If it feels like you forget new information almost as quickly as you hear it, even if you write it down, that’s because we tend to lose almost 40% of new information within the first 24 hours of first reading or hearing it. If we take notes effectively, however, we can retain and retrieve almost 100% of the information we receive.

Dogs' special relationship to humans may go back 27,000 to 40,000 years, according to genomic analysis of an ancient Taimyr wolf bone reported in the Cell Press journal Current Biology on May 21. Earlier genome-based estimates have suggested that the ancestors of modern-day dogs diverged from wolves no more than 16,000 years ago, after the last Ice Age.
The genome from this ancient specimen, which has been radiocarbon dated to 35,000 years ago, reveals that the Taimyr wolf represents the most recent common ancestor of modern wolves and dogs.
The stronger our memory is of a certain food, the more likely we are to choose it - even if it is the more unattractive option. Psychologists at the University of Basel conducted a study on how memory influences our choices by offering various foods and using scans to track brain activity. The researchers were able to show that the influence of memory is mediated by increasing communication between the relevant brain areas. The study has been published in the scientific journal Neuron.
Here's the skinny: Not all women will buy products because the models in the advertisements are thin, according to a new study of a diverse group of 239 women by a Baylor University marketing professor.
In fact, marketers and advertisers who default to the "thin ideal" -- the belief that thinner is better -- could be alienating up to 70 percent of their audience, said James Roberts, Ph.D., The Ben H. Williams Professor of Marketing in Baylor's Hankamer School of Business.
Many undocumented workers from Latin America risk migrating to the United States to take jobs in which they will be exploited because they are fleeing from desperate situations and see opportunities to help their families.
That scenario, says Gerardo F. Sandoval of the University of Oregon, emerged from a long-running case study in which under-the-radar networks driven by economic and political pressures were documented. These shadow networks tie workers to low-paying, labor-intensive jobs in new communities and to the towns they left.
Cold weather kills 20 times as many people as hot weather, according to an international study analyzng over 74 million deaths in 384 locations across 13 countries. The findings in The Lancet also reveal that deaths due to moderately hot or cold weather substantially exceed those resulting from extreme heat waves or cold spells.
The countries involved were Australia, Brazil, Canada, China, Italy, Japan, South Korea, Spain, Sweden, Taiwan, Thailand, UK, and USA.
Researchers from The University of Texas Medical Branch at Galveston have found that drinking chamomile tea was associated with a decreased risk of death from all causes in Mexican-American American women over 65. The findings were recently published online in The Gerontologist.
Chamomile is one of the oldest, most-widely used and well-documented medicinal plants in the world and has been recommended for a variety of healing applications. It is currently widely used as an herbal remedy in Mexico and among Mexican-Americans.
Scientists working in the desert badlands of northwestern Kenya have found stone tools dating back 3.3 million years, long before the advent of modern humans, and by far the oldest such artifacts yet discovered. The tools, whose makers may or may not have been some sort of human ancestor, push the known date of such tools back by 700,000 years; they also may challenge the notion that our own most direct ancestors were the first to bang two rocks together to create a new technology.
ew local government organizations in Colorado had policies on environmental controls, such as the provision of outdoor shade, or administrative procedures, including training and resource allocation, to improve sun protection for their workers and most policies addressed employees' use of personal protection practices, according to a new analysis.
Most people associate osteoporosis with women. But the truth is, one in four men over the age of 50 will break a bone as a result of this condition. That's more men than will have prostate cancer, according to the National Osteoporosis Foundation.
Now a leading researcher at National Jewish Health is calling for men to be included in the screening guidelines for osteoporosis. Elizabeth Regan, MD, PhD, a researcher at National Jewish Health, studied more than 3,000 smokers and former smokers ages 45 to 80 and tested their bone density. What she found was surprising.
How the Victorians and how they sought to define and deal with negligent medical care in the wake of the poor law is the subject of a new book.
Medical Negligence in Victorian Britain is written by Dr Kim Price from the Centre for Medical Humanities and explores the hundreds of charges of neglect against doctors who were contracted to the 'new' poor law after the Poor Law Amendment Act of 1834. As well as its historical perspective, the book provides some insights into the welfare system today.
Playing natural sounds such as flowing water in offices could boosts worker moods and improve cognitive abilities in addition to providing speech privacy, according to a new study from researchers at Rensselaer Polytechnic Institute. They will present the results of their experiment at the 169th Meeting of the Acoustical Society of America, held May 18-22, 2015 in Pittsburgh.
Children born since the 1980s are two to three times more likely than older generations to be overweight or obese by the age of 10, according to new research published in PLOS Medicine. The study, conducted by researchers from CLOSER, a consortium of UK longitudinal studies, characterized population shifts in body mass index (BMI) using data from more than 56,000 people born in Britain from 1946 to 2001.
Many of those who should get it, don't. And many of those who shouldn't, do. That's the story of a common screening test for osteoporosis, according to new research.
HIV infections continue to rise in young gay and bisexual men despite three decades of outreach and HIV prevention as well as recent availability of biomedical technologies to prevent infection.
