How your life could change the cells of your grandkids

We explain what the new science of epigenetics means for your children and grandchildren.

Everyone's heard of the genome: that double helix DNA code that is uniquely yours, unless you happen to have an identical twin. But there's another layer of complexity responsible for creating us — and that's the epigenome.

Your epigenome sits in your cells with your genome. It's a set of instructions that decides which bits of your DNA are activated, or which genes are switched on or off.

Can you get pregnant during a pregnancy?

The technical term for this is superfetation. In humans, it's possible, but it's very uncommon.

Two thousand years ago, that great Greek thinker Aristotle wondered about this very topic, specifically as regards the hare.

Aristotle noticed that when a hare gave birth, quite often the offspring in a single litter would fall into two distinct classes: there would be a bunch of full-sized robust baby hares, and another bunch of scrawny frail baby hares.

Why your TV, radio and internet might drop out in the next fortnight

But in the fortnight after the autumnal equinox — and the fortnight before the spring equinox — in the southern hemisphere, you may notice that your radio or TV broadcast briefly drops out.

If you're in a regional area, the internet might be patchy, too. What's going on?

What is an equinox?

If you were standing at the geographic equator and looked up during an equinox, you'd see the Sun pass directly overhead.

Can giving girls pink toys and boys blue ones REALLY affect what kind of job they'll get?

That's according to the Institution of Engineering and Technology (IET), which says we should rethink choosing pink presents for girls.

It says 89% of girls' toys are pink but only a small number are focused on science, technology, engineering and maths (Stem).

The IET says that suggests toys are being chosen based on stereotypes.

Business College boasts new Infrastructure

The K2 million government funded infrastructure is one of the many developments undertaken by the school to cope with increasing enrollments.

The hall was formally opened by Minister for Higher Education, Research, Science and Technology, Francis Marus and witnessed by the school board & management, teachers and students.

School Principal, John August, said several other projects were financed by the college itself through fundraising as a communal effort to develop the institution. 

“I believe in doing first before asking.”

K1 million to be given to Oro learning centre

The centre which is a former campus of the University of Natural Resources and Environment (UNRE) will receive the funding promised to it.

Minister for Higher Education, Research and Technology, Malakai Tabar, said this to Ijivitari MP, David Arore, when queried about the funds and if the institution would be ready by next year.

“My Secretary has given instruction to the Vice Chancellor of UNRE to return the funds that were parked under UNRE to transfer it to the department then the department will look at allocating that K1 million to Oro Campus,” said Tabar.

OHE to issue tickets to sponsored students only

The Department of Higher Education and Research, Science and Technology secretary Professor David Kavanamur made this statement in a media release.

He added that all international students from Solomon Islands and Vanuatu, under the bilateral scholarship agreements between the PNG Government and their respective governments, will be issued tickets if they wish to return.

Tickets will be collected at Air Niugini offices nationwide. 

Mellam: Transformation critical for State-owned universities

UPNG vice chancellor Professor Albert Mellam called on Minister for Higher Education, Research, Science and Technology, Francis Marus, to work together with the universities for better results.

Mellam said the universities and institutions of higher education in this country are at the crossroads of their existence to secure a place in a highly competitive higher education sector globally.

Mellam highlighted a number of critical challenges that must be addressed in collaboration with all the stakeholders that make up the higher education sector in PNG.
