Researchers discover that privacy-preserving tools leave private data anything but Posted: 03 Mar 2021 01:16 PM PST Researchers explored whether private data could still be recovered from images that had been 'sanitized'' by such deep-learning discriminators as privacy protecting GANs (PP-GANs).

Nature: New compound for male contraceptive pill Posted: 03 Mar 2021 01:16 PM PST In a new article spells out an innovative strategy that has led to the discovery of a natural compound as a safe, effective and reversible male contraceptive agent in pre-clinical animal models. Despite tremendous efforts over the past decades, the progress in developing non-hormonal male contraceptives has been very limited.

High end of climate sensitivity in new climate models seen as less plausible Posted: 03 Mar 2021 01:16 PM PST Researchers found that the latest generation of high-sensitivity climate models do not provide a plausible scenario of Earth's future climate. These models project that clouds moderate greenhouse gas-induced warming -- particularly in the northern hemisphere -- much more than climate records show actually happens. The results provide a cautionary tale on interpreting climate simulations, which can determine the aggressiveness of carbon-mitigation policies.

Climate change 'winners' may owe financial compensation to polluters Posted: 03 Mar 2021 01:16 PM PST New economic and philosophical research argues that policymakers must consider both the beneficial effects of climate change to 'climate winners' as well as its costs in order to appropriately incentivize actions that are best for society and for the environment.

Small-scale fisheries offer strategies for resilience in the face of climate change Posted: 03 Mar 2021 11:48 AM PST Small-scale fisheries, which employ about 90 percent of the world's fishers and supply half the fish for human consumption, are on the frontlines of climate change. They may offer insights into resilience.

Ghosts of past pesticide use can haunt organic farms for decades Posted: 03 Mar 2021 11:26 AM PST Although the use of pesticides in agriculture is increasing, some farms have transitioned to organic practices and avoid applying them. But it's uncertain whether chemicals applied to land decades ago can continue to influence the soil's health after switching to organic management. Now, researchers have identified pesticide residues at 100 Swiss farms, including all the organic fields studied, with beneficial soil microbes' abundance negatively impacted by their occurrence.

New, highly precise 'clock' can measure biological age Posted: 03 Mar 2021 11:26 AM PST Scientists have developed a method that can determine an organism's biological age with unprecedented precision. Researchers expect new insights into how the environment, nutrition, and therapies influence the aging process.

Color blindness-correcting contact lenses Posted: 03 Mar 2021 11:26 AM PST Imagine seeing the world in muted shades -- gray sky, gray grass. Some people with color blindness see everything this way, though most can't see specific colors. Tinted glasses can help, but they can't be used to correct blurry vision. And dyed contact lenses currently in development for the condition are potentially harmful and unstable. Now researchers report infusing contact lenses with gold nanoparticles to create a safer way to see colors.

Study reveals details of immune defense guidance system Posted: 03 Mar 2021 11:25 AM PST At the beginning of an immune response, a molecule known to mobilize immune cells into the bloodstream, where they home in on infection sites, rapidly shifts position, a new study shows. Researchers say this indirectly amplifies the attack on foreign microbes or the body's own tissues.

Mantis shrimp inspires new breed of light sensors Posted: 03 Mar 2021 11:25 AM PST Inspired by the eyes of mantis shrimp, researchers have developed a new kind of optical sensor that is small enough to fit on a smartphone but is capable of hyperspectral and polarimetric imaging.

Genomics study identifies routes of transmission of coronavirus in care homes Posted: 03 Mar 2021 11:24 AM PST Genomic surveillance -- using information about genetic differences between virus samples -- can help identify how SARS-CoV-2 spreads in care home settings, whose residents are at particular risk, according to new research.

Fluorescent nanodiamonds successfully injected into living cells Posted: 03 Mar 2021 11:24 AM PST As odd as it sounds, many scientists have attempted to place extremely small diamonds inside living cells. Why? Because nanodiamonds are consistently bright and can give us unique knowledge about the inner life of cells over a long time. Now physics researchers have succeeded in injecting a large number of nanodiamonds directly to the cell interior.

Prehistoric killing machine exposed Posted: 03 Mar 2021 11:24 AM PST 3D imaging of the dinocephalian, Anteosaurus, shows that this massive premammalian reptile that grew to the size of a full-grown hippopotamus, was a highly agile killing machine, and not a slow stodgy scavenger as previously believed.

Accelerating gains in abdominal fat during menopause tied to heart disease risk Posted: 03 Mar 2021 11:24 AM PST Women who experience an accelerated accumulation of abdominal fat during menopause are at greater risk of heart disease, even if their weight stays steady, according to a new analysis. The study -- based on a quarter century of data collected on hundreds of women -- indicates that measuring waist circumference during preventive health care appointments for midlife women could be a better early indicator of heart disease risk than weight or BMI.

No second chance to make trusting first impression, or is there? Posted: 03 Mar 2021 11:24 AM PST It is important to make a good first impression and according to new research trusting a person early on can have benefits over the life of the relationship, even after a violation of that trust.

Researchers observed that the intake of those extracts can reduce facial dysmorphology in children with Down syndrome when taken during the first three years of life. Additional experimental research in mice confirmed the positive effects at low doses. However, the researchers also found that high doses can disrupt facial and bone development.

New generation of tiny, agile drones introduced Posted: 03 Mar 2021 06:35 AM PST Researchers developed an insect-size drone with soft actuators -- akin to muscles -- that are agile and resilient to collisions. The advance could boost aerial robots' repertoire, allowing them to operate in cramped spaces and withstand collisions.

Key steps discovered in production of critical immune cell Posted: 03 Mar 2021 06:34 AM PST Researchers have uncovered a process cells use to fight off infection and cancer that could pave the way for precision cancer immunotherapy treatment. Through gaining a better understanding of how this process works, researchers hope to be able to determine a way of tailoring immunotherapy to better fight cancer.

How 'green' are environmentally friendly fireworks? Posted: 03 Mar 2021 05:14 AM PST Fireworks are used in celebrations around the world, including Independence Day in the U.S., the Lantern Festival in China and the Diwali Festival in India. However, the popular pyrotechnic displays emit large amounts of pollutants into the atmosphere, sometimes causing severe air pollution. Now, researchers have estimated that, although so-called environmentally friendly fireworks emit 15-65% less particulate matter than traditional fireworks, they still significantly deteriorate air quality.

Dietary fats interact with grape tannins to influence wine taste Posted: 03 Mar 2021 05:13 AM PST Wine lovers recognize that a perfectly paired wine can make a delicious meal taste even better, but the reverse is also true: Certain foods can influence the flavors of wines. Now, researchers have explored how lipids -- fatty molecules abundant in cheese, meats, vegetable oils and other foods -- interact with grape tannins, masking the undesirable flavors of the wine compounds.

Mysteries of soupfin shark migration and reproduction Posted: 03 Mar 2021 05:13 AM PST First conclusive evidence in any animal of triennial philopatry, referring to the periodic return of an animal to the same location. Study has implications for conservation of this critically endangered species.

Quick-learning cuttlefish pass 'the marshmallow test' Posted: 02 Mar 2021 06:20 PM PST Cuttlefish can delay gratification - wait for a better meal rather than be tempted by the one at hand - and those that can wait longest also do better in a learning test, scientists have discovered. This intriguing report marks the first time a link between self-control and intelligence has been found in an animal other than humans and chimpanzees.
