Experimental battery uses bacteria to charge and recharge

Experimental battery uses bacteria to charge and recharge A group of researchers from The Netherlands has devised a new biological battery that charges and discharges with the aid of bacteria.They’ve tested this system on the small scale and managed 15 charge cycles in a row.

How MIT’s new biological ‘computer’ works, and what it could do in the future

How MIT’s new biological ‘computer’ works, and what it could do in the future With a fully realized ability to program cell behavior as reliably as we do computer behavior, there’s no telling what biological computing could accomplish.In 2013, this same team designed the computing strain that preceded this one: a biological “state machine.

NASA’s new DNA sequencer on the ISS could be used on aliens

NASA’s new DNA sequencer on the ISS could be used on aliens The regular resupply missions to the International Space Station include the basics like food, but all sorts of new science toys as well.In the Dragon capsule that docked with the station several days ago, there was one particularly interesting device — a DNA sequencer.

Drug-resistant bacteria tricked into dropping their shields become vulnerable once again

Drug-resistant bacteria tricked into dropping their shields become vulnerable once again In search of another way to manage the endless slog against antibiotic-resistant bacteria, scientists just figured out how to bait bacteria into developing an Achilles’ heel.Not all drug resistance works the same: It depends on the type of antibiotic the bacteria have evolved to resist.

Deep-dwelling bacteria could rewrite our understanding of where alien life could take hold

Deep-dwelling bacteria could rewrite our understanding of where alien life could take hold Finding bacteria in extreme environments, like at thermal ocean vents or in the sulfur pools at Yellowstone, isn’t all that novel.In 1991, remote-control robots brought out samples of pitch-black fungi that had been growing inside the ruins of the Chernobyl reactor.

Genetic Sudoku is here, and it vastly speeds genomic analysis

Genetic Sudoku is here, and it vastly speeds genomic analysis The innovation has to do with one of the most powerful techniques in genetic analysis: whole genome knockout collections.Expose enough bacteria and you can be assured that you’ve got a mutation into every gene in an organism.

DNA evidence shows the Soviets covered up an anthrax accident that killed dozens

DNA evidence shows the Soviets covered up an anthrax accident that killed dozens Now, long after the true cause of the outbreak was revealed, scientists have been able to perform DNA analysis on the deadly bacterial strain.From viewing the original materials, Meselson’s team knew without a doubt they were looking at inhalation anthrax, not ingestion anthrax as the Russians originally claimed.

Researchers create a tiny tractor beam that totes bacteria around

Researchers create a tiny tractor beam that totes bacteria around “The principle underlying this laser beam is similar to the concept to be found in the television series Star Trek,” says Dr.In their new method, the Bielefeld researchers use a second laser beam as a single-cell optical trap — in other words, a tiny tractor beam — so that the cells float under the microscope and can be moved at will.

Powerhouse bacteria decontaminates wastewater and makes energy

Powerhouse bacteria decontaminates wastewater and makes energy For years, scientists have known Shewanella oneidensis isn’t your average bacteria.When the bacteria metabolizes heavy metals in an anaerobic (oxygen-free) environment, it uses current-conducting proteins to generate energy.

Here are the world's 12 scariest drug-resistant superbugs

Here are the world's 12 scariest drug-resistant superbugs In a world awash in antibiotics, dangerous infections are getting even harder to fight.The first-of-its-kind list is meant to steer public and private research dollars toward developing new antibiotics for these particular families of bacteria, the World Health Organization (WHO) said.

New research suggests that we can kill bacteria with some blue or purple light

New research suggests that we can kill bacteria with some blue or purple light But there is new research that suggests that certain visible light, namely violet light, could kill the salmonella bacteria in your refrigerator, rendering the contents of your fridge safer for consumption.In a new report in the American Council on Science and Health, scientists from Singapore have applied violet light for fridge-disinfecting purposes.

Antimicrobials may do more harm than good, report suggests

Antimicrobials may do more harm than good, report suggests A new report suggests that the “antimicrobial” ingredients found in everything from soaps to countertops, may not actually help keep us healthy.An antimicrobial is any agent that kills or inhibits the growth of microorganisms like bacteria.

Scientists figure out a way to 3D print materials like graphene using bacteria

Scientists figure out a way to 3D print materials like graphene using bacteria How about the possibility of printing custom materials such as graphene by using 3D-printed bacteria?They’ve developed a new process — thought to be a world first — that enables them to 3D print a range of materials using bacteria.

Harvard chemists design a ‘bionic leaf’ that can make its own fertilizer

Harvard chemists design a ‘bionic leaf’ that can make its own fertilizer “When you have a large centralized process and a massive infrastructure, you can easily make and deliver fertilizer,” Nocera said in a press release.Last June, he announced the “bionic leaf 2.

Scientists wants this CRISPR pill to one day replace antibiotics

Scientists wants this CRISPR pill to one day replace antibiotics Their weapons of choice are deception and a powerful gene-editing tool called CRISPR.Initially borrowed from bacteria, which use CRISPR as an immune defense against viruses, the gene-editing tool works by recording snippets of the attacker’s DNA, so that the bacteria can recognize and eliminate future invaders.

Only a superweapon can kill superbacteria, and humanity finally found it

Only a superweapon can kill superbacteria, and humanity finally found it For an antibiotic to work effectively, it must kill bacteria cells without destroying human cells, so biologists engineer antibiotics to target aspects unique to bacteria cells.For example, penicillin prevents the peptidoglycan in bacteria cells from linking, leaving the cell walls weak and prone to collapse.
