Scientists can make high resolution images of the human spinal cord during surgery. The advancement could help bring real relief to millions suffering chronic back pain.

A recent study showed that it is possible to discern the composition of a buried pipe by striking an accessible portion of it and monitoring the sound waves that reach the surface. This method could help water utility companies verify the location of lead water lines without having to break ground.

People who have headaches after experiencing concussions may also be more likely to have higher levels of iron in areas of the brain, which is a sign of injury to brain cells, according to a preliminary study released today, March 5, 2024, that will be presented at the American Academy of Neurology's 76th Annual Meeting taking place April 13--18, 2024, in person in Denver and online.

Four children have remained free of detectable HIV for more than one year after their antiretroviral therapy (ART) was paused to see if they could achieve HIV remission, according to new research. The children, who acquired HIV before birth, were enrolled in a clinical trial in which an ART regimen was started within 48 hours of birth and then closely monitored for drug safety and HIV viral suppression. The outcomes reported today follow planned ART interruptions once the children met predefined virological and immunological criteria.

A research team has recently made a significant breakthrough in understanding how the DNA copying machine helps pass on epigenetic information to maintain gene traits at each cell division. Understanding how this coupled mechanism could lead to new treatments for cancer and other epigenetic diseases by targeting specific changes in gene activity.

In order to keep the population of harbour porpoises in Danish coastal waters stable, only 24 can perish in fishing nets each year. However, over 900 die each year.

The James Webb Space Telescope makes one of the most unexpected findings within its first year of service: A high number of faint little red dots in the distant Universe could change the way we understand the genesis of supermassive black holes.

Researchers have used machine learning to create a model that simulates reactive processes in organic materials and conditions.

Scientists have found our visual perception dips as our feet hit the ground. Further understanding this could help develop early diagnostics for neuromuscular or psychiatric illness; understand changes in mobility as we age; or help with sports science and athletic training.

Accounting for airflow dynamics rather than just airflow volume helped researchers measure an 85% reduction in airborne pathogens inside a working classroom.

Combining two treatments could be a promising option for people, especially military veterans, whose lives are negatively affected by post-traumatic stress disorder, finds a new study. In a clinical trial conducted among U.S. military veterans, participants who received brain stimulation with a low electrical current during sessions of virtual reality exposure reported a significant reduction in PTSD symptom severity.

About one-third of autistic people are unable to communicate using speech, and most are never provided an effective alternative. However, a new study suggests that many of these individuals are literate, raising the possibility that they could learn to express themselves through writing.

Whereas humans have one receptor on their tongues that can detect all sorts of sweet things, from real sugar to artificial sweeteners like aspartame, insects have many receptors that each detect specific types of sugars. Researchers have now uncovered one way insect receptors are able to be so selective, an insight they say will help us understand how animals decipher the chemical world and how we might mimic that ability in the future.

In a potentially game-changing development, scientists have revealed a new understanding of sometimes fatal viral infections that affect the heart. Traditionally, the focus has been on heart inflammation known as myocarditis, which is often triggered by the body's immune response to a viral infection. However, a new study sheds new light on this notion, revealing that the virus itself creates potentially dangerous conditions in the heart before inflammation sets in.

Scientists have developed an optical display based on mechano-optical mechanisms.

Researchers decode the neuronal basis of decision-making processes and can thus predict actions.

A new study provides insights into the role of microbes and their interaction as drivers of interspecific differences in coral thermal bleaching.

A surge of a neural-specific protein in the brain is the earliest-yet biomarker for Alzheimer's disease, report researchers studying a mouse model of the disease. Furthermore, the increased protein activity leads to the seizures associated with the earliest stages of neurodegeneration, and inhibiting the protein in the mice slowed the onset and progression of seizure activity. The neural-specific protein, PSD-95, could pose a new target for Alzheimer's research, early diagnosis and treatment.

Getting climate models to mimic real-time observations when it comes to warming is critical -- small discrepancies can lead to misunderstandings about the rate of global warming as the climate changes. A new study that when modeling warming trends in the Pacific Ocean, there is still a missing piece to the modeling puzzle: the effect of wind on ocean currents in the equatorial Pacific.
