Sweden’s Chalmers University of Technology has achieved a quantum computing efficiency breakthrough through a novel type of thermometer that is capable of simplifying and rapidly measuring temperatures during quantum calculations.
The discovery adds a more advanced benchmarking tool that will accelerate Chalmers’ work in quantum computing development.
The novel thermometer is the latest innovation to emerge from the university’s research to develop an advanced quantum computer. The so-called OpenSuperQ project at Chalmers is coordinated with technology research organisation the Wallenberg Centre for Quantum Technology (WACQT), which is the OpenSuperQ project’s main technology partner.
A research group from KTH has designed nano-sized particles, in an innovative way, to enhance the detection of tumors present inside the body and in biopsy tissue. The progress could allow early-stage tumors to be identified with lower doses of radiation.
Perceiving and handling deformable objects is an integral part of everyday life for humans. Automating tasks such as food handling, garment sorting, or assistive dressing requires open problems of modeling, perceiving, planning, and control to be solved. Recent advances in data-driven approaches, together with classical control and planning, can provide viable solutions to these open challenges. In addition, with the development of better simulation environments, we can generate and study scenarios that allow for benchmarking of various approaches and gain better understanding of what theoretical developments need to be made and how practical systems can be implemented and evaluated to provide flexible, scalable, and robust solutions. To this end, we survey more than 100 relevant studies in this area and use it as the basis to discuss open problems. We adopt a learning perspective to unify the discussion over analytical and data-driven approaches, addressing how to use and integrate mo

When it comes to distinguishing a healthy cell from an infected one that needs to be destroyed, the immune system s killer T cells sometimes make mistakes.
This discovery, described today in
eLife, upends a long-held belief among scientists that T cells were nearly perfect at discriminating friend from foe. The results may point to new ways to treat autoimmune diseases that cause the immune system to attack the body, or lead to improvements in cutting-edge cancer treatments.
It is widely believed that T cells can discriminate perfectly between infected cells and healthy ones based on how tightly they are able to bind to molecules called antigens on the surface of each. They bind tightly to antigens derived from viruses or bacteria, but less tightly to our own antigens on normal cells. But recent studies by scientists looking at autoimmune diseases suggest that T cells can attack otherwise normal cells if they express unusually large numbers of our own antigens, even tho

A rare mutation that causes Parkinson s disease-like symptoms interrupts the flow of dopamine in the brain, suggests a study in fruit flies published today in
eLife.
The findings provide more detailed insights about why young children with this mutation develop these symptoms. This new information, as well as previous evidence that therapies helping to improve dopamine balance in the brain can alleviate some symptoms in the flies, suggests that this could be a beneficial new treatment strategy.
Parkinson s disease causes progressive degeneration of the brain that leads to impaired movement and coordination. Current treatments focus on replacing or increasing the levels of dopamine to help reduce movement-related symptoms. But these drugs can have side effects, do not resolve all symptoms, and often stop working over time.
