Reinforcement learning expedites 'tuning' of robotic prosthetics

Researchers have developed an intelligent system for 'tuning' powered prosthetic knees, allowing patients to walk comfortably with the prosthetic device in minutes, rather than the hours necessary if the device is tuned by a trained clinical practitioner. The system is the first to rely solely on reinforcement learning to tune the robotic prosthesis. from Latest Science News -- ScienceDaily http://bit.ly/2MfgqlM

Body-painting protects against bloodsucking insects

A study by researchers from Sweden and Hungary shows that white, painted stripes on the body protect skin from insect bites. It is the first time researchers have successfully shown that body-painting has this effect. Among indigenous peoples who wear body-paint, the markings thus provide a certain protection against insect-borne diseases. from Latest Science News -- ScienceDaily http://bit.ly/2FHEUmy

Combination therapy treats leishmaniasis, HIV patients

Coinfection with visceral leishmaniasis (VL) and human immunodeficiency virus (HIV) has been observed in at least 35 countries on four continents and requires special case management. Currently, the World Health Organization recommends AmBisome monotherapy for treatment. Now, researchers have showed that a combination therapy of AmBisome and miltefosine is more effective. from Latest Science News -- ScienceDaily http://bit.ly/2FKW82B

Individual lichens can have up to three fungi

Individual lichens may contain up to three different fungi, according to new research from an international team of researchers.

Stress fracture? Your foot hitting pavement wasn't the main problem

It starts as a persistent and irritating pain in the foot or lower leg, then it gets more intense, maybe with swelling, and soon a runner knows she's being sidelined by one of the most common running injuries: a stress fracture. These tiny cracks in the bone can halt training for months or even end a sports season. A segment of the multibillion-dollar wearables industry aims to save potential victims from this fate, but an engineering professor found a major problem: the devices are measuring the wrong thing. from Latest Science News -- ScienceDaily http://bit.ly/2QVnjJR

Size matters: To livebearer fish, big fins are a big deal

Biologists studied the evolution of 40 molly and Limia species, and concluded dorsal fin displays arose first for males to compete with other males, only later being used in courtship displays to females. These changes in fin function went hand in hand with enlargement of the male dorsal fin. The fins reached extreme sizes in a few species and appear to be associated with rapid evolution, especially in mollies. from Latest Science News -- ScienceDaily http://bit.ly/2QW1xpe

Scientists search for new methods to cure neurodegenerative diseases

Most neurons in the human brain are generated from neural stem cells during embryonic development. After birth, a small reservoir of stem cells remains in the brain that keeps on producing new neurons throughout life. However, the question arises as to whether these new neurons really support brain function? And if so, can we improve brain capacity by increasing the number of neurons? A research group has now answered these questions. from Latest Science News -- ScienceDaily http://bit.ly/2QWCR02

Blister fluid could help diagnose burn severity

Severe burns can leave physical and psychological scars, especially in children. When a burn patient enters the clinic, doctors use factors such as the depth and size of the burn, as well as the time required for skin healing -- or re-epithelialization -- to determine the best course of treatment. Now, researchers have found another, possibly more accurate way to classify burn severity: analyzing proteins in blister fluid. from Latest Science News -- ScienceDaily http://bit.ly/2CwvYNQ

The cytoskeleton of neurons has been found to be involved in Alzheimer's disease

A researcher has participated in a study describing what it is during the early stages of Alzheimer's that triggers the loss of dynamics and subsequent impairment of the dendritic spines, the compartments of the neurons responsible for receiving nerve impulses from other neurons. The role played by the actin cytoskeleton of these compartments and how it responds in the presence of beta-amyloid peptides, the component most commonly associated with Alzheimer's, have been described. from Latest Science News -- ScienceDaily http://bit.ly/2W8hb4S

How our cellular antennas are formed

Most of our cells contain an immobile primary cilium. The 'skeleton' of the cilium consists of microtubule doublets, which are 'pairs' of proteins essential for their formation and function. Scientists have developed an in vitro system capable of forming microtubule doublets, and have uncovered the mechanism and dynamics of their assembly. Their study reveals the crucial role of tubulin, a real building block, in preventing the uncontrolled formation of ciliary structures. from Latest Science News -- ScienceDaily http://bit.ly/2FFgcDj

Scientists find increase in asteroid impacts on ancient Earth by studying the Moon

A team of scientists has determined the number of asteroid impacts on the Moon and Earth increased by two to three times starting around 290 million years ago. Previous theories held that there were fewer craters on both objects dating back to before that time because they had disappeared due to erosion. The new findings claim that there were simply fewer asteroid impacts during that earlier period. from Latest Science News -- ScienceDaily http://bit.ly/2QWVpgo

Can a critic-turned-believer sway others? The case of genetically modified foods

When an advocate for one side of an issue announces that he or she now believes the opposite, can that message affect others' views? Research shows that such a conversion message can influence public attitudes.

Brain cells that make pain unpleasant

If you step on a tack, neurons in your brain will register two things: that there's a piercing physical sensation in your foot, and that it's not pleasant.

Saturn hasn't always had rings

In its last days, the Cassini spacecraft looped between Saturn and its rings so that Earth-based radio telescopes could track the gravitational tug of each. Scientists have now used these measurements to determine the mass of the rings and estimate its age, which is young: 10-100 million years. This supports the hypothesis that the rings are rubble from a comet or Kuiper Belt object captured late in Saturn's history. from Latest Science News -- ScienceDaily http://bit.ly/2W3czwy

New findings reveal surprising role of the cerebellum in reward and social behaviors

A study in rodents found that the brain's cerebellum -- known to play a role in motor coordination -- also helps control the brain's reward circuitry. Researchers found a direct neural connection from the cerebellum to the ventral tegmental area (a brain area long known to be involved in reward processing and encoding). The findings shed light on the brain circuits critical to the affective and social dysfunction seen across multiple psychiatric disorders. from Latest Science News -- ScienceDaily http://bit.ly/2QWRxMm

Proposed engineering method could help make buildings and bridges safer

Researchers discovered that the distance between dislocations in nanolayer interfaces of pearlite can determine how much the material can stretch or contract without breaking (ductility).
