Japanese astronomers discover gas giant planets orbiting evolved stars

Using radial velocity method a group of Japanese astronomers has found that two evolved stars, namely 24 Booties and Gamma Librae, are orbited by gas giant planets. They discovered that 24 Booties hosts one planet, while Gamma Librae is circled by two alien worlds. The finding is detailed in a paper published April 11 on arXiv.org.

We think we're the first advanced earthlings—but how do we really know?

Imagine if, many millions of years ago, dinosaurs drove cars through cities of mile-high buildings. A preposterous idea, right? Over the course of tens of millions of years, however, all of the direct evidence of a civilization—its artifacts and remains—gets ground to dust. How do we really know, then, that there weren't previous industrial civilizations on Earth that rose and fell long before human beings appeared?

The gamma ray burst – supernova connection

A "core-collapse" supernova occurs when the iron core of a massive star collapses under the force of gravity and then rebounds, generating pressure waves and shocks that propagate outward. A superluminous supernovae is a rare class of core collapse supernovae whose luminosity, equal to 10-1000 billion suns, is too high to be powered by the usual process that drives supernovae, the radioactive decay of nickel (there is not enough nickel present to do it). The source of the energetics has been hotly contested, with suggestions including shocks from the ejected material or pulsating instabilities interacting with surrounding material. The most favored model, however, is the sustained injection of energy from a source like a spinning compact remnant: a neutron star or an accreting black hole.

How do melanoma cells survive drug treatment long enough to acquire drug resistance?

Cancer often picks up genetic changes that allow it to resist treatment. But this takes time. How do cancer cells undergoing drug treatment survive long enough to evolve? To answer this question, a study presented at the American Association for Cancer Research (AACR) Annual Meeting 2018 used real-time, single-cell imaging to make movies of live cancer cells responding to treatment with an anti-cancer drug. All cells stopped dividing in response to the drug, as expected. And then within 2-3 days, some cells restarted. By rewinding the tape of the cells that tolerated therapy - effectively, playing the movie in reverse - researchers examined how cells are able to evade drug action, long before they have acquired drug resistance mutations.

When prostate cancer reaches bone, bone cells may drive overall growth of the disease

When prostate cancer metastasizes to bone, it can become especially dangerous - not only with its action in the bone but, interestingly, with increased aggressiveness of the overall cancer itself. Now, research presented at the American Association for Cancer Research (AACR) Annual Meeting 2018 hints at why: Cells involved in these bone metastases may release signals that drive the progression of the disease.

Beyond PD-L1: Taking away TIM3 and Tregs stops cancer regrowth after immunotherapy

Radiation treatment can boost the effectiveness of anti-cancer immunotherapy. Still, some patients fail to respond to this combination, and while the combination of radiotherapy and immunotherapy is very good at creating remission, it's not very good at sustaining it. Now a University of Colorado Cancer Center study presented at the American Association for Cancer Research (AACR) Annual Meeting 2018 shows how tumors may learn to overcome this combination treatment: Increased TIM3 and/or increased regulatory T cells (Tregs) within the tumor may help cancers inactivate immune system killer T cells that would otherwise identify and attack the cancer. The findings may help design combination therapies that reduce relapse after immunotherapy.

People with Type 2 diabetes who eat breakfast later, more likely to have a higher BMI

Being an "evening person" is linked to higher body mass indices among people with Type 2 diabetes, and having breakfast later in the day seems to be what drives this association, according to a new paper in the journal Diabetic Medicine.

Is whole-brain radiation still best for brain metastases from small-cell lung cancer?

Lung cancer often metastasizes to the brain. Historically, brain metastases have been treated with whole-brain radiation therapy. However, whole-brain radiation is associated with cognitive side-effects and studies of non-small cell lung cancer patients have shown that a more targeted form of radiation, known as stereotactic radiosurgery, can improve cognitive outcomes and is highly effective for treating limited numbers of brain metastases. However, these studies have usually excluded patients with the related but different form of the disease known as small-cell lung cancer and, for patients with this tumor type, whole-brain radiation remains the standard of care for limited and even solitary brain metastases.

Post-surgical opioids can, paradoxically, lead to chronic pain

Giving opioids to animals to quell pain after surgery prolongs pain for more than three weeks and primes specialized immune cells in the spinal cord to be more reactive to pain, according to a new study by the University of Colorado Boulder.

Fecal microbiota transplantation produces sustained improvements in cognitive and clinical outcomes

A single treatment using an optimized, targeted form of faecal microbiota transplantation (FMT) produces sustained clinical and cognitive improvements, according to the results of a long-term follow-up of patients with liver cirrhosis and hepatic encephalopathy (HE) who had participated in a short-term study. The original, randomized, open label study, which enrolled 20 outpatient men with cirrhosis and recurrent HE receiving standard-of-care (SOC) treatment, had previously reported that a single FMT enema after antibiotic pretreatment improved cognitive function at Day 20 and reduced HE episodes and hospitalizations over the following 5 months compared with SOC. The long-term outcomes of this study, which were presented today at The International Liver Congress 2018 in Paris, France, demonstrated sustained and statistically significant reductions in the number of HE episodes and hospitalizations as well as improvements in cognitive function over 1 year in the men who received FMT compared with the control group.

