Evidence for life is found on Venus, creating wider access to the best radiotherapy – Medical Physics Web

In this episode the astronomy writer Keith Cooper is on hand to chat about the surprising discovery of phosphine in the atmosphere of Venus. He explains that here on Earth, microbial life is the only natural source of phosphine – which could mean that life exists in the clouds of Venus. Cooper also speculates about how future missions to the “habitable zone” of the Venusian atmosphere could search for life.

Today, there is a huge disparity in cancer care across the world with people living in low- and middle-income countries having limited access to the best radiotherapy treatments. This imbalance is the focus of the social enterprise company EmpowerRT, which was founded by the University of North Carolina medical physicist Sha Chang. In this episode, Chang and her colleague Cielle Collins talk to Physics World’s Tami Freeman about what can be done to provider greater access to the best treatments.

A second crew member has been found alive from a ship carrying livestock that capsized and sank during a typhoon off the southern coast of Japan. But another storm expected to hit the area over the weekend is likely to hamper the search for 40 other people still missing.

42 Crew, Nearly 6,srcsrcsrc Cows Missing After Ship Sinks In Storm-Tossed Seas Off Japan

The Gulf Livestock 1, a 450-foot ship with a cargo of some 5,800 cows en route from New Zealand to China, issued a distress call early Wednesday Japan time near the island of Amami Oshima, north of Okinawa. The ship’s “mayday” was sent from an area affected by Typhoon Maysak, a powerful Category 4 storm.

Japan’s coast guard said Friday that it had rescued Jay-nel Rosals, a 30-year-old Filipino deckhand. Another crew member, chief officer Edvardo Sareno, who was initially identified as Sareno Edvarodo, was located on Wednesday.

Edvardo Sareno, a 45-year-old chief officer from the Philippines of the capsized ship The Gulf Livestock 1, is seen being rescued by Japan’s coast guard on Wednesday. So far, he is one of two survivors from the vessel’s crew of 43.

Japan Coast Guard, 10th Regional Coast Guard Headquarters

Edvardo Sareno, a 45-year-old chief officer from the Philippines of the capsized ship The Gulf Livestock 1, is seen being rescued by Japan’s coast guard on Wednesday. So far, he is one of two survivors from the vessel’s crew of 43.

Rosals was wearing a life jacket and floating in a raft, the coast guard said without elaborating on his condition.

The two found alive are among the 39 crew listed as being from the Philippines. Two others are from New Zealand and two from Australia.

Earlier, a third crew member, who was not identified, was recovered from the water unconscious and facedown, a spokesman for the coast guard said, according to The Associated Press. The man was taken to a hospital, where he was pronounced dead.

Searchers also said they had found a fuel slick on the sea surface and dozens of floating animal carcasses.

After Sareno’s rescue on Wednesday, he told rescuers that the Gulf Livestock 1 was hit broadside by a large wave, capsized and sank. He managed to jump overboard wearing a life jacket but said he did not see any others escape from the sinking ship.

He reportedly asked rescuers: “I’m the only one?”

“I’m so sorry … [I’m] so lucky,” Sareno said, according to the AP.

The Panamanian-flagged vessel is owned and operated by the United Arab Emirates-based Gulf Navigation, which issued a statement about the disaster that was carried by media on Friday.

“Our hearts go out to those onboard and their families at this time,” a Gulf Navigation spokesman said. “We also express deep regret for the sad loss of the livestock onboard. We are monitoring the situation closely and working closely with those involved in rescue efforts. We pray that there are other survivors.”

Typhoon Haishen, bearing down on the same general area affected by Typhoon Maysak earlier this week, was likely to complicate the search for any remaining survivors. Japan’s Meteorological Agency forecasts that by Sunday, Haishen will pass near Okinawa, just south of where the Gulf Livestock 1 went down. The JMA said the storm has the potential to be even more dangerous than Maysak.

Astronomers have found the source of life in the universe – Inverse

Every second, a star dies in the universe. But these stellar beings don’t just completely vanish, stars always leave something behind.

