A researcher from RUDN University suggested that Xanthomonas bacteria that are harmful to plants might have developed from a nonpathogenic related species by receiving virulence genes from other species of bacteria.

Allowing for quantum corrections, the Einstein-Lovelock theory describes black holes with an equation that contains an infinite number of terms. However, according to a RUDN University physicist, the geometry of a black hole in this theory can be presented in a compact form, and a limited number of terms can suffice to describe the observed values. This could help scientists study black holes in...

Researchers studied clinical practice patterns in non-physician members of Army FRSTs, particularly comparing the experience of active duty and Army reservist team members.

Currently, aggregation induced emission luminogens (AIEgens) materials reveal excellent performance in bioimaging. However, the current AIEgens suffer from poor targeting selectivity due to undesirable aggregation in hydrophilic biosystem with "always-on" fluorescence or unspecific aggregation in lipophilic organelle with premature activated fluorescence. Wei-Hong Zhu's group from the East China...

Brain-Computer Interfaces (BCIs), which aim to construct a pathway for people to interact with computers directly by thought, have received great attention in recent years. An electroencephalogram-based BCI speller, which allows the user to input text to computer using brain signals, is one of the most popular BCI systems. However, researchers in China show that these BCI spellers can be easily...

When it comes to surgery, minority children lag far behind white children, according to two analyses of large national databases being presented at the ANESTHESIOLOGY® 2020 annual meeting.

Universal COVID-19 testing of children who are having procedures requiring anesthesia promotes efficient use of personal protective equipment (PPE), according to research being presented at the ANESTHESIOLOGY® 2020 annual meeting.

Limited English-language proficiency (LEP) is a risk factor for getting potentially lifesaving screening mammograms less often.

Researchers describe a newly observed phenomenon in the way blood pressure is maintained in certain rats.

A new paper in the journal Science Advances describes the discovery of several promising small molecules that appear to reduce cellular stress in mouse skin cells and could lengthen life.

Among accredited U.S. cancer centers, hospitals serving primarily minority patients are as likely as other hospitals to offer the standard of surgical care for early-stage breast cancer.

Efficient and stable blue OLED is still a challenge due to the lack of emitter simultaneously with high efficiency and short excited-state lifetime. A blue emission cerium(III) complex was demonstrated for a high efficiency OLEDs with superior stability. The excellent performance could be assigned to the nanoseconds spin- and parity- allowed 5d?4f transition of Ce3+ ion. Along with adjustable...

New applications of artificial intelligence (AI) in health care settings have shown early success in improving survival and outcomes in traffic accident victims transported by ambulance and in predicting survival after liver transplantation.

Pregnant women who underwent immediate surgery to treat a ruptured or abscessed appendix and their fetuses had significantly better outcomes than those whose condition was managed without an operation.

A beta test of a program for older adults who undergo major surgery has resulted in shorter hospital stays and lower rates of post-surgery delirium, among other improved outcomes.

Researchers have identified genetic mutations that appear to protect women from severe bleeding after childbirth, a leading cause of maternal death. A preliminary study of the findings is being presented at the ANESTHESIOLOGY® 2020 annual meeting.

Almost 20 years into the opioid epidemic, there finally is evidence of significant and continual decreases in the abuse of these risky pain medications, according to an analysis of national data being presented at the ANESTHESIOLOGY® 2020 annual meeting.

Two studies presented at the American College of Surgeons (ACS) Clinical Congress 2020 provide evidence that STOP THE BLEED® training is effective and has made a lifesaving difference around the world.

Opioid guidelines may be missing a small group of patients that need a greater level of pain control.

Young women with benign breast conditions may undergo surgery without jeopardizing their ability to breastfeed later on.

Transportation barriers, such as personal access to a vehicle or public transportation, disproportionally affect minority communities.

A major study of women with DCIS - a breast condition that can become invasive cancer - has shown that surgery to remove the tissue followed by radiotherapy offers better protection compared to surgery alone. The study, presented at the 12th European Breast Cancer Conference, followed patients for up to 27 years. Although it shows that the benefit of radiotherapy and surgery over surgery alone...

Scientists from China and America demonstrate broadband two-dimensional spatial differentiation and high-contrast edge imaging based on a dielectric metasurface. The edge detection method works for both intensity and phase objects simply by inserting the metasurface into a commercial optical microscope. This highly efficient metasurface performing a basic optical differentiation operation opens...
