Bacterial therapy in a dish

Recent research has found that many bacteria selectively colonize tumors in vivo, prompting scientists to engineer them as programmable vehicles, biological "robots" in other words, to deliver anticancer therapeutics. Researchers are also developing new, "smart" medicines by programming bacteria to tackle other diseases, such as gastrointestinal disease and infections. Key

Scientists build a machine to see all possible futures

"When we think about the future, we are confronted by a vast array of possibilities", explains Assistant Professor Mile Gu of NTU Singapore, who led development of the quantum algorithm that underpins the prototype "These possibilities grow exponentially as we go deeper into the future. For instance, even if we

Bacteria harness viruses to distinguish friend from foe

"This is the first evidence that cells can distinguish themselves from related competitors through the use of a virus," says Thomas Wood of Pennsylvania State University, one of the co-senior authors on the study. "The implications are that we should re-evaluate the relationship between a virus and its cellular host

Best in snow: New scientific device creates electricity from snowfall: The first-of-its-kind nanogenerator also acts as a weather station

"The device can work in remote areas because it provides its own power and does not need batteries," said senior author Richard Kaner, who holds UCLA's Dr.

New compound allows bacterial communication to be controlled by light

In order to respond to their environment, bacteria 'talk' to each other through a form of chemical communication called quorum sensing..

New species of early human found in the Philippines

Co-author and a lead member of the team, Professor Philip Piper from The Australian National University (ANU) says the findings represent a major breakthrough in our understanding of human evolution across Southeast Asia. The researchers uncovered the remains of at least two adults and one juvenile within the same archaeological

Crucial 'electrical switch' in brain: Native structure of AMPA receptor in rodent model may lead to discovering mechanism behind conditions such as Alzheimer's disease

The new research, published in the journal Science, is the first to reveal the structure of AMPA receptors in their natural state.

Ice Ages occur when tropical islands and continents collide: Collisions in tropics expose rocks that take up carbon dioxide, cooling normally balmy Earth

The key trigger, they say, is mountain formation in the tropics as continental land masses collide with volcanic island arcs, such as the Aleutian Islands chain in Alaska.

Off-the-shelf smart fabric helps athletic coaching and physical therapy: Merging low cost and high performance in body motion sensing

The proposed fabric-sensing system is a flexible, motion-capture textile that monitors joint rotation..

Woolly mammoths and Neanderthals may have shared genetic traits: Findings point to molecular resemblance in climate adaptation traits of the two species

The research attributes the human-elephant relationship during the Pleistocene epoch to their mutual ecology and shared living environments, in addition to other possible interactions between the two species. The study was led by Prof. Ran Barkai and Meidad Kislev of TAU's Department of Archaeology and Ancient Near Eastern Cultures and

Five-minute sample processing enhances DNA imaging and analysis

Described in ACS Nano, JILA's gentle, yet effective process involves binding DNA to mica, a flat silicate mineral.

Researchers remove harmful hormones from Las Vegas wastewater using green algae

EDCs are natural hormones and can also be found in many plastics and pharmaceuticals..

Cold plasma can kill 99.9% of airborne viruses

They hope to one day harness this capability to replace a century-old device: the surgical mask..

Slug glue reveals clues for making better medical adhesives: Findings could lead to suture alternatives that are flexible and strong

Typical sutures like staples and stitches often lead to scarring and create holes in the skin that could increase the chance of infection after surgeryz Rebecca Falconer Rebecca Falconer, who conducted one of the studies. "Understanding the roles of adhesive proteins in the slug glue would aid in the creation

Laying the ground for robotic strategies in environmental protection

With this motivation, a team of roboticists at Harvard's Wyss Institute for Biologically Inspired Engineering has developed a robot that can autonomously drive interlocking steel sheet piles into soil. The structures that it builds could function as retaining walls or check dams for erosion control. The study will be presented
