New research by University of Wisconsin-Madison Professor of Pharmacy Seungpyo Hong and his collaborators builds on several years of work in isolating circulating tumor cells, or CTCs, by demonstrating improved methods for their capture on clinical samples for the first time.
Nearly half of adolescents aren’t receiving a pair of vaccines to prevent a virus many of them will get.
Chemical compounds carry distinctive absorption “fingerprints,” within the mid-infrared spectral region; this offers an opportunity to measure and study chemicals at extremely sensitive levels, but researchers currently lack the tools required. In a breakthrough, NIST researchers developed an on-silicon-chip laser source with outputs that consist of precisely defined and equally spaced optical lines within the mid-infrared spectral region. They report their findings in APL Photonics.
UCLA scientists have developed a new method that utilizes microscopic splinter-like structures called “nanospears” for the targeted delivery of biomolecules such as genes straight to patient cells. These magnetically guided nanostructures could enable gene therapies that are safer, faster and more cost-effective.

Supercomputer simulations predict how E. coli adapts to environmental stresses.
Spin caloritronics explores how heat currents transport electron spin, and researchers are particularly interested in how waste heat could be used to power next-generation spintronic devices. The thermally driven transport application of spin caloritronics is based on the Seebeck effect; researchers in China have theoretically exposed the fundamental aspects of this thermal transport along double-stranded DNA molecules. They reported their findings in the Journal of Applied Physics.
A Ludwig Cancer Research study shows that ovarian cancer, which has proved resistant to currently available immunotherapies, could be susceptible to personalized immunotherapy. Led by Ludwig Lausanne investigator Alexandre Harari and George Coukos, director of the Ludwig Institute for Cancer Research, Lausanne, the study shows that ovarian tumors harbor highly reactive killer T cells—which kill infected and cancerous cells—and demonstrates how they can be identified and selectively grown for use in personalized, cell-based immunotherapies.

项新的Mayo Clinic研究表明，高达97％的患者能够从容面对医疗服务者提出的关于性取向和性别认同的问题。 在这项研究之前，人们不清楚，这些研究人员认为对于减少LGBTI(同性恋，双姓恋，变性者及双性者)患者之间的健康差异非常重要的问题是否会冒犯患者。 这些发现今天发表在《卫生服务研究》杂志上（Health Services Research）。
Individuals with lower-pitched voices are more likely to win elected office because they are believed to be superior leaders. But is voice pitch a reliable signal of leadership quality? And is the bias in favor of selecting leaders with lower voices good or bad for democracy? A novel study is the first to address these questions.
Bioreactors, which are woodchip-filled ditches and trenches, are often used near crop fields to filter the water running off of them. The woodchips enhance a natural process called denitrification that prevents too much nitrogen from getting into other bodies of water like rivers and streams.
In a study conducted in rural India, Johns Hopkins Medicine researchers working in collaboration with Bal Umang Drishya Sanstha (BUDS), a nonprofit Indian organization focused on child health, have found that mobile phone reminders linked with incentives such as free talk time minutes work better than phone alerts alone to improve childhood immunization rates in poor communities.
Researchers at University of California San Diego School of Medicine have developed a microbial detection technique so sensitive that it allows them to detect as few as 50-100 bacterial cells present on a surface. What’s more, they can test samples more efficiently — up to hundreds of samples in a single day.
African Americans with a common genetic variation are at increased risk for developing Alzheimer’s disease, while European Americans with the same variation are not, according to a study led by researchers at Rush University Medical Center.

As ocean temperatures rise and oceanic diseases proliferate, species like sea stars struggle to survive, and scientists are looking for underlying causes. To bring clarity to the sea star disease problem, the scientists propose a new, broad nomenclature in a study published in Frontiers in Marine Science.
When teaching identical online courses, a woman receives harsher comments and lower scores than a man.
Nearly all school nurses participating in a national survey (96 percent) reported that staff at their school received training on handling severe allergic reactions to food. Over 80 percent asserted that their school had an emergency epinephrine auto-injector on hand to stop a potentially life-threatening allergic reaction. The study findings, published in the Annals of Allergy, Asthma and Immunology, also underscore the dire need for these policies, with over one-third of the school nurses reporting at least one severe allergic reaction to food at their school in the last academic year.
New research from Huntsman Cancer Institute (HCI) at the University of Utah (U of U) indicates steroid and hormone receptors are simultaneously active in many endometrial cancer tissues. The findings, published today in the journal Cell Reports, yield insights about factors that contribute to more aggressive endometrial tumors.
A new paper by Northern Arizona University professor Andrew Richardson published in the journal Scientific Data describes a vast network of digital cameras designed to capture millions of images documenting seasonal changes of vegetation across North America.
"Has this patient been drinking?" It's a critical question for neurosurgical nurses and other professionals when evaluating patients with traumatic brain injury (TBI). But some groups of TBI patients are less likely to be screened for alcohol use, including women and younger patients, reports a study in the March issue of the Journal of Neuroscience Nursing, official journal of the American Association of Neuroscience Nurses.
Bioreactors are used to produce different therapeutics in the biopharmaceutical and regenerative medicine industries. Drug development relies on small multi-well plates shaken around an orbital diameter, while production-scale bioreactors are agitated by stirring. These different methods yield different fluid dynamics. Researchers in the U.K. are starting to bridge this gap by applying analytical techniques for stirred bioreactors to the fluid dynamics of orbitally shaken bioreactors. They discuss their work in this week’s Physics of Fluids.

High drug prices as well as the excessive use of imaging and surgical procedures, and excessive administrative burdens contribute the majority to America’s health care overspending compared to Europe, argues policy expert Ezekiel J. Emanuel, MD, PhD, chair of the department of Medical Ethics and Health Policy at the Perelman School of Medicine at the University of Pennsylvania, in an editorial in this week’s JAMA.
