Enlarged perivascular spaces around small blood vessels in the brain may be a biomarker for cognitive decline, and ultimately dementia, a new study reports.

(Nagoya University) Ceramic matrix composites (CMCs) are incredibly strong materials used in jet engines, gas turbines, and cutting tools for nickel superalloys. Aluminum oxide (Al2O3) is hard and chemically inert, and t...

Study sheds light on the effects of allostatic closed-loop neurotechnology on functional brain connectivity in those with traumatic stress.

Laser-induced breakdown spectroscopy (LIBS) is a rapid chemical analysis tool. A powerful laser pulse is focused on a sample to create a microplasma. The elemental or molecular emission spectra from that microplasma can ...

The study of warm dense matter helps us understand what is going on inside giant planets, brown dwarfs, and neutron stars. However, this state of matter, which exhibits properties of both solids and plasmas, does not occ...

With a powerful enough light, you can see things that people once thought would be impossible. Large-scale light source facilities generate that powerful light, and scientists use it to create more durable materials, bui...

Colonies of naked mole rats share the same dialect, which may help them recognise friend from foe - and these are set by the colony's queen

Tiny molecular forces at the surface of water droplets can play a big role in laser output emissions. As the most fundamental matrix of life, water drives numerous essential biological activities, through interactions wi...

Seawater is abundant and cheap, making it a tempting resource to meet the world's growing need for clean drinking water and carbon-free energy. Now researchers have reported a new catalyst that can be made quickly and in...

Scientists discovered that AIM2 is important for the proper function of regulatory T cells, or Treg cells, and plays a key role in mitigating autoimmune disease. Treg cells are a seminal population of adaptive immune cel...

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

Near-infrared emitters (NIR) will be of crucial importance for a variety of biomedical, security and defense applications, as well as for (in)visible light communications and the internet-of-things (IoT). Researchers fro...

A new type of rocket thruster that could take humankind to Mars and beyond has been proposed by a physicist at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL).

Sizzling-hot rocks are rising up and pushing on the plates on either side of the Atlantic.

The oldest fossil flowers we have found are about 135 million years old, but a statistical analysis suggests flowering plants evolved as early as 250 million years ago

The Dyatlov Pass incident, which saw nine Russian mountaineers die in mysterious circumstances in 1959, has been the subject of many conspiracy theories, but now researchers say an unusual avalanche is to blame

Our thumbs allow us to use a variety of tools, from hammers to smartphones, and a new analysis of hominin fossils suggests they have a long history

The infamous Dyatlov Pass incident, where 9 hikers died under mysterious circumstances, just got its first scientific explanation after 60 years of speculation.

Phase transitions are a fundamental piece of physics and chemistry. We're all familiar with different phases of water, for example, but this idea of a system of particles changing what it looks like and how it behaves is...

In the past few years, scientists have hatched some pretty crazy-sounding schemes in the name of protecting Earth and its inhabitants. From building an underwater wall 120 kilometers long to try to save a glacier to clou...

Researchers have developed a new approach that improves the image quality and contrast for holographic displays. The new technology could help improve near-eye displays used for virtual and augmented reality applications...

Archaeologists have discovered a fantastical-looking, 1,500-year-old house in Turkey that was decorated with illusory wall paintings and terracotta tiles on the floor with puppy prints and possible chicken decorations pr...
