Scientists have employed novel statistical methods to reveal the extent of biodiversity loss in Singapore over the past two centuries. The study paints the most accurate picture to date of the ecological impact of deforestation and urban development in the tropical city-state. From a comprehensive dataset, the study estimated that Singapore has lost 37 per cent of its species.
Meteorites are fragments of asteroids which find their way to Earth as shooting stars and provide information on the origins of our solar system. A team of researchers has examined the so-called Winchcombe meteorite and demonstrated the existence in it of nitrogen compounds such as amino acids and heterocyclic hydrocarbons -- without applying any chemical treatment and by using a new type of detector design.
Researchers found that when mice were fed a high-fat diet, mitochondria within their fat cells broke apart and were less able to burn fat, leading to weight gain. They also found they could reverse the effect by targeting a single gene, suggesting a new treatment strategy for obesity.
For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse work? Through a series of experiments, a team of mathematicians has figured out how flowing fluids exert forces and move structures, thereby revealing the answer to this long-standing mystery.
Researchers have discovered that a brain area preserved through evolution, called the superior colliculus, is more crucial for vision than we thought.
An important question for policymakers worldwide is how to make climate and environmental policies acceptable among the populations. A new study sheds light on the preferences in five East African countries. The study shows, among others, that education and information about how revenues from carbon taxes are used are important factors.
Artificial intelligence using neural networks performs calculations digitally with the help of microelectronic chips. Physicists have now created a type of neural network that works not with electricity but with so-called active colloidal particles.The researchers describe how these microparticles can be used as a physical system for artificial intelligence and the prediction of time series.
Researchers mapped genetic blueprints for 51 species including cats, dolphins, kangaroos, penguins, sharks, and turtles, a discovery that deepens our understanding of evolution and the links between humans and animals. The researchers developed novel algorithms and computer software that cut the sequencing time from months -- or decades in the case of the human genome -- to a matter of days.
Allegations of research fakery at a leading cancer center have turned a spotlight on scientific integrity and the amateur sleuths uncovering image manipulation in published research
Scientific discourses focussing on the Sun, planets, black holes and beyond will be held from January 31 to February 4
A study has reported making deep-learning approaches to drug discovery ‘explainable’, a significant step
Ever since taking control of the House in 2023, Republicans have pushed to impeach Mayorkas
Pet owners forced to be separated from their animals in crisis situations, including those who are victims of domestic violence, are suffering from a lack of support services needed to protect them.
The satellite is designed for enhanced meteorological observations and monitoring of land and ocean surfaces for weather forecasting and disaster warning.
The teams said they were worried governments and funders may pull back from such surveillance, despite its potential to better monitor many infectious diseases, from malaria to cholera.
At its heart is whole-genome sequencing, a tool that can sequence a person’s DNA in its entirety in a single comprehensive test
January 28, 1986 will forever be remembered in the history of space exploration as the day when the Challenger disaster took place. NASA’s second shuttle to reach space, Challenger exploded after liftoff during its 10th launch. A.S.Ganesh takes a look at the Challenger disaster and its aftermath…
While samples were collected and measured for maximum radius of 30 km of each nuclear plant, the concentrations of fission products beyond 5 km radius was below the minimum detectable activity of the instruments used
