As we use resources, such as coal, oil, natural gas, copper, silicon and aluminum, to power massive computer farms and process digital information, our technological progress is redistributing Earth's matter from physica...

(American Institute of Physics) In Physics of Fluids, scientists report calculations with a model of a conical-shaped root canal inside a tooth. A crucial step in this common dental procedure is irrigation, or rinsing, o...

Jealousy can be a useful tool in maintaining friendships, a new study report. Feelings of jealousy were linked to the value of the friendship and motivated behaviors to retain the relationship.

The optical vortex plays an increasingly important role in optical information processing. As an information carrier, it improves the capacity of channels and offers an independent aspect for analysis--different from pol...

Researchers have devised techniques that allowed them to successfully replace dysfunctional microglia.

Aging may alter neural processes for remembering continuous real-world experiences and segmenting memories.

Only late-stage human trials can show that a vaccine is both safe and effective.

Analyzing nasal discharge could be a new tool in diagnosing and monitoring the progression of Alzheimer's disease. Researchers found certain Alzheimer's related proteins can be detected in nasal discharge.

Along with the COVID-19 pandemic, the world has faced an "infodemic" of misinformation.

Cannabidiol (CBD) increases cerebral blood flow to areas of the brain associated with memory processing, specifically the hippocampus. The findings identify a potential mechanism for the use of CBD to treat disorders ass...

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

Signatures of brain activity in infants can predict autism symptoms at 18 months of age. In infants who later received a diagnosis of ASD, researchers noted decreased connectivity between frontal brain regions. The infan...

Of ever-increasing concern for operating a tactical communications network is the possibility that a sophisticated adversary may detect friendly transmissions. Army researchers developed an analysis framework that enable...

Scientists at Stockholm University have discovered that water can exhibit a similar behavior to that of a liquid crystal when illuminated with laser light. This effect originates by the alignment of water molecules, whic...

The country will reinstate temporary COVID-19 restrictions.

Most medical AI systems make treatment recommendations based on correlations between symptoms and illnesses - a new AI system uses causation instead, like doctors do

Regular bricks can be turned into energy storage devices through a process that uses their red pigment to create a network of conductive fibres inside the bricks

It's unclear what killed this roughly 15-year-old male woolly mammoth at least 10,000 years ago.

The remains of several timber circles constructed over 4,500 years ago have been discovered at the Perdigões complex archaeological site in Portugal.

Scientists used computational fluid dynamics to determine the effect of temperature on root canal cleaning efficiency. Higher temperatures can, to a point, improve cleansing, but this benefit falls off if the temperature...

Since the COVID-19 virus spreads through respiratory droplets, researchers in India set out to explore how droplets deposited on face masks or frequently touched surfaces, like door handles or smartphone touch screens, d...

An AI has learned to recognise objects using video captured by a head-mounted camera worn by young children for a few hours per week over their first 3 years of life
