How will people interact with technology in the future?

New research that discusses how people will interact with technology in the future will be presented this week at one of the world's most important conferences on human-computer interfaces, ACM CHI 2016, in San Jose, USA [7-12 May].

Study finds declining sulfur levels

With the move from burning coal to natural gas and low-sulfur coal and an increase in the use of scrubbers, only about 25 percent as much atmospheric sulfur is available today, compared to 40 years ago.

Sulfur balances in agricultural fields are now negative, with more removed each year in crop harvests and leaching than is added from fertilizers and deposition.

Fields with tile drainage move sulfate quickly to surface waters, contributing to the low levels in the soil.

Effects of spectral quality, intensity of LEDs

ALMERIA, SPAIN - In horticultural operations, light-emitting diode (LED) lamps are becoming recognized as an important advance in artificial lighting. Among other benefits, LED lighting systems can offer durability, long operating lifetimes, and high energy efficiency. Researchers published a study in the March 2016 issue of HortScience that shows that continuous spectrum LEDs made specifically for horticultural can be superior to conventional white LEDs in terms of plant response and energy efficiency.

Salmon smolts find safety in numbers

Using tags surgically implanted into thousands of juvenile salmon, UBC researchers have discovered that many fish die within the first few days of migration from their birthplace to the ocean.

"We knew that on average 10 to 40 million smolts leave Chilko Lake every year and only about 1.5 million return as adults two years later," said Nathan Furey, researcher and a PhD candidate in the faculty of forestry. "It's always been a mystery about what happens in between."

Rapid, low-cost, and portable test for Zika effectively detects virus in monkeys

Doctors working hundreds of miles away from the nearest hospital could soon have a way to quickly detect Zika virus in blood or saliva samples for less than a dollar per patient. In a proof-of-concept demonstration published May 6 in Cell, Wyss Institute for Biologically Inspired Engineering researchers at Harvard University show how a new Zika diagnostic, which can be freeze-dried and stored for up to a year, successfully detects the virus in the serum of infected macaques.

'Hammerhead' creature was world's first plant-eating marine reptile

In 2014, scientists discovered a bizarre fossil--a crocodile-sized sea-dwelling reptile that lived 242 million years ago in what today is southern China. Its head was poorly preserved, but it seemed to have a flamingo-like beak. But in a paper published today in Science Advances, paleontologists reveal what was really going on--that "beak" is actually part of a hammerhead-shaped jaw apparatus, which it used to feed on plants on the ocean floor. It's the earliest known example of an herbivorous marine reptile.

Scientists track Greenland's ice melt with seismic waves

Researchers from MIT, Princeton University, and elsewhere have developed a new technique to monitor the seasonal changes in Greenland's ice sheet, using seismic vibrations generated by crashing ocean waves. The results, which will be published in the journal Science Advances, may help scientists pinpoint regions of the ice sheet that are most vulnerable to melting. The technique may also set better constraints on how the world's ice sheets contribute to global sea-level changes.

Teaching computers to understand human languages

Researchers at the University of Liverpool have developed a set of algorithms that will help teach computers to process and understand human languages.

Whilst mastering natural language is easy for humans, it is something that computers have not yet been able to achieve. Humans understand language through a variety of ways for example this might be through looking up it in a dictionary, or by associating it with words in the same sentence in a meaningful way.

Understanding tiny droplets can make for better weather forecasts

When you see how difficult it is to get even next week's weather forecast right, you can imagine the challenges researchers are faced with when it comes to predicting the weather decades from now.

Climatologists need good models to predict climate change over time, but to predict how the Earth's climate is changing, they also need to understand how water droplets behave.

Rapid, low-cost detection of Zika virus using paper-based synthetic gene networks

Toronto, ON - University of Toronto Assistant Professor of Pharmacy Keith Pardee and an international team of collaborators, including scientists from the Wyss Institute at Harvard University, have developed a low-cost, easy-to-use diagnostic platform for detecting the Zika virus.

Clinicians need to screen 'nicotine naive' teenagers for vaping, says UB addictions expert

BUFFALO, N.Y. - During a checkup, physicians and nurses often ask about drinking habits, safe sex practice or cigarette use. Vaping is rarely mentioned.

This discussion is urgently needed with teen patients, who are either uninformed or misinformed about the dangers and risks associated with electronic cigarettes, says Nancy Campbell-Heider, PhD, a University at Buffalo addictions and high-risk adolescent behavior expert.

Molybdenum disulfide holds promise for light absorption

Mechanics know molybdenum disulfide (MoS2) as a useful lubricant in aircraft and motorcycle engines and in the CV and universal joints of trucks and automobiles. Rice University engineering researcher Isabell Thomann knows it as a remarkably light-absorbent substance that holds promise for the development of energy-efficient optoelectronic and photocatalytic devices.

EARTH: Growth rings in rocks reveal past climate

Alexandria, VA - For years, scientists have used mineral, sediment and ice layers, deposited intermittently throughout geologic time, to track the global climate record. These can come from caves, lakes, the oceans and ice sheets. But over the course of the last decade a new method has been developed that presents an opportunity for geoscientists to assess global climate history in almost any arid landscape.

Speedy ion conduction in solid electrolytes clears road for advanced energy devices

In a rechargeable battery, the electrolyte transports lithium ions from the negative to the positive electrode during discharging. The path of ionic flow reverses during recharging. The organic liquid electrolytes in commercial lithium-ion batteries are flammable and subject to leakage, making their large-scale application potentially problematic. Solid electrolytes, in contrast, overcome these challenges, but their ionic conductivity is typically low.

13 days: Scientists develop human embryos through early post-implantation stages for first time

A new technique that allows embryos to develop in vitro beyond the implantation stage (when the embryo would normally implant into the womb) has been developed by scientists at the University of Cambridge allowing them to analyse for the first time key stages of human embryo development up to 13 days after fertilisation. The technique could open up new avenues of research aimed at helping improve the chances of success of IVF.
