From The Telegraph:
Couples develop their own language of love that ebbs and flows depending on the state of their relationship, scientists believe.
Those deeply in love speak and write alike, mimicking and repeating words and phrases that each other use.
But if the relationship sours then the common language breaks down and they begin to sound more like strangers again.

Dinosaurs Significantly Taller Than Previously Thought, Research Suggests

From Science Daily:
ScienceDaily (Oct. 1, 2010) — It might seem obvious that a dinosaur's leg bone connects to the hip bone, but what came between the bones has been less obvious. Now, researchers at the University of Missouri and Ohio University have found that dinosaurs had thick layers of cartilage in their joints, which means they may have been considerably taller than previously thought. The study is being published this week in the journal PLoS ONE (Public Library of Science).

After decades of apparent absence, bedbugs are back with a vengeance. The bugs have returned to U.S. cities, infesting hotels, schools, apartments, homes, stores and offices. The tiny bloodsuckers are known to leave red, itchy marks on their victims, as well as a social stigma.
But where did bedbugs come from, what harm do they really cause, and why the sudden resurgence?

Instant Expert: Rebuilding Human Minds
Memory Lost, Memory Gained koppillustration.com
From Popular Science:
Scientists hope to strengthen aging brains by tweaking the behavior of DNA.
Age-related memory loss—the kind where you remember friends from decades ago but can’t remember your grandchildren—is largely a mystery, but a class of com-pounds used to treat cancer has given neuroscientists clues to its molecular underpinnings. Scientists also suspect that the compounds responsible for this insight, called histone deacetylase inhibitors, could significantly slow memory loss—perhaps for years. (Two drugs used now to treat memory loss and Alzheimer’s disease work only for a short time.)

Is This Apple Ap Going To Help Terrorists?
Threat: Security experts have slammed a £2 phone app which gives specific details about in-flight aircraftPhone App That Tracks Planes 'Is Aid To Terrorists Armed With Missiles' - -The Daily Mail
A mobile phone application costing less than £2 which tracks the precise location of passenger aircraft in the sky is a serious terrorist threat and should be banned, according to a security expert.
The Plane Finder AR app for the Apple iPhone and Google’s Android allows users to point their phone at the sky and see the position, height and speed of nearby aircraft. It also shows the airline, flight number, departure point, destination and even the likely course.

The Slippery Slope To Obesity
Not a good start (Image: Wade/Getty)From New Scientist:
REWARD pathways in the brains of overweight people become less responsive as they gain weight. This causes them to eat more to get the same pleasure from their food, which in turn reduces the reward response still further.
Eric Stice, a psychologist at the University of Texas at Austin, and colleagues used fMRI brain scans to monitor 26 obese or overweight volunteers as they sipped either a tasty milkshake or a flavourless liquid resembling saliva. They compared the effect of both drinks on brain activity in the dorsal striatum, a key part of the brain's reward circuitry. Six months later, they retested the volunteers.

The world's oldest known high-altitude human settlements, dating back up to 49,000 years, have been found sealed in volcanic ash in Papua New Guinea mountains, archaeologists said Friday.
Researchers have unearthed the remains of about six camps, including fragments of stone tools and food, in an area near the town of Kokoda, said an archaeologist on the team, Andrew Fairbairn.

Dolphin Species Attempt 'Common Language'
A Guyana dolphin leaps to escape the attention of a bottlenose dolphinFrom The BBC:
When two dolphin species come together, they attempt to find a common language, preliminary research suggests.
Bottlenose and Guyana dolphins, two distantly related species, often come together to socialise in waters off the coast of Costa Rica.
Both species make unique sounds, but when they gather, they change the way they communicate, and begin using an intermediate language.
That raises the possibility the two species are communicating in some way.

Video: Robots Now Guarding Nevada Nuke Site
From The Danger Room:
Citizens of Nevada, you can now relax. The Nevada National Security Site, home to tens of millions of cubic feet of low-level radioactive waste — and location of over a thousand Cold War nuclear weapons tests — is now being guarded by robots. The first of a planned trio of Mobile Detection Assessment Response Systems, or MDARS, is currently patrolling some of the more remote sections of the 1,360 square mile facility.

Mission To Search For Alien Life In Outer Atmosphere

Life from outer space could be surviving on the outer fringes of the Earth's atmosphere, according to scientists who are to launch a mission to search for bacteria that could be living there.
In science fiction films the search for aliens involves travelling across the galaxy to planets millions of miles away.
But scientists believe they could be close to discovering alien life forms much closer to home – on the outer fringes of Earth's atmosphere.

Geology: A Trip To Dinosaur Time
From Nature News:
A project to drill a 10-kilometre-deep hole in China will provide the best view yet of the turbulent Cretaceous period. Jane Qiu reports.
The rock columns on the table are not much to look at. More than a metre long, 10 centimetres in diameter and mostly made up of oil shale and sandstone, they are a dull greyish green. But these, says Wang Chengshan, a geologist at the China University of Geosciences in Beijing, "are not ordinary rocks".

ScienceDaily (Oct. 1, 2010) — New research challenges the controversial theory that an ancient comet impact devastated the Clovis people, one of the earliest known cultures to inhabit North America.
Writing in the October issue of Current Anthropology, archaeologists Vance Holliday (University of Arizona) and David Meltzer (Southern Methodist University) argue that there is nothing in the archaeological record to suggest an abrupt collapse of Clovis populations.

Americans' Sex Lives Exposed by New Survey
From Live Science:
Americans, on average, use a condom one in four times when they have vaginal sex, according to a recent survey that also finds men think women are having orgasms more than they are.
This new sex survey shows that condom use has increased among some groups, but promoting condom use – which prevents the spread of sexual transmitted diseases like AIDS – should remain a health priority, according to Michael Reece, the director of the Center for Sexual Health Promotion at Indiana University, which conducted the survey.

This Year's Ig Nobel Prize: Fruit Bat Fellatio, Whale Snot, And More Weird Science
From Popular Science:
The Ig Nobel Prize studies are not a joke, but that's not to say you won't laugh.
If the MacArthur "Genius" Grants announced earlier this week were too staid for you, the Ig Nobel Prize (now in its 20th year--here's last year's coverage) might be the scientific awards presentation for you. The Ig Nobels aren't a joke; every winning study has a legitimate scientific purpose and execution, making real discoveries and solving real problems. But they're also all chosen for their ability to "make you laugh and then make you think." This year's winners include remote-controlled whale snot retrieval, the benefits of roller coaster riding on asthma sufferers, and our own personal favorite which you may remember: transit planning by slime mold

British scientist Robert Edwards, the man who devised the fertility treatment IVF, has been awarded this year's Nobel prize for medicine.
His efforts in the 1950s, 60s and 70s led to the birth of the world's first "test tube baby" in July 1978.
Since then nearly four million babies have been born following IVF.
The prize committee said his achievements had made it possible to treat infertility, a medical condition affecting 10% of all couples worldwide.
