Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas sensing and optical computing. Now, applied physicists have invented a new type of interferometer that allows precise control of light's frequency, intensity and mode in one compact package.

A species of houndshark called Mustelus lenticulatus makes sharp clicking noises when handled. Until now, sharks as a group were thought to be universally quiet

What happens when you mix clouds of gas and dust, strong outflows, and energetic shock waves at the core of the Milky Way Galaxy? Space tornadoes. At least, that's how researchers using the Atacama Large Millimeter Array in Chile to study the galaxy's heart described what they found.

There's a well-established paradigm in planetary body exploration. It begins with a flyby, then later an orbiter, and then, if possible, a lander. Previous spacecraft have performed single flybys of Europa, and the Europa Clipper orbiter is on its way to Jupiter's moon Europa for a more detailed orbital study of the frozen moon. Hopefully, a lander will follow. A presentation at the recent Lunar and Planetary Science Conference showed how the Europa Clipper can help find the best landing sites on the icy ocean moon for a future Europa lander.

The James Webb Space Telescope has given us a view of the earliest moments of galaxy formation in the Universe. It's also revealed a few surprises. One of these is the appearance of small, highly redshifted objects nicknamed "little red dots (LRDs)." We aren't entirely sure what they are, but a new study points to an answer.

Even with significant expansion in the global market for antibodies used in clinical care and research, scientists recognize that there is still untapped potential for finding new antibodies. Many proteins group together in what are called protein complexes to carry out biological functions. The traditional method of generating antibodies by immunizing animals struggles to make antibodies related to these protein complexes. Scientists have now demonstrated that fusing protein complexes together adds stability during immunization and enables antibody generation.

Alert to DOGE: Taxpayer money is going to be wasted starting today as the House Oversight and Government Reform Committee begins public hearings into the JFK assassination.

Representative Anna Paulina Luna, the chairwoman of the newly created Task Force on the Declassification of Federal Secrets, has said that the JFK assassination is only the first of several Oversight Committee investigations. Others include the murders of Senator Robert F. Kennedy, the Reverend Dr. Martin Luther King, Jr; the origins of COVID-19; unidentified anomalous phenomena (UAP) and unidentified submerged objects (USOs); the 9/11 terror attack; and Jeffrey Epstein’s client list.

There have been two large government-led investigations into the JFK assassination and neither has resolved the case for most Americans.

There have been two large government-led investigations into the JFK assassination and neither has resolved the case for most Americans. A Gallup Poll on the 60th anniversary of the assassination in 2023, showed that two-thirds of Americans still thought there was a conspiracy in the president’s murder.

I have always advocated for a full release of all JFK files. The American people have the right to know what its government knows about the case. Why, however, spend the task force’s time and taxpayer money investigating the assassination? Representative Luna is not leading an honest probe into what happened. Her public statements show she has already made up her mind that the government is hiding a massive conspiracy from the public and she believes she will expose it.

Representative Luna is not leading an honest probe into what happened.

“I believe there are two shooters,” she told reporters last month at a press conference.

She also said she wanted to interview “attending physicians at the initial assassination and then also people who have been on the various commissions looking into—like the Warren Commission—looking into the initial assassination.”

Rep. Anna Paulina Luna, the chairwoman of the newly created Task Force on the Declassification of Federal Secrets, told reporters: “I believe there are two shooters.”

When it was later pointed out to her that all the members of the Warren Commission are dead, as are the doctors who performed the autopsy on JFK, she backpedaled on X to say she was interested in some Warren Commission staff members who were still alive, as well as several physicians who were at Dallas’s Parkland hospital, where Kennedy was taken after he was shot. Rep. Luna told Glenn Beck on his podcast last month, that she thought the single bullet (Oswald’s second shot that struck both Kennedy and Texas Governor John Connally) was “faulty” and the account of the Dallas Parkland doctors who tried saving JFK “reported an entry wound in the neck….we are talking about multiple shots here.”

The Parkland doctors were trying to save Kennedy’s life. They never turned JFK over on the stretcher on which he had been wheeled into the emergency room. And they did a tracheotomy over a small wound in the front of his throat. Some doctors thought that was an entrance wound. Only much later, when they saw autopsy photographs, did they see an even smaller wound in JFK’s high shoulder/neck that was the bullet’s entrance wound. The hole they had seen before obliterating it with the tracheotomy was the exit of the shot fired by Oswald.

Rep. Luna is determined to interview some octogenarian survivors to get their 62-year-old recollections.

That does not appear to be enough to slow Rep. Luna, who is determined to interview some octogenarian survivors to get their 62-year-old recollections. She is planning even for the subcommittee to make a cold case visit to the crime scene at Dealey Plaza. As I wrote recently on X, “The JFK assassination is filled with researchers who think Oliver Stone is a historian. She will find fertile ground in relying on the hazy and ever-changing accounts of ‘original witnesses.’”

The release of 80,000 pages of JFK files in the past week, and the lack of any smoking gun document, has not dissuaded her investigation.

