How to tackle the global deforestation crisis

Imagine if France, Germany, and Spain were completely blanketed in forests — and then all those trees were quickly chopped down. That’s nearly the amount of deforestation that occurred globally between 2001 and 2020, with profound consequences.  Deforestation is a major contributor to climate change, producing between 6 and 17 percent of global greenhouse gas emissions, according to a 2009 study. Meanwhile, because trees also absorb carbon dioxide, removing it from the atmosphere, they help keep the Earth cooler. ...

Language acquisition may work differently in people with autism

You’re looking at a truck. You’re with a young child and he follows your gaze. He’s interested in the object you’re looking at without you pointing at it. This is called joint attention and it is one of the primary ways children learn to connect words with objects and acquire language. Lack of joint attention is a core feature of autism. Until now, it was thought that stimulating joint attention in people with autism would help them express themselves verbally. But a meta-analysis of 71 studies on autism challenges this assumption and suggests that people with autism spectrum disorders may acquire language differently. The study – by Laurent Mottron, ...

Upgrading iron and steel plants could save equivalent of two years of global carbon emissions

Upgrading, or retrofitting, the world's iron and steel processing plants early could reduce carbon emissions by up to 70 gigatonnes by 2050, roughly equivalent to two years' worth of net global carbon emissions, according to a new study led by UCL researchers. Published in the journal Nature, the researchers found that by upgrading the world’s iron and steel production facilities, carbon emissions can be reduced by 58.7 gigatonnes between 2020 and 2050, roughly equivalent to two years’ worth of net global carbon emissions. ...

Genetically modifying individual cells in animals

One proven method for tracking down the genetic causes of diseases is to knock out a single gene in animals and study the consequences this has for the organism. The problem is that for many diseases, the pathology is determined by multiple genes. This makes it extremely difficult for scientists to determine the extent to which any one of the genes is involved in the disease. To do this, they would have to perform many animal experiments – one for each desired gene modification. Researchers led by Randall Platt, Professor of Biological Engineering at the Department of Biosystems Science and Engineering at ETH Zurich in Basel, have now developed a method that will greatly ...

Consumption of ultraprocessed food and risk of depression

About The Study: The findings of this study suggest that greater ultraprocessed food (UPF; i.e., energy-dense, palatable, and ready-to-eat items) intake, particularly artificial sweeteners and artificially sweetened beverages, is associated with increased risk of depression. Although the mechanism associating UPF to depression is unknown, recent experimental data suggests that artificial sweeteners elicit purinergic transmission in the brain, which may be involved in the etiopathogenesis of depression.  Authors: Raaj S. Mehta, ...

Strengthening artificial immune cells to fight cancer

Among available immunotherapies, the use of «CAR-T» cells is proving extremely effective against certain blood cancers, but only in half of patients. A main reason for this is the premature dysfunction of these immune cells, which have been artificially modified in vitro. A team from the Universities of Geneva (UNIGE), Lausanne (UNIL), the Geneva University Hospitals (HUG) and the Vaud University Hospital (CHUV), all part of the Swiss Cancer Center Léman (SCCL), has discovered how to prolong the functionality of CAR-T cells. By inhibiting a very specific metabolic mechanism, the team has succeeded ...

Scientists reveal how the effects of psychosis spread throughout the brain

Psychoses like schizophrenia cost billions of dollars annually and derail the lives of people struggling with the disease. Now Monash University researchers have modelled how the effects of psychosis spread through the brain, allowing them to isolate areas where these changes may originate from and which could be targeted by therapies designed to reduce the disease’s progression. The study, published today in the prestigious Journal of the American Medical Association Psychiatry, details how the scientists were able to map and model the spread of brain changes in people with different stages of psychoses such as schizophrenia,from people newly ...

Scientists researched on finite-time anti-saturated proximity control with a tumbling non-cooperative space target

The past few decades have witnessed the burgeoning development of on-orbit servicing in light of various meaningful space applications such as repair of malfunctioning satellites, debris removal, on-orbit assembly, and so on. As for the orbit-servicing targets, they are usually divided into 2 categories, i.e., cooperative and non-cooperative ones, based on whether the space targets have active cross-link communication and cooperative identifiers with the servicing spacecraft or not. Before executing the orbit-servicing task, close-range rendezvous and proximity is an inevitable process in which ...

A study published in Chinese Medical Journal reveals potential of methotrexate to treat liver cancer

Liver cancer is one of the most prevalent and deadly types of cancer worldwide. Most patients are diagnosed at an advanced stage, which leaves them with few treatment options. Unfortunately, the first-line drugs used in advanced hepatocellular carcinoma (HCC), the most common type of liver cancer, are not very effective and offer only modest clinical benefits. Over the past few years, scientists have been trying to develop new therapies for HCC by analyzing specific genetic abnormalities and the ways in which they affect the manifestation and progression of the disease. One of the most common mutations in HCC ...
