Tech Xplore / Electric 'nose' can smell when your food's gone bad
Most of us have used the sniff test to decide whether a slightly expired bottle of milk or a week-old box of takeout is still good to eat. But while the human nose can be quite astute, it doesn't always catch everything. ...
Phys.org / Drivers of academic misconduct by professors and research students revealed
Ensuring the research that we all rely on—whether for our health, environment or economy—is trustworthy is important for universities, governments and business. Unfortunately, academic misconduct is a growing concern, with ...
Phys.org / Radar echoes from Europa reveal secrets beneath the ice
A team of scientists has used NASA's Goldstone Solar System Radar and the U.S. National Science Foundation Green Bank Telescope (NSF GBT) to carry out the most extensive radar study to date of Europa, the ocean world orbiting ...
Medical Xpress / Seven years after Ebola, survivors still live with neurological scars left by the disease
Ebola virus disease is caused by infection with an orthobolavirus found primarily in sub-Saharan Africa and can be fatal in 50% of those infected, on average. Among those who survive the disease, it leaves behind its imprint ...
Phys.org / Superconducting TES array X-ray spectrometer goes into operation at BESSY II
Europe's first and only TES spectrometer at a synchrotron source is now in operation at BESSY II, developed within a collaboration between the HZB, the MPI-CEC (Mühlheim-an-der-Ruhr, Germany) and the NIST (Boulder, Colorado, ...
Phys.org / From prejudice to harm—current policies targeting trans people follow a clear pattern of escalation
Public debates about transgender issues are often framed as disagreements over evidence or safety. In my new article published in the International Journal of Transgender Health, I argue current policy shifts are better understood ...
Medical Xpress / Cuddling cats might make us feel worse when under stress
Researchers just got one step closer to solving the age-old question of whether cats or dogs make better pets. A team in the Netherlands set out to better understand the nuances and underlying mechanisms behind the positive ...
Tech Xplore / Floating solar panels keep working through icy Canadian winters
To accommodate the increasing demand for clean energy, researchers have been developing floating solar panels for rivers, reservoirs and other waterways in recent years. While there is, of course, plenty of land for solar ...
Phys.org / LOFAR reveals spike-like repeating radio burst pairs in the solar corona
The solar atmosphere is a turbulent and magnetized environment, with the release of magnetic energy readily manifesting as emission across the electromagnetic spectrum. Solar radio emission dominates the radio sky, with the ...
Phys.org / Dark matter cannot be ruled out as cause of gamma ray glow at the Milky Way's center, machine learning shows
An international research collaboration between the University of Vienna and Lawrence Berkeley National Laboratory in the United States has used machine learning to re-examine one of the most debated signals in astrophysics. ...
Phys.org / 'Double the damage': Warming climate reduces milk quality and quantity
Heat stress on dairy cows affects more than just the quantity of milk produced—warming temperatures also reduce the fat and protein content of the milk, new research finds.
Phys.org / Northern permafrost switches from carbon sink to carbon source earlier than thought in models including deep soil carbon
The Arctic and northern high latitudes are warming about 2–4 times faster than the global average, allowing ancient permafrost to thaw and release stored carbon. These permafrost soils currently store roughly one-third of ...