Some stars explode in a supernova, turning into a black hole or a neutron star, while the majority of stars become white dwarfs, a core of the star it once used to be. However, a new study reveals that these white dwarfs contribute more to life in the cosmos than previously believed.

The study, published Monday in the journal Nature Astronomy, suggests that white dwarf stars are the main source of carbon atoms in the Milky Way, a chemical element known to be crucial to all life.

White dwarf stars are a primary source for one of the building blocks of life. NASA and H. Richer (University of British Columbia)

When stars like our own Sun, a yellow dwarf star, run out of fuel, they turn into a white dwarf. In fact, 90 percent of all stars in the universe end up as white dwarf stars.

White dwarfs are hot, dense stellar remains with temperatures that reach 100,000 Kelvin. Over time, billions of years, these stars cool and eventually dim as they shed their outer material. However, right before they collapse, their remains are transported through space by winds that originate from their bodies.

These stellar ashes contain chemical elements such as carbon.

Carbon is the fourth most abundant chemical in the universe and is a key element in the formation of life as it is the basic building block to most cells.

All of the carbon in the universe originated from stars, therefore the phrase that we are made of stars is not only poetic but rather accurate. However, astronomers could not agree on which type of star is responsible for spreading the most amount of carbon across the cosmos.

The scientists behind the new study used observations of white dwarfs in open star clusters, groups of a few thousand stars formed around the same time, in the Milky Way by the W. M. Keck Observatory in Hawaii in 2018.

They measured the stars’ initial-final mass relation, which is the relationship between the stars’ masses when they first formed and their masses as white dwarfs.

Usually, the larger the star was, the more massive a white dwarf will be. However, the study found that the stars’ masses as white dwarfs were larger than the scientists had anticipated considering their initial mass when they first formed.

“Our study interprets this kink in the initial-final mass relationship as the signature of the synthesis of carbon made by low-mass stars in the Milky Way,” Paola Marigo, a researcher at the University of Padua in Italy, and lead author of the study, said in a statement.

The team of scientists concluded that stars bigger than 2 solar masses also contributed to the galactic enrichment of carbon, while stars of less than 1.5 solar masses did not.

“Now we know that the carbon came from stars with a birth mass of not less than roughly 1.5 solar masses,” Marigo said.

The new study suggests that carbon was essentially trapped in the raw material that formed the Solar System 4.6 billion years ago.

Abstract: The initial–final mass relation (IFMR) links the birth mass of a star to the mass of the compact remnant left at its death. While the relevance of the IFMR across astrophysics is universally acknowledged, not all of its fine details have yet been resolved. A new analysis of a few carbon–oxygen white dwarfs in old open clusters of the Milky Way led us to identify a kink in the IFMR, located over a range of initial masses, 1.65 ≲Mi/M≲ 2.10. The kink’s peak in white dwarf mass of about 0.70−0.75 M is produced by stars with Mi ≈ 1.8−1.9 M, corresponding to ages of about 1.8−1.7 Gyr. Interestingly, this peak coincides with the initial mass limit between low-mass stars that develop a degenerate helium core after central hydrogen exhaustion, and intermediate-mass stars that avoid electron degeneracy. We interpret the IFMR kink as the signature of carbon star formation in the Milky Way. This finding is critical to constraining the evolution and chemical enrichment of low-mass stars, and their impact on the spectrophotometric properties of galaxies.

Found Noose

FBI: Noose found in Bubba Wallace’s NASCAR garage was there since last year – Fox News

The FBI has determined that a noose found in NASCAR driver Bubba Wallace’s garage at Talladega Superspeedway on Sunday had been there since at least last year, according to the bureau.

A statement issued by U.S. Attorney Jay E. Town said that an investigation has concluded that no federal crime was committed.

“The FBI learned that garage number 4, where the noose was found, was assigned to Bubba Wallace last week. The investigation also revealed evidence, including authentic video confirmed by NASCAR, that the noose found in garage number 4 was in that garage as early as October 2019,” the bureau said. “Although the noose is now known to have been in garage number 4 in 2019, nobody could have known Mr. Wallace would be assigned to garage number 4 last week.”

Further details were not immediately released. The FBI said no charges would be pursued in relation to the incident.

