Conditions in Arctic waters are among the most extreme in the world. Strong winds and currents powerfully push ice across vast distances, resulting in large ridges reaching tens of metres in height. At the same time, global warming and increased human presence have added new pressures in these northern environments. Yet the mechanisms behind the effects of ice on physical structures -- particularly over the long term -- have remained an open question in a time of continuous environmental change.

CHAMPAIGN, Ill. -- As foxes and coyotes adapt to urban landscapes, the potential for encounters with humans necessarily goes up. A team of scientists is taking advantage of this fact to enlist the eyeballs and fingertips of humans - getting them to report online what they see in their own neighborhoods and parks.

One goal of the research, reported in the journal Landscape and Urban Planning, is to determine how information gathered by "citizen scientists" stacks up against data more laboriously collected by researchers who study canids like foxes and coyotes.

Chemical analyses of meteorites allow for a better estimation of the chemical composition of the Earth and its potential building blocks. That is the result of a study conducted by a research team from the Institutes of Geology and Mineralogy at the Universities of Cologne and Bonn. The results have appeared in the current issue of 'Nature Geoscience'.

ROCKVILLE, Md. - June 4, 2019 - The Association for Molecular Pathology (AMP), the premier global, molecular diagnostic professional society, expressed serious concerns with Congress' recent proposal to amend Section 101 of the Patent Act. If enacted, the draft legislation would overturn 150 years of patent case law and permit patenting of human genes and naturally-occurring associations between genes and diseases.

A bad night's sleep may result in a spike in blood pressure that night and the following day, according to new research led by the University of Arizona.

The study, to be published in the journal Psychosomatic Medicine, offers one possible explanation for why sleep problems have been shown to increase the risk of heart attack, stroke and even death from cardiovascular disease.

The link between poor sleep and cardiovascular health problems is increasingly well-established in scientific literature, but the reason for the relationship is less understood.

Wildlife researchers have long tried to understand why birds fly in flocks and how different types of flocks work. A new study from the University of North Carolina at Chapel Hill explores the mechanics and benefits of the underlying flock structure used by four types of shorebirds. Understanding more about how these birds flock moves researchers a step closer to understanding why they flock.

BINGHAMTON, N.Y. - In the future, small paper and plastic devices will be able to connect to the internet for a short duration, providing information on everything from healthcare to consumer products, before they are thrown away. Researchers at Binghamton University, State University of New York have developed a micro biobattery that could power these disposable sensors.

A new study by researchers at the University of Virginia and other institutions has discovered a type of pigment cell in zebrafish that can transform after development into another cell type.

David Parichy, the Pratt-Ivy Foundation Distinguished Professor of Morphogenesis in UVA's Department of Biology, said that researchers in his lab noticed that some black pigment cells on zebrafish became gray and then eventually white. When they looked closer, they found dramatic changes in gene expression and pigment chemistry.

Scientists have used gene-editing techniques to stop the bird flu virus from spreading in chicken cells grown in the lab.

The findings raise the possibility of producing gene-edited chickens that are resistant to the disease.

Researchers prevented the virus from taking hold by deleting a section of chicken DNA inside lab-grown cells.

The next step will be to try to produce chickens with the genetic change. No birds have been produced yet, the team says.

Contrary to popular belief, consuming red meat and white meat such as poultry, have equal effects on blood cholesterol levels, according to a study published today in the American Journal of Clinical Nutrition.

The gene variant became more common in humans after cooking and farming became widespread, and might now help people avoid diabetes, according to the findings published in eLife.

"We found that people differ in how efficiently their bodies can manage blood sugar levels, resulting from an evolutionary process that seems to have been brought about by changing diets," said the study's lead author, Professor Frances Brodsky, Director of UCL Biosciences.

U.S. Right To Know, an industry trade group created by Organic Consumers Association to harass and intimidate academic scientists using Freedom of Information Act (FOIA) requests, has a new paper co-written by academics supporting organic corporations noting that data mining 17,000 pages of emails can suggest International Life Science Institute (ILSI) is doing wotk for hire for other corporations such as Nestle, General Mills, Mars Inc, Monsanto, and Coca-Cola.

The majority of women who underwent lumpectomy or mastectomy surgeries for breast cancer report that the scars from those surgeries negatively affect their daily lives. Yet one-third of patients said that their physician did not tell them about surgical options that minimize scarring, according to a report published recently by the journal BMC Cancer.

Advancing dementia affects relationships between carers and those in their care

It also affects relationships between those with dementia in care and their families, and the relationship between residents

A better understanding of behaviour and behavioural change the key to sustaining good relationships

Research the first to address the impact of a wide range of behaviours

Findings welcomed by Care UK, the UK's largest independent provider of health and social care, particularly in relation to staff recruitment and retention

With summer break and longer days ahead, parents of young teens may be wondering whether to let good sleep habits slide over the next couple of months. New research from the University of British Columbia suggests there are more benefits to a good night's sleep than simply feeling refreshed.
