of destructive event from a faint small galaxy about 107 billion light years from Earth NASA said (Source: NASA) Related News A mysterious flash of X-rays has been discovered by NASA’s Chandra Observatory in the deepest X-ray image ever obtainedThis source likely comes from some sort of destructive event but may be of a variety that scientists have never seen before NASA said The X-ray source located in a region of the sky known as the Chandra Deep Field-South (CDF-S) has remarkable properties it said Prior to October 2014 this source was not detected in X-rays but then it erupted and became at least a factor of 1000 brighter in a few hours The event likely came from a faint small galaxy about 107 billion light years from Earth NASA said For a few minutes the X-ray source produced a thousand times more energy than all the stars in this galaxy “Ever since discovering this source we have been struggling to understand its origin” said Franz Bauer of the Pontifical Catholic University of Chile “It is like we have a jigsaw puzzle but we do not have all of the pieces” said Bauer Two of the three main possibilities to explain the X-ray source invoke gamma-ray burst (GRB) events GRBs are jetted explosions triggered either by the collapse of a massive star or by the merger of a neutron star with another neutron star or a black hole If the jet is pointing towards the Earth a burst of gamma rays is detected As the jet expands it loses energy and produces weaker more isotropic radiation at X-ray and other wavelengths Also Read:Neptune-sized ‘lost’ planet discovered 3000 light years away Possible explanations for the CDF-S X-ray source according to the researchers are a GRB that is not pointed towards Earth or a GRB that lies beyond the small galaxy A third possibility is that a medium-sized black hole shredded a white dwarf star “None of these ideas fits the data perfectly but then again we have rarely if ever seen any of the proposed possibilities in actual data so we do not understand them well at all” said Ezequiel Treister also of the Pontifical Catholic University The CDF-S source is likely associated with the destruction of a neutron star white dwarf or massive star and is roughly 100000 times more luminous in X-rays It is also located in a much smaller and younger host galaxy and is only detected during a single several-hour burst The research appears in the journal Monthly Notices of the Royal Astronomical Society For all the latest Technology News download Indian Express App More Related NewsA virus that long ago spliced itself into the human genome may play a role in amyotrophic lateral sclerosis (ALS) the deadly muscle degenerative disease that crippled baseball great Lou Gehrig and ultimately took his life That’s the controversial conclusion of a new study which finds elevated levels of human endogenous retrovirus K (HERV-K) in the brains of 11 people who died from the disease “This certainly is interesting and provocative work” says Raymond Roos a neurologist at the University of Chicago in Illinois who treats and studies ALS but who was not involved with the finding Still even the scientists behind the work caution that more research is needed to confirm the link “I’m very careful to say HERV-K doesn’t cause the disease but may play a role in the pathophysiology” says study leader Avindra Nath a neuroimmunologist at the National Institute of Neurological Disorders and Stroke in Bethesda Maryland “The darn thing is in the chromosomes to begin with It’s going to be very hard to prove causation” It was another retrovirus HIV that led Nath to first suspect a connection between viruses and ALS In 2006 he was helping a patient control his HIV infection with antiretroviral drugs when he noticed that the man’s ALS also improved “That intrigued me and I looked in the ALS literature and saw that people had reported they could see reverse transcriptase in the blood” Reverse transcriptase an enzyme that converts RNA to DNA is a hallmark of retroviruses which use it to insert copies of their genes into chromosomes of their hosts No study had ever convincingly found a retrovirus in ALS patients But researchers had only looked for viruses that came from outside the body About 8% of the human genome consists of “endogenous” retroviruses such as HERV-K which presumably are remnants of ancient viruses These retroviruses initially infected a human egg or sperm cell and entrenched themselves in chromosomes allowing them to spread from one generation to the next Mutations ultimately disabled the incorporated retroviral DNA In 2011 Nath and co-workers reported that they had found increased levels of expression for one HERV-K gene in autopsied brains of people who died from ALS Their new study published online today in Science Translational Medicine builds on the earlier work with analyses of more brains and supporting evidence from test tube and mouse experiments In about 10% of people with ALS someone else in the family has the disease which suggests it originated