“The FBI has completed its investigation at Talladega Superspeedway and determined that Bubba Wallace was not the target of a hate crime, NASCAR said in a release after the findings. “The FBI report concludes, and photographic evidence confirms, that the garage door pull rope fashioned like a noose had been positioned there since as early as last fall.”

Wallace — the only full-time African-American driver on the circuit — had become a target for some critics of NASCAR in recent weeks as the face of the series’ response to the current social justice movement taking place across the country and its decision to ban the Confederate flag from its events.

brother Found

One brother was found hanging last week. On Wednesday, another was fatally shot by sheriff’s deputies. – Washington Post

The half brother of Robert Fuller, a young black man found hanging from a tree near a Southern California city hall, was killed by Los Angeles County sheriff’s deputies in a shootout Wednesday, officials say.

According to a statement from the Los Angeles County Sheriff’s Department, Terron Jammal Boone matched the description of a suspect in a kidnapping and domestic assault. Department detectives followed Boone in an attempt to make a traffic stop once they identified him, the statement said.

When the vehicle stopped, Boone opened the front passenger door and fired multiple shots at officers with a handgun, according to the department.

An officer on the scene responded by shooting Boone several times in the upper torso, killing him, officials say.

Authorities said a female driver and a 7-year-old girl were also in the vehicle. The unidentified driver was struck by gunfire and later released from the hospital, and the girl was unharmed, according to the department.

Boone had been charged with assault with a deadly weapon, false imprisonment, domestic violence and criminal threats in Los Angeles County Superior Court the day before his death, the Associated Press reported.

Boone’s relationship to the woman and the girl were not clarified by the sheriff’s department, but the woman was not the accuser in the spousal assault matter, according to the AP.

A handgun was found on the scene and no deputies were harmed in the gunshot exchange, the sheriff’s department said.

The Los Angeles County Sheriff’s Department Information Bureau said in an early-morning statement that it was waiting on coroner and family identification, but an attorney for the family told CNN that the family knows it was Boone who died.

“This afternoon I had to notify the sisters of Robert Fuller that their half brother Terron Jammal Boone was killed by Los Angeles County sheriff’s deputies in Kern County,” Jamon Hicks told the outlet in a statement.

Hicks did not immediately return a request for comment from The Washington Post, but he told CNN that the family and his legal team would not provide additional comment on the incident until they receive all the information about it.

“The family respectfully asks that their privacy be respected,” Hicks told CNN.

The news of Boone’s death comes a little more than a week after his half brother’s body was found hanging from a tree in Palmdale, Calif.

Authorities initially ruled Fuller’s death a suicide, but that conclusion was rejected by his family members, who assert that he was not suicidal, a point his sister, Diamond Alexander, emphasized at a Saturday rally in front of Palmdale City Hall calling for answers.

“We want to find out the truth of what really happened. Everything that they’ve been telling us has not been right,” she told the crowd, according to the Los Angeles Times. “My brother was not suicidal. My brother was a survivor.”

State and federal officials will now oversee an investigation of Fuller’s death, as well as the death of 38-year-old Malcolm Harsch, a homeless black man who was found hanging from a tree in Victorville, Calif., late last month, according to the AP.

Sheriffs in both areas said they are committed to investigating the deaths, despite asserting no evidence of foul play, the AP reported.

Found Half-brother

Half-brother of man found hanged dies in a deputy-involved shooting – CNN

(CNN)The half-brother of Robert Fuller, the 24-year-old black man who was found dead hanging in the city of Palmdale, California, last week, was killed in a deputy-involved shooting in Kern County on Wednesday, according to Fuller’s family attorney.

