Researchers 'reprogram' network of brain cells in mice with thin beam of light
Posted: 11 Aug 2016 11:35 AM PDT
Neurons that fire together really do wire together, says a new study, 
suggesting that the three-pound computer in our heads may be more malleable 
than we think.




Global warming's next surprise: Saltier beaches
Posted: 11 Aug 2016 11:26 AM PDT
Batches of sand from a beach on the Delaware Bay are yielding insights into the 
powerful impact of temperature rise and evaporation along the shore that are in 
turn challenging long-held assumptions about what causes beach salinity to 
fluctuate in coastal zones that support a rich network of sea creatures and 
plants.




Hubble uncovers a galaxy pair coming in from the wilderness
Posted: 11 Aug 2016 11:26 AM PDT
Two tiny dwarf galaxies have been observed that have wandered from a vast 
cosmic wilderness into a nearby 'big city' packed with galaxies. After being 
quiescent for billions of years, they are ready to party by starting a 
firestorm of star birth.




Much ado about nothing: Astronomers use empty space to study the universe
Posted: 11 Aug 2016 11:26 AM PDT
An international team of astronomers reports that they were able to achieve 
four times better precision in measurements of how the universe's visible 
matter is clustered together by studying the empty spaces in between.




Lions in West and Central Africa apparently unique
Posted: 11 Aug 2016 09:05 AM PDT
Lions in West and Central Africa form a unique group, only distantly related to 
lions in East and Southern Africa, biologists have discovered.




Venus may have been habitable, NASA climate modeling suggests
Posted: 11 Aug 2016 09:04 AM PDT
Venus may have had a shallow liquid-water ocean and habitable surface 
temperatures for up to two billion years of its early history, according to 
NASA computer modeling of the planet's ancient climate.




In a race for Cheetos, magpies win, but crows steal
Posted: 11 Aug 2016 07:11 AM PDT
In urban neighborhoods, magpies often nest near their cousin corvid species, 
crows. Nesting near a bigger bird affords them some extra defense against 
predators. But do they pay a food penalty? To find out, ecologists presented 
the birds with a set of Cheetos challenges.




Orangutan able to guess a taste without sampling it, just like us
Posted: 11 Aug 2016 07:10 AM PDT
Without having tasted a new juice mix before, an orangutan in a Swedish zoo has 
enough sense to know whether it will taste nice or not based on how he 
recombined relevant memories from the past. Only humans were thought to have 
this ability of affective forecasting, in which prior experiences are used to 
conjure up mental pictures about totally new situations.




Our ancestors: More gorilla than chimp
Posted: 11 Aug 2016 07:10 AM PDT
A new study that for the first time examined the internal anatomy of a fossil 
human relative's heel bone, or calcaneus, shows greater similarities with 
gorillas than chimpanzees.




Paraplegics regain some feeling, movement after using brain-machine interfaces
Posted: 11 Aug 2016 07:10 AM PDT
Eight people who have spent years paralyzed from spinal cord injuries have 
regained partial sensation and muscle control in their lower limbs after 
training with brain-controlled robotics, according to a new study.




Britain's last hunter-gatherers discovered using breakthrough analysis of bone 
fragments
Posted: 11 Aug 2016 05:59 AM PDT
Archaeologists have identified rare human bones from the UK dating to the Late 
Mesolithic era (around 4000 BC, just prior to the arrival of farming in 
Britain) using an innovative new bone collagen analysis technique.

 Could we one day control the path of lightning? 
 
 Posted: 19 Jun 2015 12:21 PM PDT
   
Lightning path remains unpredictable, but at a smaller scale, discharges 
between two electrodes can be guided by laser beams. Scientists have discovered 
a way to guide electric discharges -- and even steer them around obstacles -- 
through the clever use of lasers.   
 
 
 
 
 
  
 
 Sixth mass extinction is here: Humanity's existence threatened 
 
 Posted: 19 Jun 2015 12:21 PM PDT
   
Biologists have use highly conservative estimates to prove that species are 
disappearing faster than at any time since the dinosaurs' demise.   
 
 
 
 
 
  
 
 Chemists devise technology that could transform solar energy storage 
 
 Posted: 19 Jun 2015 07:36 AM PDT
   
Chemists have developed a major improvement to capture and retain energy from 
sunlight, where the stored energy can last dramatically longer than current 
solar technology allows -- up to several weeks, instead of the microseconds 
found in today's rooftop solar panels.   
 
 
 
 
 
  
 
 How bats actually fly to find their prey 
 
 Posted: 19 Jun 2015 05:46 AM PDT
   
New research helps elucidate how bats actually fly to find their prey. Every 
night a bat puts in 600-700 kilometres of airtime. Flying low, the animals 
catch insects at speeds of around 40 metres per second. At night the bat uses 
its hearing to navigate its way to prey. Bats catch insects continuously using 
echolocation, an advanced navigation system.   
 
 
 
 
 
  
 
 First solar cell made of highly ordered molecular frameworks 
 
 Posted: 19 Jun 2015 05:44 AM PDT
   
Researchers have developed a material suited for photovoltaics. For the first 
time, a functioning organic solar cell consisting of a single component has 
been produced on the basis of metal-organic framework compounds (MOFs). The 
material is highly elastic and might also be used for the flexible coating of 
clothes and deformable components.   
 
 
 
 
 
  
 
 Lefties are all right with kangaroos 
 
 Posted: 18 Jun 2015 10:42 AM PDT
   
Kangaroos prefer to use one of their hands over the other for everyday tasks in 
much the same way that humans do, with one notable difference: generally 
speaking, kangaroos are lefties. The finding is the first to consider 
handedness in wild kangaroos, and challenges the notion that 'true' handedness 
among mammals is a feature unique to primates.   
 
 
 
 
 
  
 
 Evidence of key ingredient during dawn of life 
 
 Posted: 18 Jun 2015 09:20 AM PDT
   
Scientists have provided the first direct experimental evidence for how 
primordial proteins developed the ability to accelerate the central chemical 
reaction necessary to synthesize proteins and thus allow life to arise not long 
after Earth was created.   
 
 
 
 
 
  
 
 Cellulose from wood can be printed in 3-D 
 
 Posted: 17 Jun 2015 06:17 AM PDT
   
A group of researchers have managed to print and dry three-dimensional objects 
made entirely by cellulose for the first time with the help of a 3D-bioprinter. 
They also added carbon nanotubes to create electrically conductive material. 
The effect is that cellulose and other raw material based on wood will be able 
to compete with fossil-based plastics and metals in the on-going additive 
manufacturing revolution, which started with the introduction of the 
3D-printer.
