Astronomers spot 18 black holes gobbling up nearby stars

29/01/2024
Scientists have identified 18 new tidal disruption events (TDEs) -- extreme instances when a nearby star is tidally drawn into a black hole and ripped to shreds. The detections more than double the number of known TDEs in the nearby universe.

Sound-powered sensors stand to save millions of batteries

29/01/2024
Researchers are developing a new type of sensor that reacts to certain sound waves, causing it to vibrate. The sensor is a metamaterial that acquires its special properties through the structuring of the material. Passive sound-sensitive sensors could be used to monitor buildings, earthquakes or certain medical devices and save millions of batteries.

Excavated dolmen in Sweden one of the oldest in Scandinavia

29/01/2024
The first analysis results now confirm that the grave in Tiarp is one of the oldest stone burial chambers in Sweden. The researchers noted that some parts of the people buried in the grave are missing, such as skulls and thigh bones, posing intriguing questions for archaeologists.

First-ever sighting of a live newborn great white

29/01/2024
Great whites, the largest predatory sharks in the world with the most fatal attacks on humans, are tough to imagine as newborn babies. That is partially because no one has seen one in the wild, it seems, until now.

Destroying tumor cells with calcium

29/01/2024
Calcium ions are essential for cells, but can be toxic in higher concentrations. A team of researchers has now designed and prepared a combination drug that kills tumor cells by modulating the calcium influx into the cell. An external calcium source is not necessary because only the calcium ions already present in the tumor tissue are used, according to a new study.

Expert warns red light myopia therapy can injure retina

29/01/2024
An optometry researcher is warning that the use of low-level red-light therapy as a method to control nearsightedness may cause injury to the retina, especially in children.

High-efficiency carbon dioxide electroreduction system reduces our carbon footprint and progressing carbon neutrality goals

29/01/2024
Global warming continues to pose a threat to human society and the ecological systems, and carbon dioxide accounts for the largest proportion of the greenhouse gases that dominate climate warming. To combat climate change and move towards the goal of carbon neutrality, researchers have developed a durable, highly selective and energy-efficient carbon dioxide (CO2) electroreduction system that can convert CO2 into ethylene for industrial purposes to provide an effective solution for reducing CO2 emissions.

Researchers control biofilm formation using optical traps

29/01/2024
Researchers showed that biofilm formation can be controlled with laser light in the form of optical traps. The findings could allow scientists to harness biofilms for various bioengineering applications.

Playing an instrument linked to better brain health in older adults

29/01/2024
Engaging in music throughout your life is associated with better brain health in older age, according to a new study. Scientists working on PROTECT, an online study open to people aged 40 and over, reviewed data from more than a thousand adults over the age of 40 to see the effect of playing a musical instrument -- or singing in a choir -- on brain health.

Robot trained to read braille at twice the speed of humans

29/01/2024
Researchers have developed a robotic sensor that incorporates artificial intelligence techniques to read braille at speeds roughly double that of most human readers.

Scientists develop novel method to estimate biodiversity loss in Singapore over the past two centuries

29/01/2024
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.

Cosmic building blocks of life discovered through the electron microscope

29/01/2024
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.

How obesity dismantles our mitochondria

29/01/2024
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.

How does a 'reverse sprinkler' work? Researchers solve decades-old physics puzzle

29/01/2024
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.

Old area in the brain turns out to be more important than expected

29/01/2024
Researchers have discovered that a brain area preserved through evolution, called the superior colliculus, is more crucial for vision than we thought.

Education and information can increase the acceptance of climate policies

29/01/2024
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.

Utilizing active microparticles for artificial intelligence

29/01/2024
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 map genome for cats, dolphins, birds, and dozens of other animals

29/01/2024
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.

New study reveals the profound impact of forced separation between humans and their pets

29/01/2024
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.
