Researchers discover a method that can potentially block tumor growth in animal subjects with cancer

In an exciting new development, scientists from the University of Pennsylvania’s Perelman School of Medicine have found what they term the Achilles’ Heel of cancerous tumors. According to a study published in Nature Cell Biology, activating transcription factor 4 (ATF4) could be the key to conquering cancer. While millions of our body’s cells essentially commit […]

Scientists develop home-testing kit that measures stress hormones

Stress can either be a person’s boon or his bane, depending on the situation. In certain situations, it can motivate people, but those with chronic levels of stress are more likely to develop health problems, including heart disease and even mental disorders. To combat its adverse effects, researchers have developed a simple test to help […]

From poison to cure: Researchers synthesize scorpion venom compounds to fight “highly infectious bacteria”

Scorpion venom might hold the key to eliminating some strains of highly infectious bacteria, a recent study shows. According to a paper published in the journal Proceedings of the National Academy of Sciences, scientists from Stanford University and the National Autonomous University of Mexico (UNAM) discovered that two compounds from the venom of an Eastern Mexican […]

Study: Light and nanotech can prevent bacterial infections caused by medical implant surgeries

Spanish researchers combined nanotechnology and photonics to improve the effectiveness of medical meshes in surgical implants. Powered by light, nanoparticles killed any disease-causing bacteria that might cause a dangerous infection in the mesh. Medical meshes help a surgery patient recover faster after an operation that removed, repaired or replaced damaged tissue in his body. A […]

Scientists discover “electric” bacteria – can it lead to next-gen batteries and miniature pacemakers?

Experts know that a strange species of bacteria found in oxygen-deprived sediment and soil can generate electricity. But they only recently learned that the microorganism achieves this through a method that differs from that used by other electric bacteria. Called Geobacter sulfurreducens, the anaerobic bacteria possess a unique biological structure. This previously unidentified feature makes it possible […]

Sniffing out cancer: Researchers say canine scent detection can be used as an effective cancer screening method

We’ve all heard stories of heroic dogs saving people’s lives, whether they alerted their sleeping owners to a fire in time for them to escape or they found people who were trapped in disaster areas. However, there’s a growing body of evidence that their life-saving abilities go a lot further than that: They can also […]

Electric bandages? Researchers say they heal wounds better, faster than antibiotics

Bandages that generate electricity have been used for a while to speed up wound healing. However, the mechanism that enables these electrical bandages to work the way they do has not been fully understood – until recently. Researchers from Ohio State University (OSU) found new clues on how they work, which could result in better wound […]

Deadly blow to the chest does not affect heart contraction, according to research

Why do healthy baseball players die when a ball slams into their chest while patients survive potentially lethal tachyarrhythmia attacks when they get a timely thump to the chest? Swiss researchers hoped to answer this puzzle with a recently-developed instrument that simulates how a blow to the chest affects the heart rate. When the chest receives […]

Study: Can nanoparticles be used to deliver treatments to injured brain and spinal cord cells?

A research team from Purdue University has designed a cutting-edge treatment that could quickly repair brain and spinal cord cells that have been injured. The treatment method enlists medicated nanoparticles to the injury site, preventing secondary damage to the spine, restoring cellular function, and improving physiological processes. The researchers achieved great results when they tested […]

Life threatening risk: Hackers can take over defibrillators, rewrite commands with disastrous consequences – DHS warning

The Department of Homeland Security is warning against a critical flaw in Medtronic defibrillators which can be hacked by malicious actors. If a hacker were to exploit this flaw, they could gain control of the machine and rewrite commands — actions which could have fatal consequences. At the time of this reporting, there have been […]
