Recently on Real Clear Science, Ross Pomeroy published an article Why Nothing Can Be Truly ‘Unnatural’, in which he denounces attempts to oppose homosexuality on scientific grounds. However, after reading it, I am left with the feeling that he is not simply reporting science, but perhaps being a little bit like an old-fashioned nanny telling her charges what is or is not proper. If so, he will be firing a shot in-->
Scientists have discovered a way to prevent the development of multiple sclerosis in mice. Using a drug that blocks the production of a certain type of immune cell linked to inflammation and autoimmunity, the researchers successfully protected against the onset of MS in an animal model of the disease.
In the immune system, two kinds of T cells strike a delicate balance--T helper cells (Th17) activate the immune system, protecting against infections and cancers, while regulatory T cells (Tregs) suppress the system, keeping it in check. A disparity between these cell types, where there are too many Th17 and not enough Tregs, can lead to a hyperactive immune system, resulting in inflammation, tissue damage, and autoimmune disease.
Global incomes continue to rise, more people are living more comfortably, globalization has been a huge win for many developing nations and that means more people than ever can afford air conditioning.
While some policy makers live in an idealized developed world where more wind and solar power at ever higher costs will solve the emissions problem, that lacks fairness for people who are only now able to afford to live well. More people are going to need electricity and that means we need to embrace true green energy and not fudge numbers to where political winners look like viable solutions for the future. Without viable clean energy the stress on energy prices and infrastructure will mean poorer people stay shackled to the past.
The original NASA/ESA Hubble Space Telescope image of the famous Pillars of Creation - in the Eagle Nebula, Messier 16 - was taken two decades ago and immediately became its most famous picture. Since then, these billowing clouds, which extend over a few light-years, have awed the public.
One of the concerns about the switch from incandescent to fluorescent lighting was that while the ballasts are higher frequency now - humans do not have to hear that annoying hum - they were right in the range that pets still hear.
Interventional treatments such as surgery provide good functional outcomes and a high cure rate for patients with lower-grade arteriovenous malformations (AVMs) of the brain, according to a new study. These findings contrast with a recent trial reporting better outcomes without surgery or other interventions for AVMs.
“It was a four-year ordeal,” Lewis recounts, sitting beside her husband one autumn morning in a sandwich shop north of Houston.-->
A study in Science has tied the aging process to the deterioration of tightly packaged bundles of cellular DNA known as heterochromatinand say that the genetic mutations underlying Werner syndrome, a disorder that leads to premature aging and death, results in the deterioration of these bundles.
The discovery used stem cell and gene-editing technologies and could lead to ways of countering age-related physiological declines by preventing or reversing damage to heterochromatin.
By Sara Rennekamp, Inside Science - Is your wine vegan? It seems like an odd question: wine is made of grapes, grapes fall solidly under the "not an animal product" label, therefore it would seem that wine is a vegan-friendly beverage.
However, many people who adhere to a vegan diet refrain from consuming any food or drink that is processed using animal products as well as the animal products themselves. Unfortunately for vegans, some wines are processed using animal products.
The culprit: a process called fining.-->
Researchers have shown that, like humans, mustached bats use the left and right sides of their brains to process different aspects of sounds.
No other animal, not even monkeys or apes, has proved to use such hemispheric specialization for sound processing - meaning that the left brain is better at processing fast sounds, and the right processing slow ones.
"These findings upset the notion that only humans use different sides of their brains to distinguish different aspects of sound," says the study's senior author, Stuart Washington, PhD, a neuroscientist at Georgetown.
Washington says the findings of asymmetrical sound processing in both human and bat brains make evolutionary sense.
Individuals with Type 2 Diabetes have difficulty regulating their glucose - blood sugar - levels, particularly after meals but a new study has found that Type 2 diabetics can eat more protein at breakfast to help reduce glucose spikes at both breakfast and lunch.
Researchers monitored Type 2 diabetics' levels of glucose, insulin and several gut hormones -- which help regulate the insulin response -- after breakfast and lunch. The participants ate either high-protein or high-carbohydrate breakfasts, and the lunch included a standard amount of protein and carbohydrates.
A new study forecasting how life expectancy will change in England and Wales has predicted people will live longer than current estimates - and that means they could have an oncoming economic train wreck because of the need for additional investments in health and social services and pensions for the elderly.
Antarctica's Dry Valleys may not be so dry. A helicopter-borne sensor that penetrates below the surface of large swathes of terrain has found compelling evidence that ice-free McMurdo Dry Valleys may be hiding a salty aquifer.
Brines, or salty water, form extensive aquifers below glaciers, lakes and within permanently frozen soils. If they are present, it might provide answers about the biological adaptations of previously unknown ecosystems that persist in the extreme cold and dark of the Antarctic winter.
Researchers have discovered areas in the tropical North Atlantic, several hundred kilometers off the coast of West Africa, with extremely low levels of oxygen, making them uninhabitable for most marine animals.
The levels measured in these 'dead zones' are the lowest ever recorded in Atlantic open waters.
Researchers have used mathematical equations to shed new light on how flowing fluid hinders the movement of bacteria in their search for food. Many bacteria are mobile and inhabit a variety of dynamic fluid environments: from turbulent oceans to medical devices such as catheters.
Since the first attempts at classifying bacteria in the 17th century, shape has been an important feature, yet it is still not fully understood how shape affects the ability of bacteria to navigate their environments.
Spring is here and that means fewer airplanes need to be de-iced. That may be good, according to a new study which finds that de-icing agents accumulated during the winter, which end up on unpaved areas and infiltrate into the soils during snowmelt, could end up in groundwater.
