Radio emission from a neutron star's magnetic pole revealed by General Relativity

Pulsars in binary systems are affected by relativistic effects, causing the spin axes of each pulsar to change their direction with time. A research team led by Gregory Desvignes from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has used radio observations of the source PSR J1906+0746 to reconstruct the polarised emission over the pulsar's magnetic pole and to predict the disappearance of the detectable emission by 2028. Observations of this system confirm the validity of a 50-year old model that relates the pulsar's radiation to its geometry. The researchers are also able to precisely measure the rate of change in spin direction and find an excellent agreement with the predictions of Einstein's general theory of relativity.

Black hole movies coming soon, says leading astronomer

By the time an international group of scientists stunned the world with the first ever image of a black hole, they were already planning a sequel: a movie showing how massive clouds of gas are forever sucked into the void.

Frequent flaring of Proxima Centauri means bad news for its rocky planet

Proxima Centauri is a cool red dwarf with about one-eighth of the sun's mass. Although it is the closest star to the sun, located just 4.2 light-years from the solar system in the triple star system of alpha Centauri, it is not visible to the naked eye. What makes this star particularly interesting is the recent discovery of an Earth-like exoplanet in its habitable zone: a region around the central star where the presence of liquid water is possible on a planetary surface.

Making sense of Saturn's impossible rotation

Saturn may be doing a little electromagnetic shimmy and twist which has been throwing off attempts by scientists to determine how long it takes for the planet to rotate on its axis, according to a new study.

New insight into how much atmosphere Mars lost

A key tracer used to estimate how much atmosphere Mars lost can change depending on the time of day and the surface temperature on the Red Planet, according to new observations by NASA-funded scientists. Previous measurements of this tracer—isotopes of oxygen—have disagreed significantly. An accurate measurement of this tracer is important to estimate how much atmosphere Mars once had before it was lost, which reveals whether Mars could have been habitable and what the conditions might have been like.

India's Moon mission: Preparing a pitstop for Mars

India is due this weekend to become only the fourth nation after the US, Russia and China to land a spacecraft on the Moon, but there is more at stake than that.

How to spin a disk around young protostars

How do stars and planets form? Scientists are now one step closer to pinning down the conditions for the formation of proto-stellar disks. Observations of three systems in the early stages of star formation in the Perseus cloud revealed that the profile of the angular momentum in these systems is between that expected for a solid body and pure turbulence, indicating that the influence of the core extends further out than previously thought. These findings could lead to more realistic initial conditions for numerical simulations of disk formation.

The stress of extreme living underwater for simulating upcoming Moon missions

As NASA prepares to return to the Moon in the next couple of years and possibly even establish bases, it needs a better understanding of how the human body performs in such an inhospitable habitat.

A globalized solar-powered future is economically unrealistic

Over the past two centuries, millions of dedicated people—revolutionaries, activists, politicians, and theorists—have been unable to curb the disastrous and increasingly globalized trajectory of economic polarization and ecological degradation. This is perhaps because we are utterly trapped in flawed ways of thinking about technology and economy—as the current discourse on climate change shows.

Medicine & Health news

A swifter way towards 3-D-printed organs

Twenty people die every day waiting for an organ transplant in the United States, and while more than 30,000 transplants are now performed annually, there are over 113,000 patients currently on organ waitlists. Artificially grown human organs are seen by many as the "holy grail" for resolving this organ shortage, and advances in 3-D printing have led to a boom in using that technique to build living tissue constructs in the shape of human organs. However, all 3-D-printed human tissues to date lack the cellular density and organ-level functions required for them to be used in organ repair and replacement.

Role of cancer protein ARID1A at intersection of genome stability and tumor suppression

The ARID1A tumor suppressor protein is required to maintain telomere cohesion and correct chromosome segregation after DNA replication. This finding, reported by Wistar researchers in Nature Communications, indicates that ARID1A-mutated cells undergo gross genomic alterations that are not compatible with survival and explains the lack of genomic instability characteristic of ARID1A-mutated cancers.

Preclinical study reveals the impact of age on immunotherapy treatment for breast cancer

Recent clinical trials have indicated that immune checkpoint blockade (ICB) therapy, which is designed to unleash a patient's immune system to attack cancer, has been revolutionary in its implications for breast cancer treatment, especially for its potential to treat patients with triple negative breast cancer (TNBC). Despite the fact that most breast cancer patients are over the age of 60, most clinical trials enroll patients under the age of 60. Age may be an important consideration with respect to ICB, given that aging is associated with profound changes to the immune system, so whether ICB will benefit patients of all age groups is still unknown. In order to understand the influence of aging on the effectiveness of ICB therapy, researchers from Brigham and Women's Hospital, the Dana Farber Cancer Institute, and Harvard Medical School conducted preclinical studies using younger and older mice with TNBC, finding that age affects the efficacy of ICB therapy. The results of this study are published in Cancer Discovery.

Study shows how serotonin and a popular anti-depressant affect the gut's microbiota

New structure for human flu virus protein

Researchers from Oxford University have worked out the molecular structure of a protein that is vital for survival of the flu virus. Recently published in Nature, they used several different techniques to look at the arrangement of atoms within a protein that the human flu virus uses to make new copies of its genetic information. Without this multifunctional protein, known as a polymerase, the flu virus cannot survive. A key finding of the study is that the polymerase can exist in two forms, a monomer and a dimer. It is only when the polymerase dimerises that specific functions are switched on. The research team saw the dimeric form of the polymerase was formed by a specific region of protein and when the region was disrupted, the polymerase couldn't work. This finding presents a brand-new way of potentially inhibiting the flu virus which means we could develop new drugs and flu treatments in the future.

Study answers longstanding cell-development riddle

During the lifetime of a body—whether human, fish or any other type of vertebrate—cells die, making room for fresh new cells to carry on vital processes. The dead cells must be cleared away, though, and debris removal is performed after the embryonic stage by cells of the immune system called macrophages.

Analysis of global cancer data shines light on alternative gen 'switches' in tumors

Scientists from the Agency for Science, Technology and Research (A*STAR)'s Genome Institute of Singapore (GIS) have discovered that many human cancers exhibit widespread alterations in gene activation, where the same gene uses different start positions to generate alternate gene products. These alterations, previously undetected by earlier methods of analysis, may identify novel biomarkers for predicting cancer patient survival and new targets for therapies. The study was published in Cell on 5 September 2019 and featured on the journal's cover.
