Sociability genes found in some spiders
A team of researchers at the University of Pennsylvania, Texas Tech University, Cornell University and Australian National University has found similar genes between species of spiders that have some degree of sociability. They have published their paper in the journal Nature Communications.
Adventurous bird personalities can help population cope with climate change
- ScienceDaily
- 22/11/28 16:13
The areas in the Wadden Sea where red knots, plump migratory birds, spend the winter are under pressure. The Wadden Sea is changing due to human influences such as mining for gas, tourism and due to sea level rise. Ecologists have studied how 'personalities' of individual red knots differ and affect the way they search for food. Individuals that are fast explorers and take the risk to forage in...
Optically analyzing local brain environment: Astrocytes' acid response in epileptic mice
- ScienceDaily
- 22/11/28 16:12
Researchers have shown that astrocytes in the mouse brain exhibit an acid response with intensified epileptic seizures. The astrocytes' acid response could lead to the amplification of excitatory neuronal signals and be the underlying drive for generating plasticity for epileptogenesis.
The whole in a part: Synchronizing chaos through a narrow slice of spectrum
- ScienceDaily
- 22/11/28 16:12
Engineers have uncovered some intricate effects arising when chaotic systems, which typically generate broad spectra, are coupled by conveying only a narrow range of frequencies from one to another. The synchronization of chaotic oscillators, such as electronic circuits, continues to attract considerable fascination due to the richness of the complex behaviors that can emerge. Recently,...
Making the most of quite little: Improving AI training for edge sensor time series
- ScienceDaily
- 22/11/28 16:12
Engineers have demonstrated a simple computational approach for improving the way artificial intelligence classifiers, such as neural networks, can be trained based on limited amounts of sensor data. The emerging applications of the internet of things often require edge devices that can reliably classify behaviors and situations based on time series. However, training data are difficult and...
New Green Revolution gene discovery sows hope of drought resilient wheat
- ScienceDaily
- 22/11/28 16:12
Researchers have discovered a new height-reducing gene Rht13 which means that seeds can be planted deeper in the soil giving access to moisture, without the adverse effect on seedling emergence seen with existing wheat varieties
DNA sequence enhances understanding origins of jaws
- ScienceDaily
- 22/11/28 16:12
Researchers have discovered and characterized a DNA sequence found in jawed vertebrates, such as sharks and humans, but absent in jawless vertebrates, such as lampreys. This DNA is important for the shaping of the joint surfaces during embryo development.
Protein shapes indicate Parkinson's disease
- ScienceDaily
- 22/11/28 16:12
Researchers have found that a set of proteins have different shapes in the spinal fluid of healthy individuals and Parkinson's patients. These could be used in the future as a new type of biomarker for this disease.

By dispersing seeds, animals can rapidly reestablish plant diversity in degraded forests.
Hydroacoustic signals help study impacts of underwater explosions off French coast
- ScienceDaily
- 22/11/28 16:12
A study of hydroacoustic, acoustic and seismic waves from underwater explosions off the French coast could help guide the disposal of unexploded World War II ordnance (UXO) in those waters, according to a new study.
Higher vitamin K intake linked to lower bone fracture risk late in life
- ScienceDaily
- 22/11/28 16:12
Research has revealed vitamin K1 can help reduce the risk of fractures in older populations -- especially hip fractures.
When cyclones and fires collide...

As strong winds and torrential rains inundate Australia's south-eastern coast, new research suggests that high intensity bushfires might not be too far behind, with their dual effects extending damage zones and encroaching on previously low-risk residential areas.
Mussel survey reveals alarming degradation of River Thames ecosystem since the 1960s
- ScienceDaily
- 22/11/28 16:12
Scientists replicated a 1964 River Thames survey and found that mussel numbers have declined by almost 95%, with one species -- the depressed river mussel -- completely gone.
Using math to better treat cancer
- ScienceDaily
- 22/11/28 16:12
Researchers have identified a new method for scheduling radiation therapy that could be as much as 22 percent more effective at killing cancer cells than current standard radiation treatment regimens.
Seagrass crucial to stemming the tide of coastal erosion
- ScienceDaily
- 22/11/28 16:12
Researchers show that seagrass can reduce cliff erosion by up to 70% thanks to its root mats binding the sand.
Green means GO! Ultra-violet means STOP!

- 22/11/28 16:12
A research group has revealed a new system that allows them to control the behavior of the nematode worm Caenorhabditis elegans, using two different animal opsins, a type of light-sensitive protein. The first opsin was expressed in the worms' sensory cells responsible for triggering avoidance behavior, making the worms move. This opsin was found to be approximately 7,000 times more sensitive to...
Ancient superpredator got big by front-loading its growth in its youth
- ScienceDaily
- 22/11/28 16:12
Whatcheeria, a six-foot-long salamander-like creature that lived 340 million years ago, was the T. rex of its time: the biggest, baddest predator in its habitat. A new study reveals how they grew to their 'giant' size: instead of growing slow and steady throughout their lives like many modern reptiles and amphibians, they did most of their growing when they were young.
Astrophysicists hunt for second-closest supermassive black hole
- ScienceDaily
- 22/11/28 16:12
As massive as the black hole at the center of the Milky Way, the behemoth is hosted by a dwarf galaxy less than 1 million light-years away. Invisible so far -- maybe not for long.
Earth's many new lakes
- ScienceDaily
- 22/11/28 16:12
The number of lakes on our planet has increased substantially in recent decades, according to a unique global survey of 3.4 million lakes. There has been a particular increase in the number of small lakes, which unfortunately, emit large amounts of greenhouse gas. The development is of great importance for Earth's carbon account, global ecosystems, and human access to water resources.
Chemotherapy could increase disease susceptibility in future generations
- ScienceDaily
- 22/11/28 16:12
A common chemotherapy drug could carry a toxic inheritance for children and grandchildren of adolescent cancer survivors, new research indicates. The study found that male rats who received the drug ifosfamide during adolescence had offspring and grand-offspring with increased incidence of disease. While other research has shown that cancer treatments can increase patients' chance of developing...
Australia falls short in Great Barrier Reef efforts: experts
Despite warnings, Australia's efforts to save the Great Barrier Reef still fall short of protecting the world's largest coral reef system from pollution and climate change, experts said Monday.
How women can reduce the risk of hip fracture
- ScienceDaily
- 22/11/28 16:08
Increasing intake of protein and drinking regular cups of tea or coffee is a way women could reduce their risk of suffering a hip fracture, according to new research. Food scientists have found that for women, a 25g a day increase in protein was associated with, on average, a 14% reduction in their risk of hip fracture. In a surprise twist, they also discovered that every additional cup of tea or...
Hawaii volcano, world's largest, erupts for first time in decades
Hawaii's Mauna Loa, the largest active volcano in the world, has erupted for the first time in nearly 40 years, US authorities said, as emergency crews went on alert early Monday.
Leading plastics scientists call for inclusion of all associated chemicals in global plastics treaty
Plastic pollution is a global health and environmental problem, with serious social and economic consequences. Without political intervention, the amount of plastic waste in the environment is expected to double by 2030 to around 53 million tons per year, according to the UNEP. UN member states have therefore agreed to open international negotiations with a view to drawing up a global plastics...
