    A new 3-D printed ‘sponge’ sops up excess chemo drugs

    Bringing the filtering abilities of a fuel cell into the blood vessels of living organisms, a new device could cut down on toxic effects of cancer treatment.

    At the heart of this approach — recently tested in pigs — is a tiny, cylindrical “sponge” created by 3-D printing. Wedged inside a vein near a tumor being treated with chemotherapy, the sponge could absorb excess drug before it...

    Desalination pours more toxic brine into the ocean than previously thought

    Technology meant to help solve the world’s growing water shortage is producing a salty environmental dilemma.

    Desalination facilities, which extract drinkable water from the ocean, discharge around 142 billion liters of extremely salty water called brine back into the environment every day, a study finds. That waste product of the desalination process can kill marine life and...

    A drill built for Mars is being used to bore into Antarctic bedrock

    Once destined for Mars, a prototype drill has a new mission: To bore into rocks buried deep beneath the ice in Antarctica.

    In early January, researchers from the University of Glasgow in Scotland took a modified version of their Martian drill to Antarctica. They’re poised to send it down to the bottom of a 651-meter deep ice borehole completed January 10 by researchers with the British...

    A new app tracks breathing to detect an opioid overdose

    A new smartphone app may help people who shoot up alone get medical treatment if they accidentally overdose.

    The app, dubbed Second Chance, monitors its user for breathing problems that foreshadow an opioid overdose (SN: 3/31/18, p. 18). In an emergency, the app could call 911 or send an SOS to friends or family who could provide opioid-counteracting medication.

    “Being able to...

    A new implant uses light to control overactive bladders

    A new soft, wireless implant may someday help people who suffer from overactive bladder get through the day with fewer bathroom breaks.

    The implant harnesses a technique for controlling cells with light, known as optogenetics, to regulate nerve cells in the bladder. In experiments in rats with medication-induced overactive bladders, the device alleviated animals’ frequent need to pee,...

    These sound waves can levitate and move particles in new ways

    A new machine uses ultrasonic waves to make particles dance in midair like marionettes on (invisible) strings.

    Unlike other devices that also use sound radiation to manipulate matter, the new system can move several objects in different directions at once (SN: 4/19/14, p. 8). This kind of levitation technology, described online the week of December 17 in Proceedings of the National...

    A new way to turn saltwater fresh can kill germs and avoid gunk buildup

    A new design for sun-powered desalination technology may lead to longer-lasting devices that produce cleaner water.

    The trick boils down to preventing a device’s components from touching the saltwater. Instead, a lid of light-absorbing material rests above a partially filled basin of water, absorbing sunlight and radiating that energy to the liquid below. That evaporates the water to...

    These new tweezers let scientists do biopsies on living cells

    It’s like the world’s smallest game of “Operation.” A new set of nanotweezers can extract DNA and other single molecules from a living cell without killing it.

    Examining the molecular contents of a single cell has traditionally required killing the cell by bursting it open. But that process provides only a single snapshot of the cell’s molecular makeup at the time of its death. The new...

    A patch studded with tiny needles may help heart attack survivors recover

    A new type of implantable bandage could help mend broken hearts.

    Each bandage is a thin film that oozes a cocktail of molecules to heal tissue damaged during a heart attack. In experiments with rats and pigs, these patches helped minimize scarring and preserve the heart’s ability to pump blood, researchers report online November 28 in Science Advances. Such devices could someday curb...
