New study uses live imaging to understand a critical step in early embryonic development--how genes and molecules control forces to orchestrate the emergence of form in the developing embryo. The study findings could have important implications for how stem cells are used to create functional organs in the lab, and lead to a better understanding of the underlying causes of gastrointestinal birth defects.

Scientists have managed to grow perfect human blood vessels as organoids in a petri dish for the first time. The breakthrough engineering technology, outlined in a new study published today in Nature, dramatically advances research of vascular diseases like diabetes, identifying a key pathway to potentially prevent changes to blood vessels--a major cause of death and morbidity among those with diabetes.

An international team of researchers, including the University of Leicester, found evidence for the much theorized 'hot cocoon'.

Scientists have traditionally thought that DNA binding proteins use patterns in the genome's code of As, Cs, Ts, and Gs to guide them to the right location, with a given protein only binding to a specific sequence of letters. In a new study, published in Cell Systems, scientists at the Gladstone Institutes discovered that proteins must rely on another clue to know where to bind: the DNA's three-dimensional shape.

Breast cancers diagnosed in young women within 10 years of giving birth are more likely to metastasize, and thus more likely to cause death, than breast cancers in young women who gave birth less recently or not at all.

Fewer than half of young people in the United States are having discussions of sensitive topics with their regular healthcare providers, according to a new study published in Pediatrics. This new research led by researchers at the Columbia Mailman School of Public Health suggests that modifying healthcare delivery practices may improve discussions between youth and their healthcare providers. Youth-provider discussions are important opportunities to promote health for young people.

A new Northwestern Medicine study was able to successfully predict -- with 72.8 percent accuracy -- if a new mother would experience worsening depressive symptoms over the first year after giving birth. The scientists predicted this depression trajectory using four maternal characteristics that put the mother at risk. Identifying these factors early in the postpartum period will allow mothers to seek treatment earlier and improve their chance of a full recovery.

A new study finds acupressure could be a low-cost, at-home solution to a suite of persistent side effects that linger after breast cancer treatment ends.

(Springer) In the late 1950s, the treatment for fractures involved three to four months in hospital in plaster-casts and traction. Recovery was slow, and up to 70 percent of patients experienced reduced mobility upon recovery.

(University of Utah) The W. M. Keck Foundation has awarded $250,000 to the University of Utah to establish a new undergraduate minor in dark sky studies, the first of its kind in the United States. The minor is open to all students across the university who will explore issues through the lens of science, humanities, arts, and participate in field-based research.

An image from the international Cassini spacecraft provides evidence of rainfall on the north pole of Titan, the largest of Saturn's moons. The rainfall would be the first indication of the start of a summer season in the moon's northern hemisphere.

Sudden bursts of heat that can damage the inner walls of tokamak fusion experiments are a hurdle that operators of the facilities must overcome. Such bursts, called 'edge localized modes (ELMs),' occur in doughnut-shaped tokamak devices that house the hot, charged plasma that is used to replicate on Earth the power that drives the sun and other stars. Now researchers at the US Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have directly observed a possible and previously unknown process that can trigger damaging ELMs.

Nepal was struck by an earthquake with a magnitude of 7.8 in 2015, but the country may still face the threat of much stronger temblor. This is the conclusion reached by ETH researchers based on a new model that simulates physical processes of earthquake rupture between the Eurasian and Indian Plates.

New research, led by the University of Leicester, will optimise the welding and additive and manufacturing process

The "First international consensus on the diagnosis and management of fibromuscular dysplasia" (FMD) has been published online first today in Vascular Medicine and the Journal of Hypertension.

A new Tel Aviv University study suggests that the role of yeast, the world's most basic eukaryotic unicellular organism, may pave the way for the development of novel, more effective therapies for congenital diseases.

A team of scientists has, for the first time, used a single, cohesive computer model to simulate the entire life cycle of a solar flare: from the buildup of energy thousands of kilometers below the solar surface, to the emergence of tangled magnetic field lines, to the explosive release of energy in a brilliant flash.

By combining deep learning algorithms and statistical methods, investigators from the Institute of Evolutionary Biology (IBE), the Centro Nacional de Análisis Genómico (CNAG-CRG) of the Centre for Genomic Regulation (CRG) and the Genomics Institute at the University of Tartu have identified, in the genome of Asiatic individuals, the footprint of a new hominid who cross bred with its ancestors tens of thousands of years ago.

Research shows that drones can be more effective and safer in crash mapping of vehicular highway accidents than conventional methods. Drones using new imaging technology developed at Purdue University allows highway safety officers to capture and print 3D composites of crash sites and reduce mapping time and improve traffic flow following a crash by 60 percent.

A mechanism which drives leukaemia cell growth has been discovered by researchers at the University of Sussex, who believe their findings could help to inform new strategies when it comes to treating the cancer.

The multi-year university research project is tracking tagged hummingbirds as they approach RFID-enabled feeders, in order to better understand visitation patterns and the potential for disease transmission.

OTTAWA — Prime Minister Justin Trudeau told a crowd in St. Catharines Tuesday that he was a tad naive after his election win, thinking his party's pledge to "stay positive and not use negative attack ads" may have changed politics.

(Wildlife Conservation Society) A new WCS-led study published in the journal Biological Conservation says the future of tigers in Asia is linked the path of demographic transition -- for humans.

(Université libre de Bruxelles) The new European collaborative project SCREENED aims to develop three-dimensional (3D) cell-based in vitro tests to better characterize the effects of endocrine disruptors on thyroid functions. This method will overcome the limitations of existing tests, being more sensitive, at low doses of exposure to chemicals, and enabling the prediction of their toxicity on human health in a sex-specific manner.

(Virginia Tech) "Our research is especially important because it goes beyond general possibilities to the more specific ones," Reddy said.
