HANOVER, N.H. - February 27, 2020 - Researchers have developed a process that could sharply reduce the work involved in computational protein design, according to a study in Proceedings of the National Academy of Sciences.

The technique uses 3D structural models to project how novel combinations of molecular blocks might work together to achieve a desired effect.

Ultrasonic waves don't make a sound, but they can still activate Siri on your cellphone and have it make calls, take images or read the contents of a text to a stranger. All without the phone owner's knowledge.

Attacks on cell phones aren't new, and researchers have previously shown that ultrasonic waves can be used to deliver a single command through the air.

Of all the cool things about octopuses (and there's a lot), their arms may rank among the coolest.

Two-thirds of an octopus's neurons are in its arms, meaning each arm literally has a mind of its own. Octopus arms can untie knots, open childproof bottles, and wrap around prey of any shape or size. The hundreds of suckers that cover their arms can form strong seals even on rough surfaces underwater.

Imagine if a robot could do all that.

A common type of bacteria found in our guts could contribute to bowel cancer, according to research funded by a £20 million Cancer Research UK Grand Challenge award and published in Nature today (Thursday)*.

Scientists in The Netherlands, the UK and USA have shown that a toxin released by a strain of E. coli causes unique patterns, or 'fingerprints', of DNA damage to the cells lining the gut.

HOUSTON -- A study at The University of Texas MD Anderson Cancer Center discovered a novel therapeutic vulnerability for patients who have tumors caused by a genetic misfire in the DNA mismatch repair (MMR) pathway, a system for repairing genetic aberrations. Study findings were published in the Feb. 27 online issue of Cancer Cell.

A typo appearing in the draft of a novel is no great calamity. Nature, however, is often less forgiving of errors. A change in just one letter of the genetic code can have catastrophic consequences for human health.

LA JOLLA--(February 27, 2020) If you want to reduce levels of inflammation throughout your body, delay the onset of age-related diseases, and live longer--eat less food. That's the conclusion of a new study by scientists from the US and China that provides the most detailed report to date of the cellular effects of a calorie-restricted diet in rats. While the benefits of caloric restriction have long been known, the new results show how this restriction can protect against aging in cellular pathways, as detailed in Cell on February 27, 2020.

Inland Antarctic ice contains volumes of water that can raise global sea levels by several metres. A new study published in the journal Nature shows that glacier ice walls are vital for the climate, as they prevent rising ocean temperatures and melting glacier ice.

The ocean can store much more heat than the atmosphere. The deep sea around Antarctica stores thermal energy that is the equivalent of heating the air above the continent by 400 degrees.

(Philadelphia, PA) - The same way baking soda breaks down grease and grime, making surfaces easier to clean, researchers at the Lewis Katz School of Medicine at Temple University (LKSOM) now show that a new therapeutic molecule can break apart communities of harmful bacteria, opening the way for bacteria-killing antibiotics to more effectively clear out infections.

Getting printer toner on your hands is annoying. Getting it in your lungs may be dangerous.

According to a new study by West Virginia University researcher Nancy Lan Guo, the microscopic toner nanoparticles that waft from laser printers may change our genetic and metabolic profiles in ways that make disease more likely. Her findings appear in the International Journal of Molecular Sciences.

A scientific team from the Biosciences and Biotechnology Institute of Aix-Marseille in Saint-Paul lez Durance, in collaboration with researchers from the Max Planck Institute of Colloids and Interfaces in Potsdam and the University of Göttingen, determined the trajectory and swimming speed of the magnetotactic bacterium Magnetococcus marinus, known to move rapidly. The actual speed is 400-500 μm/s for a 1 μm bacterium, making it a swimming champion. More surprisingly, the trajectory is made up of complex spirals.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo report the first occurrence of directly splitting one photon into three.

The occurrence, the first of its kind, used the spontaneous parametric down-conversion method (SPDC) in quantum optics and created what quantum optics researchers call a non-Gaussian state of light. A non-Gaussian state of light is considered a critical ingredient to gain a quantum advantage.

Instead of blocking hackers, a new cybersecurity defense approach developed by University of Texas at Dallas computer scientists actually welcomes them.

The method, called DEEP-Dig (DEcEPtion DIGging), ushers intruders into a decoy site so the computer can learn from hackers' tactics. The information is then used to train the computer to recognize and stop future attacks.

New research from the Canadian Longitudinal Study on Aging shows that adults who have low fruit and vegetable intakes have a higher likelihood of being diagnosed with an anxiety disorder.

"For those who consumed less than 3 sources of fruits and vegetables daily, there was at least at 24% higher odds of anxiety disorder diagnosis," says study lead Karen Davison, health science faculty member, nutrition informatics lab director at Kwantlen Polytechnic University, (KPU) and North American Primary Care Research Group Fellow.

The newly developed [55Co]55Co-DOTATATE imaging agent has emerged as a more accurate and sensitive radiopharmaceutical to aid in the diagnosis of neuroendocrine tumor metastases. According to research published in the February issue of the Journal of Nuclear Medicine, positron emission tomography/computed tomography (PET/CT) imaging with [55Co]Co-DOTATATE resulted in superior image contrast and enhanced detection of metastases as compared with other commonly used radiopharmaceuticals.
