A new cancer vaccine platform works by enhancing the ability of the immune system to recognize cancer by leveraging anti-viral memories it already has - due to the COVID-19 pandemic, the worst outbreak of the last 70 years.
Men may be more willing than women to sacrifice achievement goals for a romantic relationship, according to a new study by Catherine Mosher of Duke Medical Center and Sharon Danoff-Burg from the University of Albany. Their findings challenge our preconceptions that women are more likely to prioritize people and relationships while men are more focused on themselves and their achievements. Their paper will be published in the next issue of the Springer journal, Gender Issues.
The authors looked at whether personality traits influence students’ life goals, and focused on the relative importance of romantic relationships and achievement goals in particular.
A study in the Scandinavian Journal of Obstetrics and Gynaecology reveals that pine bark extract from the French maritime pine tree, reduces “climacteric symptoms” such as hot flashes, depression, panic attacks, cholesterol and other common symptoms associated with women entering menopause transition. The results suggest Pycnogenol® may serve as an alternative treatment to estrogen replacement therapy, which is the most common remedy of pre-menopause (“perimenopausal”) symptoms.
According to the U.S. Department of Health and Human Services, perimenopause is the natural part of aging that signals the ending of a woman’s reproductive years. It marks the time when a woman’s body begins its move into menopause and can last anywhere from two to eight years.
Do you remember exactly where you were when you learned of the Sept. 11 terrorist attacks? Your answer is probably yes, and researchers are beginning to understand why we remember events that carry negative emotional weight.
Boston College psychologist Elizabeth Kensinger and colleagues explain when emotion is likely to reduce our memory inconsistencies.
Her research shows that whether an event is pleasurable or aversive seems to be a critical determinant of the accuracy with which the event is remembered, with negative events being remembered in greater detail than positive ones.
A research team has discovered DNA from living bacteria that are more than half a million years old. This is the oldest example of a still-living organism. The discovery was made by Professor Eske Willerslev from the University of Copenhagen and his international research team.
All cells decompose with time but some cells are better than others at delay the aging process. Some organisms are capable of regenerating and thereby repairing damaged cells. These cells – their DNA – are important to the understanding of the process of how cells break down with age.
Hot spots across Southeastern Europe from 21 to 26 August have been detected with instruments aboard ESA satellites, which have been continuously surveying fires burning across the.
Working like thermometers in the sky, the Along Track Scanning Radiometer (ATSR) on ESA’s ERS-2 satellite and the Advanced Along Track Scanning Radiometer (AATSR) on ESA’s Envisat satellite measure thermal infrared radiation to take the temperature of Earth's land surfaces.
Haze of the smoke over Greece, covering in particular the area of Olympia.
Greenhouse gases likely accounted for over half of the widespread warmth across the continental United States in 2006, according to a new study in Geophysical Research Letters. Last year's average temperature was the second highest since recordkeeping began in 1895. The team found that it was very unlikely that the 2006 El Nino played any role, though other natural factors likely contributed to the near-record warmth.
When average annual temperature in the United States broke records in 1998, a powerful El Nino was affecting climate around the globe. Scientists widely attributed the unusual warmth in the United States to the influence of the ongoing El Nino. El Nino is a warming of the surface of the east tropical Pacific Ocean.
Female beetles mate to quench their thirst according to new research by a University of Exeter biologist. The males of some insect species, including certain types of beetles, moths and crickets, produce unusually large ejaculates, which in some cases can account for around 10% of their body weight. The study shows that dehydrated females can accept sexual invitations simply to get hold of the water in the seminal fluid.
Dr Martin Edvardsson, whose research is published in the journal Animal Behaviour (August 2007), studied the bruchid beetle Callosobruchus maculatus, a serious pest in warmer parts of the world. Some females were given unlimited access to water while others were not.
Researchers may be able to tinker with a single amino acid of an enzyme that helps viruses multiply to render them harmless, according to molecular biologists who say the discovery could pave the way for a fast and cheap method of making vaccines.
"We have successfully tested this technique with poliovirus," said Craig Cameron, the Paul Berg professor of biochemistry and molecular biology at Penn State. "And we think it is applicable to most other viruses."
Viruses have a simple mission; infect a cell, make more viruses, and then break out of the cell to infect more cells. This calls for fast and efficient multiplication. Viruses do this with the help of an enzyme called polymerase, whose main job is to assist in making more copies of the virus.
A study about predicting the outcome of actual conflicts found that the forecasts of experts are little better than those of novices, according to a new study.
When presented with actual crises, such as a disguised version of a 1970s border dispute between Iraq and Syria and an unfolding dispute between football players and management, experts were able to forecast the decisions the parties made in only 32% of the cases, little better than the 29% scored by undergraduate students. Chance guesses at the outcomes would be right 28% of the time.
Kesten C. Green of Monash University in Australia says, “Political leaders in the West are pondering how best to deal with the threat of the Iranian government’s nuclear ambitions.
Following are five myths about girls and science, according to the National Science Foundation.
1. Myth: From the time they start school, most girls are less interested in science than boys are.
Reality: In elementary school about as many girls as boys have positive attitudes toward science. A recent study of fourth graders showed that 66 percent of girls and 68 percent of boys reported liking science. But something else starts happening in elementary school. By second grade, when students (both boys and girls) are asked to draw a scientist, most portray a white male in a lab coat. The drawings generally show an isolated person with a beaker or test tube. Any woman scientist they draw looks severe and not very happy.
It turns out boyfriends really do try harder than husbands, according to a new study from George Mason University.
The study of more than 17,000 people in 28 countries found that married men report doing less housework than men who are live-in boyfriends. Still no word on whether or not married men also get less sex. Not that correlation equals causation.
This study was recently published in the Journal of Family Issues by Shannon Davis and co-authors Theodore Greenstein and Jennifer Gerteisen Marks of North Carolina State University.
Genetic markers contain pieces of foreign DNA that allow researchers to know when the gene they inserted into a cell has produced the desired trait, like glowing when exposed to ultraviolet light. This is important because results are not easy to see.
Whitehead Institute for Biomedical Research postdoctoral researchers Alexander Meissner and Marius Wernig have demonstrated that it’s possible to convert specialized mouse skin cells into unspecialized stem cells and have identified successfully reprogrammed cells by looks alone.
Their findings bring human stem cell therapies a step closer to reality.
