How do you explain suicidal crickets and zombie caterpillars? One word: parasites. Science writer Ed Yong shows us how these tiny creatures force insects and animals to do their bidding, and asks: Are parasites manipulating humans, too?
Scientists turned a mouse's bad memories into happy ones with a pulse of light, and cured other mice of peanut allergies by dosing them with Clostridium bacteria.
Earlier this year the UK government finally gave up on trying to control the American grey squirrel in the UK. Which prompts the question: Why has the grey squirrel been such a success in Britain?
Noting that her fruit flies were more likely to get sick and die if they were infected at nighttime led her to important discoveries about the effects of circadian rhythm on immune response.
The mental health industry works very hard to convince government to throw money at "mental health" problems that are very broadly and loosely defined, instead of having a clear focus on delivering basic services to the seriously ill.
Theory Of Mind,
We spend time every day in the company of others, but without explicit communication. Our lives unfold socially but silently, but even in the silence, good experiences get better and bad experiences get worse.
According to research published in excellent, peer-reviewed journals and dating back 17 years, one of the major potential causes of depression, anxiety, shyness and low self-esteem (the undervalued self) is found in about 20 percent of the population. This is the trait...
Do all these factors mean we have a community of selfish scientists? The simple answer is no. The more genuine answer is: It's complicated. The institutional inertia of the established scientific community strongly favors researchers who go along with the data-hoarding norms.
Jeanne Loring and her Scripps Research Institute colleagues transplanted a set of cells into the spinal cords of mice that had lost use of their hind limbs to multiple sclerosis. As the experimentalists expected, within a week, the mice rejected the cells. But after another week, the mice began to walk.
Four hundred five years ago this week, Galileo Galilei demonstrated his new telescope to members of the Venetian senate in the Plaza San Marco. This presentation on Aug. 25, 1609, marks the birth of the astronomical telescope and the launching of a scientific revolution.
"We Brits like to take our sci-fi seriously, but not ourselves."
Gravity is so weak at the atomic and subatomic level because the masses of atoms and subatomic particles are so small. It is strong on the planetary scale because the masses of planets are so large.
My dad who died of ALS would be frustrated, as I am, that the Ice Bucket Challenge gives the political adversaries of scientific research a pretext to disguise their views and pretend they haven't made it harder to find a cure, for any disease at all.

We hear so much about respecting boundaries that we tend to forget there's a world of difference between violating them and simply testing them. Every breakthrough -- whether in science, in art or in a one-on-one relationship -- involves crossing a boundary. And not all boundaries are as hard to cross as they seem.
If the device works and works well, is there really a need to make it look nice? Technology has a new edge in today's products -- not only do they have to work, but they also have to make us look good using them.
Many of us hunger for special experiences, things none of our friends have done or will do. But do these adventures really make us happy in the long run? Are they worth having?
Great trilogies come in threes.
Space Exploration Technologies,
Testing a truly new rocket has always involved failure. In fact, the development of any complex and innovative product should feature an iterative development process. By definition such a process is "failure driven."
Chronic Fatigue Syndrome,
National Institutes Of Health,
Nothing is more damaging to research than funding instability. The universities and many research laboratories -- including those run by the government -- operate like concertinas. They expand and contract according the whim of Congress.
Amyotrophic Lateral Sclerosis,
Amyotrophic Lateral Sclerosis ALS,
Lou Gehrig's Disease,

Ice Bucket Challenge,
How much closer would we be to a cure today if instead of wasting millions of dollars on failed animal experiments, the money had been used to create more effective human-based testing methods that accurately recreated the disease?
