A global science collaboration using data from NASA's Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station has discovered X-ray surges accompanying radio bursts from the pulsar in the Crab Nebula. The finding shows that these bursts, called giant radio pulses, release far more energy than previously suspected.
SALT LAKE CITY - A letter published today by Huntsman Cancer Institute (HCI) at the University of Utah (U of U) in the New England Journal of Medicine reports that melanoma mortality among Utahns outpaced that of the rest of the United States during the period from 1975 to 2013. Melanoma death rates have been decreasing in recent years both in Utah and the United States, a trend likely attributable to new, more effective treatments, like immunotherapy.
LOS ALAMOS, N.M., April 8, 2021-While attention has been focused on the Perseverance rover that landed on Mars last month, its predecessor Curiosity continues to explore the base of Mount Sharp on the red planet and is still making discoveries. Research published today in the journal Geology shows that Mars had drier and wetter eras before drying up completely about 3 billion years ago.
PHILADELPHIA (April 8, 2021) - Many factors, including need, affect healthcare use. Strategies geared to enhancing the provision and access to healthcare must consider the various mechanisms that contribute to healthcare need and use. Until now, the mechanism of violence and its impact on both health and healthcare use has not been investigated.
Ion channels play an indispensable role in cellular physiology, and understanding the physical features that affect ion channel functions is a matter of considerable interest to biologists. Given that mechanosensitivity is an intrinsic feature of cells, the complex set of mechanical stresses acting on a cell at any time represents an important consideration in the field of cellular physiology. In fact, stretching forces created by mechanical stress are sometimes necessary to activate ion channels.
BIRMINGHAM, Ala. - Six years ago, Michael Niederweis, Ph.D., described the first toxin ever found for the deadly pathogen Mycobacterium tuberculosis. This toxin, tuberculosis necrotizing toxin, or TNT, became the founding member of a novel class of previously unrecognized toxins present in more than 600 bacterial and fungal species, as determined by protein sequence similarity. The toxin is released as M. tuberculosis bacteria survive and grow inside their human macrophage host, killing the macrophage and allowing the escape and spread of the bacteria.
With the help of machine-learning techniques, a team of astronomers has discovered a dozen quasars that have been warped by a naturally occurring cosmic "lens" and split into four similar images. Quasars are extremely luminous cores of distant galaxies that are powered by supermassive black holes.
Cells from healthy individuals with major depressive disorder were found to have higher than expected rates of methylation at specific sites on their DNA, when compared to cells from healthy individuals without MDD, according to a study by a multidisciplinary team of Walter Reed Army Institute of Research and University of California San Francisco scientists, in collaboration with others.
New Haven, Conn. -- Alzheimer's disease is known for its slow attack on neurons crucial to memory and cognition. But why are these particular neurons in aging brains so susceptible to the disease's ravages, while others remain resilient?
WEST LAFAYETTE, Ind. - New insights into the immune response to SARS-CoV-2 infections could bring better treatments for COVID-19 cases.
An international team of researchers unexpectedly found that a biochemical pathway, known as the immune complement system, is triggered in lung cells by the virus, which might explain why the disease is so difficult to treat. The research is published this week in the journal Science Immunology.
When most Americans imagine an archaeologist, they picture someone who looks like Indiana Jones. Or, perhaps, Lara Croft, from the Tomb Raider game. White, usually male but occasionally female, digging up the spoils of a vanished culture in colonized lands.
Many Mario Kart enthusiasts are familiar with the rush of racing down Rainbow Road, barely squeaking around a corner, and catching a power-up from one of the floating square icons on the screen—or, less ideally, slipping on a banana peel laid by another racer and flying off the side of the road into oblivion. This heated competition between multiple players, who use a variety of game tokens and tools to speed ahead or thwart their competitors, is part of what makes the classic Nintendo racing game that has been around since the early 1990s so appealing.
A new clinical trial from King's College London's Institute of Psychiatry, Psychology, & Neuroscience, in collaboration with Oxford University, Oxford Health NHS Foundation Trust, Sussex University, and Sussex Partnership NHS Foundation Trust has established an innovative therapy as an effective means of treating paranoid thoughts in people experiencing psychosis.
CORVALLIS, Ore. - Eucalyptus, a pest-resistant evergreen valued for its hardy lumber and wellness-promoting oil, can be genetically modified not to reproduce sexually, a key step toward preventing the global tree plantation staple from invading native ecosystems.
Oregon State University's Steve Strauss led an international collaboration that showed the CRISPR Cas9 gene editing technique could be used with nearly 100% efficiency to knock out LEAFY, the master gene behind flower formation.
Two thirds of New Zealanders believed there were 'silver linings' to the country's Alert Level 4 COVID-19 lockdown imposed in March last year, a University of Otago survey has found.
The researchers were able to question New Zealanders while they were at home, giving a unique insight into their lives during the nationwide lockdown between 25 March and 23 April, widely regarded as one of the strictest imposed anywhere in the world.
One year on from lockdown, the results of their study have been published in the international scientific journal, PLOS ONE.
