A new group of archaea are the closest relatives to complex cellular life ever found and suggest our microbial ancestors were more complex than we thought
When I started Fish 2.0, many investors, foundations, and even seafood experts said it would be difficult to get more than 50 entries in a competition for sustainable seafood businesses. They were not seeing many innovative seafood businesses, and they believed most of those they did see were not looking for investment. The inaugural competition in 2013 showed that assessment was off the mark: it drew 83 entries. This year’s application period, which closed April 27, shows that innovation in the seafood sector is positively surging: we received 170 entries, more than double the number in the previous field.
That is fantastic news for our oceans and the people who depend on them. About 70 percent of the world’s fisheries are fully exploited, overexploited or have already suffered a collapse under the pressure of a $390 billion global seafood market. Yet analysts expect seafood demand to double by 2050, and island and coastal communities around the world depend on seafood for both sustenance and economic health. The situation demands sustainably managed fisheries and environmentally responsible aquaculture.
This year’s Fish 2.0 applications—from about 100 start-ups and 70 ventures that are already successfully selling and scaling—illustrate the diversity of innovation happening in the sector. Some of these businesses are shortening supply chains for value-added sustainable seafood products in the Pacific Islands, Alaska, Japan and Thailand. Some are using advanced aquaculture techniques to reduce energy costs, wastes and loss from disease, or are developing new fish feeds. Others are improving seafood storage systems to reduce logistics costs, improve quality and open new markets; bringing convenient sustainable seafood products to consumers; developing software to make fishing and fish farming businesses more efficient and systems that make supply chains traceable; or providing healthy foods and income to communities that have few —> Read More
Scientists have discovered a new type of stem cell that could potentially generate mature, functional tissues. They report using these new stem cells to develop the first reliable method for integrating human stem cells into nonviable mouse embryos in a laboratory dish in such a way that the human cells began to differentiate into early-stage tissues. —> Read More
In our fast-paced, competitive culture, we tend to notice and worry about what’s lacking in our lives. Because of our drive to succeed, we focus on what stands in our way. We tune in to the things we don’t have — material items, body type, status, money, perfect relationships. But when we view our world from this perspective, we set ourselves up to measure our worth by our deficits rather than our successes.
Feelings of insufficiency, imperfection and envy are known barriers to happiness. When we harbor these feelings, we limit our capacity for feeling happy and fulfilled.
Although we often strive to find happiness and success by working toward that which we covet, research shows that this approach may be holding us back. It’s actually the practice of noticing and appreciating what we already have that will bring more happiness.
Feeling gratitude for what’s going well in life has a remarkable impact on how we feel about ourselves and the world around us. Indeed, positive psychology research demonstrates that gratitude is strongly associated with greater happiness and fulfillment.
Gratitude has powerful effects on health and well-being
Research shows that gratitude has powerful effects on physical health, social relationships, and self-worth. Experiencing gratitude also builds the mental and physical resilience needed to overcome life’s stresses and challenges.
Robert Emmons, a leading researcher on the effects of gratitude, has conducted decades of research showing that gratitude improves both physical and psychological well-being. Emmons has studied people of all ages to demonstrate the wide-reaching impact of gratitude on the human experience — on our personal satisfaction, social connectedness and physical health.
Emmons has found that people who regularly practice gratitude report higher levels of positive emotions, including more joy, pleasure, happiness, and optimism. These people also tend to have stronger social relationships and fewer feelings of isolation —> Read More
ESPOO, Finland, May 6 (UPI) — Researchers in Finland have developed a tiny sensor that can detect food spoilage by picking up expelled ethanol. The sensor can send results to a smartphone. —> Read More
By changing mouse genes to block a protein associated with obesity, scientists have prevented fat from forming around the animals’ internal organs, even when the animals eat an unhealthy diet. The study found that these genetically engineered mice also retained their sensitivity to insulin (normally blunted by obesity), despite gaining weight. —> Read More
Mining pop’s digitised “fossil record” to identify key revolutions since 1960 is laudable but there are plenty of missing links, says John Covach

Biologists have discovered a new microbe that represents a missing link in the evolution of complex life. The study provides a new understanding of how, billions of years ago, the complex cell types that comprise plants, fungi, but also animals and humans, evolved from simple microbes. —> Read More
Technology in common household humidifiers could enable the next wave of high-tech medical imaging and targeted medicine, thanks to a new method for making tiny silicone microspheres. The researchers made silicone microspheres with a variety of properties for different applications, including colored, fluorescent and magnetic spheres. —> Read More
