Changes in the brain caused by Alzheimer's disease are associated with shortening of the telomeres -- the protective caps on the ends of chromosomes that shorten as cells age -- according to a new study.
If you live near a busy road you might feel like the constant sound of roaring engines, honking horns and wailing sirens makes your blood pressure rise. Now a new study confirms it can do exactly that.
Researchers have developed a new type of neural implant that could restore limb function to amputees and others who have lost the use of their arms or legs. In a study carried out in rats, researchers from the University of Cambridge used the device to improve the connection between the brain and paralysed limbs. The device combines flexible electronics and human stem cells -- the body's...
Is nitrate responsible for algae, flowers, and even your neighbors? A team of geoscientists have unearthed evidence that may indicate yes.
Researchers have demonstrated a caterpillar-like soft robot that can move forward, backward and dip under narrow spaces. The caterpillar-bot's movement is driven by a novel pattern of silver nanowires that use heat to control the way the robot bends, allowing users to steer the robot in either direction.
Mutations in genes that form the desmosome are the most common cause of the cardiac disease arrhythmogenic cardiomyopathy (ACM), which affects one in 2000 to 5000 people worldwide. Researchers have now discovered how a mutation in the desmosomal gene plakophilin-2 leads to ACM. They found that the structural and functional changes in ACM hearts caused by a plakophilin-2 mutation are the result of...
As a way to reduce seed counterfeiting, researchers developed a silk-based tag that, when applied to seeds, provides a unique code that cannot be duplicated.
A new multidisciplinary study opens an exciting non-invasive therapeutic avenue for healing muscle injuries in elderly patients. Using a robotic mechanotherapy device on aged muscle, the researchers found that the same treatment that helps young muscle heal faster after injury actually has the opposite effect with aging -- it exacerbated the injury. After pinpointing mechanotherapy-induced...
Scientists have developed fully biodegradable, high-performance artificial muscles. Their research project marks another step towards green technology becoming a lasting trend in the field of soft robotics.
It is well known that the microbiomes of athletes are different from of those who are sedentary. To investigate how exercise shapes the gut microbiota in non-athletes, the study assessed information on the type, time and intensity of exercise in relation to microbiomes in a large cohort of middle-aged adults.
Memory B cells play a critical role to provide long-term immunity after a vaccination or infection. Researchers have now described a distinct and novel subset of memory B cells that predict long-lived antibody responses to influenza vaccination in humans. These effector memory B cells appear to be poised for a rapid serum antibody response upon secondary challenge one year later.
Chemical and isotopic analysis of artifacts from southern Africa called copper ingots reveals new cultural connections among people living in the region between the 5th and 20th centuries.
When resources are scarce, most animals have to choose. A new study reveals an ancient origin to how female butterflies invest.
By combining lab experiments and mathematical modelling, researchers have found a way to predict the movement of species that could guide conservation efforts to reconnect fragmented habitats.
Scientists have gained new insights into the part of the brain that gives us a sense of direction, by tracking neural activity with the latest advances in brain imaging techniques. The findings shed light on how the brain orients itself in changing environments -- and even the processes that can go wrong with degenerative diseases like dementia, that leave people feeling lost and confused.
People who have low bone density may have an increased risk of developing dementia compared to people who have higher bone density. The study does not prove that low bone density causes dementia. It only shows an association.
For mosquito-borne diseases such as dengue fever, the abundance of the insects in places where people gather has long served as the main barometer for infection risk. A new study, however, suggests that the number of 'hidden' infections tied to a place, or cases of infected people who show no symptoms, is the key indicator for dengue risk.
Researchers have developed a handheld sensor that tests perspiration for cortisol and provides results in eight minutes, a key advance in monitoring a hormone whose levels are a marker for many illnesses including various cancers.
