In 1956, theoretical physicist David Pines predicted that electrons in a solid could form a composite particle called a demon. It's eluded detection since its prediction....until now.
Detecting extremely distant stars, or those closest in time to the big bang, can provide insights into the first few chapters of the history of our universe. In 2022, the Hubble Space Telescope broke its own record, and spotted the most distant star yet. This star, nicknamed Earendel, emitted its light within the universe’s first billion years.
Blood disorders known as myelodysplastic syndromes/neoplasms are commonly misdiagnosed – putting patients at increased risk for treatment mistakes and other potentially harmful consequences. A new study highlights the vital need for strong coordination between clinicians and skilled pathologists to ensure accurate, timely diagnosis of blood cancers.
After more than a decade of work, electrons are now flying through a new superconducting accelerator at the Department of Energy’s SLAC National Accelerator Laboratory, preparing to power the world’s most powerful X-ray free electron laser. This project – named the Linac Coherent Light Source II (LCLS-II) – is now steps away from releasing X-ray flashes that will open a new era in scientific research at that atomic level.
Yasemin Ozkan-Aydin, electrical engineering doctoral student Nnamdi Chikere and undergraduate John Simon McElroy, a Naughton Fellow from University College Dublin, have designed and built a robotic sea turtle, which they are testing in varied environments on Notre Dame’s campus. Their robot mimics a real sea turtle’s propulsion: its front flippers move it forward while its smaller hind flippers allow it to change direction.
Researchers at Dana-Farber Cancer Institute have created an AI-based tool that uses tumor gene sequencing data to predict the primary source of a patient’s cancer. The study, published in in Nature Medicine, suggests that this predictive tool, called OncoNPC, could help guide treatment of cancer and improve outcomes in difficult to diagnose cases.

A first-of-its-kind analysis of historical DNA ties tens of thousands of living people to enslaved and free African Americans who labored at an iron forge in Maryland known as Catoctin Furnace soon after the founding of the United States. The study, spurred by groups seeking to restore ancestry knowledge to African American communities, provides a new way to complement genealogical, historical, bioarchaeological, and biochemical efforts to reconstruct the life histories of people omitted from written records and identify their present-day relatives.
In a first, scientists define five types of colon neurons specialized for sending different signals to the brain.
The number of girls diagnosed with precocious puberty increased during the COVID-19 pandemic due to potential risk factors such as increased screen time and less physical activity, according to a new study published in the Journal of the Endocrine Society.
Teens who have been bullied by their peers, or who have considered or attempted suicide, may be more likely to have more frequent headaches than teens who have not experienced any of these problems, according to a study published in the August 2, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study does not prove that bullying or thoughts of suicide cause headaches; it only shows an association.
New research shows how using molecular tools and alternative gene splicing can make a protein called CEACAM1 more protective against liver injury during transplantation, thus reducing organ injury and ultimately improving post-transplant outcomes.
A sociological study by the University of Zurich confirms that a considerable proportion of employees perceive their work as socially useless. Employees in financial, sales and management occupations are more likely to conclude that their jobs are of little use to society.
Cancer research centers conducting clinical trials could enroll more patients from underrepresented racial and ethnic groups by placing greater emphasis on relieving investigators of the costs of translating consent documents into languages other than English, according to a UCLA Jonsson Comprehensive Cancer Center study.
The Fishhook. The Thin One. These are just two of the striking targets revealed in new detail by NASA’s James Webb Space Telescope. In July 2022 Webb observed El Gordo, a galaxy cluster that existed 6.2 billion years after the big bang. It was selected as the most massive galaxy cluster known at that time in cosmic history.
An international team of researchers has found a genetic variant that may explain why some people of African ancestry have naturally lower viral loads of HIV, reducing their risk of transmitting the virus and slowing progress of their own illness.
Birds can be electrocuted if they come into contact with two energized parts of a power line at once—which can happen when they spread their wings to take off from or land on a power pole.
Almost half of patients who experienced a stroke in the right cerebral hemisphere later develop a very unusual symptom: they lose the ability to perceive what is happening in the left side of space.
A new study lends further weight to the idea that vision problems and dementia are linked. In a sample of nearly 3,000 older adults who took vision tests and cognitive tests during home visits, the risk of dementia was much higher among those with eyesight problems – including those who weren’t able to see well even when they were wearing their usual eyeglasses or contact lenses.
New analysis from researchers at the George Washington University links lead exposure either in utero or during childhood with an increased risk of engaging in criminal behavior in adulthood. While prior research has found an association between lead exposure and criminal behavior at the aggregated population level, this is the first review to bring together the existing data at the individual-level of exposure and effects.
CAR-T immune therapies could be effective against solid tumors if the right targets are identified, a new study led by University of Illinois Urbana-Champaign researchers suggests. The researchers successfully deployed CAR-T in a mouse model of ovarian cancer, a type of aggressive, solid-tumor cancer that has eluded such therapies until now.

A young planet whirling around a petulant red dwarf star is changing in unpredictable ways orbit-by-orbit. It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere — causing it to puff off the planet. But during one orbit observed with Hubble, the planet looked like it wasn't losing any material at all, while an orbit observed with Hubble a year and a half later showed clear signs of atmospheric loss.
UC San Diego Health is among the first in the nation to perform an experimental regenerative brain cell therapy for epilepsy aimed at eliminating seizures.
People who carry the gene variant associated with the strongest risk for Alzheimer’s disease may lose their ability to detect odors earlier than people who do not carry the gene variant, which may be an early sign of future memory and thinking problems, according to a study published in the July 26, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The gene variant associated with this increased risk of Alzheimer’s is called APOE e4.
