Do 'bouncing universes' have a beginning?

A new study by physicists highlights one way that cyclic or 'bouncing' cosmologies fall flat. 'People proposed bouncing universes to make the universe infinite into the past, but what we show is that one of the newest types of these models doesn't work,' says a professor of physics.

Potential long-term treatment for asthma found

A possible way to tackle one of the underlying causes of asthma has been developed. In tests in mice, the researchers were able to virtually eliminate asthmatic symptoms within two weeks and return their airways to near normal.

Study finds genetic method for identifying hundreds of disease agents 'promising'

In the pursuit of accurate diagnoses for illnesses, doctors have traditionally used multiple methods -- including culturing patient samples on a wide variety of media, reviewing countless medical records and analyzing clinical data using complex mathematical algorithms -- to try to identify the bacterium, virus, fungus or other pathogen responsible for an infection.

CT scanner captures entire woolly mammoth tusk

Researchers successfully captured CT images of an entire woolly mammoth tusk. Researchers were able to do a full scan of the tusk in its entirety -- or in toto -- using a newer clinical CT scanner. The new technology allows for large-scale imaging without having to do multiple partial scans.

Banana peels make sugar cookies better for you

Banana peels aren't always destined for the trash or compost anymore. They're making their way onto people's plates, replacing pork in 'pulled peel' sandwiches and getting fried up into 'bacon.' And now, researchers show that incorporating banana peel flour into sugar cookie batter makes the treats more healthful. In taste tests, cookies enriched with some banana peel flour were more satisfying...

Stars determine their own masses

Using new simulations, astrophysicists discovered that star formation is a self-regulatory process. In other words, stars themselves set their own masses. This helps explain why stars formed in disparate environments still have similar masses.

Human-machine interfaces work underwater, generate their own power

Scientists describe the development of a type of wearable human-machine interface device that is stretchable, inexpensive, and waterproof. The device is based on a soft magnetoelastic sensor array that converts mechanical pressure from the press of a finger into an electrical signal. The device involves two main components: a layer that translates mechanical movement to a magnetic response and a...

Ultrasound could save racehorses from bucked shins

When racehorses enter training at about 2 years old, they can develop tiny stress fractures and new bone formations in their legs. This condition, called bucked shin, occurs in about 70% of the animals. Researchers have now developed a method to screen for bucked shin using ultrasound. Axial transmission, in which an ultrasound emitter and receiver are placed on the skin to induce and measure wave...

Realistic computer models of brain cells

Investigators have created the most bio-realistic and complex computer models of individual brain cells -- in unparalleled quantity. Their research details how these models could one day answer questions about neurological disorders -- and even human intellect -- that aren't possible to explore through biological experiments.

Body posture affects how oral drugs absorbed by stomach

A common method of administering drugs is orally, by swallowing a pill or capsule. But oral administration is the most complex way for the human body to absorb an active pharmaceutical ingredient, because the bioavailability of the drug in the gastrointestinal tract depends on the medication's ingredients and the stomach's dynamic physiological environment. Researchers have now employed a...

Hearing loss in dogs associated with dementia

A new study explores the connection between hearing loss and dementia in geriatric dogs. The work could aid in both treatment of aging dogs and in understanding the relationship between sensory loss and cognitive function in dogs.

Microrobotics in endodontic treatment, diagnostics

In a proof-of-concept study, researchers have shown that microrobots can access the difficult to reach surfaces of the root canal with controlled precision, treating and disrupting biofilms and even retrieving samples for diagnostics, enabling a more personalized treatment plan.

Concrete evidence: Simple method to improve the sustainability of construction

Researchers have improved the compressive strength and other properties of recycled concrete after high-pressure compaction. For example, one thermally treated sample exhibited >5× improvement compared with no thermal treatment. The results of this work will help minimize the carbon footprint of the construction industry by making maximum use of concrete that would otherwise be wasted.

Networking for food: Bats communicate and work together for more efficient foraging

Social hunting strategies are already well documented in many animal species when prey is distributed in an unpredictable way across the landscape. Researchers have now demonstrated for the first time that animals -- in this case the common noctule bat -- join together and form a mobile sensory network in order to increase their chances of finding their prey. The analyses show that predators can...

Future medical applications in drug design

Morphogens are the secreted molecules that pattern embryonic tissues. These molecules are important not only for the embryo during development, but also for the adult during tissue repair. However, the way these morphogens are distributed to ensure patterning occurs is still not fully understood. Using a combination of experiments and mathematical modeling, researchers learned more about the role...
