Working lands play a key role in protecting biodiversity

Thursday October 18th, 2018 07:11:03 PM
Diversifying working lands -- including farmland, rangeland and forests -- may be key to preserving biodiversity in the face of climate change, says a new review article. These changes could extend the habitat of critters like bats, but also much larger creatures like bears, elk and other wildlife, outside the boundaries of protected areas, while creating more sustainable, and potentially more productive, working lands.

Genetic breakthrough will aid whitebark pine conservation efforts

Thursday October 18th, 2018 07:10:53 PM
A research team for the first time developed reliable genetic markers known as nuclear microsatellites for the whitebark pine, a discovery that could improve the tree's prospects for survival. Whitebark pine, which is declining rapidly nearly range-wide, is currently being considered for listing under the Endangered Species Act.

Superflares from young red dwarf stars imperil planets

Thursday October 18th, 2018 06:12:04 PM
Flares from the youngest red dwarfs surveyed are 100 to 1,000 times more energetic than when the stars are older. This younger age is when terrestrial planets are forming around their stars.

150-million-year old, piranha-like specimen is earliest known flesh-eating fish

Thursday October 18th, 2018 06:11:29 PM
Researchers have described a remarkable new species of fish that lived in the sea about 150 million years ago in the time of the dinosaurs. The new species of bony fish had teeth like a piranha, which the researchers suggest they used as piranhas do: to bite off chunks of flesh from other fish.

Not all prion strains interfere with each other

Thursday October 18th, 2018 06:11:18 PM
The first example of prion strains that replicate independently in vitro and in vivo suggests that strain diversity may be greater than previously thought, according to a new study.

Asthma's effects on airways at the single cell level

Thursday October 18th, 2018 06:11:13 PM
By sequencing genetic material at a cell-by-cell level, researchers have described how type 2-high asthma affects the airways and results in mucus production with more detail than ever before. These findings, which help move forward scientific understanding of the biology behind asthma and could inform the development of targeted treatments for asthma and other airway diseases.

New tool helps align investment with objectives in biodiversity conservation

Thursday October 18th, 2018 06:11:10 PM
Researchers developed a tool, called the Recovery Explorer, that can be used to help guide conservation scientists in making decisions on how to best use limited funds to conserve the greatest number of species. The tool was developed in collaboration with US Fish & Wildlife Services scientists in a two-year project supported by the National Socio-Environmental Synthesis Center.

First proof of quantum computer advantage

Thursday October 18th, 2018 06:11:07 PM
Quantum computers promise to revolutionize the future of computing. Scientists have now demonstrated for the first time that quantum computers do indeed offer advantages over conventional computers. They developed a quantum circuit that can solve a problem that is unsolvable using any equivalent classical circuit.

New insight into the evolution of the nervous system

Thursday October 18th, 2018 06:11:05 PM
Pioneering research has given a fascinating fresh insight into how animal nervous systems evolved from simple structures to become the complex network transmitting signals between different parts of the body.

3D-printed supercapacitor electrode breaks records in lab tests

Thursday October 18th, 2018 06:11:02 PM
Scientists have reported unprecedented performance results for a supercapacitor electrode. The researchers fabricated electrodes using a printable graphene aerogel to build a porous three-dimensional scaffold loaded with pseudocapacitive material. In laboratory tests, the novel electrodes achieved the highest areal capacitance (electric charge stored per unit of electrode surface area) ever reported for a supercapacitor.

Electrical properties of dendrites help explain our brain's unique computing power

Thursday October 18th, 2018 06:10:57 PM
Neuroscientists have discovered that human dendrites have very different electrical properties from those of other species. These differences may contribute to the enhanced computing power of the human brain.

Nanodiamonds as photocatalysts

Thursday October 18th, 2018 04:52:10 PM
Diamond nanomaterials are considered hot candidates for low-cost photocatalysts. They can be activated by light and can then accelerate certain reactions between water and CO2 and produce carbon-neutral 'solar fuels'. The EU project DIACAT has now doped such diamond materials with boron and shown at BESSY II how this could significantly improve the photocatalytic properties.

Aerobic exercise has antidepressant treatment effects

Thursday October 18th, 2018 04:52:07 PM
An analysis of randomized controlled clinical trials indicates that supervised aerobic exercise has large antidepressant treatment effects for patients with major depression.

Neo-colonial attitudes to security in war-torn nations out-of-date and unhelpful

Thursday October 18th, 2018 04:51:54 PM
Developed countries imposing their own Security Sector Reform (SSR) processes onto nations recovering from war often rely on entrenched colonial attitudes with no guarantee of success. Researchers looked at the Democratic Republic Congo and Nepal contrasting their outcomes and examining the reasons for success or failure of SSR policies based on Europe. They question whether the systems work in their countries of origin where statistics show ongoing institutional racism.

Unfolding secret stability of bendy straws

Thursday October 18th, 2018 04:51:49 PM
Collapsible dog bowls and bendable straws seem to work on a common principle, snapping into stable and useful states, but mechanisms have remained elusive. Now a team led by polymer scientists discuss how 'pre-stress' built into the structure helps them function.

Colored filter improves dyslexic children's reading speed

Thursday October 18th, 2018 04:51:48 PM
Volunteers aged 9-10 with dyslexia took less time to read passages from children's books, possibly thanks to attenuated excitability of the cerebral cortex.

'Geek Girl' gamers are more likely to study science and technology degrees

Thursday October 18th, 2018 04:51:44 PM
Girls who play video games are three times more likely to choose physical science, technology, engineering or maths (PSTEM) degrees compared to their non-gaming counterparts, according to new research.

New tool uses your smartphone camera to track your alertness at work

Thursday October 18th, 2018 04:51:41 PM
Our level of alertness rises and falls over the course of a workday, sometimes causing our energy to drop and our minds to wander just as we need to perform important tasks. To help understand these patterns and improve productivity, researchers have developed a tool that tracks alertness by measuring pupil size, captured through a burst of photographs taken every time users unlock their smartphones.

New material, manufacturing process use sun's heat for cheaper renewable electricity

Thursday October 18th, 2018 04:51:38 PM
Scientists have developed a new material and manufacturing process that would make one way to use solar power -- as heat energy -- more efficient in generating electricity.

Kids health outcomes have more to do with parents level of education than income

Thursday October 18th, 2018 04:51:36 PM
A recent study finds that parents educated beyond high school have healthier families, as they invest more in family health care which reduces the likelihood of adverse medical conditions.
