Cities are vibrant centers of modern life, tied together by dense and diverse networks of socioeconomic interactions. But the sorts of connections that foster creativity and innovation in cities now threaten to spread the novel coronavirus.

Astronomers have used the National Science Foundation's Karl G. Jansky Very Large Array (VLA) and NASA's Spitzer Space Telescope to make the first measurement of wind speed on a brown dwarf -- an object intermediate in mass between a planet and a star.
Based on facts known about the giant planets Jupiter and Saturn in our own Solar System, a team of scientists led by Katelyn Allers of Bucknell University realized that they possibly could measure a brown dwarf's wind speed by combining radio observations from the VLA and infrared observations from Spitzer.
Four fossilized monkey teeth discovered deep in the Peruvian Amazon provide new evidence that more than one group of ancient primates journeyed across the Atlantic Ocean from Africa, according to new USC research just published in the journal Science.
WASHINGTON, DC--An article published in Science magazine finds deep flaws in the US Environmental Protection Agency (EPA)'s benefit-cost analysis in support of a proposed rule related to the regulation of hazardous air pollution from coal-burning power plants. The analysis forms part of the foundation for a regulatory proposal to roll back the legal underpinnings of its Mercury and Air Toxics Standards (MATS), which power plants have been complying with since 2016, leaving the standards vulnerable to legal challenges.
Using immunotherapy immediately after chemotherapy treatment in patients with metastatic bladder cancer significantly slowed the progression of the cancer, according to results of a clinical trial led by Mount Sinai researchers published in the Journal of Clinical Oncology in April.
The study is the first to show that this approach to therapy, called switch maintenance immunotherapy, significantly slows the worsening of a type of bladder cancer called urothelial cancer. The randomized Phase 2 trial tested this treatment in 108 patients.
NEW YORK -- Every moment of the day we are surrounded by smells. Odors can bring back memories, or quickly warn us that food has gone bad. But how does our brain identify so many different odors? And how easily can we untangle the ingredients of a mixture of odors? In a new study in mice published today in Science, Columbia scientists have taken an important step toward answering these questions, and the secret lies inside the nose.
The Journal of Clinical Oncology reports that a subgroup of women on chemotherapy in the landmark TAILORx breast cancer treatment trial had an early and abrupt cognitive decline at three and six months following treatment, which leveled off at 12 and 36 months. The women received chemotherapy plus hormone therapy following surgery, to prevent the disease from returning. The publication also reports the loss of cognition in women who received hormone therapy alone.
Perhaps the most important lesson we can learn from the current coronavirus pandemic is how to learn future lessons without having to experience a pandemic, whether natural in origin or made by humans. To do so, we need to change how we think about the governance of biology.
In a Policy Forum article in this week's issue of Science, lead author Dr. Sam Weiss Evans, a Fellow at Harvard Kennedy School's Program on Science, Technology and Society, joins more than a dozen stakeholders in calling for a new approach to biosecurity governance, grounded in experimentation.
ROCHESTER, Minn. -- Much remains unknown about COVID-19, but many studies already have indicated that people with cardiovascular disease are at greater risk of COVID-19. There also have been reports of ST-segment elevation (STE), a signal of obstructive coronary artery disease, in patients with COVID-19 who after invasive coronary angiography show no sign of the disease.
ROCHESTER, Minn. -- As COVID-19 testing becomes more widely available, it's vital that health care providers and public health officials understand its limits and the impact false results can have on efforts to curb the pandemic.
CHAMPAIGN, Ill. -- A multidisciplinary team of researchers at the University of Illinois at Urbana-Champaign has developed tiny sensors that measure oxygen transport in bovine lung tissue. The study - which establishes a new framework for observing the elusive connection between lung membranes, oxygen flow and related disease - is published in the journal Nature Communications.
Philadelphia, April 9, 2020 - Researchers at Children's Hospital of Philadelphia (CHOP) have pinpointed a genetic variation responsible for driving the development of inflammatory bowel disease (IBD). The genetic pathway associated with this variation is involved in other immune disorders, suggesting the mechanism they identified could serve as an important therapeutic target. The findings were published today by the Journal of Crohn's and Colitis.
In the course of every single cell division, the genetic information on the chromosomes must be distributed equally between the newly developing daughter cells. The enzyme separase plays a decisive role in this process. Susanne Hellmuth and Olaf Stemmann from the Chair of genetics at the University of Bayreuth have now discovered a previously unknown mechanism that regulates the activity of the separase. These fundamental findings add a new aspect to our current understanding of chromosome inheritance. The scientists have presented their study in the journal "Nature".
New Rochelle, NY, April 9, 2020--The new, global Traditional, Complementary and Integrative Health and Medicine (TCIHM) COVID-19 Support Registry aims to capture key information on the case, treatment/supportive care, and outcome variables related to the use of integrative health products and practices in patients in response to the COVID-19 pandemic.
BUFFALO, N.Y. - While researchers have suggested that individuals who base their self-worth on their financial success often feel lonely in everyday life, a newly published study by the University at Buffalo and Harvard Business School has taken initial steps to better understand why this link exists.
"When people base their self-worth on financial success, they experience feelings of pressure and a lack of autonomy, which are associated with negative social outcomes," says Lora Park, an associate professor of psychology at UB and one of the paper's co-authors.
