Cheruvayal Raman was pained to see native rice varieties lose to hybrid seeds. So, he started cultivating native paddy and preserving their seeds. Watch his journey.

Recently, a start-up company called Make Sunsets has begun releasing chemicals into the stratosphere as a form of geoengineering that is intended to help climate change. However, many are very hesitant about the startup and the result of what they are doing.
For perspective, geoengineering is when chemical particles are released into the stratosphere to manipulate the weather or climate. The theory is that when sulfur is released into the atmosphere that it mimics a natural process that occurs after volcanoes and that by doing this intentionally, we could ease global warming.
While it isn’t difficult to do this, it is very controversial. The reason for this is that it could potentially have dangerous side effects. Additionally, because some regions could endure worse side effects, it could cause issues across international lines.

New insights into the opposing actions of serotonin-producing nerve fibers in mice could lead to drugs for treating addiction and major depression.
Scientists in Japan have identified a nerve pathway involved in the processing of rewarding and distressing stimuli and situations in mice.
The new pathway, originating in a bundle of brain stem nerve fibers called the median raphe nucleus, acts in opposition to a previously identified reward/aversion pathway that originates in the nearby dorsal raphe nucleus. The findings, published by scientists at Hokkaido University and Kyoto University with their colleagues in the journal Nature Communications, could have implications for developing drug treatments for various mental disorders, including addiction and major depression.
Research at the Institute of Molecular Biology and Biotechnology (IMBB) of the Foundation for Research and Technology-Hellas (FORTH), published today in the journal Nature Aging, reveals a fundamental quality control mechanism that operates in cells to safeguard the integrity and function of the nucleus. By maintaining nuclear homeostasis, this molecular mechanism contributes critically to promote longevity and fertility.
IMBB researchers Dr. Margarita-Elena Papandreou and Dr. Georgios Konstantinidis, headed by Dr. Nektarios Tavernarakis (Professor at the Medical School, University of Crete, and Chairman of the Board at FORTH), discovered that recycling of nuclear and nucleolar components via autophagy delays aging of somatic cells, and sustains the immortality of germ cells, which are required for reproduction.
The nucleus is the central organelle of all eukaryotic cells that contains the genetic material (DNA), which determines cellular identity and function. During aging and in cancer cells, the ultrastructure of the nucleus is dramatically altered. Moreover, progressive and pronounced deterioration of the nuclear architecture is a common and conserved feature of progeria and numerous other disorders associated with aging.
Like so many on-screen action heroes, she was elbowed aside when newer stars appeared and started grabbing more viewers with bigger weapons, better special effects and more elaborate adventures.
That’s when Lars Wingefors spied an opportunity and swooped in.
Earlier this year, the little-known Swedish billionaire bought the rights to British archaeologist Lara Croft and the vehicle that turned her into a household name. After debuting 26 years ago, “Tomb Raider” went on to become one of the best-selling video game franchises of all time, spawning lucrative spinoffs and movies starring Angelina Jolie and Alicia Vikander, before faltering as bigger games and mobile apps appeared and gaming moved away from its core teenage male audience to young girls, college students and families.
Although the toxicity of graphene‐based nanomaterials on human health has been extensively studied, their impact on the microbiome remains poorly understood. Using zebrafish as a model, we show that graphene oxide modulates the immune system in a microbiome‐dependent manner through a mechanism mediated by the aryl hydrocarbon receptor. The study suggests an interplay among graphene‐based nanomaterials, microbiome and innate immune system.
For nearly two decades, astrophysicists have believed that long gamma-ray bursts (GRBs) resulted solely from the collapse of massive stars. Now, a new study upends that long-established and long-accepted belief.
Led by Northwestern University.
Established in 1,851, Northwestern University (NU) is a private research university based in Evanston, Illinois, United States. Northwestern is known for its McCormick School of Engineering and Applied Science, Kellogg School of Management, Feinberg School of Medicine, Pritzker School of Law, Bienen School of Music, and Medill School of Journalism.
New research in Biological Psychiatry offers the first direct evidence of diminished 5-HT release cements “serotonin hypothesis.”
Researchers have postulated since the 1960s that major depression stems from disruptions in the serotonin neurotransmitter system. However, the evidence for that idea, though plentiful, was indirect. In fact, a recent comprehensive analysis of existing studies concluded that there was not strong evidence to support the “serotonin hypothesis.” In its wake, some in the field have called for a reexamination of the hypothesis. Not so fast, says a new study that provides direct evidence of disrupted serotonin release in the brains of individuals with depression.
The study was published recently in the journal Biological Psychiatry.
