Can you smell time? Your dog can.
On a very basic level, so can you: When you crack the lid on that old quart of milk, tentatively sniff and—peeyouu!—promptly dump that foul stuff down the sink, you are, in effect, smelling time. Specifically, you can smell that far too much time has elapsed since that milk was fresh.
But a dog can smell time with a sophistication that puts our simple sniffers to shame. “Odors exist in time, and dogs perceive that,” explains cognitive scientist and canine researcher Alexandra Horowitz of Columbia University. “Dogs use smell to ‘tell time,’ in some sense, because a more recently laid odor smells stronger, and an older odor smells weaker.”
A dog’s nose is a notoriously sensitive piece of equipment. With up to 300 million olfactory receptors compared to our lousy 5 million, a dog can detect a single teaspoon of sugar dissolved into a million gallons of water, the equivalent of two Olympic-sized swimming pools. Unlike us, dogs are able to take in scent continuously, even as they exhale. What’s more, a dog’s nostrils are smaller than the distance between them, effectively giving dogs “stereo” sniffing power that carries subtle grades of information, including directionality.

Time doesn’t fly if you’re a fly, a new study suggests. In fact, flies excel at dodging our slaps and swats because they perceive the passage of time more slowly than we do. Animals with smaller bodies and faster metabolic rates perceive time more slowly than we do, researchers say, letting them soak up more information per second.
We tend to assume time is the same for everyone, but according to research published in the journal Animal Behaviour, it has different speeds for different species. Small-bodied animals with fast metabolic rates — whether they’re house flies or hummingbirds — perceive more information in a unit of time, the study finds, meaning they experience action more slowly than large-bodied animals with slower metabolism, including humans.
If this reminds you of a certain 1999 science-fiction movie, you’re on the right track. The study was led by scientists from Ireland’s Trinity College Dublin, which issued a press release that explains the findings with a dusty pop-culture reference: “For example, flies owe their skill at avoiding rolled-up newspapers to their ability to observe motion on finer timescales than our own eyes can achieve, allowing them to avoid the newspaper in a similar fashion to the ‘bullet time’ sequence in the popular film ‘The Matrix.”

Improvised with an antique clock with unique characteristics due to it’s malfunction and two additional clocks equally as old but working perfectly. Driven by the usual premise: the reaction to stimuli on the unpredictability of (seemingly) random sounds, and in this particular case the management of confrontation between different measures of time.

A new surge of interest in fasting suggests that it might indeed help people with cancer. It might also reduce the risk of developing cancer, guard against diabetes and heart disease, help control asthma and even stave off Parkinson’s disease and dementia.
“We know from animal models,” says Mark Mattson at the National Institute on Aging, “that if we start an intermittent fasting diet at what would be the equivalent of middle age in people, we can delay the onset of Alzheimer’s and Parkinson’s.”
Until recently, most studies linking diet with health and longevity focused on calorie restriction. They have had some impressive results, with the life span of various lab animals lengthened by up to 50 percent after their caloric intake was cut in half. But these effects do not seem to extend to primates. A 23-year study of macaques found that although calorie restriction delayed the onset of age-related diseases, it had no impact on life span. So other factors, such as genetics, may be more important for human longevity.

The year, of course, is the time it takes for the Earth to go around the Sun, right? Well, not exactly. It depends on what you mean by “year” and how you measure it. This takes a wee bit of explaining, so while the antacid is dissolving in your stomach to remedy last night’s excesses, sit back and let me tell you the tale of the year.

Nick Hornby, Dave Eggers and Zadie Smith are among a growing group of novelists who struggle with internet-addiction. Carl Wilkinson investigates the powerful effect of the web on the creative mind.
Tucked away in the acknowledgements at the back of her new novel NW, along with the names of friends, family, editors and publishers who have helped her, Zadie Smith thanks freedom and self-control “for creating the time”.
Every writer needs the freedom to be creative and the self-control to stick with a project until completion, but Smith has something rather more 21st century in mind: Freedom © and SelfControl© are computer applications that can be downloaded and configured to increase productivity by blocking access to the internet.
These two pieces of software originated in quite different places. Freedom was developed by Fred Stutzman, visiting assistant professor at the University of North Carolina’s School of Information and Library Science, and counts Nick Hornby, Dave Eggers and Naomi Klein among its users. Stutzman has also released Anti-Social, which blocks the social-media elements of the internet. SelfControl, meanwhile, was created in 2009 by American artist Steve Lambert, one of the people behind The New York Times Special Edition – a hoax copy of the paper published in November 2008.

Are you a morning lark or a night owl? Scientists use that simplified categorization to explain that different people have different internal body clocks, commonly called circadian clocks. Sleep-wake cycles, digestive activities, and many other physiological processes are controlled by these clocks. In recent years, researchers have found that internal body clocks can also affect how patients react to drugs. For example, timing a course of chemotherapy to the internal body time of cancer patients can improve treatment efficacy and reduce side effects.
But physicians have not been able to exploit these findings because determining internal body time is, well, time consuming. It’s also cumbersome. The most established and reliable method requires taking blood samples from a patient hourly and tracking levels of the hormone melatonin, which previous research has tied closely to internal body time.
