This 16-year-old high school student from Iloilo went viral after discovering the properties of Aratiles fruit or Sarisa that can cure diabetes.

The young Filipina scientist was identified as Maria Isabel Layson, was one of the winners of the 2019 National Science and Technology Fair (NSTF), that was held last February.

She was also one of the 12 candidates sent to the International Science and Engineering Fair in Phoenix, Arizona USA to represent the Philippines in one of the biggest pre-college science research competition in the world and was the first in her batch to receive Gokongwei Brothers Foundation Young Scientist Award.

How do we find other planets?
For life in the universe to be abundant, planets must be abundant. But planets are hard to detect because they are small, and much fainter than the stars they orbit.

How does life begin?
Scientists do not yet know how the first living things arose on Earth. The geological record shows that life appeared on Earth almost as soon as the young planet was cool and stable enough for living things to survive. This suggests that life may exist wherever conditions allow it.

Earlier today, Genevieve O’Hagan updated Lifeboat readers on this week’s momentous event in Astronomy. At least, I find it fascinating—and so, I wish to add perspective…

30 years ago, astronomer Jack Hills demonstrated the math behind what has become known as the “Hills Mechanism”. Until this week, the event that he described had never been observed.* But his peer astronomers agreed that the physics and math should make it possible…

Hills explained that under these conditions, a star might be accelerated to incredible speeds — and might be even flung out of its galaxy:

• Suppose that a binary star passes close to a black hole, like the one at the center of our galaxy
• The pair of self-orbiting stars is caught up in the gravity well of a black hole, but not sucked in

If conditions are right, one star ends up orbiting the back hole while the other is jettisoned at incredible speed, yet holding onto its mass and shape. All that energy comes from the gravity of the black hole and the former momentum of the captured star. [20 sec animation] [continue below]

This week, astronomers found clear evidence of this amazing event and traced it back to our galactic center: Five million years ago — as our ancestors learned to walk upright — a star that passed close to the massive black hole at The Milky Way center was flung away at a staggering 6 million Kmh. It is traveling so fast, that it is no longer bound to our galaxy or galactic cluster. It is headed out of the galaxy.

• Rifle Bullet: Can exceed Mach 3 (2,300 mph)
• Apollo Rocket: Reached 25,000 mph; Earth escape velocity.
• Juno Probe: 165,000 mph, a record prior to 2019. (It used Jupiter’s gravity to accelerate)
• Parker Probe: 213,000 mph (Nov 2019), but will soon reach 430,000 in a tight arc around the Sun

Walking, talking holograms have been a staple of sci-fi films since Princess Leia was magically brought to life in “Star Wars”.

Now scientists in Britain say they can make even more realistic 3D versions—a butterfly, a globe, an emoji—which can be seen with the naked eye, heard and even felt without the need for any virtual reality systems.

Writing in the journal Nature, a team at the University of Sussex in southern England, said technology currently in use can create 3D images but they are slow, short-lived and “most importantly, rely on operating principles that cannot produce tactile and auditive content as well”.

Death means an end, but one recent research challenges the idea and fuels the possibility of reviving the brain. And it has plunged the scientific community into an ethical debate.

Physical movements, thoughts, and actions are traits that define how we know the difference between what’s alive and what’s lifeless i.e. death. But beyond that, we hardly understand what death means. We’ve known that death is an eventuality and irreversible. But recent research done back in April 2019 changed all that. Consequently, science is making us rethink the definition of death and the sheer fact that it is permanent.

But Manichean views and tropes of ‘dual use’ miss the point. Some of the key questions that confront science today are about whether its methods, practices and ethos, pursued with very little real change since Maxwell’s day, are fit for purpose in the light of the challenges — conceptual and practical — we now face. Can science continue to fulfil its social contract and to reach new horizons by advancing on the same footing into the future? Or does something need to shift?

Research cannot fulfil its social contract and reach new horizons by advancing on the same footing into the future, argues Philip Ball in the last essay of a series on how the past 150 years have shaped today’s science system, to mark Nature’s anniversary.

Both Marie Curie and Lise Meitner, the only two women to be immortalized on the Periodic Table, celebrate the same November 7 birthday. Here are more reasons why they’re remarkable.
