Some people love spicy food — the hotter, the better. Others go out of their way to avoid the palate-singeing burn of capsaicin, the compound that gives chili peppers their kick. Now, researchers have developed a portable device (whimsically shaped like a chili pepper) that can reveal how much capsaicin a pepper contains, before biting […]

Americans strongly reduced their visits to grocery stores, pharmacies, and transit stations following stay-at-home orders from mayors and governors earlier this year, but did not reduce their visits to parks and beaches. Source: Americans' responses to COVID-19 stay-home orders differed according to population density

A team of researchers has found that transcription factors have a tendency to bind strongly to ‘mismatched’ sections of DNA, i.e. sections of the genome that were not copied correctly. The strong binding of transcription factors to these mismatched sections of regulatory DNA might be a way in which random mutations become a problem that […]

Babies born with a faulty maternal copy of the UBE3A gene will develop Angelman syndrome, a severe neurodevelopmental disorder with no cure and limited treatments. Now, for the first time, scientists show that gene editing and gene therapy techniques can be used to restore UBE3A in human neuron cultures and treat deficits in an animal […]

New research shows a simple skin test can accurately identify Parkinson’s disease, which could lead to earlier detection of the disease and better outcomes for patients. Currently, Parkinson’s disease is diagnosed by clinical signs and symptoms but only definitively diagnosed at autopsy. The researchers conducted a blinded study of 50 skin samples using an assay […]

A peace sign from Martin Luther King, Jr, becomes a rude gesture; dolphins in Venice’s Grand Canal – manipulated or mis-used images posted as truth. Researchers say image editing software is so common and easy to use, it has the power to re-imagine history. Even the White House is doing it and deadline-driven journalists lack […]

Imagine a mobile phone charger that doesn’t need a wireless or mains power source. Or a pacemaker with inbuilt organic energy sources within the human body. Researchers are picking up the challenge of ‘scavenging’ invisible power from low-frequency vibrations in the surrounding environment, including wind, air or even contact-separation energy (static electricity).

A recent study shows that cold ambient temperatures increase vitamin A levels in humans and mice. This helps convert ‘bad’ white adipose tissue into ‘good’ brown adipose tissue which stimulates fat burning and heat generation. Source: Vitamin A boosts fat burning in cold conditions

Research has revealed that Virtual Reality (VR) technology can have significant impact on the validity of remote health appointments for those with eating disorders, through a process called Virtual Reality Exposure Therapy (VRET).

We employ our cognitive skills daily to assimilate and process information. A new empirical study shows that we do better at this task than those born a century ago. But cognitive capacity still begins to stagnate at around the age of 35. Source: Cognitive performance – Better than our predecessors
