We notice a voice much faster when it is considered threatening than when it is perceived as normal or happy. Our attention is more focused on threatening voices to enable us to clearly recognize the location of the potential threat.
Social status determined how individual macaques responded to a key stress hormone, glucocorticoid.
The potentially fatal effects of blows to the chest are believed to be the result of rapid strains that adversely interfere with the transmission of electrical impulses thereby causing disruption of the heartbeat. The same interactions are thought to underlie the rescue of patients in cardiac arrest by an appropriately timed thump to the chest.
Repeated exposure to the acute effects of exercise may contribute to the fight against cancer. Exercise may play a role in inhibiting the growth of colon cancer cells. After an acute bout of HIIT there were specific increases in inflammation immediately after exercise, which are hypothesised to be involved in reducing the number of cancer cells.
Humans have a ''disproportionately huge effect'' on the other species of vertebrates that share Earth's surface with us, causing more than 25 percent of the deaths among an array of species all over the globe, according to a recently published study.
The decision to have a child is primarily an emotional one and often in India, a cultural pressure to which most people succumb. But as resources are being stretched to breaking point, it is evident that the uncomfortable truth associated with overpopulation is crossing people’s minds and motivating some to not contribute further to the problems. A study published in Environmental Research Letters equates the impact of having one fewer child to reducing 58 metric tonnes of CO2 for each year of the parent’s life. Other helpful ways to reduce one’s carbon footprint pale in comparison. Going car-free saves emissions by 2.4 metric tonnes and eating a plant-based diet 0.82 metric tonnes.
Today, Bad Kissingen has rebranded itself as the world’s first ChronoCity – a place where internal time is as important as external time, and sleep is sacrosanct.
Capsaicin has been shown to alter the expression of several genes involved in cancer cell survival, growth arrest, angiogenesis and metastasis. Recently, many research groups have found that capsaicin targets multiple signaling pathways, oncogenes and tumor-suppressor genes in various types of cancer models. Capsaicin has been shown to induce apoptosis in many different types of cancer cell lines while leaving normal cells unharmed.
More than half of cancer survivors suffer from cognitive impairment from chemotherapy that lingers for months or years after the cancer is gone.
Study shows that higher levels of vitamin D are associated with better exercise capacity.
Research provides the first evidence that magnesium may play an important role in optimizing vitamin D levels and preventing conditions related to vitamin D levels.
Certain treatments, including radiation and some chemotherapeutic drugs, work by damaging the DNA of cancer cells, but they can also cause damage to DNA of normal cells, which can contribute to accelerated biological aging.
There is growing evidence that cancers can go backward or stop, and researchers are being forced to reassess their notions of what cancer is and how it develops.
A project funded by a research agency of the US Department of Defense is now giving rise to concerns about being possibly misused for the purpose of biological warfare. The programme called 'Insect Allies' intends for insects to be used for dispersing genetically modified viruses to agricultural plants in fields.
Review authors found that psychological well-being influenced heart health through biological processes, health behaviors and psychosocial resources.
The flower-based chemical compounds that are the basis for the perfumes and colognes we use today have been providing olfactory excitement to pollinating insects and other animals since the mid-Cretaceous Period.
The immune system can stop the growth of a cancerous tumor without actually killing it. The study's authors call the cancer-immune system stalemate equilibrium. During equilibrium, the immune system both decreases the cancer's drive to replicate and kills some of the cancerous cells, but not quickly enough to eliminate or shrink the tumor.
With hindered memory maintenance, it's much more difficult to pick up a task where you left off without missteps.
Children who grow up in poverty or who are otherwise socially and economically disadvantaged may be more likely in old age to score lower than others on tests of cognitive skills, according to a study.
The body has evolved anti-cancer responses that direct and slow the evolution of life-threatening cancer cells by not killing off too many cells too quickly. Natural adaptive therapies would use a similar approach to keep tumor size stable, while slowing the evolution of resistance. This strategy may be especially useful to prolong lifespan and quality of life in patients after a cancer has metastasized.
