A white dwarf living on the edge

Eurekalert - Jun 30 2021 - 00:06
The Zwicky Transient Facility has identified an extremely magnetized and rapidly rotating ultra-massive white dwarf. Several telescopes characterized the dead star, including two Hawai'i observatories -- W. M. Keck Observatory on Maunakea, Hawai'i Island and University of Hawai'i Institute for Astronomy's Pan-STARRS on Haleakala, Maui.

Study: Persistent socioeconomic, racial, and ethnic segregation in US safety-net hospitals

Eurekalert - Jun 30 2021 - 00:06
Results of a new study led by researchers at Boston Medical Center (BMC) show, however, that this expansion did not lead patients receiving care at safety-net hospitals to transfer their care to non-safety-net hospitals.

Targeted messaging for return to in-person visits

Eurekalert - Jun 30 2021 - 00:06
What The Study Did: Researchers in this randomized clinical trial found that a large proportion of patients who canceled visits and procedures early in the COVID-19 pandemic didn't reschedule once reopening occurred.

Effects of masks on exercise

Eurekalert - Jun 30 2021 - 00:06
What The Study Did: This crossover trial found that perceived breathing resistance at peak exercise is uniquely and significantly elevated when exercise stress testing (EST) is performed while wearing a mask. Performing EST with a mask yielded lower peak exercise oxygen uptake and heart rates as compared with no mask.

Investigational malaria vaccine gives strong, lasting protection

Eurekalert - Jun 30 2021 - 00:06
Two U.S. Phase 1 clinical trials of a novel candidate malaria vaccine have found that the regimen conferred unprecedentedly high levels of durable protection when volunteers were later exposed to disease-causing malaria parasites. The vaccine combines live parasites with either of two widely used antimalarial drugs -- an approach termed chemoprophylaxis vaccination. A Phase 2 clinical trial of the vaccine is now underway in Mali, a malaria-endemic country.

Abnormalities in how the brain reorganises prior experiences identified in schizophrenia

Eurekalert - Jun 30 2021 - 00:06
Neuroscientists at UCL have, for the first time, identified abnormalities in the way memories are 'replayed' in the brains of people with schizophrenia; researchers say the pathbreaking study provides an entirely new basis for explaining many of the condition's core symptoms.

Eating disorder behaviors alter reward response in the brain

Eurekalert - Jun 30 2021 - 00:06
A new NIMH-supported study found that eating disorder behaviors alter the brain's reward response process and food intake control circuitry, which can reinforce the behaviors.

Some brain disorders exhibit similar circuit malfunctions

Eurekalert - Jun 30 2021 - 00:06
MIT neuroscientists have uncovered a common neural mechanism for cognitive impairments seen in some people with autism and schizophrenia, even though the genetic variations that produce the impairments are different for each disorder.

Sanaria vaccine results show unprecedented progress in battle against variant malaria

Eurekalert - Jun 30 2021 - 00:06
In an article published today in Nature, Sanaria's PfSPZ-CVac (CQ) vaccine is reported as being safe and protecting 100% of six subjects against a variant malaria parasite three months after their last dose in the company's Phase 1 safety and efficacy trial. This is the first time complete protection against a variant malaria parasite has ever been achieved that long after vaccine administration.

Ecology: Deforestation threatens one of the world's largest eagles

Eurekalert - Jun 30 2021 - 00:06
Harpy eagles (Harpia harpyja) - which are among the world's largest eagle species - struggle to feed offspring in heavily deforested areas of the Amazon, according to a study published in Scientific Reports.

New beetle found in fossil feces attributed to dinosaur ancestor

Eurekalert - Jun 30 2021 - 00:06
The tiny beetle Triamyxa coprolithica is the first-ever insect to be described from fossil feces. The animal the researchers have to thank for the excellent preservation was probably the dinosaur ancestor Silesaurus opolensis, which 230 million years ago ingested the small beetle in large numbers.

Embryo freezing for IVF appears linked to blood pressure problems in pregnancy

Eurekalert - Jun 30 2021 - 00:06
A large cohort study drawn from the national IVF registry of France, which included almost 70,000 pregnancies delivered after 22 weeks gestation between 2013 and 2018, has found a higher risk of pre-eclampsia and hypertension in pregnancies derived from frozen-thawed embryos. This risk was found significantly greater in those treatments in which the uterus was prepared for implantation with hormone replacement therapies. The results confirm with real-life data what has been observed in sub-groups of patients in other studies.

Researchers look to human 'social sensors' to better predict elections and other trends

Eurekalert - Jun 30 2021 - 00:06
Researchers can gather highly accurate information about social trends and groups by asking about a person's social circle rather than interrogating their own individual beliefs.

During epic migrations, great snipes fly at surprising heights by day and lower by night

Eurekalert - Jun 30 2021 - 00:06
A stocky marsh bird with a 20-inch wingspan, great snipes are also speedy marathoners that can migrate from Sweden to Central Africa in just three days, without stopping to eat, drink, or sleep. Now, researchers find that snipes also rise nearly 2,500 meters in elevation at dawn and descend again at dusk each day, perhaps to avoid overheating from daytime solar radiation by climbing higher. The findings appear June 30 in the journal Current Biology.

New beetle species found pristinely preserved in fossilized dropping of dinosaur ancestor

Eurekalert - Jun 30 2021 - 00:06
Fossilized feces are common finds at paleontological dig sites and might actually contain hidden treasures. By scanning fossilized dung assigned to a close dinosaur relative from the Triassic period, scientists discovered a 230-million-year-old beetle species, representing a new family of beetles, previously unknown to science. The beetles were preserved in a 3D state with their legs and antennae fully intact. The finding appears June 30 in the journal Current Biology.
