A new study found that children from poor families with depressed mothers experience delays in cognitive and motor development, while middle-class households offer some protection. The effects of maternal depression on boys and girls differ, with moderate depression in affluent families resulting in lower cognitive scores.
The TIMED mission will study the Mesosphere and Lower Thermosphere/Ionosphere region, crucial for understanding space weather's effects on communications and satellite tracking. Ground-based instruments will be used to conduct a global study of this area.
Researchers measured the force required to overcome tissue-needle connection during acupuncture needling, finding a significant pullout force when needles were rotated. The study suggests that layers superficial to muscle may be involved in the body's response to acupuncture, with future research focusing on connective tissue's role.
A Virginia Tech team has won a grant to develop mathematically rigorous decomposition theories for solving large-scale design problems on massively parallel supercomputers. The project aims to reduce communication bottlenecks and improve concurrency in the design process.
Individuals with severe inattention and hyperactivity symptoms may use tobacco as self-medication to manage their symptoms. The study suggests that screening participants in smoking cessation programs for these symptoms could identify smokers who need additional intervention and tailor treatments to address their specific needs.
A NASA-funded study found that glacier melting can shut down North Atlantic Deep Water production, leading to a reduced Gulf Stream and cooling Western Europe. The study suggests that freshwater additions from increased rain and snow could cause this phenomenon in the future.
A new study from the University of Toronto shows that consuming carbohydrate, fat and protein drinks of equal calories improves verbal recall in elderly individuals. The positive effects on memory are explained by an evolutionary perspective, suggesting specific types of food energy enhance specific aspects of brain function.
The University of Colorado at Boulder has acquired two state-of-the-art electron microscopes, enabling researchers to image cellular structures in three dimensions at unprecedented resolution. This advancement is made possible by a suite of complementing computers that run programs developed by CU-Boulder researchers.
Researchers from the University of Pennsylvania have identified a gene called CREB that plays a role in regulating rest's rejuvenating effects. The study found that CREB activity is inversely related to the physiological urge for sleep and that blocking this activity increases the need for sleep after a period of wakefulness.
A new study found that 41% of physicians would perform at least one action proscribed by the AMA's ethics guidelines, while 25% would perform five or more actions. The study suggests that some physicians are morally confused about their role in capital punishment.
The University of Michigan School of Education has received a $175,000 grant from the Goldman Sachs Foundation to evaluate and support programs promoting educational excellence globally. The program focuses on developing academic abilities and entrepreneurial talents in underrepresented youth.
Researchers at the University of Michigan successfully grew new, mature blood vessels in live animals by implanting scaffolds that delivered critical growth factors. The innovative approach, reported in Nature Biotechnology, has potential medical applications for alternatives to heart bypass surgery and treatments for vascular disease.
Physicians who participate in executions do so out of a sense of citizen obligation, but this involvement mostly advances pro-death penalty political purposes. Medical professionals have long opposed physician participation in executions due to ethical concerns.
A new study reveals that HIV-specific CD4+ T cells persist in infected individuals, but high virus levels suppress their proliferative response. The research provides clues on how the virus manipulates the immune system for its own survival and challenges the notion of long-term nonprogressors.
Researchers have discovered that antibodies attacking DNA in people with lupus can also target molecules controlling glutamate activity, leading to neuron death and possible cognitive symptoms. This finding suggests a potential pathway for neurological complications and may lead to new therapeutic options.
Researchers at Women's and Children's Hospital in Adelaide have developed a way to safely use Human Immunodeficiency Virus Type 1 (HIV-1) to transfer therapeutic genes into human cells. This method has wide applicability for various human genetic diseases and is currently being tested on animal models before moving to human trials.
Research by Susan M. McHale found that children who spend more time on structured activities like hobbies and sports tend to have better academic, emotional, and behavioral development. In contrast, excessive outdoor play or unstructured free time may lead to poorer grades and behavior issues.
Researchers discovered a link between the CFTR gene and increased susceptibility to respiratory infections in cystic fibrosis. They found that altered CFTR can change the internal chemistry of lung cells, making them more attractive to certain bacteria.
A new study finds that even modest increases in family economic resources improve cognitive development, language abilities, and social behavior in young children from poor families. The study discovered a correlation between income-to-need ratios and developmental outcomes in children from birth to age 3.
A team of researchers has identified a novel gene, Lpp1, that is mutated in mice with severe spina bifida. This discovery provides new insights into the genetic basis of the condition and may lead to the development of new therapies to prevent it.
Researchers find HIV attachment to rafts is crucial for replication, and cholesterol-lowering drugs may help disrupt this process. Depleting cholesterol from rafts using compounds significantly reduces HIV's ability to infect new cells.
MetaPhore will develop and test a highly active SOD mimetic to protect heart tissues from damage. The research aims to provide additional mechanistic information on the role of superoxide in reperfusion injury, which may also apply to other ischemic events.
A recent study by the San Francisco VA Medical Center found that two-thirds of elderly people who are eligible for nursing home care receive it at home, often from family members. This type of in-home care is estimated to save the government billions of dollars annually.
A new study found that smoking cessation programs may be less effective for black smokers than for white smokers, with a 23% quit rate compared to 34% after one year. However, the difference narrowed over time, suggesting that interventions without specific adaptations for black participants may still be effective.
Researchers at University of Toronto have discovered a photon switch that can manipulate photons to transmit data in computers. The discovery has the potential to solve problems that traditional computers cannot, including database searches and cracking codes on the Internet.
