Researchers have developed DeepTCR, a software package that employs deep-learning algorithms to analyze T-cell receptor (TCR) sequencing data. T-cell receptors are found on the surface of immune T cells. These receptors bind to certain antigens, or proteins, found on abnormal cells, such as cancer cells and cells infected with a virus or bacteria, to guide the T cells to attack and destroy the affected cells.

As the world awaits the upcoming Olympic games, a new method for detecting doping compounds in urine samples could level the playing field for those trying to keep athletics clean. Recently, scientists reported an approach using ion mobility-mass spectrometry to help regulatory agencies detect existing dopants and future “designer” compounds.

Researchers have generated a precise map of brain connectivity from the largest output nucleus of the basal ganglia, an area known as the substantia nigra pars reticulata, or SNr. The findings offer a blueprint of the area’s architecture that revealed new details and a surprising level of influence connected to the basal ganglia.

A team has identified 76 overlapping genetic locations that shape both our face and our brain. What the researchers didn’t find is evidence that this genetic overlap also predicts someone’s behavioural-cognitive traits or risk of conditions such as Alzheimer’s disease. The findings could help debunk several persistent pseudoscientific claims about what our face reveals about us.

A new study suggests that masks and a good ventilation system are more important than social distancing for reducing the airborne spread of COVID-19 in classrooms. The study finds that aerosol transmission routes do not display a need for six feet social distancing when masks are mandated. These results highlight that with masks, transmission probability does not decrease with increased physical distancing, which emphasizes how mask mandates may be key to increasing capacity in schools and other places.

Researchers have developed a novel type of implantable sensor which can be operated in the body for several months. The sensor is based on color-stable gold nanoparticles that are modified with receptors for specific molecules. Embedded into an artificial polymeric tissue, the nanogold is implanted under the skin where it reports changes in drug concentrations by changing its color.

Cells from individuals with Major Depressive Disorder (MDD) were found to have higher than expected rates of methylation at specific sites on their DNA, when compared to cells from healthy individuals without MDD, according to a study. Methylation is a process by which DNA is chemically modified at specific sites, resulting in changes in the expression of certain genes.

A recent study finds that unhealthy eating behaviors at night can make people less helpful and more withdrawn the next day at work. The researchers found that, when people engaged in unhealthy eating behaviors, they were more likely to report having physical problems the next morning. Problems included headaches, stomachaches and diarrhea. In addition, when people reported unhealthy eating behaviors, they were also more likely to report emotional strains the next morning – such as feeling guilty or ashamed about their diet choices.

Researchers have developed innovative tough gel sheathed (TGS) sutures inspired by the human tendon. These next-generation sutures contain a slippery, yet tough gel envelop, imitating the structure of soft connective tissues. In putting the TGS sutures to the test, the researchers found that the nearly frictionless gel surface mitigated the damage typically caused by traditional sutures.

The millions of people who have chronic sinusitis deal not only with stuffy noses and headaches, they also commonly struggle to focus, and experience depression and other symptoms that implicate the brain’s involvement in their illness. New research links sinus inflammation with alterations in brain activity, specifically with the neural networks that modulate cognition, introspection and response to external stimuli.

New research has uncovered a surprising role for so-called “jumping” genes that are a source of genetic mutations responsible for a number of human diseases. In the new study, scientists made the unexpected discovery that these DNA sequences, also known as transposons, can protect against certain blood cancers.

A research team has uncovered a new technique that can speed up recovery from bone replacements. Novel micropillars, 10 times smaller than the width of a human hair, can change the size, shape and nucleus of individual stem cells and ‘trick’ them to become bone. Further research will look to improve the process of locking bone replacements with reduced risk of infection.