“This afternoon I had to notify the sisters of Robert Fuller that their half-brother Terron Jammal Boone was killed by Los Angeles County sheriff’s deputies in Kern County,” Jamon Hicks said in a statement.
A public information officer for the Los Angeles County Sheriff’s Department (LASD) was not able to provide details of the incident, which occurred shortly before 5 p.m. Wednesday in Rosamond.
“At this time, until we receive all of the information, the family and their legal team doesn’t have any further comment on this incident. The family respectfully asks that their privacy be respected,” said Hicks.
LASD detectives were at the scene to help in the investigation into the incident. Multiple independent investigations begin immediately at the scene whenever Los Angeles County Sheriff’s deputies are involved in a shooting, the LASD said in a statement.
CNN has reached out to the Kern County Sheriff’s Office for more details.
The Department of Justice and the FBI are reviewing Fuller’s death, which was originally described as an “alleged suicide,” as well as the hanging death of Malcom Harsch 10 days earlier and about 50 miles away in San Bernardino County.

Two black men found hanging

Fire department personnel responded to the scene of Fuller’s death early on June 10, the Los Angeles County Sheriff’s Department said in a statement.
Despite Fuller’s death being consistent with suicide, officials “felt it prudent to roll that back and continue to look deeper,” said Los Angeles County Medical Examiner Coroner Dr. Jonathan Lucas.
Nothing but the rope, the contents of Fuller’s pockets and a backpack he was wearing were found on the scene, according to Los Angeles County Homicide Capt. Kent Wegener.
Investigators are researching Fuller’s medical history, looking for the witness who reported the hanging and searching for contacts in Arizona and Nevada. They will also analyze Fuller’s cell phone and are looking for neighborhood surveillance video.
An autopsy was completed last Friday, but Fuller’s family announced Tuesday that they are seeking an independent investigation and autopsy to determine the cause of his death.
In the second incident, dispatchers in Victorville, received a call on the morning of May 31 from a woman saying her boyfriend, Harsch, hanged himself, according to a news release from the San Bernardino County Sheriff’s Department. The release said Harsch was found at a homeless encampment.
Investigators did not find any evidence of foul play. An autopsy was conducted on June 12 and there are still no signs of foul play, the release said. The forensic pathologist is waiting for toxicology results before assigning the cause and manner of death.

Coronavirus Found

Coronavirus found in semen of COVID-19 survivors; sexual transmission unclear – CBS News

Traces of the COVID-19 coronavirus have been found in the semen of some severely infected men, raising the possibility that the virus might be sexually transmitted, a new study from China claims.

Researchers found evidence of the virus in six men out of a group of 38 COVID-19 patients at Shangqiu Municipal Hospital in China who provided samples.

The six men included four who were still infected and two who were recovering, the researchers said.

The study was led by Dr. Weiguo Zhao of the People’s Liberation Army General Hospital in Beijing, and findings were published May 7 in the journal JAMA Network Open.

It’s not surprising that the virus was found in semen samples, since it’s also been found in stool and other body fluids, said Dr. Ryan Berglund, a urologist with the Cleveland Clinic’s Glickman Urological and Kidney Institute.

Infectious viruses commonly are found in semen, with Zika being one recent notable example. The Chinese researchers noted that 27 different viruses have been detected in human semen.

However, Berglund and infectious disease experts warn that this does not constitute concrete evidence that COVID-19 can be sexually transmitted.

“I think that’s premature,” Berglund said. “You have to look at this as a sign that semen, as along with a number of other body fluids, can contain the virus.”

Dr. Agus on coronavirus antibody tests’ accuracy and how to interpret results

The new paper comes on the heels of another study from China that found no traces of coronavirus in 34 men with mild to moderate cases of COVID-19. That study was published in late April in the journal Fertility and Sterility.

Dr. Amesh Adalja, a senior scholar with the Johns Hopkins Center for Health Security in Baltimore, said “the fact that the novel coronavirus’ genetic material is found in the semen of male patients is an important finding that will need follow-up study.”

Agreeing with the need for further research is Dr. Greg Poland, director of the Vaccine Research Group at the Mayo Clinic in Rochester, Minnesota.

“To me, it raises a warning, and now we have to attend to that warning and do the research,” Poland said.

But both Adalja and Poland have doubts about the potential for COVID-19 to be sexually transmitted.

“We know the virus is transmitted efficiently through the respiratory route and we have not seen any documented cases of sexual transmission, therefore this may not necessarily represent proof of sexual transmissibility via the male genital tract,” Adalja said.