The release of 80,000 pages of JFK files in the past week, and the lack of any smoking gun document, has not dissuaded her investigation. She has reached out to JFK researchers who are attempting furiously to build a circumstantial and X-Files worthy “fact pattern” that the CIA somehow manipulated Oswald before the assassination. All that is missing in the recent document dump is credible evidence for that theory. It has not stopped those peddling it, however. Nor has it slowed Rep. Luna. 

Last week, she showed the extent to which she had fallen into the JFK rabbit hole. She posted on X, “This document confirms the CIA rejected the lone gun theory in the weeks after the JFK assassination. It's called the Donald Heath memo.” Not quite. The memo she cited is not about the Agency deciding who killed or did not kill Kennedy in the weeks after the assassination. It instead is a memo directing Heath, a Miami-based CIA operative, to investigate whether there were assassination links to Cuban exiles in the U.S. Those exiles, who thought that Kennedy was a traitor for the Bay of Pigs fiasco, were on a short list along with Castro’s Cuba and the KGB on the intelligence agency’s early suspect list. 

Government agencies have undoubtedly failed to be fully transparent about the JFK assassination.

Government agencies have undoubtedly failed to be fully transparent about the JFK assassination. The CIA hid from the original Warren Commission its partnership with the Mafia to kill Fidel Castro. And the Agency slow walked for decades information of what it learned about Oswald’s unhinged behavior at the Cuban and Soviet embassies in Mexico City, only six weeks before JFK visited Dallas. I have written that JFK’s murder might have been preventable if the CIA and FBI had shared pre-assassination information about Oswald. However, political theater that is disguised as a fresh investigation, serves no interest other than feeding the en vogue MAGA conspiracy theories that blame everything on the deep state.

Fossil-fuel plants are increasingly being forced to stop and start production in response to changes in output from renewables. In a new study, researchers developed a dynamic competitive benchmark that accounts for start-up costs and other unit-level operating constraints. They apply their framework to Western Australia, a setting where rooftop solar capacity more than doubled between 2014 to 2018 to world-leading rooftop solar penetration rates. The study found that the large-scale expansion of rooftop solar capacity can lead to increases in the collective profitability of fossil fuel plants because competition softens at sunset--- plants displaced by solar during the day must incur start-up costs to compete in the evening.

A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the geometry and number of 'petals'. This magnetic metamaterial developed by Dr Anna Palau's group at the Institut de Ciencia de Materials de Barcelona (ICMAB) in collaboration with her partners of the CHIST-ERA MetaMagIC project, has now been studied at BESSY II in collaboration with Dr Sergio Valencia. Such a device can be used to increase the sensitivity of magnetic sensors, to reduce the energy required for creating local magnetic fields, but also, at the PEEM experimental station, to study samples under much higher magnetic fields than currently possible.

From virtual reality to rehabilitation and communication, haptic technology has revolutionized the way humans interact with the digital world. While early haptic devices focused on single-sensory cues like vibration-based notifications, modern advancements have paved the way for multisensory haptic devices that integrate various forms of touch-based feedback, including vibration, skin stretch, pressure and temperature. Recently, a team of experts analyzed the current state of wearable multisensory haptic technology, outlining its challenges, advancements and real-world applications.

Compared to the other terrestrial planets, Mercury has always been a bit of a mysterious one. It’s internal structure is very different from its planetary siblings with its core accounting for 70% of its overall mass and an unusually thin mantle composed of silicates. One theory suggests a head-on collision between a larger proto-Mercury and a smaller object while another suggests Mercury sideswiped an Earth-mass object. It may be something completely different and a new paper suggests that a grazing collision between two similarly sized bodies led to the formation of the planet we see today.

Shrouded in thick clouds, our erstwhile sister planet Venus is rife with mysteries. Among the Solar System's rocky planets, Venus is the one begging for more exploration. While potential habitability always catches people's attention, scientists crave more fundamental knowledge about Venus: its geology.

The Moon is a common sight in our night time (and sometimes daytime) skies but it hasn’t always been there. The widely accepted theory of lunar formation involves a Mars-sized planet crashing into the Earth, creating a cloud of debris that eventually that eventually coalesced to form the Moon. Estimates of this cataclysmic event that gave us the Moon range from between 4.52 to 4.35 billion years ago however a new presentation at the Lunar and Planetary Science Conference have pushed that timeline back even further!

Researchers presented advances shaping the world of forensics, from research that could improve how forensic scientists estimate a person's age at death, to technology demos of CSIxR -- a virtual reality (VR) application that simulates crime scenes scenarios to train crime scene investigators (CSIs).

Deep below the Earth's surface, rock and mineral formations lay hidden with a secret brilliance. Under a black light, the chemicals fossilized within shine in brilliant hues of pink, blue and green. Scientists are using these fluorescent features to understand how the caves formed and the conditions for supporting life in extreme, and even extraterrestrial, environments.

The condition of the grass on a golf course can drastically skew the chances of a winning putt regardless of a player's skill. Now, a coating that soaks up water molecules could slow the roll of a golf ball on a lightning-fast, dry course and speed it up on a sluggish, wet course without interfering with the ball when it's airborne.
