Artificially sweetened drinks may not be heart healthier than sugary drinks

Science Daily - 19 hours 36 min ago
Sugary drinks and artificially sweetened beverages are associated with a higher risk of cardiovascular disease, which suggests artificially sweetened beverages may not be the healthy alternative they are often claimed to be, according to a research letter.

Dog training methods help researchers teach robots to learn new tricks

Science Daily - 26/10/2020
With a training technique commonly used to teach dogs to sit and stay, computer scientists showed a robot how to teach itself several new tricks, including stacking blocks. With the method, the robot, named Spot, was able to learn in days what typically takes a month.

Bridges with limb-inspired architecture can withstand earthquakes, cut repair costs

Science Daily - 26/10/2020
Structural damage to any of the nation's ailing bridges can come with a hefty price of billions of dollars in repairs. New bridge designs promise more damage-resistant structures and, consequently, lower restoration costs. But if these designs haven't been implemented in the real world, predicting how they can be damaged and what repair strategies should be implemented remain unresolved.

How cells use mechanical tension sensors to interact with their environment

Science Daily - 26/10/2020
In a painstaking experiment, scientists suspended a single protein filament between two microscopic beads. Their results have shed light on an elusive process in which cells receive and respond to mechanical cues.

Neuron-based gene expression study reveals insights on fear and its regulation

Science Daily - 26/10/2020
The expression of a gene called CREB in certain neurons may function as a switch to regulate feelings of fear and its extinction.

Odds are good for unique 2D compound

Science Daily - 26/10/2020
Engineers make 2D materials for valleytronics, a platform for information processing and storage that relies on the manipulation of electrons' positions in energetic 'valleys.'

Rolling out next-gen nanocars

Science Daily - 26/10/2020
Researchers continue to advance the science of single-molecule machines with a new lineup of nanocars, in anticipation of the next international Nanocar Race in 2022.

Can scientists take the STING out of common respiratory viruses?

Science Daily - 26/10/2020
Scientists have made a curious discovery about a well-known human protein that helps the immune system fight viral infections. Researchers found that one class of viruses actually requires this protein to infect cells and replicate.

Mmore complete view of massive asteroid Psyche

Science Daily - 26/10/2020
A new study discusses several new views of the asteroid 16 Psyche, including the first ultra-violet observations. The study paints a clearer view of the asteroid than was previously available.

Tiny moon shadows may harbor hidden stores of ice

Science Daily - 26/10/2020
Hidden pockets of water could be much more common on the surface of the moon than scientists once suspected, according to new research.

US corn crop's growing sensitivity to drought revealed

Science Daily - 26/10/2020
New management approaches and technology have allowed the US. Corn Belt to increase yields despite some changes in climate. However, soil sensitivity to drought has increased significantly, according to a new study that could help identify ways to reverse the trend.

Time-keeping brain protein influences memory

Science Daily - 26/10/2020
Upsetting the brain's timekeeping can cause cognitive impairments, like when jetlag makes you feel foggy and forgetful. These impairments may stem from disrupting a protein that aligns the brain's time-keeping mechanism to the correct time of day, according to new research in fruit flies.

On the moon, water everywhere but not a drop to drink yet

The Hindu:Science - 26/10/2020
Earth is a wet world, with vast salty oceans, large freshwater lakes and ice caps that serve as water reservoirs.

NASA's SOFIA discovers water on sunlit surface of Moon

Science Daily - 26/10/2020
NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.

Data reveals evidence of molecular absorption in the atmosphere of a hot Neptune

Science Daily - 26/10/2020
An international team of scientists recently measured the spectrum of the atmosphere of a rare hot Neptune exoplanet, whose discovery by NASA's Transiting Exoplanet Survey Satellite (TESS) was announced just last month.

State gun laws may help curb violence across state lines: study

Science Daily - 26/10/2020
Researchers find that strong state firearm laws are associated with fewer firearm homicides -- both within the state where the laws are enacted and across state lines. Conversely, weak firearm laws in one state are linked to higher rates of homicides in neighboring states.

Hard physical work may significantly increase the risk of dementia

Science Daily - 26/10/2020
Men in jobs with hard physical work have a higher risk of developing dementia compared to men doing sedentary work, new research reveals. The researchers therefore urge the health authorities to make their recommendations concerning physical activity more specific.

Land management in forest and grasslands: How much can we intensify?

Science Daily - 26/10/2020
Intensive land-use reduces beneficial effects of biodiversity on ecosystem services. It assessed the effects of land management on the links between biodiversity, ecosystem functions and ecosystem services, identified thresholds of management intensity, most important species groups for driving services, and the ecosystem services at risk.

How exercise stalls cancer growth through the immune system

Science Daily - 26/10/2020
People with cancer who exercise generally have a better prognosis than inactive patients. Now, researchers have found a likely explanation of why exercise helps slow down cancer growth in mice: Physical activity changes the metabolism of the immune system's cytotoxic T cells and thereby improves their ability to attack cancer cells.

Powering the future: New insights into how alkali-metal doped flexible solar cells work

Science Daily - 26/10/2020
A group of scientists has discovered that the amount of alkali metal introduced into crystals of flexible thin-film solar cells influences the path that charge carriers take to traverse between electrodes, thereby affecting the light-to-electricity conversion efficiency of the solar cell. Given the immense application potential that such solar cells have today, this finding could be key to ushering in a green future.
