New species of wood-munching clams found at the bottom of the ocean
Wood-boring clams are tiny clams that eat (and live in) sunken wood at the bottom of the ocean, and they have long, tube-shaped organs that they use to breathe called siphons sticking out of their shells. Scientists have just updated the wood-boring clam family tree, adding a new species and three new genus groups.

But place them under an ordinary optical microscope to reveal their crystalline structure, and you see what looks…

Host-guest complexation-mediated codelivery of anticancer drug and photosensitizer for cancer photochemotherapy [Chemistry]
Although platinum-based anticancer drugs prevail in cancer treatment, their clinical applications are limited by the severe side effects as well as their ineffectiveness against drug resistant cancers. A precise combination of photodynamic therapy (PDT) and chemotherapy can synergistically improve the therapeutic outcome and thereby may overcome drug resistance through a…

Recently, researchers studied a group of adults aged 70 or older who had advanced cancer (as well as other challenges). Results from the study were published in the Journal of the American Geriatrics Society.

Traditional surgery to reshape a nose or ear entails cutting and suturing, sometimes followed by long recovery times and scars. But now, researchers have developed a "molecular surgery" process that uses tiny needles, electric current and 3-D-printed molds to quickly reshape living tissue with no incisions, scarring or recovery time. The technique even shows promise as a way to fix immobile joints

Nature has evolved protein-based substances with mechanical properties that rival even the best synthetic materials. Pound for pound, spider silk is stronger and tougher than steel. But unlike steel, the natural fiber cannot be mass-produced. Today, scientists report a method in which bacteria produce spider silk and other proteins that could be useful during space missions.

'Molecular surgery' reshapes living tissue with electricity but no incisions
Traditional surgery to reshape a nose or ear entails cutting, sometimes followed by long recovery times and scars. Now, researchers have developed a 'molecular surgery' process using tiny needles, electric current and 3D molds to quickly reshape living tissue with no incisions, scarring or recovery time. It shows promise as a noninvasive alternative to laser eye surgery.

Snarkning hindrar kroppen från att läka skador i svalget
– Snarkning är inte bara störande utan också en påtaglig riskfaktor för hälsan. Men vi hyser gott hopp om att skadorna ska gå att förebygga och på sikt också att reparera, säger docent Per Stål, gruppens forskningsledare vid Institutionen för integrativ medicinsk biologi vid Umeå universitet. Forskarna i Umeå har sett att snarkare har skador på nerver och muskler i övre luftvägarna. Skadorna kan

Acute flaccid myelitis requires galvanized research response
Acute flaccid myelitis (AFM) presents significant challenges not only to patients but also to researchers, and efforts must be accelerated to learn more about the condition, experts from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, write in a new perspective published in mBio.

Will John Roberts Block the Triumph of Legal Conservatism?
Last year, as Americans prepared to celebrate Thanksgiving, John G.

Lessons of the Real Resistance
It is one thing to read about a tortured man in a cell.

Knowing how to behave in the #MeToo era
In the #MeToo era, many men feel they're walking on eggshells and can't say anything anymore. Companies must refocus their policies away from 1,000 page "don't do this" manuals and address the gray areas that are most confusing, like: Can you give a colleague a compliment? Workplace harassment training should focus on the principle that sexual harassment is about impact of your words or actions;

Nytt material ger flexibel, superkänslig värmesensor
Den superkänsliga värmesensorn bygger på det faktum att vissa material är termoelektriska. Att ett material är termoelektriskt betyder att en temperaturskillnad mellan två sidor av materialet får elektroner att röra sig från den kalla sidan mot den varma och en spänning uppstår. Dock har forskarna i det här fallet fått fram ett termoelektriskt material som leder joner istället för elektroner och

To Boost Brainpower, Ancient Hominins Sought Fat Before Meat
The prevailing theory among anthropologists is that flaked tool use and meat consumption led to the cerebral expansion that kickstarted human evolution more than 2 million years ago. But new research posits earlier hominins may have first scavenged bones to harvest fatty nutrients from marrow and brains.

Hands spread flame retardants, plasticizers throughout homes
