Air quality in 'green' housing affected by toxic chemicals in building materials

Tue, 12 Sep 17 00:10:50 -0700

Indoor air pollution can be a problem in many homes, even in eco-friendly buildings. Thanks to a new innovative study led by Silent Spring Institute, researchers have a better idea of where these pollutants come from -- which ones come from chemicals leaching out of building materials and which ones from the personal items people bring into their homes. The findings could inform the development of new green building standards and lead to healthier housing, especially for low-income communities.

Doctors can now predict the severity of your disease by measuring molecules

Tue, 12 Sep 17 00:02:40 -0700

Payments to rural communities offer a new opportunity to restore China's native forests

Thu, 03 Aug 17 00:01:10 -0700

Despite massive efforts at reforestation, China's native forests continue to be displaced by plantations. A new study argues that rural communities could help reverse this trend if they were given incentives to protect and restore native forests on their own land. A proposed new umbrella policy for environmental protection in China currently falls short of the measures needed, but if amended, could provide a unique opportunity to benefit rural communities and the environment.

Targeting 'Achilles' heel' could supercharge breast cancer treatment

Wed, 02 Aug 17 00:14:20 -0700

A new class of anti-cancer agents targeting cancer cells' 'Achilles' heel' could help to supercharge breast cancer treatment, improving outcomes for the most aggressive types of breast cancer. Combining anti-cancer compound S63845 with currently used cancer drugs was more effective in killing triple negative breast cancers and HER2-positive breast cancers. This is the first time the S63845 compound has been shown to be effective in breast cancer, suggesting it should be investigated in clinical trials.

New algorithm finds the optimal bond breaking point for single molecules

Tue, 01 Aug 17 00:10:50 -0700

Recent developments in atomic-force microscopy have enabled researchers to apply mechanical forces to individual molecules to induce chemical reactions. A research team from Spain and Germany has now developed a first-of-its-kind algorithm that determines the minimal force it takes to reach the optimal bond breaking point (BBP) at the molecular level to mechanically induce a chemical reaction. They report their findings this week in The Journal of Chemical Physics.

Size matters, and so do temperature and habitat, to scavengers and the carcasses they eat

Tue, 01 Aug 17 00:13:00 -0700

Size matters in the carrion world, and so do habitat and temperature. New research has shed fresh light on the largely understudied area of vertebrate scavenging ecology.

Why Tyrannosaurus was a slow runner

Mon, 17 Jul 17 00:13:20 -0700

A beetle is slower than a mouse, which is slower than a rabbit, which is slower than a cheetah... which is slower than an elephant? No! For small to medium-sized animals, larger also means faster, but for really large animals, when it comes to speed, everything goes downhill again. For the first time, researchers have described in the journal Nature Ecology and Evolution how this parabola-like relationship between body size and speed comes about.

Patients whose emergency surgery is delayed are at higher risk of death

Mon, 10 Jul 17 00:05:20 -0700

Delays for emergency surgery were associated with a higher risk of death for patients in hospital -- and higher costs -- yet these delays were largely due to lack of operating rooms and staff, and other system issues, found a new study published in CMAJ.

Saving the paintbrush lily from extinction

Wed, 05 Jul 17 00:13:10 -0700

The optical force of the photon sets the medium atoms in motion and makes them carry 92 percent of the total momentum of light, in the case of silicon.

Hubble eyes a powerful galaxy with a password name

Fri, 30 Jun 17 00:14:20 -0700

Not all galaxies have the luxury of possessing a simple moniker or quirky nickname. This impressive galaxy imaged by the NASA/ESA Hubble Space Telescope is one of the unlucky ones, and goes by a name that looks more like a password for a computer: 2XMM J143450.5+033843.

As climate stirs Arctic sea ice faster, pollution tags along

Tue, 27 Jun 17 00:07:10 -0700

A warming climate is not just melting the Arctic's sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country's waters, says a new study.

Septic systems are a major source of emerging contaminants in drinking water

Mon, 26 Jun 17 00:02:00 -0700

A new analysis shows that septic systems in the United States routinely discharge pharmaceuticals, consumer product chemicals, and other potentially hazardous chemicals into the environment. The study is the most comprehensive assessment to date of septic systems as important sources of emerging contaminants, raising health concerns since many of these chemicals, once discharged, end up in groundwater and drinking water supplies.

Outside auditors should be wary of information provided by management, MU study shows

Mon, 20 Mar 17 00:02:30 -0700

Nate Newton, assistant professor of accountancy in the Trulaske College of Business at the University of Missouri, and his co-authors asked practicing auditors to estimate expenses relating to a year-end fire at a fictional company. Newton and his co-authors found that a group given estimates supporting the company's preferred expenses were more than twice as likely to approve of management's preference compared to auditors who received a set of estimates more representative of the full range of potential expenses.

From the butterfly's wing to the tornado: Predicting turbulence

Wed, 15 Mar 17 00:13:40 -0700

Remember the butterfly-triggers-tornado adage? Chaos theory says calculating turbulence to find out if that's true must be impossible. Now, physicists are latching onto turbulent patterns with digital optics and math. Their resulting forecasts jibe with actual turbulent flows. Embeddable video:

Robber fly's aerial hunting skill relies on extreme visual acuity

Thu, 09 Mar 17 00:11:40 -0800

You might expect that the miniature brains and eyes of tiny robber flies would limit their ability to launch sophisticated in-flight predatory attacks on their prey. But, according to researchers reporting in Current Biology on March 9 who've captured the rice-sized predators' tactics on film, that's not so.

Rapid changes point to origin of ultra-fast black hole 'burps'

Wed, 01 Mar 17 00:03:20 -0800

Scientists have made the most detailed observation yet of a black hole outflow, from the active galaxy IRAS 13224-3809. The outflow's temperature changed on time scales of less than an hour -- hundreds of times faster than ever seen before. The rapid fluctuations in the outflow's temperature also indicated that the outflow was responding to X-ray emissions from the accretion disk, a dense zone of gas and other materials that surrounds the black hole.