Updates on new therapies in development for rare liver diseases

Promising results for three drugs for the treatment of three rare liver diseases were presented today at The International Liver Congress 2018 in Paris, France. Sebelipase alfa, approved for treatment of lysosomal acid lipase (LAL) deficiency in 2015, showed sustained improvements and long-term tolerability in a diverse patient population. Preliminary findings with two investigational RNA interference (RNAi) therapeutics were also positive; givosiran substantially reduced the annualized attack rate in patients with acute intermittent porphyria (AIP), and ARO-AAT demonstrated positive preclinical safety and efficacy in alpha-1 antitrypsin (AAT) deficiency—pointing to the developing potential of this new therapeutic strategy in patients with few treatment options. LAL deficiency, an underappreciated cause of cirrhosis and severe dyslipidaemia, is a rare autosomal recessive disorder characterized by accumulation of cholesteryl esters and triglycerides in the liver.25 The age at onset and rate of progression vary greatly.25 Sebelipase alfa is a recombinant human LAL enzyme indicated for the treatment of LAL deficiency which was approved in 2015 following successful Phase 2/3 trials.

Optimizing the use of organs donated from overdose deaths could help to address the national organ shortage

The number of organs donated as a result of overdose death has increased 24-fold since 2000 and transplants with those organs have similar outcomes to transplants with organs donated after trauma or natural death. Optimizing their use is not a solution to the organ shortage, but it could help to address the problem. Findings from a National Registry study are published in Annals of Internal Medicine.

Family support networks in Peruvian barrios prevent child labor

A recent study by the University of Seville Personal and Community Network Laboratory (Laboratorio de Redes Personales y Comunidades) has shown that family support networks have value in preventing child labour. A survey carried out among parents in high-risk contexts shows that schools in barrios on the outskirts of Lima are a central part of life of the community, as they allow families from the district to start and develop relationships with each other; and they serve as points of access for valuable resources from outside the barrio.

Biology news

Scientists discover a pathway that monitors a protein import into mitochondria

If there's one fact that most people retain from elementary biology, it's that mitochondria are the powerhouses of the cell. As such, they break down molecules and manufacture new ones to generate the fuel necessary for life. But mitochondria rely on a stream of proteins to sustain this energy production. Nearly all their proteins are manufactured in the surrounding gel-like cytoplasm, and must be imported into the mitochondria to keep the powerhouse running.

Grafted brain organoids provide insight into neurological disorders

Many neurological disorders—Alzheimer's, schizophrenia, autism, even depression—have lagged behind in new therapies. Because the brain is so complex, it can be difficult to discover new drugs and even when a drug is promising in animal models, it often doesn't work for humans.

A new hope: One of North America's rarest bees has its known range greatly expanded

The Macropis Cuckoo Bee is one of the rarest bees in North America, partly because of its specialized ecological associations. It is a nest parasite of oil-collecting bees of the genus Macropis which, in turn, are dependent on oil-producing flowers of the genus Lysimachia.

Plants play greater role than megaherbivore extinctions in changes to ecosystem structure

Plants may have exerted greater influence on our terrestrial ecosystems than the megaherbivores that used to roam our landscapes, according to new research.

Cytoplasmic streaming is involved in the transmission of signals within giant cells in Chara algae

Chara algae are ancient plant organisms that are commonly found in freshwater reservoirs and occur, though more rarely, in water bodies with salt water. An unusual feature of this type of algae is the huge size of individual cells, which can reach up to one mm in diameter and up to several centimeters in length. This feature makes Characean algae a unique subject for the study of intracellular signals, which are associated with the appearance of signaling molecules in some parts of the cell (for example, when they are touched or illuminated) and their propagation to other cell areas. As these intracellular signals propagate, they cause various physiological responses, including changes in photosynthesis and respiration.

Structure of a protein complex related with cell survival revealed

A team from the Spanish National Cancer Research Centre (CNIO) has determined for the first time the high-resolution structure of a complex (R2TP) involved in key processes for cell survival and in diseases such as cancer. This achievement was made with high-resolution cryo-electron microscopy, a technique brought to the CNIO by Óscar Llorca, director of the Structural Biology Programme and lead author on the paper published in Nature Communications.

Plants use advertising-like strategies to attract bees with colour and scent

Watching plants and pollinators such as bees can teach us a lot about how complex networks work in nature.

Harmful genetic mutations may be less common than we thought

We are all mutants. Every characteristic that defines our species is the result of a genetic mutation somewhere in the history of evolution. And the same is true for every other organism on the planet. Yet more often than not we think about mutations as bad, leading to disability or disease. So how often are these changes to DNA harmful and how many of them are potentially helpful? A new study suggests that lethal mutations may be much less common than we once thought, at least in bacteria.

The Trump administration's new migratory bird policy undermines a century of conservation

The Trump administration has announced a position on protecting migratory birds that is a drastic pullback from policies in force for the past 100 years.

Bold and aggressive behaviour means birds thrive in cities

Most people probably wouldn't consider bustling towns and cities good places for nature to thrive. Yet a few species of birds have so successfully adapted to city living that they boast large and thriving urban populations. Now, research has suggested that the success of these city-dwelling species may lie in their behaviour.

Transfer learning meets livestock genomics

Researchers at Peter the Great St. Petersburg Polytechnic University (SPbPU) have developed a new computational method that predicts harmful mutations in mammalian species. As more livestock producers are using genetic tests to improve their herds, this method will help to optimize and guide the animal breeding programmes, as well as increase the profitability and yields of livestock. Published in Evolutionary Applications, the method follows closely in the footsteps of the most recent innovations in human genomics and translates the knowledge about genetics risk factors in humans to companion animals, thus having a transformative potential for genetics and genomics of livestock species.
