals how Parkinson’s disease can spread

Tiny channels between nerve cells are involved in a newly discovered mechanism of how Parkinson’s disease can spread throughout the brain. Researchers from LiU demonstrate that harmful protein aggregates can “hitch a lift” with channel-forming proteins, and in this way spread to healthy cells. Neurodegenerative diseases, such as Alzheimer’s, Parkinson’s […]

New method for analyzing genes activity helps predict cancer patients survival

An international research team developed a new method for determining cell types in a tissue sample. The scientists determined the link between the activity of genes in the same cell type and made a model capable of “recognizing” different cell types in mixed samples based on this relation. This approach […]

A new molecule to boost modern cancer therapies

Highly effective modern cancer therapies rely on immune cells to attack and shrink tumours. Medicine instructs body’s immune system to attack cancer cells, which is a safer approach, but scientists from the University of Edinburgh found a way to boost this effect. They found a molecule that boosts the function […]

A step closer to identifying cause of a blinding disease

Leber hereditary optic neuropathy (LHON) is an inherited form of vision loss that causes people to have trouble with their colour vision and difficulty seeing in the centre of their visual field. Due to the founder effect from the filles du roi, there is a disproportionate preponderance of a particular LHON mutation among […]

Synthetic E. coli pushes the limits of gene synthesis

Designing and building organisms from scratch could be the Holy Grail of synthetic biology. It therefore comes as no surprise that genome synthesis works get a lot of attention and are celebrated as high profile works form the community. In 2016 J. Craig Venter Institute scientists reported the synthesis of […]

How Learning and Decision-Making Share a Common Underlying Brain Mechanism

In a pair of recently published papers, researchers at Carnegie Mellon University, along with local and international collaborators, shed light on how specific circuits in the brain can simultaneously make decisions and learn from their outcomes. Consider eating brunch at your favorite restaurant: How do you know whether the eggs […]

Artificial Intelligence system spots lung cancer before radiologists

Deep learning — a form of artificial intelligence — was able to detect malignant lung nodules on low-dose chest computed tomography (LDCT) scans with a performance meeting or exceeding that of expert radiologists, reports a new study from Google and Northwestern Medicine. This deep-learning system provides an automated image evaluation […]

Hypertension Found in Children Exposed to Flower Pesticides

In a study published in the journal Environmental Research, researchers at University of California San Diego School of Medicine found higher blood pressure and pesticide exposures in children associated with a heightened pesticide spraying period around the Mother’s Day flower harvest. This study involved boys and girls living near flower […]

Scientists are developing nano-submarines for drug delivery

Treating diseases on cellular level is extremely difficult because of the microscopic scale. It is especially true for cancer, which is why contemporary therapies are affecting a lot of the surrounding tissue. However, chemical and biomedical engineers from the UNSW Sydney proved that it is possible to design effective miniscule […]

Proton Therapy Lowers Risk of Side-Effects Compared to Conventional Radiation

Cancer patients getting proton therapy instead of traditional photon radiation are at a significantly lower risk of experiencing side-effects from their radiation therapy, while cure rates are almost identical between the two groups. Researchers in the Perelman School of Medicine at the University of Pennsylvania conducted the largest review of its […]

Researcher wants to unlock the mysteries of strabismus

Strabismus, also known as being cross-eyed or having a wandering eye, is one of the most common reasons that children undergo eye surgery. But little has changed in its treatment since the 1800s, according to Jolene Rudell, acting assistant professor of ophthalmology at the University of Washington School of Medicine. […]

How a zebrafish could help solve the mysteries of genetic brain disease

A close look at the rapidly developing zebrafish embryo is helping neuroscientists better understand the potential underpinnings of brain disorders, including autism and schizophrenia. Researchers at The Ohio State University were interested in understanding changes in neurological development that arise from a genetic defect associated with neurological disease – specifically, […]

Mapping bone-marrow microenvironment sheds fresh light on leukaemia

Stem cells are surrounded and protected by the stem-cell niche – the microenvironment – of the tissue in which they are found. Researchers at Karolinska Institutet have mapped the stem-cell niche in the bone marrow of mice and studied how it is influenced by developing leukemia. Their results, which are […]

Study Explores Why Prostate Cancer Mortality is Higher in Black Men

Black men are more likely to be diagnosed with prostate cancer and nearly 2.5 times more likely to die of the disease compared to non-Hispanic white men. The question is why. Are black men more likely to carry genes that drive deadlier forms of the disease? What societal disparities might […]

Determining Risk of Diabetic Kidney Disease

Researchers ID circulating proteins involved in progression of diabetic kidney disease. In a breakthrough study published in Nature Medicine, Harvard Medical School researchers at Joslin Diabetes Center have identified a group of 17 circulating inflammatory proteins that are consistently associated with the development and progression of diabetic kidney disease. These 17 […]

Names prompt distinct brain activity in preschoolers

A study from Penn and CHOP found that when preschoolers with autism spectrum disorder hear their name, their neural patterns match those of their typically developing peers. The finding held regardless of whether the child’s mom or a stranger called the name. Infants as young as 6 months old can […]

Study probes the powering of contractions in heart failure

Current treatments can slow progression of heart failure, but do not address the underlying issues, including specific problems that cause systolic heart failure.  In this condition, the heart doesn’t contract vigorously enough in  pushing blood into the body’s circulation. The heart muscle contractions that  pump blood are generated by interactions […]
