After decades of public safety campaigns focused on drinking and driving, it may be time to focus on the seventh leading cause of injury-related death, according to Bureau of Occupational Health and Injury Prevention at New York State Department of Health and Columbia University scholars looking at New York State.
The World Health Organization released its 2015 updated essential medicines list and for the first time included the progesterone contraceptive vaginal ring (CVR), a contraceptive safe and effective for lactating women in the postpartum period.
The progesterone CVR, developed by the Population Council, is an intravaginal ring that provides women who breastfeed at least four times a day with a contraceptive option as early as four weeks after giving birth. It can be used for up to a year for improved birth spacing.
Comparing the genomes of different species — or different members of the same species — is the basis of a great deal of modern biology because DNA sequences conserved across species are likely to be functionally important, while variations between members of the same species can indicate different susceptibilities to disease.
The central United States has undergone a dramatic increase in seismicity over the past 6 years. From 1973-2008, there was an average of 24 earthquakes of magnitude 3 and larger per year. From 2009-2014, the rate steadily increased, averaging 193 per year and peaking in 2014 with 688 earthquakes. So far in 2015, there have been 430 earthquakes of that size in the central U.S. region through the end of May.
There are many questions and misconceptions about what’s happening. How does the observed increase relate to oil and gas production activities? Does this connect to fracking—more formally known as hydraulic fracturing? What exactly is fracking? What are induced earthquakes?
When a plant is attacked by herbivores, this triggers a number of physiological responses in the plant and calcium ions are important messengers for the processing of wound signals in plant cells. They regulate signal transduction and indirectly control plant defense mechanisms.
Now, scientists have succeeded in visualizing the immediate wound or herbivory responses in plants. They used Arabidopsis thaliana (thale cress) plants that produce a special protein which breaks down after the binding of calcium ions and emits free energy in the form of light. The amount of light corresponds to the calcium concentrations in the cells of the respective leaf areas.
It is believed by the social sciences that all people have bias - and a "bias blind spot," meaning that they are less likely to detect bias in themselves than others.
If so, how blind are we to our own actual degree of bias, and how many of us think we are less biased than others?
A new paper outlines a tool to detect gaps, a kind of implicit association test but for bias blind spots rather than making you feel racist, and it reveals that believing that you are less biased than your peers has detrimental consequences on judgments and behaviors, such as accurately judging whether advice is useful.
In many animal species, the chromosomes differ between the sexes - the male has a Y chromosome. This contains genes which result in the development of male characters and reproductive organs. If there is no Y chromosome, the organism will be a female.
But in birds and some other animals, it is the other way round and females have their own sex chromosome, the W chromosome.
The ESO's Very Large Telescope has revealed what appears to be an aging star giving birth to a butterfly-like planetary nebula.
These observations of the red giant star L2 Puppis, from the ZIMPOL mode of the newly installed SPHERE instrument, also clearly showed a close stellar companion.
Honest behavior is much like sticking to a diet - you have to be ready for temptation and consider the long-term consequences.
A recent paper says it is the first study to test how the two separate factors of identifying an ethical conflict and preemptively exercising self-control interact in shaping ethical decision-making.
In a series of experiments that included common ethical dilemmas, such as calling in sick to work and negotiating a home sale, the researchers found that two factors together promoted ethical behavior: Participants who identified a potential ethical dilemma as connected to other similar incidents and who also anticipated the temptation to act unethically were more likely to behave honestly than participants who did not.
Wide-scale population migrations and changes took place in Europe and Asia during the Bronze Age that shaped the demographic structure of present-day Europeans and Asians, as revealed by an analysis of 101 genomes from ancient Eurasian humans. A new study published in this week’s Nature presents one of the largest studies of ancient DNA samples to date. The research provides insights into the prevalence of certain traits such as skin color or lactose tolerance, as well as data relevant to the understanding the spread of Indo-European languages.
Women aged 50-69 years who attend mammography screening reduce their risk of dying from breast cancer by 40 percent compared to women who are not screened - according to a major international review of the latest evidence on breast cancer screening. Overall, women who are invited to attend mammography screening have a 23 percent risk reduction in breast cancer death (owing to some attending and some not), compared with women not invited by routine screening programs.
In the UK, this relative risk translates to around eight deaths prevented per 1,000 women regularly attending screening, and five deaths prevented per 1,000 women invited to screening.
Cancer has overtaken cardiovascular disease, which includes heart disease and stroke, as the UK's No 1 killer--but only among men, reveals research published online in the journal Heart.
Cardiovascular disease is still the most common cause of death among women, and kills more young women than breast cancer, the figures show.
The researchers used the latest nationally available data (2012-13) for each of the four UK countries and the Cardiovascular Disease Statistics 2014 report compiled for the British Heart Foundation (BHF) to quantify the prevalence of cardiovascular disease, and find out how it's treated, how much it costs, and how many deaths it causes.
U.S. government-issued dietary recommendations continue to evolve over time but a new paper by scholars claims that the main source of dietary information used by the U.S. Government’s 2015 Dietary Guidelines Advisory Committee (DGAC) is scientifically flawed because the underlying data are primarily informed by memory-based dietary assessment methods (M-BMs) (e.g. interviews and surveys).(1)In an editorial response nutrition experts suggest that the purported flaws are well-appreciated by nutritional researchers and can be mitigated by using multiple data sources, resulting in valid data.(2)
