Measuring quality of life after pediatric kidney transplant

After receiving a kidney transplant, children may experience quality-of-life difficulties that underscore the importance of screening transplant recipients for psychosocial function, according to Children's research presented May 4, 2019, during the 10th Congress of the International Pediatric Transplant Association.

Limiting oxygen could control symptoms of Friedreich's ataxia

Friedreich's ataxia (FRDA) is a rare, inherited disorder that causes progressive damage to the nervous system. This damage leads to ataxia—problems with movement and coordination—that worsens with time. Other symptoms, such as loss of strength and sensation in the arms and legs, muscle stiffness, and impaired speech, hearing, and vision, can also result. New research in cell models and in mice suggests that limited environmental oxygen, known as hypoxia, might one day help FRDA patients, although the safety of doing so is yet unknown.

Study shows native plants regenerate on their own after invasive shrubs are removed

Invasive shrubs have become increasingly prevalent in the deciduous forests of eastern North America—often creating a dense understory that outcompetes native plants. Many land managers would like to remove the invaders, but worry about what happens afterwards. Will they need to launch a costly remediation program to reestablish native plant communities?

Atlas is rockstar cross-stepper over tricky terrain

Robot enthusiasts were sending up cheers this month to the team advancing Atlas into an even more human-like walker through obstacles including a bunch of cinder blocks and a balance beam. They have turned Atlas into the very credible hulk, who wins the spotlight with its display of walking, which was recorded May 1.

Manipulating superconductivity using a 'mechanic' and an 'electrician'

In strongly correlated materials such as cuprate high-temperature superconductors, superconductivity can be controlled either by changing the number of electrons or by changing the kinetic energy, or transfer energy, of electrons in the system. Although a large number of strongly correlated materials have been examined with different parameters to understand the mechanism of superconductivity, the range of parameter control is always limited. A versatile experimental method to achieve simultaneous control of the number and the transfer energy of the electrons has been long desired.

A friction reduction system for deformable robotic fingertips

Researchers at Kanazawa University have recently developed a friction reduction system based on a lubricating effect, which could have interesting soft robotics applications. Their system, presented in a paper published in Taylor & Francis' Advanced Robotics journal, could aid the development of robots that can efficiently manipulate objects under both dry and wet conditions.

Trial remedies racial disparities in treatment for early-stage lung and breast cancer patients

Results from a study published in the Journal of the National Medical Association show that a pragmatic system-based intervention within cancer treatment centers can nearly eliminate existing disparities in treatment and outcomes for black patients with early-stage lung and breast cancer. The treatment completion rates before this intervention were 87.3 percent for white patients versus 79.8 percent for black patients. With the intervention in place, treatment completion climbed to 89.5 percent for white patients and 88.4 percent for black patients.

A face-following robot arm with emotion detection

Researchers at Universitat Autònoma de Barcelona (UAB) have recently developed a face-following robotic arm with emotion detection inspired by Pixar Animation Studios' Luxo Jr. lamp. This robot was presented by Vernon Stanley Albayeros Duarte, a computer science graduate at UAB, in his final thesis.

A surprising experiment opens the path to new particle manipulation methods

Researchers at Aalto University have discovered a surprising phenomenon that changes how we think about how sound can move particles. Their experiment is based on a famous experiment recognisable from high school science classrooms worldwide—the Chlandni Plate experiment, where particles move on a vibrating surface. The experiment was first performed in 1787 by Ernst Chladni, who is now known as the father of acoustics. Chladni's experiment showed that when a plate is vibrating at a certain frequency, heavy particles move towards the regions with less vibration, called nodal lines. This experiment has been extensively repeated during the centuries since, and has shaped the common understanding of how heavy particles move on a vibrating plate. But researchers at Aalto University have now shown a case where heavy particles move towards the regions with more vibrations, or antinodes. "This is a surprising result, almost a contradiction to common beliefs," says Professor Quan Zhou.

Researchers discover the Achilles' heel of an aggressive brain cancer

Glioblastoma is the most prevalent and also the most lethal type of brain tumour in adults, with no curative treatment currently available. Glioblastomas cannot be surgically completely excised, as the tumour cells are adept at invading tissues and spreading around the brain. In addition, glioblastoma cells are extremely resistant to existing drug therapies.

New study shows scientists who selfie garner more public trust

Many scientists today have embraced social media as tools to communicate their research and to engage broader audiences in scientific discovery and its outcomes. But the rise of the "social media scientist" has also led communicators and scholars to ask an important and often overlooked question: Do people trust the scientists who show up in their social media feeds?
