Skin and non-adhesive cells found to play pivotal role in formation of fingers

Thursday February 27th, 2020 09:05:56 PM
Human fingers are sculpted from a primitive pad-like structure during embryonic development. Sometimes, this process goes awry and babies are born with fused fingers or toes. A new study reveals new factors involved in the congenital malformation called syndactyly.

Polymers get caught up in love-hate chemistry of oil and water

Thursday February 27th, 2020 09:05:52 PM
Researchers have achieved a rare look at the inner workings of polymer self-assembly at an oil-water interface to advance materials for neuromorphic computing and bio-inspired technologies.

Thinning, prescribed burns protected forests during the massive Carlton Complex wildfire

Thursday February 27th, 2020 09:05:48 PM
In the first major study following the devastating 2014 Carlton Complex fire in north central Washington, researchers from the University of Washington and US Forest Service found that previous tree thinning and prescribed burns helped forests survive the fire.

Distrust of past experience may underlie obsessive-compulsive symptoms

Thursday February 27th, 2020 07:43:20 PM
People with higher obsessive-compulsive symptoms may place less trust in their past experience, leading to increased uncertainty, indecisiveness, and exploratory behaviors, according to new research.

Using a cappella to explain speech and music specialization

Thursday February 27th, 2020 07:43:17 PM
Speech and music are two fundamentally human activities that are decoded in different brain hemispheres. A new study used a unique approach to reveal why this specialization exists.

Environmental damage to coral reefs in South China Sea

Thursday February 27th, 2020 07:43:15 PM
New research reveals the unseen environmental damage being done to coral reefs in the hotly contested South China Sea, as China and other nations jostle for control of the disputed sea lanes.

How caloric restriction prevents negative effects of aging in cells

Thursday February 27th, 2020 07:42:59 PM
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 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.

How green space can reduce violent crime

Thursday February 27th, 2020 07:42:53 PM
Researchers identified patterns that can inform public policy, guide urban design and promote neighborhoods that are safe and low in crime.

How door-to-door canvassing slowed an epidemic

Thursday February 27th, 2020 07:42:51 PM
Liberia was the epicenter of a high-profile Ebola outbreak in 2014-15, which led to more than 10,000 deaths in West Africa. But for all the devastation the illness caused, it could have been worse without an innovative, volunteer-based outreach program Liberia's government deployed in late 2014. A study shows how much that program, consisting of door-to-door canvassing by community volunteers, spread valuable information and changed public practices during the epidemic.

Newly identified cellular trash removal program helps create new neurons

Thursday February 27th, 2020 07:42:45 PM
New research reveals how a cellular filament helps neural stem cells clear damaged and clumped proteins, an important step in eventually producing new neurons.

Sugar-poor diets wreak havoc on bumblebee queens' health

Thursday February 27th, 2020 07:42:41 PM
A new study shows that without adequate sugar, a bumblebee queen's fat body, which functions like a human liver, does not correctly produce enzymes required for healthy metabolism and detoxification from pesticides.

Big data helps farmers adapt to climate variability

Thursday February 27th, 2020 07:42:35 PM
A new study has precisely quantified soil and landscape features and spatial and temporal yield variations in response to climate variability.

A better way to detect underground water leaks

Thursday February 27th, 2020 07:42:33 PM
Researchers propose a new way to locate water leaks within the tangle of aging pipes found beneath many cities. The improvement could save time, money and billions of gallons of water.

Octopus-inspired robot can grip, move, and manipulate a wide range of objects

Thursday February 27th, 2020 07:42:22 PM
Researchers have developed an octopus-inspired soft robotic arm that can grip, move, and manipulate a wide range of objects. Its flexible, tapered design, complete with suction cups, gives the gripper a firm grasp on objects of all shapes, sizes and textures -- from eggs to iPhones to large exercise balls.

'Surfing attack' hacks Siri, Google with ultrasonic waves

Thursday February 27th, 2020 07:37:52 PM
Using ultrasound waves propagating through a solid surface, researchers were able to read text messages and make fraudulent calls on a cellphone sitting on a desk up to 30 feet away.

Genetic 'fingerprints' implicate gut bacterium in bowel cancer

Thursday February 27th, 2020 04:45:43 PM
A common type of bacteria found in our guts could contribute to bowel cancer, according to new research. Scientists 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.

A common gut microbe secretes a carcinogen

Thursday February 27th, 2020 04:45:40 PM
Cancer mutations can be caused by common gut bacteria. By exposing human mini-guts to a particular strain of Escherichia coli, scientist uncovered that these bacteria induce a unique mutational pattern in human DNA. This pattern was also found in colon cancer patients, implying that the bacteria induced these mutations. For the first time the researchers establish a direct link between microbes and mutations driving tumorigenesis. This might lead to new measures in colorectal cancer prevention.

SNIPRs take aim at disease-related mutations

Thursday February 27th, 2020 04:45:38 PM
Scientists describe a new method for detecting point mutations. The technique can be applied in living cells, offering a rapid, highly accurate and inexpensive means of identifying mutations relevant to human health.

A molecular atlas of skin cells

Thursday February 27th, 2020 04:45:36 PM
Our skin protects us from physical injury, radiation and microbes, and at the same time produces hair and facilitates perspiration. Details of how skin cells manage such disparate tasks have so far remained elusive. Now, researchers have systematically mapped skin cells and their genetic programs, creating a detailed molecular atlas of the skin in its complexity.

Huntington's disease-causing DNA repeat mutations reversed in the lab

Thursday February 27th, 2020 04:45:28 PM
An international team of researchers identifies a compound that corrects genetic abnormalities involved in the onset and progression of Huntington's disease for which there is no definitive treatment. They successfully reversed disease-causing DNA expansion mutations with no off-target effects in the lab. They hope that their discovery may help treat other DNA repeat diseases like myotonic dystrophy.
