Ageing can drive progress

The UN estimates that the number of people aged 65 and older will have reached almost a billion by 2030. The proportion of those aged over 80 will grow at particularly high rates, and their numbers are expected to reach 200 million by...Show More Summary

China experiment of the day

Chinese scientists are on the verge of being first in the world to inject people with cells modified using the CRISPR–Cas9 gene-editing technique. A team led by Lu You, an oncologist at Sichuan University’s West China Hospital in Chengdu, plans to start testing such cells in people with lung cancer next month. Show More Summary

Texans are no better off in one city versus another for cancer treatment

HOUSTON - (July 25, 2016) - Regions in Texas differ widely in adherence to recommended cancer treatment for elderly patients, according to a study by researchers at Rice University and the University of Texas MD Anderson Cancer Center. These...Show More Summary

Digging deeper into Mars

Water is the key to life on Earth. Scientists continue to unravel the mystery of life on Mars by investigating evidence of water in the planet's soil. Previous observations of soil observed along crater slopes on Mars showed a significant amount of perchlorate salts, which tend to be associated with brines with a moderate pH level.

Spiders spin unique phononic material

HOUSTON - (July 25, 2016) - New discoveries about spider silk could inspire novel materials to manipulate sound and heat in the same way semiconducting circuits manipulate electrons, according to scientists at Rice University, in Europe...Show More Summary

DNA sequencing uncovers latent risk for developing cystic fibrosis

A study by researchers at Children's Hospital Los Angeles (CHLA), Brigham and Women's Hospital and the California Department of Public Health suggests that all babies with a known mutation for cystic fibrosis (CF) and second mutation called the 5T allele should receive additional screening in order to better predict the risk of developing CF later in life. read more

WSU researchers 'watch' crystal structure change in real time

PULLMAN, Wash.--Washington State University researchers have met the long-standing scientific challenge of watching a material change its crystal structure in real time. While exposing a sample of silicon to intense pressure--due toShow More Summary

Astronomers discover dizzying spin of the Milky Way galaxy's 'halo'

Astronomers at the University of Michigan's College of Literature, Science, and the Arts (LSA) discovered for the first time that the hot gas in the halo of the Milky Way galaxy is spinning in the same direction and at comparable speed as the galaxy's disk, which contains our stars, planets, gas, and dust.

New nontoxic process promises larger ultrathin sheets of 2-D nanomaterials

OAK RIDGE, Tenn., July 25, 2016 - A team of scientists led by the Department of Energy's Oak Ridge National Laboratory has developed a novel way to produce two-dimensional nanosheets by separating bulk materials with nontoxic liquid nitrogen. Show More Summary

Bio-engineered molecule shows promise for quick control of bleeding

Every five minutes someone in the U.S. dies from a blood clot, through its role in strokes, heart attacks or other severe conditions. For decades, doctors have used the anticoagulant drug warfarin (Coumadin) to prevent clots. More recently,...Show More Summary

Among the oldest adults, poor balance may signal higher risk for dementia

The number of people living well into their 90s is projected to quadruple by 2050. By mid-century, nearly 9 million people will be 90-years-old or older. In a first-of-its-kind study published in the Journal of the American Geriatrics...Show More Summary

Enhancing molecular imaging with light

In 2014, an international trio won the Nobel Prize in Chemistry for developing super-resolution fluorescence microscopy, a technique that made it possible to study molecular processes in living cells. Now a Northwestern Engineering team has improved this groundbreaking technology by making it faster, simpler, less expensive, and increasing its resolution by four fold. read more

Predicting the risk for developing pneumonia in older adults

In a study published in the Journal of American Geriatrics Society, researchers developed a "prediction score" to help healthcare professionals determine which older adults might be most at risk for developing pneumonia. Pneumonia is a leading cause of sickness and death among older adults. Show More Summary

Penn researchers develop placenta-on-a-chip

Researchers at the University of Pennsylvania have developed the first placenta-on-a-chip that can fully model the transport of nutrients across the placental barrier. The flash-drive-sized device contains two layers of human cells that model the interface between mother and fetus. Show More Summary

Embryonic gene Nanog reverses aging in adult stem cells

BUFFALO, N.Y. -- The fountain of youth may reside in an embryonic stem cell gene named Nanog. In a series of experiments at the University at Buffalo, the gene kicked into action dormant cellular processes that are key to preventingShow More Summary

NASA calculated Tropical Storm Darby's rainfall rates over Hawaii

Tropical Storm Darby brought rainfall, gusty winds and rough surf to the Hawaiian Islands over the weekend of July 23 and 24, and was still raining over them on Monday, July 25, 2016. The Global Precipitation Measurement mission or GPM core satellite passed over the islands and calculated rainfall rates from Darby. read more

Process could make key biodegradable polymer stronger and longer-lasting

PROVIDENCE, R.I. [Brown University] -- Polylactic acid, or PLA, is a biodegradable polymer commonly used to make a variety of products from disposable cups to medical implants to drug delivery systems. A team of Brown University researchers...Show More Summary

NASA sees formation of Tropical Depression 05W in infrared

Tropical Depression 05W developed on July 25, 2016 as NASA's Aqua satellite passed overhead and captured temperature data on the storm as it came together. read more

NASA scans Tropical Storm Frank's winds

RapidScat is an instrument that flies aboard the International Space Station and measures winds over an ocean surface. RapidScat provided a look at the winds around Tropical Storm Frank in the Eastern Pacific and saw strongest windsShow More Summary
