Detection

  • When hospitals are checking medical devices for sepsis, they utilize a chemical derived from horseshoe crab blood. A new system is promised to deliver a more sustainable supply of that blood, which could even be used to check human blood for sepsis.
  • A compelling new study from the International Agency for Research on Cancer is suggesting a simple biomarker in urine may be an effective test for bladder cancer, signaling the disease's presence up to 10 years before clinical signs appear.
  • If someone is showing symptoms that may be caused by a toxic algae bloom, it's important to know ASAP if that is indeed the culprit. A new urine test could soon help in doing so.
  • Ordinarily, when biological samples are being tested to see which (if any) viruses are present, it can take up to several days to get results. An inexpensive new tool, however, is claimed to capture and identify viruses within minutes.
  • Improvised Explosive Devices (IEDs) can be difficult for soldiers to detect, as they're made in a variety of shapes and sizes, and are typically buried in the road. A new vehicle-mounted system, however, is designed to "spot the signs" of IEDs.
  • MIT engineers have developed a system that looks at shadows on the ground to help autonomous vehicles avoid collisions with objects like cars or pedestrians appearing from around corners or behind buildings.
  • Ordinarily, if it's suspected that toxic airborne chemicals may be present in a given area, the analysis process can take several days. Now, however, scientists have developed a device that they claim can analyze the air within 10 seconds.
  • Presently, in order to check the level of opioid drugs in a person's bloodstream, a blood sample must be taken. Things may soon be getting much less invasive, however, as scientists have now developed a breath test that does the job.
  • Although ice formation on the wings is a major cause of aircraft crashes, that ice must still mainly be spotted by eye. A new sensor could change that, however, as it uses microwaves to instantly detect the formation of ice that may not be visible to pilots or ground crews.
  • ​Ordinarily, when drinking water is being tested for toxic heavy metals, samples have to be sent off to labs. And while there are portable testing systems, they do have some limitations. A new device, however, is claimed to work better – by copying a process that takes place within the human body.
  • Science
    ​While there are already electronic devices that detect toxic gases, they can be expensive, and require training to properly use. Soon, though, there could be a cheap and simple alternative – threads woven into washable clothing, that change color when nasty gases are present.
  • Science
    ​Although a certain amount of fluoride is added to municipal water supplies to help prevent tooth decay, too much can actually have the opposite effect – particularly on children. A new device could allow officials to detect those overly-high levels, cheaper and easier than ever before.
