New research into Alzheimer's disease (AD) suggests that secondary infections and new inflammatory events amplify the brain's immune response and affect memory in mice and in humans -- even when these secondary events oc...

A new audio technique allows people to hear ultrasonic sounds at frequencies above 20,000 Hz and simultaneously perceive the direction the noise is coming from.

Researchers have shown that the antibody treatment reactivates the immune defense in patients with advanced-stage cancer. The treatment alters the function of the body's phagocytes and facilitates extensive activation of...

Scientists have demonstrated that conolidine, a natural painkiller derived from the pinwheel flower and traditionally used in Chinese medicine, interacts with the newly identified opioid receptor ACKR3/CXCR7 that regulat...

Researchers are developing a new filter membrane that is highly efficient at filtering and inactivating a wide variety of air-borne and water-borne viruses.

Researchers have discovered the detailed inner workings of the molecular motor that packages genetic material into double-stranded DNA viruses. The advance provides insight into a critical step in the reproduction cycle ...

After a detailed study of digital technology in a hospital, researchers find that experimenting with the technology, and then working to implement the best practices through coordinated governance, can help organizations...

Sickle cell disease leads to chronic pain, organ failure, and early death in patients worldwide. A team has demonstrated a gene editing approach that efficiently corrects the mutation underlying SCD in patient blood stem...

Hydrogels are polymer materials made mostly from water. They can be used in a wide range of medical and other applications. However, previous incarnations of the materials suffered from repeated mechanical stress and wou...

Conolidine, a natural pain killer derived from the pinwheel flower and frequently used in Chinese medicine, interacts with a newly identified opioid receptor that regulates natural opioid peptides produced in the brain.

Secondary infections and novel inflammatory events, even ones that occur external to the brain, amplify the brain's immune response and detrimentally impact cognition in mouse models of Alzheimer's disease.

Immune cells in the meninges come from bone marrow in the skull and migrate to the brain through special channels without passing through the blood. These immune cells help to guard the brain and spinal cord against infl...

SpaceX launched its 17th rocket of the year today (June 3), sending a robotic Dragon cargo capsule toward the International Space Station before nailing a landing at sea.

A new study brings into question conventional theories of the neuroscience of free will. Researchers found readiness potential reflects neural activity that underlies the formation of a decision to move, rather than the ...

The technology could be used in many fields, from drug development to materials research.

Sharks living in the open ocean experienced a previously unknown mass extinction event about 19 million years ago that wiped out nearly 90 per cent of the predators

Made from nearly 400 separate observations, this new image of the Milky Way's center reveals strange structures never seen before.

About 90% of sharks disappeared from the ancient oceans in less than 100,000 years, but it's unknown why.

Left- or right-handedness is a symmetry property that many macroscopic objects also exhibit and which is of immense importance, particularly for the bioactivity of organic molecules. Chirality is also relevant for physic...

The latest coronavirus news updated every day including coronavirus cases, the latest news, features and interviews from New Scientist and essential information about the covid-19 pandemic

A unique electron microscope, set to break new ground in biological imaging, is being installed today at the Rosalind Franklin Institute in the UK. The machine is able to image biological samples at up to a million frame...

So-called quantum dots are a new class of materials with many applications. Quantum dots are realized by tiny semiconductor crystals with dimensions in the nanometre range. The optical and electrical properties can be co...
