US Congress commits to act on climate crisis, despite Donald Trump

Nancy Pelosi tells UN conference in Madrid that commitment is ‘iron-clad’The US will take action on greenhouse gases and engage with other countries on the climate emergency despite Donald Trump’s rejection of international cooperation, a delegation from the US Congress has told the UN climate conference in Madrid.Nancy Pelosi, the speaker of the House, struck a defiant stance on Monday,...

New strategies against bone metastases from prostate cancer

A study suggests a new approach, or, possibly two new approaches against prostate cancer bone metastases: While targeted therapies and anti-cancer immunotherapies have not been especially successful against primary prostate cancers, the study suggests that both these approaches may be effective against the bone metastases that grow from primary prostate cancers, and, in fact, the type of bone...

Reflecting on photos helps young cancer survivors regain confidence

Young cancer survivors face unique medical and psychosocial challenges that can hinder their ability to move on mentally and socially, even years after their final treatment. Lingering feelings of isolation and loss can contribute to a lack of confidence and self-efficacy, or the sense that they will be able to handle whatever arises in the future. But new research suggests survivors who retell...

Sustaining roads with grape and agricultural waste

The US spends $5 billion a year to repair damages to road infrastructure from winter snow and ice control operations and the use of traditional deicers. A team of researchers is developing a more sustainable solution using grape skins and other agricultural waste.

Why stress doesn't always cause depression

Rats susceptible to anhedonia, a core symptom of depression, possess more serotonin neurons after being exposed to chronic stress, but the effect can be reversed through amygdala activation, according to new research in JNeurosci.

Usman Khan, sentencing and the rehabilitation of serious offenders | Letters

Peter Lock, a former probation officer, and psychotherapist Tricia Scott on jail conditions that can do more harm than good to prisonersAs a retired probation officer who was involved in the delivery of training programmes for the Criminal Justice Act 2003, I would suggest that the inadequacy of sentencing in Usman Khan’s case was rooted in the manner in which imprisonment for public protection...

Tiny woodlands are more important than previously thought

Small woodlands in farmland have more benefits for humans per area, compared to large forests according to a new study. The small woodlands, sometimes even smaller than a football field, can easily go unnoticed in agricultural landscapes. Yet, these small forest remnants can store more carbon in the topsoil layer, are more suitable for hunting activities and host fewer ticks than large forests.

Sweet potato uses a single odor to warn its neighbors of insect attack

A single volatile substance can be sufficient to induce a defense response in sweet potatoes to herbivores. Researchers have identified this substance and shown that the mechanism is not only limited to the attacked plant itself but also alerts unaffected neighboring plants to defend themselves against attackers. This response is specific and not observed in every sweet potato cultivar. The...

A trick for taming terahertz transmissions

Researchers have invented a wireless communication receiver that can operate in the terahertz frequency band. By increasing the sensitivity 10,000-fold, they achieved the fastest Researchers invent a new receiver for terahertz-frequency radiation -- by implementing coherent detection, they achieve record transmission rates -- this work may lead to much faster wireless data speeds using less...

Protein defect leaves sperm chasing their tails

Researchers have characterized a protein, called VSP, that keeps sperm swimming in straight lines. Deletion of the protein caused sperm to swim in circles, significantly reducing fertilization rates. VSP also controlled the influx of calcium ions into the flagellum, which is necessary for propulsion of the sperm towards the egg. The researchers hope that their discovery will aid in the development...

Deep learning identifies molecular patterns of cancer

An artificial intelligence platform can analyze genomic data extremely quickly, picking out key patterns to classify different types of colorectal tumors and improve the drug discovery process. The deeper analysis shows some colorectal subtypes need to be reclassified.
