By scanning the brains of people while they watched movie clips, neuroscientists have created the most detailed functional map of the brain to date. The fMRI analysis shows how different brain networks light up when participants viewed short clips from a range of independent and Hollywood films including Inception, The Social Network, and Home Alone.

The CRISPR tool is capable of repairing the genetic defect responsible for the immune disease chronic granulomatous disease. However, researchers have now shown that there is a risk of inadvertently introducing other defects. The CRISPR molecular scissors have the potential to revolutionize the treatment of genetic diseases. This is because they can be used to

A new study shows how students can better understand and interpret conditional probabilities. A new LMU study shows how students can better understand and interpret conditional probabilities. How trustworthy is a positive HIV test result? How probable is an actual infection when the test is positive? Even professionals often get such questions wrong, which can

Exhaled breath contains chemical clues to what's going on inside the body, including diseases like lung cancer. And devising ways to sense these compounds could help doctors provide early diagnoses -- and improve patients' prospects. Researchers report developing ultrasensitive, nanoscale sensors that in small-scale tests distinguished a key change in the chemistry of the breath

The cost of childbirth and postpartum health care results in significant, ongoing financial hardship, particularly for lower-income families with commercial insurance. About half of people who give birth in the United States are covered by commercial health insurance, which typically requires cost-sharing in the form of deductibles, copayments, and coinsurance. The cost of childbirth and

A team of bioengineers has developed a mathematical model that clarifies why interleukin-12 (IL-12) -- a potent immune-boosting protein that holds promise for cancer treatment -- loses effectiveness over time when used as an immunotherapeutic. The research challenges long-held assumptions about IL-12 s behavior in the body and offers a path toward safer and more

A new cell type provides a missing piece of the neural network regulating appetite. As you're deciding whether to eat one more potato chip, a pitched battle takes place in your brain. One group of neurons promotes hunger while another induces satiety. How quickly one group gains the upper hand determines how likely you are

Tiny circles called ecDNA are critical in cancer development and drug resistance. An international team publishes landmark studies detailing new findings and potential therapies. A trio of research papers from Stanford Medicine researchers and their international collaborators transforms scientists' understanding of how small DNA circles -- until recently dismissed as inconsequential -- are major drivers

Researchers have discovered a neural mechanism for memory integration that stretches across both time and personal experience. Mount Sinai researchers have discovered for the first time a neural mechanism for memory integration that stretches across both time and personal experience. These findings, reported in Nature, demonstrate how memories stored in neural ensembles in the brain

Thin, flexible device could help people with visual impairments 'feel' surroundings. Device comprises a hexagonal array of 19 actuators encapsulated in soft silicone. Device only uses energy when actuators change position, operating for longer periods of time on a single battery charge. A Northwestern University-led team of engineers has developed a new type of wearable

Researchers have developed a broad and deep genomic database of Latin Americans which gathers genome-wide data of Latin American populations into a single source and allows other scientists to easily add that population to their own research studies without straining budgets. It is commonly known that most genomic databases are biased toward people with European

Scientists have identified 16 genes that breast cancer cells use to survive in the bloodstream after they've escaped the low-oxygen regions of a tumor. Each is a potential therapeutic target to stop cancer recurrence, and one -- MUC1 -- is already in clinical trials. Scientists at the Johns Hopkins Kimmel Cancer Center have identified 16
