Austrian and Chinese scientists have succeeded in teleporting three-dimensional quantum states for the first time. High-dimensional teleportation could play an important role in future quantum computers. Researchers from the Austrian Academy of Sciences and the University of Vienna have experimentally demonstrated what was previously only a theoretical possibility.
Biochemists discover new insights into what may go awry in brains of people with Alzheimer’s
M ore than three decades of research on Alzheimer's disease have not produced any major treatment advances for those with the disorder, according to a UCLA expert who has studied the biochemistry of the brain and Alzheimer's for nearly 30 years. “Nothing has worked,” said Steven Clarke, a distinguished professor of chemistry and biochemistry.

Lab-based dark energy experiment narrows search options for elusive force
An experiment to test a popular theory of dark energy has found no evidence of new forces, placing strong constraints on related theories. Dark energy is the name given to an unknown force that is causing the universe to expand at an accelerating rate. It is very exciting to be able to discover something about the evolution of the universe using a table-top experiment in a London basement.

Hydrogen induces high-temperature superconductivity in a monolayer material
UAntwerp researchers from the CMT group, Dr Jonas Bekaert and Prof Milorad Milosevic, in collaboration with Swedish researchers have predicted that a atomically thin layer of hydrogen will boost the critical temperature of a thin superconductor to above a hundred kelvin. Hydrogen-rich bulk superconducting materials have recently exhibited record-breaking critical temperatures, nearing the ambient temperature and thereby promising a major technological impact on the society.

Scientists have demonstrated how chronic liver diseases cause molecular changes in the brain. They carried out their research using the 9.4 Tesla high-magnetic-field MRI machine at the Center for Biomedical Imaging (CIBM) at EPFL. The liver plays a vital role as a filter in the human body.

Very little was known till now about DNA repair by homologous recombination, which is fundamental for human health. Now an ETH research group has for the first time isolated and studied all the key proteins involved in this process, laying the foundation for investigating many diseases. Within our body, the process of cell division is constantly creating new cells to replace old or damaged ones.
Can animals sufficiently adapt to climate change?
A new study shows that in multiple animal species climate change causes changes in the life cycle, e.g. the timing of the egg hatching, or adaptations in their morphology, e.g. body size. GCE scientists Frank Adriaensen and Erik Matthysen have contributed to a newly published article in the interdisciplinary science.

Understanding ourselves and our past
Since the earliest civilizations, people have recorded their thoughts and experiences through storytelling, art, philosophy and other forms of expression. Studying these works - collectively known as the humanities - helps us understand the past and ultimately ourselves. Today's humanities scholars are rediscovering the past through traditional ways, such as reexamining an ancient mummy case with a fresh perspective, as well as more modern techniques, which include the use of big data analysis or 3-D and X-ray models.

Wearable sensors detect what’s in your sweat
New wearable sensors developed by scientists at UC Berkeley can provide real-time measurements of sweat rate and electrolytes and metabolites in sweat.

A team of scientists at the University of California, Berkeley, is developing wearable skin sensors that can detect what's in your sweat.

Atomically thin materials developed by Stanford researchers could create heat-shields for cell phones or laptops that would protect people and temperature-sensitive components and make future electronic gadgets even more compact. Excess heat given off by smartphones, laptops and other electronic devices can be annoying, but beyond that it contributes to malfunctions and, in extreme cases, can even cause lithium batteries to explode.
New research led by academics at the University of Bristol Veterinary and Medical Schools used the 'One Health' approach to study three bacterial species in the noses of young cattle and found the carriage of the bacteria was surprisingly different. The findings which combined ideas and methods from both animal and human health research could help prevent and control respiratory diseases.
Plants can tell the time, and this affects their responses to certain herbicides used in agriculture according to new research led by the University of Bristol. The study, in collaboration with Syngenta, found that plant circadian rhythms regulate the sensitivity of plants to a widely used herbicide according to the time of day.
Humans may have played a substantial role in the extinction of the European cave bear at the end of the last ice age. These findings of a study with the involvement of the University of Zurich suggest a drastic cave bear population decline starting around 40,000 years ago. Where in Europe did different populations of cave bears live and how they did they migrate during the Late Pleistocene? This is the topic that Verena Schünemann from the Institute of Evolutionary Medicine at the University of Zurich and a team of researchers investigated.
Relaxing of regulations for regenerative medicines has cascading effect internationally, new research warns
Countries that relax regulations for regenerative medicines could be causing a downward spiral in international standards, according to new research published today. Researchers warn that if just one country decides to relax regulations in the field, a heightened sense of competition can spur others to do the same.

Stanford engineers have developed experimental stickers that pick up physiological signals emanating from the skin, then wirelessly beam these health readings to a receiver clipped onto clothing. It's all part of a system called BodyNet. We tend to take our skin's protective function for granted, ignoring its other roles in signaling subtleties like a fluttering heart or a flush of embarrassment.
University of Queensland scientists have identified a way to help dermatologists determine a patient's risk of developing melanoma. UQ Diamantina Institute researcher Associate Professor Rick Sturm said the team uncovered the specific gene variations affecting the number and types of moles on the body and their role in causing skin cancer.
New insights into why a faulty gene involved in a devastating form of a kidney condition called nephrotic syndrome leads to disease in some patients have been identified in new Kidney Research UK-funded research led by the University of Bristol. The findings, published in the Journal of the American Society of Nephrology (JASN), could pave the way for new ways to prevent or treat the condition, by revealing new targets to intervene in the process.
#MeToo Media Coverage Sympathetic to but Not Necessarily Empowering for Women
The #MeToo movement has encouraged women to share their personal stories of sexual harassment. While the movement amplifies previously unheard voices, a Carnegie Mellon University analysis of #MeToo media coverage shows accusers are often portrayed as sympathetic, but with less power and agency than their alleged perpetrators.

The Earth's carbon cycle is crucial in controlling the greenhouse gas content of our atmosphere, and ultimately our climate. Ice sheets which cover about 10 percent of our Earth's land surface at present, were thought 20 years ago to be frozen wastelands, devoid of life and with supressed chemical weathering - irrelevant parts of the carbon cycle.
