Scientists discover potentially habitable planets | MIT News
Just 40 light years from Earth, planets are best targets so far for search for extraterrestrial life.

For the first time, an international team of astronomers from MIT, the University of Liège in Belgium, and elsewhere have detected three planets orbiting an ultracool dwarf star, just 40 light years from Earth. The sizes and temperatures of these worlds are comparable to those of Earth and Venus, and are the best targets found so far for the search for life outside the solar system. The results are published today in the journal Nature.

The scientists discovered the planets using TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope), a 60-centimeter telescope operated by the University of Liège, based in Chile. TRAPPIST is designed to focus on 60 nearby dwarf stars — very small, cool stars that are so faint they are invisible to optical telescopes. Belgian scientists designed TRAPPIST to monitor dwarf stars at infrared wavelengths and search for planets around them.

The team focused the telescope on the ultracool dwarf star, 2MASS J23062928-0502285, now known as TRAPPIST-1, a Jupiter-sized star that is one-eighth the size of our sun and significantly cooler. Over several months starting in September 2015, the scientists observed the star’s infrared signal fade slightly at regular intervals, suggesting that several objects were passing in front of the star.

With further observations, the team confirmed the objects were indeed planets, with similar sizes to Earth and Venus. The two innermost planets orbit the star in 1.5 and 2.4 days, though they receive only four and two times the amount of radiation, respectively, as the Earth receives from the sun. The third planet may orbit the star in anywhere from four to 73 days, and may receive even less radiation than Earth. Given their size and proximity to their ultracool star, all three planets may have regions with temperatures well below 400 kelvins, within a range that is suitable for sustaining liquid water and life.

First evidence that sperm epigenetics affect the next generation
A frog study provides the strongest evidence yet that a father’s lifestyle may affect the next generation, via chemical tags that change gene activity

SPERM pass on more than just their DNA. Chemical switches attached to the genomes of sperm – known as epigenetic tags – have been shown to alter the next generation for the first time.

The discovery could explain how a father’s experiences may later affect gene activity in their offspring, a vital step towards improving health and fertility.

Throughout life, our environment changes the activity of our genes, switching them on or off without altering DNA. It does this by epigenetics – adding or removing regulatory chemical tags. Both smoking and diet can alter which genes are tagged in this way, and epigenetic changes have also been linked to cancer.

Over the past decade, a handful of studies have suggested that environmental stressors experienced by parents can also affect the health of their children and even grandchildren. One controversial mouse study suggested that even the fear of a particular smell can be passed down epigenetically (see “Sins of the grandfather“).

Sperm and egg genes can carry epigenetic tags, but it has been difficult to show that these affect offspring. Now Jerome Jullien at the Wellcome Trust CRUK Gurdon Institute in Cambridge and his colleagues have shown for the first time that sperm epigenetic tags do change gene expression in embryos – and that these tags are essential for healthy development.

They made their discovery by comparing frog embryos made from sperm with those made from spermatids, a type of sperm precursor cell. The embryos made from sperm developed much better, but the only difference between sperm and spermatids is their epigenetics.

As spermatids mature into sperm, they lose some of their epigenetic tags – specifically, those that turn genes on. But a second type of tag, which suppresses gene activity, remains. To see if these have any effect on the next generation, the team decided to get rid of them.

No one had managed to do this before, because the DNA in sperm is difficult to manipulate. But the team got around this by engineering eggs to do it for them. They made eggs that had enzymes that remove certain types of tags when the sperm or spermatid is injected into the egg to fertilise it.

By removing different combinations of tags, they discovered that those normally retained in the sperm are important for embryonic development. Removing them leads to abnormal gene expression in the embryo, followed by developmental problems (Genome Research, doi.org/bd66).

It used to be thought that sperm merely delivered the male genetic code to an embryo, says Jullien. “Now we’re showing that there is epigenetic information attached to the sperm that affects the expression of genes in an embryo – and that these genes are important for directing how that embryo develops.” (...)
