If you're finding it harder to remember where you put the car keys, the culprit could be a brain protein with a name that's easy to forget: RbAp48.
A shortage of this protein appears to impair our ability to remember things as we age, researchers report in the current issue of Science Translational Medicine. And boosting levels of RbAP48 in aging brains can reverse memory loss, at least in mice, they say.

There's no question that dealing with mortgages, car payments and other bills takes up time and energy. But having a tight budget may also zap our ability to think clearly, scientists report Thursday in the journal Science.
In a series of clever experiments involving farmers in India and shoppers in New Jersey, scientists found that people are worse at solving puzzles — similar to those on the IQ test — when they're first reminded of money problems.
A children's adventure garden, a $62 million education center focused on earth and life sciences, is about to open in Texas at the Dallas Arboretum. Maria Conroy, the Arboretum's vice president and the driving force behind the garden, told The New York Times last week that, because Dallas is an urban jungle without much green space, some children there are afraid of nature:
It's not news that Hong Kong, which brags one of the world's most stunning skylines, has been gradually losing it behind a curtain of smog.
But the Chinese territory's latest solution is new: To placate camera-clicking tourists unable to get those iconic shots of the skyscraper-studded waterfront, Hong Kong has set up a panoramic backdrop with clear, blue skies.
The Chinese website Netease published a series of pictures of tourists posing in front of the backdrop.
A study in the journal Nature could help explain why the Earth's average temperature hasn't increased during the past 15 years — despite a long-term trend of global warming.
The Earth's average temperature has risen by more than 1 degree Fahrenheit since the beginning of the Industrial Revolution. But the temperature rise has not been moving in lock step with the rise of carbon dioxide in the atmosphere. Carbon dioxide — mainly from burning fossil fuels — traps heat in the air.
Researchers in Sweden have confirmed the existence of element 115. It sticks around for a surprisingly long time. Scientists believe it may bring them closer to the mythical "island of stability" a whole slew of super-heavy elements that could last for days or even years.

A week without water can easily kill the average person.
But a garden that goes unwatered for months may produce sweeter, more flavorful fruits than anything available in most mainstream supermarkets — even in the scorching heat of a California summer. Commercial growers call it "dry farming," and throughout the state, this unconventional technique seems to be catching on among small producers of tomatoes, apples, grapes, melons and potatoes.
