Metastases in cancer are often caused by a few abnormal cells. These behave more aggressively than the other cancer cells in a tumor. Researchers are now on a method to detect these cells.

Researchers have discovered the essential role of a new factor, LCOR, in enabling cancer cells to present tumor antigens on their surfaces. These antigens allow the immune system to recognize the tumor, an essential step if immunotherapy treatment is t…

Researchers have genetically engineered a microbial encapsulation system for therapeutic bacteria that can hide them from immune systems, enabling them to reach tumors more effectively and kill cancer cells in mice.

A new study unlocks the science behind a key ingredient — namely oxygen — in some of the world’s most violent volcanoes. The research offers a new model for understanding the oxidation state of arc magmas, the lavas that form some volcanoes, such as …

Researchers have found that people with severe alcohol use disorder miss more than double the number of workdays missed by individuals without alcohol use disorder.

A delta breakthrough infection generates a potent and broad neutralizing antibody response to SARS-CoV-2 in double vaccinated individuals, according to new research.

A promising new treatment for Creutzfeldt-Jakob disease (CJD) has shown ‘very encouraging’ early results following its use in six patients.

A large study examining the surgical management of traumatic brain injuries highlights regional inequalities in both major causes and treatment of such injuries.

An anticounterfeiting and tampering prevention system using ultraviolet and visible light has been recently proposed. This technology was developed using the metasurface, capable of freely controlling light and anticipated to be applicable in various i…

Parkinson’s disease is a neurodegenerative disorder characterized by the destruction of a specific population of neurons: the dopaminergic neurons. The degeneration of these neurons prevents the transmission of signals controlling specific muscle movem…

Researchers show which molecular processes promote secondary diseases in obesity.

An international research team has studied the flight behavior of the mysterious black swift. They found, among other things, that the black swift rises to extreme heights during a full moon, seemingly catching insects in the moonlight. And, during a l…

An international team of scientists found that sociality is linked to stress in Asian elephants. For example, loneliness increased male elephants’ level of stress, whereas having babies present reduced the stress level in female elephants.

A team of scientists found that a rare species of monkey in Bolivia has adapted to living in a fragmented forest by dieting and moving less during lean times.

Daytime napping among older people is a normal part of aging — but it may also foreshadow Alzheimer’s disease and other dementias. And once dementia or its usual precursor, mild cognitive impairment, are diagnosed, the frequency and/or duration of nap…

As SARS-C0V-2 variants emerged, researchers developed a PCR test that uses molecular beacons not only to diagnose COVID-19 infection, but also to identify the specific variant causing that infection.

A new study focuses on RNA molecules in plasma as biomarkers for Alzheimer’s disease in African Americans — the population at greatest risk for developing Alzheimer’s disease. This approach enabled researchers to pinpoint specific molecules in plasma …

In individuals with a genetic predisposition to Alzheimer’s disease, the immune cells of the brain — the ‘microglia’ — start exerting a protective effect up to two decades before the first symptoms appear. A team draws this conclusion based on a stud…

Researchers propose using the variations in distance between the Earth and the Moon, which can be measured with a precision of less than a centimeter, as a new gravitational wave detector within a frequency range that current devices cannot detect. The…

A brief traffic jam, a stuck door, or many passengers getting on and off at a stop – even small delays in the timetables of trains and buses can lead to major problems. A new artificial intelligence (AI) could help designing schedules that are less sus…
