Using everyday WiFi to help robots see and navigate better indoors

Using everyday WiFi to help robots see and navigate better indoors

Engineers have developed a low cost, low power technology to help robots accurately map their way indoors, even in poor lighting and without recognizable landmarks or features. The technology uses WiFi signals, instead of light, to help the robot ‘see’ where it’s going. …read more

Scientists devise method to prevent deadly hospital infections without antibiotics

Scientists devise method to prevent deadly hospital infections without antibiotics

Some 1.7 million Americans each year acquire hospital infections, resulting in nearly 100,000 deaths from infection-related complications. The biggest culprits: medical devices like catheters, stents and heart valves, whose surfaces often become covered with harmful bacterial films. A novel surface treatment developed by a UCLA-led team of scientists stops microbes from adhering to medical devices. The new findings are published May 19 in the journal Advanced Materials. …read more

Lost or extinct? Study finds the existence of more than 500 animal species remains uncertain

Lost or extinct? Study finds the existence of more than 500 animal species remains uncertain

An international study provides the first global evaluation of all terrestrial vertebrate species that have not been declared extinct and identifies more than 500 species considered to be ‘lost’–those that haven’t been seen by anyone in more than 50 years. …read more

Epilepsy drug stops nervous system tumor growth in mice

Epilepsy drug stops nervous system tumor growth in mice

People with neurofibromatosis type 1 (NF1) develop tumors on nerves throughout their bodies. Researchers have discovered that nerve cells with the mutation that causes NF1 are hyperexcitable and that suppressing this hyperactivity with the epilepsy drug lamotrigine stops tumor growth in mice. …read more

Scientist uncovers clues to aging in mitochondria

Scientist uncovers clues to aging in mitochondria

Many age-related diseases share a common feature: the mitochondria of cells begin to malfunction. While the cause is not known, scientists have discovered a new mechanism of how mitochondria start to go wrong, which opens new doors for researchers to explore how to begin to fix the problem. …read more

Study reveals imaging approach with potential to detect lung cancer earlier, at the cellular level

Study reveals imaging approach with potential to detect lung cancer earlier, at the cellular level

Researchers have found a way to identify lung cancer at the cellular level in real time during a biopsy, offering promise in the ability to detect the disease earlier and with more confidence. …read more

Scientists develop and monitor two approaches to fix blood vessel abnormalities that make tumors difficult to treat

Scientists develop and monitor two approaches to fix blood vessel abnormalities that make tumors difficult to treat

Abnormal tumor blood vessels promote cancer progression and treatment resistance. Researchers have developed two approaches to repair tumor blood vessels and they have devised a method to measure the effects of these approaches. Combining the approaches may be an effective strategy for fixing blood vessel abnormalities that make tumors difficult to treat. …read more

Brain capital: A new investment approach for late-life well-being

Brain capital: A new investment approach for late-life well-being

Within many societies and cultures around the world, older adults are too often undervalued and underappreciated, according to a new article. This exacerbates many key challenges that older adults may face. It also undermines the many positive aspects of late life that are of value at both an individual and societal level. In the article, ‘Investing in Late-Life Brain Capital,’ a global team of experts propose a new approach to elevate health and well-being by optimizing late-life brain capital. …read more
