Study helps explain why motivation to learn declines with age

Science Daily - 4 hours 25 min ago
Neuroscientists have identified a brain circuit critical for learning to make decisions that require evaluating the cost or reward of an action. They showed this circuit is negatively affected by aging and in Huntington's disease.

Leaving more big fish in the sea reduces carbon dioxide emissions

Science Daily - 7 hours 8 min ago
Leaving more big fish -- like tuna, sharks, mackerel and swordfish -- in the sea reduces the amount of carbon dioxide released into the Earth's atmosphere. This is because when a fish dies in the ocean it sinks to the depths and sequestrates all the carbon it contains with it. This is a form of 'blue carbon'. Big fish are about 10 to 15 percent carbon.

Engineers have developed a drone with a feathered wing and tail that give it unprecedented flight agility.

Multi-drone system autonomously surveys penguin colonies

Science Daily - 7 hours 8 min ago
A new multi-drone imaging system was put to the test in Antarctica. The task? Documenting a colony of roughly 1 million Adélie penguins.

Juno data indicates 'sprites' or 'elves' frolic in Jupiter's atmosphere

Science Daily - 7 hours 8 min ago
An instrument on NASA's Juno mission spacecraft may have detected transient luminous events -- bright flashes of light in the gas giant's upper atmosphere.

Using a volcano's eruption 'memory' to forecast dangerous follow-on explosions

Science Daily - 28/10/2020
Stromboli, the 'lighthouse of the Mediterranean', is known for its low-energy but persistent explosive eruptions, behaviour that is known scientifically as Strombolian activity. Occasionally, however, more intense and sudden explosions occur, most recently in July and August last year (2019). These are known as 'Strombolian paroxysms'. During such events several of Stromboli's craters are active simultaneously and much greater volumes of pyroclastic materials are erupted than is usual for the volcano.

Researchers map genomes of agricultural 'monsters'

Science Daily - 28/10/2020
Biologists are unlocking the genomes of creepy agricultural pests like screwworms that feast on livestock from the inside out and thrips that transmit viruses to plants.

Astronomers discover activity on distant planetary object

Science Daily - 28/10/2020
A team of astronomers, earlier this year announced their discovery of activity emanating from Centaur 2014 OG392, a planetary object first found in 2014. As a result of the team's discovery, the Centaur has recently been reclassified as a comet, and will be known as 'C/2014 OG392 (PANSTARRS).'

Models for potential precursors of cells endure simulated early-Earth conditions

Science Daily - 28/10/2020
Membraneless compartments -- models for a potential step in the early evolution of cells -- have been shown to persist or form, disappear, and reform in predictable ways through multiple cycles of dehydration and rehydration.

New dataset provides county-level exposure numbers for tropical cyclones, human health

Science Daily - 28/10/2020
The new open source data set can be used for epidemiological research on tropical cyclones.

Cracking the secrets of dinosaur eggshells

Science Daily - 28/10/2020
Since the famous discovery of dinosaur eggs in the Gobi Desert in the early 1920s, the fossilized remains have captured the imaginations of paleontologists and the public, alike. Although dinosaur eggs have now been found on every continent, it's not always clear to scientists which species laid them. Now, researchers have narrowed down the list for an unknown eggshell from Mexico by comparing its microstructure and composition with four known samples.

A patch that could help heal broken hearts

Science Daily - 28/10/2020
According to the American Heart Association, heart disease is the leading cause of death worldwide in recent years. During a heart attack, or myocardial infarction (MI), a blocked artery and the resulting oxygen deprivation cause massive cardiac cell death, blood vessel impairment and inflammation. Now, researchers have developed a cardiac patch with tiny engineered blood vessels that improved recovery from MI in rats and pigs.

ISRO to launch earth observation satellite EOS-01 on November 7

Secrets of 'smasher shrimp' property ladder revealed

Science Daily - 28/10/2020
Mantis shrimps carefully survey burrows before trying to evict rivals, new research shows.

Paracetamol poisonings up

Science Daily - 28/10/2020
In 2003, the painkiller paracetamol became available in Switzerland in tablets with a higher dose of the active ingredient. This correlates with an increase in cases of paracetamol poisoning in the country, as a data analysis shows.

Genetic analysis system yields new insights into bacterial pneumonia

Science Daily - 28/10/2020
A team of infectious disease researchers has developed a new method to identify virulence genes in Streptococcus pneumoniae, the leading cause of bacterial pneumonia. Using this technique in a mouse model of pneumonia, they were able to gain new insights into the progression of the disease and its interaction with the flu virus.

Device takes us closer to high-performing wearable and eco-disposable AI electronics

Science Daily - 28/10/2020
Engineers have unveiled a device with unique functionality that could signal the dawn of a new design philosophy for electronics, including next-generation wearables and eco-disposable sensors.

Weak equivalence principle violated in gravitational waves

Science Daily - 28/10/2020
New research proves theoretically that the Weak Equivalence Principle can be violated by quantum particles in gravitational waves - the ripples in spacetime caused by colossal events such as merging black holes.

Climate change drives plants to extinction in the Black Forest in Germany

Science Daily - 28/10/2020
Climate change is leaving its mark on the bog complexes of the German Black Forest. Due to rising temperatures and longer dry periods, two plant species have gone extinct over the last 40 years. The populations of many others have decreased by one third. According to a new study, more species could become extinct in the next couple of decades.

Renewable energy targets can undermine sustainable intentions

Science Daily - 28/10/2020
Renewable energy targets (RETs) may be too blunt a tool for ensuring a sustainable future, according to new research.
