Of the more than 200,000 women in U.S. federal and state prisons and jails, it is estimated that up to 10% are pregnant and will give birth while incarcerated. Clinical practice guidelines to support breastfeeding and increase infants’ access to human milk are well established. However, little data assess the extent to which they are modifiable or applicable for incarcerated mothers.
Replenishing the body’s high-density lipoprotein (HDL) could be an effective treatment for sepsis, according to a new University of Kentucky College of Medicine study published in Science Signaling. The lab study, led by Xiangan Li, Ph.D., a professor in the Department of Physiology and the Saha Cardiovascular Research Center, found that a synthetic form of HDL provided protection against sepsis in mice.
The question of how gender shapes academic performance has been a subject of study for several decades, revealing “the rise of women” in education and defining a “new gender gap” in education that primarily refers to boys’ academic underperformance. But in documenting these patterns, scholars have largely ignored one critical axis of inequality: Sexuality.
Coral reefs in the Gulf of Eilat (also known as the Gulf of Aqaba) have been proven particularly resistant to global warming, rising water temperatures and bleaching events that are crippling their counterparts elsewhere around the world.

New research from Mayo Clinic's Center for Individualized Medicine finds that patients with ASXL1-mutant chronic myelomonocytic leukemia — an uncommon type of cancer of the bone marrow — have distinctive epigenetic changes that can activate harmful genes and cause the cancer to grow faster. The ASXL1 genetic mutation also can transform the disease into the more aggressive acute myeloid leukemia.
The study provides scope and context to departures of public health officials during the first phase of the pandemic.

Men in executive leadership positions receive over $500,000 more in severance compensation than women, according to researchers from the University of New Hampshire and the University of Nebraska at Omaha. Researchers say a gender pay gap exists in average severance compensation packages between male and female executives in large, publicly traded American companies.

Wellinks®, a digital health care company offering the first-ever integrated, virtual Chronic Obstructive Pulmonary Disease (COPD) management solution, today announced results from a study that found that older adults with COPD were highly engaged and satisfied with Wellinks.
Irvine, Calif., March 17, 2022 – An international team of researchers has demonstrated a novel approach to bipedal robotic locomotion using birds as inspiration. While many robots utilize human-inspired mechanisms for bipedal locomotion, the bipedal locomotion of birds — with a track record going back hundreds of millions of years by way of evolving from dinosaurs — might prove to be a better, more effective form of locomotion for robotics.
Analyzing more than 200 years of conflicts, David Carter at Washington University in St. Louis finds revisionist states — like Russia — have made territorial claims when the great powers that dominate the international system are embroiled in crisis.
Researchers from the UAB, IFAE and University College London propose using the variations in distance between the Earth and the Moon, which can be measured with a precision of less than a centimeter, as a new gravitational wave detector within a frequency range that current devices cannot detect.
Runoff in coastal waters is linked to pollution and degradation of coral reefs and other marine ecosystems.

A study of more than eight million people published by The BMJ today finds no increased risk of rare neurological events after covid-19 vaccination.
The team's latest study, published in Cell, shows that two clever human antibodies can target two ebolavirus species at once: Ebola virus and Sudan virus. These two species are responsible for the biggest, deadliest outbreaks. The new report suggests researchers could combine these two potent antibodies to make a powerful antiviral therapy.
Columbia Engineering researchers report that they have developed a “cloaking” system that temporarily hides therapeutic bacteria from immune systems, enabling them to more effectively deliver drugs to tumors and kill cancer cells in mice. By manipulating the microbes’ DNA, they programmed gene circuits that control the bacteria surface, building a molecular “cloak'' that encapsulates the bacteria.
Scientists at Yale Cancer Center have discovered new consequences of specific gene mutations that play a role in the development of myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML).
A group of Russian and Ukrainian cyber-hackers were clearly risk-takers. But their actions after stealing embargoed news releases for publicly-traded companies shows trades based on the lifted information were far from reckless, new research shows.

Researchers at the University of Illinois Chicago are looking at the possibility that gastroenterological changes could be an early warning sign for Lou Gehrig's disease. Their research in animal models also shows a promising treatment to slow the disease’s progression.
For optimal performance, thermoelectric materials must conduct small amounts of heat and large amounts of electricity. However, crystal structure and electrons that carry electricity also carry heat. Researchers have found that doping black phosphorous with arsenic results in a 2-D material with a structure that may break the link between heat and electrical conductivity, resulting in improved thermoelectric power and potential for use in future energy-efficient technologies.
Mayo Clinic researchers have identified a new set of molecular markers in blood plasma. This discovery could lead to the development of improved diagnostic tests for Alzheimer's disease. Alzheimer's disease is the most common form of dementia, affecting 6.2 million people in the U.S. The Mayo Clinic study, published in eBioMedicine, is the first study to focus on RNA molecules in plasma as biomarkers for Alzheimer's disease in African Americans — the population at greatest risk for developing Alzheimer's disease. This approach enabled researchers to pinpoint specific molecules in plasma that could serve as biomarkers to confirm a diagnosis of Alzheimer's disease in this population.