from an inherited aberrant gene Nath and colleagues focused instead on what is known as sporadic ALS: cases in which people have no familial history of the condition Bolstering their 2011 study the team found elevated levels of three different HERV-K genes in the autopsied ALS brains The researchers did not isolate the virus itself which Nath notes is logistically difficult because it would require analyzing “fresh” brains shortly after death The researchers further showed in test tube experiments that adding HERV-K genes to cultures of neurons led to a significant die-off of the cells Using a technique known as electroporation to insert an HERV-K gene into the brains of embryonic mice the researchers showed similar neuronal damage The researchers then engineered mice to express that HERV-K gene in all their neurons Again the gene led to neuronal mayhem and the animals had muscular problems similar to what’s seen in ALS patients Some retrovirologists caution that the evidence remains thin that this endogenous virus causes ALS John Coffin who studies HERV-K at Tufts University in Boston notes that high expression levels of genes from this retrovirus have been found in many conditions including breast cancer multiple sclerosis schizophrenia and melanoma but none have been conclusively shown to be caused by it “There are a lot of papers like this one” Coffin says “Upregulation of this group of endogenous viruses is a very common finding” Coffin says “group” because there are about 90 different HERV-Ks and that’s another concern he has about the Nath lab’s work: The study does not show that all ALS patients had the exact same version of the virus in their brains “I’m perfectly willing to accept that there’s toxicity but I’m never entirely sure what to make of these types of experiments” Coffin says He notes that in 1970s and 1980s so many investigators wrongly asserted that exogenous human viruses—the ones that move between people or commonly humans and animals—caused tumors that they became known as “rumor viruses” “There is a fair amount of rumor virology around endogenous retroviruses causing disease” Even Nath stresses that he wants other labs to confirm his team’s findings “I’ve worked with HIV for many years and I’m aware of the pitfalls and that’s why we wanted to make sure we were very very careful before we stuck our necks out” Nath says “It took us 10 years to produce this paper” Nath is now launching a clinical study that will evaluate the impact of treating ALS patients who have high levels of HERV-K genes expressed in blood with a combination of four antiretroviral drugs used to treat HIV infection The phase I study will primarily assess whether treatment for 24 weeks can lower HERV-K gene expression to undetectable levels but Nath will also monitor the disease’s progression Whether the anti-HIV drugs will even have an impact on HERV-K is unclear The drugs target the reverse transcriptase and protease enzymes which both viruses depend on but differences exist between the HERV-K and HIV versions Coffin who warns that antiretrovirals have toxicities says the clinical trial is folly “The rationale for that is nonexistent” he says Nath counters that there are about 40 cases described in the literature of ALS patients taking antiretrovirals but it’s difficult to make sense of these reports—about half of which claimed improvements “No one has ever done a systematic study” he says Then again Nath allows that increased expression of HERV-K genes in ALS patients may simply be the result of something else that’s causing the actual damage “The reasons for skepticisms are very valid” Nath says “We could be wrong as well”GREENBELT MARYLAND—For months inside the towering Building 29 here at Goddard Space Flight Center the four scientific instruments at the heart of the James Webb Space Telescope (JWST or Webb) have been sealed in what looks like a house-sized pressure cooker A rhythmic chirp-chirp-chirp sounds as vacuum pumps keep the interior at a spacelike ten-billionth of an atmosphere while helium cools it to –250°C Inside the instruments bolted to the framework that will hold them in space are bathed in infrared light—focused and diffuse in laserlike needles and uniform beams—to test their response The pressure cooker is an apt metaphor for the whole project Webb is the biggest most complex and most expensive science mission that NASA has ever attempted and expectations among astronomers and the public are huge Webb will have 100 times the sensitivity of the Hubble Space Telescope It will be able to look into the universe’s infancy when the very first galaxies were forming; study the birth of stars and their planetary systems; and analyze the atmospheres of exoplanets perhaps even detecting signs of life “If you put something this powerful into space who knows what we can find It’s going to be revolutionary because it’s so powerful” says Matt Mountain director of the Association of Universities for Research in Astronomy in Washington DC.
