Scientists have for the first time detected black holes eating neutron stars, "like Pac Man", in a discovery documenting the collision of the two most extreme and enigmatic objects in the Universe.

Heart attacks during the COVID-19 pandemic were more likely to result in heart failure compared with heart attacks one year earlier, according to research presented today at Heart Failure 2021, an online scientific congress of the European Society of Cardiology (ESC). 'Heart attack patients waited an average of 14 hours to get help during the pandemic, with some delaying for nearly two days. That compares to a delay of six hours in the previous year.'

Researchers from Queen Mary University of London have identified a protein that could be used to aid in the diagnosis of pancreatic cancer.

Studies indicate that the optimal and safe number of oocytes needed for achieving an ongoing pregnancy is between six and 15. A retrospective observational study suggests that IVF clinics in the UK may be retrieving "far too many oocytes" and that most of them "may never be used and are probably discarded".

Some neuroscience theories suggest the human brain operates best 'at the edge of chaos'. Now scientists in Australia and Japan have found that keeping a nanowire network at the edge of becoming chaotic is the best state for it to produce useful signals to solve problems.

New biomarkers that predict HIV remission after antiretroviral therapy (ART) interruption are critical for the development of new therapeutic strategies that can achieve infection control without ART, a condition defined as functional cure. Wistar scientists have identified metabolic and glycomic signatures in the blood of a rare population of HIV-infected individuals who can naturally sustain viral suppression after ART cessation, known as post-treatment controllers.

Fertility patients who have a poor response to ovarian stimulation represent a stubborn challenge in IVF. Clinical guidelines indicate that increasing the drug dose for stimulation or applying any of several adjunct therapies are of little benefit. A study assessing two cycles of ovarian stimulation and two egg collections in the same menstrual cycle may yet provide a real advance for predicted poor responders in IVF.

After centuries of human impact on the world's ecosystems, a new study from Flinders University details an example of how a common native bee species has flourished since the very first land clearances by humans on Fiji. In a new paper in Molecular Ecology, research led by Flinders University explores a link between the expansion of Homalictus fijiensis, a common bee, which has increased its spread on the main island Viti Levu alongside advancing land clearance and the introduction of new plants and weeds.

In a paper published by Research Involvement and Engagement, the University of Surrey and its partners highlight the importance and value of 'lived experience' that only people in prison can provide to shape meaningful research and policy decisions.

Immunologists at McMaster University have discovered a previously unknown mechanism which acts like a spider web, trapping and killing pathogens such as influenza or SARS-CoV-2, the virus responsible for COVID-19.

New advances in stem cell research will help scientists battle diseases, develop drugs and, eventually, grow organs for transplant.

Government and public health experts in India have tried to convince poor households to shift to 'clean cooking' technology to reduce the use of wood, charcoal, and other traditional fuels. But in a country where household air pollution claims 600,000 lives per year, the shift has been slow. A new study led by Boston College researchers finds that personal networks play a significant role in whether rural poor households adopt cleaner fuels.

CORVALLIS, Ore. - Research by a graduate student in Oregon State University's College of Science has upended the conventional wisdom that for a century has incorrectly guided the study of a toad listed as endangered in part of its range.

A research team in Korea Institute of Civil Engineering and Building Technology (KICT) has developed co-axial electrospun nanofiber membranes fabricated by an alternative nanotechnology, which is electrospinning. This new desalination technology shows it has the potential to help solve the world's freshwater shortage. The developed technology can prevent wetting issues and also improve the long-term stability in membrane distillation process.

A new paper in JNCI Cancer Spectrum indicates that many survivors of adolescent and young adult cancers hesitate to obtain COVID-19 vaccinations.

Black men most likely to benefit from advanced prostate cancer therapies are 11% less likely to get them than non-Black men.

California's old-growth blue oak woodlands are dying off, shows a new study by the open access publisher Frontiers. The authors use a new approach to show that heat, drought and wildfires are the all contributing to the loss and deterioration of these native ecosystems. The study focuses on the extreme drought of 2012-2016, but suggests that these conditions will become more frequent in the future.

In the midst of the COVID-19 pandemic, infection preventionists at two Southern California hospitals took extreme measures to stop the spread of a deadly fungus that has emerged in the U.S. and around the world. The two will detail their proactive responses in oral presentations today at the Association for Professionals in Infection Control and Epidemiology's (APIC's), 48th Annual Conference.

A microfilter device that can easily separate and capture trace amounts of cancer cells in blood has been developed by a Kumamoto University research group. The palm-sized device is expected to contribute to the development of new cancer diagnostic technologies based on cancer cells in the blood, such as early detection by blood test, postoperative management, and recurrence monitoring.

A team of scientists from Nanyang Technological University, Singapore (NTU Singapore) has developed a test kit for malaria that delivers results in 30 minutes. The kit could facilitate the diagnosis of malaria in the field, as the equipment needed is anticipated to be lightweight, easy-to-use, and able to detect the disease in its early stages.
