Unique type of object discovered in our solar system

ScienceDaily News - 3 hours ago
Astronomers have observed the intriguing characteristics of an unusual type of object in the asteroid belt between Mars and Jupiter: two asteroids orbiting each other and exhibiting comet-like features, including a bright coma and a long tail. This is the first known binary asteroid also classified as a comet.

Plants combine color and fragrance to procure pollinators

ScienceDaily News - 3 hours 14 sec ago
Who knew that it's possible to predict the fragrance of a flower by looking at its color? This is true for many of the 41 insect-pollinated plant species growing in a Phrygana scrubland habitat on the Greek island of Lesbos.

Wave Glider surfs across stormy Drake Passage in Antarctica

ScienceDaily News - 3 hours 26 sec ago
A hardy ocean drone made a first-ever attempt to surf across Antarctica's stormy Drake Passage gathering data about ocean mixing.

Species abundance: Winter restricts innovation

ScienceDaily News - 4 hours 29 min ago
Why are there so many more species in the tropics? The 'storage effect' is stronger there than in temperate forests.

Bite force research reveals dinosaur-eating frog

ScienceDaily News - 4 hours 29 min ago
Scientists say that a large, now extinct, frog called Beelzebufo that lived about 68 million years ago in Madagascar would have been capable of eating small dinosaurs. The conclusion comes from a study of the bite force of South American horned frogs from the living genus Ceratophrys, known as Pacman frogs for their characteristic round shape and large mouth, similar to the video game character Pac-Man.

Animal acoustic activity decline shows forest fire pollution wreaks havoc on wildlife

ScienceDaily News - 4 hours 29 min ago
Forest fires in Southeast Asia during the El Niño droughts of 2015 caused considerable disruption to the biodiversity of the region due to the smoke-induced 'haze' they created, according to new research.

New concept of terrestrial planet formation

ScienceDaily News - 4 hours 29 min ago
Scientists are proposing a new way of understanding the cooling and transfer of heat from terrestrial planetary interiors and how that affects the generation of the volcanic terrains that dominate the rocky planets.

World's first 'molecular robot' capable of building molecules

ScienceDaily News - 4 hours 29 min ago
Scientists have created the world's first 'molecular robot' that is capable of performing basic tasks including building other molecules.

Dinosaur evolution: Lumbering giants had agile ancestors

ScienceDaily News - 4 hours 29 min ago
The best known sauropod dinosaurs were huge herbivorous creatures, whose brain structures were markedly different from those of their evolutionary predecessors, for the earliest representatives of the group were small, lithe carnivores.

Oxytocin turns up the volume of your social environment

ScienceDaily News - 4 hours 30 min ago
A new study shows that the so-called 'love hormone' oxytocin can intensify negative as well as positive experiences.

Parents: How you manage conflict has an impact on your kids

ScienceDaily News - 4 hours 30 min ago
It's not always bad for children to be exposed to their parents' disagreements. It's how those disagreements are handled that really matters, according to a new study.

Newly ID'd role of major Alzheimer's gene suggests possible therapeutic target

ScienceDaily News - 4 hours 30 min ago
A new role has been identified for the major Alzheimer's risk factor ApoE4, suggesting that targeting the protein may help treat the disease. Researchers show that ApoE4 exacerbates the brain damage caused by toxic tangles of a different Alzheimer's-associated protein: tau. In the absence of ApoE, tau tangles did very little harm to brain cells.

Scientists make atoms-thick 'Post-It notes' for solar cells and circuits

ScienceDaily News - 4 hours 30 min ago
A new study describes an innovative method to make stacks of semiconductors just a few atoms thick. The technique offers scientists and engineers a simple, cost-effective method to make thin, uniform layers of these materials, which could expand capabilities for devices from solar cells to cell phones.

Brain cancer growth halted by absence of protein

ScienceDaily News - 4 hours 30 min ago
The growth of certain aggressive brain tumors can be halted by cutting off their access to a signaling molecule produced by the brain's nerve cells, according to a new study.

Millions of new genes in human microbiome

ScienceDaily News - 4 hours 30 min ago
A new study of the human microbiome has uncovered millions of previously unknown genes from microbial communities in the human gut, skin, mouth, and vaginal microbiome, allowing for new insights into the role these microbes play in human health and disease.

Genome editing reveals role of gene important for human embryo development

ScienceDaily News - 4 hours 30 min ago
Researchers have used genome editing technology to reveal the role of a key gene in human embryos in the first few days of development. This is the first time that genome editing has been used to study gene function in human embryos, which could help scientists to better understand the biology of our early development.

Guess who? Facial expressions can cause confusion

ScienceDaily News - 6 hours 11 min ago
Photos of the same person can look substantially different. For example, your passport photo may look quite different from your driving license, or your face in holiday photos. Research has shown when photos of an individual's face are judged too dissimilar to go together, people will tend to think they show several different identities. Scientists have tested this concept further by exploring what happens when the photos show faces with different expressions.

Spinning a lighter, safer electrode

ScienceDaily News - 6 hours 11 min ago
A fabric-like material electrode has been created that could help make energy storage devices -- batteries and supercapacitors -- faster and less susceptible to leaks or disastrous meltdowns. Their design for a new supercapacitor, which looks something like a furry sponge infused with gelatin, offers a unique alternative to the flammable electrolyte solution that is a common component in these devices.

Midlife depression may stem from tension with mothers and siblings, study finds

ScienceDaily News - 6 hours 11 min ago
Relationships with our mothers and siblings continue to have an effect on our well-being, particularly at midlife. A new study found that tension with our mothers and siblings, similar to our spouses, is associated with symptoms of depression.

Smokers who quit have metabolite levels that resemble those of nonsmokers

ScienceDaily News - 6 hours 11 min ago
Even after years of smoking, the body has a remarkable ability to repair itself. Now in a study shows that certain metabolic changes occur soon after quitting, and these changes could help explain how some ill-effects of smoking might be reversible.
