Pathogen-fighting immune cells called tissue-resident memory CD8 T cells (TRM cells) go through a surprising transformation -- and relocation -- as they fight infections in the small intestine.

Maternal stress hormone levels during early pregnancy can have a lasting effect on the stress system of the offspring. The results of a long-term study on wild Assamese macaques in Thailand indicate that maternal stress in the first half of pregnancy is particularly relevant. Elevated stress hormones later during pregnancy or after birth did not have the same effects. The long-term study provides important insights into the influence of early life stages on the development of the stress system under natural environmental conditions.

Around 45 million years ago, a 4.6 feet-tall (1.40 meters) flightless bird called Diatryma roamed the Geiseltal region in southern Saxony-Anhalt. An international team of researchers report on the bird's fully preserved skull. The fossil was unearthed in the 1950s in a former lignite mining area in the Geiseltal in Germany. It was initially misclassified and thus led a shadowy existence until its rediscovery. The only other place that a similar skull fossil has been found is the USA.

Doctors could soon reduce epilepsy misdiagnoses by up to 70% using a new tool that turns routine electroencephalogram, or EEG, tests that appear normal into highly accurate epilepsy predictors, a study has found.

Researchers demonstrated that individuals who had childhood epilepsy have an increased accumulation of brain amyloid later in life, potentially predisposing them to late-onset brain amyloid disorders, such as Alzheimer's disease.

Using computational models, the researchers studied how the brain's reward-learning system functions in those with depression, especially among individuals experiencing anhedonia, the inability to feel pleasure. By analyzing dopamine-linked responses, they identified unique brain activity patterns that could help predict who is likely to recover.

When it comes to getting people to want to go places, the future is ever more lovely than the past, according to a new study. The study found that forestalgia-focused destination ads -- those that emphasize an idealized future -- are more effective at enticing travelers to click the purchase button for a vacation than ads based on fond recollections.

New research revealing the fingerprints of Sudden Infant Death Syndrome within blood samples could open the door to simple tests to identify babies at risk.

Copper chelation shows promising results in certain lung cancers where cells have two related phenomena: a heightened transcription factor responding to oxidative stress and a diminished level of bioavailable copper. Copper imbalances have long been implicated in cancer cell growth and other disease states.

Thanks to a new technology called Moscot ('Multi-Omics Single-Cell Optimal Transport'), researchers can now observe millions of cells simultaneously as they develop into a new organ -- for example, a pancreas.

Scientists have completed construction of the final chromosome in the worlds' first synthetic yeast genome following more than a decade of work, opening new possibilities for creating resilient, engineered organisms.

Investigators found negative mental health conditions among women firefighters may reduce levels of key hormone associated with ovarian reserve.

Experts highlight the need for a clear framework when it comes to AI research, given the rapid adoption of artificial intelligence by children and adolescents using digital devices to access the internet and social media.

Wild baboons failed to demonstrate visual self-recognition in a test carried out by anthropologists.

The Great Salt Lake, the largest saltwater lake in the Western Hemisphere, reached historic low levels in 2022, raising economic, ecological and public health concerns for Utah. New research is believed to be the first peer-reviewed study that quantifies the contributing factors to the record low water volume levels, which the researchers say is important for anticipating and managing future lake changes.

Like humans, mice will compete over territory and mates, and show increased confidence in their fighting skills the more they win. At first, a brain chemical called dopamine is essential for young males to master this behavior. But as they gain experience, the chemical grows less important in promoting aggression, a new study shows.

DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially, chemical energy is converted into mechanical motion by biasing the Brownian motion. The DNA-nanoparticle motor uses the 'burnt-bridge' Brownian ratchet mechanism. In this type of movement, the motor is being propelled by the degradation (or 'burning') of the bonds (or 'bridges') it crosses along the substrate, essentially biasing its motion forward.

Juvenile dolphins were found to have specialized receptors for fatty acids on their tongues, offering new insights into their growth and feeding habits.

A breakthrough study sheds new light on how brain cells relay critical information from their extremities to their nucleus, leading to the activation of genes essential for learning and memory.

A new study has identified a group of neurons that, when activated, can induce a hypometabolic state, akin to hibernation. The discovery could have far-reaching implications for conditions like obesity, cardiometabolic diseases, and even for space travel. The research team found that these neurons regulate key aspects of the brain-heart-gut axis.