Poland noted that the new study relies on testing that only detects traces of genetic material from the coronavirus.

“It doesn’t tell you that it’s whole, viable, infectious virus,” Poland said. “If I ground up the virus and performed this test, it would be positive even though that virus has no infectious potential.”

Astronomers Have Found a Star That Survived Being Swallowed by a Black Hole – ScienceAlert

(Chandra X-Ray Observatory)


27 APRIL 2020

When black holes swallow down massive amounts of matter from the space around them, they’re not exactly subtle about it. They belch out tremendous flares of X-rays, generated by the material heating to intense temperatures as it’s sucked towards the black hole, so bright we can detect them from Earth.

This is normal black hole behaviour. What isn’t normal is for those X-ray flares to spew forth with clockwork regularity, a puzzling behaviour reported last year from a supermassive black hole at the centre of a galaxy 250 million light-years away. Every nine hours, boom – X-ray flare.

After careful study, astronomer Andrew King of the University of Leicester in the UK believes he has identified the cause – a dead star that’s endured its brush with a black hole, trapped on a nine-hour, elliptical orbit around it. Every close pass, or periastron, the black hole slurps up more of the star’s material.

“This white dwarf is locked into an elliptical orbit close to the black hole, orbiting every nine hours,” King explained.

“At its closest approach, about 15 times the radius of the black hole’s event horizon, gas is pulled off the star into an accretion disk around the black hole, releasing X-rays, which the two spacecraft are detecting.”

The black hole is the nucleus of a galaxy called GSN 069, and it’s pretty lightweight as far as supermassive black holes go – only 400,000 times the mass of the Sun. Even so, it’s active, surrounded by a hot disc of accretion material, feeding into and growing the black hole.

According to King’s model, this black hole was just hanging out, doing its active accretion thing, when a red giant star – the final evolutionary stages of a Sun-like star – happened to wander a little too close. The black hole promptly divested the star of its outer layers, speeding its evolution into a white dwarf, the dead core that remains once the star has exhausted its nuclear fuel (white dwarfs shine with residual heat, not the fusion processes of living stars).

But rather than continuing on its journey, the white dwarf was captured in orbit around the black hole, and continued to feed into it.

Based on the magnitude of the X-ray flares, and our understanding of the flares that are produced by black hole mass transfer, and the star’s orbit, King was able to constrain the mass of the star, too. He calculated that the white dwarf is around 0.21 times the mass of the Sun.

While on the lighter end of the scale, that’s a pretty standard mass for a white dwarf. And if we assume the star is a white dwarf, we can also infer – based on our understanding of other white dwarfs and stellar evolution – that the star is rich in helium, having long ago run out of hydrogen.

“It’s remarkable to think that the orbit, mass and composition of a tiny star 250 million light years away could be inferred,” King said.

Based on these parameters, he also predicted that the star’s orbit wobbles slightly, like a spinning top losing speed. This wobble should repeat every two days or so, and we may even be able to detect it, if we observe the system for long enough.

This could be one mechanism whereby black holes grow more and more massive over time. But we’ll need to study more such systems to confirm it, and they may not be easy to detect.

For one, GSN 069’s black hole is lower mass, which means that the star can travel on a closer orbit. To survive a more massive black hole, a star would have to be on a much larger orbit, which means any periodicity in the feeding would be easier to miss. And if the star were to stray too close, the black hole would destroy it.

But the fact that one has been identified offers hope that it’s not the only such system out there.

“In astronomical terms, this event is only visible to our current telescopes for a short time – about 2,000 years, so unless we were extraordinarily lucky to have caught this one, there may be many more that we are missing elsewhere in the Universe,” King said.

As for the star’s future, well, if nothing else is to change, the star will stay right where it is, orbiting the black hole, and continuing to be slowly stripped for billions of years. This will cause it to grow in size and decrease in density – white dwarfs are only a little bigger than Earth – until it’s down to a planetary mass, maybe even eventually turning into a gas giant.

“It will try hard to get away, but there is no escape,” King said. “The black hole will eat it more and more slowly, but never stop.”

The research has been published in the Monthly Notices of the Royal Astronomical Society.
