Paradigm shift needed for designing tsunami-resistant bridges

Monday December 17th, 2018 05:58:58 PM
Researchers argue in a new study that a paradigm shift is needed for assessing bridges' tsunami risk.

Baboon sexes differ in how social status gets 'under the skin'

Monday December 17th, 2018 05:58:55 PM
A growing body of evidence shows that those at the bottom of the socioeconomic ladder are more likely to die prematurely than those at the top. The pattern isn't unique to humans: Across many animals, the lower an individual's social status, the worse their health. But new research in baboons suggests that the nature of the status-health relationship depends on whether an individual has to fight for status, or it's given to them.

Discovered: The most-distant solar system object ever observed

Monday December 17th, 2018 05:00:54 PM
A team of astronomers has discovered the most-distant body ever observed in our solar system. It is the first known solar system object that has been detected at a distance that is more than 100 times farther than Earth is from the sun.

Communication between neural networks

Monday December 17th, 2018 05:00:46 PM
Researchers are proposing a new model to explain how neural networks in different brain areas communicate with each other.

Drivers who can 'bid' for parking spaces may improve parking options around the world

Monday December 17th, 2018 05:00:40 PM
Researchers have developed a parking algorithm that allows drivers to 'bid' for a curbside spot in urban areas. A smartphone app that uses the algorithm can offer a practical solution to the problem of bottleneck parking in low supply areas and empty lots outside the immediate sphere of demand.

Birds can mistake some caterpillars for snakes; can robots help?

Monday December 17th, 2018 05:00:38 PM
Researchers witnessed a hummingbird defending its nest from what it interpreted to be a snake, but was actually a caterpillar of the moth Oxytenis modestia. 

Saturn is losing its rings at 'worst-case-scenario' rate

Monday December 17th, 2018 05:00:32 PM
New NASA research confirms that Saturn is losing its iconic rings at the maximum rate estimated from Voyager 1 and 2 observations made decades ago. The rings are being pulled into Saturn by gravity as a dusty rain of ice particles under the influence of Saturn's magnetic field.

Injection improves vision in a form of childhood blindness

Monday December 17th, 2018 05:00:30 PM
A new treatment for patients with a form of congenital retinal blindness has shown success in improving vision, according to new results.

Do you know the carbon footprint of your food choices?

Monday December 17th, 2018 05:00:27 PM
Consumers greatly underestimate the energy consumption and greenhouse gas emissions associated with their food choices, but they'll favor items with a lower carbon footprint if they're given clear information on the label, according to new research.

The impacts of whale shark mass tourism on the coral reefs in the Philippines

Monday December 17th, 2018 05:00:22 PM
Whale shark tourism in Tan-awan, Oslob, Philippines has led to degradation of the local coral reef ecosystem.

Pressure tuned magnetism paves the way for novel electronic devices

Monday December 17th, 2018 05:00:20 PM
Using very sensitive magnetic probes, an international team of researchers has found surprising evidence that magnetism which emerges at the interfaces between non-magnetic oxide thin layers can be easily tuned by exerting tiny mechanical forces. This discovery provides a new and unexpected handle to control magnetism, thus enabling denser magnetic memory, and opens new and unexpected routes for developing novel oxide-based spintronic devices.

Passive exposure alone can enhance the learning of foreign speech sounds

Monday December 17th, 2018 05:00:17 PM
Ability to understand and subsequently speak a new language requires the ability to accurately discriminate speech sounds of a given language. When we start to learn a new language the differences between speech sounds can be very difficult to perceive. With enough active practice the ability to discriminate the speech sounds enhances.

Advancing the description of 'mysterious' water to improve drug design

Monday December 17th, 2018 05:00:14 PM
Interactions with water dominate how drug molecules bind to targets, but it's tricky to model these interactions, limiting the accuracy of drug design. Scientists have now described a novel approach to building a new description of water (known as a force field) and demonstrating its accuracy.

Species at the extremes of the food chain evolve faster, study says

Monday December 17th, 2018 05:00:12 PM
Reef fish species at the extremes of the food chain -- those that are strict herbivores or strict fish predators -- evolve faster than fish species in the middle of the food chain with a more varied diet, according to a new study.

One type of brain cell may invite Alzheimer's

Monday December 17th, 2018 04:57:56 PM
Researchers found that excitatory neurons -- those that are more likely to trigger an action (as opposed to inhibitory neurons, which are less likely to prompt neural activity) -- are more vulnerable to accumulations of abnormal tau protein, which is increasingly being implicated in Alzheimer's disease.

Stop that clot! Quantitative assessment of the blood coagulation cascade

Monday December 17th, 2018 03:59:30 PM
Thrombosis is a harmful activation of the clotting process, which is associated with the occurrence of blood vessel-related diseases. Pathological enhancement of the clotting cascade causes thrombosis, and activated factor X (FXa) is pivotal to this process. Researchers showed that dielectric blood coagulometry provided an easy to use method to detect changes in FXa activity in the presence of various drugs that inhibit the actions of FXa.

Adventures in phase space: Unified map on plastic and elastic glasses

Monday December 17th, 2018 03:59:20 PM
A research team has simulated glassy colloidal solids to understand their mechanical and failure properties. Under strain, the hard-sphere glasses deformed elastically (reversibly), partly plastically (irreversibly), or underwent yielding or jamming. The size of the elastic and plastic zones on the phase diagram, and the nature of failure, depended on how deeply the glasses were annealed. A unified framework for amorphous solid rheology will have applications across technology and biology.

Neuroscience-protein that divides the brain

Monday December 17th, 2018 03:59:15 PM
A recent study describes the role of a molecule, Netrin, in creating borders inside the brain to compartmentalize the functions of the brain.

Data storage using individual molecules

Monday December 17th, 2018 03:59:13 PM
Researchers have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal 'small', the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Microtube with built-in pump

Monday December 17th, 2018 03:59:04 PM
Driven by natural or artificial sunlight, a novel 'microtube pump' transports water droplets over long distances. The pump consists of a tube whose properties can be changed asymmetrically through irradiation. This results in capillary forces and a wettability gradient in the inner wall which work together to accelerate the water droplets to exceptional high speeds.
